Macular hard drusen in the right eye. 65-year-old diabetic woman. Drusen , from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye .
Indocyanine green angiography (ICGA), [10] and OCT angiography (OCTA) [11] [12] [13] studies have provided support for choriocapillaris involvement. However, a novel hypothesis was proposed implicating a direct neurotropic infection as a possible underlying cause given the dynamic changes observed along the neuronal pathway of the retina [ 14 ]
Acute posterior multifocal placoid pigment epitheliopathy primarily occurs in adults (with a mean age of 27). [1] Symptoms include blurred vision in both eyes, but the onset may occur at a different time in each eye. There are yellow-white placoid lesions in the posterior pole at the level of the retinal pigment epithelium. Some suggest a ...
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) is a harmless, pigmented fundus lesion that can be of various forms: solitary, grouped, and atypical, [1] and are found through clinical eye screenings from digital retinal imaging often established by ophthalmologists. [2]
Macular hypoplasia (or foveal hypoplasia) is a rare medical condition involving the underdevelopment of the macula, [1] a small area on the retina (the eye's internal surface) responsible for seeing in detail and sensing light. [2] Macular hypoplasia is often associated with albinism. [1]
The macula (/ˈmakjʊlə/) [1] or macula lutea is an oval-shaped pigmented area in the center of the retina of the human eye and in other animals. The macula in humans has a diameter of around 5.5 mm (0.22 in) and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.
Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
The fundus exam via ophthalmoscopy is essentially normal early on in cone dystrophy, and definite macular changes usually occur well after visual loss. Fluorescein angiography (FA) is a useful adjunct in the workup of someone suspected to have cone dystrophy, as it may detect early changes in the retina that are too subtle to be seen by ...
