[Small gauge vitrectomy in macular surgery for myopic complications]

To investigate the results of small gauge vitrectomy for myopic macular complications.

We reviewed 68 eyes which underwent vitrectomy with various needles (20 G, 27 eyes; sutureless 23 G, 15 eyes; sutured 23 G, 15 eyes; and 25 G, 11 eyes) for myopic macular pathologies. Surgical results and complications were compared.

Mean logMAR after 3 months was 0.85 for 20 G, 0.78 for sutureless 23 G, 0.43 for sutured 23 G, and 0.46 for 25 G (p < 0.05). However, there was no significant difference in visual acuity change between the groups 3 months after surgery (p = 0.21). Mean intraocular pressure 1 day after surgery was significantly different (20 G, 15.0 mmHg; sutureless 23 G, 11.4 mmHg; sutured 23 G, 18.7 mmHg; and 25 G, 14.2 mmHg, p < 0.05), but that significance was lost 7 days after surgery.

The small gauge system produces favorable results in vitrectomy for myopic macular complications, similar to the conventional 20 G system.
