Performing 25-gauge transconjunctival sutureless vitrectomy for several macular conditions can improve vision and is associated with low rates of both intraoperative and postoperative complications, a retrospective study found.

Fabio Patelli, MD, and colleagues reviewed outcomes for 160 eyes of 150 patients treated with the vitrectomy technique. Indications for surgery included idiopathic macular pucker in 108 eyes, idiopathic macular hole in 24 eyes and tractional diabetic macular edema in 28 eyes. Follow-up averaged 10 months, and all patients had at least 6 months of follow-up, according to the study.

The researchers found that IOP averaged 14 mm Hg at 1 day postop. At 1 month, 69% of patients had gained at least two Snellen lines of visual acuity, which increased to 74% at 3 months, but fell slightly to 67% at 6 months follow-up, according to the study.

There were no intraoperative complications, and only 3% of eyes experienced postop complications, the authors noted.

The study is published in the July/August issue of Retina.
