Abstract:
Objective:To describe a case of adult-onset foveomacular vitelliform dystrophy
(AOFVD).
Method:This is a case report.
Results:A 22-year-old female presented with painless blurring of vision and metamorphopsia 3 days prior to consultation. There were 2 similar episodes in the past that spontaneously resolved after 2 to 4 weeks. Visual acuity (VA) was 20/50 in the right eye (OD) and 20/40 in the left (OS), both best corrected to 20/25. Dilated-fundus examination revealed a discrete area of mixed hypoand hyperpigmentation 1 disc diameter over the fovea in OD and a solitary round hypopigmented lesion with a hyperpigmented border 3 to 4 disc diameters on the fovea in OS. Fluorescein angiography (FA) revealed an area of hyperfluorescence surrounded by a rim of hypoflourescence in OD and an area of blocked fluorescence with subtle hyperfluorescence superior to the lesion in OS, both of which did not increase in size and intensity toward the late phases. Optical coherence tomography (OCT) revealed neurosensory detachment in both eyes. Electrooculogram (EOG) was normal with Arden ratio of 0.91. VA returned to 20/25 in both eyes, and repeat fundus photography showed no change in the characteristics of the lesions.
Conclusion:Differential diagnosis of a hypopigmented macular lesion in the young with self-limited blurring of vision should include AOFVD. FA, OCT, and EOG can help distinguish AOFVD from Best’s disease or other similar macular conditions. - Full text:PJO 108.pdf
