What size is typically used to define the area of drusenoid PED?

The typical size used to define the area of drusenoid pigment epithelium detachment (PED) is 350 micrometers. This measurement is important in the context of age-related macular degeneration (AMD) and helps in characterizing the extent of the detachment. The significance of using this specific size is that it allows clinicians to assess the severity and potential implications of the PED in relation to the progression of AMD and the risk of developing complications such as choroidal neovascularization (CNV). Understanding this size threshold aids in clinical decision-making and monitoring of the condition over time, as changes in the size of the PED may indicate a change in disease state.
