RESUMO
PURPOSE: Complicated retinal re-detachment with inferior proliferative vitreoretinopathy (PVR) remains a challenge. This study's aim was to compare vitrectomy with conventional silicon oil (CSO) combined with an encircling band (EB) and vitrectomy with heavy silicon oil (HSO) alone to treat retinal re-detachment through inferior PVR, where standard procedures have already failed. METHODS: A retrospective analysis was done on patients with inferior complex re-detachment with secondary PVR after primary surgery, who received pars plana vitrectomy (PPV) with CSO combined with EB (group 1) or PPV alone with HSO (group 2) between December 2006 and August 2017. The primary endpoint was retinal reattachment, and the secondary endpoint was visual acuity (VA) change and complications in both groups. RESULTS: This study included 119 eyes. Total single surgery anatomical success (SSAS) was 64%, with 80% (52/65) achieved in group 1 and 44.5% (24/54) in group 2 (p < 0.0001). The total final anatomical success (FAS) rate was 79% (94/119). In group 1, FAS was 91% (59/65) compared with 65% (35/54) in group 2 (p = 0.003). The pretreatment VA of group 1 had a median of 1.4 logMAR (95% CI 0.3-1.8), and group 2 showed a median of 1.4 logMAR (95% CI 0.2-1.8). The post-treatment decrease in group 1 was a median equal to - 0.6 versus - 0.1 for group 2 (p = 0.0001). Serious complications were similar in both groups. CONCLUSION: For complicated retinal re-detachment through inferior PVR, the combination of PPV with EB may lead to better anatomical (SSAS, FAS) and functional success compared with PPV alone with HSO.

PURPOSE: To present the long-term results of ab externo trabeculotomy in the management of glaucoma secondary to chronic uveitis. METHODS: In this retrospective single-centre case series, medical records of patients with glaucoma secondary to chronic uveitis, who underwent ab externo trabeculotomy, were evaluated. Two definitions of success were used: intraocular pressure (IOP) 6 ≤ IOP ≤ 21 mmHg (success 1) or 6 ≤ IOP ≤ 21 mmHg and at least 25 % reduction from baseline (success 2). Success was complete when no additional medication was required or qualified when additional medication or cycloablative procedures were required to achieve the specific IOP definition. RESULTS: Twenty-two eyes of 18 patients were included. After 3 years, median IOP decreased from 27 mmHg [range 17-43 mmHg, mean 27.5 mmHg, 95 % confidence interval of the mean (CI) 24.5-30.5 mmHg] to 15 mmHg (range 9-19 mmHg, mean 14.5 mmHg, CI 13-16.1 mmHg). Complete and qualified success 1 was 23 and 45 % after 3 years, respectively. For success 2, the rates were 23 and 32 %, respectively. Hyphema was the most common complication, which resolved completely within 1 month after surgery without further intervention. CONCLUSION: Trabeculotomy ab externo was moderately successful in glaucoma secondary to chronic uveitis after 3 years. No sight-threatening complications were observed during the follow-up period.

Purpose: To analyse single-operation anatomical success (SOAS) of primary rhegmatogenous retinal detachment (RRD) repair by junior vitreoretinal surgeons guided by preoperative individual case selection by an experienced mentor vitreoretinal surgeon. Methods: Retrospective, single institute, observational study, included all patients who underwent standard pars plana vitrectomy (PPV) or combined encircling band (CB) and PPV and gas tamponade in the treatment of RRD from November 2021 to December 2022 were included. Preoperative selection for the surgery decision, whether standard PPV or combined CB & PPV was undertaken through the senior surgeon; according to the location and extensions of the RRD, number of retinal tears (RT) and lens status. We excluded patients with tractional retinal detachment, RD with proliferative vitreoretinopathy stage C, giant tears, trauma, previous scleral buckle, schisis RD and RD requiring silicone oil. The primary outcome measure was to evaluate the single-operation anatomic success (SOAS). Secondary outcome measures evaluated whether there was a statistical significant difference between both procedures. Results: Eighty-two eyes were included in the study. Forty-five eyes were selected for combined CB&PPV and 37 eyes for standard PPV. SOAS was achieved in 40 eyes (88.8%) in combined group and 35 eyes (94.5%) in standard PPV group. There was no statistically significant difference in the success rate between both operations, p = 0.65. Conclusion: Structured preoperative selection of standardized surgical techniques according to the degree of complexity of RD together with close supervision enables junior vitreoretinal surgeons in training to achieve re-attachment rates of more than 80% with both types of surgeries.
RESUMO
BACKGROUND: This study was an analysis of fluorescein angiography (FAG) and indocyanine green angiography (ICGA) at a university eye hospital. The primary objective of the study was to analyze adverse drug reactions (ADRs) and their severity (mild, moderate, severe). The secondary objective was to investigate the indications of FAG and ICGA before and during the COVID-19 pandemic. METHODS: A retrospective analysis of all FAG and ICGA at the University Eye Hospital in Würzburg from January 2016 to the end of December 2021 was performed. The ADRs, gender, age, examination time points and indications were evaluated. The ADRs were classified into mild, moderate, and severe, following the definition of Kornblau et al. [1] RESULTS: A total of 4900 examinations from 4193 patients were analyzed. An FAG was performed slightly more frequently in men (54.8%) than in women (45.2%) and the mean age was 63.2⯱ 16.9 years (median: 65 years). The ADRs occurred in only 1.65% of all FAG, of which 1.27% were mild and 0.39% were moderate. No severe ADRs occurred. The most common ADR was nausea at 59.26%. No ADR occurred in ICGA. The annual number of FAGs averaged 816.7⯱ 91.1 and was relatively constant throughout the period except for a significantly reduced number in 2016 (compared with 2018, 2019, and 2021). The most common indication for FAG was venous retinal occlusion at 22.93% (Nâ¯= 774), showing a significant increase in 2021 compared to 2018-2020. An ICGA was performed in 4.18% of cases, with the most common indication being uveitis at 31.82% (Nâ¯= 63). CONCLUSION: Compared to other studies very few ADRs occurred and no life-threatening ADR occurred in any case. Venous retinal occlusions were very common indications for FAG, probably due to the frequent need for repeated examinations in this condition. Briefly, during the first lockdown (18 March-8 May 2020), a decrease in angiographies was observed, but over a longer period, no significant differences were seen compared with the prepandemic period.
RESUMO
Purpose: To evaluate the morphological macular changes and fluid dynamics under brolucizumab treatment in eyes refractory to previous anti-vascular endothelial growth factor (anti-VEGF) treatment for neovascular age-related macular degeneration (nAMD) compared with treatment-naive eyes. Methods: Retrospective study of all eyes treated with brolucizumab for nAMD between 2020 and 2021 with a fixed injection regimen and one year follow-up. Treatment-naive eyes (TN) were compared with eyes refractory to previous treatment with bevacizumab, ranibizumab, or aflibercept (RT). The primary outcome measure was change of best-corrected visual acuity (BCVA). Secondary outcome measures included foveal central thickness (FCT), presence of intra- or subretinal fluid (IRF, SRF) and presence of pigment epithelial detachment (PED) at any time point during treatment in both groups. Results: Seventeen TN eyes and 17 RT eyes were included. Mean BCVA and mean FCT in TN eyes had significantly improved after 3 months and continued to improve during treatment (p<0.05 and p=0.001, respectively). In RT eyes, mean BCVA did not change significantly while mean FCT had improved after 3 months of treatment and remained stable thereafter. SRF or PED were more frequent in RT eyes compared with TN eyes (p=0.003 and p=0.005, respectively). Conclusion: After 3 months of treatment, the BCVA increased significantly only in TN eyes, while the FCT was significantly reduced in both groups. IRF appears to be similarly seen in both groups after the loading phase; however, SRF and PED appear to be more frequent in the RT eyes compared with TN eyes.
RESUMO
PURPOSE: To evaluate retinal sensitivity using chromatic full-field stimulus thresholds (FST) in patients with treatment naive exudative age-related macular degeneration (e-ARMD) before and during the first intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment. PATIENTS AND METHODS: After general ophthalmological examinations to diagnose patients with e-ARMD the FST, the central foveal thickness (FCt) and the visual acuity were assessed in 20 eyes of 20 patients during this prospective study. Examinations were performed before and during the first treatment series with three intravitreal anti-VEGF injections. Normal values for FST were assessed in 19 eyes of 19 healthy subjects. Results were analyzed using Student's two-tailed t-test and Pearson's correlation coefficients between all functional parameters. RESULTS: At baseline and before the 1st intravitreal anti-VEGF treatment, a moderately significant negative correlation between VA and FCt was found in the e-ARMD group (p = 0.02, r = -0.45 and p = 0.03, r = -0.45), respectively. After the 2nd intravitreal anti-VEGF injection, no significant correlation between VA and FCt was found (p = 0.12). However, a significant correlation between FCt and blue FST was evident (p = 0.04, r = 0.4). After the 3rd intravitreal anti-VEGF treatment, there was no correlation evident between VA and FCt (p = 0.31) but a high significant correlation between FCt and FST using red (p = 0.01, r = 0.53), green (p = 0.002, r = 0.6) and blue light (p = 0.007, r = 0.66). CONCLUSION: During anti-VEGF treatment in patients with e-ARMD, the FST test showed higher significant correlations with the morphology measured by FCt, as it is the case for VA. These findings support that the FST test might serve as a valuable diagnostic tool for monitoring patients with e-ARMD and enhance functional assessment of retinal function under treatment with anti-VEGF.
RESUMO
AIM: To evaluate and correlate mean light sensitivity thresholds (MLST) in patients with congenital stationary night-blindness (CSNB) in comparison with healthy subjects using microperimetry (MP1). METHODS: Eleven patients with CSNB and 13 healthy subjects were compared. In all subjects, static threshold perimetry was performed using MP1 evaluating the central 6 mm of the retina. This central retinal area was divided into three rings through using the ETDRS grid algorithm with an innermost (1 mm), inner (3 mm) and outer ring (6 mm). The MLSTs were acquired in nine sectors of the ETDRS grid. A comparison of MLST was performed between both groups using a t-test (significance level p<0.005). RESULTS: A significant reduction of MLST in the fovea (innermost ring, 1 mm) was observed for patients with CSNB (7.2±3.90 dB) in comparison to healthy subjects (19.7±0.75; p<0.0001). Similarly, comparison of MLST in all other sectors (superior/inferior/temporal and nasal) within the inner and outer ring revealed a statistically significant reduction in patients with CSNB compared with healthy subjects (p<0.001). CONCLUSIONS: Examination of macular retinal sensitivity intensity using MP1 revealed for the first time a significant reduction of MLST within the central 6 mm of the retina in patients with CSNB compared with healthy subjects. This finding supports MP1 as an additional diagnostic tool when examining patients with retinal dysfunctions such as CSNB.

PURPOSE: To present the outcomes of Ahmed glaucoma valve implantation (AGV) in glaucoma secondary to Fuchs uveitis syndrome (FUS). METHODS: In this retrospective chart review, two definitions of success were used: 6 mmHg ≤intraocular pressure (IOP) ≤21 mmHg (success 1), and 6 mmHg ≤ IOP ≤21 mmHg and at least 25% reduction from baseline (success 2). Depending on the need of postoperative antiglaucoma medication, success was defined as either complete or qualified. RESULTS: In total, 17 eyes of 17 patients were included. Complete success rates (both definitions) were 23.5% (n = 17) after 1 year and 23% (n = 13) after 3 years. Qualified success rates (both definitions) were 58.3% (n = 17) after 1 and 38.4% (n = 13) after 3 years. Encapsulated bleb formation was the most common complication (47% of eyes). CONCLUSIONS: AGV was moderately successful in the management of glaucoma secondary to FUS. Success rates are improved by medications, needling, and cycloablative procedures.

PURPOSE: To report the outcomes of primary transconjunctival 23-gauge (23-G) vitrectomy in the diagnosis and treatment of presumed endogenous fungal endophthalmitis (EFE). METHODS: Retrospective analysis of patients with EFE who underwent diagnostic transconjunctival 23-G vitrectomy at a tertiary referral center. RESULTS: Nineteen eyes of 15 patients with EFE were included in the study. Four patients had bilateral and 11 patients unilateral disease. Sixteen eyes of 15 patients underwent 23-G vitrectomy to confirm the diagnosis using vitreous culture, polymerase chain reaction, and histopathologic examinations. All affected eyes were treated with intravitreal amphotericin B 5 µg/0.1 mL. Fourteen patients received additional systemic antifungal therapy. Diagnostic 23-G vitrectomy confirmed the diagnosis of EFE in 75% of the eyes (12/16). Candida was found to be a causative agent in 62.5% and Aspergillus in 12.5% of the eyes. Retinal detachment was the most common complication (42% of eyes). CONCLUSIONS: EFE can be easily confirmed using primary 23-G vitrectomy.

BACKGROUND: The aim of this study was to compare the long-term outcomes of ab externo trabeculotomy in primary open-angle glaucoma (POAG) and uveitic glaucoma (UG). DESIGN: This was a retrospective single-center case series study. PARTICIPANTS: Twenty eyes of 17 patients with POAG and 22 eyes of 18 patients with UG were included in this study. PATIENTS AND METHODS: The medical records of all consecutive patients with POAG and UG who underwent ab externo trabeculotomy since 2004 were reviewed. MAIN OUTCOME MEASURE: The main outcome measure was change in median intraocular pressure (IOP). Success was defined as IOP ≤21 mmHg (success 1) and IOP ≤21 mmHg and at least 25% reduction from baseline (success 2). RESULTS: In the POAG group, the median IOP decreased significantly from 22 mmHg (95% CI 21-25 mmHg; n=20) at baseline to 14 mmHg (95% CI 12-16; n=13) after 4 years, P<0.001. In the UG group, the median IOP decreased significantly from 27 mmHg (95% CI 24.5-30.5 mmHg; n=22) at baseline to 12 mmHg (95% CI 9-15 mmHg; n=15) after 4 years, P<0.001. Seven eyes in the UG group failed within the first year after surgery compared to none in the POAG group. Of these, four eyes had Fuchs' uveitis syndrome and two had granulomatous uveitis. No sight-threatening complications occurred in both POAG and UG groups. CONCLUSION: Ab externo trabeculotomy effectively reduced IOP in both UG and POAG groups. However, the success rates in the UG group were significantly lower due to the high failure rate in patients with Fuchs' uveitis syndrome and granulomatous uveitis. The procedure demonstrated a high safety profile in both UG and POAG patients.
