Abstract

PURPOSE
Complications after pars plana vitrectomy are causes that courses heal the wound of sclerotomy site. It is difficult to diagnose abnormal finding at sclerotomy site because of its anatomical location. This study was aimed at assessing changes at the sclerotomy site using ultrasound biomicroscope (UBM) in eyes that underwent pars plana vitrectomy. METHODS: A dynamic in vivo examination using ultrasound biomicroscope (Model P45 UBM plus, Paradigm, U. K.) was performed on 120 sclerotomy sites of 40 eyes of 39 patients after pars plana vitrectomy. Average age was 52.56 years old, average post-operative period was 6.45 +/- 5.71months.
RESULTS
In 120 sclerotomy site, vitreous incarceration, fibrovascular proliferation, scleromalacia was detected using UBM at 30%. Abnormal fidings of proliferative diabetic retinopathy group are more frequent than non-diabetic retinopathy group. After post-vitrectomy hemorrhage patient group is more abnormal finding.
CONCLUSIONS
Ultrasound biomicroscope is a useful tool for the evaluation of sclerotomy site, which is difficult by ordinary method and is an invaluable tool in assessment of the patient before reoperation.
