It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or exudative/neovascular AMD. Malattia Leventinese (or Doyne’s honeycomb retinal dystrophy) is another maculopathy with a similar pathology to wet AMD.
