Unilateral cryptophthalmia.

Two patients had the variable clinical features of unilateral cryptophthalmia. A 5-month-old boy had isolated unilateral cryptophthalmia: a small boney orbit, deformed optic canal, and a small amorphous mass with no normal intraocular tissue representing the globe. No extraocular muscles or optic nerve were identified by B-scan ultrasound or by computed axial tomography x-ray techniques. The second patient, a 13-year-old girl, had unilateral cryptophthalmia, and numerous systemic abnormalities including a head circumference less than the third percentile, severe mental retardation, hypoplasia of the left side of the head, and a left facial cleft deformity. She also had contractures of hips, knees and ankles, and bilateral spasticity and jerky movements. The left boney orbit was contracted and deformed and contained a small amorphous tissue with no ocular detail, as revealed by B-scan and computed tomography scan.

Premature cataracts associated with generalized lentigo.

Generalized lentigo (leopard syndrome) is an autosomal dominant trait characterized by lentigo, sensorineural deafness, retarded growth (below 25%), ocular hypertelorism, mandibular prognathism, pectus carinatum or excavatum, dorsal kyphosis, winging of the scapulae, valvular pulmonary artery stenosis, electrocardiographic conduction defects, and genitourinary defects. Ocular evaluations of patients with generalized lentigo have revealed the appearance of multiple small white punctate and comma-shaped opacities in the cortex and nuclci of the lenses of affected patients. On the basis of age of the patients examined, it would seem that the corneal opacities first appear in the third decade. Although the opacities may be extensive, the lens opacities do not appear to impair visual function until approximately twenty years after they first appear.
