Summary
Beta radiation, specifically strontium 90, effectively prevents pterygium surgery recurrences. Postoperative beta therapy using strontium 90 applicators showed minimal complications in over 200 cases, with no observed radiation cataracts.
Area of Science:
- Ophthalmology
- Radiation Oncology
Background:
- Pterygium surgery aims to remove eye tissue growth.
- Recurrence after pterygium surgery is a significant clinical challenge.
- Beta radiation is explored as an adjunct therapy to reduce recurrence rates.
Purpose of the Study:
- To evaluate the efficacy of beta radiation in preventing pterygium recurrence post-surgery.
- To present an effective surgical regimen incorporating beta radiation.
- To discuss the mechanism of beta ray therapy and its safety profile.
Main Methods:
- Surgical excision of pterygium.
- Postoperative application of beta radiation using a strontium 90 applicator.
- Detailed surgical steps focused on preventing revascularization of the operative site.
Main Results:
- Beta radiation significantly decreased pterygium recurrence rates.
- Over 200 cases treated with strontium 90 showed few complications.
- No instances of radiation cataract were observed in the study cohort.
Conclusions:
- Postoperative beta radiation with strontium 90 is a beneficial adjunct to pterygium surgery.
- The presented surgical technique, combined with beta radiation, effectively minimizes recurrence.
- Strontium 90 beta therapy is a safe and effective treatment for reducing pterygium regrowth.
