Prevalence of AMD increases with age. Nonexudative AMD is the most common form of AMD. Factors associated with AMD include increased age, heredity, photic injury, nutrition, toxic insults, and cardiovascular risk factors. High-risk characteristics of drusen for development of CNV include: soft drusen, large drusen, greater than five drusen, confluence, and focal hyperpigmentation. Disappearance of drusen can occur spontaneously or may follow laser to drusen (CNVPT and PTAMD). Disappearance of drusen may result in geographic atrophy. Monitoring visual acuity and visual symptoms for the progression of AMD is of utmost importance in applying timely treatment.
