Visual Field Test 

Visual field test is used to measure the field (scope) and sensitivity of vision, playing a vital role in diagnosing glaucoma, retinitis pigmentosa and other diseases that influence visual field (e.g. brain tumours). A good visual field is particularly vital to drivers as it helps to ensure driving safety.


Eye diseases (e.g. glaucoma, cataract, retinal detachment and macular degeneration) that influence the visual field may not have obvious symptoms at their early stage. This might lead to a delay in detection and treatment of the diseases and result in permanent visual damage.

Our centre is equipped with a world-class Computerised Visual Field Analyzer, which can effectively measure visual sensitivity as well as visual field.

During the test, you are required to cover one of your eyes, with the uncovered one focusing on detecting flashes of light. The computer programme will project different brightness and sizes of light spots in varies locations inside the equipment, while you need to press buttons based on the flashes you see. After testing both eyes, the system will analyse the collected data, comparing it with the norm data and analyse your eye condition.
