Evaluation of Effect of Pterygium on the Endothieleal Cell Density of the Cornea by Specular Microscopy

E.S.Ahmed, A.A.El Shayeb and R.M. Uosry"


Pterygium were reported to induce changes much deeper and to result in a decrease in the corneal endothelial cell density. Past investigations demonstrated the injurious impact of pterygium on corneal endothelium proposes that pterygium is identified with an abatement in corneal endothelial cell thickness. The point of the current examination is to research the progressions of corneal endothelial cell thickness in patients with pterygium. Forty eyes with pterygium of patients speak to the objective patients of this investigation; they were ordered into two equivalent gatherings every one of 20 eyes: Group (I): 20 eyes with beginning time pterygium. Gathering (II): 20 eyes with full created pterygium. Gathering (III) 40 contralateral typical eyes. There was measurably critical contrast among three contemplated bunches as respect mean corneal force (KM), endothelial cell thickness (ECD) and corneal astigmatism (AST). The mean of KM was higher in bunch III (44.4 ± 0.22, 2498 ± 100.6 separately) than bunch I (43.4 ± 0.29, 2496.7 ± 92.1 individually) and II (42.7 ± 0.33, 2156.2 ± 138.9). The mean of ECD was lower in bunch II (2156.2 ± 138.9) than bunch I (2496.7 ± 92.1) and III (2498 ± 100.6). The mean of AST was higher in bunch II (- 6.2 ± 0.77) than bunch I (- 1.2 ± 0.41) and III (- 0.61 ± 0.21). Careful mediation ought to be considered in patients with broad pterygium included the cornea or creating a noteworthy increment in astigmatism Watchwords: Pterygium; Endothieleal Cell Density; Cornea; Specular Microscopy.
