Abstract

Traumatic macular hole due to blunt trauma is a serious condition that reduces visual acuity significantly. The purpose of this study is to describe some early outcomes of surgical treatment for traumatic macula hole due to blunt trauma. This descriptive study was conducted on 33 eyes of 33 patients with macular hole due to blunt trauma. The macular hole is successfully closed in 81.8% of the research group after one or two operations. 57.6% of the cases is of type 1 closure and 24.2% of the cases is of type 2 closure. There are 9 patients (27.3%) who require a second surgery after the first surgery failed to close the macular hole. Among the group of patients requiring second surgeries, the rate of closure is only 44.44%. In which, the rate of type 1 closure after surgery is very low, only about 11.11%. 3 months after surgery, 45.5% of patients has visual acuity more than 20/160. 66.7% of patients reports improvement in their visual function after surgery, 45.5% of the patients improves their vision more than 2 Snellen lines. The central subfield thickness and the ellipsoid zone decrease slightly after surgery,the difference is not statistically significant. In type 2 closure cases,, the basal diameter of the hole post-surgery decreases (p <0.05).
