Humphrey Visual Field Test

A Humphrey Visual Field Test is a special automated procedure that is used to perform perimetry, which is the systematic measurement of visual field function. The aim of the test is to measure the entirety of peripheral vision that can be seen while the eye is focused on a certain point.

Ocular Ultrasound

Ultrasound is used to assess the internal structure of the globe especially when vision is obstructed by a cataract or haemorrhage. The ultrasound can also be used in the assessment of intraocular masses and the measurement of tumor thickness for staging, as well as differentiating between choroidal or retinal detachments and some retro-ocular applications.

Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) is a non-invasive diagnostic technique that renders an in vivo cross sectional view of the retina. OCT utilizes a concept known as interferometry to create a cross-sectional map of the retina that is accurate to within at least 10-15 microns. Due to the transparency of the eye (i.e the retina can be viewed through the pupil), OCT has gained wide popularity as an ophthalmic diagnostic tool.

Orthoptic Consultation

Orthoptists are allied health professionals that specialise in the study of ocular motility and visual developments. Together with an ophthalmologist, the orthoptist examines and aids in the diagnosis of visual system dysfunctions involving vision, eye movement, eye alignment and binocularity. An orthoptic focuses on the non-surgical treatment of amblyopia and strabismus.
