Cryptophthalmos
Cryptophthalmos is a rare condition resulting from failed differentiation of eyelid structures. There is partial or complete absence of the palpebral fissure, as the skin extends uninterrupted from the forehead to the cheek, covering the eye (Fig 17-3). The adnexa are partially developed and fused to the anterior segment; the cornea is usually malformed.
Fraser syndrome, an autosomal recessive disorder characterized by partial syndactyly and genitourinary anomalies, may include unilateral or bilateral cryptophthalmos and other ocular malformations.
