Optical coherence tomography of idiopathic juxtafoveolar telangiectasia

Abstract

Background and objective: To document optical coherence tomography (OCT) findings in a series of eyes with group 2A idiopathic juxtafoveal telangiectasia.

Patients and methods: This study is a retrospective review of patient charts, OCT, fundus photography, and fluorescein angiography involving 23 eyes (12 patients). Mean retinal thickness in 9 macular areas was calculated and compared to previously published measurements from normal eyes.

Results: OCT in 8 of 13 stage 3 eyes revealed foveal cysts without evidence of cystoid macular edema on fluorescein angiography or biomicroscopy, and 1 lamellar hole. In stage 3 eyes, mild retinal thickening was found in 7 of 9 macular areas (P < .05).

Conclusions: OCT commonly reveals foveal cysts in stage 3 idiopathic juxtafoveal telangiectasia. Consistent findings of associated mild macular thickening and lack of late petaloid hyperfluorescence on fluorescein angiography suggest that these cysts differ in pathophysiology from cystoid macular
