The syndrome of idiopathic episodic unilateral mydriasis probably comprises a heterogeneous group of conditions that result in parasympathetic insufficiency of the iris sphincter in some patients, and sympathetic hyperactivity of the iris dilator in others. Patients with episodes similar in characte . The syndrome of idiopathic episodic unilateral. Corneal inlay implantation to treat extensive glare and photophobia in a young patient with traumatic mydriasis Mydriasis is due to stimulation of the iris dilator muscle or compromise of the parasympathetic tone of the iris sphincter muscle, or both. As with miosis, mydriasis can be pharmacologically induced with agents such as atropine. However, unlike miosis, mydriasis is associated with many conditions
The episodes of mydriasis commenced 7 years prior and disappeared after closure of the ASD but recurred a year ago. Their frequency ranges from 10 times a day to once in a few months. The patient did not have any medication, could not identify any precipitating factors, and reported no simultaneous headache, orbital pain, nausea, photophobia, ptosis, diplopia, redness of the eye, or other. Anisocoria is a condition characterized by unequal pupil sizes. It is relatively common, and causes vary from benign physiologic anisocoria to potentially life-threatening emergencies. Thus, thorough clinical evaluation is important for the appropriate diagnosis and management of the underlying cause
Multisystemic smooth muscle dysfunction syndrome (MSMDS) presents with a recognizable pattern of complications, including congenital mydriasis, patent ductus arteriosus (PDA), pulmonary artery hypertension, aortic and other arterial aneurysms, moyamoya-like cerebrovascular disease, intestinal hypoperistalsis and malrotation, and hypotonic bladder Traumatic mydriasis History or evidence of trauma Many disorders are accompanied by anisocoria due to iris or neurologic dysfunction but usually manifest with other, more bothersome symptoms (eg, uveitis , stroke , subarachnoid hemorrhage , acute angle-closure glaucoma )
Transient Miosis VossiusRing Traumatic mydriasis-temporary or permanent Sphincter radial tears Iridodialysis: Pupil is D shaped •IOP May be high due to hyphaemaor inflammation May be low due to ciliaryshut-dow Injury to the pupillary sphincter muscle can result in an isolated finding of mydriasis, a condition referred to as traumatic mydriasis or stunned iris. If the muscle is only contused, the effects will be transient, while complete tears can result in permanent mydriasis. 4 A number of potential causes of transient traumatic myopia have been proposed, such as: (1) ciliary spasm, 5 (2) anterior displacement of the lens-iris diaphragm induced by ciliary effusion, 2,6.
A 40-year-old female gardener presented with a 1-day history of a dilated left pupil (figure 1). She denied headaches, vomiting, double vision, eye pain or discharge. There was no history of topical eye-drops or trauma. On examination, her left pupil was 8 mm compared with her right pupil at 3 mm. The left pupil was non-reactive to direct and consensual light responses, and accommodation. We report the case of a 12-year-old boy who attended our outpatient clinic after accidentally being hit on the right eye by the projectile of a toy gun (l Fig. 1). The clinical examination showed a localized corneal edema, a hyphema, traumatic mydriasis, shallow anterior chamber and low intraocular pressure (IOP) of 5mmHg. Best spectacle corrected visual acuity (BSCVA) was reduced to 20/400 Traumatic mydriasis occurs in more than 10% of patients and is secondary to sphincter muscle tears or paralysis. Most commonly, miosis occurs with a severe traumatic iritis Oculomotor nerve palsy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements. Thus, damage to this nerve will result in the affected individual being unable to move their eye normally Traumatic Optic Neuropathy (TON) is a condition in which acute injury to the optic nerve from direct or indirect trauma results in vision loss. The severity of optic nerve damage may range from simple contusion to complete avulsion of the optic nerve

Withdrawal of drugs - If the cause of miosis or mydriasis is an inadvertent application of topical agents, then it can be easily cured by the withdrawl of such drugs. No required or available treatment - For idiopathic or isolated efferent mydriasis, a treatment procedure is not required We present the case of a patient who had a 3-year history of episodes of transitory unilateral mydriasis with omolateral blurred vision followed by headache. Thereafter, during the last 4 years, the patient developed a migraine with visual aura We present the case of a patient who had a 3-year history of episodes of transitory unilateral mydriasis with omolateral blurred vision followed by headache. Thereafter, during the last 4 years, the patient developed a migraine with visual aura, without further episodes of transitory mydriasis. We suggest that the transitory mydriasis previously present could be considered as an unusual form.

The pupil constricts or dilates (enlarges) according to the amount of light that enters the eyes, with both pupils normally dilating in dim light and constricting in bright light. Anisocoria is a condition in which the pupils of the cat's eyes are different sizes. Anisocoria is a sign of an underlying disease condition and therefore there are several different causes The iris is in normal shape there is no visible tears on it but the reaction to light is poor. After 20 days from trauma one time pilocarpine was used and the pupil shrinked to maximal small size (almost 1mm) but next day the pupil returned to previous mydriasis state Side of pupillary mydriasis predicts the cognitive prognosis in patients with severe traumatic brain injury.

Mydriasis excessive or persistent dilation of the pupil that is a symptom of ophthalmic or systemic conditions the ophthalmologist may induce Mydriasis using topical atropine to examine the inner eye. Two eye conditions cause Mydriasis; Glaucoma; damage to iris. Inflammation or tears in iris also lead to Mydriasis Traumatic mydriasis (dilated pupil) information. Ask Question Asked 4 years, 3 months ago. Active 3 years, 4 months ago. Viewed 344 times 1. How and when (if its possible) to say that traumatic mydriasis is going to be healed or stay forever? Is there some. Dilation, or widening, of the pupils of the eyes is normal in conditions of low light in order to allow more light to reach the retina. Medically, dilation of the pupils is known as mydriasis. Specific medications known as mydriatics are administered to dilate the pupils for ophthalmologic examination Also, I read that the surgical procedure cerclage pupilloplasty can be used to correct traumatic mydriasis. However I was alarmed to read that once the cerclage is in place, the pupil can no longer dilate reactively (my affected pupil can still change size reactively, it is just consistently too big by a millimetre or two in diameter from observation in a mirror)
Hi everyone. I have what seems to be a traumatic mydriasis from blunt trauma to my right eye that happened back in the middle of December. My history: Middle of December I took a slapshot to the eye from a rigid PVC hockey ball (wasn't wearing a cage). I immediately lost vision in my right eye Abstract. The effectiveness of 1% pilocarpine in counteracting the mydriatic effect of phenylephrine hydrochloride (Neo-Synephrine Hydrochloride), hydroxyamphetamine hydrobromide (Paredrine), tropicamide (Mydriacyl), and homatropine hydrobromide in the concentrations ordinarily used in clinical ophthalmology was studied in 15 subjects Traumatic Mydriasis, Cataract, Zonular Dialysis. Thomas A. Oetting, MS, MD. This patient had blunt trauma with zonular dialysis, traumatic mydriasis, and a mild lens opacity that was progressing.
