Obtaining maximal optic nerve length during enucleation procedures

Arch Ophthalmol. 2000 Jan;118(1):70-3. doi: 10.1001/archopht.118.1.70.


Objective: To determine optimal scissor blade design and surgical approach to facilitate obtaining a long optic nerve segment during enucleation procedures.

Methods: Two hundred mock enucleations were performed with the use of a human child skull model and a silicone sphere to simulate an eye. Temporal and nasal approaches with scissor blades with noncurved, mildly curved, or strongly curved blades were tested.

Results: Longer optic nerve segments were obtained with mildly curved scissor blades from both temporal and nasal surgical approaches. Strongly curved scissor blades uniformly produced smaller specimens.

Conclusions: Mildly curved scissors should be used for enucleation when a long optic nerve specimen is desired. Strongly curved scissors should be avoided.
