Summary
Amniotic membrane transplantation (AMT) significantly reduced pterygium recurrence compared to the bare sclera technique. This pilot study suggests AMT is a safe and effective treatment option for primary pterygium.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Regenerative Medicine
Background:
- Pterygium is a common ocular condition.
- Recurrence after surgical excision remains a challenge.
- Bare sclera technique is a traditional method for pterygium excision.
Purpose of the Study:
- To compare the efficacy of bare sclera technique versus amniotic membrane transplantation (AMT) for primary pterygium excision.
- To evaluate the recurrence rates of pterygium following these two surgical methods.
Main Methods:
- A pilot study involving 70 patients with primary pterygium.
- Patients were divided into two groups: bare sclera excision (Group I) and excision with AMT (Group II).
- Recurrence rates were monitored for 6 months and compared using chi-square tests.
Main Results:
- Pterygium recurrence was observed in 37.5% of patients in the bare sclera group (12/32).
- Recurrence was significantly lower in the AMT group, with 12.9% of patients experiencing recurrence (4/31).
- The difference in recurrence rates between the groups was statistically significant (p = 0.025).
Conclusions:
- Amniotic membrane transplantation (AMT) following pterygium excision is a safe and effective procedure.
- AMT demonstrates a lower pterygium recurrence rate at 6 months compared to the bare sclera technique.
- AMT offers a promising alternative for managing primary pterygium with improved outcomes.
