Öğe Color doppler imaging of ocular hemodynamic changes in Behcet's disease(Elsevier Science Inc, 2004) Çaça, I; Nazaroglu, H; Ünlü, K; Cakmak, SS; Ari, S; Sakalar, YBPurpose: A prospective evaluation of the Ocular blood flow velocity in patients with Behcet's disease was carried out to determine its changes. Methods: Subjects were divided into three groups: those with ocular involvement in Behcet's disease (goup I), those without ocular involvement in Behcet's disease (goup II), and a control group (group III). Twenty-seven eyes in group I and 28 eyes each in groups II and III 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 mean blood flow velocity of the central retinal vein (CRV) was also measured. These results were then compared among the three groups of subjects. Results: The PSV values of CRA in groups I and II were found to he significantly lower than those in the control group (P < 0.001, P = 0.018, respectively). The PSV values of CRA in group I were found to be significantly lower than those in group II (P < 0.001). The EDV values of CRA in groups I and II were found to be significantly lower than those in the control group (P < 0.001, P = 0.034, respectively). The EDV values of CRA in group I were significantly lower than those in group II (P = 0.041).The PSV values of OA in group I were significantly lower than those in the control group (P = 0.002). The EDV values of OA in group I were significantly lower than those values in group II or the control group (P = 0.001 and P = 0.037. respectively).The PSV values of NPCA in group I were significantly lower than those ill the control group (P = 0.007). The PSV Values of TPCA in groups I and II were significantly lower than those ill the control group (P < 0.001. P < 0.001. respectively). The EDV values of TPCA in group I were significantly lower than those values in group II or the control group (P = 0.014 and P = 0.003, respectively). There were no significant differences in the mean blood flow values of the CRV among all three groups (P > 0.05). Conclusions: There are significant reductions in the blood flow values of the orbital arteries in patients with Behcet's disease, and they are more evident in those with ocular involvement. This might be the result of occlusive vasculitis, which is frequently seen in the retinal vessels of patients with Behcet's disease.

A few cases of IFK have been reported in the literature, but it appears that IFK on the conjunctiva has never been reported. Case: A 21-year-old man was referred for evaluation of a conjunctival mass. Observations: By slit-lamp biomicroscopy, an 8 X 5 X 3 mm mass was observed over the nasal conjunctiva adjacent to the limbus in the left eye. An excisional biopsy of the lesion was carried out. The results of a pathologic examination showed IFK. During the 9-month follow-up period, the patient had no recurrence of the lesion. Conclusion: IFK can be considered in the differential diagnosis of conjunctival masses as a rare specific lesion.

We report our successful treatment of three patients with cutaneous lesions in the periorbital area. Cases: In this study, we report on the treatment of three female patients who were initially diagnosed as having preseptal cellulitis. Observations: Gram-positive robs were revealed in the microscopic examination of scrapings taken from the lesions. Bacillus anthracis was found in only two of the three scraping-material cultures. Intravenous penicillin G was administered in all cases. Black and necrotic eschar, which is characteristic of anthrax, developed on the eyelids of all three patients during treatment. At the final examinations of the patients after the completion of treatment, we recognized the development of cicatrisation, lagophthalmos, and slight ectropion in the upper eyelid of the first patient, and, in the second patient, restriction of upper eyelid movement and development of a corneal scar from exposure keratopathy and ectropion. The cutaneous lesions healed without any eyelid pathology in the third patient. Conclusion: Although it is a rare disease in humans, anthrax should be considered in the differential diagnosis of preseptal and orbital cellulitis.

This study analysed 420 patients with penetrating eye injuries who presented for treatment at the Eye Clinic of Dicle University Hospital in Turkey. The aim of the study was to identify preventable risk factors. Methods. A retrospective evaluation of patients who presented between January 1995 and December 2000 was undertaken. Cases were examined with regard to age, sex, profession, which eye was traumatized, reason for the trauma, nature of the trauma, time between injury and operation, and accompanying pathologies. Results. This study found that most penetrating eye injuries occurred in children aged 0-15 years, and these were mainly caused by accidents during play. For patients aged 16-60 years, penetrating eye injuries were mainly caused by work-related accidents. Conclusion. Most penetrating eye injuries were caused by preventable accidents. Many accidents and their resulting injuries could have been prevented by education, greater intensive care and workplace safety. (C) 2004 The Royal Institute of Public Health.

Material/Methods: We retrospectively evaluated 132 eyes in 76 patients with congenital cataracts who underwent cataract surgery between January 1995 and December 2000. The patient age at surgery, surgical technique, post-operative complications, and final visual prognosis were evaluated. Results: Thirty eyes underwent aspiration, posterior capsulotomy, and intraocular lens (IOL) implantation; 22 eyes underwent aspiration and posterior capsulotomy; 39 eyes underwent aspiration, posterior capsulotomy, and anterior vitrectomy; and 41 eyes underwent aspiration, posterior capsulotomy, anterior vitrectomy, and IOL implantation. The most frequent complications were secondary cataract (24.2%), posterior synechiae (9.1%), and glaucoma (3%). Groups were compared according to surgical technique and incidence of complications. Complications occurred most frequently with aspiration and posterior capsulotomy and occurred less frequently with aspiration, posterior capsulotomy, and anterior vitrectomy; these differences were statistically significant (p < 0.05). The difference in the final visual prognosis was statistically significant in the aspiration, posterior capsulotomy, anterior vitrectomy, and IOL implantation groups as compared with the other groups (p < 0.05). The mean follow up times was 15.5 +/- 1.78 months. Conclusions: The most frequent complication of congenital cataract surgery is secondary cataract formation. Today, posterior capsulotomy with anterior vitrectomy is the preferred method for decreasing the incidence of this complication.Öğe Therapeutic effect of culture and antibiogram in bacterial corneal ulcers(Amer Soc Contemporary Ophthalmology, 2005) Çaça, I; Ünlü, K; Ari, S; Sakalar, YBCorneal scraping material was taken from 58 eyes of 58 patients with bacterial corneal ulcer. Ulcer size and epithelial healing were determined using biomicroscopy. A combination of cefazolin 33 mg/mL and gentamycin 14 mg/mL was administered before cultures results were returned. Mean ulcer size and epithelial healing in culture negative patients were significantly lower than in culture positive patients.
