Summary
Following pterygium removal, a 1-year monitoring period is recommended to detect potential recurrences. Studies indicate a 50% chance of recurrence within 120 days and a 97% chance within 12 months.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Ocular Surface Disease
Background:
- Pterygium is a common ocular surface condition.
- Recurrence after surgical removal is a significant concern.
- Optimal follow-up protocols are needed to manage pterygium recurrence.
Purpose of the Study:
- To determine the necessary follow-up duration after pterygium excision to effectively identify recurrences.
- To establish a timeframe for monitoring patients post-surgery.
Main Methods:
- Retrospective review of patient records with documented pterygium recurrence.
- Analysis of recurrence timing in patients with defined follow-up intervals.
- Survival curve analysis to estimate recurrence probability over time.
Main Results:
- 161 pterygium recurrences were identified.
- The average time to first recurrence was 123 days.
- Survival analysis indicated a 50% recurrence risk within 120 days and 97% within 12 months.
Conclusions:
- A 1-year follow-up period is likely sufficient to identify most pterygium recurrences.
- Early detection of recurrence can inform subsequent management strategies.
