Absence of the superior rectus muscle in Apert's syndrome.

A patient with classical Apert's syndrome is discussed along with the finding of absent superior rectus muscle. This anomaly may be more common than thought, especially in relation to craniofacial anomalies. A review of Apert's syndrome and superior rectus agenesis is presented.

Anterior segment anomalies associated with the fetal alcohol syndrome.

Anterior segment anomalies were noted in eight children diagnosed as having the fetal alcohol syndrome. Peters' and Axenfeld's anomalies were among the specific defects noted. Four children have maintained clear corneal grafts. A teratogenic action of alcohol during a critical period of development of anterior chamber structures is suggested as an etiologic factor. It is proposed that the varied types and severity of abnormalities noted might result from differences in blood alcohol levels, timing of the insult, and genetic background of the fetus. The observation of various types of malformations thought to share a similar pathogenesis lends additional support to the assumption that there is an interrelationship among these types of congenital segment pathology.

Unusual variant of familial aniridia.

A woman and her two children had apparent dominantly inherited ocular abnormalities including aniridia, ptosis, nystagmus, corneal pannus, persistent pupillary membrane, lenticular opacities, and foveal hypoplasia. A broad spectrum of iris abnormalities was observed: the daughter had aniridia with persistent pupillary membrane strands traversing the anterior lens capsule; the iris of the mother and son had a velvety surface with no detailed crypts, but did have some persistent pupillary membrane tags extending from the collarette. All three family members had moderately severe bilateral ptosis, pendular nystagmus, corneal pannus, and visual acuity of 20/200. Several systemic abnormalities also were noted, including obesity and mental retardation in the two children, and alopecia, cardiac abnormalities, and frequent spontaneous abortion in the mother. Family history indicated that the children's maternal grandmother also had similar ocular findings. We believe that this constellation of findings represents a rare, apparently dominant, variant of aniridia.

Progressive hemifacial atrophy (Parry-Romberg disease).

Hemifacial atrophy (Parry-Romberg syndrome) is characterized by slowly progressive atrophy of one side of the face, primarily involving the subcutaneous tissue and fat. The onset is usually in the first two decades. Ophthalmic involvement is common; the most frequent abnormality is progressive endophthalmos with subsequent changes in the palpebral fissure. Pupillary disturbances, heterochromia, uveitis, and restrictive strabismus have also been frequently reported. We describe six cases that manifest a wide spectrum of ocular and systemic findings. They are noteworthy in that all exhibit pigmentary disturbances of the ocular fundus, a finding rarely reported. Another unusual ocular manifestation in one patient was an acquired partial third nerve palsy on the unaffected side.

Möbius and Möbius-like syndromes (TTV-OFM, OMLH).

There exists a spectrum of syndromes characterized by cranial nerve palsies, limb anomalies, and craniofacial malformations. Criteria based on type and severity of limb anomaly or presence or absence of cranial nerve palsy may alter the syndrome nomenclature due to a selection bias but do not appear to benefit syndrome delineation to any extent. Patients with seventh nerve palsy and abduction weakness are usually diagnosed as having Möbius syndrome by ophthalmologists. The observed ocular motility findings range from primarily abduction deficiencies to patients who have a Duane or gaze palsy pattern of horizontal movements. Some cases previously described as "sixth nerve and partial third" may better fall into one of the latter groups, since an isolated adduction deficit as a manifestation of third nerve involvement is rare. The presence of clinical appearance of Duane syndrome in these Möbius-type patients raises the possibility of abnormal innervation of the lateral rectus as an explanation of some patterns of motility observed.

Necrotizing scleritis following strabismus surgery for thyroid ophthalmopathy.

Necrotizing scleritis with inflammation of the right eye developed after bilateral eye muscle surgery for thyroid ophthalmopathy. Debilitating pain, delay in onset, and involvement of the sclera distinguish this condition from anterior segment ischemia. The surgery may have acted as a nonspecific trigger in an eye at risk for scleritis. Necrotizing scleritis has occurred infrequently after other types of eye surgery but, to our knowledge, has not been previously reported as a complication of eye muscle surgery.

Ocular motility in thalidomide embryopathy.

Twenty-one individuals, aged 28 to 29 years, with documented thalidomide embryopathy were examined in Sweden. The most noteworthy ophthalmologic finding was the high prevalence of incomitant horizontal strabismus, primarily of the Duane syndrome type. Less frequently seen were cases of both marked abduction and adduction limitation similar to a gaze paresis with no observable fissure changes, as well as a few cases of isolated abduction weakness or inferior oblique under-action. There were many examples of aberrant lacrimation, facial nerve palsy, and ear anomalies combined with horizontal incomitant forms of strabismus. Ear and facial nerve palsies are known to occur with ingestion of thalidomide early in the sensitive period (approximately days 21 to 26 after conception).
