Macular dystrophy in a 9-year-old boy with fundus albipunctatus

Am J Ophthalmol. 2002 Feb;133(2):278-80. doi: 10.1016/s0002-9394(01)01304-6.

Abstract

Purpose: To report a 9-year-old boy with fundus albipunctatus and macular dystrophy.

Design: Observational case report.

Methods: A complete ophthalmic examination was performed. The 11-cis retinol dehydrogenase gene (RDH5) was examined by direct genomic sequencing.

Results: The fundi of the 9-year-old boy showed numerous yellow-white punctata as well as foveal atrophic lesions in both eyes. His corrected visual acuity was RE: 0.5 and LE: 0.3. Scotopic full-field electroretinograms were not present after 20 minutes of dark-adaptation but were normal after 3 hours of dark-adaptation. Full-field cone and 30-Hz flicker electroretinograms were normal; however, focal macular cone electroretinograms were significantly reduced. A compound heterozygous mutation of Tyr281His and Leu310GluVal in RDH5 was detected.

Conclusion: We suggest that the macular dystrophy is caused by the RDH5 mutation as a phenotype variation in fundus albipunctatus.
