Objective- To find normal value of thickness of the lens capsules in domesticated rabbits by ultrasonography. Design- experimental in vivo study and clinical trial. Animals- Twelve matured and immature domesticated rabbit. Procedures- The eyes of 12 non anaesthetized domesticated rabbits were sonograophed using a linear 6-12 MHz high frequency transducer. The thickness of anterior and posterior...

As the first case, a baby red eared slider turtle, Trachemys scripta elegans, 1.77 inches long, with a 4 month history of anorexia and blind eyes was referred to the Aquatic Animal Clinic, School of Veterinary Medicine, Shiraz University, Iran. The eyes of the pet were swollen and he was not active in swimming and feeling around. In the clinic, after stress treatment, he was kept in a clean aqu...

A 10-year-old, male Rottweilerdog was presented to Small Animal Hospital of Tehran University with a history of lethargy, anorexia, weight loss, vomiting, polyuria, polydipsia and blindness. The dog showed symptoms of depression, high body temperature (39.2 ˚C), tachypnea (40 breaths min-1) and cachexia. In ophthalmic examination, bilateral hyphema (hemmorrahge in anterior chamber of...

Dry eye from Sjögren's syndrome is a multifactorial disease that results in dysfunction of the lacrimal functional unit. Studies have shown changes in tear composition, including inflammatory cytokines, chemokines, and metalloproteinase. T-lymphocytes have been shown to increase in the conjunctiva and lacrimal glands in patient and animal models. This inflammation is in part responsible for the...

In developing countries, household air pollution (HAP) resulting from the inefficient burning of coal and biomass (wood, charcoal, animal dung and crop residues) for cooking and heating has been linked to a number of negative health outcomes, mostly notably respiratory diseases and cancers. While ocular irritation has been associated with HAP, there are sparse data on adverse ocular outcomes th...

An apparatus and a method for rapidly determining chemical toxicity have been evaluated as an alternative to the rabbit eye initancy test (Draize). The toxicity monitor includes an automated scoring of how motile biological cells (Tetrahymena pyriformis) slow down or otherwise change their swimming patterns in a hostile chemical environment. The method, called the Motility Assay (MA), is tested...

We compiled data from the literature and colleagues to examine the relationship between eye axial length and body weight for vertebrates as well as birds, mammals, reptiles, and fishes independently. After fitting the data to logarithmic and semi-logarithmic models, we found that axial length of vertebrate eyes does obey a conventional logarithmic relationship with body weight rather than a sem...

in order to find a reference values of intra ocular pressure (lop) in the normal male and tamale dogs on the basis of sizes ages, a research project were conducted. for this purpose, during one year (1992-1993), the lop of total 360 dogs (180 males and 180 females. either large of small sizes) refered to the small animal teaching hospital of tehran university were measured by shiotz tomometer. ...

Submit Manuscript | http://medcraveonline.com posterior segment FBs is derived from metal fragments. A vegetative FB such as wood may reach inner part of eye but is located usually in the anterior segment [3,4]. Animal matter such as cilia can be carried along with denser matter to the posterior segment [1,2,5]. Ocular damage caused by intraocular foreign bodies (IOFB) can occur by two mechanis...

Ocular motor behavior is dictated by visual demands. The entire brain is involved in programming and executing of eye movements. Gaze shifts performed under natural conditions require an elaborate supranuclear coordination between various motor and sensory mechanisms. Recently, a wealth of novel data emerging from animal studies along with functional imaging in humans expanded and modified trad...
