Which type of CNV is characterized as occurring in the subretinal space?

Type 2 choroidal neovascularization (CNV) is specifically characterized by the presence of new blood vessels that develop in the subretinal space. This type of CNV is often associated with conditions such as age-related macular degeneration (AMD), where the new vessels breach the retinal pigment epithelium (RPE) and invade the neuroretinal layers. Understanding the subretinal location is critical, as it influences the clinical presentation and potential treatment strategies for the condition. In contrast, other types of CNV, such as Type 1 and Type 3, are associated with different anatomical relationships concerning the retinal layers and the RPE, which can affect their management and outcomes. Hence, identifying Type 2 as the variant occurring specifically in the subretinal space is essential for clinical diagnostics and therapeutic interventions.
