Abstract
El tratamiento quirúrgico del pterigión es uno de los procedimientos más realizados en la consulta oftalmológica, aunque con frecuencia conlleva molestias y cambios en la agudeza visual. Objetivo: evidenciar si existen cambios en cuanto a agudeza visual y su ametropía, en pacientes diagnosticados con pterigión intervenidos quirúrgicamente, en la ciudad de Quito. Método: se trata de un estudio observacional longitudinal que incluyó 161 pacientes. Se comparó agudeza visual y ametropía antes y 15 días después de la intervención quirúrgica. Resultados: la mayor parte de los pacientes fue de género femenino (n = 118, 73%) tuvo entre 30 y 59 años (n = 127, 79%), presentó pterigión grado III (n = 113, 70%) y fue intervenido del ojo derecho (n = 89, 55%). La agudeza visual de los pacientes mejoró ligeramente. El número de pacientes con agudeza visual 20/20 aumentó de 68 (42%) a 72 (45%). Se observó además una disminución en el número de pacientes con agudeza visual 20/350, 20/200, 20/100, 20/80, 20/60 y 20/50. No hubo cambios en el número de pacientes amétropes que se mantuvo en 69 (43%). Tanto el número de personas con astigmatismo miópico compuesto, como con astigmatismo mixto eje contra la regla disminuyeron de 11 (7%) a 8 (5%) y de 24 (15%) a 16 (10%), respectivamente. Conclusión: tanto la agudeza visual como la ametropía de pacientes con pterigión mejoran ligeramente después de recibir tratamiento quirúrgico.
The surgical treatment of the pterygium is one of the most performed procedures in the ophthalmologic consultation, although it often involves discomfort and changes in visual acuity. Objective: to show if there are changes in visual acuity and its ametropia, in patients diagnosed with surgically intervened pterygium, in the city of Quito. Method: This is a longitudinal observational study that included 161 patients. Visual acuity and ametropia were compared before and 15 days after surgery. Results: most of the patients were female (n = 118, 73%), were between 30 and 59 years old (n = 127, 79%), presented grade III pterygium (n = 113, 70%) and was operated on the right eye (n = 89, 55%). The visual acuity of the patients improved slightly. The number of patients with visual acuity 20/20 increased from 68 (42%) to 72 (45%). There was also a decrease in the number of patients with visual acuity 20/350, 20/200, 20/100, 20/80, 20/60 and 20/50. There were no changes in the number of ametropic patients that remained in 69 (43%). Both the number of people with compound myopic astigmatism, and with mixed astigmatism axis against the rule decreased from 11 (7%) to 8 (5%) and from 24 (15%) to 16 (10%), respectively. Conclusion: both visual acuity and ametropia of patients with pterygium improve slightly after receiving surgical treatment.
