![]() ![]() These tests include pharmacological testing (testing for an effective drug against a specific disease or condition), a complete ocular examination (a test that examines the entire eye), and video pupillography (recording and analysis of spontaneous pupil behavior in darkness). Some tests, however, are recommended by optometrists as part of an eye exam checkup. There are no specific tests or screenings that are performed to diagnose the tadpole pupil because of the briefness and randomness of the episodes. the pupil points in the same direction the hour hand on a clock would at 7 o'clock. For example, the pupil may stretch out to a 7 o'clock position, i.e. The pupil can disorient itself in different ways before it returns to its original shape. Tadpole pupil is diagnosed and characterized by the abnormality of the pupil shape. Although women generally have the tadpole pupil, men are not unaffected by this disease and some have been reported to experience the symptoms. Studies show that a majority of those experiencing tadpole pupil are younger women from an age range of 24 to 48 years old, with no apparent health problems. The episodes can occur multiple times a day for days, weeks, or months. Episodes are generally brief and less than 5 minutes, however, some episodes have been reported to last anywhere from 3 to 15 minutes. Tadpole pupil symptoms occur in episodes. Some patients who demonstrate tadpole pupil symptoms also experienced Horner’s syndrome or Adie’s tonic pupil Other symptoms may include blurred vision, abnormal periocular sensations (unusual feelings around the eyes ), migraines, and feelings of a chilled face. One part of the iris is pulled to a peak, and then returns to normal after the episode. Distortion can occur in any segment of the iris. The primary symptom is pupillary distortion (changing of the size or shape of the pupil). 4 Common eye examinations for the pupil and internal eye.Episodic segmental iris mydriasis was first described and termed “tadpole pupil” in 1912 by HS Thompson Contractions of the iris dilator muscle, a smooth muscle of the eye running radially in the iris, can cause irregular distortion of the pupil, thus making the pupil look tadpole shaped and giving this condition its name. These spasms can affect any segment, or portion, of the iris and involve the iris dilator muscle. Tadpole pupil, also known as episodic segmental iris mydriasis, is an ocular condition where the muscles of the iris begin to spasm causing the elongation, or lengthening, of parts of the iris. When the pupil takes on the shape of a tadpole, the condition is called tadpole pupil. ![]() Due to certain muscle spasms in the eye, the pupil can resemble a tadpole, which consists of a circular body, no arms or legs, and a tail. The eye is made up of the sclera, the iris, and the pupil, a black hole located at the center of the eye with the main function of allowing light to pass to the retina.
