Barth, H. , Crafoord, S. & Ghosh, F. K. (2018). Developing a retinal detachment model for in vivo testing of vitreous substitutes with repeated pars plana vitrectomy.

Pars plana vitrectomy eye surgery is sometimes done to remove eye floaters or vitreous hemorrhage inside the eyeball. In a vitrectomy, the surgeon “vacuums” out the normally clear, jelly-like fluid that fills the inside of the eye, the vitreous humor, with a surgical instrument called a vitrector.

pars pla·na | \ ˈpärs-ˈplā-nə, ˈpärz- \ Medical Definition of pars plana : the posterior part of the ciliary body extending from the pars plicata to the ora serrata — called also ciliary ring, orbiculus ciliaris The pars plana is the area located between the iris and retina, and your surgeon will make incisions in this area to gain access to your retina. By entering your eye through this area, your surgeon ensures that you don't experience any issues with your crystalline lens and your retina. The pars plana is the middle layer of the eye located in between the retina and the iris. As part of the ciliary body, it has a role in the formation of the vitreous fluid that fills the anterior portion of the eyeball. The other part of the ciliary body is pars plicata.

Depending on the condition, a vitrectomy can be performed by itself or in conjunction with other techniques. Pars plana vitrectomy is a surgery that is meant for removing the vitreous humor inside the eye. Let us take a look at the various aspects of this surgical procedure. Inside the eye, the void between the lens and the retina is filled with vitreous humor, which is a clear, viscous substance. Besides holding the retina in place, vitreous humor gives shape to the eye. The pars plana is the area located between the iris and retina, and your surgeon will make incisions in this area to gain access to your retina.

Pars Plana Insertion. A pars plana insertion of the drainage tube may be necessary during certain conditions, such as a shallow anterior chamber, aphakia, penetrating keratoplasty, vitreous in the anterior chamber, concomitant need for retinal surgery due to diabetic retinopathy or an extensive anterior staphyloma with scarring. A vitrectomy with adequate trimming of the vitreous base is required.

It is considered a safe place for making incisions, as pars plana has no specific function in post-fetal eyes.

Pars plana cysts are a common peripheral retinal pathology that do not raise much clinical concern. They do not affect the central vision and observation alone is typically recommended. Conclusion. Pars plana cysts are something to be considered when peripheral retinal elevation is noted on routine exam. It comprises the ciliary muscle and the ciliary processes and is roughly triangular in sagittal section.
