Choroidal ruptures can lead to which type of choroidal neovascularization?

Choroidal ruptures are often associated with trauma to the eye that can result in damage to the retinal pigment epithelium (RPE) and the underlying choroidal structures. This damage can create conditions that are conducive to the formation of choroidal neovascularization (CNV), specifically Type 2 CNV.

Type 2 CNV occurs when new blood vessels grow from the choroid towards the outer retina, breaking through Bruch's membrane and the RPE. This type of CNV is particularly linked to instances where there is significant disruption of the anatomical layers, such as that seen in choroidal ruptures. Here, the underlying pathology of traumatic rupture results in an inflammatory response that facilitates the growth of these new vessels.

The presence of Type 2 CNV typically leads to a more severe clinical presentation and can contribute to vision loss due to the potential for leakage and hemorrhage. Understanding the relationship between choroidal ruptures and Type 2 CNV is crucial for managing patients with these conditions effectively and anticipating potential complications arising from the neovascular process.
