Indications and Outcomes of Intraocular Lens Explantation in a Tertiary Eyecare Center in Hungary between 2006 and 2020.

Purpose: Our study aimed to evaluate the indications and outcomes of intraocular lens (IOL) explantation surgeries in a tertiary eyecare center in Hungary. Materials and Methods: This retrospective study included all IOL explantation surgeries performed between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University, Budapest, Hungary. There were no exclusion criteria for this study. For each patient, the demographics, clinical history, preoperative status, indications for IOL explantation, and operative and postoperative details were reviewed. Primary outcomes included explantation indications and the type of secondary implanted IOL. Results: A total of 161 eyes from 153 patients were included (96 males; 62.7%); age at the time of the IOL explantation was 65.0 ± 17.4 years. The mean time between primary cataract surgery and IOL explantation was 8.5 ± 7.7 years. In total, 139 (86.3%) PCIOLs and 22 (13.7%) ACIOLs were explanted. The main indications for IOL explantation were dislocation (n = 133; 95.7%) and refractive cause (n = 2; 1.4%) in the PCIOL group. Among ACIOL explantations, the main reasons were pseudophakic bullous keratopathy (n = 14; 63.6%), dislocation (n = 4; 18.2%), and refractive cause (n = 2; 9.1%). In the PCIOL group, 115 (82.7%) primary IOLs were implanted in the capsular bag, 16 (11.5%) were sulcus fixated, and 8 (5.8%) were scleral fixated. The most frequent ocular comorbidities were previous vitrectomy (n = 50, 31.1%), previous ocular trauma (n = 45, 28.0%), glaucoma (n = 16, 9.9%), pseudoexfoliation syndrome (n = 15, 9.3%), and high axial myopia (n = 14, 8.7%). The most commonly used secondary IOL implant was the prepupillary iris-claw IOL (n = 115, 73.7%), followed by the retropupillary iris-claw IOL (n = 32, 20.5%). Uncorrected visual acuity (UCVA) was significantly better following IOL exchange in the entire sample (1.57 ± 0.61 (range: 2.40-0.05) vs. 0.77 ± 0.56 (range: 2.40-0.00); p < 0.001). Best-corrected visual acuity (BCVA) was maintained or improved in 80.7% of cases after IOL explantation. Conclusions: The most common indication for IOL explantation at a tertiary eyecare center in Hungary is IOL dislocation, followed by pseudophakic bullous keratopathy. Prepupillary and retropupillary iris-claw IOL are the most frequently used secondary implants and their use resulted in a significant UCVA improvement following IOL exchange.

Clinical Characteristics and Treatment of Ophthalmic Sequelae of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis at a Tertiary Eyecare Centre in Hungary.

INTRODUCTION: This study analysed the causative factors and clinical characteristics of acute and chronic ocular sequelae of Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) treated at a large third-referral centre in a developed country (Hungary) over a 15-year period. METHODS: This was a retrospective review of patients with acute and/or chronic SJS/TEN who were managed between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University in Budapest, Hungary. For each subject, clinical data, including patient demographics, clinical history, causative agents of SJS/TEN, and conservative and surgical treatment details, were reviewed. RESULTS: Ninety-six eyes of 48 patients were included (28 female; 58.3%); the age at disease onset was 32.1 ± 22.4 years. The most common causative factors were medicines (n = 36; 75.0%). Among these drugs, 29.2% were nonsteroidal anti-inflammatory drugs (NSAIDs) (n = 14), 20.8% were antibiotics (n = 10) and 14.6% were antiepileptic drugs (n = 7). In patients with chronic SJS/TEN, the most commonly found ocular sequelae were conjunctival hyperaemia in 45 (56.3%) eyes, symblepharon in 38 (47.5%) eyes, trichiasis/distichiasis in 37 (46.3%) eyes, corneal neovascularization in 31 (38.8%) eyes and corneal scarring in 29 (36.3%) eyes. In patients with chronic SJS/TEN, the most frequently used topical conservative treatment included antibiotics in 53 (66.3%) eyes, preservative-free artificial tears in 50 (62.5%) eyes and topical corticosteroids in 42 (52.5%) eyes of 40 patients. The most frequently performed ocular surgeries for managing chronic ocular sequelae in patients with SJS/TEN were epilation for trichiasis (n = 27; 33.8%), cataract surgery (n = 14; 17.5%), entropion surgery (n = 12; 15.0%), penetrating keratoplasty (PK) (n = 11; 13.8%) and amniotic membrane transplantation (n = 4; 5.0%). CONCLUSION: Our results suggest that NSAIDs, antibiotics and antiepileptic drugs are the most common causative factors for SJS/TEN in Hungary. Like in other countries, in Hungary, the ocular management of patients with acute and chronic SJS/TEN is heterogeneous, and most cases do not follow modern therapeutic guidelines.

Evaluation of Retinal Blood Flow in Patients with Monoclonal Gammopathy Using OCT Angiography.

BACKGROUND: Monoclonal gammopathy (MG) is characterized by monoclonal protein overproduction, potentially leading to the development of hyperviscosity syndrome. OBJECTIVE: To assess retinal circulation using optical coherence tomography angiography (OCTA) parameters in patients with monoclonal gammopathy. METHODS: OCTA measurements were performed using the Optovue AngioVue system by examining 44 eyes of 27 patients with MG and 62 eyes of 36 control subjects. Superficial and deep retinal capillary vessel density (VD SVP and DVP) in the whole 3 × 3 mm macular and parafoveal area, foveal avascular zone (FAZ) area, and central retinal thickness (CRT) were measured using the AngioAnalytics software. The OCTA parameters were evaluated in both groups using a multivariate regression model, after controlling for the effect of imaging quality (SQ). RESULTS: There was no significant difference in age between the subjects with monoclonal gammopathy and the controls (63.59 ± 9.33 vs. 58.01 ± 11.46 years; p > 0.05). Taking into account the effect of image quality, the VD SVP was significantly lower in the MG group compared to the control group (44.54 ± 3.22% vs. 46.62 ± 2.84%; p < 0.05). No significant differences were found between the two groups regarding the other OCTA parameters (p > 0.05). CONCLUSIONS: A decreased superficial retinal capillary vessel density measured using OCTA in patients with MG suggests a slow blood flow, reduced capillary circulation, and consequent tissue hypoperfusion. An evaluation of retinal circulation using OCTA in cases of monoclonal gammopathy may be a sensitive method for the non-invasive detection and follow-up of early microcirculatory dysfunction caused by increased viscosity.

Seven-year outcomes following intensive anti-vascular endothelial growth factor therapy in patients with exudative age-related macular degeneration.

BACKGROUND: Anti-vascular endothelial growth factor (VEGF) therapy is currently the most effective therapy of exudative age-related macular degeneration (AMD). The aim of this study was to assess long-term benefits of intensive aflibercept and ranibizumab anti-VEGF therapy in patients with exudative AMD. METHODS: Two clinical trial sites recruited their original subjects for a re-evaluation 7 years after the baseline visit of the phase-3 Vascular Endothelial Growth Factor (VEGF) Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (VIEW 2) trial. Forty-seven eyes of 47 patients with AMD originally treated with ranibizumab (14 eyes) or aflibercept (33 eyes) were included. RESULTS: Mean number of injections was 17.8 ± 3.0 during participation in the VIEW 2 trial. Fourteen of 47 (30%) eyes were given additional injections with a mean number of 5.7 ± 4.5 after the trial. At a mean follow-up time of 82 ± 5 months best corrected visual acuity (BCVA) remained stable or improved (≤ 10 letters lost) in 55% of patients in the entire study population, in 43% in the ranibizumab group and in 60% in the aflibercept group. In both groups combined mean BCVA was 54 ± 13 letters at baseline, 65 ± 17 letters at the end of the intensive phase and 45 ± 25 letters at the end of follow-up. There was no statistically significant difference in BCVA between the two groups at baseline (p = 0.88) and at the end of follow-up (p = 0.40). Macular atrophy was observed in 96% of eyes, average area was 7.22 ± 6.31 mm2 with no statistically significant difference between groups (p = 0.47). Correlation between BCVA at end-of-follow-up and the area of atrophy was significant (p < 0.001). At the end of follow-up, fluid was detected in 7 of 47 eyes (15%) indicating disease activity. CONCLUSION: Long-term efficacy of aflibercept and ranibizumab was largely consistent. Following a two-year intensive therapy with as-needed regimen, BCVA was maintained or improved in almost half of the patients and in the ranibizumab group and more than half of the patients in the aflibercept group with very few injections. In a remarkable proportion of eyes, BCVA declined severely which underlines the need for long-term follow-ups and may indicate a more prolonged intensive therapy.

Intraoperative complication rates in cataract surgery performed by resident trainees and staff surgeons in a tertiary eyecare center in Hungary.

AIM: To compare the incidence of intraoperative complications during primary phacoemulsification (phaco) surgery between resident surgeons (residents) and staff surgeons (specialists) and to objectively determine the difficulty of stages in phaco surgery. METHODS: This retrospective study included cases of phaco cataract surgery performed between January and December 2019. There were no exclusion criteria. For each patient, demographics, clinical history, case complexity, type of surgeon, and operative details were reviewed. Primary outcomes included intraoperative complication rates and the objective measure of difficulty in the steps of the surgery performed by residents and specialists. RESULTS: A total of 3272 cases were included; 7.4% (n=241) of cases were performed by residents. The overall complication rate was 5.4% (n=177). The intraoperative complication rate was significantly higher (P<0.001) in residents (n=33, 13.7%) than in specialists (n=144, 4.8%). The most frequent complications were posterior capsule tear (n=85, 2.6%), anterior capsule tear (n=50, 1.53%), zonular fiber loss (n=45, 1.38%), and dropped nucleus (n=15, 0.46%). Objectively, the most difficult steps during surgery were phaco in 66 (60.0%), capsulorhexis in 21 (19.1%), irrigation/aspiration in 13 (11.8%), hydrodissection in 9 (8.2%), and intraocular lens (IOL) implantation in 1 (0.9%) case. CONCLUSION: Intraoperative complication rates are higher in residents than in specialists. The order of objective difficulty in phaco surgery steps is in line with the subjective findings of other surveys, revealing that the most challenging parts of phaco surgery are phaco and capsulorhexis.

Összefoglaló. Célkituzés: A monoklonális gammopathia szemészeti jeleinek és szövodményeinek vizsgálata. Betegek és módszerek: Két nagy budapesti hematológiai ellátóhely 1999 és 2020 között diagnosztizált és/vagy kezelt, monoklonális gammopathiát mutató betegeit vizsgáltuk (42 beteg 84 szeme, 42,86% férfi; átlagéletkor 63,83 ± 10,76 év). A hematológiai diagnózis 3 esetben bizonytalan jelentoségu monoklonális gammopathia, 34 esetben myeloma multiplex, 3 esetben parázsló myeloma, 1-1 esetben Waldenström-macroglobulinaemia és amyloidosis voltak. Kontrollcsoportként véletlenszeruen kiválasztott, hasonló korcsoportú, hematológiai betegség nélküli egyéneket vizsgáltunk (43 beteg 86 szeme, 32,56% férfi; átlagéletkor 62,44 ± 11,89 év). A szemészeti vizsgálat elott minden személy kitöltötte a Szemfelszíni Betegség Index (OSDI-) kérdoívet. A szemészeti vizsgálat során a látóélesség vizsgálata mellett pupillatágítást követoen réslámpás vizsgálatot végeztünk. Eredmények: Monoklonális gammopathiában az OSDI-érték szignifikánsan magasabb volt, mint a kontrollokban (p = 0,002). Gammopathiában 3 beteg 5 szeménél (5,95%) találtunk potenciális szaruhártya-immunglobulinlerakódást. Gammopathiában szárazszem-betegség 66,67%-ban, szürke hályog 55,95%-ban, Meibom-mirigy-diszfunkció 20,24%-ban, hátsó kérgi szürke hályog 19,05%-ban, egyéb szaruhártyahegek és -homályok 17,86%-ban, krónikus szemhéjgyulladás 14,29%-ban, szemészeti eltérés hiánya 11,90%-ban, macula- és/vagy retinadrusen 9,52%-ban, szaruhártya-immunglobulinlerakódás 5,95%-ban, epiretinalis membrán 5,95%-ban, korábbi szürkehályog-mutét 5,95%-ban, glaucoma 4,76%-ban, Fuchs-dystrophia 2,38%-ban, perifériás retinadegeneráció 2,38%-ban, chorioidea naevus 2,38%-ban, diabeteses retinopathia 1,19%-ban, arteria centralis retinae elzáródás 1,19%-ban, vena centralis retinae ágelzáródás 1,19%-ban, amblyopia 1,19%-ban volt kimutatható. A szárazszem-betegség (p = 0,002), a hátsó kérgi szürke hályog (p = 0,001), a szürke hályog (p<0,00001) és az egyéb szaruhártyahegek és -homályok (p = 0,01) szignifikánsan magasabb arányban fordultak elo a monoklonális gammopathiát mutató betegekben, mint a kontrollokban. Következtetés : Monoklonális gammopathiában a szárazszem-betegség és a szürke hályog a leggyakoribb szemészeti eltérés. A monoklonális gammopathia potenciális szemészeti jelei és szövodményei miatt javasoljuk a betegek évenkénti szemészeti ellenorzését, életminoségük javítása érdekében. Orv Hetil. 2021; 162(38): 1533-1540. OBJECTIVE: To examine ocular signs and ocular comorbidities in monoclonal gammopathy. PATIENTS AND METHODS: We analyzed patients from two large referral hematology centers in Budapest, who were diagnosed and/or treated with monoclonal gammopathy between 1997 and 2020 (84 eyes of 42 patients, 42.86% male, mean age 63.83 ± 10.76 years). Before the ophthalmic examination, the subjects filled in the Ocular Surface Disease Index (OSDI) questionnaire. Ophthalmic examination included visual acuity test and slit-lamp examination following dilation of the pupil. RESULTS: OSDI scores were significantly higher in subjects with monoclonal gammopathy than in controls (p = 0.002). Among gammopathy subjects, we observed potential corneal immunoglobulin deposition in 5 eyes of 3 patients (5.95%). In gammopathy subjects, there was dry eye disease (66.67%), cataract (55.95%), Meibomian gland dysfunction (20.24%), posterior cortical cataract (19.05%), corneal scars and degenerations (17.86%), chronic blepharitis (14.29%), absence of ocular complaint (11.90%), macular or retinal drusen (9.52%), corneal immunoglobulin deposition (5.95%), epiretinal membrane (5.95%), previous cataract surgery (5.95%), glaucoma (4.76%), Fuchs dystrophy (2.38%), peripheral retinal degeneration (2.38%), chorioideal naevus (2.38%), diabetic retinopathy (1.19%), central retinal artery occlusion (1.19%), central retinal vein branch occlusion (1.19%) and amblyopia (1.19%). The proportion of dry eye disease (p = 0.002), posterior cortical cataract (p = 0.001), cataract (p<0.00001), and corneal scars and degenerations (p = 0.01) were significantly higher in gammopathy subjects than in controls. CONCLUSION: Dry eye disease and cataracts are the most common ocular comorbidities in patients with monoclonal gammopathy. Therefore, due to the potential ocular signs and comorbidities of monoclonal gammopathy, we suggest a regular, yearly ophthalmic checkup of these patients to improve their quality of life.

Ocular Signs and Ocular Comorbidities in Monoclonal Gammopathy: Analysis of 80 Subjects.

PURPOSE: To examine the ocular signs of monoclonal gammopathy and to evaluate ocular comorbidities in subjects with monoclonal gammopathy. Patients and Methods. We analyzed patients from two large referral hematology centers in Budapest, diagnosed and/or treated with monoclonal gammopathy between 1997 and 2020. As a control group, randomly selected individuals of the same age group, without hematological disease, have been included. There were 160 eyes of 80 patients (38.75% males; age 67.61 ± 10.48 (range: 38-85) years) with monoclonal gammopathy and 86 eyes of 43 control subjects (32.56% males; age 62.44 ± 11.89 (range 37-86) years). The hematological diagnosis was MGUS in 9 (11.25%), multiple myeloma in 61 (76.25%), smoldering myeloma in 6 (7.50%), and amyloidosis or Waldenström macroglobulinemia in 2 cases (2.50%-2.50%). Before detailed ophthalmic examination with fundoscopy, 42 subjects with gammopathy (52.50%) and all controls filled the Ocular Surface Disease Index (OSDI) questionnaire. RESULTS: The OSDI score and best-corrected visual acuity (BCVA) were significantly worse in subjects with monoclonal gammopathy than in controls (p=0.02; p=0.0005). Among gammopathy subjects, we observed potential corneal immunoglobulin deposition in 6 eyes of 4 (3.75%) patients. Ocular surface disease (p=0.0001), posterior cortical cataract (p=0.01), and cataract (p=0.0001) were significantly more common among gammopathy subjects than in controls (χ 2 test). CONCLUSIONS: Ocular surface disease and cataract are more common, and BCVA is worse in patients with monoclonal gammopathy than in age-matched controls. Therefore, and due to the potential ocular signs and comorbidities of monoclonal gammopathy, we suggest a regular, yearly ophthalmic checkup of these patients to improve their quality of life.

Clinical Review of Ocular Traumas Resulting in Enucleation or Evisceration in a Tertiary Eye Care Center in Hungary.

PURPOSE: To analyse the demographic and clinical characteristics of ocular traumas resulting in enucleation/evisceration in a large tertiary referral center in a developed country (Hungary) over a period of 15 years. Patients and Methods. A retrospective review of enucleated/eviscerated eyes that underwent surgery between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University, Budapest, Hungary, due to ocular trauma as the primary indication for enucleation/evisceration. For each subject, clinical history, B-scan ultrasound report, and histopathology results were reviewed. RESULTS: There were 124 enucleated/eviscerated eyes from 124 patients (91 males (73.4%)). The mean age at the time of trauma was 37.3 ± 26.0 years while the mean age at the time of enucleation/evisceration was 46.9 ± 20.3 years. The main clinical diagnoses after ocular trauma were open globe injury (n = 96; 77.4%), ocular burns (n = 6; 4.8%), traumatic optic neuropathy (n = 4; 3.2%), bulbar avulsion (n = 3; 2.4%), traumatic cataract (n = 2; 1.6%), retinal ablation (n = 1; 0.8%), and traumatic carotid-cavernous fistula (n = 1; 0.8%). Among the 124 patients, 98 (79.0%) underwent enucleation and 26 (21.0%) evisceration. Patients who underwent primary enucleation/evisceration (n = 24 19.4%) were significantly older at the time of the injury (57.7 ± 22.7 years) than people who underwent secondary eye removal (32.4 ± 24.4 years) (p < 0.0001). The mean time interval between trauma and enucleation/evisceration was 114.9 ± 163.5 months. The main clinical indications for anophthalmic surgery were atrophia/phthisis bulbi (n = 56, 45.2%), acute trauma (n = 25, 20.2%), painful blind eye due to glaucoma (n = 17, 13.7%), endophthalmitis (n = 10, 8.1%), and cosmetic reasons (n = 7, 5.6%). One patient (0.8%) had sympathetic ophthalmia. CONCLUSIONS: Primary enucleation/evisceration was performed in one-fifth of all ocular trauma-related anophthalmic surgeries in our tertiary eye care center with enucleation being the most common procedure. Atrophia/phthisis bulbi was the most frequent immediate clinical indication for enucleation/evisceration.

Clinical Review of Microbial Corneal Ulcers Resulting in Enucleation and Evisceration in a Tertiary Eye Care Center in Hungary.

PURPOSE: To analyse the clinical and microbiological characteristics and preexisting ophthalmic and systemic conditions of infectious keratitis resulting in enucleation/evisceration in a large tertiary referral center in a developed country (Hungary) over a period of 12 years. Patients and Methods. A retrospective review of enucleated/eviscerated eyes undergoing surgery between 2007 and 2018 at the Department of Ophthalmology of Semmelweis University, Budapest, Hungary, with infectious keratitis as the primary indication for enucleation or evisceration. For each subject, clinical history, B-scan ultrasound report, and microbiological analyses were reviewed. RESULTS: There were 48 enucleated/eviscerated eyes from 47 patients (29 females (61.7%), age at the time of surgery 66.4 ± 18.5 years). Indication for surgery was hopeless, unmanageable keratitis (62.5%), and keratitis with endophthalmitis (37.5%). The most common preexisting ophthalmic conditions were previous cataract surgery (60.4%), previous therapeutic penetrating keratoplasty (PKP) (56.3%), corneal perforation (52.1%), glaucoma (41.7%), and long-term topical steroid usage (31.3%). In order to treat keratitis, before enucleation or evisceration, 20 eyes (41.7%) underwent PKP, 12 eyes (25.0%) amniotic membrane transplantation, 8 eyes (16.7%) conjunctival autograft transplantation, 6 eyes (12.5%) tarsorrhaphy, and 4 eyes (8.3%) vitrectomy to salvage the eye prior to the final treatment of enucleation or evisceration. The most frequent preexisting systemic diseases were hypertension (62.5%), cardiac disease (20.8%), diabetes mellitus (20.8%), and rheumatoid arthritis (14.6%). Staphylococcus aureus (17.0%) and Propionibacterium acnes (12.8%) were the most commonly isolated gram-positive bacteria, and Pseudomonas aeruginosa was the most frequently isolated gram-negative pathogen bacterium (10.6%). Six globes (12.5%) had positive fungal cultures (1 case of Candida albicans, Candida parapsilosis, Trichosporon inkin, Acremonium sp., Fusarium sp., and Penicillium sp.). CONCLUSIONS: Staphylococcus aureus, Propionibacterium acnes, and Pseudomonas aeruginosa keratitis with or without endophthalmitis represent the most common indication for ocular enucleation/evisceration in patients with microbial keratitis in a tertiary referral center in Hungary. The incidence of enucleation and evisceration related to mycotic keratitis does not seem to have increased within the last decade. Most frequent preexisting systemic diseases in cases of enucleation and evisceration are hypertension, cardiac disease, diabetes mellitus, and rheumatoid arthritis.

Relationship between diabetes mellitus and cataract in Hungary.

AIM: To examine the coexistence of diabetes mellitus (DM) and cataract in Hungary. The effects of DM on the cataract surgical results were also in the focus of analysis. METHODS: Statistical data analysis of the results of the Rapid Assessment of Avoidable Blindness with Diabetic Retinopathy (RAAB+DR) module conducted in Hungary in 2015. This cross-sectional, population-based, national survey included 3523 people aged 50 years and over. Participants of the survey were examined on-site. Visual acuity, main cause for visual impairment (using direct and indirect ophthalmoscopes), in case of best corrected visual acuity (BCVA) ≤0.5 and blood glucose level (random test with glucometer) were examined. RESULTS: The prevalence of cataract was 23.4%, and DM was 20.0%. The occurrence of cataract steadily increased with age. Among the examined participants with DM, the prevalence of cataract was significantly (P=0.012) higher (+35%) than that in non-diabetic subjects (29.5% vs 21.8%). Following aging (OR=15.2%, P<0.001), DM proved to be the most independent influencing risk factor (OR=49.9%, P<0.001). The presence of DM was neither an influencing factor for complications of cataract surgery, nor for postoperative visual acuity. CONCLUSION: DM appears to be one of the main risk factors for developing cataract. Other risk factors, such as age, sex and environment also play an influencing role. Diabetes does not seem to affect the occurrence of cataract surgical complications.

Differential diagnosis and management of melanocytic lesions of the ocular surface / [Pigmentsejt-eredetu szemfelszíni elváltozások differenciáldiagnózisa és kezelése]

Our purpose is to summarize the actual knowledge about melanocytic lesions of the ocular surface (conjunctival nevus, primary acquired melanosis and conjunctival melanoma),especially their clinical appearance, differential diagnosis and treatment. Conjunctival nevus is the most common benign, conjunctival melanocytic lesion. Primary acquired melanosis mainly presents in middle-aged or elderly individuals, characterized by proliferation of melanocytes of the conjunctival epithelial layer. Conjunctival melanoma is a rare tumor, it is the second most common malignant ocular surface tumor after ocular surface squamous neoplasia and the third most common ocular malignancy following choroideal malignant melanoma and ocular surface squamous neoplasia. Early recognition and proper management of conjunctival melanoma is indispensable due to its high malignant and metastatic potential. Due to frequent recurrences, the knowledge and use of intra- and postoperative adjuvant treatment modalities, and regular follow-up are necessary. Orv Hetil. 2020; 161(15): 563­574.

Clinicopathological Review of 547 Bulbar Enucleations in Hungary (2006-2017).

PURPOSE: To analyse current clinicopathological enucleation indications in a large third-referral centre in a developed country (Hungary) over a period of 12 years. METHODS: Retrospective review was performed on 547 enucleated eyes of 543 patients (48.6% males, age 52.7 ± 24.5 years) who were operated on between 2006 and 2017 at the Department of Ophthalmology of Semmelweis University, in Budapest, Hungary. For each subject, clinicopathological data, including patient demographics, indications for enucleation, B-scan ultrasound reports, operative details, and histopathological analyses, were reviewed. Primary enucleation indications were classified into trauma, tumours, systemic diseases, surgical diseases, infections or inflammations, miscellaneous diseases, and unclassifiable groups. Clinical immediate enucleation indications were classified as tumours, atrophia or phthisis bulbi, infection or inflammation, painful blind eye due to glaucoma, acute trauma, threatening or spontaneous perforation, cosmetic causes, and expulsive bleeding. RESULTS: The most common primary enucleation indications were tumours (47.3%), trauma (16.8%), surgical diseases (15.7%), infection or inflammation (11.6%), systemic diseases (5.1%), miscellaneous diseases (2.0%), and unclassifiable diseases (1.5%). Clinical immediate enucleation indications were tumours (46.1%), atrophia or phthisis bulbi (18.5%), infection or inflammation (18.5%), painful blind eye due to glaucoma (11.2%), acute trauma (3.7%), threatening or spontaneous perforation (1.3%), cosmetic reasons (0.5%), and expulsive bleeding (0.4%). CONCLUSIONS: Intraocular tumours represent the most common clinicopathological indication for ocular enucleation in our study population. Following ocular trauma and systemic diseases, the rate of enucleation decreased in the last decade, compared to those previously reported in other developed countries. However, changes were not observed for surgical diseases, infectious and inflammatory causes, or for miscellaneous and unclassified diseases. Orbital implant financing should be increased to ensure better postoperative aesthetic rehabilitation, following enucleation in Hungary.

[Ocular surface squamous neoplasia]. / Szemfelszíni laphám-neoplasia.

To summarize actual knowledge on epidemiology, etiology, pathology, clinical apparence and treatment of ocular surface squamous neoplasias. We summarize up-to-date literature on conjunctival intraepithelial neoplasia and invasive squamous cell carcinoma and present some own cases. Ocular surface squamous neoplasia is the most common malignant ocular surface tumor and the third most common ocular malignancy following malignant melanoma and lymphoma. In spite of its low malignant potential, in advanced stages it may reduce visual acuity significantly or even the eye globe has to be removed. In case of metastasis it may also be life-threatening. As local recurrences of ocular surface squamous neoplasias may occur, knowledge of intra- and postoperative adjuvant treatment options are indispensable and regular control examinations are necessary. Identification and adequate treatment of ocular surface squamous neoplasias are necessary in order to avoid its progression and to prevent recurrences. Orv Hetil. 2017; 158(51): 2011-2022.

[Regional disparities in the prevalence of diabetes and diabetic retinopathy in Hungary in people aged 50 years and older]. / Cukorbetegség és retinopathia diabetica regionális egyenlotlenségei Magyarországon az 50 éves és idosebb korú lakosság körében.

INTRODUCTION: Diabetes mellitus (DM) is one of the main causes of blindness among persons aged 50 years and older. AIM: The purpose of our survey was to estimate the prevalence of DM and diabetic retinopathy (DR), as well as to assess the coverage of diabetic eye care services in different regions of Hungary. METHOD: In 105 clusters, 3675 people aged 50 years and older were included in the survey. The standardized rapid assessment of avoidable blindness (RAAB) with the diabetic retinopathy module (DRM) was used to examine the participants. Thereafter, differences between West-, Middle- and East-Hungary were analysed. RESULTS: Prevalence of DM was higher in East-Hungary (20.9%), than in West- (19.5%) and in Middle-Hungary (19.5%). Prevalence od DR was higher in West-Hungary (24.1%), than in Middle- (17.8%) and in East-Hungary (19.6%). Proportion of participants who never had a fundus examination for DR was the lowest in Middle-Hungary (19.1%). CONCLUSIONS: Primary care should be strenghten mainly in country settlements or telemedical eye screening program should be started to decrease the prevalence of diabetic eye complications. Orv.

[Evaluation of free radical quantity in the anterior chamber following femtosecond laser-assisted capsulotomy]. / Szabadgyök-felszabadulás vizsgálata femtoszekundum lézerrel asszisztált capsulotomiát követoen.

INTRODUCTION: Femtosecond laser is a revolutionary, innovative treatment method used in cataract surgery. AIM: To evaluate free radical quantity in the anterior chamber of the eye, during femtosecond laser assisted capsulotomy, in a porcine eye model. METHOD: Seventy fresh porcine eyes were collected within 2 hours post mortem, were transported at 4 ºC and treated within 7 hours. Thirty-five eyes were used as control and 35 as femtosecond laser assisted capsulotomy group. A simple luminol-dependent chemiluminescence method was used to measure the total scavenger capacity in the aqueous humour, as an indicator of free radical production. The emitted photons were expressed in relative light unit %. RESULTS: The relative light unit % was lower in the control group (median 1%, interquartile range [0.4-3%]) than in the femtosecond laser assisted capsulotomy group (median 4.4%, interquartile range [1.5%-21%]) (p = 0.01). CONCLUSIONS: Femtosecond laser assisted capsulotomy decreases the antioxidant defense of the anterior chamber, which refers to a significant free radical production during femtosecond laser assisted capsulotomy.

[Relationship between corneal surface temperature and air flow conditions during refractive laser eye surgery using three different excimer lasers]. / A szaruhártya felszíni homérséklete és légáramlási viszonyainak alakulása refraktív célú lézeres beavatkozás közben három különbözo típusú és ismétlési frekvenciájú excimer lézerberendezésnél.

INTRODUCTION: Thermal conditions during photorefractive keratectomy might be an important issue related to the corneal wound healing and long-term outcomes. AIM: Authors tried to find out the importance of temperature conditions during the treatment. METHOD: One eye of 90 patients has been included into the study. Photorefractive keratoctomy was applied with Carl Zeiss MEL 70, MEL 80 and Wavelight Allegretto excimer lasers. EBRO TLC 730 infrared thermometer was used for the measurement of surface temperature of the cornea before epithelial removal, as well as before and after the treatment. Average age of the patients was 25.5 ± 3 yr. Average myopic correction was -3.2 ± 0.8 Dpt. RESULTS: Statistically significant difference was found in temperature change between MEL 80 and the other two types of excimer laser devices. CONCLUSIONS: Different air flow conditions of the smoke removal system might have an influence on changes of the corneal temperature during treatment, but the refractive results were not influenced by this issue.

Evaluation of femtosecond laser-assisted and manual clear corneal incisions and their effect on surgically induced astigmatism and higher-order aberrations.

PURPOSE: To evaluate femtosecond laser-assisted and manual clear corneal incisions and their effect on surgically induced astigmatism (SIA) and corneal higher-order aberrations (HOAs). METHODS: In a prospective randomized study, conventional phacoemulsification with a 2.8-mm clear corneal incision using a disposable keratome was performed in 20 eyes of 20 patients (manual group), and femtosecond laser-assisted cataract surgery with a 2.8-mm biplanar clear corneal tunnel created by a femtosecond laser (LenSx; Alcon Laboratories, Inc., Aliso Viejo, CA) was performed in 20 eyes of 20 patients (femtosecond laser group). Corneal topography readings and corneal wavefront aberrations (diameter: 9.0 mm) were obtained using a Scheimpflug camera (Pentacam HR; Oculus Optikgerate, Wetzlar, Germany) preoperatively and 3 months postoperatively. RESULTS: There was no significant difference in SIA between the groups (femtosecond laser group: 0.47 ± 0.13 vs manual group: 0.41 ± 0.14; P = .218), but the axis deviation of the SIA axis from the previously planned axis was significantly smaller in the femtosecond laser group compared to the manual group (4.47°± 2.59° vs 7.38°± 4.72°, respectively; P = .048). Corneal HOAs increased significantly in both groups (femtosecond laser group: 0.13 ± 0.09 to 0.18 ± 0.12, P = .025; manual group: 0.13 ± 0.05 to 0.15 ± 0.05, P = .002), but preoperative and postoperative values did not differ significantly between them (P = .472 and .078, respectively). Lower-order and total corneal aberration values remained stable in both groups (P > .05). CONCLUSIONS: There was no difference in SIA and induced HOAs between manual and femtosecond laser-created clear corneal incisions.

Analysis of planned and postoperatively measured flap thickness after LASIK using the LenSx multifunctional femtosecond laser system.

PURPOSE: To evaluate LASIK corneal flaps using a multifunctional femtosecond laser suitable for cataract and corneal surgery (LenSx; Alcon Laboratories, Inc., Aliso Viejo, CA) and to compare the planned and postoperatively measured flap thickness using an anterior segment optical coherence tomography device (AS-OCT). METHODS: Twenty patients (38 eyes) diagnosed as having myopia and myopic astigmatism were enrolled. LASlK was performed using the LenSx femtosecond laser for intracorneal flaps and the Wavelight Allegretto 400 excimer laser (Alcon Laboratories, Inc.) for intra- stromal photoablation. Desired flap thickness and diameter were 140.0 + 0.0 pm and 8.5 + 0.0 mm, respectively, whereas mean ablation depth and diameter of the excimer laser treatment were 67.9 ± 24.18 pm and 6.5 ± 0.08 mm, respectively. Entered data of the LenSx femtosecond laser were used to determine desired flap thickness, whereas AS-OCT (RTVue; Optovue, Inc., Fremont, CA) was used to measure flap thickness postoperatively. The Wilcoxon signed-rank test, dependent paired t test, and Friedman test were used for comparison of dependent and repeated measures. RESULTS: There was no statistically significant difference in the planned and postoperatively measured flap thickness (140.0 ± 0.0 vs 140.28 _ 8.0 pm; P = .4067). Interfaces of the flaps had even surfaces according to the images and calculations on the AS-OCT device (P = .058). CONCLUSIONS: Application of this multifunctional femtosecond laser performing LASIK proved to be a safe and effective method regarding predictability of flap thickness.

Changes of corneal topography indices after CXL in progressive keratoconus assessed by Scheimpflug camera.

PURPOSE: To evaluate the accuracy of Scheimpflug camera topography indices in detecting the therapeutic effect of corneal collagen cross-linking (CXL) on progressive keratoconus in the long term. METHODS: Fifty eyes of 25 patients with keratoconus were enrolled. CXL was performed in 25 eyes with progressive keratoconus (CXL group) and 25 fellow eyes with nonprogressive keratoconus served as controls. Thinnest corneal thickness, anterior keratometry (flat, steep), and keratoconus indices were measured with Scheimpflug camera before and 12 to 25 months after CXL. Regression analysis was used to evaluate the influence of corneal thickness and follow-up time on flattening effect of CXL. RESULTS: At baseline, steep keratometric values were significantly higher and thinnest corneal thickness values were lower in the CXL group (P = .027, .034), parallel with increased values of keratoconus indices: index of surface variance (P = .013), index of vertical asymmetry (P = .038), keratoconus index (P = .019), center keratoconus index (P = .039), index of height asymmetry (P = .037), index of height decentration (P = .0016), and radius minimum (P = .008). After adjustment for thinnest corneal thickness and follow-up time, CXL showed significant flattening effect expressed by changes in radius minimum (P < .001), index of surface variance (P = .03), keratoconus index (P = .006), center keratoconus index (P = .03), and index of height asymmetry (P = .026). Thinnest corneal thickness had significant influence on changes of index of surface variance (P = .049), index of vertical asymmetry (P = .01), and center keratoconus index (P = .03). Follow-up time showed no significant influence in any models (P > .05). CONCLUSIONS: Topographic indices indicate corneal flattening after CXL in the long term. Monitoring keratoconus index and index of height asymmetry should be the preferred choice in daily clinical practice because changes in values of these indices are independent from initial corneal thickness.

Corneal changes in progressive keratoconus after cross-linking assessed by Scheimpflug camera.

PURPOSE: To evaluate corneal changes after corneal cross-linking (CXL) in progressive keratoconus with Scheimpflug imaging. METHODS: This prospective analysis included 40 eyes from 22 patients with progressive keratoconus. Corneal CXL was performed in 25 eyes (CXL group) and 15 fellow eyes served as controls (control group). Uncorrected (UDVA) and corrected distance visual acuity (CDVA), thinnest corneal thickness (ThCT), posterior elevation, and Holladay equivalent keratometry values (K1, K2) were determined with Pentacam (Oculus Optikgeräte GmbH) before and 1 year after CXL. Area under the receiver operator characteristic (ROC) curve and multivariable general estimating equation models were used to determine the most sensitive parameters of corneal changes. RESULTS: Manifest sphere (-2.55±3.21 to -1.48±2.39 diopters [D], P=.02), UDVA (0.23±0.25 to 0.31±0.25, P<.001), and CDVA (0.58±0.28 to 0.72±0.19, P=.019) improved significantly in the CXL group. Significant decreases were found in ThCT (472.53±33.18 to 440.53±38.67 µm, P<.001), posterior elevation (68.33±28.69 to 22.67±16.21, P<.001), and keratometry values (K1 [45.06±4.55 to 43.51±4.67 D, P<.001], K2 [48.39±5.41 to 46.71±5.67 D, P<.001]) in the CXL group. These parameters remained stable in controls (P>.05). According to ROC analysis, posterior elevation change was the most characteristic parameter of corneal change after CXL (area under the curve=0.99). General estimating equation model showed that CXL (P=.001) and initial ThCT (P=.007) were significant predictors of decrease in posterior elevation with a significant negative interaction of initial ThCT on CXL effect (P=.005). CONCLUSIONS: Posterior elevation is a sensitive parameter to monitor corneal remodeling after CXL. Corneal CXL showed augmented effect on corneal protrusion in eyes with thinner corneas.
