Diagnostic tests for Pupil symptoms:

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

  • Eye examination
    • Inspect the eye noting the nature of redness, if present. This will help delineate iritis and glaucoma which may cause pupil dilation
    • Examine the pupils for size, shape, equality and regularity
    • Test the light and accommodation reflexes of the pupils. Usually a light shone into the pupils will cause the pupil to constrict. Usually focusing from a far object to a near object will cause the pupil to constrict
    • Unilateral pupil dilation which is not reactive to light or accommodation (focusing on near object) would suggest oculomotor nerve (third cranial nerve) palsy due to a ruptured brain aneurysm or intracranial haematoma (brain blood clot). If a unilateral dilated pupil reacts to both light and accommodation, must consider a local eye condition such as iritis, glaucoma, anisocoria (a condition in which the two pupils are not of equal size) or irritation of the cervical sympathetic nerves. If a unilateral dilated pupil reacts to accommodation but not to light, must consider neurosyphilis. If a unilateral dilated pupil does not react to light or accommodation, must consider blindness due to optic nerve (second cranial nerve) lesions
    • Examine for signs of Horner's syndrome such as partial ptosis (dropping down of the eyelid), unilateral constricted pupil which does react normally to light, and a decrease of sweating over the involved eyebrow
