Hypertensive Retinopathy



Hypertensive Retinopathy Causes


Sustained hypertension often targets the retina (along with other organs). When a patient is exposed to excessive long-term hypertension, the small blood vessels in the eye become damaged. These vessels also thicken, bulge, or leak.


Hypertensive Retinopathy Definition


Hypertensive retinopathy is characterized by retinal damage that results from hypetension or high blood pressure.


Hypertensive Retinopathy Diagnosis


In diagnosing hypertensive retinopathy, fluorescein angiography, ophthalmoscopy, and sphygmomanometry may be used. Fluorescein angiography examines the circulation of the retina through a dye tracing method. An ophthalmoscope instrument is used to evaluate if the condition of the retina and the vitreous humor. Lastly, a sphygmomanometer is used to measure the patient's blood measure. This is particularly important because decreasing hypertension is an important strategy in treatment.


Hypertensive Retinopathy Symptoms and Signs


Patients afflicted with hypertensive retinopathy may not exhibit any visual cues. However, a decreased vision or repeated headaches may be indicative of retinal damage. Arteriosclerotic changes, such as bilateral arteriolar narrowing, may also pinpoint hypertensive retinopathy. Other symptoms include ischemic changes, hemorrhages, edema around the retina, papilledema, and visual acuity loss.


Hypertensive Retinopathy Treatment


Treating hypertensive retinopathy usually involves limiting, reversing, or preventing further damage on the retina by decreasing the affected patient's blood pressure. Regular eye examinations are also important to monitor the healing process.
