Optical Coherence Tomography gives an unprecedented view of the macula and optic nerve. The contour maps and “virtual” cross section of the tissues gives invaluable information of eye health. This includes early detection of eye conditions such as macula degeneration and glaucoma. Stunning detail of the retinal structures, and a big step up from retinal photography.
Corneal ultrasound pachymetry allows easy measurement of corneal thickness. Using this technology we can make a more accurate assessment of glaucoma risk – thinner corneas are more of a concern. It gives a more accurate understanding of what the real eye pressures are and the need for treatment.
Computerised Visual Fields:
Peripheral vision testing is important in the screening for optic nerve abnormalities such as glaucoma. Subtle defects in side vision occur as the optic nerve fibres deteriorate. Most people are not consciously aware of these changes until the disease is well advanced.
Visual field assessment is another part of the puzzle for glaucoma diagnosis.
Mapping the shape and curvature of the cornea is useful in: measuring the amount of regular and irregular corneal astigmatism, advanced contact lens fitting, assessing suitability for laser surgery and diagnosing eye disease such as Keratoconus.
