What is the first stage in the development of type III CNV?

In the development of type III choroidal neovascularization (CNV), the first stage involves IRNeovascularization, or intraretinal neovascularization. This process typically occurs when aberrant blood vessels begin to grow within the retinal layers, specifically arising from the inner retina.

This initial stage is crucial as it sets the stage for subsequent developments, including the formation of more complex neovascular networks that can eventually lead to CNV. Specifically, in type III CNV, intraretinal neovascularization can precede sub-retinal neovascularization, illustrating a progression that influences the clinical presentation and treatment approaches of the condition.

Understanding this initial stage is important for recognizing how neovascular pathology develops, leading to potential complications such as vision loss in patients with retinal diseases, particularly in conditions like diabetic retinopathy and certain forms of age-related macular degeneration (AMD). The relationship between IRNeovascularization and the later formation of CNV highlights the significance of early detection and management of intraretinal changes to prevent further retinal damage.
