Recent advances in imaging technology -- for example, the advent of autofluorescent and infrared imaging -- are now allowing retina spe-cialists and researchers to more readily identify posterior segment irregularities that may affect vision at an earlier stage. In particular, retinal sensitivity as measured by microperimetry can be significantly reduced in a particular subgroup of patients with neovascular age-related macular degeneration (AMD), despite comparable visual acuity. Similarly, indocyanine green chorioan-giography is emerging as an important tool to identify polypoidal choroidal vasculopathy, par-ticularly in Asian patients who have neovascular AMD. While level 1 evidence has not yet been published, some clinicians believe the use of fluo-rescein angiography can help predict a patient's prognosis and required number of antivascular endothelial growth factor injections necessary to retain vision. These types of imaging advances will allow retina specialists to further tailor treat-ment for each individual patient.
