Plain-English summary
A group of dogs underwent various treatments for eye problems, specifically looking at the Meibomian glands that help keep their eyes moist. They had scans done before and after partial tarsal plate excision (a surgical procedure), cryotherapy (freezing treatment), and laser therapy. The results showed that while the volume of these glands decreased slightly after treatments, the overall number and structure remained mostly unchanged. This suggests that while the treatments may affect gland volume, they do not significantly alter the number of glands present.

Abstract
OBJECTIVE: To determine the morphology and volume of Meibomian glands (MG) of dogs with microCT before and after partial tarsal plate excision (PTPE), cryotherapy, and laser therapy. PROCEDURE: MicroCT scans were made of 12 upper lids (ULs) and lower lids (LLs) of 12 dogs. After undergoing PTPE, 10 ULs and LLs were scanned again, and one UL and one LL was scanned after laser therapy and one UL and one LL after cryotherapy. RESULTS: The length of the area containing MGs did not change pre- and post-PTPE, and cryo- or laser therapy. The mean number of MGs in the ULs and LLs was 30.50 and 29.42, respectively, and did not change during the procedures. The average length of one individual MG was 2.60 mm. The mean volume of MGs in the 10 ULs and LLs pre-PTPE was 21.45 and 17.2 mm, respectively, and 12.84 and 11.25 mmin the UL and LL after PTPE, respectively. The mean volume of MGs decreased from 29.78 mmprecryotherapy to 28.91 mmpost-treatment and in the lower eyelid from 22.87 to 22.4 mmafter cryotherapy. The mean volume of MGs in the UL and LL before laser therapy was 8.95 and 6.78 mm, respectively, and after 9.25 and 6.38 mm, respectively. CONCLUSION: MicroCT is a valuable tool to determine the morphology and the volume of MGs and to demonstrate changes that occur after PTPE, laser-, and cryotherapy. There is no need for additional preparation, such as staining, of the specimen prior to scanning.
