Purpose To demonstrate the clinical pathologic correlation in a hemorrhagic choroidal melanoma. Observations A 52 year old patient presented with a large choroidal mass associated with vitreous and retinal hemorrhage. The eye was enucleated and histopathology demonstrated epithelioid-type MART1 positive tumor cells consistent with choroidal melanoma. The tumor had broken through Bruch's membr...

BACKGROUND Intraschisis hemorrhage of dark green color without accompanying vitreous hemorrhage is a rare complication of degenerative retinoschisis-detachment. CASE A 37-year-old male patient with unilateral intraschisis hemorrhage closely mimicking a choroidal melanoma is described. OBSERVATIONS Ultrasonography and intravenous fluorescein angiography suggested intraschisis hemorrhage. T(1...

Purpose. To describe our technique, clear corneal phacovitrectomy with posterior capsulorhexis (CCPV), for the management of selected posterior segment intraocular foreign body (IOFB), posteriorly dislocated lens fragments (PDLF), and proliferative diabetic retinopathy (PDR) cases. Methods. This was a single-center retrospective interventional case series. In 21 patients (21 eyes) we performed ...

Purpose. To identify and study causes of vitreous hemorrhage (VH) in pediatric age group and to investigate factors predicting visual and anatomical outcomes. Procedure. A retrospective review of patients aged 16 years or less with the diagnosis of vitreous hemorrhage from January 2005 until December 2010. Results. A total number of 230 patients (240 eyes) were identified. Traumatic vitreous he...

PURPOSE To examine the levels of Müller cell contraction-stimulating activity in human vitreous, correlate these levels with clinical presentation, and identify, the causative growth factors. METHODS Human vitreous was collected from patients undergoing pars plana vitrectomy (n = 84). Müller cells were isolated from porcine retina and maintained in tissue culture. Tractional forces generated ...

BACKGROUND Angiogenesis plays an important role in the mechanism of diabetic retinopathy (DR). Visfatin, a recently identified adipokine, is thought to possess an angiogenic effect. The aim of our study was to investigate serum and vitreous levels of visfatin in patients with proliferative diabetic retinopathy (PDR) and non-PDR (NPDR). MATERIAL AND METHODS A total of 280 diabetic patients (12...
