Retinal functions in dominant cystoid macular dystrophy (DCMD)
Acta Ophthalmologica
|October 1, 1976
Summary
Dominant cystoid macular dystrophy (DCMD) causes vision loss through macular edema and retinal leakage. This genetic condition affects color vision and may present with peripheral pigment changes.
Area of Science:
- Ophthalmology
- Medical Genetics
- Retinal Diseases
Background:
- Dominant cystoid macular dystrophy (DCMD) is a hereditary retinal disorder.
- Characterized by specific ocular manifestations affecting central vision.
Purpose of the Study:
- To describe the clinical features and inheritance patterns of DCMD.
- To analyze the visual function and fundus findings in affected individuals.
Main Methods:
- Clinical examination of 28 members across 5 families.
- Ophthalmic testing including color vision, electroretinography (ERG), and electrooculography (EOG).
Main Results:
- DCMD presents with cystoid macular edema and retinal capillary leakage.
- Affected individuals exhibit red-green and blue-yellow color vision defects.
- Electrooculography (EOG) is subnormal, while electroretinography (ERG) is normal.
- Peripheral pigmentary alterations are frequently observed.
Conclusions:
- DCMD is a distinct genetic condition with characteristic macular and vascular abnormalities.
- The observed visual defects correlate with the pathological findings.
- Further research into the genetic basis and progression of DCMD is warranted.
