Enfermedad cardiovascular en pacientes con oclusión arterial de la retina
Lancet (London, England)
|February 10, 1979
Resumen
Las oclusiones de la arteria retiniana tienen diferentes causas. Las oclusiones de ramas a menudo se derivan de emboli, lo que requiere una investigación sobre la arteria carótida y la enfermedad cardíaca, a diferencia de las oclusiones centrales.
Área de la Ciencia:
- Oftalmología Oftalmología.
- Neurología Neurología.
- Cardiología Cardiología.
Sus antecedentes:
- La oclusión de la arteria retiniana (ORA) puede conducir a defectos permanentes en el campo visual.
- Comprender la enfermedad cardiovascular subyacente es crucial para el manejo de la ORA.
- Diferenciar los factores etiológicos entre los subtipos de RAO puede informar las estrategias de tratamiento.
Objetivo del estudio:
- Investigar las diferencias etiológicas entre la oclusión de la arteria retiniana ramificada (BRAO) y la oclusión de la arteria retiniana central (CRAO).
- Evaluar la extensión de la enfermedad cardiovascular asociada en pacientes con ORA.
- Para determinar la importancia clínica de las lesiones de la arteria carótida en diferentes subtipos de RAO.
Principales métodos:
- Examen clínico y angiográfico de 103 pacientes con ORA.
- Comparación de los factores de riesgo cardiovascular y los hallazgos de la arteria carótida entre los grupos BRAO y CRAO.
- Evaluación de la prevalencia de hipertensión, ataques isquémicos transitorios y enfermedades del corazón.
Principales resultados:
- Los pacientes con BRAO (n = 68) mostraron tasas más altas de episodios transitorios, enfermedad cardíaca isquémica / valvular y lesiones carótidas operables en comparación con los pacientes con CRAO (n = 35).
- Los pacientes con CRAO presentaron una mayor prevalencia de hipertensión, menos ataques de advertencia, oclusiones carotídicas más completas y menos lesiones carotídicas operables.
- Se observaron diferencias etiológicas significativas entre BRAO y CRAO.
Conclusiones:
- La oclusión de la arteria retiniana ramificada es frecuentemente embolica, lo que requiere una investigación exhaustiva de las fuentes carotídeas y cardíacas.
- La oclusión de la arteria central de la retina se asocia más a menudo con la hipertensión y la oclusión carotídea completa.
- Las estrategias de diagnóstico y gestión deben adaptarse en función del tipo específico de oclusión de la arteria retiniana.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:17Ischemic Heart Disease: Overview
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
