A 2-year-old New Zealand White rabbit is scheduled for ocular examination under sedation. You are evaluating the effects of sedation on intraocular pressure (IOP) and tear secretion (TS). According to recent findings, what is the expected impact of intranasal (IN) versus intramuscular (IM) administration of a butorphanol and zolazepam-tiletamine (ZT) combination?
A. IN administration significantly increases IOP and TS compared to IM
B. IM administration significantly reduces IOP but not TS compared to IN
C. Both IN and IM routes have no significant effect on IOP and TS
C. Both IN and IM routes have no significant effect on IOP and TS
You are comparing tonometry methods in Mini Lionhead rabbits. Which of the following is true regarding IOP measurement using the TonoVet Plus® versus Tono-Pen Avia®?
A. TonoVet Plus® yields lower IOP values than Tono-Pen Avia®
B. TonoVet Plus® requires topical anesthesia for accurate results
C. TonoVet Plus® provides significantly higher IOP values than Tono-Pen Avia®
C. TonoVet Plus® provides significantly higher IOP values than Tono-Pen Avia®
In a murine model of experimental autoimmune uveoretinitis (EAU), what effect does anti-CD40 monoclonal antibody treatment have on disease progression?
A. It increases CD40+ dendritic cells and TNF-α production
B. It decreases CD40+ MHC-II+ dendritic cells and IRBP-specific lymphocyte proliferation
C. It enhances MHC-II expression and inflammation severity
B. It decreases CD40+ MHC-II+ dendritic cells and IRBP-specific lymphocyte proliferation

B. Immunohistochemistry confirms presence of red/green and blue cones
C. Histology shows absence of photoreceptor layers
B. Immunohistochemistry confirms presence of red/green and blue cones
In a study on sugar gliders, which of the following statements regarding ocular diagnostics is correct?

C. STT II and PRTT provide little clinical value in sugar gliders
C. STT II and PRTT provide little clinical value in sugar gliders
What was the primary finding when comparing BAMH treatment to EDTA and PBS in ex vivo rabbit corneal wounds?
