Age-associated macular degeneration (AMD) categorizes into two varieties that include the non-neovascular atrophic type called “dry” macular degeneration along with the neovascular sort that is known as “damp” macular degeneration. Dry AMD demonstrates characteristic lesions of the RPE due to the build-up of mobile particles named lipofuscin, which, subsequently, causes the development of the pathognomonic yellowish, amorphic deposits called drusen between the RPE and the fundamental the Bruch membrane.
Dry macular degeneration is characterised because of the gradual thinning of the macula as well as the formation of little yellow protein clumps (drusen).ten The presence of huge drusen signifies much more Innovative macular degeneration.

Department retinal artery occlusions (BRAO) normally arise temporally at branching points among more compact vessels with the central retinal artery and account for roughly 38% of all acute retinal occlusions.[29] BRAO has superior visual prognosis than CRAO.[29][thirty]
Spherical hole retinal detachment is usually surgically repaired by laser demarcation which encourages adhesion between the neural retinal levels as well as retinal pigment epithelium.
