Diabetic retinopathy screening allows for opportunistic identification of other lesions, a common example are venous and arterial occlusions. Occlusions may affect the whole of the retina (central) or just part of the retina (branch). If the occlusion involves the central retinal vision may be affected. There are a number of risk factors associated with retinal occlusions which include high blood pressure and cholesterol levels as well as obesity and smoking. It is therefore important that patients who present with occlusions are managed appropriately so these risk factors can be assessed.
The purpose of the audit is to assess whether specialist referral to an ophthalmic medical clinic is worthwhile.
