Microdevice for aqueous humor drainage Maldonado Bas - Pförtner

Abstract

RESUMEN Methods:In a prospective study, following the protocol, 16 eyes with refractory glaucoma were included and operated. Intraocular pressure ≤21mmHg with or without additional medication was considered successful. The follow-up was one year. Averages, percentages and their 95% confidence bands were calculated. Analysis of variance for repeated measures was used to compare averages. Results: The average preoperative intraocular pressure was 32.81 mmHg, SD ± 10.94 mmHg in a range of 14 to 50 mmHg. The average post-surgical intraocular pressure at one year was 12.43 mmHg, SD ± 2.85 mmHg in a range of 7 to 19 mmHg. The difference between the pre-and post-surgery average intraocular pressure was 20.38 mmHg. The number of successes was 14 eyes (87.5%, confidence interval (CI) 95% 61.6% -98.6%). The number of failures was two eyes (12.5%, CI 95% 1.43% -38.4%). Conclusions:The results show that the microdevice is successful for the treatment of refractory glaucoma.
