PURPOSE To evaluate a haptic-based simulator, MicroVisTouch™, as an assessment tool for capsulorhexis performance in cataract surgery. The study is a prospective, unmasked, nonrandomized dual academic institution study conducted at the Wilmer Eye Institute at Johns Hopkins Medical Center (Baltimore, MD, USA) and King Khaled Eye Specialist Hospital (Riyadh,(More)
Choroidal osteomas are rare benign ossifying tumors that appear as irregular slightly elevated, yellow-white, juxtapapillary, choroidal mass with well-defined geographic borders, depigmentation of the overlying pigment epithelium; and with multiple small vascular networks on the tumor surface. Visual loss results from three mechanisms: Atrophy of the(More)
PURPOSE To report spectral-domain optical coherence tomography (SD-OCT) findings in polypoidal choroidal vasculopathy (PCV). PATIENTS AND METHODS Seventeen eyes of 15 consecutive patients diagnosed with PCV based on typical clinical and angiographic findings were imaged with macular SD-OCT including line scans passing through the polyps. RESULTS SD-OCT(More)
PurposePlacental growth factor (PlGF) is a member of the VEGF family that plays an important role in experimental models of diabetic retinopathy and retinal neovascularization. We aimed to investigate whether vitreous levels of PlGF correlated with proliferative diabetic retinopathy (PDR) status, VEGF levels, and bevacizumab treatment. We also analysed PDR(More)
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)(More)
CONTEXT Needle length plays an important role for the success of ophthalmic block. The standard practice is to use 25 mm needles length; however, unnecessarily long needles may increase the risk of complications especially in the presence of staphyloma or previous scleral buckle. AIMS This work was designed to compare the efficacy of using 15 and 25 mm(More)
BACKGROUND Kidney failure provoked by glomerulosclerosis leads to fluid filtration deficits and other disorders of kidney function. Refractory diabetic macular edema (DME) can be another warning sign of glomerulosclerosis in diabetic patients. CASE A 40-year-old Saudi male presented with macular edema that was refractory to all possible medical and(More)
In this report we describe, herewith, a patient with primary pigmentary dystrophy of the retina (retinitis pigmentosa) associated with unilateral retinal arteriovenous communication and exudative retinal detachment. The patient had complete resolution of the retinal detachment following laser photocoagulation treatment. Such association has not been(More)
Peribulbar block is commonly used for ocular posterior segment surgery. This work aimed to compare the efficacy of using 12.5 mm to 25 mm standard needle length in performing single injection peribulbar block for retinal surgery. Peribulbar block was performed in 120 patients using either standard 25 mm or 12.5 mm 30 G needle (insulin needle). While(More)
