Iridocycloretraction in closed-angle glaucoma
The British Journal of Ophthalmology
|September 1, 1980
Summary
Iridocycloretraction showed low success rates for glaucoma patients with peripheral anterior synechiae. Success depended on subconjunctival drainage, suggesting it offers no advantage over filtration procedures.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
Background:
- Primary angle-closure glaucoma can lead to peripheral anterior synechiae.
- Previous treatments like peripheral iridectomy may not be sufficient.
Purpose of the Study:
- To analyze the efficacy of iridocycloretraction in patients with extensive peripheral anterior synechiae.
- To evaluate the factors influencing the success of iridocycloretraction.
Main Methods:
- Retrospective analysis of a small patient series undergoing iridocycloretraction between 1969-1976.
- Patients had prior peripheral iridectomy and 360-degree peripheral anterior synechiae.
- Gonioscopy was used to assess synechiae.
Main Results:
- Iridocycloretraction had an unacceptably low success rate.
- Success was correlated with the establishment of subconjunctival drainage.
- No evidence supported the theory of increased aqueous access to the trabecular meshwork.
Conclusions:
- Iridocycloretraction is not a highly effective glaucoma surgery for this patient group.
- Subconjunctival filtration appears to be a more critical factor for success.
- The procedure offers no clear advantages over established filtration techniques.
