The clinical and pathological features of an early-onset autosomal dominant photoreceptor degeneration in the Abyssinian cat are described. Ophthalmoscopic evidence of retinal disease at 8-12 weeks of age was always preceded by marked dilatation of the pupils, impairment of the pupillary light reflex, and nystagmus. The electroretinogram was unrecordable in all but one of the affected individuals examined. Abnormal photoreceptor development was observed by both light and electron microscopy in retinas of a 22-day-old kitten; in this individual, no outer segment material was detected, and inner segments showed impaired development which was more severe towards the posterior pole. In a 40-day-old kitten, the inner segments were relatively well-formed, whereas the outer segments, though present, showed marked disorganization and degenerative change. The retinas of older individuals showed more advanced photoreceptor degeneration, with thinning of the neural retina. This early-onset retinopathy, which may be classified as a rod-cone dysplasia, is distinct from the hereditary retinal dystrophy (progressive retinal atrophy) previously described in this breed. The gene symbol Rdy has been adopted.

A patient with absence of the septum pellucidum, optic hypoplasia, congenital nystagmus, hemiatrophy, and seizures fulfilled clinical and radiological criteria for diagnosis of both septo-optic dysplasia and the syndrome of absent septum pellucidum with porencephalies. The anatomical and clinical similarities between these two syndromes suggest a common embryological basis. Their simultaneous presence in this case further supports this explanation. Clinically mild forms of both septo-optic dysplasia and the syndrome of absent septum pellucidum with porencephalies are now detected with the aid of computed tomographic scanning in patients with unexplained hemiatrophy, congenital nystagmus, seizures, and short stature.

The clinical, neuroradiologic, and endocrine features in 16 patients with septo-optic dysplasia are reviewed. All of the patients had clinical optic nerve hypoplasia with varying degrees of nystagmus and visual impairment. Only one-half of the patients had absence of the septum pellucidum. Fourteen children were growth hormone deficient, 9 were adrenocorticotrophic hormone deficient, 3 were thyroid-stimulating hormone deficient, and 4 had diabetes insipidus. In most instances, the diagnosis of septo-optic dysplasia can be established by physical examination and neuroradiologic findings, at which point a thorough evaluation of the hypothalamic-pituitary endocrine function is indicated because of the high incidence of hypopituitarism with this syndrome.

Septo-optic dysplasia was detected in a 3 month-old boy. Abnormalities consisted of agenesis of septum lucidum as shown by cerebral CT scan and of hypoplasia of optic nerves resulting in pendular nystagmus and visual impairment. A slight visual improvement was observed at 10 months of age. Growth curve was normal and blood GH determination was not performed. Rubella infection had occurred in the 2nd month of pregnancy with rising antibody titers up to the 7 1/2 month.

The eye symptoms in dysostosis craniofacialis Crouzon can be divided into obligate and facultative signs; the latter are nystagmus, megalocornea, coloboma of the iris, corectopia, ectopia of the lens and cataract. There is no causal relationship between these symptoms and the dysostosis craniofacialis. The common eye findings in this disease use proptosis, divergent strabism, hypertelorism with dystopia canthi lateralis as well as in about 80% an atrophy of the optic nerve. It is considered until now that the premature synostosis of cranial sutures is the leading and only pathogenetical factor in this disease. This theory can no longer be sustained because of its inability to explain the above mentionned eye findings. We want to stress on a malformation of the prosencephalic head organisator leading to a dyschondroplasia that mainly affects the base of the skull. This frontal dysplasia causes a characteristic displacement of the building materials and thereby produces the common eye findings in this disease.

It is reported on a nine year old boy with the oligosymptomatic form of the septo-optical dysplasia de Morsier: congenital nystagmus with nearly complete loss of visus due to a hypoplasia of the opticus-nerve of both sides, growth retardation (dwarfism) because of STH-deficiency and lack of the gonadotropins. The septum pellucidum is present. The cause of this embryologic malformation within the prosencephalon is not known.

We report on a boy with multiple epiphyseal dysplasia (MED), mild short stature, small head, mental retardation and congenital nystagmus associated with other visual problems. These manifestations were similar to those seen in Lowry-Wood syndrome (LWS). He also had hypoplasia of the corpus callosum and leukonychia totalis, which were not described in the previous cases.

We report the case of a mature newborn infant, which aroused attention 8 hours after birth due to an unexplainable paroxysmal tachypnea together with subsequently prolonged apnea. The combination of tachypnea, athetoid movement patterns, apraxia of the tongue, nystagmus and dysplasia of the cerebellum with dilation of the 4th ventricle, led to the diagnosis of Joubert-Syndrome. The child also showed a variation of a connatal unilateral facial nerve palsy, which has not previously been described in connection with a Joubert-Syndrome.

This is a report of a case of cardio-facio-cutaneous (CFC) syndrome in a three-year-old boy. Apart from obvious signs of retardation in his mental and motor development, the child was conspicuous through his short stature, relative macrocephaly, vitium cordis, pendular nystagmus and ptosis and optic atrophy on both sides. The typically dysmorphic facial features that characterize this syndrome such as high forehead, biparietal impression, downward slant of the palpebral fissures, hypoplastic supraorbital ridges, depressed nasal bridge, high palate, and dysplasia of the ears, were particularly marked in this case. The hands and feet were plump, the skin rather thick, and the hair sparse and very curly. A chromosome analysis as well as metabolism tests proved normal. Until now there have been 27 reports of such cases in medical literature.

The ophthalmologic findings associated with frontonasal dysplasia have not been defined previously in a large series of untreated children. We reviewed the ophthalmic manifestations of a series of patients with frontonasal dysplasia who were seen as part of their craniofacial evaluation. All had undergone a complete ophthalmologic examination before any manipulation of either the orbits or the soft tissues of the orbital contents. From 1986 to 1991, 23 patients with frontonasal dysplasia were seen; ophthalmologic abnormalities were found in 20 (87 percent). Abnormalities included significant refractive errors, strabismus, nystagmus, and eyelid ptosis. Three patients had amblyopia, a treatable cause of visual loss, from strabismus or anisometropia. Ten eyes in seven patients (30 percent) had severe structural anomalies, such as optic nerve hypoplasia, optic nerve colobomas, microphthalmia, cataract, corneal dermoid, or inflammatory retinopathy, that resulted in an acuity of 20/100 or worse. The high incidence of ocular abnormalities indicates that early assessment by an ophthalmologist should be part of the initial evaluation of patients with frontonasal dysplasia to detect treatable visual or ocular problems.
