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

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
