A new observation point: updating the nomenclature and classification with OCT
The evolution of ophthalmic imaging technologies has been particularly rapid over the last few years. The author provides an update of the current terms for common signs and pathologies observed using optical coherence tomography. My experience as an ophthalmic technician,...The challenge of chorioretinal folds in virtual eye clinics

EYE - Vitreo-Retinal, EYE - Orbit
Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...

EYE - Vitreo-Retinal
Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....

EYE - Vitreo-Retinal
This retrospective study of 30 eyes assessed the effect of anti-VEGF on morphology of pigment epithelial detachments (PED) secondary to age-related macular degeneration (AMD). Thirty eyes of 28 patients with PED were compared to 30 eyes of 30 patients with...

EYE - Vitreo-Retinal
Yannuzzi et al. report on their study aiming to evaluate the ability of optical coherence tomography angiography (OCTA) to differentiate vascularised from nonvascularised pigment epithelium detachments (PEDs) using conventional imaging techniques, including fundus fluorescein angiography (FFA) and indocyanine green (ICG),...
