Background. In recent years, deep learning has been increasingly applied to a vast array of ophthalmological diseases. Inherited retinal diseases (IRD) are rare genetic conditions with distinctive phenotype on fundus autofluorescence imaging (FAF). Our purpose was automatically classify different IRDs by means FAF images using algorithm. Methods. this study, patients retinitis pigmentosa (RP), Best disease (BD), Stargardt (STGD), as well healthy comparable group were used train multilayer...

Descemet membrane endothelial keratoplasty (DMEK) is the preferred method for treating corneal dysfunction, such as Fuchs dystrophy (FECD). The surgical indication based on patients' symptoms and presence of edema. We developed an automated tool deep learning to detect edema in optical coherence tomography images. This study aimed evaluate this approach detection before surgery, patients with or without FECD.We used our previously described model allowing classify each pixel images "normal"...

To report the first known case of Descemet's Membrane Endothelial Keratoplasty (DMEK) graft rejection following COVID19 infection.A 60-year-old woman with a history DMEK for Fuch's dystrophy, presented redness and vision loss in her operated eye 18 months after surgery. Further clinical revealed systemic symptoms consistent COVID19, which had started 3 weeks prior to onset ocular symptoms. Examination rejection, despite patient compliance maintenance topical corticosteroid therapy....

To evaluate the sensitivity and specificity of ultrawide-field fundus photography (UWF-FP) for detection classification sickle cell retinopathy (SCR) by ophthalmologists with varying degrees expertise in retinal disease. Patients presenting disease (SCD) Créteil University Eye Clinic, having undergone UWF-FP fluorescein angiography (UWF-FA) on same day, were retrospectively included. Eyes previous photocoagulation excluded. SCR was graded independently UWF-FA using Goldberg two levels....

We report a case of discordant keratoconus (KC) in set monozygotic twins with contrasting environmental risk factors. Twin one had bilateral, asymmetrical KC. He reported significant eye rubbing using his knuckles during night-shift work as an emergency doctor. His usual sleeping position on the left side corresponded to most affected eye. two normal corneas, no evidence mild infrequent rubbing, daytime pattern, and supine position. This highlights influence behavioural factors development...

The accurate detection of corneal edema has become a topic growing interest with the generalization endothelial keratoplasty. Despite recent advances in deep learning for detection, problem minimal remains challenging. Using transfer and limited training set 11 images, we built model to segment epithelium, which is part three-model pipeline detect edema. A second third are used on stroma alone epithelium. validation 233 images from 30 patients consisting three groups (Normal, Minimal Edema...

Abstract Background Pathologic myopia is a major cause of visual impairment and blindness. Case presentation We report case an immediate post partum macular subretinal bleeding observed in highly myopic patient. A 30-years-old woman presented two days after childbirth for sudden loss vision her right eye. Multimodal imaging showed hemorrhage masking subtle yellowish linear lesion corresponding to lacker crack. Due the lack evidence choroidal neovascularization, simple clinical monitoring was...
