Aim:To assess the efficacy of focal photocoagulation of capillary macroaneurysms (CMA) to reduce the burden of intravitreal injections (IVI) in patients with macular edema (ME). Materials and Methods: Retrospective multicenter study in patients with diabetic ME or ME secondary to retinal vein occlusion (ME-RVO). CMA associated with ME were selectively photocoagulated. Patients were followed for one year after photocoagulation. Results: 93 eyes of 76 patients were included in this study. At 6 months after the laser (n = 93), there was a significant decrease in mean macular thickness (from 354 µm to 314 µm, p < 0.001) and in mean IVI number (from 2.52 to 1.52 at 6 months, p < 0.001). The mean BCVA remained stable (0.32 and 0.31 logMAR at baseline and 6 months, p = 0.95). At 12 months (n = 81/93), there was a significant decrease in mean macular thickness (from 354 µm to 314 µm, p < 0.001) and in mean IVI number (from 4.44 to 2.95 at 12 months, p < 0.001), while the mean BCVA remained stable (0.32 and 0.30 logMAR at baseline and 12 months, p = 0.16). Conclusion: Focal laser photocoagulation of CMA seems to be effective and safe for reducing the burden of IVI in patients with ME. Their screening during the follow-up should be considered closely.
Choroidal neovascularization (CNV) is a rare but severe complication in Best disease and autosomal recessive bestrophinopathy. However, the visualization of the neovascular membrane is difficult on fluorescein angiography (FA) and indocyanine green angiography (ICGA) because of dye leakage due to the accumulation of material. The authors' study reports a case series of pediatric Best disease where optical coherence tomography angiography (OCTA) contributed to the diagnosis of CNV and prompt treatment. Five eyes of three patients were included (two Best disease and one autosomal recessive bestrophinopathy). The mean age at diagnosis was 6.8 years ± 1.8 years (range: 5 years to 10 years). OCTA showed the typical “sea fan-shaped” neovascular membrane in all five eyes, whereas, in most cases, conventional imaging by FA and ICGA did not show clearly the neovascularization due to masking effect of the vitelliform material. OCTA seems to be a good alternative to diagnosing CNV in Best disease, especially in children, as it is a noninvasive, rapid technique for imaging, and does not require the administration of dyes.
