Discussion Anisocoria can imply serious underlying pathology, so accurate pupil testing and astute observation are paramount. This review discusses the differential diagnosis of a large pupil (anisocoria more obvious in the light) and a small pupil (anisocoria more obvious in the dark), and discusses the relevant afferent pupillary defect, in which there is no anisocoria but both pupils react

Direct blunt trauma to the globe may result in traumatic mydriasis or, less commonly, miosis. Traumatic mydriasis is often associated with iris sphincter tears or small tears in the ciliary muscles that can permanently alter the shape of the pupil. - Rupture of sphincter of pupil - Rupture of sphincter of pupil (disorder) Hide descriptions.

Research of Rupture Of Sphincter Of Pupil has been linked to Hemorrhage, Eye Injuries, Nonpenetrating Wounds, Cataract, Hyphema. The study of Rupture Of Sphincter Of Pupil has been mentioned in research publications which can be found using our bioinformatics tool below.

If the pupil fails to constrict following instillation of 0.125% pilocarpine, try 1% pilocarpine solution. If the pupil also fails to constrict with 1% pilocarpine, the dilation is likely due to pharmacological mydriasis, traumatic iridoplegia, sphincter ischemia or iatrogenic damage from prior intraocular surgery.

Within the first 1 or 2 weeks of its denervation, the iris sphincter will become supersensitive to cholinergic agents such as pilocarpine diluted to a concentration of 0.125% or less. Pupillary disorders usually fall into one of three major categories: (1) abnormally shaped pupils, (2) abnormal pupillary reaction to light, or (3) unequally sized pupils (anisocoria). Occasionally pupillary abnormalities are isolated findings, but in many cases they are manifestations of more serious intracranial pathology.

Parasympathetic innervation leads to pupillary constriction. A circular muscle called the sphincter pupillae accomplishes this task.

The classic “rule of the pupil” states that when aneurysms compress the oculomotor nerve, the iris sphincter will be impaired, leading to a sluggishly reactive or dilated pupil, said Dr. Vaphiades. Rupture of sphincter of pupil Convert H21.569 to ICD-9 Code The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H21.569 its ICD-9 equivalent. The postganglionic parasympathetic fibers innervate the ciliary muscle (for lens accommodation) and the pupillary sphincter muscle (for pupil constriction) in a proportion of 30:1. (This is important to understand the pathophysiology of the tonic [Adie] pupil.) Mydriasis is the dilation of the pupil, usually having a non-physiological cause, or sometimes a physiological pupillary response. Non-physiological causes of mydriasis include disease, trauma, or the use of drugs.

Definition of sphincter muscle of pupil in the Medical Dictionary by The Free Dictionary

Anisocoria in the dark (smaller pupil abnormal) Both pupils may still constrict briskly to bright light. Surgical interventions such as sphincterectomy (dissection of the sphincter), peripheral iridectomy, or vitreous prolapse in cataract surgery complicated by posterior capsule rupture, can also affect the shape of the pupil.

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.

Very small pupils (miosis) suggest narcotic use or hyperopia (farsightedness). Unilateral miosis suggests Horner's syndrome (the small pupil is the abnormal one). It creates even tension at around 300° of the supported pupil and the chances of sphincter damage and postoperatively deformed pupil may be less. After insertion in the anterior chamber, the central segment of the device is manipulated to engage the distal pupillary margin. The pupil may be abnormally small or large at birth. Microcoria describes a small pupil, typically less than 2 mm. Primary microcoria occurs as a result of dilator muscle insufficiency.
