The identification and measurement of autistic features in children with optic nerve hypoplasia, "isolated" hypopituitarism and varying combinations of septo-optic Dysplasia
… of intellectual disability, and also their visual loss, but not their hormone deficiencies. The theses found that those children with greater severities of neurological impairments were more vulnerable children to autistic disorders. Furthermore, sensory impairments, and Self Injurious …

Improving the detection of correctable low vision in older people
… is often assumed that older people with vision loss will have regular eye examinations so that these problems can be detected, but for many older people this assumption is wrong. One approach to improving the take-up of eyecare services is to carry out vision screening of older people in the …

Development of Techniques for Analysis of the Human Retinal Ganglion Cell Transcriptome: Application to the Role of Calcium in RGC Death in Glaucoma
… ganglion cell (RGC) death is the reason for visual loss in glaucoma. However, the mechanisms of RGC death remain unclear. The aim of this research was to develop methods to study mRNA expression profiles in human RGCs, then to use the data to investigate the role of calcium in RGC death. …

Eye movements, search and perception of visual field defects in glaucoma
… the optic nerve that can result in irreversible loss of visual function and impairment in everyday visual tasks. The experimental studies described in this thesis primarily aim to investigate the performance of people with glaucoma on search and other visual tasks whilst simultaneously monitoring …

Expert patient programme for recently diagnosed patients with chronic open angle glaucoma (COAG)
… to the optic nerve, resulting in peripheral visual loss that can progress to involve the fovea and central vision; subsequently causing blindness. COAG is reported to have a poor level of adherence to treatment due to its asymptomatic nature. In this study, a Glaucoma Expert Patient Programme …

Modelling and correction of retinal pathologies caused by mitochondrial DNA mutations via genetic engineering
… lack curative treatments and lead to progressive visual loss. Although advances in genetic engineering have enabled the modelling and correction of nuclear DNA mutations in the retina, challenges remain in modifying mtDNA. The generation of accurate models that mimic retinal mtDNA diseases and …

Structural Integrity of Eyes Diagnosed with Amblyopia. The measurement of retinal structure in amblyopia using Optical Coherence Tomography.
Amblyopia is the leading cause of monocular visual impairment in children. Therapy for amblyopia is extremely beneficial in some children but ineffective in others. It is critical that the reasons for this discrepancy are understood. Emerging evidence indicates that current clinical protocols for …

On Complications to Cataract Surgery
… (62%) of eyes experiencing RD had a poor visual outcome of 0.1 or less. In patients with late IOL dislocation the median time to repositioning surgery was 6.5 years. This interval was significantly shorter in older patients and in eyes with perioperative complications (3.2 years). …

Variations in arterial supply via the external and internal carotid arteries to the bony orbit and eyeball in full-term fetuses, infants, children, adolescents, and adults – a South African perspective
… which may lead to partial or complete visual loss. Up until the present time, there have been only a few cadaveric studies that revealed some of the variant patterns and the overall frequencies of the recorded anastomotic patterns for the orbital blood supply. Whilst the anatomical …

Diabetic macular oedema: the role of steroids and VEGF
… benefits since it reduces the chance of moderate visual loss by approximately 50% and is unlikely to improve visual acuity. Intravitreal steroids have been used in the treatment for diabetic macular oedema. Initial pilot studies suggest it can decrease retinal thickening and increase visual acuity …
