Table of contents
- Symptoms: sudden, painless unilateral vision loss
- First aid must be started as quickly as possible: firm pressure to the eye with the edge of a fisted hand for about 10 seconds followed by a sudden release and a pause of 10 seconds (may also be instructed to the patient over the telephone; make sure the patient has not recently undergone eye surgery or sustained an eye injury). Ocular massage may be continued (for at least 15 minutes) until other treatment is initiated.
- At the first aid centre, aspirin 250 mg may be given.
- The patient must be sent immediately to an ophthalmic emergency department. Irreversible retinal damage starts to occur 1½ hours after the occlusion.
- Aetiological investigations are started as soon as possible after the detection of the occlusion, as is done with all other disturbances of the cerebral circulation as well.
