Central serous chorioretinopathy (CSCR) is a frequent cause of vision deterioration. Often it is associated with type 1 neovascularization under the pigment retinal epithelium (RPE). Optical coherence tomography angiography (OCT-angiography) enables non-invasive and contrast-free detection of neovessels in any retinal layer, which makes the method appropriate for diagnostics in CSCR. AIM: to investigate OCT-morphometric and angiographic parallels between different CSCR courses. MATERIAL AND METHODS: The study included 37 patients with CSCR...

PURPOSE: To report a case of "posterior scleral melanocytosis," a pigmented lesion of the posterior sclera that clinically resembles a flat choroidal nevus. METHODS: Case report of a patient with posterior scleral melanocytosis. Multimodal imaging, including swept source optical coherence tomography, was used to demonstrate the scleral location of the pigmented lesion and to distinguish its features from a typical choroidal nevus present in the same eye. RESULTS: An 86-year-old woman was seen for regular follow-up for neovascular age-related macular degeneration in her right eye and 2 pigmented lesions in her left eye, both presumed to be choroidal nevi...

Neovascular eye diseases, including retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration, threaten the visual health of children and adults. Current treatment options, including anti-vascular endothelial growth factor therapy and laser retinal photocoagulation, have limitations and are associated with adverse effects; therefore, the identification of additional therapies is highly desirable. Both clinical and experimental studies show that dietary ω-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFAs) reduce retinal and choroidal angiogenesis...

A 41-year-old male with pseudoxanthoma elasticum who presented with progressive vision loss in his left periphery is discussed. Bilateral angioid streaks, optic disc drusen, choroidal neovascularization, and peau d'orange were present. Imaging of the area with peau d'orange with adaptive optics scanning laser ophthalmoscopy and en face optical coherence tomography at Bruch's membrane (BM) revealed a pattern identical to the patches of peau d'orange visible with conventional fundus imaging techniques. These results show that structural abnormalities at the level of BM, likely a result of calcification, correlate with the characteristic "orange peel" pattern known as peau d'orange...

Dominique P Germain
Pseudoxanthoma elasticum (PXE) is a genetic metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. The lack of functional ABCC6 protein leads to ectopic mineralization that is most apparent in the elastic tissues of the skin, eyes and blood vessels. The clinical prevalence of PXE has been estimated at between 1 per 100,000 and 1 per 25,000, with slight female predominance. The first clinical sign of PXE is almost always small yellow papules on the nape and sides of the neck and in flexural areas...

INTRODUCTION: Autosomal recessive bestrophinopathy (ARB) is a retinal disease caused by biallelic mutations of the BEST1 gene. It has a variable phenotype with white flecks in the retina, multifocal yellow subretinal deposits, macular edema, choroidal neovascularization, hyperopia, and electrophysiological abnormalities. We describe a family with ARB and multigenerational inheritance. METHODS: Three generations of a Middle Eastern family (a woman, one son, and two grandchildren) were evaluated by our ocular genetics team...

Age-related macular degeneration (AMD) is one of the main causes of visual impairment in adults. Visual deterioration is more prominent in neovascular AMD with choroidal neovascularization (CNV). Clinical and postmortem studies suggested that complement system activation might induce CNV. In this study, we demonstrated that an anti-mouse complement component 5 (C5) antibody targeting MG4 domain of β chain effectively inhibited CNV which was induced by laser photocoagulation in mice. The targeted epitope of this anti-C5 antibody was different from that of currently utilized anti-C5 antibody (eculizumab) in the MG7 domain in which a single nucleotide polymorphism (R885H/C) results in poor response to eculizumab...

The innate immune system is activated in a number of degenerative and inflammatory retinal disorders such as age-related macular degeneration (AMD). Retinal microglia, choroidal macrophages, and recruited monocytes, collectively termed 'retinal mononuclear phagocytes', are critical determinants of ocular disease outcome. Many publications have described the presence of these cells in mouse models for retinal disease; however, only limited aspects of their behavior have been uncovered, and these have only been uncovered using a single detection method...
