Epiretinal Membrane in Dome-Shaped Macula Complicated with Serous Retinal Detachment: Transient Efficacy of Surgery

Case Reports in Ophthalmology, 2017
Dome-shaped macula (DSM) is an entity recently described as a convex anterior protrusion of the macular area within a posterior myopic staphyloma. Specific complications were associated with DSM, like serous retinal detachment (SRD).

Comparison of 5-year progression of retinitis pigmentosa involving the posterior pole among siblings by means of SD-OCT: a retrospective study [PDF]

, 2018
The blockchain technology promises to transform finance, money and evengovernments. However, analyses of blockchain applicability and robustness typicallyfocus on isolated systems whose actors contribute mainly by running the consensusalgorithm. Here, we

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Three hundred sixty‐degree prophylactic laser retinopexy versus focal laser during rhegmatogenous retinal detachment repair: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the anatomic, functional and safety outcomes of intra‐operative 360‐degree prophylactic laser retinopexy versus focal laser retinopexy during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) and to assess the certainty of evidence.

epiretinal membrane

, 2023
Epiretinal membrane (ERM) is formed at the vitreoretinal interface that leads to a myriad of visual disturbances includes decrease in visual acuity (VA), stereopsis, contrast sensitivity and metamorphopsia. Most common etiology of ERM is posterior vitreous detachment (PVD) and is usually labeled as idiopathic.
