Summary
Flat iris tumors spreading into the anterior chamber angle were treated with argon laser photocoagulation. This treatment successfully regressed tumor growth and led to good patient outcomes without surgery.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Flat pigmentary iris tumors present a diagnostic and therapeutic challenge.
- Limited treatment options exist when histopathological diagnosis is unobtainable due to patient consent.
Observation:
- Four cases of flat pigmentary iris tumors, with extension into the anterior chamber angle in three patients, were observed.
- Patient refusal of surgical intervention precluded definitive histopathological diagnosis.
Findings:
- Multi-stage argon laser photocoagulation was employed as the primary treatment modality.
- The laser treatment resulted in cicatrization and atrophy of the tumor tissue and iris.
- Tumor growth regression was observed during a 2-5 year follow-up period, with all patients maintaining good condition.
Implications:
- Argon laser photocoagulation offers a viable, non-surgical treatment option for flat iris pigmentary tumors.
- This approach can achieve tumor regression and preserve ocular health in select cases.
- Further research into conservative management of iris tumors is warranted.
