Impaired vision

Impaired vision: Introduction

Any type of vision loss (e.g. blindness, blurred vision, double vision, etc.) is a symptom of great concern. Many of the causes are very serious medical conditions.

Diagnostic tests for Impaired vision:

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

  • Physical examination
    • Blood pressure - high blood pressure increases risk of carotid artery insufficiency, hypertensive retinopathy, papilledema and stroke.
    • Visual acuity - in both eyes and with and without glasses (if worn) to determine any refractive error.
    • 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. e.g. glaucoma, pituitary tumor, toxic causes such as methyl alcohol.
    • Examination of pupils and the pupil reflexes
    • Ophthalmoscopy and slit lamp examination - to examine the optic nerve, macula and retina and assist in diagnosis of cataracts, iritis, keratitis, glaucoma, retinitis, foreign bodies, detached retina. Specifically look for papilledema (swelling of the optic nerve) which suggests optic neuritis.
