Surgical therapy for age-related macular degeneration in the form of macular translocation, injection of tissue plasminogen activator, and gas tamponade provides some improvements in visual acuity for patients whose conditions do not respond to the anti-vascular endothelial growth factor drugs.

Fundus autofluorescence imaging, one of the modes available in a new instrument (Spectralis HRA+OCT, Heidelberg Engineering), enhances its utility as a diagnostic device and a tool for monitoring therapy of patients with retinal and macular diseases.

The model, which is based on well-established risk factors for the disease such as age, smoking, and genetics, considers high-risk, intermediate-risk, and low-risk genotypes. Genotypes are more predictive of the risk of developing advanced AMD than is age.
