This module provides an introduction to the aetiologies, signs, symptoms and investigation of common ophthalmic disorders encountered during orthoptic clinical practise through a range of lectures and tutorials. Students will be introduced to the technologies that allow the diagnosis of these conditions, and the impact of genetics and biological processes on the eye. This is the first in a series of three modules (including ORTH 235 and ORTH 334) related to the wider topic of ophthalmology which students will encounter in orthoptic practice. The module assessment is comprised of two online examinations, one mid module (45 minutes duration), and one at the end of the module (90 minutes duration).
