Submacular hemorrhage managed by surgical displacement

May 15, 2002

Thick submacular hemorrhage (SMH) in patients with age-related macular degeneration (AMD) typically presents suddenly, with dramatic loss of central vision. The natural history of untreated SMH is poor. Proposed mechanisms of damageinclude iron-induced outer retinal toxicity, mechanical obstruction of metabolic exchange, and shearing of photoreceptors by the adherent and contractile blood clot.
