Abstract

Background and Objective: To determine whether 6.45-mu m free electron laser (FEL) energy can successfully perform optic nerve sheath fenestration and to compare the acute and chronic cellular responses with this surgery. Study Design/Materials and Methods: Optic nerve sheath fenestration was performed in rabbits by using either FEL energy (< 2.5 mJ, 10 Hz, 325-mu m spot size) or a knife. The optic nerve integrity and glial response were evaluated histologically acutely or 1 month postoperatively. Results: The FEL at low energy effectively cut the optic nerve sheaths with minimal reaction in the underlying nerve. With FEL or knife surgical techniques, a mild astrocytic hypertrophy only adjacent to the fenestration wasobserved acutely in the glial fibrillary acidic protein (GFAP)-immunoreacted sections. The chronic healing responses after either technique appeared similar with: (1) a thin fibrous scar at the fenestration site, (2) cells uniformly distributed (hematoxylin and eosin), and (3) up-regulation of GFAPand S100 beta in astrocytes adjacent to the fenestration site. Conclusion: The FEL at low energy performs an optic nerve sheath fenestration in a small space with ease. Both FEL and knife incisions cause a similar rapid glial response near the fenestration site that remains 1 month later. Lasers Surg. Med. 27:191-205, 2000. (C) 2000 Wiley Liss, Inc.
