    Bilateral non-arteritic anterior ischemic optic neuropathy following second-trimester spontaneous abortion-related haemorrhage
    (Elsevier Sci Ltd, 2012) Onaran, Zafer; Tan, Funda Uysal; Yilmazbas, Pelin; Onaran, Yüksel
    Bilateral anterior ischemic optic neuropathy is a rare complication of massive haemorrhage and related hypotension and anaemia in young individuals. We report a 34-year-old woman with bilateral non-arteritic ischemic optic neuropathy (NAION) after a massive spontaneous abortion-related haemorrhage who presented with sudden painless visual loss in her left eye. Visual acuity was 20/20 in the right eye with only hand motion discernible in the left eye. There was a left relative afferent papillary defect (RAPD). Fundus examination revealed bilateral swollen, hyperaemic optic discs and nerve fiber layer haemorrhages. Brain MRI and magnetic resonance venography were normal. The diagnosis of bilateral NAION was made and intravenous pulse corticosteroid therapy (1000 mg/day) was administered for three days. On the sixth clay, optic disc oedema regressed bilaterally and on the third week, the visual acuity improved to 20/80 in the left eye. The visual field showed only a small spared area in the nasal region, and persistent RAPD was present. After two months, fundus examination showed a small and crowded optic disc on the right and a pale optic disc on the left. Severe acute haemorrhage is an important risk factor for NAION in healthy young individuals. In addition to correction of hypotension and anaemia, intravenous high dose corticosteroid might be beneficial for treatment. (C) 2012 Elsevier Ltd. All rights reserved.

    Endoscopic Management Of Subperiosteal Orbital Abscess As Sinusitis Complication; A Case Report
    (Turkish Ophthalmological Soc, 2009) Onaran, Zafer; Yilmazbas, Pelin; Arikan, Osman Kursat; Ergin, Ahmet
    Purpose: We aimed to emphasize the diagnosis and treatment of subperiosteal orbital abscess secondary to acute sinusitis. Method: A 9-year-old patient referred to our clinic complaining pain and swelling in his left eye for three days. There were proptosis, chemosis, eyelid edema and ocular motility restriction on examination, therefore magnetic resonance imaging was performed with the diagnosis of orbital cellulites and left paranasal sinusitis and subperiosteal orbital abscess were reported. Result: As the medical management failed the patient was successfully treated with endoscopic sinus surgery and abscess drainage. Conclusion: Endoscopic approach should be considered as the first choice when surgery is indicated in the subperiosteal orbital abscess cases.

    Refractive astigmatism in eyes with pseudoexfoliation syndrome
    (Wichtig Editore, 2009) Ornek, Kemal; Gullu, Reyhan; Yilmazbas, Pelin
    PURPOSE. To determine the effect of pseudoexfoliation syndrome on ocular refractive astigmatism. METHODS. One hundred eyes of 100 patients with pseudoexfoliation syndrome and 100 eyes of 100 age- and sex-matched control subjects were included in the study. Refractive astigmatism was measured prior to ocular examination performing cycloplegic autorefractive measures using an autorefractokeratometer (Charops, MRK3100). RESULTS. All patients in the study and control group had myopic astigmatism. Refractive and ocular residual astigmatism were found to be significantly higher in the pseudoexfoliation syndrome group in comparison to the control group (p<0.05). The mean keratometry reading was significantly steeper in the study group than in the control eyes. CONCLUSIONS. Significant refractive and ocular residual astigmatism were found in pseudoexfoliation syndrome. (Eur J Ophthalmol 2009; 19: 873-5)

    Two Rare Forms of Slit Lacrimal Canaliculus; Self-Inflicted and Congenital
    (Turkish Ophthalmological Soc, 2010) Onaran, Zafer; Yazici, Bulent; Yilmazbas, Pelin
    Lacrimal punctal or canalicular slitting is usually seen as a complication of bicanalicular silicon intubation and, except that, is rarely encountered. Here we report two cases of slit canaliculus due to self-inflicted trauma and congenital developmental anomaly and discuss the relevant literature. Twenty-five-year-old male patient with psychotic disorder presented with bilateral upper canalicular slitting and lower punctal stenosis as well as symblepharon and restrictive ocular myopathy due to selfmutilation with sharp objects. The other patient was a 70-year-old female who had a mucosal opening from the punctum to the medial canthus in all four canaliculi. Although slit canaliculus constitute a significant anatomic deformity, it did not cause lacrimal complaints in both patients.
