Study Develops Normative Data for Visual Function Parameters

Study Develops Normative Data for Visual Function Parameters
PhD in Optometry graduate, Dr Charles Darko-Takyi.

Dr Charles Darko-Takyi was awarded a PhD in Optometry for his study that developed normative data for visual function parameters for a West African school going population using simple, inexpensive but acceptable free-space optometric clinic techniques.

The study investigated expected binocular visual function data among normal junior high school children in the central region of Ghana and compared these results with data from other populations. It was supervised by UKZN’s Professor Vanessa Raquel Moodley and co-supervised by Dr Samuel Bert Boadi-Kusi of the University of Cape Coast.

A total of 1 261 normal participants between the ages of 11 and 17 were selected for comprehensive binocular vision testing. ‘My data now serves as the expected data for the West African population and guides eye doctors, especially optometrists to accurately diagnose and manage binocular vision problems among West African children,’ said Darko-Takyi.

Three publications have resulted from his work, one of which has been published in African Vision and Eye Health, with the other two having been peer-reviewed.

Darko-Takyi is a Research Fellow (lecturer) in the College of Health Sciences, University of Cape Coast, Ghana. He is also a practicing optometrist at the UCC eye and optometric clinic.

‘I would like to be involved in campaigns to promote optometric practice in Africa and the world. My interest is promoting the practice of binocular vision in eye clinics on the continent,’ he said.
