PURPOSE In chickens, there are circadian rhythms in axial length, choroidal thickness, and intraocular pressure (IOP), the phases of which differ, depending on visual manipulations that alter ocular growth rate. In this study, these same rhythms were sought in the common marmoset, a primate model of eye growth, to establish whether these may play a role in ocular growth regulation across specie...

Ocular metastases of solid tumors are very rare, but in most of them (~45-70% of all detected ocular metastases) the primary site of origin is the breast [1, 2]. Ocular metastases of breast cancer appear frequently without previous dissemination to organs even those in close proximity. Thus, occurrence of ocular metastases may be the characteristic feature of a special subgroup of breast cancer...

introduction and aims: prior investigators have proposed microlithiasis as a causative factor for occult gallbladder diseases. endoscopic ultrasonography (eus) is potentially far more sensitive than transabdominal ultrasonography (tus) in visualizing small stones. the aim of this study was to investigate the role of endoscopic ultrasounography (eus) in the diagnosis of microlithiasis in patient...

A 65–yrs-old man referred for an ocular discomfort and red eye. The clinical diagnosis was leech in the left eye and its species confirmed as being Limnatis nilotica. Ocular leech infestation should be considered in patients with a history of swimming or washing their face in streams and lakes.

AIM To analyze the application significance of ultrasound contrast agent in identification and diagnosis of ocular spaceoccupying lesions, and mainly analyze its advantages and problems. METHODS Thirty-two representative literatures about the application of ultrasound contrast agent in diagnosis of spaceoccupying lesions at home and abroad were collected after focused on sorting the literatur...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

Background: Rheumatoid Arthritis patients are evaluated during treatment for various inflammatory factors such as C-reactive protein, Erythrocyte Sedimentation Rate, and Disease Activity Score, and other immune system-related factors. In the follow-up of patients with rheumatoid arthritis, hematologic factors associated with the immune system especially Platelet to Lymphocyte Ratio and Neutroph...

The aim of this study was to determine the prevalence and type of ophthalmic diseases among horse populations in the suburbian riding clubs of Tehran. Ophthalmologic examinations were performed in 901 horses and ocular lesions were diagnosed in 40 (4.4%) animals. In the 54 eyes of these horses that had ocular defects, 103 ocular abnormalities were detected. Of those horses affected, 65% showed ...
