Purpose: To report the effects of a preplaced suture on postoperative transient hypotony after pars plana silicone oil (SO) removal.
Methods: We retrospectively reviewed the medical records of patients who underwent pars plana silicone oil removal between January 2000 and June 2011. The patients were divided into two groups: the preplaced suture group before SO removal (group 1) and the no preplaced suture group (group 2). The changes of intraocular pressure (IOP) after surgery were recorded. Patients who underwent tamponade of gas or air were excluded. Transient postoperative hypotony was defined as an IOP less than 6 mmHg, or less than 9 mmHg within 1 week after surgery.
Results: 118 eyes and 27 eyes were included in group 1 and group 2, respectively. The number of eyes with transient hypotony according to an IOP less than 6 mmHg was 5 eyes in group 1 (4.23%) and 3 eyes in group 2 (11.11%). However, the difference was not statistically significant (Fisher’s exact test, p = 0.168). The number of eyes with transient hypotony according to an IOP less than 9 mmHg was 13 eyes in group 1 (11.01%) and 7 eyes in group 2 (11.11%), and the difference was statistically significant (Chi-square p = 0.038).
Conclusions: A preplaced suture before SO removal could prevent the incidence of postoperative transient hypotony.
