Abstract
Pterygium, non-involuntary corneal degeneration, is an inflammatory and proliferative alteration of the ocular surface with thickening and elastotic degeneration of the conjunctiva. Exposure to ultraviolet solar radiation, heat, dust and viral agents participate in its evolution. Objective: to describe the results of pterygium surgery at the San José Hospital in Bogotá DC. Method: case series of all patients with this diagnosis operated between January 2010 and December 2011. Results: 176 stories were reviewed and 113 eyes were included. The most frequent complications were corneal del 7.9%, reproduction 5% and retraction of plasty 3.5%, identified in the first three months postoperatively. The reproduction frequency was higher in the cases of pterygium reproduced (33%), compared to the primary 4.4%. Conclusion: despite the known side effects of mitomycin, those who used it in the postoperative period in low doses did not present adverse effects and its use was safe. Given the low percentage of reproduction in this study, it is recommended that in the resection of extensive or reproduced pterigios, the use of amniotic membrane be considered.
