A Case of Fundus Falvimaculatus (A Phenotypic Variant of Stargardt Disease)

Jeyakumari J, Thasneem Suraiya .

Abstract


A 13 years old male attended OPD with chief  complaints of progressive painless diminution of   vision - 2 years. There was h/o perception of wavy lines and defective dark adaptation. There was no h/o defective field of vision or any history suggestive of cranial nerve dysfunction.

 

General and systemic examinations were normal.  The vision was 6/24 OU. Anterior segment examination was normal OU. Colour vision was defective in both the eyes. Dilated fundus examination showed OU - Beaten bronze appearance of Macula with pisciform flecks distributed throughout the fundus with absent foveal reflex.

 

Further investigations like FFA, EOG and OCT were done. OU fundus fluorescein angiography showed fundus autofluorescence and silent choroid.  Electroretinogram   was normal. OCT showed reduced foveal thickness in both eyes.

 

Owing to the presence of progressive painless loss of vision, beaten bronze appearance of macula with diffuse pisciform flecks, fundus auto fluorescence, with FFA showing dark and silent choroid, the patient was diagnosed to have Fundus flavimaculatus, a phenotypic form of Stargardts    disease and was prescribed low vision aids. Reassurance was given.

 

This case is presented for its visual manifestations and characteristic fundus findings.
