INTRODUCTION Unilateral mydriasis is a seriously significant finding in neurologic examinations indicating life-threatening conditions such as cerebral vascular injuries. CASE PRESENTATION A 24 year old woman with mandibular trauma was referred to our center after five days for a reduction of the right mandibular angle fracture. The patient had no history of any loss of consciousness after th...

Congenital mydriasis is defined as congenital absence of iris sphincter muscle which occurs rarely and shows autosomal dominant inheritance (1-4). It was described by White and Fulton (2) in 1937 for the first time. Fixed and dilated pupil is present from the time of birth, observed more frequently in girls and typically bilateral (1-4). Iris sphincter traumas, pharmacological dilatation and ac...

OBJECTIVE To assess the frequency and severity of ophthalmic injuries in patients with orbito-zygomatic fractures. STUDY DESIGN A case series. PLACE AND DURATION OF STUDY Oral and Maxillofacial Department, KEMU/Mayo Hospital Lahore, from January 2009 to December 2011. METHODOLOGY Patients with orbito-zygomatic fractures were divided into three groups. Group-1 patients had fracture of floo...

Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed t...

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...
