Abstract

Purpose:

To present a case of macular hole associated with macular telangiectasia Type 2 (Mac-Tel 2) which underwent spontaneous closure.

Methods:

A 58-year-old woman is admitted with complaints of blurred and distorted vision. Optical coherence tomography, fundus autofluorescence, and optical coherence tomography angiography were performed for diagnosis and follow-up.

Results:

Optical coherence tomography revealed hyporeflective cavitations in both eyes, and full-thickness macular hole covered with internal limiting membrane drape in the left eye. Fundus autofluorescence showed loss of hypoautofluorescence in temporal parafoveal area in the right eye, and centrally in the left one. Vascular irregularities were detected in optical coherence tomography angiography images. The patient was diagnosed as Mac-Tel 2. During the follow-up, the macular hole underwent a process of spontaneous closure, starting as bridging at the level of external limiting membrane and outer nuclear layer followed by further repairment and organization of the outer plexiform layer, accompanied with visual gain.

Conclusion:

Spontaneous closure of macular hole in patients with Mac-Tel 2 is a rare entity. We hypothesize that extension or proliferation of Muller cells, which leads to reconstruction of normal foveal structure, is the main mechanism for this phenomenon.
