Reference Intervals for Schirmer Tear Test and Intraocular Pressure in Healthy Hamdani Crossbred Sheep

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study establishes reference intervals for Schirmer tear test (STT) and intraocular pressure (IOP) in healthy Hamdani crossbred sheep. STT values were lower and IOP values higher than previously reported, highlighting the importance of breed‐specific reference ranges in clinical ophthalmic evaluation.

Characterization of Pupillary Light Response through Low-Cost Pupillometry and Machine Learning Techniques

Eng
This article employed pupillometry as a non-invasive technique to analyze pupillary light reflex (PLR) using LED flash stimuli. Particularly, for the experiments, only the red LED with a wavelength of 600 nm served as the light stimulation source.

Hyaluronic Acid‐Based Photocurable Glue Application as an Alternative Surgical Approach for Corneal Injuries in Canine Patients: A Case Series

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
• Hyaluronic acid (HA)–based photocurable glue was applied to deep corneal injuries in dogs as a minimally invasive alternative when surgery was not feasible. • The adhesive was delivered to the lesion and rapidly photocrosslinked using 405 nm visible light, creating a stable protective barrier.

New Observations Regarding the Anatomy of the Pupillary Light Reflex: Animal Studies

, 1999
In humans and other primates, an increase in luminance in either eye elicits bilateral pupilloconstriction that is essentially equal in both eyes. Our current thinking regarding the subcortical pathway for this pupillary light reflex owes much to the ...

Two Cases of Fibrin Membrane‐Induced Pupillary Block Treated With Neodymium‐Doped Yttrium Aluminium Garnet (Nd:YAG) Laser After Cataract Surgery in Dogs

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study evaluates the clinical efficacy of Nd:YAG laser membranotomy in dogs with fibrin membrane‐induced pupillary block (FMPB). Targeted application of the Nd:YAG laser safely disrupts the obstructive pupillary membrane, thereby restoring normal aqueous humour outflow and effectively resolving secondary intraocular pressure (IOP) elevation without

Ocular Manifestations of Canine Parvovirus in Juvenile Dogs: Tear Production, Intraocular Pressure, Fundoscopic Findings, and Ultrasonographic Measurements

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Naturally acquired canine parvovirus infection in juvenile dogs was associated with reduced tear production, ocular hypotony, corneal epithelial defects, and fundoscopic abnormalities, suggesting ocular surface and posterior segment involvement and supporting ophthalmic screening during clinical evaluation.

PupilMetrics: a support system for preprocessing of pupillometric data and extraction of outcome measures

Scientific Reports
The rapid pupillary constriction to an abrupt light stimulus is signaled through an oligosynaptic neural pathway that dominates over other supranuclear influences on pupillary movement.
