    Choroidal neovascularization secondary to ocular penetration during retrobulbar anesthesia and its treatment
    (Medknow Publications, 2017) Dikci S.; Yilmaz T.; Gök Z.; Demirel S.; Genç O.
    Retrobulbar anesthesia is still used before ocular surgery; however, it has various complications including ocular penetration. The penetration/perforation of the globe can cause complications such as endophthalmitis, retinal detachment, and scotoma. Choroidal neovascularization (CNV) is rarely seen, following choroidal rupture in penetrating eye injuries. Here, we present a patient who underwent a pars plana vitrectomy for vitreous hemorrhage secondary to ocular penetration during a retrobulbar injection for cataract surgery. This patient later developed CNV at the penetration site during follow-up. Physicians should remember that CNV can occur as an unusual late complication of ocular penetration during retrobulbar anesthesia. © 2017 Oman Ophthalmic Society | Published by Wolters Kluwer - Medknow.

    Clinical Results After Removing Silicone Oil in Patients Underwent Pars Plana Vitrectomy and Silicone Oil Endotamponade Due to Diabetic Tractional Retinal Detachment
    (Gazi Eye Foundation, 2019) Dikci S.; Yilmaz T.; Ulucan P.B.
    Purpose: To evaluate the complications encountered in the postoperative period as well as anatomic results following the removal of silicone oil tamponade in patients undergoing 23 gauge pars plana vitrectomy (PPV) and silicone oil endotamponade for diabetic tractional retinal detachment. Materials and methods: Fifty-nine eyes of 54 patients who underwent surgery for diabetic tractional RD between January 2015 and April 2016 in our clinic were included in the study. The files of the cases were examined retrospectively. Age, gender, duration of silicone oil endotamponade, best corrected visual acuity (BCVA), intraocular pressure (IOP), redetachment rate and other postoperative complications were evaluated. Results: 35 of the patients were female (64.8%) and 19 were male (35.2%). The mean age was 59.1 ± 10.2 (29-80) years. The preoperative mean BCVA was 0.06 ± 6.6 (0.03-0.4), while the postoperative mean BCVA was 0.10 ± 13.3 (0.03-0.7). The preoperative and postoperative mean IOP were 16.3 ± 6.04 and 14.3 ± 4.1 mmHg, respectively. The mean duration of silicone oil endotamponade was 6.8 ± 4.01 (2-24) months. Cataract surgery was performed in 31 (52.5%) patients as removing silicone oil endotamponade. Postoperative complications were transient severe hypotony in one eye (1.7%), transient hypertony in three eyes (5.08%), vitreous hemorrhage requiring surgery, hyphema and hypopyon in one eye (1.7%) and redetachment in four eyes (6.8%). Conclusion: In patients who underwent pars plana vitrectomy and silicone oil endotamponade due to diabetic tractional retinal detachment, ocular hypotonia or hypertonia and vitreous hemorrhage may rarely develop, besides retinal redetachment, following removal of silicone oil endotamponade.. © 2019 Gazi Eye Foundation.
