Retinopathy

Diabetic retinopathy is the commonest cause of visual loss amongst working age people in the UK. However, it is almost completely preventable with good glycaemic control and regular retinal screening. Diagnosis is usually made on retinal screening. Management is by laser photocoagulation, good glycaemic control and there is also some role for ACE inhibition and possibly fibrate therapy.

 What is the corrected visual acuity? 

Corrected visual acuities should be recorded annually as part of the retinal screening process. This is a crude but effective way of screening for significant retinopathy that is affecting vision. However, visual acuity only tends to fall once significant retinopathy has developed.

 Is there any evidence of peripheral neuropathy?

 The presence of other microvascular complications increases the odds that the patient will develop further microvascular complications.

 What is the blood pressure?

 Hypertension is an important risk factor for retinopathy.
