Healthcare science staff working in this field assess the structure and function of the eye and the visual system. They study disorders of vision, plus diseases of the eye and the visual pathway. They carry out a diverse range of tests and procedures that may include:
- measurement of the field of vision
- measurement of the pressure in a patient’s eye
- taking images of the eye and its supporting structures
- taking measurements to determine the optical power of a lens to be inserted in the patient’s eye during cataract surgery
- electrophysiological investigation of the eye and visual pathways
By assessing and monitoring these various visual functions and structural changes, they provide essential diagnostic, prognostic and surveillance information to help ophthalmologists manage conditions such as glaucoma, cataract and diabetic retinopathy.
They may come into contact with patients with a range of problems, from poor sight through to complications of diabetes. They will see people of all ages, who will have a range of abilities and needs.
