OBJECTIVE To investigate the adverse ocular effects of intravitreal ketorolac (4 mg) in patients with chronic uveitis and complications of chronic inflammation (macular edema). METHODS We conducted a prospective phase 1 clinical trial involving 10 eyes of 10 adult patients with chronic inflammation and/or macular edema for whom previous treatment failed or who could not tolerate corticosteroi...

purpose: to report visual outcomes of pars plana vitrectomy in severely traumatized eyes with no light perception (nlp) and flat electroretinography (erg) methods: we performed a prospective interventional study on 22 severely traumatized eyes with nlp, 4+ relative afferent pupillary defect (rapd) and flat erg. results: one year after pars plana virectomy, 15 patients (68.18%) had nlp, six pati...

The electroretinogram (ERG) response evoked in man by intense illumination pre­ sents a series of oscillatory potentials super­ imposed on the b-wave." These oscillatory potentials are of clinical importance, since in the presence of certain diseases they are reduced or disappear prior to some changes of the aand b-waves. Measurement of the amplitude of the os­ cillatory potential is difficult,...

DEDICATION I dedicate my thesis work to my loving family and friends. A special feeling of gratitude to my amazing parents, Mohammad and Abeer, whose words of encouragement and push for tenacity ring in my ears. My brothers and sisters are also to thank due to their love and support. I also dedicate this thesis to my friends who have supported me throughout the process which made it easier for ...

The contrast transfer function (CTF) of the pattern electroretinogram (PERG) depends on temporal frequency. For transient stimulation it is fully linear; at faster stimulation rates it becomes strongly non-linear with an accelerated shape. In this study we investigated a range of stimulus parameters with the aim of studying the influence of temporal and spatial frequencies, as well as contrast ...
