Purpose:
To report the clinical and angiographic features of two monozygotic twins affected by bilateral group 2 idiopathic juxtafoveolar telangiectasis.
Method:
Case reports.
Results:
Two 64-year-old women, who were identical twins, were suffering from visual loss. One twin had suffered from visual loss for 1 year and had a visual acuity of 20/25 in both eyes, and the other twin had suffered for 2 years and had a visual acuity of 20/30 in both eyes. Fluorescein angiography disclosed similar fundus features. An analogous area of capillary telangiectasis and leakage was observed in the right macula, where no intraretinal pigment was seen; the left macula showed a similar amount of intraretinal pigment associated with tiny right-angle venules and minimal leakage.
Conclusion:
This observation raises the issue of genetic influences in the pathogenesis of this disease.
