Introduction:

Glaucoma is a disease that affects the eye and at the same time the injury as well as the optic nerve and the retina, related to the increase in intraocular pressure. The detection of adequate treatment helps to offer a better quality of life to the patient.

Objective:

To compare the postoperative intraocular pressure between the trabeculectomy and the Ahmed valve shunt in patients with primary open angle glaucoma of the Central Military Hospital from January 2017 to January 2018.

Material and method:

It is an observational, descriptive and retrospective study, patients diagnosed with glaucoma. his electronic clinical records, using the R program version 3.4.4 (R Foundation for Statistical Computing, Vienna, Austria).

Results:

A total of 100 patients were identified during the study period. The patients present an age between 32 and 93 years. 35% of the patients underwent a trabeculectomy and the remaining 65% underwent a bypass with the Ahmed valve where a greater reduction was observed with the Ahmed valve in patients with higher presurgical pressure.

Conclusions:

We can conclude that the derivation with the Ahmed valve results in better postoperative results, which are observed after the second follow-up visit, so this technique brings better results to the IOP management of patients who require treatment. surgical, a The work is not related to the use of a less invasive technique. Likewise, trabeculectomy better regulates intraocular pressures in those patients who do not have such an increase in IOP.
