PRATA JR, João Antonio; PEREIRA, Antonio Eduardo and OMI, Carlos Akira. Modified Schocket implant for refractory glaucoma: long-term results. Arq. Bras. Oftalmol. [online]. 2000, vol.63, n.6, pp. 439-443. ISSN 0004-2749. http://dx.doi.org/10.1590/S0004-27492000000600002.
Purpose: To analyze long-term results of modified Schocket implant. Methods: The records of 45 patients (45 surgeries) with at least one year follow-up who received a modified Schocket implant were analyzed. Comparisons were made regarding success rates (final IOP< 22 mmHg), survival time, diag- nosis, initial and final IOP, percentual postoperative intraocular pressure (IOP) reduction and complications. Results: After a mean follow-up of 31.9 ± 19.9 months 28 cases (62.2%) were considered successful. Mean survival time was 38.9 months and success probability around 30 months 0.74. Initial IOP was 37.2 ± 11.3 mmHg and final IOP was 16.3 ± 9.3 mmHg and postoperative IOP reduction was 49.6 ± 32.6%. Survival analysis in the different diagnosis groups (neovascular, congenital, aphakic, postkeratoplasty) did not reveal statistical significance. Conclusion: The results suggest that the modified Schocket implant provides satisfactory long-term control of refrac- tory glaucomas.
