Symmetrical partial lateral 'cryptophthalmos'. A new concept of its embryological pathogenesis

A unique case of bilateral, partial cryptophthalmos is described, with no associated systemic anomalies. There were symmetrical, well-developed palpebral apertures medially with small conjunctival sacs, and symmetrical hemicryptophthalmos laterally. A faint groove extended temporally over the fused lids on both sides. There was a distinct plane of cleavage laterally between the disorganized microphthalmic globes and overlying tissues. The surgical observations are detailed.
