Item Subfoveal perfluoocarbon liquid retention after retina detachment surgery; [Retina Dekolman Cerrahisi Sonrasi Subfoveal Perflorokarbon](Gazi Eye Foundation, 2014) Kayikçioʇlu Ö.; Bilgin S.This study presents two cases that had subfoveal perfluorocarbon liquid (PFCL) after rhegmatogenous retinal detachment surgery. The first case was a 65-year-old pseudophakic male patient. The superior temporal retinal tear and a bullous retinal detachment that reached the macula border was observed in the right eye. The patient underwent 23 G pars plana vitrectomy (PPV). Intravitreal perfluorocarbon liquid was used to reattach the retina and perform laser retinopexy around the tear. The surgical procedure was ended by PFCL-air and air-silicone exchange. In the first month, subfoveal PFCL droplets were observed in the control examination. The patient, who was reoperated, was injected with an infusion liquid using a 38 G cannula from the perifoveal area; liquid and decalin droplets were re-aspired using a flute cannula. There were no PFCL droplets in the control examination. Visual acuity, which was 0.2 pre-operatively, increased to 0.3 post-operatively, but the patient complained of metamorphopsia . The second case was a 66-year-old male patient. There was a retinal tear in the right eye at the 5 o'clock position, and a retinal detachment in the lower half. The patient underwent a 23 G PPV operation. Intravitreal perfluorocarbon liquid was used to reattach the retina. First silicone and then heavy silicone oil was used in two subsequent surgeries. In the final control examination performed after silicone removal, PFCL was detected in the subfoveal area. The patient was followed up without surgery, had a visual acuity of 0.2, and a central scotoma was present in the superior temporal fixation center of the visual field.Item Conjunctival granuloma in a patient who had combined classical retinal detachment surgery and pars plana vitrectomy; [Klasik Retina dekolman cerrahisi ve pars plana vitrektomi kombine edilen hastada gelişen konjonktival granülom](Gazi Eye Foundation, 2015) Bilgin S.; Kayikçioğlu Ö.R.Pyogenic granuloma is a benign proliferative vascular tumor that may be seen at areas of intense vascularization due to chronic inflammatory reaction. It also can be seen due to surgical trauma and materials used during operation. For treatment, removal of surgical material and surgical excision of granuloma are mostly sufficient. In this paper, a patient with conjunctival granuloma following combined classical retinal detachment surgery and pars plana vitrectomy is presented. © 2015 Gazi Eye Foundation.

Materials and Methods: This study included cases who received surgical treatment due to primary rhegmatogenous retinal detachment in our clinic, between March 2003 and April 2014. According to surgery techniques, the cases were evaluated retrospectively and divided into two groups as SB and PPV. The groups were evaluated for anatomical and functional success and complications. Results: Single-surgery anatomic success was achieved in 48 of 52 (94%) eyes that underwent PPV and in 42 of 52 (80%) eyes that underwent SB (p=0.085). The mean VA improvement in the PPV group was significantly better than in the SB group (PPV, 1.196 logMAR (11 standard ETDRS line); SB, 0.155 logMAR (1.5 standard ETRDS line)) (p<0.001). Subfoveal perfluorocarbon liquid retention was observed in two eyes in the PPV group. Conjunctival pyogenic granuloma occured in one eye in the SB group. Endophthalmitis was not observed in any patient in both groups . Conclusion: Although both surgical methods seems to be efficient treatment modalities for primary regmatogenous retinal detachment, better anatomical outcomes were achieved with PPV. In addition, complication types are different due to different surgical procedures and adjunctive tamponade, scleral buckling elements and perfluorocarbon use. © 2016 Gazi Eye Foundation.

Method: Retrospective case report. Results: A 65-year-old woman was presented to us with a history of bilateral gradual vision deterioration and nyctalopia for three months'duration. She was previously diagnosed to have a neuroendocrine tumor in 2008 and received a multitude of systemic therapies including surgical resection, chemotherapy and radiotherapy. On examination, her best-corrected visual acuity was 0.3 with normal anterior segment and normal looking posterior pole OU. Bilateral peripheral consantric narrowing was present at the visual field test and depressed scotopic responses was revealed at the ERG test. The diagnosis was cancer-associated retinopathy. Unfortunately, she died in three months time due to multiple metastasis. Conclusion: Cancer-associated retinopathy should be considered in differential diagnosis of patients presenting with progressive vision loss and nyctalopia. © 2017 Gazi Eye Foundation.

Materials and Methods: FA images, obtained with Spectralis were retrospectively analysed. The images of the DRP and BRVO cases were enrolled in the study. The images were exported to the Microsoft Paint program and the circles pointing to 7-field images were digitally mounted on the wide-field images. ETDRS-7 field and wide field images were compared for distribution of ischemia and neovascularization (NV). Ischaemic areas were classified as mild, moderate or severe ischemia according to the area of one circle of the 7-field image. Results: A total of 136 images of DRP and seven images of BRVO cases were enrolled. 24 images were proliferative DRP while 112 images were nonproliferative DRP according to Spectralis images. ETDRS-7 field images failed to detect severe ischemia in 32 eyes (23.52%), moderate ischemia in 16 eyes (11,76%) and mild ischemia in 36 eyes (26,47%). Also 7-field images could not detect NV in three eyes (11,76%). Also standard 7-field images could not detect severe ischemia in two eyes with BRVO. Conclusion: Ultra-wide field FA images may provide additional informations compared to the ETDRS 7-field images in evaluating retinal vascular diseases which may cause increasing the grading and severity of the diseases. © 2019 Gazi Eye Foundation.

The treatment of the retinal detachment which was considered to originate from choroidal coloboma was lens aspiration, IOL implantation followed by 23 G Pars plana vitrectomy. Following core vitrectomy and perfluorocarbon injection, retinal dialysis was observed in the lower nasal area during the peripheral vitreous shaving using indentation. Our patient was only then correctly diagnosed as retinal detachment secondary to retinal dialysis was treated with PPV-endolaser and 16% C3F8 gas injection and in the post-operative period, the retina attached. Retinal dialysis was encountered in the patient without history of trauma in whom we thought retinal detachment was due to the subvisible tears in the coloboma. Peripheral retina and vitreous base should be examined in detail in all of our patients even if there are apparent causes for detachment as choroidal coloboma. © 2020 Gazi Eye Foundation.

Visual acuity of a 26 year-old woman complaining about visual loss in the left eye and fuzziness in both eyes was 0.05 in the right eye and 0.5 in the left eye. Anterior segment examination was normal in the right eye and anterior chamber had 2+cells in the left eye. In the fundus examination of the right eye, diffuse chorioretinal atrophy and atrophy in macula were observed. In the examination of the left eye, macular nasal elevation and retinal pigment irregularity was detected. OCT showed atrophy of the fovea and subretinal fi brosis in the right eye , foveal nasal elevation and fi brosis in the left eye. In FFA, scar areas were observed in the right eye retina and there was, an active focus tbc granuloma and three scar areas in upper temporal of the left eye. The patient was followed-up under anti-Tbc treatment with the advice of pneumotologist and also topical cyclopegia and steroid treatment. The patient's visual acuity peaked in the left eye after a 12-month treatment. In the follow-ups, foci were observed in the posterior areas of the left eye. During the follow-up period, fresh foci were seen in adjacent areas of the posterior in the left eye in the second year. The patient is still under follow-up with anti-TBc treatment. Tuberculosis uveitis and choroidal granulomas are serious diseases which require long and careful follow-up. © 2021 Gazi Eye Foundation.

Materials and Methods: We operated on eight patients who were treated for acute central retinal artery occlusion without visible emboli in our clinic. We started emergency medical treatment following diagnosis which was unsuccessfull. Afterwards, the patient had PPV in six cases and PPV- trabeculectomy in two cases. During the operation we applied intraoperative hypotonia for ten minutes and we tried to restore retinal circulation with fluid turbulance on optic nerve head. While visual acuity remained at the basal level in five patients (hand movement positive), slight increase was observed in three patients (preop P (-), 20 cmFC, 2 mFC,; postop 30 cmFC, 30 cmFC, 0.1 respectively). Discussion and Conclusion: Primary pars plana vitrectomy and surgical hypotonia may be an early treatment option for central retinal artery occlusion without visible emboli, which should be evaluated in large scale studies. © 2023 Gazi Eye Foundation.
