Central areolar choroidal dystrophy can cause vision loss and color vision deficits. Early stages show macular changes and choriocapillaris atrophy, indicating this is a primary finding.
Area of Science:
- Ophthalmology
- Medical Genetics
Background:
- Central areolar choroidal dystrophy (CACD) is a rare inherited retinal disease.
- It primarily affects the macula, leading to progressive vision loss.
Abstract:
Three members of a family with central areolar choroidal dystrophy showed the early and late stages of this disorder. The youngest affected was a 12-year-old girl who exhibited decreased vision, a red-green dyschromatopsia, and mild granularity of the macula with a diffuse foveal reflex. A discrete focal loss of choriocapillaris in the macula was seen on fluorescein angiography. This indicates that choriocapillaris atrophy is an early finding in this disease.
