Abstract Details

Purpose:

Myopia is the most common refractive error in the world, although correlations between myopia and the posterior segment of the eye are well established, this is not the case for myopia and the anterior segment, and even less for the cornea. The purpose is to study topographic, structural, and specular changes in myopic patients.

Setting:

Mohammed VI university hospital, Marrakech, Morocco.

Methods:

A total of 100 subjects were enrolled; they were divided into 3 groups according to their state of refraction: low myopia (-0.25 to -3.0 D), moderate myopia (-3.0 to -6.0 D) and high myopia (more than -6.0 D). Patients underwent elevation topography,  AS OCT  with epithelial mapping and specular microscopy. Characteristics were compared between the 3 groups.

Results:

There was a significant difference in corneal thickness with greater infero-nasal thickness and keratometric values ​​between the 3 groups. People with high myopia tend to have a thinner corneal epithelium than low to moderate myopic patients. There was no significant difference in specular microscopy between the 3 groups. Corneal thickness has been correlated with the degree of myopia.

Conclusions:

Our study shows corneal changes most likely related to the degree of myopia. Further studies are needed to confirm this hypothesis.
