    Risk Factors of Peroperative Suprachoroidal Haemorrhage
    Kayikiçoglu, OR; Emre, S; Demiray, B; Baser, E; Kurt, E; Ilker, SS
    Purpose: The aim of this study is to evaluate peroperative risk factors of patients who had suprachoroidal haemorrhage during different types of intraocular surgeries. Material and Method: We retrospectively evaluated general risk factors of five patients who had suprachoroidal haemorrhage. For that purpose, we reviewed the preoperative systemic and ophthalmologic recordings, performed procedures, and complications during and after the surgery from patients' files. Results: Suprachoroidal haemorrhage developed during cataract surgery with phacoemulsification in three cases, in a combined glaucoma and cataract surgery in one, and pars plana vitrectomy in one case. As surgical risk factor, one case had posterior capsular rupture, one hypermature cataract and one previous retinal detachment surgery. In the case with age-related macular degeneration and intravitreal heamorrhage, suprachoroidal haemorrhage arose during pars plana vitrectomy. Only the patient who underwent combined mini-nuc and trabeculectomy procedure had expulsive haemorrhage. As systemic risk factors all the patients were elderly, systemic hypertension, pain during the surgery, anxiety related to panic atac and prostate hypertrophy were other detected risk factors. Discussion: According to our clinical experiences, detected risk factors in our patients were in concordance with literature data. In addition to this, despite the smaller incision size trend in ophthalmic surgery, suprachoroidal haemorrhage is still an important potential complication, particularly in patients who had previous ocular surgeries or who had associated ophthalmologic or systemic risk factors.

    MRI Findings of Globe and Optic Nerves in Tilted Disk Syndrome
    Orguc, S; Toprak, AB; Demiray, B; Tarhan, S; Güler, C
    We assessed the anatomical variations of the globe and optic nerve in tilted disk (TD) syndrome using magnetic resonance imaging (MRI) findings and compared them with a control group. Eleven patients diagnosed with TD syndrome during eye examination were referred for MRI of the sella and chiasm to exclude intracranial mass lesions. The shape of the globe, the chiasmal angle, the insertion angles of the optic nerve in axial and parasagittal planes determined by lines parallel to the optic nerve and tangent to the globe in TD syndrome were compared with a control group consisting of 53 cases. Gender ratios were 7/4 (F/M) for the TD group and 35/18 for the control group (p>0.05). The insertion angle of the optic disk to the globe was wider in the temporal quadrant (p<0.05) and narrower in the nasal quadrant (p<0.05) in TD syndrome than in the control group. There was no significant difference in the superior and inferior insertion angles between the groups. The anterior-posterior (AP) diameter of the globe was significantly longer in patients with TD (p<0.05). There was no significant difference between the optic chiasm angles. The relationships of the optic disk and the globe were significantly different in patients with TD syndrome in comparison to the control group. TD syndrome is related to the malalignment of optic nerve and globe in the horizontal plane.
