Anterior Segment Optical Coherence Tomography Assessment Of Corneal Thickness Before And After Pterygium Surgery

The main purpose of this study was to evaluate corneal thickness before and after primary pterygium surgery by anterior segment optical coherence tomography. 

Anterior Segment Optical Coherence Tomography is the key tool for assessment of the corneal thickness. Pterygium is one of the most common ocular surface disease. In this study; we evaluated one of the common corneal and conjunctival pathologies with Fourier‑domain OCT equipped with CAM

This study was performed between september 2020 and April 2021. Patients were recruited from outpatient clinic and inpatient wards of ophthalmology department in Qena University hospital. In each patient one eye was included in the study . 

Our study included 40 patients of both sexes and evaluation of corneal thickness revealed that thickness preoperative is 862.2 ± 93.4 µm and one week post operative is 480.1± 57.9 µm and one month post operative is 500.4 ± 56.1µm .. Mean of corneal thickness pre-operative /postoperative one week was 382.05 ± 100.2 with statically significant relationship with P value =0.00. Mean of corneal thickness pre-operative /postoperative one month was 361.67 ± 102.6 with statically significant relationship P value =0.00.Mean of corneal thickness one month post-operative /one week post-operative 20.37± 24. 5 with statically significant relationship P value 0.00. 

This study revelead that corneal thickness decreased after pterygium surgery and after one week from surgery the epithelium completely healed to reach average normal thickness which also affected by aging and some diseases .
