What is non-rhegmatogenous retinal detachment primarily caused by?

Non-rhegmatogenous retinal detachment is primarily caused by vitreous traction or leakage exudation. This type of retinal detachment occurs not due to a tear in the retina, which is characteristic of rhegmatogenous detachment, but through mechanisms involving the vitreous gel that adheres to the retina.

In non-rhegmatogenous cases, traction forces from the vitreous can pull on the retina, leading to its detachment without any associated breaks or tears. Additionally, conditions that lead to fluid exudation beneath the retinal layer, such as inflammatory processes or vascular issues, can also contribute to this type of detachment.

Understanding the role of vitreous traction is crucial in diagnosing and managing retinal detachments, as it highlights the need for addressing underlying vitreous gel abnormalities to prevent further complications.
