    1. Correlation between laser speckle flowgraphy and optical coherence tomography angiography measurements in normal and glaucomatous eyes

      Correlation between laser speckle flowgraphy and optical coherence tomography angiography measurements in normal and glaucomatous eyes

      Purpose: To investigate the relationship between laser speckle flowgraphy (LSFG) and optical coherence tomography angiography (OCTA) measurements of the peripapillary retina and optic nerve head (ONH) in normal eyes and eyes with primary open-angle glaucoma (POAG). Patients and methods: One eye from each of 46 normal subjects and mild and moderate/advanced POAG patients were included. ONH blood flow acquired by LSFG, circumpapillary vessel density (cpVD, a 250 μm-wide elliptical annulus around the optic disc), and intra-papillary vessel density (ipVD, a 1.5×1.5 mm scan field) acquired by OCTA were measured. Their values were compared among normal controls ...

    2. Optical coherence tomography findings of falciform retinal detachment complicated with persistent fetal vasculature

      Optical coherence tomography findings of falciform retinal detachment complicated with persistent fetal vasculature

      Background Falciform retinal detachment (FRD) usually causes pronounced retinal wrinkles, and the prognosis of visual function is poor. In this present study, we report a rare case of FRD in which optical coherence tomography (OCT) findings revealed a relatively good visual function. Case presentation This study involved a 22-year-old female who had previously been diagnosed with FRD at 2 years of age, and who presented with microphthalmus in both eyes with pronounced retinal folds from the optic disc to the inferior-temporal side. Based on the clinical findings, we diagnosed it as persistent fetal vasculature (PFV). We found the visual function ...
