A 74-year-old man underwent uneventful phacoemulsification and posterior chamber intraocular lens implantation in left eye under peribulber anaesthesia. On the first postoperative day, the patient complained of vision loss in the in the left eye with a visual acuity of 1-m finger counting. After complete ocular, fluorescein angiographic, electrophysiological, systemic and laboratory evaluation, the diagnosis of posterior ischaemic optic neuropathy was made. This case highlights that posterior ischaemic optic neuropathy is a rare clinical entity and should be diagnosed only after exclusion of all other causes in differential diagnosis of postoperative visual loss.

Çalışmamızda 2011 yılı içinde kliniğimize başvuran, paintball travması ile olan göz yaralanması saptanan beş olgu retrospektif olarak incelenmiştir. İki olguda glokom, dört olguda retinal ödem, üç olguda retinal hemoraji, üç olguda koroid rüptürü, bir olgu da cerrahi gerektiren travmatik katarakt izlenmiştir. Bir olguda travma olan gözde legal körlük düzeyinde kalıcı görme kaybı gelişmiştir. Çalışmamızla Türkiye'de de hızla yayılan bu saha savaşı oyununun ciddi göz patolojilerine yol açabileceğine dikkat çekilmek istenmiş, oyuna katılanlar, ticari kuruluşlar ve denetleyici kurumlara yönelik yapılması gerekenler özetlenmiştir

Subjects were divided into four groups: those with ocular involvement in Behçet disease (group I), those without ocular involvement in Behçet disease (group II), uveitis patients with different etiologies (group III), and a control group (group IV). Twenty-seven eyes in group I, 14 eyes in group II, 25 eyes in group III, and 27 eyes in group IV were investigated. The blood flow in the central retinal artery (CRA), ophthalmic artery (OA), nasal posterior ciliary artery (NPCA), and the temporal posterior ciliary artery (TPCA) was measured using color Doppler ultrasonography (CDU) to determine the peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI). The PSV and EDV value of CRA in groups I, II, and III were found to be significantly lower than those in the control group (p < 0.05 for each). The PSV and EDV values of TPCA and NPCA in groups I, II, and III were significantly lower than those in the control group (p < 0.05 for each). Resistivity indexes of all arteries were higher in groups I, II, and III than the control group. The PSV and EDV in CRA, TPCA, and NPCA in Behçet disease patients with ocular involvement were significantly lower than all other groups (p < 0.05). There are significant reductions in the blood flow values of the orbital arteries in patients with Behçet disease and uveitis patients with different etiologies when compared with healthy volunteers. The decrease in blood flow values in Behçet disease is more evident in patients with ocular involvement than the patients without ocular involvement. This might be the result of occlusive vasculitis, which is frequently seen in the retinal vessels of patients with Behçet disease.
