Study Notes
Retinopathy Overview
- Retinopathy involves microvascular damage to the retina, leading to blurred vision and potential progressive vision loss.
- The condition can develop either slowly over time or rapidly, impacting individuals significantly.
Risk Factors
- Most frequently occurs in adults suffering from diabetes or hypertension.
- Diabetic retinopathy is a prevalent complication in patients with prolonged, uncontrolled diabetes.
Types of Diabetic Retinopathy
- Nonproliferative retinopathy is the most common form, characterized by:
- Capillary micro-aneurysms
- Retinal swelling
- Hard exudates
- Macular edema indicates worsening retinopathy due to leakage from macular blood vessels.
- Weakening capillary walls may rupture, causing “dot or blot” hemorrhaging, resulting in severe loss of central vision.
- As the disease progresses, proliferative retinopathy can develop:
- Characterized by the growth of abnormal and fragile new blood vessels that are prone to leakage, leading to significant vision impairment.
Hypertensive Retinopathy
- Arises from blockages in the retinal blood vessels caused by hypertension.
- Initially, changes may not impact vision, but can be detected during routine eye exams via:
- Retinal hemorrhages
- Anoxic cotton-wool spots
- Macular swelling
- Severe, sustained hypertension can result in sudden vision loss due to swelling of the optic disc and nerve (papilledema).
Treatment
- Management is crucial and may require emergency care.
- Effective treatment of hypertension can often restore normal vision.
