Acorea is a rare ophthalmological condition defined as the . Deriving from the Greek "a-" (without) and "kore" (pupil), this condition means light cannot pass properly through the iris to the retina.
This form occurs as a birth defect due to disruptions during embryogenesis. During fetal development, the mesodermal tissue of the iris is supposed to regress to form the pupillary opening. If this regression fails, a persistent pupillary membrane or thick fibrous tissue seals the center of the iris. While many cases are idiopathic or sporadic, others show a hereditary pattern. Recent genetic research has linked familial acorea-microphthalmia-cataract syndrome to mutations in the GJA8 gene, which encodes gap junction proteins critical for lens and eye development.

Furthermore, the lack of a pupil disrupts the flow of aqueous humor from the posterior chamber to the anterior chamber of the eye. This fluid blockage often provokes pupillary block and secondary angle-closure glaucoma, leading to dangerously high intraocular pressure that can destroy the optic nerve.

The most immediate consequence of acorea is severe light deprivation. Because the eye cannot receive adequate visual stimuli, the brain fails to develop the neurological pathways necessary for clear sight. This invariably leads to dense stimulus-deprivation amblyopia (lazy eye).
