The elevated levels of blood pressure is called hypertension and the changes hypertension does in the retina of the eye are called hypertensive retinopathy (HTRP). Elevated levels of blood pressure harms the organs like heart, kidneys, brain and the eye. HTRP does not have any symptoms in its early stages but cause blurry vision and headache in its late stages.
HTRP has 4 stages:
1. Stage: moderately narrowed retinal arteries
2. Stage: marked narrowed retinal arteries
3. Stage: arteries look like copper wires. In artery – vene crossings vessels crush each other. Exudas can be seen in retina
4. Stage: additional to 3. Stage findings edema in optic disc occur, arteries look like silver wires, choroidal infarcts occur.
Hypertensive treatment is regulated by an internist, an ophthalmologist examines the patient for HTRP.
