Diagnostic tests for Blindness:

Various tests are used in the diagnosis of Blindness. Some of these are listed below :

  • 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.
