StemCell Therapy

Sudden loss of vision without eye pain

Blindness in one eye lasting minutes to hours

Ultrasonography of the carotid arteries

Echocardiogram (ultrasound of the heart)

Continuous monitoring of heart rhythm

Almost instantaneous, complete loss of vision in one eye

In people with risk factors for atherosclerosis (such as high blood pressure, abnormal blood lipids, or cigarette smoking)

Measurement of ESR (a blood test), C-reactive protein, and platelets

In people with risk factors for this disorder (such as diabetes, high blood pressure, a tendency for blood to clot excessively, or sickle cell disease)

Vitreous hemorrhage (bleeding into the vitreous humorthe jellylike substance that fills the back of the eyeball)

In people who have had specks, strings, or cobwebs in their field of vision (floaters) or who have risk factors for vitreous hemorrhage (such as diabetes, a tear in the retina, sickle cell disease, or an eye injury)

Usually loss of the entire field of vision (not in just one or more spots)

Examination by an ophthalmologist

Sometimes ultrasonography of the retina

Sometimes headache, pain while combing the hair, or pain in the jaw or tongue when chewing

Sometimes aches and stiffness in the large muscles of the arms or legs (polymyalgia rheumatica)

Measurement of ESR, C-reactive protein, and platelets

Biopsy of the temporal artery

In people with risk factors for this disorder (such as diabetes or high blood pressure) or in people who have had an episode of very low blood pressure, which sometimes causes fainting

Measurement of ESR, C-reactive protein, and platelets

Sometimes biopsy of temporal artery

Sometimes carotid artery Doppler (ultrasound of the neck veins) and echocardiogram (ultrasound of the heart)

Macular hemorrhage (bleeding around the maculathe most sensitive part of the retina) resulting from age-related macular degeneration

Usually in people known to have age-related macular degeneration or in people with risk factors for blood vessel disorders (such as high blood pressure, cigarette smoking, or abnormal blood lipids)

Ocular migraine (migraines that affect vision)

Shimmering, irregular spots that drift slowly across the field of vision of one eye for about 10 to 20 minutes

Sometimes blurring of central vision (what a person is looking at directly)

Sometimes a headache after the disturbances in vision

Often in young people or in people known to have migraines

Sudden, spontaneous flashes of light that can look like lightning, spots, or stars (photopsias) that occur repeatedly

Loss of vision that affects one area, usually what is seen out of the corners of the eye (peripheral vision)

Loss of vision that spreads across the field of vision like a curtain

Sometimes in people with risk factors for detachment of the retina (such as a recent eye injury, recent eye surgery, or severe nearsightedness)

Usually loss of the same parts of the field of vision in both eyes

In people with risk factors for these disorders (such as high blood pressure, atherosclerosis, diabetes, abnormal blood lipids, and cigarette smoking)

Sometimes slurred speech, impaired eye movements, muscle weakness, and/or difficulty walking

Ultrasonography of the carotid arteries

Echocardiogram (ultrasound of the heart)

Continuous monitoring of heart rhythm

Sudden loss of vision with eye pain

Severe eye ache and redness

Headache, nausea, vomiting, and sensitivity to light

Disturbances in vision such as seeing halos around lights

Measurement of pressure inside the eye (tonometry)

Examination of eye's drainage channels with a special lens (gonioscopy), done by an ophthalmologist

Often a grayish patch on the cornea that later becomes an open, painful sore

Eye ache or a foreign object (body) sensation

Sometimes in people who have an infection after an eye injury or who have slept with their contact lenses in

Culture of a sample taken from the ulcer, done by an ophthalmologist

Optic neuritis (inflammation of the optic nerve), which can be related to multiple sclerosis

Usually mild pain that may worsen when the eyes are moved

Partial or complete loss of vision

Eyelids and corneas that appear normal
