Abstract:

The preretinal macular membrane is divided into idiopathic and secondary types. The formation mechanism of idiopathic preretinal macular membrane is not very clear. Aging, female gender and other factors are believed to play a role in its formation. In the case of retinal damages, especially neglected damages, for example, concussion of the retina may occur during concussion, idiopathic preretinal macular membrane is formed in the process of retinal repaire. The formation mechanism of secondary preretinal macular membrane includes injury, inflammatory reaction, and retinal ischemia. By studying the mechanism of formation of idiopathic and secondary preretinal macular membrane, it is beneficial to prevent and treat the preretinal macular membrane better.(Int Rev Ophthalmol, 2019, 43:  118-122)
