Long-term follow-up of ocular histoplasmosis treated by argon laser photocoagulation
Abstract:
Sixty-eight eyes in 67 patients with a histoplasmic neovascular membrane treated with Argon laser photocoagulation between 1972 and 1978 are reviewed. Factors affecting visual outcome and causes of visual failure are discussed. Twenty of 68 eyes (nearly 30%) experienced a recurrent or new SRNVM after initially successful treatment. Final evaluation of Argon laser photocoagulation for histoplasmic neovascular membrane must await the outcome of the Macular Photocoagulation Study.
Insights
Argon laser photocoagulation for histoplasmic neovascular membranes showed a nearly 30% recurrence rate. Further evaluation is pending results from the Macular Photocoagulation Study.
Area of Science:
- Ophthalmology
- Retinal Diseases
Background:
- Histoplasmic neovascular membrane is a significant cause of vision loss.
- Argon laser photocoagulation was an early treatment modality.
Purpose of the Study:
- To review visual outcomes and failure causes in patients treated with Argon laser photocoagulation for histoplasmic neovascular membranes.
- To assess the long-term efficacy of this treatment.
Main Methods:
- Retrospective review of 68 eyes from 67 patients treated between 1972 and 1978.
- Analysis of factors influencing visual outcome and causes of visual failure.
Main Results:
- Nearly 30% of treated eyes (20 of 68) experienced recurrent or new subretinal neovascularization (SRNVM) after initial treatment.
- Various factors affecting visual outcome were identified.
Conclusions:
- Argon laser photocoagulation for histoplasmic neovascular membrane has a notable recurrence rate.
- Definitive evaluation of this treatment requires data from the ongoing Macular Photocoagulation Study.
