Pupil deformation

Introduction Pupil deformation refers to abnormal morphology of the pupil, or abnormal response of the pupils on both sides. Normally round, both sides are equal, and the responses of the pupils on both sides are synchronized. It can be oval in glaucoma or intraocular tumors; when the iris is stuck, there are many factors that cause irregular pupil size changes, such as age, light brightness, iris inflammation, glaucoma, intracranial lesions, poisoning, and drug effects. Some young people now like to wear colored contact lenses because they can enlarge the pupils and make them look more spiritual. However, their permeability is often poor, which is not conducive to the health of the eyes. If there is no special need, wear as little as possible.

There are many factors that cause changes in pupil size, such as age, brightness of light, iris inflammation, glaucoma, intracranial lesions, poisoning, and drug effects.

Diagnosis can be performed by using an ophthalmologic CT or MRI examination.

Differential diagnosis

Differential diagnosis of pupillary deformation:

The pupil size is not equal: the pupils on both sides are not equal and vary. The diameters of the pupils on both sides are not equal to 'pupils are not equal', except for a few cases which may be physiological variations or due to uneven illumination of both eyes, which are pathological.

Pupil fixation: poisoned eye symptoms, dilated pupils, fixed.

Asymmetry of the pupil: coma or poor eye habit.

Diagnosis can be performed by using an ophthalmologic CT or MRI examination.
