Abstract

Purpose: To study the influence of dimensions of the telangiectasia (MacTel) measured using the enface OCT-A on various clinical and OCT parameters in eyes with MacTel type 2. 

Methods: Structural OCT and swept source based OCT-A was performed for all consenting patients and the MacTel was classified based on location. The maximum dimensions of the MacTel in the deep plexus, both vertical and horizontal, was noted using calipers.

Results: Vision gradually reduced with increment in OCT-A grades of MacTel from grade 1 to 3, however the continuum was not maintained in grade 4 MacTel which showed better vision and lesser degenerative cysts.

Conclusion: Larger telangiectasias are associated with significantly lower vision in MacTel. Eyes with deeper telangiectasia involving outer retina have better vision and evidence of far lesser neurodegeneration that type 3 disease, suggesting that this may not be part of the continuum and does not represent neovascularization.
