The authors report a case of a congenital hypertrophy of the retinal pigment epithelium (CHRPE) associated with choroidal neovascularization (CNV) causing symptomatic vision loss. Two intravitreal injections of bevacizumab (Avastin; Genentech, South San Francisco, CA) 4 weeks apart resolved the fluid and improved the visual acuity. This case demonstrates that CHRPE can rarely be complicated by CNV, which may respond to intravitreal bevacizumab therapy. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:276-277.].

To report a retinal pigment epithelium (RPE) tumor with exudative maculopathy, originating from an atypical RPE lesion presumed to represent congenital hypertrophy of the RPE or RPE hyperplasia.
Congenital simple hamartoma of the retinal pigment epithelium (CSHRPE) is an uncommon benign lesion with characteristic clinical features. Ophthalmoscopically it appears as a small localized, well cir...
To assess efficacy of intravitreal ranibizumab in retinal pigment epithelium tears secondary to neovascular age-related macular degeneration.
To report the case of a small pigmented tumor in the macular region investigated using optical coherence tomography angiography (OCT-A) in the context of a multimodal approach.
This project intends to transplant the clinical grade human embryonic stem cells derived retinal pigment epitheliums into subretinal space of patients to treat dry age-related macular dege...
Geographic atrophy (GA) causes the loss of the retinal pigment epithelium (RPE) cells in broad areas of the retina. The application of subthreshold micropulse laser spots in healthy RPE in...

Colloid or hyaline bodies lying beneath the retinal pigment epithelium. They may occur either secondary to changes in the choroid that affect the pigment epithelium or as an autosomal dominant disorder of the retinal pigment epithelium.
The single layer of pigment-containing epithelial cells in the RETINA, situated closely to the tips (outer segments) of the RETINAL PHOTORECEPTOR CELLS. These epithelial cells perform essential functions for the photoreceptor cells, such as in nutrient transport, phagocytosis of the shed photoreceptor membranes, and ensuring retinal attachment.
A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.
The portion of a retinal rod cell situated between the ROD INNER SEGMENT and the RETINAL PIGMENT EPITHELIUM. It contains a stack of photosensitive disk membranes laden with RHODOPSIN.
A specialized transport barrier, in the EYE, formed by the retinal pigment EPITHELIUM, and the ENDOTHELIUM of the BLOOD VESSELS of the RETINA. TIGHT JUNCTIONS joining adjacent cells keep the barrier between cells continuous.
Congenital conditions are those which are present from birth. They include structural deformities or loss of function in organs such as the <!--LGfEGNT2Lhm-->heart, gut or skeletal system. They can be corrected by <!--LGfEGNT2Lhm-->surgery, m...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
