Histopathologic findings in human eyes after pars plana vitrectomy and lensectomy
H. Buettner and R. Machemer
Six eyes, four obtained at autopsy and two enucleated for neovascular
glaucoma, were studied histopathologically between one week and 3 1/2 years
after pars plana vitrectomy (some combined with lensectomy) for
proliferative diabetic retinopathy. Fibrovascular proliferation at the
sclerotomy site was minimal. Lensectomy through the pars plana proved to be
quite complete. A cyclitic membrane was found in eyes with postoperative
rubeosis irides. Excision of the vitreous from the posterior part of the
vitreous cavity was quite complete except for remnants of stalks and
membranes on the retinal surface.
