Surgical aphakia ( cataract removal) and pseudophakia (lens implant) Tractional retinal detachment occurs when the vitreous pulls the retina, such as from:Įxudative retinal detachment occurs with fluid accumulation in the subretinal space, such as from: Posterior vitreous detachment (most common)Ĭauses of non-rhegmatogenous retinal detachment include tractional and exudative. Rhegmatogenous retinal detachments are more common, with the primary causes being: The interplay between vitreoretinal traction and predisposing retinal lesions is associated with retinal detachment. Retinal detachments are classified as rhegmatogenous, meaning caused by a tear (rhegma) in the retina, or non-rhegmatogenous. Retinal detachment is often associated with:
Observational studies with sample sizes >300 showed a median annual incidence of 1 in 10,000 6. Rhegmatogenous retinal detachment is most common in the 6th and 7th decade of life but can occur at any age and has a slight male predilection 5. Tractional retinal detachment: secondary to retinal fibrosisĮxudative retinal detachment: due to choroidal tumors causing increased flow through the subretinal space Lattice degeneration: circular retinal holes or atrophic holes Retinal break: full-thickness defect in the neurosensory retina, which can be caused by trauma or inflammation Rhegmatogenous retinal detachment: fluid ingression from the vitreous cavity to the subretinal space causing retinal separation (most common)
There are numerous subtypes of retinal detachment 5:
