Observe the pupil size and shape at rest, looking for anisocoria (one pupil larger than the other) Observe the direct response (constriction of the illuminated pupil) Observe the consensual response (constriction of the opposite pupil) Repeat with the opposite pupil; Check for accommodation (constriction of pupil when viewing a close object

There is one optical condition that can result in keyhole-shaped or cat-like pupils from birth. These changes in appearance are attributed to coloboma, which can affect the lens, iris, retina, or optic nerve. The eye disorder can also affect the eyelids, but is more common in the eye itself Scar tissue can cause the iris to stick to the underlying lens or the cornea, making the pupil irregular in shape and the iris sluggish in its reaction to light

1 Abnormalities of Pupil Structur

  1. Dyscoria is abnormal shape of the pupil, and corectopia is abnormal position of the pupil. They can occur together or independently as congenital or acquired anomalies
  2. Most often presenting as a keyhole-shaped pupil, coloboma may affect one or both eyes. Persons with this problem of the iris often have fairly good vision, but those with it involving the retina may have vision loss in specific parts of the visual field, which can cause problems with reading, writing, and close-up work or play
  3. Starburst/Jagged Pupils This is a very common condition in the eyes of double merles. The pupil will be shaped with spiked, jagged, or irregular edges. This does not allow the pupil to react normally to light and can cause a light sensitivity for the dog

A pupil that is oval in shape.

Irregularly shaped pupils suggest previous ophthalmic surgery or syphilis. A unilateral Argyll Robertson pupil (small, irregular pupil that constricts with accommodation but does not react to light) can be seen in severe vitamin D deficiency. Teardrop pupils are usually a postsurgical or neurologic finding Violation of the shape and position of one or both pupils Imbalances (oval or other deformities) are usually the result of eye disease and are observed when: A congenital ectopic pupil, when the deformation is directed mainly up and out, is often accompanied by a lens dislocation and other eye anomalie Maury, age 52, has throbbing pain in the left eye, an irregular pupil shape, marked photophobia, and redness around the iris.

I would think that could translate to the brainstem or transmission of the cranial nerve impulse to the brain. The tone of the pupils could be compromised from a interruption in neuro transmissions, resulting in a change in pupil shape, rxn to light, etc

Iris abnormalities are usually detected by an abnormal appearance. These include changes in shape or size of the pupil, iris color, or lesions on the iris. Some iris disorders affect vision, but many do not. The latter are first noted by families or physicians (during a penlight examination or by noting an abnormality of the red reflex) Most, if not all, ophthalmologists strive to achieve a round pupil after cataract surgery with posterior chamber lens implantation. The presence of pupil abnormalities and iris modifications is cosmetically undesirable and may affect the quality of postoperative vision. The pupillary motility may be A serious, penetrating eye injury can damage your iris and cause the pupil to become dilated and irregular in shape. Sometimes, this sort of injury can occur during an eye surgery, such as a complicated cataract surgery or a corneal transplant

Pupils, or the black parts at the center of the eyes, change size to regulate the amount of light entering the eye. Pupils are large in the dark to let more light in and small in bright light The pupil shape becomes irregular from the swelling of the iris. Other signs and symptoms include blurred vision, sensitivity to light, and pain. Unlike conjunctivitis, in which the redness is prominent at the periphery, the redness is more around the iris in the case of iritis Argyll Robertson (AR) pupils, are characterized by small and irregular pupils that have little to no constriction to light but constricts briskly to near targets (light-near dissociation). The affected pupils initially appear small, and are irregular, but as opposed to the tonic pupil do not maintain increased tone to near targets. The pupils are noticeably able to accommodate to near targets. Abnormal pupils Anisocoria: Anisocoria means unequal pupils. If there is a poor reaction to light in one eye and the anisocoria is more evident in a well lit room, then the affected pupil is abnormally large. If there is a good reaction to light in both eyes but a poor dilation in the dark then the affected pupil is abnormally small The pupils are irregular in shape and very miotic. The near reflex is normal (light-near dissociation).
