Corneal epithelial debridement for the treatment of painful bullous keratopathy: A pilot study
Purpose: The aim of the study was to evaluate the outcomes of corneal manual epithelial debridement (MED) for the treatment of painful bullous keratopathy (BK). Methods: In a prospective interventional case series, 15 eyes of 15 consecutive patients presenting with painful BK of varying aetiology …

The effectiveness and safety of micropulse transscleral cyclodiode photocoagulation therapy in glaucoma patients at Groote Schuur Hospital, Cape Town, South Africa
… laser with its P3 probe was used. Baseline variables, including IOP, number of glaucoma medications and visual acuity (VA)were assessed. Success was set at a minimum of 20% reduction in baseline IOP, or a pressure drop to below 21mmHg at 6 months. Results Twenty-eight eyes of 15 female and …

Clinician measurement of spectacle prescription changes and patient tolerance to them
… prescription changes and improvements in visual acuity (VA) were often not reconciled and 93% reported not measuring VA to full threshold. The change in ocular astigmatism from with- to against-the-rule with age was more than three times more likely to pass through oblique axes than a …

Assessment of visual performance during walking
… ways, and because of age-related changes in various systems, including the visual system, acquiring accurate visual information of both stationary and moving objects may become challenging with age. New techniques for assessing dynamic visual performance with simultaneous evaluation of head …

Visual Performance in Pseudophakia. The Effect of Meridional Blur in Pseudoaccommodation.
The main aim of this thesis is to evaluate the effect of meridional blur, using refractive induced astigmatism, on visual performance at far and close distances. Visual performance was evaluated using letter discrimination tasks at distance and near (visual acuity, VA) and a reading task at near on …

Diabetic retinopathy among patients attending university teaching hospitals adult hospital medical clinic in Lusaka
Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus and also a leading cause of visual impairment among people in the working age group. Retinopathy develops overtime in all diabetics and controlling the modifiable risk factors delays its onset and progression. …

The Effect of SSRIs on Adult Human Visual Cortex Plasticity. Do SSRIs Affect learning?
… inhibitors (SSRIs) have been shown to enhance visual cortex plasticity in adult animals (Maya-Vetencourt, Sale et al. 2008). The aim of this study was to assess whether SSRIs increase visual cortex plasticity in humans. Methods: To test healthy visual plasticity, in the first experiment, …

Mild Traumatic Brain Injury with Associated Visual System Dysfunction: Investigating Histopathology, Functional Correlates, and a Novel Therapeutic Immune Modulator
… and often debilitating is its impact on the visual system. In order to further investigate the underlying pathology of mTBI and test potential therapeutics, we developed a mouse model of mTBI induced by blast overpressure. In this model, a 50-60 psi blast wave from a highly pressurized bolus …
