Abstract Details

Purpose:

To assess the topographic corneal changes and the incidence of keratoconus in children with myopia and myopic astigmatism.

Setting:

It is a prospective study, in which we studied 174 eyes of children with myopia and/or astigmatism between June 2013 and December 2014, in Elminya, Egypt.

Methods:

All patients were examined to assess the refractive error and corneal examination using pentacam to evaluate the corneal abnormalities (curvature, pachymetry, anterior and posterior elevation.

Results:

The mean age was 11.05±1.98 years, 54% were males. On studying the sagittal corneal curvature, the mean k was 46.4±2.77D (41.4 to 54.3). The mean spherical error was -4.75±2.97 (zero to -11.50D). The mean cylindrical error was -4.12±1.78D (-0.50 to -8). The mean thickness of the thinnest corneal point was 535.05±41.66 µm ( 440 to 623µm). Keratoconus found in 31 eyes (17.8%). The mean anterior elevation was 14.55±9.96mm(4 to 55 mm), and the mean posterior elevation was 28.33±16.66mm (12 to 85 mm). Amblyopia found in 64 eyes (36.78%). We found that 23% had vernal keratoconjunctivitis and 93% of them had the severest form of corneal affection.

Conclusions:

Children with myopia and myopic astigmatism have corneal abnormalities which is more pronounced in cases with astigmatism and vernal keratoconjunctivitis. Corneal examination should be performed for any ametropic child to detect any corneal abnormality and to treat it as early as possible to avoid the development of keratoconus or its worsening.
