Spatial Patterns and Age-Related Changes of the Collagen Crimp in the Human Cornea and Sclera

Investigative Ophthalmology and Visual Science, 2018
Purpose Collagen is the main load-bearing component of the eye, and collagen crimp is a critical determinant of tissue mechanical behavior. We test the hypothesis that collagen crimp morphology varies over the human cornea and sclera and with age ...

Limbal cystotomy by fine needle aspiration of a translucent iris cyst in a horse

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old Cremello crossbred mare was referred to the Equine Veterinary Teaching Hospital of Utrecht University for a translucent iris cyst from the dorsal pupillary margin corpora nigra in the right eye. Although noninvasive diode laser treatment is the preferred method of pigmented cyst ablation, two attempts did not result in disruption ...

A Correlation Between Changes in Solar Luminosity and Differential Radius Measurements [PDF]

, 1990
Solar luminosity variations occurring during solar cycle 21 can be attributed in large part to the presence of sunspots and faculae. Nevertheless, there remains a residual portion of the luminosity variation distinctly unaccounted for by these phenomena ...

Radial and Circumferential Collagen Fibers Are a Feature of the Peripapillary Sclera of Human, Monkey, Pig, Cow, Goat, and Sheep

Investigative Ophthalmology and Visual Science, 2018
Purpose To test the hypothesis that human, monkey, pig, sheep, cow, and goat eyes exhibit circumferential, radial, and interweaving collagen architecture in the posterior sclera. Methods We analyzed 1,327 cryosections from the posterior poles of 4 human,

Primary cardiac T‐cell rich large B‐cell lymphoma causing aortic stenosis with metastasis in a Warmblood

Equine Veterinary Education, EarlyView.
Summary An 18‐year‐old Warmblood mare was presented to the Royal Veterinary College Equine Referral Hospital for investigation of progressive periocular and facial swelling, weight loss and tachycardia. Physical examination additionally identified bilateral pansystolic (grade 5/6 basilar left‐sided, 2/6 right‐sided), cardiac murmurs, submandibular ...

Hydrostatic pressure does not cause detectable changes to survival of human retinal ganglion [PDF]

, 2015
Purpose: Elevated intraocular pressure (IOP) is a major risk factor for glaucoma. One consequence of raised IOP is that ocular tissues are subjected to increased hydrostatic pressure (HP).

Gene Expression and Pathways Underlying Form Deprivation Myopia in the Guinea Pig Sclera.

Investigative Ophthalmology and Visual Science, 2018
Purpose Posterior scleral remodeling accompanies myopia. In guinea pigs developing myopia, the region around the optic nerve (peripapillary zone, PPZ) rapidly expands followed by inhibition in eye size in the periphery.

Successful use of haemoperfusion therapy in an adult horse with hepatic encephalopathy and cholangiohepatitis

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old, 520 kg, American Quarter Horse broodmare, approximately 90 days in foal, was presented to Texas A&M University Teaching Hospital for suspected liver disease. Based on clinicopathological values and hepatic abnormalities noted ultrasonographically, the mare was presumptively diagnosed with cholangiohepatitis.

Real-Time Sclera Force Feedback for Enabling Safe Robot-Assisted Vitreoretinal Surgery

Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2018
One of the major yet little recognized challenges in robotic vitreoretinal surgery is the matter of tool forces applied to the sclera. Tissue safety, coordinated tool use and interactions between tool tip and shaft forces are little studied.

Cortisol and heart rate response of mares during the in‐hand breeding procedure with and without restraint

Equine Veterinary Journal, EarlyView.
Abstract Background In‐hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objectives (1) To investigate whether the mares show increased stress responses during in‐hand breeding using (a) a ...
