Nargis Nizam Ashraf, Abdul Rasheed Khokar and Eisha Safia Ashraf

ABSTRACT

Objective: To assess difference in corneal parameters on specular microscopy in emmetropic and astigmatic eyes.

Study Design: Retrospective / Comparative study

Place and Duration of Study: This study was conducted at the Department of Ophthalmology, Unit-I, Dow University of Health Sciences, Karachi from January 2020 to February 2021.

Materials and Methods: The study included 112 eyes of 56 patients. 28 patients were emmetropes and 28 were astigmatic. Rexxam SPM-700 specular microscope was used. Endothelial cell count, and Central corneal thickness were measured. Differences were analyzed between the normal and astigmatic eyes.

Results: The Mean Central corneal thickness in the right eye in astigmatic patients came out to be 536.89 microns. That in the left eye was 539.61 microns. The Mean Central Corneal thickness in the right eye in non-astigmatic  came out to be 553.64, whereas in the left eye it was 559 microns. The Mean Cell density in the right eye in astigmatic patients was 2060.36 per mm square. That in non-astigmatic patients it was 1942.18 per mm square. Mean Cell density in the left eye in astigmatic patients was 1974.50 per mm square and that in non-astigmatic patients was 1935.96 per mm square.

Conclusion: The Central corneal thickness in the non-astigmatic eyes on specular microscopy was found to be
more as compared to the astigmatic eyes. The Cell density was more in astigmatic eyes in comparison to non-astigmatic eyes.

Key Words: Specular microscopy, astigmatism, central corneal thickness, corneal endothelium.
