RESUMO
OBJECTIVE: We aimed to compare visual and anatomical outcome in vitrectomized and non-vitrectomized eyes treated with dexamethasone (DEX) implant due to diabetic macular oedema (DMO). DESIGN: Multicenter, retrospective, interventional study. PARTICIPANTS: 236 eyes from 234 patients with DMO with or without previous vitrectomy performed with follow-up of 12 months. METHODS: Records were reviewed for cases of DMO treated with DEX implant in vitrectomized and not vitrectomized eyes. Best corrected visual acuity (BCVA), central subfoveal thickness (CST), and intraocular pressure (IOP) were recorded at baseline and 12 months after treatment with DEX implants. Correlations between vitreous status and visual and anatomical outcome, as well as safety profile were analysed. MAIN OUTCOME MEASURES: BCVA and CST over follow-up period. SECONDARY OUTCOMES: cataract rate formation, intraocular pressure increase, number of implants needed. RESULTS: The non-vitrectomized group included 130 eyes (55.1%), the vitrectomized group included 106 eyes (44.9%). The groups were well balanced for age and gender (p = 0.540, and p = 0.053, respectively). Both groups showed statistically significant improvement in BCVA and CST (for all groups: p < 0.001). There was no significant difference between the groups in terms of change in vision (p = 0.89) and anatomy (p = 0.65). The mean number of DEX implants given during follow-up was 3.5 in both groups, and there was no significant difference between the groups (p = 0.81). CONCLUSION: We demonstrated similar anatomical and functional efficacy of DEX implant in non-vitrectomized and vitrectomized eyes. Its efficacy was not influenced by full vitrectomy for diabetic retinopathy complications. Safety profile was well balanced between groups.

PURPOSE: The purpose of this study was to report the 5-year outcomes of treatment-naive eyes with cystoid macular edema secondary to central retinal vein occlusion treated with intravitreal bevacizumab in routine clinical practice. METHODS: We conducted multicenter retrospective non-comparative case series of 102 eyes. The main outcome measured was the change in best-corrected visual acuity (BCVA) at 5 years. Secondary outcomes included the number of injections and the change in CMT at 5 years. RESULTS: At 5 years, the mean BCVA improved from 1.22 ± 0.58 (Snellen 20/428) at baseline to 1.00 ± 0.68 logMAR (Snellen 20/200; p < 0.0001). At 5 years, 48 (47%) eyes had a gain of ≥ 3 lines, 41 (40.2%) eyes remained within 3 lines and 13 (12.7%) eyes had a loss of ≥ 3 lines of BCVA. The CMT improved from 740 ± 243 to 322 ± 179 µm (p < 0.0001). At 5 years, 59 (57.8%) eyes had a completely dry SD-OCT. Patients received a total of 10.6 ± 6.1 (range 6-27) injections. Baseline BCVA (p < 0.0001) and the duration of symptoms prior to initial anti-VEGF injection (p = 0.0274) were the only predictive factors for BCVA at 5 years. CONCLUSIONS: After 5 years with an average of 10.6 injections, there was a mean gain of 0.22 logMAR. In addition, more eyes achieved a BCVA of ≥ 20/40, gained ≥ 3 lines and less patients had a BCVA ≤ 20/200. Eyes with a better baseline BCVA and a shorter duration of symptoms were more likely to achieve better BCVA at 5 years.

PURPOSE: To assess the risk for capsular rupture during routine phacoemulsification in patients with a history of anti-VEGF injections and other possible risk modifiers such as treatment patterns, type of anti-VEGF agent, and experience of the surgeon, among others. METHODS: This study reviewed the medical records of 11,129 patients from 7 different hospitals in 5 countries. The study included 939 patients that underwent routine phacoemulsification and had a history of anti-VEGF therapy. We excluded patients with known risk factors for capsular rupture, as well as patients with a history of other retinal procedures. The study extracted data regarding general demographics, the number of previous injections, type of anti-VEGF agent, details of cataract surgery, and anti-VEGF treatment patterns. RESULTS: Overall prevalence of posterior capsular rupture: 7.45% (95% CI: 5.9-9.32%). The mean number of injections per patient was 3.37 ± 2.8. More than 50% of the patients received their last anti-VEGF injection within three months before cataract surgery. The complication rate during intravitreal injections was 1.07%. In the univariate analysis, the experience of the cataract surgeon (inexperience surgeons; OR: 2.93) and the history of prior anti-VEGF therapy (OR: 1.77) were significant risk indicators for PCR (p < 0.05). However, after controlling for age in the multivariate analysis, the trend did not reach a statistical significance. CONCLUSION: The risk for capsular rupture is higher in patients with a history of intravitreal anti-VEGF injections.
RESUMO
Susac's syndrome (SS) is a relatively rare cause of multiple recurrent branch retinal arterial occlusions (BRAO). SS is frequently misdiagnosed and probably underdiagnosed. Ophthalmic manifestations may be the sole presenting sign of SS. Comprehensive literature review The typical triad of encephalopathy, sensorineural hearing loss and multiple recurrent BRAO is seldom seen at presentation in SS. The characteristic ophthalmological feature in SS is the presence of recurrent multiple BRAO in the absence of intraocular inflammation. Yellow to yellow-white, non-refractile or refractile retinal arterial wall plaques (Gass plaques) found at midarteriolar segments not associated to bifurcations are commonly found in SS. Because of its ability to capture more peripheral retinal area, ultrawide field fluorescein angiography (FA) has definite advantages over conventional FA and its use should be encouraged in patients suspected of having SS. Optical coherence tomography (OCT), particularly spectral domain OCT complements FA. Patients with BRAO and hearing loss that do not develop encephalopathy during the initial 2 years will most likely not develop encephalopathy. However, these patients will be prone to recurrent BRAO and hearing loss. Imunosuppression is the cornerstone of treatment but the best regimen still needs to be defined. A minority of patients with SS present with the typical triad. A high index of suspicion is needed to make the diagnosis promptly. Early diagnosis and treatment are important to delay disease progression and prevent blindness, deafness and dementia.

PURPOSE: The aim of this study was to evaluate the correlations between fundus autofluorescence and morphologic parameters as well as visual function in patients with diabetic macular oedema treated with intravitreal ziv-aflibercept. METHODS: A total of 34 eyes of 20 patients with untreated diabetic macular oedema received an intravitreal injection of ziv-aflibercept at baseline, and 1 and 2 months later. The baseline, 1-month, and two-month best corrected visual acuity determination, contrast sensitivity, spectral domain optical coherence tomography, mean central macular thickness, mean macular cube volume, mean macular cube average thickness, and fundus autofluorescence (decreased, normal, or increased; and single or multiple spots) were measured. Correlation analysis with a determination of Spearman's rank correlation coefficient, regression analysis, agreement between investigators, and Friedman's test were used for statistical analyses. RESULTS: A direct correlation was observed between baseline fundus autofluorescence and macular cube average thickness at 1 month (r = 0.51, p = 0.020) and between fundus autofluorescence at 1 month and baseline macular cube average thickness (r = 0.50, p = 0.021). Regression analysis showed a coefficient of determination of 0.29 (p = 0.016) between baseline fundus autofluorescence and macular cube average thickness at 1 month. CONCLUSION: In patients with diabetic macular oedema, the pretreatment baseline degree of foveal fundus autofluorescence might be helpful in predicting macular cube average thickness in patients undergoing treatment with intravitreal ziv-aflibercept in the short term.

PURPOSE: To compare the functional and anatomical outcomes of eyes with chronic central serous chorioretinopathy treated with yellow micropulse (MP) laser versus half-dose verteporfin photodynamic therapy (PDT). METHODS: This is a multicentre, retrospective comparative study of 92 eyes treated with yellow MP laser (duty cycle of 5%, zero spacing between spots, spot size varied from 100 to 200 µm, power varied from 320 to 660 mW, and the pulse burst duration was 200 ms) and 67 eyes treated with PDT (half-dose verteporfin (3 mg/m2) infused over 10 min), followed by laser activation for 83 s. Spot sizes varied from 400 to 2000 µm. RESULTS: In the MP group, at 12 months of follow-up, the mean best corrected visual acuity (BCVA) improved from the logarithm of the minimum angle of resolution (logMAR) of 0.41±0.27 at baseline to 0.21±0.26 (P<0.0001), 48.9% (45/92) of eyes had an improvement of ≥3 lines of BCVA from baseline, 48.9% (45/92) of eyes remained within 2 lines of baseline BCVA, and only 2.2% (2/92) of eyes lost ≥3 lines of BCVA from baseline. In the PDT group, at 12 months of follow-up, the mean BCVA changed from logMAR of 0.50±0.34 at baseline to 0.47±0.34 (P=0.89), 19% (13/67) of eyes had an improvement of ≥3 lines of BCVA from baseline, 73% (49/67) of eyes remained within 2 lines of baseline BCVA, and 7% (5/67) of eyes lost ≥3 lines of BCVA from baseline. There were no adverse events attributable to the yellow MP laser treatment. One eye in the PDT group developed choroidal neovascularisation, which was treated with three intravitreal bevacizumab injections. CONCLUSIONS: Both PDT and MP are effective in restoring the macular anatomy. In places where PDT is not available, yellow MP laser may be an adequate treatment alternative.

Purpose: This study was designed to evaluate the visual and anatomical outcomes after cataract surgery in diabetic patients with different intraoperative therapeutic strategies. Methods: The research design comprised of a multicentric, retrospective, interventional study conducted at 6 centers in Argentina, Brazil, Costa Rica, Puerto Rico, Spain, and Venezuela. We included 138 diabetic patients with at least 6-month follow-up following phacoemulsification and intraocular lens implantation. Best-corrected visual acuity (BCVA) and central subfield thickness were collected at baseline and at 1-, 2-, 3-, and 6-month follow-up. Of these, 42 cases were not treated with any intraoperative coadjuvant medication (Group 1), 59 patients received intraoperative bevacizumab (Group 2) and 37 patients received intraoperative triamcinolone (4 mg/0.1 ml) (Group 3). Results: The mean logMAR [± standard deviation (SD)] BCVA improved from 0.82 (± 0.43) at baseline, to 0.14 (± 0.23) at 6-month follow-up (p<0.001) in Group 1; from 0.80 (± 0.48) to 0.54 (± 0.45) (p<0.001) in Group 2; and from 1.0 (± 0.40) to 0.46 (± 0.34) (p<0.001) in Group 3. The mean central subfield thickness increased from 263.57 µm (± 35.7) at baseline to 274.57 µm (± 48.7) at 6-month follow-up (p=0.088) in Group 1; from 316.02 µm (± 100.4) to 339.56 µm (± 145.3) (p=0.184) in Group 2; and from 259.18 µm (± 97.9) to 282.21 µm (± 87.24) (p=0.044) in Group 3. Conclusion: Diabetic patients may significantly benefit from cataract surgery. This study provides evidence to support the use of intravitreal triamcinolone or bevacizumab at the time of cataract surgery in cases with pre-existent diabetic macular edema or moderate-severe non-proliferative diabetic retinopathy. .
Objetivo: Avaliar os resultados visuais e anatômicos após a cirurgia de catarata em pacientes diabéticos com estratégias terapêuticas intraoperatórias diferentes. Métodos: Estudo multicêntrico, retrospectivo, de intervenção realizado em 6 centros da Argentina, Brasil, Costa Rica, Porto Rico, Espanha e Venezuela. Foram incluídos 138 pacientes diabéticos com pelo menos 6 meses de seguimento após facoemulsificação com implante de lente intraocular. Acuidade visual melhor corrigida (BCVA) e a espessura subcampo central (CST ) foram coletadas no início e em 1, 2, 3 e 6 meses de seguimento. Destes, 42 casos não foram tratadas com qualquer co-adjuvante de medicamentos intra-operatório (Grupo 1), 59 pacientes receberam bevacizumab intraoperatório (Grupo 2), e 37 pacientes receberam triancinolona intraoperatória (4 mg/0,1 ml) (Grupo 3). Resultados: A média logMAR (± desvio-padrão [DP]) BCVA melhorou de 0,82 (± 0,43) no início do estudo, para 0,14 (± 0,23) aos 6 meses de seguimento (p<0,001) no Grupo 1; de 0,80 (± 0,48) para 0,54 (± 0,45) (p<0,001) no Grupo 2; e de 1,0 (± 0,40) para 0,46 (± 0,34) (p<0,001) no Grupo 3. A CST média aumentou de 263,57 µm (± 35,7) na linha de base para 274,57±48,7 µm em 6 meses acompanhamento (p=0,088) no Grupo 1; de 316,02 µm (± 100,4), para 339,56 µm (± 145,3) (p=0,184) no Grupo 2; e de 259,18 µm (± 97,9), para 282,21 µm (±87,24) (p=0,044) no grupo 3. Conclusões: Pacientes diabéticos podem se beneficiar significativamente da cirurgia de catarata. Este estudo parece fornecer evidências para apoiar o uso de triancinolona intravítrea ou bevacizumab no momento da cirurgia de catarata em casos com edema macular diabético preexistente (DME) ou retinopatia diabética não-proliferativa moderada a grave. .
