AFFECTING FATORS FOR THE SUCCESS OF MICROPULSE TRANSSCLERAL CYCLOPHOTOCOAGULATION IN GLAUCOMA TREATMENT
Main Article Content
Abstract
Purpose: Evaluating factors related to the success of micropulse transscleral cyclophotocoagulation in treating glaucoma. Patients and Methods: Uncontrolled clinical trial was conducted with glaucoma patients who met one of the following criteria: Patients with uncontrolled IOP despite maximum lowering IOP agents, patients with previously failed surgeries or patients with a high risk of failure for filtering surgery. Treatment results are evaluated at 1 week, 1 month, and 3 months after the first laser session. Patients who do not achieve the desired intraocular pressure may consider a second additional laser at least 1 month after the first session. The rate of success and factors related to the overall success rate are evaluated at 3 month after the first laser session, including age, gender, number of failed surgeries, glaucoma type, onset time of symptom and pre-treatment IOP. Results: 26 eyes of 25 patients with mean age of 50.2 ± 25.7 years were included in the study. Mean preoperative IOP was 37.7 ± 10.5 mmHg which was reduced to 20.6 ± 8.2 mmHg after 3 months (reduction of 45,4%)The success rate between different types of glaucoma is significantly different, the lowest is neovascular glaucoma group and the highest is glaucoma group secondary to inflammation, after trauma, after surgery to treat retinal detachment. Patients with the disease duration less than 1 month have the lowest success rate, followed by the group that have been diagnosed for more than 1 year and the highest success rate was the group which had disease duration from 1 month to 1 year. IOP before treatment has an effect on the success of surgery, the higher the preoperative IOP, the lower the chance of success. Conclusion: Glaucoma type, onset time of symptom and pre-treatment IOP affect the results of micropulse transscleral laser photocoagulation treatment. No association was found between other factors such as age, gender, number of failed surgeries before laser with the overall success of treatment.
