Experimental posterior penetrating eyeinjury in therhesus monkey: vitreous-lens admixture

SUMMARY A standardised experimental posterior penetrating eyeinjury intherhesusmonkey withthevitreous-lens admixture resulted inlimited fibrous ingrowth fromthewoundandminimal traction on theperipheral retina. Microscopically inflammation was notedintheiris, ciliary body, andasaperivascular infiltrate oftheinner retina. Periretinal membranes didnotoccur,andcellular proliferation within thevitreous was lessmarkedthanobserved after an identical woundand simulated vitreous haemorrhage inpreviously reported studies. Thelensmay bea lessimportant stimulus tointravitreal fibroblastic proliferation thanpreviously assumed.
