PURPOSE To study the correlation among cataract grading system by Scheimpflug imaging (Oculus Pentacam® Nucleus Grading System [PNS]), effective phaco time (EPT), and surgical time (ST) using peristaltic and venturi pumps on the Whitestar Signature Phaco System (Abbott Medical Optics, Inc., Santa Ana, California, USA). 
 METHODS Patients scheduled to have(More)
Although retrograde transsynaptic degeneration in the visual pathway of monkeys has been described since 1963, data in humans are sparse. The authors present a 24-year-old female referred to a neuro-ophthalmology consult for assessment before neurosurgery for a right occipital ependymoma. Clinical examination was unremarkable, including visual fields(More)
Photosynthetic capacity (PC) of three peanut cultivars (Arachis hypogaea L. cvs. 57-422, 73-30, and GC 8-35) decreased during drought stress (decline in relative water content from ca. 95 to 70 %) and recovered two days after rewatering. Mild water stress was not limiting for the total ribulose-1,5-bisphosphate carboxylase/oxygenase activity, since this(More)
Most panuveitis in children are caused by infectious agents. A detailed clinical history and clinical examination are helpful in the diagnosis, but specific techniques are sometimes required to identify the causing specimen. We report the first published case of panuveitis in a child caused by simultaneous ocular infection by Toxocara canis and a fly larva(More)
1 of 1 DESCRIPTION Opsoclonus-Myoclonus syndrome is a rare dyskinesia due to an underlying infectious, metabolic or neoplastic process. 1 It is frequently caused by neuroblastoma in children and breast or lung carcinoma in adults. It is characterised by high amplitude, multidirectional, arrhythmic and conjugate ocular saccadic intrusions without(More)
Intraocular tuberculosis (TB) infection can have different clinical manifestations including retinal vasculitis. It more frequently involves the veins and is associated with retina haemorrhages and neovascularisation. The diagnosis may be difficult and presumptive being based on clinical findings and evidence of systemic TB infection. The authors present a(More)
Choroidal tuberculosis (TB) infection may present itself as a diffuse choroiditis that resembles serpiginous choroiditis, usually treated with immunossupressants. Recent studies have demonstrated that patients with serpiginous-like choroiditis and evidence of systemic or latent TB are best treated with antituberculosis treatment (ATT) in addition to the(More)
Introduction Tolosa-Hunt syndrome (THS) is one of the most common 'benign' causes of painful ophthalmoplegia. Diagnosis is based on clinical and imaging findings and the exclusion of other causes because there is no specific biomarker for the syndrome. Eales disease, an idiopathic inflammatory venous disease that primarily affects the eye, can also affect(More)
The effect of different concentrations of lead was investigated in two different ways in the leaves of Helianthus annuus plants. In the first way, removed leaf discs from 5-wceks old plants were floated in 0.05, 0.25, 2.50 and 5.00 mM PbNO3 solutions for 2, 4 and 6 days. In addition, the chlorophyll content and the activity of peroxidase enzyme which are(More)
Th17 cells, a CD4+ T-cell subset, produce interleukin (IL)-17, a pro-inflammatory cytokine that has been shown to be involved in several forms of infectious and noninfectious uveitis. Here, we explore the roles of this IL in uveitic disorders as well as in experimental autoimmune uveitis, the possible pathogenic implications of several cytokines associated(More)
