High osmolarity effect of intravitreal plasmin enzyme on rabbit retina.

We conducted a study of the effect of intravitreal plasmin on retinal thickness in rabbits. Forty rabbit eyes were injected with 0.4, 1, 2, and 5 IU of plasmin (8 eyes/group).

Twenty five-gauge sutureless vitrectomy versus 20-gauge vitrectomy in epiretinal membrane surgery.

Purpose: To compare visual outcomes, intraoperative and postoperative complications of 25-gauge transconjunctival sutureless vitrectomy (25-G TSV) versus conventional 20-gauge vitrectomy in epiretinal membrane (ERM) surgery.

Methods: A retrospective comparative study was conducted on 200 eyes with idiopathic ERM who underwent either primary 20-gauge vitrectomy (n=95) or 25-G TSV (n=105) with 6 months follow up. The following parameters were collected and compared: age, gender, best corrected visual acuity (BCVA), intraocular pressure (IOP), postoperative anterior chamber inflammation, intraoperative and postoperative complications.
