Background: Anterior Segment Optical Coherence Tomography is the key tool to assess the corneal thickness. Pterygium is one of the most common ocular surface diseases. Our research about evaluation one of the corneal and conjunctival disorders with anterior segment OCT
Objectives: Main purpose for our study is to evaluate corneal thickness before and after pterygium excision by anterior segment OCT.
Patient and Methods: This study was performed between September 2020 and April 2021. Cases 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.
Results: 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 /post-operative 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.
Conclusion: This study revealed that corneal thickness decreased after pterygium surgery and after one week from surgery the epithelium completely healed to reach average normal thickness which is also affected by aging and some diseases.
