Tendencias actuales de la cirugía de estrabismo en un hospital terciario

Abstract

ObjectiveTo analyze the strabismus surgeries and the outcomes during a year and a half in a tertiary hospital. Material and methodsA retrospective study of patients who underwent strabismus surgery. The mean age, sex, diagnosis, diplopia, surgery, anesthesia, adjustable sutures, results, reoperations and follow up time from surgery were analyzed. A good outcome was considered when the final horizontal deviation was less than 10prism diopters (pd) and the vertical deviation less than 5pd without diplopia. ResultsA total of 153 cases were operated on, mean age: 43.14 ±25.58years (61.4%: women). 74.5% of patients were ≥18years (33.33% ≥60). Diplopia was present in 51% of patients. The most frequent deviation was horizontal: 83.6%. The most frequent diagnosis was cranial nerve palsies: 32% (VI nerve: 12.4%), restrictive strabismus: 7.2%, and the aged related distance esotropia: 6.5%. Adjustable sutures were used in 19.7% of cases and topical anesthesia in 65.4%. Good outcomes was present in 79.2% of cases at the end of follow-up. Reoperations were needed in 25.5%. Follow-up evolution time was 11.87 months ±6.5. The sex female (P=.012) and the oblique superior surgery (P=.017) were associated with bad outcome. ConclusionThe adult strabismus surgery was three times more frequent than the children strabismus surgery. The third of the adults that were operated on were ≥60 years. The cranial nerve palsies were the most frequent diagnosis. Adjustable sutures were rarely used. Good outcomes were obtained in most of the patients at the end of follow-up.
