➢ Non-proliferative: Microangiopathy, retinal haemorrhages and exudates (“soft” = microinfarcts, “hard” = deposits of plasma proteins and lipids), micro-aneurysms and oedema
➢ Proliferative: Process of neovascularisation and fibrosis; Vitreous haemorrhages, due to rupture of newly formed vessels → Organisation of the haemorrhage → Retinal detachment
