Severe Hypertensive Retinopathy Presenting as Bilateral Vision Loss Patient Presentation

Abstract

Background: The retina provides a unique in vivo diagnostic window into systemic microvasculature. Severe hypertensive retinopathy is a critical prognostic indicator for acute target-organ damage and signifies a high risk for life-threatening cardiovascular and cerebrovascular events.

Case Presentation: A 48-year-old male presented with a two-month history of progressive, painless bilateral vision loss and frequent morning headaches. Clinical examination revealed a significantly elevated blood pressure of 210/120 mmHg and reduced visual acuity (20/40 OD, 20/60 OS). Dilated fundoscopy demonstrated classic signs of severe hypertensive retinopathy, including widespread arteriolar narrowing, flame-shaped hemorrhages, cotton-wool spots, and mild optic disc edema.

Management and Outcome: The presence of optic disc swelling and severe hypertension prompted immediate referral to the emergency department for a hypertensive emergency. The patient was treated with a carefully titrated intravenous antihypertensive regimen. At a 3-month follow-up, his blood pressure was well-controlled on oral medications, visual acuity improved to 20/25 bilaterally, and fundoscopic examination revealed complete resolution of the retinal hemorrhages and cotton-wool spots.

Conclusion: This case highlights the critical importance of routine fundoscopic evaluation in patients with undiagnosed or poorly controlled hypertension presenting with visual disturbances. Rapid recognition of severe hypertensive retinopathy and immediate medical intervention can successfully reverse visual deficits and mitigate severe systemic morbidity.
