![]() Other instruments are now available for detecting and monitoring glaucoma but these are the most commonly used tests. Tonometry - measuring the pressure within the eye, either using an instrument that emits a small puff of air onto the surface of the eye, or placing a probe against the eye after it has been numbed with anaesthetic drops. Visual field assessment - testing the field of vision using small points of light to check for blind spots. Ophthalmoscopy - checking the appearance of the optic disc (where the optic nerve joins the eye) using an ophthalmoscope, a special torch for looking into the eyes. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema. There are three main tests that may be carried out by an optometrist to check for glaucoma: Most new cases of glaucoma are identified through referrals from optometrists, whose training equips them to recognise the early signs of the disease.

In most cases glaucoma sufferers will experience no symptoms until significant damage has occurred. Regular glaucoma check-ups include two routine eye tests: tonometry and ophthalmoscopy. CRAO is the ocular analogue of a cerebral strokeand, as such, the clinical approach and management are. Patients typically present with profound, acute, painless monocular visual losswith 80 of affected indiĀviduals having a final visual acuity of counting fingers or worse. to determine the rate and predictors of abnormal ocular fundus findings. Central retinal artery occlusion (CRAO) is an ocular emergency. Perimetry (visual field test) The angle in the eye where the iris meets the cornea. pupillary dilation is essential to an accurate funduscopic examination and may. ![]() This leads to a reduction in the field of vision and in the ability to see clearly. Ophthalmoscopy (dilated eye exam) The complete field of vision. Glaucoma is the name for a group of eye conditions in which the optic nerve (the nerve at the back of the eye) is damaged, often in association with raised pressure within the eye. ![]()
