During vitrectomy, where are the sclerotomy incisions made?

During vitrectomy, sclerotomy incisions are specifically made through the pars plana, which is a region located in the peripheral retina and is part of the uveal tract of the eye. The pars plana is chosen for these incisions because it minimizes damage to the surrounding structures and provides adequate access to the vitreous cavity. This access is essential for removing the vitreous gel and addressing various retinal conditions.

Incisions through the pars plana allow for direct entry into the vitreous cavity while maintaining the integrity of the eye, helping to reduce the potential for complications that can arise from incisions in other areas, such as the cornea or anterior chamber. These other areas may face increased risks such as bleeding, infection, or damage to the lens or iris, making the pars plana the safest and most efficient access point during vitrectomy procedures.
