Novel retinal imaging abnormalities in alport syndrome.

PURPOSE:The purpose of this study was to report a novel observation during retinal screening of a child with Alport syndrome. METHODS:This was a review of case record and imaging files. RESULTS:Clinical examination of the retina and standard color fundus photography revealed no abnormality. However, distinct and identical wrinkling of the temporal macula (fingerprint sign) in both eyes was noted on Optos pseudocolor images of the retina. On optical coherence tomography, there were corresponding "saw-tooth" corrugations in the middle layers of the retina. En face images further highlighted the characteristic nature of this unusual observation. CONCLUSION:Fingerprint sign in the retina, a heretofore undescribed feature, is reported in a child with biopsy confirmed Alport syndrome.
