What is the second stage of type III CNV?

The second stage of type III choroidal neovascularization (CNV) is characterized by sub-retinal neovascularization, which plays a crucial role in the progression of angiogenic diseases such as age-related macular degeneration (AMD). In this stage, new blood vessels begin to form in the sub-retinal space, which can lead to various complications, including bleeding, fluid leakage, and subsequent vision loss.

Understanding the progression to this stage helps in recognizing the clinical implications of CNV. Sub-retinal neovascularization often results in the accumulation of fluid in the retina, contributing to edema and distortion of the retinal architecture, which is commonly associated with visual symptoms experienced by patients.

This stage is critical in determining the appropriate management and treatment strategies for patients with CNV. Early identification of sub-retinal neovascularization can be pivotal in preventing irreversible damage and preserving visual function. Thus, sub-retinal neo formation is a key component of the type III CNV progression, underscoring its significance in the context of AMD and other retinal conditions.
