Abstract
The elderly are disproportionately affected by glaucoma, a kind of irreversible visual neuropathy caused by persistently high intraocular pressure.
Diagnosing and treating glaucoma at any stage requires examination related to the eyes’ visual field testing.
When the central 5 degrees are impaired and/or the mean deviation is more than 12 dB, a visual field test indicates an advanced stage of glaucoma.
Some patients with advanced visual detorioration may have difficulty distinguishing white perimetric stimulus size III. To increase the dynamic range into the low vision zone and to make the stimulus more obvious, size V Goldmann stimuli are sometimes utilised instead of the more common size III. The 16-fold increase in its surface area surely aids in its visibility.
This thesis set out to compare the accuracy of conventional perimetry in detecting visual field anomalies in people with advanced glaucoma to that of a low vision programme..
Thirty participants with advanced glaucoma had their ocular data analysed in our research. All aspects of patients’ eyesight, including their peripheral and central vision, as well as their ability to perceive colour and their intraocular pressure, were evaluated (IOP). We took a little pause in between checking both conventional and low-vision systems on each eye. Fifteen eyes were examined by octopus perimeter and fifteen eyes were examined by Humphrey field analyzer.
