Posterior Chamber Intraocular Lens Dislocation Into the Vitreous in Association With Descemet Stripping Lamellar Keratoplasty.

PURPOSE: The purpose of this study was to report 3 cases of a single-piece, acrylic, foldable, modified C loop posterior chamber intraocular lens (PCIOL) dislocated into the vitreous cavity after Descemet stripping automated endothelial keratoplasty (DSAEK). METHOD: We describe the clinical course and management of the 3 cases in which a previously implanted foldable, single-piece, acrylic posterior chamber intraocular lens with modified C loops dislocated into the vitreous in association with DSAEK. Surgical management consisted of pars plana vitrectomy in each case with either PCIOL repositioning (2 cases) or PCIOL exchange (1 case) and with different fixation methods, combined with repeated DSAEK in 1 case with previous primary graft failure. RESULTS: In 2 cases where the cornea cleared after the DSAEK, the cornea kept its clarity and the PCIOL remained stable. In the third case in which the PCIOL exchange was combined with DSAEK, the cornea only partially cleared up, both the PCIOL and the state of the eye remained stable. CONCLUSIONS: PCIOL dislocation is a possible and notable complication that requires attention while performing DSAEK on pseudophakic eyes. Not only plate-haptic silicone but also acrylic, single-piece PCIOLs with modified C loops may dislocate into the vitreous in association with DSAEK in cases with compromised capsular or zonular integrity.

Herpes simplex virus PCR in 2230 explanted corneal buttons.

PURPOSE: To determine herpes simplex virus (HSV) DNA prevalence and mean cycle threshold of polymerase chain reaction (PCR) in corneal tissue of patients with penetrating keratoplasty (PKP), with (HSK+) and without (HSK-) previous clinical herpetic keratitis history. METHODS: Retrospective review of recipient corneal buttons which were explanted through PKP between March 2010 and September 2018 at the Department of Ophthalmology, Saarland University Medical Center in Homburg/Saar, Germany. Corneal tissue samples were analysed by real-time PCR for the presence of HSV DNA. For each subject, clinical data, including patients' demographics and clinical diagnoses, were collected. RESULTS: In total, 2230 corneal samples (age at the time of the surgery 57.3 ± 19.2 years) of 1860 patients were analysed. HSV PCR was positive in 137 (6.1%) corneal samples, with a 30.57 ± 6.01 (range 14-39) mean cycle threshold (Ct) value. Two hundred ninety-eight (13.4%) corneas of 266 patients were clinically HSK+, and 1932 (86.6%) corneas of 1600 patients were clinically HSK-. HSV DNA was detected significantly more frequently (p < 0.0001) in HSK+ corneal samples (108 corneal samples; 36.2%), than in HSK- corneal samples (29 corneal samples; 1.5%). Ct value was significantly lower in HSK+ than in HSK- corneal samples (29.8 ± 5.8 versus 32.6 ± 5.9; p = 0.008). CONCLUSION: Our data demonstrate that a positive clinical history of HSK is related to HSV PCR positivity in about every 2.8th patient. In addition, about every 66th explanted corneal tissue is HSV PCR-positive despite the lack of clinical suspicion. These patients may need additional local/systemic antiviral treatment to avoid newly acquired HSK following penetrating keratoplasty.

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.

Összefoglaló. Bevezetés: Az elso szaruhártya-bank 1944-es alapítása óta jelentos változásokon ment át. A szaruhártya túlélését számos tényezo befolyásolja, így a tárolási mód, melynek a szövet lejárati ideje szerint rövid, közép és hosszú távú módszereit fejlesztették ki. Célkituzés: Retrospektív vizsgálatunk célja a 2008. január 1. és 2017. december 31. között perforáló és lamelláris keratoplasztika során felhasznált cadaverbol és multiorgan donorból származó szaruhártyák túlélésének vizsgálata volt a Semmelweis Egyetem Szemészeti Klinikáján. Módszer: Feljegyeztük a recipiens nemét, életkorát, a mutétet indikáló klinikai diagnózist, a mutét idopontját, a szövettani vizsgálat eredményét, valamint, hogy a beültetett szaruhártya cadaverbol vagy multiorgan donorból származott. Meghatároztuk, hogy a recipiens életkora korrelált-e a rekeratoplasztikáig eltelt idovel. Eredmények: 1451 szaruhártya-átültetés történt 1088 beteg (44,6% férfi) 1159 szemén (életkor 62,8 ± 18,5 év), melyek között 938 (64,6%) cadaver és 262 (18,0%) multiorgan donor került felhasználásra, 251 esetben (17,2%) nem állt rendelkezésre adat. A leggyakoribb primer diagnózis a szaruhártya-dekompenzáció volt (325 eset, 28%). A primer keratoplasztikák során felhasznált szaruhártyák 740 esetben (63,8%) cadaverbol, 212 esetben (18,2%) multiorgan donorból származtak, 207 esetben (17,8%) nem állt rendelkezésre adat. Elso rekeratoplasztika a primer keratoplasztikák közül 217 esetben (18,7%) történt. A leggyakoribb szövettani diagnózis az endothelsejt-degeneráció volt (130 esetben, 60,4%). 146 esetben (67,2%) korábban cadaver, 31 esetben (14,2%) multiorgan donor esetén került sor ismételt mutétre, 40 esetben (18,4%) nem állt rendelkezésre adat. Következtetés: Klinikánkon elsosorban cadaverbol származó donorok biztosítják a szaruhártya átültetésekhez szükséges szövetet. Cadaverbol vagy multiorgan donorból származó szaruhártyák esetén nem kerül gyakrabban sor rekeratoplasztikára. A szaruhártya-banki tevékenység további fejlesztésével növelheto a donorok túlélése hazánkban. Orv Hetil. 2021; 162(13): 488-496. INTRODUCTION: Corneal banking methods have been changing since the foundation of the first corneal bank in 1944. Corneal graft survival may be affected by several factors, among others the storage method, which may be short-, middle- and long-term storage. OBJECTIVE: To investigate corneal graft survival at the Department of Ophthalmology, Semmelweis University between 1 January 2008 and 31 December 2017, using cadaver and multiorgan donors for penetrating and lamellar keratoplasty, retrospectively. METHOD: Recipient sex, age, clinical diagnosis, date of surgery, histological examination results and origin of donors (cadaver or multiorgan donor) were recorded. Correlation between recipient age and time to repeat keratoplasty was also analyzed. RESULTS: There were 1451 keratoplasties in 1159 eyes (age 62.8 ± 18.5 years) of 1088 patients (44.6% male) using 938 (64.6%) cadaver and 262 (18.0%) multiorgan donors, data was not available in 251 (17.2%) cases. There was repeat keratoplasty in 217 patients (18.7% of first keratoplasties). The most common histological diagnosis was endothelial decompensation (130 cases, 60.4%) in these cases. In patients with a first repeat keratoplasty, in 146 cases (67.2%) the first donor originated from cadavers, in 31 cases (14.2%) from multiorgan donors and in 40 cases (18.4%) data were not available. CONCLUSION: Corneal donors mainly originate from cadavers at our Department. The necessity of repeat keratoplasties does not differ using cadaver or multiorgan donors. With further development of corneal banking, donor survival may be increased in Hungary. Orv Hetil. 2021; 162(13): 488-496.

Changing trends in penetrating keratoplasty indications at a tertiary eye care center in Budapest, Hungary between 2006 and 2017.

AIM: To analyze the changing trends in penetrating keratoplasty (PKP) indications. METHODS: This retrospective study included all patients with PKP between 2006 and 2017. Patients were classified using histological diagnoses. Our groups were as the following: pseudophakic or aphakic bullous keratopathy, regraft, acute necrotizing and ulcerative keratitis, keratoconus, Fuchs' dystrophy, corneal dystrophy other than Fuchs', corneal scar, other diagnoses and failed endothelial keratoplasty graft. Additionally, two different time-periods (2006-2012 and 2013-2017) were analysed. RESULTS: Totally 1721 histological analyses of 1214 patients were available for review. The diagnoses were pseudophakic or aphakic bullous keratopathy in 487 (28.3%), regraft in 443 (25.7%), acute necrotizing and ulcerative keratitis in 313 (18.2%), corneal scar in 153 (8.9%), keratoconus in 140 (8.1%). Fuchs' dystrophy in 61 (3.5%), corneal dystrophy other than Fuchs' in 46 (2.7%), other diagnoses in 44 (2.6%) and failed endothelial keratoplasty graft in 34 (2.0%) cases. From the first to the second analysed time-period, incidence of acute necrotizing and ulcerative keratitis, corneal scar, Fuchs' dystrophy increased (P≤0.032 for all) and incidence of keratoconus significantly decreased (P=0.015). CONCLUSION: Pseudophakic or aphakic bullous keratopathy is the leading indication for PKP, followed by regraft and acute necrotizing and ulcerative keratitis.

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.

Changing Trends in Penetrating Keratoplasty Indications between 2011 and 2018 - Histopathology of 2123 Corneal Buttons in a Single Center in Germany.

Purpose: To analyse the changing trends in penetrating keratoplasty indications between January 2011 and December 2018, at the Department of Ophthalmology, Saarland University Medical Center, Homburg/Saar, Germany. Patients and Methods: This is a retrospective review of 2123 corneal buttons of 1776 patients (1993 eyes, 56.0% males, age at the time of surgery 57.6 ± 18.7 years), who underwent penetrating keratoplasty (PKP) between January 2011 and December 2018. The classification was performed based on histological analysis and using the priority scheme of Brady et al., supplemented by a group of "failed endothelial keratoplasty grafts". Our groups were the following: pseudophakic or aphakic bullous keratopathy, regraft, failed endothelial keratoplasty graft, acute necrotizing and ulcerative keratitis, keratoconus, Fuchs' dystrophy, corneal dystrophy other than Fuchs', corneal scars and other diagnoses. Results: Between 2011 and 2018, keratoconus was the leading indication for PKP in 455 (21.5%) cases, followed by acute necrotizing and ulcerative keratitis in 384 (18.1%), regraft in 367 (17.3%), corneal scars in 350 (16.5%), pseudophakic or aphakic bullous keratopathy in 225 (10.6%), Fuchs' dystrophy in 194 (9.1%), other diagnoses in 64 (3.0%), corneal dystrophy other than Fuchs' in 52 (2.4%), and failed endothelial keratoplasty graft in 32 (1.5%) cases. Conclusions: With the introduction of posterior lamellar keratoplasty, keratoconus remains the leading PKP indication in our center with excimer laser-trephination on a routine basis. A trend towards increasing numbers can be observed regarding acute necrotizing and ulcerative keratitis patients and regrafts. However, the incidence of Fuchs' dystrophy decreased dramatically within PKP patients, with the introduction of posterior lamellar keratoplasty.

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.

[Bilateral idiopathic choroidal folds]. / Kétoldali idiopathiás choroidearedok.

Choroidal folds present as parallel bright and dark lines, which may be detected with funduscopy. Optical coherence tomography, red free fundus photography, autofluorescence and fluorescein angiography may be also helpful to establish the diagnosis. The authors present the case of a 70-year-old male who was evaluated because of a 1-month history of blurred vision on his right eye. Dilated fundus examination revealed choroidal folds in both eyes, which failed to affect visual acuity. No neurological pathologies were found. There was no change in the patient condition during a follow-up period of 6 months. The authors note that choroidal folds are often not recognized because they are usually asymptomatic. There are several possible causes which should be considered. The diagnosis of idiopathic choroidal folds is based on the exclusion of other pathologies. Observation of the patient's visual acuity and monitoring for fundus changes are needed.
