Retinal stroke. Is the patient at risk?

Area of Science:

• Ophthalmology
• Neurology
• Cardiovascular Medicine

Background:

• Retinal artery occlusion (RAO) and retinal cholesterol emboli are serious vascular events.
• Prognosis for patients with these conditions requires further investigation, especially regarding long-term survival and cerebrovascular disease incidence.

Purpose of the Study:

• To evaluate the general prognosis for health and life in patients with RAO or retinal cholesterol emboli.
• To compare survivorship rates and subsequent cerebrovascular disease incidence against an age- and sex-matched population.

Main Methods:

• A follow-up study involving 86 patients with RAO or retinal cholesterol emboli who did not undergo surgery.
• Calculation of survivorship rates and incidence of subsequent cerebrovascular disease.
• Comparison of patient outcomes to expected rates in a matched control population.

Main Results:

• The overall patient group with retinal stroke showed a statistically significant decrease in survivorship from the third year.
• Patients with RAO without visible emboli had survivorship rates comparable to the control group.
• Patients with visible retinal cholesterol emboli exhibited a markedly reduced survivorship rate.
• Annual stroke mortality in the study group was significantly elevated (1,695 per 100,000), approximately four to five times higher than expected.
• Cardiovascular disease was identified as the primary cause of death.

Conclusions:

• Retinal artery occlusion, particularly with visible cholesterol emboli, is associated with a poor long-term prognosis.
• Patients with these conditions have a substantially increased risk of mortality, primarily due to cardiovascular disease.
• Early identification and management of risk factors are crucial for improving outcomes in patients with retinal vascular events.
