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 ...
RECENT developments in tonography and applanation tonometry have caused greater attention to be focused on the relation of the elastic properties of the coats of the eye and of ocular rigidity to the intra-ocular pressure. It is now fairly well established that the coefficient of ocular rigidity, K, is not a constant, as Friedenwald (1937) had suggested, but that it varies with the intra-ocular...
Primary open angle glaucoma (POAG) is a multifactorial disease characterized by progressive retinal ganglion cell death and visual field loss. It is known that alterations in intraocular pressure (IOP), blood pressure (BP), and ocular perfusion pressure (OPP) can play a significant role in the pathogenesis of the disease. Impaired autoregulatory capacity of ocular blood vessels may render tissu...
AIM To provide a new tool for the evaluation of altered ocular surfaces by using a combination of impression cytology, laser scanning confocal microscopy and advanced image analysis. METHODS The expression of keratin 3 (K3), keratin 12 (K12), keratin 19 (K19) and mucin 1 (MUC1) was analysed by immunofluorescence on both histological sections of nine corneoscleral buttons from normal donors co...
The aim of this study is to investigate in vivo and ex vivo ocular surface alterations induced by dry eye disease and modification after osmoprotective therapy. Forty-eight eyes of 24 patients suffering from dry eye have been recruited. All patients received Optive (compatible solutes) eye drops in one randomly selected eye and Hylogel (sodium hyaluronate 0,2%) in the other. Follow-up included ...
<b>Background:</b> Uveitis is one of the most frequent ophthalmologic manifestations in rheumatology. Uveal inflammation can underlie a systemic inflammatory rheumatic disease (SIRD) approximately 30% cases with significant burden on quality life since it represents cause blindness up to 20% Western countries. <b>Methods:</b> In this review, we provide comprehensive over...
Background & Objective: With respect to increasing prevalence of diabetes, the chance for incidence of ocular complications among diabetics, this study was conducted to investigate the prevalence and risk factors for the incidence of the ocular complications in the patients referred to the Nader Kazemi Shiraz Diabetic center from 1998 to 2010.Materials & Methods: In a cross sectional study , su...
Components of the ocular surface synergistically contribute to maintaining and protecting a smooth refractive layer to facilitate the optimal transmission of light. At the air-water interface, the tear film lipid layer (TFLL), a mixture of lipids and proteins, plays a key role in tear surface tension and is important for the physiological hydration of the ocular surface and for ocular homeostas...
Ocular marginal zone lymphoma is a common type of low-grade B-cell lymphoma. To investigate the genomic changes that occur in ocular marginal zone lymphoma, we analyzed 10 cases of ocular marginal zone lymphoma using whole-genome and RNA sequencing and an additional 38 cases using targeted sequencing. Major genetic alterations affecting genes involved in nuclear factor (NF)-κB pathway activatio...
Purpose. The aim of this study was to investigate the relationships between MGL and ocular symptoms, several systemic conditions, and key markers of ocular surface health. Methods. We included into the study 91 healthy volunteers between the ages of 20 and 77 years. We analyzed meibomian gland morphology, function, and lid margin alterations. We correlated our findings with self-reported ocular...
