RESUMO
PURPOSE: This study describes presenting clinical features and surgical techniques associated with successful repair of pediatric rhegmatogenous retinal detachment (RRD). METHODS: This is a retrospective case series which involved 242 cases younger than 18 years with new-onset RRD with descriptive statistics for the full group. Further exclusion established 168 cases that underwent surgery with minimum 3-month follow-up. Comparison of features associated with successful outcomes was analyzed using Chi-squared tests, logistic regression and univariate generalized equation models. RESULTS: We measured proportion of patients with BCVA ≤ 1.0 logMAR and/or an increase in final BCVA of 0.3 logMAR with respect to baseline and complete reattachment at final visit; 104 eyes (62%) achieved total reattachment, and 91 eyes (54%) achieved visual success. Absence of macular involvement, subtotal RRD and older age group (13-18) were associated with both success measures. There were higher visual and anatomic success rates with primary scleral buckling (SB, 66% and 79%; OR 9.26 and 11.09) and combined SB plus pars plana vitrectomy (PPV, 54% and 58%; OR 5.67 and 3.94) compared with PPV alone (26% and 17%). CONCLUSION: A majority of patients achieved anatomical success with repair. Trauma and myopia were the most common etiologic associations, with myopic cases having better outcomes. Success was more likely in patients with subtotal RRD or uninvolved macula at presentation; previous intraocular surgery was a risk factor for failure. Younger patients had a higher likelihood of worse outcomes. Initial PPV showed a lower rate of success than either SB or combined SB/PPV.

AIMS: During diabetic macular oedema (DME), a spectrum of capillary abnormalities is commonly observed, ranging from microaneurysms to large microvascular abnormalities. Clinical evidence suggests that targeted photocoagulation of large microvascular abnormalities may be beneficial, but their detection is not done in a routine fashion. It was reported that they are better identified by indocyanine green angiography (ICGA) than by fluorescein angiography. Here, we investigated the prevalence and ICGA and optical coherence tomography (OCT) features of retinal microvascular abnormalities in a group of patients with DME. METHODS: Observational study. The fundus photographs, ICGA and structural and angiographic OCT charts of 35 eyes from 25 consecutive patients with DME were reviewed. RESULTS: 22 eyes (63%) had at least one focal area of microvascular abnormalities showing prolonged indocyanine green (ICG) staining (ie, beyond 10 mins after injection). In particular, all eyes (n=9) with circinate hard exudates showed foci of late ICG staining. These areas were either isolated globular capillary ecstasies or a cluster of ill-defined capillary abnormalities. They were located at a median distance of 2708 µm from the fovea (range: 1064-4583 µm). Their diameter ranged from 153 to 307 µm. During ICGA, 91% showed increased their contrast and apparent size in late frames, whereas 79% of microaneurysms showed reduced contrast on late frames. OCT angiography was not contributive for the detection of these lesions. CONCLUSION: Late ICG staining revealing large microvascular abnormalities is commonly observed during DME. Because of their specific angiographic and OCT features relative to microaneurysms, we propose to name them telangiectatic capillaries (TelCaps).
