Macular Microhole. Presentation of 6 Cases

Abstract

 

Purpose:

 

To clinically describe the appearance of Macular Microhole in OCT

 

Methods:

 

Fifteen eyes of 9 patients that presented a focal lamellar or cystoid defect in the posterior hyperreflective layer in the foveal zone where analyzed by HR OCT. None of them had a history of direct light exposure either to solar light, eclipse or history of trauma

 

Results:

 

Average age was 52,7 yo (21 - 97) and mean refractive error was -1.1 D. (-5 / +2). Most of them presented lesion in both eyes (6/9). Symptoms where central scotoma, metamorphopsia and low VA. Some cases where asymptomatic. Nine eyes (64%) presented VA >20/40. Most patients did not show any changes neither in the OCT or VA (8-32 months).In the HD OCT these patients presented either a lamellar or cistoid defect well circuscribed in the outeretina, correspondant to the IL/OL photoreceptor layer and/or the RPE

 

Conclusions:

 

Macular Microhole is a nonprogressive, benign, usually bilateral entity. It is usually asymptomatic, or it presents minimum visual symptoms. Its aspect in the HR OCT is characteristic, but sometimes it can not be distinguished from maculopathy caused by solar exposure, eclipse or trauma. Diagnosis should exclude exposure to this entities.
