Diabetic retinopathy (DR) is a leading cause of blindness among working-age adults. Early diagnosis through effective screening programs is likely to improve vision outcomes. The ETDRS seven-standard-field 35-mm stereoscopic color retinal imaging (ETDRS) of the dilated eye is elaborate and requires mydriasis, and is unsuitable for screening. We evaluated an image analysis application for the au...

791 pression of the optic nerve has also been recommend­ ed, but it should be performed within 24 hours and its effectiveness is not clear [3]. Papillary mydriasis occurring during the treatment of blow out fracture might indicate irreversible blindness, because it means that the ciliary ganglion or short ciliary nerves are injured [4]. The ciliary ganglion is located posterolateral to the glob...

An 8-year-old female Japanese Spitz dog was reffered to Shiraz University Veterinary Clinic, with signof anisocoria. Clinical examinations revealed mydriasis in the right eye. Ocular examination revealed adilated and unresponsive right pupil to focal illumination. By testing with topical 2% pilocarpine, thetentative diagnosis was parasympathetic denervation of the right iris sphincter muscle—pu...

With isolated binocular targets, the best depth discrimination is found in the fixation plane (Blakemore, C., Journal of Physiology 211 (1970) 599). More recent studies have suggested that stereoscopic thresholds are not always a simple function of absolute disparity, but depend on the relative disparities in the stimulus. Here, we explored the effects of relative disparity in more detail, taki...

Twenty eight rabbits were trained to discriminate striated patterns of different orientation, first binocularly, than with each eye separately. There was no evidence of systematic dominance of either the left or the right hemisphere.

T pupil (TP) characterized by unilateral or bilateral dilatation of the pupil and lack of light reaction due to postganglionic injury of the parasympathetic oculomotor nerve was firstly described in 1931.1 While sphincter pupillae denervation produces mydriasis, ciliary muscle denervation causes accommodation impairment. It is often accompanied with peripheral nerve dysfunctions.2 It is predomi...
