Abstract
ObjectiveTo study the outcomes of minimally invasive strabismus surgery (MISS) for treating horizontal deviation. MethodCase Series of the first 26 consecutive patients operated on using the MISS technique in our hospital from February 2010 to March 2014. ResultsA total of 40 eyes were included: 26 patients (mean age: 7.7 years old±4.9); 34.61%: male. A total of 43 muscles were operated on: 20 medial, and 23 lateral recti; 28 recessions (range: 3–7.5mm), 6 resections (6–7mm), and 9 plications (6.5–7.5mm) were performed. No significant difference was found (p>0.05) for visual acuity at postoperative day 1, and 6 months after surgery. A mild hyperaemia was observed in 29.27%, moderate in 48.78%, and severe in 21.95% at postoperative day 1 and in 63.41%, 31.70% and 4.87%, respectively, at 4 days after surgery. The complications observed were 4 intraoperative conjunctival hemorrhages, 1 scleral perforation, and 2 Tenon's prolapses. A conversion from MISS to a fornix approach was necessary in 1 patient because of bad visualization. The operating time range decreased from 30 to 15min. ConclusionsThe MISS technique has obtained good results in horizontal strabismus surgery. The conjunctival inflammation was mild in most of the cases at postoperative day 4. The visual acuity was stable during follow-up, and operating time decreased after a 4-year learning curve.
