Patients with wet macular degeneration develop new blood vessels under the retina. This causes hemorrhage, swelling, and scar tissue but it can be treated with laser in some cases. Dry macular degeneration, although more common, typically results in a less severe, more gradual loss of vision. There is no proven medical therapy for dry ARMD. Laser photocoagulation can be done in selected cases of the wet type. It usually does not restore lost vision, but it may prevent further loss. Recently, photodynamic therapy has proven to be effective in stopping abnormal blood vessel growth in some patients. Early diagnosis is critical for the successful treatment of wet macular degeneration.
Types :
Wet (neovascular) : New delicate vessels form, which can bleed
Dry (non-neovascular) : Characterized by drusen and loss of pigment in the retina
