Outcome of Different Surgical Repair Techniques for Rhegmatogenous Retinal Detachment-A Health Economic Analysis in the Split-Dalmatia County, Croatia.

Purpose: The goal of this research is to investigate the characteristics and surgical techniques for repairing rhegmatogenous retinal detachment (RRD) and their influence on anatomical and functional success of the treatment with a special emphasis on the economic costs and outcome quality-adjusted life years (QALYs) of the procedures. Methods: This retrospective study analyzed data from 151 patients with RRD treated at the Department of Ophthalmology, Clinical Hospital Centre Split, Croatia, in a 3-year period, using one of three surgical techniques: pneumoretinopexy (PR), scleral buckling (SB) or pars plana vitrectomy (PPV), followed-up for at least 6 months. Demographic, pre- and post-operative ophthalmic exam parameters and surgical technique used were collected accordingly. Statistical analysis of the influence of the studied parameters upon anatomical and functional outcomes was performed, as well as health economic analysis on costs and derived utilities/QALYs of these surgical methods. Results: Of all patients, 130 (86%) were successfully operated on, and 21 patients (14%) required another surgical procedure. No statistically significant differences in the anatomical success between the 3 surgical techniques were found. However, the functional outcome (based on the final best corrected visual acuity (BCVA)) differed significantly. Despite improvement in the final BCVA, BCVA ≥ 0.5 was achieved in only 52 (34.4%) patients. The final BCVA showed significant association with the time elapsed from the onset of RRD to the surgical intervention, pre-operative BCVA, macular- and preoperative lens- status and type of surgery. The estimated diagnosis-related group (DRG) cost for day and inpatient surgery was based upon existing DRG cost for PPV, which for PR and SB was calculated accordingly. Based upon the success of the procedure and visual outcome, the overall calculated QALYs for PR and SB appeared to be similar, while the QALYs were lower for PPV. Conclusions: The success rate of treating RRD mostly depends on performing an early surgical procedure (especially in the case of attached macula), identification of all retina tears and, most importantly, choosing the appropriate surgical technique. Decisions on treatment for RRD should also be based upon cost-effective and QALYs-assessed procedures, especially in countries like Croatia, where limited healthcare resources exist. This study shows PR to be efficient and most cost-effective for RRD repairment in appropriate cases.

Outcomes in the Treatment of Subretinal Macular Hemorrhage Secondary to Age-Related Macular Degeneration: A Systematic Review.

Background: Subretinal macular hemorrhage (SRMH) secondary to age-related macular degeneration (AMD) is a relatively rare condition in ophthalmology characterized by blood collection between the neurosensory retina and the retinal pigment epithelium (RPE). Without prompt treatment, visual prognosis is poor. A plethora of treatment approaches have been tried over the past years ranging from intravitreal anti-vascular endothelial growth factor (anti-VEGF) monotherapy to direct subretinal surgery, with no conclusive superiority of one over the other. Materials and Methods: We conducted a systematic review of the outcomes and treatment modalities of SRMH from inception to 14 June 2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). The level of evidence was assessed for all included articles according to the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Results: A total of 2745 articles were initially extracted, out of which 1654 articles were obtained after duplicates were removed and their abstracts screened. A total of 155 articles were included for full-text review. Finally, 81 articles remained that fulfilled the inclusion criteria. Conclusions: Even though there are solid results supporting a variety of treatments for SRMH, the best treatment modality has still not been conclusively demonstrated and further research is needed.

Early versus Late Pars Plana Vitrectomy in Vitreous Hemorrhage: A Systematic Review.

Background: Vitreous hemorrhage (VH) is a common vitreoretinal condition causing impairment of vision due to various etiologies. No consensus exists on the best timing for performing pars plana vitrectomy (PPV) in fundus-obscuring VH. Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, we conducted a systematic review of the timing of PPV in VH. We assessed the strength of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for all the included publications, in accordance with the 2011 Oxford Centre for Evidence-Based Medicine (OCEBM) recommendations. Results: A total of 1731 articles were identified. Following the removal of duplicates and screening of abstracts, 1203 articles remained. Subsequently, a comprehensive full-text review of 30 articles was conducted. Ultimately, 18 articles met the predefined inclusion criteria. Conclusions: Despite the small number of studies on the timing of treatment for VH, the advantage of early over late PPV seems to be a reasonable approach in selected cases, and it might be considered modern standard care.

Macular hole Delphi consensus statement (MHOST).

PURPOSE: To derive a Delphi method-based consensus for the surgical management of Full Thickness Macular Hole (FTMH) and Lamellar Macular Hole (LMH). METHODS: 37 expert VR surgeons from 21 mainly European countries participated in Delphi method-based questionnaire for diagnosis and treatment of FTMHs and LMHs. RESULTS: A total of 36 items were rated in round 1 by 37 participants, of which 10 items achieved consensus: intraoperative verification of PVD; clinical superiority of OCT-based FTMH classification; practical ineffectiveness of ocriplasmin; circular 360° ILM peeling for small macular holes; use of regular surgical technique for the size of the hole in concomitant retinal detachment; performing complete vitrectomy; SF6 gas as preferred tamponade; cataract surgery if crystalline lens is mildly/moderately opaque; removal of both ILM and LHEP in LMH surgery. In round 2, 18 items with moderate consensus (45-70% agreement) in round 1 were rated by 35 participants. Final consensus was reached in 35% of questions related to both diagnosis and surgical procedures. CONCLUSIONS: This Delphi study provides valuable information about the consensus/disagreement on different scenarios encountered during FTMH and LMH management as a guide tosurgical decision-making. High rate of disagreement and/or variable approaches still exist for treating such relatively common conditions.

Pseudoexfoliative Syndrome in Cataract Surgery-A Quality Register Study and Health Economic Analysis in the Split-Dalmatia County, Croatia.

PURPOSE: To investigate the impact of pseudoexfoliation (PEX) syndrome on intraoperative phacoemulsification (PHACO) parameters and assess the economic cost of PHACO surgery for cataracts in patients with and without PEX syndrome. METHODS: This was a retrospective quality register study on 5889 patients (6236 eyes) who underwent PHACO cataract surgery in the Eye Clinic, Clinical Hospital Centre Split, Croatia, over a 7-year period (May 2015 to December 2022), in accordance with the Guidelines of the Helsinki Declaration and approval from the Research Ethics Committee of the University Hospital Centre Split, Croatia. Inclusion criteria were patients with either presenile or senile cataract or cataract related to PEX syndrome who undertook PHACO procedure by the same experienced surgeon using the same PHACO device (Infiniti Vision System, Alcon Laboratories, Inc., Fort Worth, TX, USA). Eyes were categorized according to PEX presence- (PEX group) or absence (Group without PEX). The following recorded data about intraoperative PHACO parameters were collected: Cumulative Dissipated Energy (CDE), Ultrasound total time, PHACO time, torsional time, aspiration time, estimated fluid used, and duration of the surgical procedure. In the economic analysis, all PHACO parameters were considered, with a specific focus on the duration of the surgical procedure, costs associated with additional medical materials and devices, complications during surgery, and surgery procedure Diagnosis-Related Group (DRG) codes. RESULTS: A total of 4535 cases were eligible for inclusion in the study, 278 (6.13%) were diagnosed with PEX and 4257 (93.87%) had no PEX. Significantly higher PHACO parameters were observed in the PEX group. Similarly, a statistically significant increase in the values of all PHACO parameters was observed with the increase in nuclear lens density. Intraoperative complications were more frequent in the PEX group. Zonular weakness requiring the use of a capsular tension ring (CTR) and posterior capsular rupture occurred 30 and 13 times more often, respectively, in the PEX group. The expected cost of the PHACO procedure was found to be 1.4 times higher in patients with PEX, compared to those without PEX, for all types of nuclear cataract. CONCLUSIONS: All PHACO parameters are significantly higher in patients with PEX. The costs associated with PHACO surgery for cataracts are greater for patients with PEX and are not covered by the present DRG codes, which highlights the need to accordingly adjust the DRGs for PHACO procedures in PEX patients, in order to maintain the quality of healthcare provided for these vulnerable patients.

Internal Limiting Membrane Peeling and Gas Tamponade For Full-Thickness Macular Holes of Different Etiology - Is It Still Relevant?

Background: Despite the abundance of novel surgical approaches proposed for full thickness macular hole (FTMH) treatment, the choice of the optimal technique remains debatable Vitrectomy with «classic¼ internal limiting membrane peeling and gas tamponade remains the standard of FTMH surgery in many cases, but there are still very limited recent publications on the outcomes of such surgery. Purpose: To investigate the anatomical and functional result and to analyze the significance of outcome-related risk factors of the classic 25-gauge pars plana vitrectomy (PPV) with ILM peeling and gas tamponade (GT) for treatment of FTMH of different etiology. Patients and methods: Thirty-eight eyes of thirty-seven patients with FTMH who underwent 25-gauge PPV, ILM peeling and GT were recruited for this retrospective, consecutive, interventional study. Four eyes with persistent holes underwent a re-operation. Outcome-related factors were discussed. Results: The primary closure rate was 89.5% (34/38). All eyes that underwent the repeated surgery (4 cases) obtained final closure. A hole size of >500 µm has a statistically significant effect on the primary macular hole closure (F = 0.048; φ = 0.38; p ˂ 0.05). In the general group (N = 38), the duration of symptoms directly correlated with age (ρ = 0.34; p = 0.04), size of the hole (ρ = 0.66; p ˂ 0.001) and BCVA before surgery (ρ = 0.59; p ˂ 0.001), after 1 month (ρ = 0.36; p = 0.03), and after 3 months (ρ = 0.35; p = 0.03). Preoperative BCVA was better in initially closed cases (Group 1) (U = 26.0; p = 0.05). In the Group 2 with primary unclosed holes, 75% of the eyes (3/4) had an axial length (AL) >26 mm, while in Group 1 such eyes were 12.5 times less (2/34) 5.9% (F = 0.004; φ = 0.63; р ˂ 0.01). The ELM recovery rate at 3 months was 92% (35/38 eyes) and the restoration of EZ at 3 months was 47% (18/38 eyes). Best-corrected visual acuity of all individuals improved significantly from 0.72 ± 0.35 (logMAR) (Me = 0.7; IQR: 0.5-0.8) to 0.25±0.14 (logMAR) (Me = 0.2; IQR: 0.2 - 0.3) at 1 month and 0.17 ± 0.13 (logMAR) (Me = 0.2; IQR: 0.1 - 0.2) at 3 months after surgery (P = 0.0001). Conclusion: 25G PPV with ILM and GT for FTMH of different etiology provide satisfactory morphologic and functional outcomes. Elongated AL, large diameter of MH and long duration of symptoms are the risk factors for initial closure. Proper second surgery can obtain satisfactory outcomes for persistent holes.

Simple new technique for macular pucker peel without forceps.

Purpose: This study aimed to describe the effectiveness and evaluate the anatomical and functional results of surgery for macular pucker (MP) peel using a 25-gauge pars plana vitrectomy (PPV) cutter without forceps. Methods: This study assessed a prospective consecutive case series of 14 eyes of 14 patients who underwent 25-gauge PPV for MP. The surgical procedure was performed using the new peeling technique. The edge of the membrane was engaged at the opening of the cutter by gradually increasing the vacuum. The peeling process was finished by holding a stable vacuum or regrasping the membrane in the same manner. Results: The study included six women and eight men patients with a mean age of 72.3 (range 59-84) years. MP peel was achieved in all cases without the need for microforceps. Patients were followed for at least 6 months. Visual acuity and retinal thickness were obtained 6 months after the surgery. Best corrected visual acuity improved from a mean pre-operative 0.6 on a logMAR scale to post-operative 0.23 (P < 0.001). Mean pre-operative Central Retinal Thickness was significantly reduced from 489.7 to 377.6 µm post-operatively (P < 0.001). There were no intra- or post-operative complications. Conclusion: MP peel with a 25-gauge vitrectomy probe could be an alternative simple and safe technique. The technique does not require extra instrumentation. It results in anatomic and functional improvement in all cases.

Outcomes from the Retrospective Multicenter Cross-Sectional Study on Lamellar Macular Hole Surgery.

Purpose: To analyze the functional and anatomical parameters of lamellar macular hole (LMH) surgery with internal limiting membrane peeling and determine which surgical technique provides the best visual outcome. Methods: This is a retrospective multicenter cross-sectional study on patients who underwent pars plana vitrectomy (PPV) for LMH with or without combined phaco-vitrectomy, as well as gas-, air- or BSS-tamponade. Pre- and postoperative examination included best corrected visual acuity (BCVA) measurements for functional comparison and optical coherence tomography (OCT) scans to determine the contributing anatomical parameters. Results: A total of 66 consecutive patients were included (age: 71.79 ± 8.52 years), of which 47 (71.2%) were diagnosed as tractional type LMH, and 19 patients (28.8%) as degenerative type. An epiretinal membrane (ERM) was present in 63 of the patients (95.5%), LMH-associated epiretinal proliferation (LHEP) was present in 19 patients (28.8%), and 16 patients (24.2%) had concomitant ERM and LHEP. In the group of tractional LMH, the mean central foveal thickness (CFT) was 81.1% thicker (P < 0.05) than in the degenerative group. Thirty-one patients (47.0%) underwent a combined phaco-vitrectomy procedure, while the rest underwent 23G, 25G or 27G PPV. Seventeen of the 66 patients received gas-tamponade (25.7%)-either SF6 or C3F8, 26 received air-tamponade (39.4%), while the remaining 23 patients received balanced salt solution (BSS)-tamponade (34.9%) during vitrectomy. The total BCVA showed significant improvement postoperatively (p < 0.001) and accordingly in the following groups: tractional LMH type (p < 0.001), degenerative type (p < 0.001), simple PPV (p < 0.001), phaco-vitrectomy (p < 0.001), BSS injection (p < 0.01), gas-tamponade (p < 0.05). None of the patients included in the study developed a full thickness macular hole postoperatively. Conclusion: PPV provided a high success rate and functional improvement for treating LMH for both tractional and degenerative types, as well as combined phaco-vitrectomy treatment when cataract was present.

Healthcare expenditure of intravitreal anti-vascular endothelial growth factor inhibitors compared with dexamethasone implant for diabetic macular oedema.

PURPOSE: The aim of this study was to estimate the 1-year costs associated with treating diabetic macular oedema (DME) patients using current intravitreal anti-vascular endothelial growth factor (anti-VEGF) biologics compared with the dexamethasone implant. METHODS: We conducted a descriptive cost-evaluation analysis using data from Oslo University Hospital and literature to compare three different intravitreal drugs for DME: bevacizumab, aflibercept and dexamethasone. Stratification of patients into 'Naive' or 'Switch' group was based on treatment history. We estimated the costs from healthcare and 'extended' healthcare perspectives. Sensitivity analysis evaluated the impact of various parameters. RESULTS: The average injections per patient per year for the Naive group (bevacizumab), Switch group (aflibercept) and dexamethasone were 9.5, 9.1 and 3.0 respectively. From a healthcare perspective, the 1-year costs for the Naive group were 15% lower (bevacizumab, €3619), and for the Switch group, 23% higher (aflibercept, €5226) compared with dexamethasone (€4252). The 'extended' healthcare perspective showed the cost per patient per year for bevacizumab remained nominally lower in the Naive group, while dexamethasone remained lower for the Switch group (€5116 for dexamethasone, compared to €4987 for bevacizumab and €6537 for aflibercept). CONCLUSIONS: From a primary healthcare perspective, the dexamethasone as a first-line DME treatment may increase economic costs in settings where bevacizumab is used off-label. Treating resistant DMEwith dexamethasone may reduce the costs and treatment burden compared with switching to aflibercept.

Xerostomia and hyposalivation among a 65-yr-old population living in Oslo, Norway.

This study aimed to describe the prevalence and associated factors for xerostomia and hyposalivation in a young-elderly population. A random sample of 460 65-yr-old people living in Oslo, Norway, answered a questionnaire and underwent a clinical examination (237 men and 223 women; response rate 58%). Ten percent of respondents reported xerostomia. The median Summated Xerostomia Index was 6 (interquartile range [IQR]: 5-7) and the median Clinical Oral Dryness Score was 2 (IQR: 1-3). The median unstimulated whole saliva (UWS) secretion rate was 0.34 (IQR: 0.20-0.53) mL min-1 and the median stimulated whole saliva (SWS) secretion rate was 1.74 (IQR: 1.24-2.38) mL min-1 . In 8% of the study participants the UWS secretion rate was ≤0.1 mL min-1 and in 4% the SWS secretion rate was ≤0.7 mL min-1 . Three percent of the study participants had both xerostomia and hyposalivation with respect to UWS. Xerostomia was significantly associated with medication use, having rheumatic disease, and having received radiation therapy to the head/neck region. Hyposalivation with respect to UWS and SWS was significantly associated with medication use and type II diabetes. Even though xerostomia and hyposalivation were not prevalent conditions in this population, clinicians should be especially aware of the salivary conditions in patients taking four or more medications, patients diagnosed with type II diabetes, and those who have undergone radiation therapy to the head/neck region.

Trends and clinicopathological characteristics of oral squamous cell carcinomas reported at a tertiary cancer hospital in Nepal during 1999 to 2009.

OBJECTIVE: Reliable data describing the trends and clinicopathological characteristics of oral squamous cell carcinoma (OSCC) in the Nepalese population are very limited. The current study aimed to examine the demographics, trend, and clinicopathological characteristics of OSCC reported to the main referral/tertiary cancer hospital, the B.P. Koirala Memorial Cancer Hospital (BPKMCH) in Nepal for a period of 11 years (1999-2009). MATERIAL AND METHODS: This is a cross-sectional study. Data were retrieved retrospectively from hospital register maintained in the Department of Ear, Nose, Throat at BPKMCH, categorized into demographic and clinicopathological variables and SPSS (V25) was used for the analysis. RESULTS: In a period of 11 years, 3,452 cases of head and neck cancer were registered at the Department of Ear, Nose, Throat, BPKMCH. Out of 1,111 oral cancer cases, 1,081 (97.3%) were OSCC. A trend for increasing number of OSCCs presenting to BPKMCH was observed during that period. OSCC was found to be more common among males (73.0%), Brahmin/Chhetri ethnic groups (33.0%), in age group of 51-60 years (31.9%), and in Terai region (62.0%). Tongue (42.8%) was the most common site, followed by buccal mucosa (27.2%). Nevertheless, when stratified with respect to the geographical location and ethnicity, buccal mucosa was the most common site for OSCC in Terai region (63.9%, p = .002) and in Madhesi ethnic group (34.2%, p < .001). Majority of OSCC cases were diagnosed at advanced stage (49.7%, Stage IV) and received a combination therapy (42.0%). CONCLUSIONS: Hospital-based records can provide valuable information on disease characteristics in countries like Nepal. This study revealed that the clinicopathological characteristics of OSCC in Nepal follow the global trend. Nevertheless, relationship between specific intraoral sites for OSCC with geographic location and ethnic groups is an interesting observation and requires further population-based studies to clarify these findings.

Cost-effectiveness of the triple procedure - phacovitrectomy with posterior capsulotomy compared to phacovitrectomy and sequential procedures.

PURPOSE: To evaluate the cost-effectiveness of the triple procedure (phacovitrectomy + posterior capsulotomy, PhacoPPVc) compared to the double- (phacovitrectomy, PhacoPPV) or single sequential procedures. METHODS: Prospective study on 31 eyes from 31 patients (mean age: 72.1 ± 9.1 years; 55% females) was performed with a preoperative decision to undergo only pars plana vitrectomy (PPV) (26%) or PhacoPPV (74%) and/or posterior capsulotomy based upon presence or absence of lens opacification or pseudophakia. Time during and between surgeries, surgical procedure codes, medical and transport costs, outcome and likelihood of complications after surgery were all included in the analysis. Societal perspectives and visual acuity were considered as measures of quality of adjusted life years (QALYs). RESULTS: About 23 eyes underwent triple procedure and eight eyes underwent vitrectomy only (mean surgery times: 35.9 and 24.0 min, respectively). Posterior capsulotomy took on average 30 s, while preparation and cataract procedure took 13.0 min. The patients travelled on average 80km (average cost: $280.12) to the surgery unit. The average reimbursement fee for the day procedures ranged between $174.17 (YAG capsulotomy; Diagnosis Related Group (DRG): 0.034), $1045.48 (Phaco + intraocular lens (IOL); DRG: 0.204) and $1701.32 (PPV; DRG: 0.332). The combined procedures excluded lens and laser reimbursements, while the calculated reimbursements for the double/triple procedures were $2713.08/$2901.45, respectively, without significant loss of QALYs. PhacoPPVc was found to be unequivocally cost-effective, while PhacoPPV remained cost saving compared to sequential procedures. CONCLUSION: This study confirms that the triple procedure has benefits to the patients, health institution and surgeon. For patients, it saves them travel and healing time; for health institution, it justifies the calculated higher costs and need for higher reimbursement for the double/triple procedures, which are cost saving.

Outcomes of Vitrectomy for Long-Duration Macular Hole.

: The present study investigated the functional and anatomical outcomes of idiopathic chronic macular hole (MH) surgery with different surgical approaches related to the chronicity and diameter of the MH. A comparative retrospective study between three groups of patients who underwent vitrectomy for long-duration MH (mean: 13.5 months) was conducted. In the first group of patients (G1 or IP), the internal limiting membrane (ILM) was systematically peeled; in the second group (G2 or IPEP), the ILM and epiretinal membrane (ERM) were peeled; and in the third group (G3 or IF), patients underwent inverted ILM flap technique surgery. Pre- and post-operative best corrected visual acuities (pre- and post-op BCVA) were studied. Macular optical coherence tomography (OCT) scans were performed to measure the MH minimum and maximum diameter pre-operatively, as well as to confirm its post-op closure and evaluate the integrity of the ellipsoid zone (EZ). Fifty eyes of 48 patients (33 female and 15 male) were retrospectively evaluated. MH closure rate was 100% in IP group, 66.7% in IPEP, and 95.2% in IF group. All three groups had a statistically significant improvement of BCVA. EZ post-op was restored in 88.2% of the cases from G1, 41.6% from G2, and 23.8% from G3. No statistically significant relationship between the smaller or larger MH diameter and the visual acuity improvement was found. Patients with chronic MH and ERM have worse functional and anatomical outcomes after surgery. Treatment of chronic MHs without ERM results in a better closure rate with either an inverted ILM flap approach or systematic ILM peel.

Macular Hole Surgery Using Gas Tamponade-An Outcome from the Oslo Retrospective Cross-Sectional Study.

Purpose: The study aims to determine the anatomical success and functional outcome of pars plana vitrectomy (PPV) for macular holes (MH) performed at a single study center using a consistent procedure of internal limiting membrane (ILM) peeling, SF6 tamponade and 3 days face-down positioning. Methods: A retrospective cross-sectional study involving eyes with MHs which underwent 23- or 25-gauge PPV with or without phacoemulsification and all undergoing a 20% SF6 gas tamponade, follow-up to 6 months postoperatively were included at the Department of Ophthalmology, Oslo University Hospital and University of Oslo, Oslo, Norway (12-month study period between 1 January and 31 December 2015) Pre- and post-operative Best-Corrected Visual Acuity (BCVA) assessment, comprehensive eye examination and intraocular pressure (IOP) measurement. as well as Optical Coherence Tomography to determine the diameter of the MH and its closure were all carried out. Results: 198 consecutive eyes operated for MH (age: 69.4 ± 7.6 years; 1.6:1 female:male ratio) were included; 35.7%/48.6% had symptoms from 3-6/6-48 months; 5.1% had high-grade myopia, 21.5% focal VMT <1500 µm with or without epiretinal membrane (ERM), and 74.0%/26.0% had phakic/pseudophakic status. Primary closure of the MH occurred in 93.3% of the patients. Lens status and length of symptoms showed no significant correlation with closure of the MH. The pre-operative logMAR visual acuity: 0.8 ± 0.3 (median: 0.7; interquartile range (IQR): 0.5-0.8; range: 0.3-1.7), improved significantly post-operatively: 0.4 ± 0.3 (median: 0.3; interquartile range (IQR): 0.1-0.5; range: -0.02-1.2). BCVA improvement of <0.2, 0.2-0.4 and >0.4 was present in 28.3%, 27.3% and 44.4% of the treated patients. No significant median differences could be detected between the duration of the pre-operative symptoms and the pre-/post-operative visual acuity. Increased IOP was measured in 2.6% of the cases day after surgery. Conclusions: Our study found visual outcome not to be dependent upon the length of symptoms in MH patients treated by PPV all undergoing ILM peeling, SF6 tamponade and face-down positioning. The large diameter MH was not a limiting factor to achieve improved post-operative BCVA.

Effect of NSAIDs on Pupil Diameter and Expression of Aqueous Humor Cytokines in FLACS Versus Conventional Phacoemulsification.

PURPOSE: To compare the concentrations of interleukin (IL) (IL-1b, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70), interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and TNF-ß in the aqueous humor of patients undergoing femtosecond laser-assisted cataract surgery (FLACS) and corneal mechanical paracentesis treated with two different topical nonsteroidal anti-inflammatory drugs (NSAIDs): bromfenac and indomethacin. METHODS: In this prospective, randomized controlled, single-center study, aqueous humor samples were obtained immediately after performing the femtosecond laser procedure or at the start of conventional phacoemulsification. Preoperatively, the FLACS groups were administered (once daily and four times daily, respectively) either topical bromfenac 0.09% (12 eyes) or indomethacin 0.1% (12 eyes). The corneal paracentesis bromfenac and indomethacin groups received the same regimen of instillation of NSAIDs, respectively. Quantitative analysis of the expressed cytokines in the aqueous humor was performed using FlowCytomix FC 500 Pro 3.0 Software (Bender MedSystems GmbH, Vienna, Austria). RESULTS: The intraoperative pupil diameter was correlated with the expression of IL-6 after the femtosecond laser procedure in the FLACS indomethacin group (r = -0.53; P = .07). A significant difference in mean pupillary size was detected between the FLACS bromfenac and indomethacin groups at the aspiration/irrigation time point (0.53 ± 0.26 mm) and at the end of surgery (0.68 ± 0.37 mm). Progressive pupillary constriction was observed in the indomethacin and bromfenac groups. CONCLUSIONS: A smaller expression of IL-6 to the overall cytokine network value was observed in cases receiving preoperative bromfenac 0.09%, explaining improved maintenance of intraoperative mydriasis.

Anatomical success rate of pars plana vitrectomy for treatment of complex rhegmatogenous retinal detachment.

BACKGROUND: Pars plana vitrectomy (PPV) is preferred surgical procedure for the management of complex rhegmatogenous retinal detachment (RRD). The purpose of this study was to evaluate the anatomical results of primary PPV for the treatment of primary complex RRD and to determine the influence of lens status, tamponading agent, preoperative proliferative vitreoretinopathy (PVR) and axial length (AL) of the eye upon the anatomical outcome. METHODS: A retrospective consecutive chart analysis was performed on 117 eyes from 117 patients with complex RRD managed with PPV. Fifty-nine eyes were phakic and 58 pseudophakic eyes. All patients had a minimum follow-up period of 12 months. Eyes were classified into groups using independent variables (first classification based upon lens status and tamponade used, second classification based upon lens and PVR status and third classification based upon AL of the eye). The groups were compared for anatomical outcomes (dependent variables) using nonparametric- or, in case of normally distributed data, parametric- statistical tests. RESULTS: Retinal reattachment rate in phakic eyes was 94.9% compared to 93.1% in pseudophakic, with no statistically significant difference between the two. The overall retinal reattachment rate with single surgery was 94.0%. Final reattachment rate was 97.4%. In case of established PVR ≥ C1, the reattachment rate was not statistically different (92.6%) from eyes with no PVR (91.1%) irrespective of lens status. A statistically significant difference was found between redetachment rates only between phakic eyes with gas tamponade compared to silicon oil (SO) (p = 0.001). Reattachment rate proved to be similar in both AL groups (≤24 mm and > 24 mm). CONCLUSIONS: High anatomical success rate of primary vitrectomy for complex RRD with either gas or SO tamponade was achieved in phakic as well as pseudophakic eyes irrespective of AL of the eye.

Diabetic Retinopathy Screening Using Telemedicine Tools: Pilot Study in Hungary.

Introduction. Diabetic retinopathy (DR) is a sight-threatening complication of diabetes. Telemedicine tools can prevent blindness. We aimed to investigate the patients' satisfaction when using such tools (fundus camera examination) and the effect of demographic and socioeconomic factors on participation in screening. Methods. Pilot study involving fundus camera screening and self-administered questionnaire on participants' experience during fundus examination (comfort, reliability, and future interest in participation), as well as demographic and socioeconomic factors was performed on 89 patients with known diabetes in Csongrád County, a southeastern region of Hungary. Results. Thirty percent of the patients had never participated in any ophthalmological screening, while 25.7% had DR of some grade based upon a standard fundus camera examination and UK-based DR grading protocol (Spectra™ software). Large majority of the patients were satisfied with the screening and found it reliable and acceptable to undertake examination under pupil dilation; 67.3% were willing to undergo nonmydriatic fundus camera examination again. There was a statistically significant relationship between economic activity, education and marital status, and future interest in participation. Discussion. Participants found digital retinal screening to be reliable and satisfactory. Telemedicine can be a strong tool, supporting eye care professionals and allowing for faster and more comfortable DR screening.

Selenium levels in men with liver disease in Hungary.

PROJECT: We studied the relationship between selenium (Se) levels and chronic liver disease (CLD) severity and the association between socioeconomic and lifestyle factors and serum Se levels. PROCEDURE: We performed a case-control study in Hungarian men, examining 281 patients with CLD and 778 controls. Liver function was evaluated using biochemical markers, and liver disease was verified with physical examination and blood tests. Linear regression analysis was performed to study the association of serum Se level with biochemical markers in cases and controls. In control participants we examined the relationship between Se levels and age, financial status, education, alcohol consumption, cigarette smoking, type of fat used for cooking and body mass index. RESULTS: Serum Se levels were lower in cases (median 0.87 µmol/L (IQR: 0.77-1.03)) than in controls (median 1.08 µmol/L (IQR: 0.97-1.19)). In controls, increases in bilirubin and glutamic-oxaloacetic transaminase (GOT) were associated with decreases in Se levels. In patients with CLD, a statistically significant relationship was found between serum Se and the GOT/GPT ratio, albumin and bilirubin. Younger, better-educated controls had significantly higher, and regular smokers and heavy drinkers had significantly lower Se levels. The use of vegetable oil/fat was also associated with higher Se levels. Se level was associated with the severity of liver injury in people even in patients who did not exhibit signs and symptoms of CLD. CONCLUSIONS: Serum Se level is strongly associated with the severity of liver damage in people with CLD from the early stage on.
