Purpose:
To investigate morphologic features of group 2A idiopathic juxtafoveolar retinal telangiectasis (IJRT) with three-dimensional optical coherence tomography (OCT).
Design:
Observational case series.
Methods:
We performed OCT ophthalmoscopy on six eyes of three consecutive patients with group 2A IJRT.
Results:
Thin cystic low-intensity space within inner and outer retinal layers was detected with the longitudinal B-scan through the fovea in five eyes. Partial loss of highly reflective line considered as the boundary between photoreceptor inner segments and outer segments was also detected. The transverse C-scan provided en-face images of the low-intensity space shown with the B-scan, if not entirely. These morphologic alterations appeared not to correspond with the staining observed in the late phases of fluorescein angiography.
Conclusions:
The OCT ophthalmoscope could visualize morphologic alterations indicating degeneration or atrophy of neurosensory retina, including photoreceptor layers. These alterations may play a role in the pathogenesis of group 2A IJRT.
