Abstract

This video describes the surgical procedure to remove the two parts: palpebral and orbital of the superior lacrimal gland from a rabbit to create a dry eye disease model. This rabbit model is suitable for studies of ocular surface homeostasis, pathophysiology and ocular therapeutics.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. Use New Zealand White (NZW) rabbits weighing 2−3 kg Lightly sedate animals placed in a restraining bag with subcutaneous acepromazine as above (1 mg/kg). Remove all fur on the face and dorsal surface of the skull to visualize the surgical landmarks. Trim fur with cutting shears leaving residual fine fur about 1 mm in length. Remove all residual …
Representative Results
Figure 1: Removal of the OSLG. (A) Surgical sites are infiltrated with anesthetic using a 50:50 combination of 2% lidocaine with 1:100,000 epinephrine and 0.5% bupivacaine, which is injected into the upper lid and along the incision lines to minimize discomfort during the procedure. (B) A Colorado microdissection needle is used to incise the skin and superfi…
