Abstract

Abstract: : Purpose: Evaluate the histopathologic features in the optic nerve head of rabbit eyes after pars plana vitrectomy and Lamina Cribrosa Puncture with and without Optic Nerve Canula insertion. Methods: We performed three port pars plana vitrectomy and Lamina Cribrosa Puncture with a fine zaphire tip (360 microns) in 6 rabbit eyes. A non biodegradable plastic canula 800 microns long was introduced at the puncture site in three of them. The purpose of the canula insertion was to produce a shunting between vitreous cavity and subaracnoidal space or intraorbital space. Results: There were no complications in the procedure. After one, two and four weeks, the eyes were enucleated and histopathologic study was performed. Histopathological features consisted of an artificial excavation of the optic nerve from the vitreous to retrolamellar portion. In the eyes that were enucleated during the first and second week, there was different degrees of inflammatory infiltrate composed of lymphocytes and plasma cells above the optic nerve head. In the last group, gliosis and reactive fibroblasts were observed. The histopathological features of the eyes with and without the optic nerve plastic canula were very similar. Conclusions: An artificial comunication in the optic nerve from the vitreous to retrolamellar portion was demonstrated after lamina cribrosa puncture. Scaring process and inflamatroy response was not different in eyes with and without insertion of Optic Nerve Canula.
