They thought that it was associated with iatrogenic or thick preretinal membrane's tangential tractional force over the fovea and absorption of sub-ILM deposits.

Although pretreatment with anti-VEGF agents may reduce bleeding tendency during the operation, it may also aggravate the tractional force of the fibrovascular tissue, and thus it should be judiciously used in eyes with fibrous components.
