Pattern dystrophy of the retinal pigment epithelium
Ophthalmology
|December 1, 1982
Summary
Pattern dystrophies are rare inherited eye diseases affecting the retina. This study expands understanding of their varied clinical presentation and progression in two families.
Area of Science:
- Ophthalmology
- Genetics
- Retinal Diseases
Background:
- Pattern dystrophies are hereditary macular diseases involving retinal pigment epithelium (RPE) lesions.
- Lesions present as dots, lines, or branched figures, impacting vision.
Observation:
- Two pedigrees with pattern dystrophies were studied, expanding the known clinical spectrum.
- Onset typically occurs in the second or third decade of life.
Findings:
- Significant variation in fundus appearance and potential for severe vision loss were observed.
- Electroretinography (EOG) results were not consistently abnormal; fundus lesions showed changes over time.
Implications:
- Findings suggest pattern dystrophies may involve abnormal lipofuscin accumulation in RPE cells.
- Understanding the clinical spectrum aids in diagnosis and management of these rare retinal conditions.
