Current trends of strabismus surgery in a tertiary hospital

Abstract

Abstract Objective to analyze the strabismus surgeries and the outcomes during a year and a half in a tertiary hospital. Material and methods a retrospective study of patients who underwent strabismus surgery. The mean age, sex, diagnosis, diplopia, surgery, anesthesia, adjustable sutures, results, reoperations and follow-time from surgery were analyzed. A good outcome was considered when the final horizontal deviation was less than 10 prism diopters (pd) and the vertical deviation, less than 5 pd without diplopia. Results a total of 153 cases were operated on, mean age: 43.14 ± 25.58 years (61.4%: women). The 74.5% was ≥18 years (33.33%≥ 60). The 51% had diplopia. 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 the 19.7% and topical anesthesia in 65.4%. The 79.2% had good outcomes 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 = 0.012) and the oblique superior surgery (P = 0.017) were associated to a bad result. Conclusion the 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. The good outcomes were obtained in most of the patients at the end of follow-up.
