Light sensitivity
Some eye conditions may have been present before the stroke
High blood pressure can cause small blood vessels to bleed inside the eye. This then stops light from getting to the retina (which takes in the visual images at the back of the eye) and the optic nerve (which takes the visual images from the back of the eye to the back of the brain)
Diabetes can cause damage to the eye. Seek advice on control of diabetes to avoid this.
Cataracts The person may have had this eye condition before the stroke
Other conditions are common after a stroke
- Dry eyes. The blink rate may be slower after a stroke causing dry eyes. The person may be prescribed artificial tears or drops for dry eyes. For some people the eye may become very watery and will need regular gentle cleaning.
- Eye infections can happen if the person is not able to wash their hands regularly or thoroughly and then rub the eye. These infections should be treated to prevent damage to the eye. Carers can help to wash the hands or remind the person to do this themselves.
- Light sensitivity. Some people become more sensitive to light. Sunglasses or tinted lenses can help.
