    ABSTRACT: To ascertain the leading causes of endophthalmitis at the Tel Aviv Medical Center between 2003 and 2010. The design of the study is retrospective chart review. The medical records of all patients diagnosed with endophthalmitis in our center between 2003 and 2010 were reviewed for visual acuity and results of ophthalmologic examination at admission, treatment, complications, laboratory investigations, and final visual results. The etiologies of endophthalmitis after cataract surgery were compared for each year from 2003 to 2010, and after intravitreal (IVT) injection from 2006 to 2010. Eighty patients were diagnosed with endophthalmitis between 2003 and 2010: 46 male and 34 female, average age 70.7 years. A total of 27.5% were treated with IVT antibiotic injection only and 68.8% needed pars plana vitrectomy. Final visual acuity was better than counting fingers in 56.3% of cases. Surgery was almost the sole cause of endophthalmitis until 2005, when IVT injection became an important etiology. The incidence of postcataract endophthalmitis decreased significantly after 2007 and that following IVT injection decreased significantly after 2008. The leading etiology of endophthalmitis changed from postoperative endophthalmitis to endophthalmitis after IVT injection from 2003 to 2010, and the incidence of the infection as a complication of those procedures decreased.

    ABSTRACT: We sought to assess long-term changes in the flow parameters of retrobulbar vessels in diabetic patients. The retrobulbar circulation of 138 eyes was evaluated between 1994 and 1995 and 36 eyes were reevaluated between 2004 and 2008 (study group). They were divided into four groups: eyes of diabetic patients without diabetic retinopathy (DR), eyes with nonproliferative DR, eyes with proliferative DR, and eyes of nondiabetic patients (controls). Color Doppler imaging was used to assess the flow velocities in the major retrobulbar vessels. The resistive index (RI) was calculated and compared among the groups and between the two time periods. RI values of the central retinal artery and posterior ciliary artery had increased in the two non-DR groups and in the nonproliferative DR group, with a surprising decrease measured in eyes with proliferative DR (P= nonsignificant [NS]). Combining the nonproliferative DR and proliferative DR groups resulted in a milder increase of the RI of the posterior ciliary artery (P= NS) and the central retinal artery (P=0.02) in the DR group compared to the other groups. Our results demonstrate that an increase of the resistance in the retrobulbar vessels, as a part of DR, can lessen over time and may even be reversed.

    ABSTRACT: To describe the spectral-domain optical coherence tomography (SD-OCT) findings in a case of Coats' disease, with emphasis on the intraretinal exudates. Case report of a 4.5-year-old girl who presented with total exudative retinal detachment and organized exudates in a stellate configuration. SD-OCT was performed before and after treatment, which included surgical drainage of subretinal fluid and indirect laser application during the surgery. At presentation, the SD-OCT showed an elevation of the foveal contour, with thickening of the retina, many exudates and a large quantity of subretinal fluid. Two months after the surgical treatment, SD-OCT revealed a significant reduction in the amount of subretinal fluids, but with persistence of the exudates. SD-OCT can be used as an important tool in order to describe the changes in each layer of the retina in Coats' disease. Considering the histopathological findings in Coats' disease, it is reasonable to assume that the exudates accumulate in the outer plexiform layer.
