Swept-source OCT protocol may limit prone position time after macular hole surgery

A swept-source OCT imaging protocol helped reduce the prone position time of patients undergoing vitrectomy without reopening the macular hole, according to a study.
Compared with conventional fundus examinations by indirect ophthalmoscopy, patients imaged with SS-OCT experienced statistically significantly less time in the prone position before macular hole closure. Researchers studied 129 eyes of 125 consecutive patients with macular hole who had undergone vitrectomy. The prone position was halted by a surgeon’s decision in 69 eyes of 66 patients in the conventional group, while it was halted after SS-OCT detected closure in 60 eyes of 59 patients.
The macular hole was closed in 58 eyes (97%) in the SS-OCT group and in 69 eyes (100%) in the conventional group; the difference was not statistically significant. The two eyes in the SS-OCT group that did not have closure received additional gas injection and then experienced hole closure.
The average number of days in the prone position in the SS-OCT group was 1.8 days, significantly shorter compared with 8.4 days in the prone position in the conventional group (P < .0001).
There were no differences in surgical outcomes between the two patient groups. – by Robert Linnehan
