Purpose
To analyze the epidemiological profile of patients who were operated of pterygium in Eyes Institute of Goiânia, analyze the post-operative results according to the chosen surgical technique and evaluate the refractive changes before and after the excision of pterygium.
Methods
This prospective clinical trial included 51 patients (38 eyes), who underwent pterygium surgery performed by a PGY-1 resident of Eyes Institute of Goiânia from February 2013 to August 2013.
Results
There were 18 males (35,3%) and 33 females (64,7%) of 51 patients with a mean age of 60,71 years (SD 9,93 years). 54,9% of patients had pterygium in the right eye and 45,1% in the left eye. 94,1% of pacients had nasal pterygium and 3,9% had temporal pterygium. 11,8% of pacients had pterygium grade I, 47,1% had grade II, 33,3% had grade III and 7,8% had grade IV. 52,9% of patients had a family history of pterygium. 12,0% of patients had pterygium in both eyes. Concerning about the surgical techniques, 54,9% was conjunctival transplantation, 39,2% was conjuctival flap reconstruction and 5,9% was conjunctival approach technique. 11,4% of patients had with-the-rule astigmatism and 20,5% against-the-rule astigmatism before the surgery. After the surgery, 20,5% with-the-rule astigmatism and 13,3% was against-the-rule astigmatism. There was a significant difference in astigmatism before and after the surgery at different intervals (P < 0.05).
Conclusions
This study is important to know about the Epidemiological profile of Brazilian patients with pterygium and to conclude that there was a statistically significant decrease in astigmatism with pterygium surgery.
