Summary
This study details early macular lesions in autosomal dominant central areolar choroidal dystrophy (CACD) in patients with good visual acuity. Findings clarify initial symptoms, aiding earlier diagnosis of this inherited retinal disease.
Area of Science:
- Ophthalmology
- Medical Genetics
Background:
- Central areolar choroidal dystrophy (CACD) is an inherited retinal disease.
- Autosomal dominant inheritance patterns are observed in affected families.
Observation:
- Sixty-nine members from two Caucasian families with CACD were examined using ophthalmoscopy and fundus photography.
- Macular lesions were identified in five individuals with preserved visual acuity.
Findings:
- Retinal function tests in three patients with lesions were normal.
- Fluorescein angiography revealed small parafoveal hyperfluorescent areas (retinal pigment epithelium loss) and macular pigment mottling in affected individuals with good vision.
Implications:
- This research provides the first clear description of early central areolar choroidal dystrophy lesions in patients with good visual acuity.
- These findings may improve early detection and management strategies for autosomal dominant CACD.
