Purpose:
We study the prevalence of retinal tears and holes in myopia. We consider age distribution, also retinal localization, and its relationship with the different types of posterior vitreous detachment.
Material And Methods:
200 eyes from 124 myopic patients were selected. Average age was 34,76 years. Five groups of myopia were considered, and three groups of age. Indirect ophthalmoscopy under cycloplegia, scleral indentation and biomicroscopy with three mirror Goldmann contact lens were performed in all the patients.
Results:
7 tears were found in 6 eyes out of the 200 myopic eyes studied (3%), and 16 holes in 14 eyes (7%). No statistical relationship was found for tears or holes between the different groups of myopia or age, neither considering the different types of posterior vitreous detachment. Superotemporal retinal quadrant was more frequently involved by these lesions.
Conclusions:
The tears and round trophic holes found (3% and 7% respectively) did not show relationship with posterior vitreous detachment type, age nor myopic grade.
