846 children with cerebral palsy were examined and 642 were selected for a statistical study by correspondence analysis. The aim was to identify without any prior assumptions, the relationships between the aetiological factors and the clinical findings. The study was completed by conventional statistical analysis of 584 of the cases. Small birth weight and a history of abnormal pregnancies was associated with a cerebral palsy affecting both legs, and often with a squint. Resuscitation was associated with athetosis and abnormalities of posture and behaviour. If the resuscitation lasted for more than 15 minutes or there were certain problems during delivery, severe abnormalities of both arms and major speech difficulties were observed. Resuscitation for less than 15 minutes or for an unknown time or intractable vomiting during pregnancy was associated with quadraplegia. Hemiplegia was related to post natal events but the aetiology was not always known. Foeto-maternal incompatibility was associated with athetosis, deafness, severe speech problems and ophthalmoplegias.

One hundred twenty-eight patients (most less than 13 years old) with various types of cerebral palsy were examined to assess visual acuity, refractive state, oculomotor functions, sensory fusion, and ocular health. Special procedures for examining these patients are described. Vision or ocular defects were found to be present in 86% of these cerebral palsy patients. Significant refractive errors and strabismus were the most common defects, being present in 50% or more of the patients. Ocular disease was relatively uncommon.

The asymmetrical deformities in 20 children with various types of cerebral palsy are compared with 20 children without cerebral palsy who have the so-called 'squint' baby syndrome (asymmetrical deformities of plagiocephaly, unilateral bat ear, facial and thoracic asymmetry, pelvic obliquity and apparent shortening of one leg). It is suggested that the 'squint' baby syndrome and the 'windswept' child syndrome in children with cerebral palsy are stages of the same syndrome and that in both the deformities are caused by the effect of gravity on an immobile growing child, rather than spasticity or muscle imbalance. Asymmetrical deformity should therefore be amenable to physiotherapeutic intervention, rather than trying to modify maturation of the damaged brain. As the 'windswept' cerebralpalsied child can develop some of the most severe deformities seen in cerebral palsy, it is important that asymmetrical deformities should be prevented.

A group of 238 patients with cerebral palsy were identified of whom 108 could be studied through their charts. Only 20 of these patients had strabismus. Of this group, 10 received no surgical therapy. In these patients followed up to a period of four years, no evidence of significant change in the strabismic deviation was found. Patients who were treated by medical and optical means alone did not show evidence of improvement. Surgical therapy was effective in providing a cosmetically acceptable result. Surgery was performed between two and one-half and 13 years of age in eight patients, with an average age of surgery of 6.5 years. The results which we obtained are comparable to those obtained by others at an earlier age. It does not appear that the age of surgery affects the ultimate cosmetic nor functional outcome in children with cerebral palsy.

Few guidelines have been advanced for the management of brain damaged children with strabismus. Conservative therapy with lenses, prisms, occlusion, atropine and late surgery has been suggested but without specific methods or ages being advocated. The authors undertook the treatment of these children utilizing the standard principles of strabismus therapy as applied to neurologically normal children. A further consideration is a satisfactory cosmetic appearance which wins greater self, peer and parental acceptance in these handicapped children. The results of therapy of this series of patients with cerebral palsy indicates that satisfactory alignment can be achieved in the majority even in the presence of severe motor involvement and/or mental retardation. Ninety percent of those patients with treated accomodative esotropia achieved a satisfactory alignment. Those patients with non accommodative esotropia had a satisfactory alignment in 77% of the patients operated upon and those with exotropia achieved this result in 86% of the patients operated upon. Only five (2%) patients spontaneously reduced their angles to cosmetically acceptable ranges. Overcorrections occurred in 10 (11%) patients in the surgically treated nonaccommodative esotropes and 4 (3%) of these patients required further corrective surgery. Only one exotropic patient was rendered esotropic postoperatively. The average age of initial surgery in the esotropic patients was 3.9 years and 5.7 years in the exotropic patients. The older ages for surgical intervention reflects the more conservative approach to these neurologically abnormal children and allow an increased time interval for the development of a stable preoperative oculomotor alignment.

Behavioural methods were used to assess the visual development of two infants with a history of severe perinatal hypoxia. Both infants were born fullterm and showed hypoxic-ischaemic encephalopathy and subsequent cerebral palsy. Low visual acuity, small and asymmetrical visual fields, asymmetrical binocular and monocular OKN, and absent visual threat response were demonstrated initially. Ophthalmological examination revealed strabismus, but no further abnormalities. Longitudinal assessments up to the age of two years showed impressive (partial) improvements of visual functions. The mechanism for these improvements is unknown. The present study emphasizes the necessity of repeated testing of visual functions in infants with cerebral damage after perinatal hypoxia.

In the period 1980-1987 ocular examinations were performed on 185 infants with a very low birthweight (less than 1500 g) at the age of nine months corrected for the duration of pregnancy. The mean gestational age of the infants was 30 weeks, while the mean birthweight was 1160 g. The mean spherical refraction was 0.9 D (S.D. 1.3 D), the mean astigmatism was C-0.6 D (S.D. 1.0 D), while convergent strabismus was found in 10% of the patients. The purpose of the investigation was to see if there was a relation between spherical equivalent of refraction, astigmatism and strabismus on the one hand and 11 perinatal parameters and cerebral palsy diagnosed at the age of nine months on the other hand. Statistical analysis was performed with the Student t-test. No significant correlation between the findings of ocular examination and the perinatal parameters could be detected.

The long-term outcome of infantile hydrocephalus (IH) in children born at term during a period of active shunt treatment was studied in a population-based survey. The series consisted of 68 children greater than or equal to 6 years old and born in 1967-78 in the south-western Swedish health care region. The clinical follow-up included neuro-paediatric assessment, Stott's test of motor impairment, the WISC test, CT and EEG analyses. Nineteen of the 68 children (28%) had cerebral palsy, 17 (25%) minor motor dysfunction and 32 (47%) no motor dysfunction; mental retardation was present in 26 (38%), 16 with an IQ 50-70 and 10 with IQ less than 50; 42 children (62%) had normal intelligence and epilepsy was found in 15 (22%). Compared with a non-shunted IH series from the 1950s, the survival of IH children had considerably increased. Of constituents characterizing the IH syndrome from the time prior to shunting, ataxia, divergent squint and the special "Cocktail-party behaviour" had significantly decreased, all of which conditions are highly related to chronic expansion of the ventricular system. The frequencies of other impairments such as mental retardation and epilepsy were fairly similar, reflecting the present increased survival of IH children with primarily non-IH-dependent brain damage. IH children with associated brain parenchymal defects had the poorest outcome, and those without had in general a much more favourable one. Thus the single most important factor for the outcome of IH was found to be the presence or absence of associated primary brain damage or maldevelopment.

Cerebral palsy is a permanent and non-progressive brain damage due to various causes affecting a child from the intrauterine life up to the first two years of life. Its most common cause is neonatal hypoxic encephalopathy. The cerebral damage is diffuse so that it is commonly associated with epilepsy, mental retardation, dysarthria, hearing loss and oculomotor abnormalities. Strabismus is found in 50% of children with cerebral palsy. This prevalence is significantly different from the 2% incidence of oculomotor abnormalities in the pre-school age, it is noteworthy that strabismus and refractive errors respond to the classical therapeutic measures.

In 1966-70, the survival rate for very low-birthweight (VLBW) children born in a tertiary perinatal centre was 37.1 per cent but by 1980-82 it had increased to 68.3 per cent. The latter cohort had a significantly reduced prevalence of strabismus, myopia and a head circumference under the 10th percentile, but a significantly increased prevalence of cerebral palsy compared with the 1966-70 VLBW children. Survivors born in 1980-82 had a significantly increased mean Mental Development Index (MDI) on the Bayley Scales compared with the sub-group of survivors born in 1968-70 but there was also a significant improvement in mean MDI over time for a group of normal-birthweight children. No improvement of MDI scores of VLBW survivors in the 1980-82 cohort could be attributed solely to perinatal care. The two-year-old VLBW children in the 1980-82 cohort had similar rates of sensorineural impairments, disabilities and mean MDI to those who would have survived with the care available in 1966-70. It is concluded that survival of VLBW infants has improved in recent times but that neurodevelopmental outcome still lags behind that of normal-birthweight peers.
