Eyes, pupils different size
Alternative names:
anisocoria; enlargement of one pupil; pupils of different size
Home care:
Treatment depends on the cause of the enlargement of one pupil. - For pupil size inequality caused by a head injury, get immediate medical help.
- For pupil size inequality caused by a tumor, follow prescribed therapy. Stay active as strength allows. Work and exercise moderately. Rest when tired.
- For pupil size inequality caused by meningitis or encephalitis, follow prescribed therapy and rest in bed in a darkened room.
- For pupil size inequality caused by acute glaucoma, avoid emotional upset, which raises pressure in the eye. Don't smoke. Tobacco constricts blood vessels, reducing the blood supply to the eye. Follow prescribed therapy that may include eye drops to lower pressure inside the eye, diuretics to decrease fluid pressure in the eye, or pain relievers. After treatment, resume normal activities, but avoid fatigue. A low-salt diet is recommended.
