The Role of the crystalline lens in ametropia
When examining the dimensions of the crystalline lens, it is found that some may vary with different types of refractive error. The effects of several of these variations on refractive error are investigated in this thesis. To examine whether lens thickness was significantly different in …

An investigation of the relationship between the structure and function of the myopic eye. Correlating the optical, functional and structural aspects of ametropia in young adult humans.
The increasing prevalence of myopia over the past few decades and its association with potential ocular complications make myopia an important research topic. The present work is concerned with the structural and functional characteristics of a group of myopic and emmetropic individuals. The …

Myopia: structural and functional correlates
… of young adult subjects (n=76) with a range of ametropia (MSE= -19.76 to +4.38D). Specific MRI derived parameters of ocular shape are then correlated with measures of visual function. Key findings include the significant homogeneity of ocular volume in the anterior eye for a range of refractive …

Duane's retraction syndrome in a cohort of South African children a 20 year clinic based review
… Up and downshoots were seen in 58 (48.3%). Ametropia was found in 94 (79%), and of these 88 (93,6%) were hyperopic and 6 (6.4%) myopic. Amblyopia was present in 15 (12.5%). Surgery was performed in 41(34%). CONCLUSION: This study is the first to provide robust data on the profile of …

Visual Function in New Zealand Children: from Preschool to Primary School
… children. Up to 84% of New Zealand children with ametropia did not have appropriate correction. While the current vision screening programme was effective for detecting children with amblyopia risk factors, the addition of autorefraction significantly improved its sensitivity for detecting …

Vergleich der Mikrokeratome Amadeus II und Hansatom hinsichtlich Komplikationen und funktionellem Ergebnis nach LASIK : eine retrospektive Studie
INTRODUCTION: Today LASIK is the most common method in refractive surgery. In classical LASIK preparation of the flap is done mechanically by a microkeratome, of which meanwhile there are many different types. The aim of this study is a comparison of the two common Microkeratomes Amadeus II from …
