Purpose To describe optical coherence tomography (OCT) findings in patients with juxtafoveal retinal telangiectasis (JRT). Methods Fourteen consecutive patients (28 eyes) with JRT (12 patients with JRT type II, one with JRT type I and one with JRT type III) were examined using fluorescein angiography (FA) and OCT. Results Despite prominent leakage in FA, macular oedema was absent in all 26 eyes ...

Purpose To describe optical coherence tomography (OCT) findings in patients with juxtafoveal retinal telangiectasis (JRT). Methods Fourteen consecutive patients (28 eyes) with JRT (12 patients with JRT type II, one with JRT type I and one with JRT type III) were examined using fluorescein angiography (FA) and OCT. Results Despite prominent leakage in FA, macular oedema was absent in all 26 eyes with type II JRT. In contrast to that, in patients with type I and type III JRT, cystoid macular oedema was evident. In 14 of 28 eyes (all with type II JRT), a single foveal cyst was found in OCT. It varied significantly in size and was associated with visual acuity decrease. An intraretinal hyperreflective lesion was seen in eight of 28 eyes and flattening of the fovea in three eyes. Conclusions Foveal cyst, absent macular oedema, intraretinal hyperreflective lesions and foveal flattening were the most common OCT findings in patients with JRT type II. These may represent progressive loss of retinal tissue, possibly due to Muller cells degeneration, and provide additional diagnostic criteria for JRT.
