    Ultrasound-assisted vitrectomy for late stage infectious endophthalmitis
    (2011) Kaykçoǧlu Ö.; Emre S.; Seymenoǧlu G.
    We described an ultrasound-assisted technique of pars plana vitrectomy in endophthalmitis cases with visualization problems of the retina related to the loss of ocular media clarity.We performed pars plana vitrectomy, assisted with a B-mode ultrasonography, on 5 eyes of 5 patients who were referred for late-stage postcataract endophthalmitis. After the implantation of a 6.0-mm infusion port and creation of another pars plana sclerostomy, a 20-gauge vitrectomy tip was visualized in the midvitreus cavity. Core vitrectomy was performed followed by intravitreal antibiotic injection at the end of the surgery without complication in all cases.The study group of 5 patients had a mean age of 73.6 ± 7.9 years. Preoperative visual acuity was light perception positive in 2 eyes and light perception negative in 3 eyes. We obtained satisfactory cosmetic results in all patients, controlled intraocular infection, and prevented evisceration; however, there was no change in visual acuity after surgery.In this preliminary study, we obtained acceptable results with ultrasound-assisted vitrectomy, which may help retinal surgeons to operate on cases with ocular media opacity.

    Efficacy of selective laser trabeculoplasty in phakic and pseudophakic eyes
    (Lippincott Williams and Wilkins, 2015) Seymenoʇlu G.; Baser E.F.
    Purpose: To compare the efficacy of selective laser trabeculoplasty (SLT) in phakic and pseudophakic eyes in open-angle glaucoma and ocular hypertension. Materials and Methods: Charts of 28 pseudophakic eyes and 60 phakic eyes that underwent 360-degree SLT were retrospectively reviewed. Patients were examined at 1, 3, 6, and 12 months. Treatment success was defined as ≥20% intraocular pressure (IOP) reduction, with no additional medications, laser, or glaucoma surgery. Mean IOP change, mean percentage of IOP reduction, and success rates for phakic and pseudophakic eyes were compared. Results: Mean percentage of IOP reduction post-SLT at 1-, 3-, 6-, and 12-month visits were 21.4%, 25.8%, 24.8%, and 23.7%, respectively, in the pseudophakic group and 22.8%, 25.0%, 25.7%, and 21.2%, respectively, in the phakic group. Success rates ranged between 60% and 64% in the pseudophakic group and between 58% and 73% in the phakic group. No statistically significant differences in IOP change, percentage of IOP reduction, and success rate were seen between the groups at any of the post-SLT visits (P>0.05). Conclusions: Application of 360-degree SLT seems to be an efficient and safe treatment option for the management of phakic and pseudophakic open-angle glaucoma and ocular hypertension.
