Experimental Vitreous Surgery in MonkeysIX. Pars Plana Approach in Open-Sky Techinque

Arch Ophthalmol. 1974;92(2):139-141. doi:10.1001/archopht.1974.01010010145013

A procedure is described for open-sky vitrectomy through a 170°pars plana incision. This approach permits direct visualization of the vitreous cavity and about 75% of the total fundus. It allows a more direct access to the vitreous cavity, greater surgical precision, and affords better protection to the anterior segment than the transcorneal approach. Experimental results in monkey eyes indicate that open-sky surgery through such a large incision is clinically feasible. It may be considered as an alternative procedure when extensive removal of diseased vitreous is indicated, either independently or as an adjunct to retinal surgery.
