Hereditary glaucoma in Shiba Inus due to pectinate ligament dysplasia?
A very interesting study, although Shiba Inu dogs are not too popular in Europe. But at least the Japanese dogs of this breed seem to be predisposed to develop glaucoma - and a dysplasia of the pectinate ligament seems to be a plausible explanation for this.

The purpose of the study was to describe the shape of the pectinate ligament (PL) and to estimate the width of the iridocorneal angle (ICA) in glaucomatous and nonglaucomatous eye of Shiba Inu dogs in Japan.

One hundred fourteen Shiba Inu dogs were presented to the Veterinary Medical Center at the University of Tokyo between June 1998 and June 2003.

Among these, 46 dogs had glaucoma; the remaining 68 dogs were presented for routine vaccinations or heartworm testing and were used as a control population.

Complete ophthalmic examination and gonioscopy were performed in all the dogs.
PL and ICA were evaluated by gonioscopy and goniophotographs.
Of the 46 dogs with glaucoma, 17 (37%) were affected bilaterally, and 29 (63%) were affected unilaterally.
Of the 29 dogs with unilateral glaucoma, the ICA of the normotensive eye was slightly narrow in 2 eyes (7%), narrow in 12 eyes (41%), and closed in 15 eyes (52%).
Among the normotensive control group, the ICA was open in 13 dogs (19%), slightly narrow in 29 (43%), narrow in 22 (32%), and closed in 4 (6%).

In dogs with narrow and slightly narrow ICAs, the PLs were thickened, and in some cases, formed a solid sheet.

The majority of dogs with glaucoma had changes in both ICA and PL.

A narrow or slightly narrow ICA was also detected in the majority of normotensive control dogs.

This study suggests that ICA narrowing and PL thickening is a common abnormality in Shiba Inu dogs in Japan and may predispose those dogs to glaucoma.

Variability of SDMA in apparently healthy dogsmembers
Symmetric dimethylarginine (SDMA) is a screening tool for early kidney dysfunction and monitoring treatment in cases of chronic kidney disease (CKD). There are no current studies describing the suitability of this test for use with published population‐based reference intervals. The objectives of this study were to determine the components of biological variability, the index of individuality (IOI), the critical difference between sequential measurements (CD) and the number of measurements required to assess the homeostatic set point (HSP), for both SDMA and serum creatinine (sCr), in apparently healthy dogs.
