[Life expectancy of patients with circulatory disorders of the posterior eyeball segment]
Insights
Patients with central retinal or branch artery occlusion face higher mortality rates, particularly those with hypertension. This suggests hypertension may indicate progressive atherosclerosis, a major cardiovascular risk factor.
Area of Science:
- Ophthalmology
- Cardiology
- Vascular Medicine
Context:
- Circulatory disorders affect patient mortality.
- Assessing mortality risk in specific vascular conditions is crucial.
Purpose:
- To determine the mortality rate of patients with circulatory disorders.
- To compare patient mortality with the general population.
- To identify specific circulatory conditions associated with increased mortality.
Summary:
- A study of 155 patients with circulatory disorders found no excess mortality in central retinal vein occlusion or ischemic optic neuropathy.
- However, patients with central retinal or branch artery occlusion exhibited a statistically significant increased mortality rate.
- This increased risk was specifically observed in hypertensive patients, not normotensive ones, suggesting a link to progressive atherosclerosis.
Impact:
- Identifies central retinal or branch artery occlusion, especially in hypertensive individuals, as conditions with elevated mortality risk.
- Highlights the critical role of hypertension as a cardiovascular risk factor.
- Suggests potential links between vascular occlusions, hypertension, and atherosclerosis progression.
Abstract:
Based on the method of person-years, the morality rate of 155 patients with circulatory disorders was calculated and compared with the death rate of an age-matched general population. No excess mortality was found among 53 patients with central retinal vein occlusion and among 58 patients with ischemic optic neuropathy. On the other hand, 44 patients with central retinal or branch artery occlusion showed a statistically significant increased mortality rate. Patients with arterial circulatory disorders were subdivided into hypertensives and normotensives; an increased mortality rate was seen only among patients with hypertension but not among patients with normal blood pressure. Hypertension is one of the main cardiovascular risk factors. The increased mortality risk among our patients with hypertension may be indicative of a progressive atherosclerosis.
