Diagnostic Tests for Blindness
Diagnostic Test list for Blindness:
The list of diagnostic tests
mentioned in various sources as
used in the diagnosis of Blindness
- Physical examination
- Blood pressure - high blood pressure increases risk of hypertensive retinopathy, stroke and central retinal vein thrombosis.
- Visual acuity - reflects the integrity of the central field.
- Visual field testing - to detect either a contraction (a local or general reduction in the area of field) or a scotoma (an island of loss within the field). Use Confrontation testing, Perimetry testing and Central field testing. Mapping the visual field defect can help determine cause.
- Examination of pupils
- Ophthalmoscopy and slit lamp examination - to examine the optic nerve, macula and retina and assist in diagnosis of corneal opacities, cataracts, choroiditis, glaucoma, retinitis, retinal hemorrhage, detached retina. Specifically look for papilledema (swelling of the optic nerve) which suggests optic neuritis, retinal vein thrombosis and brain tumors.
- Ocular motility testing
- Measure intraocular pressure (tonometry) - to detect glaucoma.
- Full neurological examination - if abnormalities other than eye pathology are found on examination may suggest multiple sclerosis, carotid artery thrombosis or insufficiency, basilar artery thrombosis or insufficiency, pseudotumor cerebri; if neurological examination is normal may suggest occipital lobe tumor, posterior cerebral artery thrombosis, hereditary optic atrophy, early pituitary tumor, tobacco or alcohol poisoning.
- CT Brain and/or MRI Brain (if neurological abnormalities are present) to detect stroke, optic nerve lesion, brain tumors
- Carotid artery ultrasound - to detect atherosclerosis of the carotid arteries.
- Visually evoked potential (VEP) studies and/or spinal fluid analysis (if neurological abnormalities are present) to detect demyelinating disorders e.g. multiple sclerosis
- Temporal artery biopsy - if suspect temporal arteritis.
- Blood tests
- If suspect pituitary tumor test prolactin, testosterone (in males), LH, FSH, TSH, thyroxine, cortisol ESR elevated in temporal arteritis
- Blood sugar to diagnose diabetes
