Optical coherence tomography in group 2A idiopathic juxtafoveolar telangiectasis

To describe the optical coherence tomographic features in patients with group 2A idiopathic juxtafoveolar telangiectasis.

Forty eyes of 20 consecutive patients with idiopathic juxtafoveolar telangiectasis seen between August 2002 and January 2004 were included in the study. All of the patients underwent color fundus photography, fluorescein angiography, and optical coherence tomography. The main outcome measure was optical coherence tomography findings.

The most consistent finding between stages 2 through 5 of group 2A idiopathic juxtafoveolar telangiectasis seen in 35 (87.5%) eyes on optical coherence tomography was the presence of hyporeflective intraretinal spaces in the absence of retinal thickening. Other findings included the presence of hyperreflectivity in the middle or inner retinal layers, suggesting retinal pigment epithelium proliferation and migration corresponding to the stellate foci of pigmentation in stage 4 and features of choroidal or subretinal neovascular membrane in stage 5.

The optical coherence tomography findings in group 2A idiopathic juxtafoveolar telangiectasis were characteristic and may be helpful in making the diagnosis and defining, as far as possible, the anatomical staging.
