Abstract

Purpose
To evaluate macular ganglion cell-inner plexiform layer (mGCIPL) thickness and peripapillary retinal nerve fiber layer (pRNFL) thickness in eyes with idiopathic macular telangiectasia type II (Mactel).
Methods
Retrospective cross-sectional study including 26 eyes (14 subjects) diagnosed with idiopathic macular telangiectasia type II (Mactel group) and 26 eyes of 26 healthy control subjects (control group). The pRNFL thickness and mGCIPL thickness were measured using spectral-domain optical coherence tomography.
Results
Average, minimum, superotemporal, and inferotemporal mGCIPL thicknesses in the Mactel group were significantly thinner than in the control group. There was no significant difference in pRNFL thickness between the two groups.
Conclusions
mGCIPL thickness decreased in the Mactel group compared with the control group.
