Abstract

Background: Pterygium is unnatural fibrovascular and epithelial cells proliferation towards cornea, visiual impairment and astigmatism induction are common complications. Objective: Compare conjunctival autograft and transposition flap techniques after primary pterygium excision as a safe methods regarding efficacy and recurrence prevention. Patients and Methods: Study included 40 eyes of 40 patients with primary nasal pterygia of variable duration coming to outpatient clinics of Ophthalmology Department Al-Azhar University Hospitals between October 2022 to November 2023 classified into two groups; Group (A) 20 eyes for conjunctival autograft and Group (B) 20 eyes for transposition flap technique. Ophthalmic examination is done with Corneal topography before operation then 3 and 6 months postoperative then follow up for 6 months for all eyes. Results: : There was significant high mean value of surgery time ( minutes) as it was 27.88±3.93 in group A and 20.91±2.32 in group B, significant high mean value of flat keratometry (Kf) after 3 and 6 months in both groups and also significant improvement mean value of best corrected visual acuity (BCVA) after 1 , 3 and 6 months postoperative in both groups. Recurrence was 20% in group A and 10% in group B. Conclusion: Conjunctival flap transposition technique is a safe effective method regarding lowering the recurrence rate with improvement of vision and less time consuming during surgery. It is recommended to do more analysis on large sample sizes for advanced cases of pterygia to evaluate these techniques.
