Adaptive optics scanning light ophthalmoscopy (AOSLO) allows noninvasive assessment of the cone photoreceptor mosaic. Confocal AOSLO imaging of patients with achromatopsia (ACHM) reveals an altered reflectivity of the remaining cone structure, making identification of the cells more challenging than in normal retinas. Recently, a “split-detector” AOSLO imaging method was shown to enable direct visualization of cone inner segments in patients ... إقراء المزيد

Results: ... إقراء المزيد

Purpose The aim of the study was to detect the effect of intravitreal ranibizumab injection on treatment of macular edema induced by central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) by measuring the improvement in best-corrected visual acuity (BCVA) (LogMAR) and the reduction in central retinal thickness (CRT) measured by optical coherence tomography. Patients and methods In ... إقراء المزيد
