Health authorities are renewing warnings that high blood pressure can silently damage the eyes, reminding Fijians that hypertensive retinopathy — damage to the retina’s delicate blood vessels caused by sustained hypertension — often produces no symptoms until vision loss is advanced. The advisory stresses that regular eye and blood-pressure checks are essential because the eye can reveal early signs of vascular damage long before heart or kidney complications become apparent.
Hypertensive retinopathy occurs when chronically elevated blood pressure weakens, narrows or causes leakage from the tiny vessels that supply the retina, the light-sensitive layer at the back of the eye. Initial changes are typically painless and may not affect sight, but over time they can lead to blurred vision, loss of night vision, dark spots in the field of view and, in severe or prolonged cases, permanent vision loss. Eye examinations using a fundoscopy light or retinal camera can reveal narrowed arteries, haemorrhages or swelling that point to uncontrolled hypertension.
The renewed guidance comes amid concern about rising rates of hypertension in Fiji driven by lifestyle shifts — increased consumption of processed and salty foods, sedentary behaviour, rising obesity and diabetes, as well as alcohol and tobacco use. Many people with high blood pressure are asymptomatic and only discover the condition after complications develop, officials say, making opportunistic eye checks an important screening opportunity for broader cardiovascular risk.
Detection is straightforward in an optometrist’s or ophthalmologist’s clinic. If retinal changes consistent with hypertension are found, patients are referred for medical assessment and blood-pressure management. While there is no medication that directly reverses retinal damage, controlling systemic blood pressure, addressing diabetes and lowering cholesterol can halt progression and reduce the risk of further sight deterioration. In advanced cases where vision is already affected, hospital-based interventions such as laser therapy or intravitreal injections may be required, but these are typically reserved for long-standing, severe disease.
Prevention advice mirrors standard cardiovascular health recommendations: more fresh fruits, vegetables and local foods; reduced salt, sugar and processed fats; regular physical activity such as walking or community sports; avoidance of tobacco; moderation of alcohol; and maintaining a healthy weight. Regular screenings for blood pressure and blood sugar, together with periodic eye examinations, are urged — particularly for those with a family history of hypertension, diabetes, or known cardiovascular disease.
This advisory is principally a public health reminder rather than an announcement of new research or policy, reiterating established clinical guidance that early detection and management of hypertension protect both general health and eyesight. Health services across Fiji are being encouraged to promote routine eye checks as part of primary care visits, and communities are being urged to make eye care a regular element of personal health routines to prevent avoidable blindness.
