Myopia is not a simple refractive error, but an eyesight-threatening disease. There is a high prevalence of myopia, 80% to 90%, in young adults in East Asia; myopia has become the leading cause of blindness in this area. As the myopic population increases globally, the severity of its impact is predicted. Approximately one fifth of the myopic population has high myopia (≥-6 diopters), which results in irreversible vision loss such as retinal detachment, choroidal neovascularization, cataracts, glaucoma, and macular atrophy...

Ophthalmologic involvement in Sturge-Weber-Krabbe syndrome (SWKS) is present in 30-70% of cases and needs to be reviewed because of its impact on visual development. We report a case of a newborn for whom SSWK with ophthalmologic involvement was suspected. She had a right segmental plane angioma associated with right congenital glaucoma and suspected right pial angioma. Ophthalmic involvement in SWKS may be nonocular: iatrogenic by treatment-associated complications and central by leptomeningeal damage. Ophthalmologic involvement can occur throughout childhood and is mainly represented by glaucoma and diffuse choroidal hemangioma and then conjunctival hemangioma, retinal detachment, and iris heterochromia...

Optical coherence tomography (OCT) has become an established diagnostic technology in the clinical management of age-related macular degeneration (AMD). OCT is being used for primary diagnosis, evaluation of therapeutic efficacy, and long-term monitoring. Computer-based advances in image analysis provide complementary imaging tools such as OCT angiography, further novel automated analysis methods as well as feature detection and prediction of prognosis in disease and therapy by machine learning. In early AMD, pathognomonic features such as drusen, pseudodrusen, and abnormalities of the retinal pigment epithelium (RPE) can be imaged in a qualitative and quantitative way to identify early signs of disease activity and define the risk of progression...

PURPOSE: To identify signs occurring more frequently in retinal angiomatous proliferation (RAP) lesions compared with other types of choroidal neovascularization (CNV) in age-related macular degeneration. METHODS: In this cross-sectional retrospective study, 30 patients were evaluated. These signs were correlated with the type of CNV: shunting of blood flow to the lesion by fluorescein angiography, late leakage by indocyanine green angiography, intraretinal cysts and retinal pigmented epithelium interruption along the retinal pigmented epithelium detachment with a hyperreflective oval area by spectral domain optical coherence tomography, and presence of reticular pseudodrusen by infrared light...

Technologies for multimodal digital imaging of vitreoretinal diseases have improved the accuracy of diagnosis and the depth of the knowledge of the mechanisms of disease and their response to treatments. Optic coherence tomography (OCT) has become a mandatory tool for the management and for the follow-up of retinal pathologies. OCT technology evolved in the last two decades from time-domain to spectral domain and recently to the swept-source OCTs (SS-OCT). SS-OCT improved the depth of imaging and the scan speed, thus adding novel algorithms and features such as for vitreous and vitreoretinal interface evaluation, choroid segmentation and mapping, OCT angiography and En-face OCT...

AIM: Posterior vitreous detachment (PVD) is a physiological phenomenon due to aging characterized by separation of the vitreous cortex from the retina and may induce a variety of pathological events at the vitreoretinal junction. The aim of this study is to highlight in vivo anatomical and functional changes in early stages of PVD allowing the correct treatment. MATERIAL AND METHODS: Non-consecutive case series; optical coherence tomography (OCT) relies on analyzing the reflectivity of coherent light from different anatomical interfaces within posterior vitreous and retinal histological layers, thus acquiring transverse sections through vitreoretinal interface, sensory retina, retinal pigment epithelium and choroid...
