Abstract
The pterygium appears as a fleshy vascular mass that occurs in the interpalpebral fissure, disturbing both the patient because of their unsightly appearance and the surgeon because of their tendency to recur.
This lesion is disfiguring and affects the vision, there this no single definitive method of treatment without different rates of recurrence.
This is a prospective study, was designed in order to evaluate the efficacy of sealing the gap method with amniotic membrane in treatment of primary pterygium as a new method (group B) and we managed the control group by mitomycin C with bare sclera (group A).
This study included 20 eyes of 19 patients in group A and 20 eyes of 19 patients in group B with primary pterygium, of both genders and different age groups.
All patients were subjected to complete history taking and ocular examination.
After excluding collagen vascular disease, previous limbal surgery and ocular surface pathology or infection, under topical anesthesia:
• The patients of group A were treated by excision of pterygium with application of MMC 0.02% for 3 minutes then the bed was lifte with bare sclera.
• The patients of group B were treated by excision of pterygium with identification of the Tenon capsule and closing of the gap between the Tenon capsule and the conjunctiva by 8-0 Vicryl running sutures, amniotic graft was fixed on the bare sclera with interrupted 10/0 nylon sutures.
The average duration of follow up was 16.15 ± 2.50 months in group A and average duration of follow up was 12.75 ± 2.10 in group B.
Delayed epithelization of the cornea (more than 2 weeks) was not seen in any patient in both groups.
