A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. PVCs do not usually pose any danger. [1]
In PCV, sudden blurring of vision or a scotoma in the central field of vision may occur in one or both eyes. [2] Another symptom is metamorphopsia. [1] Signs include polypoidal lesions, orange-red lesions in fundus, subretinal fluid, retinal detachment, subretinal hemorrhages, subretinal fibrinous material, hard exudates and drusen. [1]
From 6-12 months, children are screened at their well-child visits with the red reflex test, assessment of eye movement, and proper pupil dilation. From 1 year to 3 years of age, children often undergo a "photoscreening" test where a camera takes pictures of the child's eyes to assess for developmental abnormalities that may lead to amblyopia ...
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...

The general cause of polycoria is unknown, but there are some other eye conditions that are in association with polycoria. These include (although not often) polar cataracts, glaucoma, abnormally long eyelashes, abnormal eye development, and poor vision. [citation needed] There have been cases diagnosed from age 3 to adulthood.
Microphthalmia (Greek: μικρός, mikros, 'small', ὀφθαλμός, ophthalmos, 'eye'), also referred as microphthalmos, is a developmental disorder of the eye in which one (unilateral microphthalmia) or both (bilateral microphthalmia) eyes are abnormally small and have anatomic malformations.
