PURPOSE:

To evaluate the safety and efficacy of modified (two port) multiport illumination system (MIS) for a variety of vitreoretinal surgeries.

METHODS:

We performed a retrospectively reviewed a 108 consecutive patients (64 women, 44 men) who underwent pars plana vitrectomy by modified MIS for following conditions: diabetic tractional detachment with/without vitreous hemorrhage (n=47), rhegmatogenous retinal detachment (n=49), diabetic macular edema (n=7), foreign body (n=1), silicone exchange
with/without phacoemulsification surgery (n=4). All procedures were performed by the MIS. Only two port vitrectomy by the MIS without any additional port entry was performed.

RESULTS:

Mean follow-up was 6 months (range 1 to 13 months). Visual acuity was stabilized in 62 eyes (57.4%) of 108 eyes, improved in 38 eyes (35.1%), and reduced in 8 eyes (7.40%). No intraoperative complications occurred. Postoperative complications were hypotony in 12 eyes, rehemorrhage in 8 eyes, and choroidal detachment in 1 eye. Eight cases required
conversion to standart 3 port sclerotomy. Sclerotomy sutures were required for enlarged sclerotomies in all cases. Mean overallĀ  preoperative and postoperative intraocular pressure was 16.9 mm Hg and 15.8 mm Hg, respectively.

CONCLUSION:

Despite some limitations two port modified MIS is a good, comfortable and safe option for posterior segment surgeries.
