Current trends of strabismus surgery in a tertiary hospital.

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 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.

RESULTS

A 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.

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. Good outcomes were obtained in most of the patients at the end of follow-up.
