Am J Ophthalmol 1983 Oct 96(4):467-77.The abdomen is that part of the body, lying between the chest and pelvis, containing the digestive organs (i.e. Tadpole-shaped pupils caused by segmental spasm of the iris dilator muscle. Balaguer-Santamaria JA, Escofet-Soteras C, Chumbe-Soto G, Escribano-Subias J. So all patients need to be treated with respect and their complaints taken seriously, he says.ġ. ![]() But as unlikely as their symptoms sometimes seem, some are indeed real. Rappon says, patients say a lot of crazy things. Patient reassurance is the only current management. Enumerate your findings to the neurologist or neuro-ophthalmologist, as well as what tests you would like performed and/or which conditions you wish to be ruled out, he says. If you suspect one of these associated conditions but are unable to confirm them yourself, make a neurological referral, Dr. 3 Again, be sure to rule out pharmacological exposure. Also, application of 10% phenylephrine can clinically replicate tadpole-shaped pupil, he says. All are seen in a high percentage of patients who have tadpole-shaped pupil, though it is not known how or to what extent these conditions affect pupillary distortion. The associated conditions of tadpole-shaped pupil are Adies syndrome, Horners syndrome and migraine, Dr. Although this is a benign event that does not require further medical evaluation, you should perform a complete ocular examination including pupillary testing and a full-threshold visual field exam, he says. Q: Should I comanage this patient with a neurologist or neuro-ophthalmologist?Ī: The irregular pupil is caused by a focal spasm of the iris dilator muscle, probably due to neural stimulation rather than from a muscular origin, Dr. Patients experience an unusual sensation in or around the affected eye during the episode, and some report blurred vision during each event. Rappon says, these clusters of pupil distortion may recur weeks or months later. 3Īlthough tadpole-shaped pupil resolves spontaneously, Dr. It causes a distortion of the pupil that usually lasts less than two minutes and occurs several times per day, sometimes for weeks at a time. This uncommon condition is typically unilateral and mainly affects females. The next most likely condition is tadpole-shaped pupil. However, neither BEUM, Adies nor Horners syndromes cause an irregular pupil shape, Dr. 2 The median duration of this condition is 12 hours with a frequency of two to three episodes per month. 1 More commonly found in females, BEUM is very often associated with blurred vision, headache or orbital pain, and may be a limited form of an ophthalmoplegic migraine. This uncommon condition arises from what is probably a heterogeneous group of conditions that result in either para-sympathetic deficiency or sympathetic hyperactivity. The next condition to rule out is benign episodic unilateral mydriasis (BEUM), he says. So, a thorough case history is essential to rule this out. These include Adies and Horners syndromes, benign episodic unilateral mydriasis, pharmacologic misadventure and something known as tadpole-shaped pupil.Īmong these conditions, accidental exposure to a cholinergic agonist is the most commonly encountered, Dr. Is this patient imagining this, or is she truly experiencing a clinical condition?Ī: Several clinical conditions can cause intermittent anisocoria, says optometrist Joseph M. She says this happens several times a day. Q: A patient presented with a complaint that her pupil looks like a cats eye for several minutes and then returns to normal. ![]()
