Surgical Outcomes of 27-Gauge Pars PLana Vitrectomy for Symptomatic Vitreous Floaters

الملخص EN

Purpose.

To report the surgical outcomes of 27-gauge pars plana vitrectomy (PPV) for symptomatic vitreous floaters.

Methods.

47 eyes of 47 patients (39 males, 83.0%) with symptomatic vitreous floaters who underwent 27-gauge PPV and followed up for more than 6 months were included.

The mean age was 34.7 ± 13.5 years.

Results.

No operative complication occurred.

At first day postoperatively, the intraocular pressure (IOP) was significantly lower than that at other time points (8.6 ± 2.7 mmHg, p<0.001).

28 (59.6%) eyes had transient hypotony (IOP < 8 mmHg).

All were recovered within 1 week postoperatively.

The BCVA of 41 eyes (41/47, 87.2%) remained unchanged or improved.

Postoperative complications occurred in two eyes: one (2.1%) had endophthalmitis and one (2.1%) had retinal detachment.

No clinical significant cataract was observed in the 42 postoperative phakic eyes.

91.5% of the patients were satisfied with the surgery outcome.

Besides, 91.3% of the patients felt that the floaters were removed completely or only had an acceptable residual.

Conclusion.

Visual acuity of most patients remained unchanged or improved following 27-gague pars plana vitrectomy for symptomatic vitreous floaters, resulting in high patient satisfaction.

However, this treatment should be performed with great caution since severe postoperative complications may still occur.

This trial is registered with NCT03049163.
