Classification
The disease is classified according to types of lesions detected on fundoscopy into non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). Diabetic retinopathy affect both eyes in parallel. NPDR is subdivided into mild and moderate-to-severe forms.
Mild NPDR
- Microaneurysms
- Dot and blot hemorrhages
- Hard (intra-retinal) exudate
Moderate-to-severe NPDR
Is mild NPDR plus:
- Cotton-wool spots
- Venous beading and loops
- Intraretinal microvascular abnormalities ( IRMA )
PDR
- Neovascularization of the retina, optic disc or iris
- Fibrous tissue adherent to vitreous face of retina
- Retinal detachment
- Vitreous hemorrhage
- Pre-retinal hemorrhage
Some people develop a condition called macular edema. It occurs when the damaged blood vessels leak fluid and lipids onto the macula. The fluid makes the macula swell, which blurs vision.
