  1. How long have you noticed the cloudy vision vision?

    Why: to determine if acute or chronic.

  2. Is it unilateral or bilateral?

    Why: if unilateral would suggest local eye causes such as cataract, refractive error, iritis, glaucoma, keratitis, retinal detachment, foreign body, vitreous hemorrhage, optic neuritis, orbital fracture. If bilateral may suggest cocaine use, methyl alcohol poisoning, tobacco, barbiturates, quinine and other drugs. Bilateral cloudy vision can also with cataracts, glaucoma, chorioretinitis, retinitis pigmentosa, optic atrophy, papilledema, papillitis, optic neuritis, refractive error, pituitary tumors, posterior cerebral artery occlusion, concussion, migraine and hysteria.

  3. Is it transient or constant?

    Why: if transient may suggest migraine, carotid artery insufficiency or diabetic swelling of the lens.

  4. Was it sudden in onset?

    Why: may suggest migraine, optic neuritis, vitreous hemorrhage, iritis, keratitis, glaucoma, retinal detachment, foreign body, retrobulbar neuritis, orbital fracture, carotid artery insufficiency and hysteria.

  5. Drug or alcohol ingestion?

    Why: e.g. cocaine, tobacco, barbiturates, methyl alcohol, quinine and other drugs may be responsible.

  6. Past medical history?

    Why: e.g. diabetes increases risk of cataracts, glaucoma and retinal detachment; multiple sclerosis and syphilis can cause optic neuritis; migraine can cause transient blurriness of vision; Down syndrome, Marfan's syndrome, sarcoidosis and classic galactosemia can be complicated by cataracts.

  7. Past refractive error?

    Why: e.g. myopia (short-sightedness) people are at increase risk of retinal detachment and macula degeneration.
