The Effect of Pterygium Surgery on Corneal Topography
Neveen Melad Welson;
Abstract
Pterygium is a degenerative disease of the ocular surface with triangular fibrovascular tissue formation, which grows from the conjunctiva towards the surface of the cornea.
Pterygium causes impairment of vision by inducing astigmatism, as it causes localized central flattening to the apex of the pterygium.
The aim of this study is to assess the corneal changes induced by pterygium and effect of surgery on these changes through evaluation of the visual acuity and the corneal topography before and one month after the surgery and to study if these changes are reversible or not.
Fifty eyes of forty-one patients were included in this study. Twenty five male and sixteen female patients seeking pterygium surgery were recruited from the Ophthalmology Department Outpatient Clinic in Sohag Teaching Hospital during the period from July 2017 to May 2018.
