Brain pathology, eye movement disorders, and basic science of ocular movement.

Diagnosis of eye movement disorders is an important step in evaluation of patients with developmental or acquired brain lesions. A better understanding of the various pathologies requires both a detailed clinical examination and the analysis of eye movement recordings (nystagmus of various types, saccade, and pursuit anomalies). Basic science studies help to interpret these eye movement disorders.

Nystagmus.

Electronystagmographic studies with an attempt to quantify various parameters of congenital nystagmus are interesting although not conclusive clinically. This is due to the spontaneous variability of congenital nystagmus. A qualitative study (position and velocity) may be sufficient for clinical examination and treatment of congenital nystagmus. The quantification of the optokinetic response is also clinically difficult. This comes from the fact that various factors can affect the response; even healthy patients can have variable gain. However the optokinetic test, which compares the response to a nasotemporal and temporonasal stimulation, is useful. It enables us to identify patients who never had a visual binocular experience in their first year of life and who keep a directional asymmetry of the monocular optokinetic response.

[Dissociated vertical divergence. Early strabismus. Nystagmus].

The presence of a DVD makes the ocular motility examination complicate but it is a valuable sign for the clinician as it is noticed essentially in infantile early onset strabismus with latent nystagmus. It is fundamental not to confuse it with an hyperaction of the inferior oblique. It requires a surgical treatment: a recession of superior recti.

[Experience in the early detection of strabismus in child day care centers. Value in the prevention of amblyopia in young children].

A screening for early detection of strabismus in infants and young children attending day care centers in the town of Lyons was conducted during one year (1986): 838 children (3 month to 3 year old) were screened. A defective vision was found in 17 children (2%). Such early screening of strabismus, easy to realize and well accepted by the parents, is of great interest since it allows early detection and treatment with a maximum chance of complete recovery before starting primary school.

[Prevention and treatment of amblyopia in children under two years of age (author's transl)].

Numerous observations in children under two years of age tend to demonstrate that the functional amblyopia of esotropia is not congenital in origin, but develops progressively between the ages of 3 months and 2 years. The initial motor disorder is an abduction deficiency. When this is symmetrical there is no amblyopia, but there is a greater risk for the deviated eye to become amblyopic when the deficiency is, or becomes, asymmetrical. Preventive treatment of the amblyopia involves the wearing of symmetrical nasal sectors, with associated partial occlusion in established cases, duration of which depends upon the child's age. Marked amblyopia with nasal fixation requires the use of a nasal sector placed in front of the amblyopic eye (associated with occlusion of the normal eye).
