What type of CNV lesion is referred to as an intraretinal RAP lesion?

The classification of choroidal neovascularization (CNV) lesions is essential in understanding their characteristics and implications for diseases like age-related macular degeneration (AMD). In this context, an intraretinal RAP (retinal angiomatous proliferation) lesion is classified as Type 3 CNV.

Type 3 CNV is characterized by the formation of new blood vessels within the retina itself, leading to the development of the RAP complex. This type of lesion typically arises from pre-existing retinal vasculature rather than originating from the choroidal supply, which distinguishes it from other types. The newly formed vessels can lead to intraretinal hemorrhages and exudates, contributing to vision impairment.

Recognizing the specific characteristics of Type 3 CNV is critical for diagnosis and treatment, as it can indicate a worse prognosis compared to other types of CNV due to the associated retinal complications. Therefore, this classification helps guide appropriate management and intervention strategies for individuals affected by such conditions.
