Cryptophthalmos is a rare condition that presents with partial (Fig 10-13A) or complete (Fig 10-13B) absence of the eyebrow, palpebral fissure, eyelashes, and conjunctiva. The partially developed adnexa are fused to the anterior segment of the globe. Cryptophthalmos may be unilateral or bilateral. Histologically, the orbicularis oculi, levator muscle, tarsus, conjunctiva, and meibomian glands are attenuated or absent; thus, attempts at reconstruction are difficult. Severe ocular defects are present in the underlying eye, which can be microphthalmic or associated with an orbital cyst.
