Applanation Tonometer
Tonometry is the procedure eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma.Most tonometers are calibrated to measure pressure in millimeters of mercury.
Ophthalmic Ultrasound – A
Ophthalmic ultrasonography uses high-frequency sound waves, which are transmitted from a probe into the eye. ... For sound to be considered ultrasound, it must have a frequency of greater than 20,000 oscillations per second, or 20 KHz, rendering it inaudible to human ears.
Fundus Photography
Fundus photography involves capturing a photograph of the back of the eye i.e. fundus. Specialized fundus cameras that consist of an intricate microscope attached to a flash enabled camera are used in fundus photography.
Perimetry (Visual Field Testing)
A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits. Visual field testing can be performed clinically by keeping the subject's gaze fixed while presenting objects at various places within their visual field.
Non Contact Tonometer
A tonometer is a diagnostic tool used by eye care professionals to measure the intraocular pressure (IOP) inside a patient's eyes. A patient's IOP can help an ophthalmologist or optometrist determine a patient's risk for developing glaucoma — a disease that damages the optic nerve of the eye, usually resulting in vision loss or even blindness.
