In squinting patients with A.R.C. during the cover test, the keeping of fixation exhibits sometimes an hypermetric movement of the eye, which is accounted with a false localization of images.

After defining physiological fixation of the fovea and relating our knowledge of its normal development in the context of spatial perception, we have reviewed the pathological adaptations encountered in strabismus. Out of all the clinical examinations that are possible in very young children and which enable sensory disturbances to be revealed, the examination of fixation appears to be simple and dependable, sometimes well before the appreciation of the comparaison of visual acuity of the two eyes. Amblyopia can be suspected using this method in cases of poor foveal fixation when compared with the other eye, and it enables treatment to be instituted and controlled all the more efficiently since therapy in an early stage can lead to a rapid recovery and maintenance of normal development.

The vertical vergences are rather weak physiological conjugate movements of the eyes. When the ocular axes approach each other or deviate, a vertical convergence or divergence occurs. These reflex movements are evoked either by visual stimuli (fusional vergence) or by labyrinthine stimuli. In pathological situations vertical vergences may become evident in permanent or alternating hyperphorias, in the strabismus occurring in the Hertwig-Magendie syndrome, in see-saw nystagmus and in labyrinthine lesions (such as Meniere's disease, after labyrinthectomy and after section of the VIIIth nerve).

A study was made of 151 children referred to orthoptic clinics for suspected squint or suspected impairment of visual acuity. In only 50 children was there no abnormality. The contribution of different branches of the health service to detection and referral was measured. Parents and general practitioners were found to have an important role in early detection and referral, but there remained an important group of 19 children with squints undetected by their parents.There was some evidence of delay in referral, with less than half of the children with true squint being seen by a specialist within six months, and the reasons for this are discussed in terms of parents' and doctors' understanding of visual problems in children. Delay is discussed in relation to the complexity of services for child health and to recent proposals for the integration of paediatric surveillance in general practice.

The quality of visual experience during infancy determines the functional sensitivity and precision of the mature primate visual system. Infant monkeys subjected to monocular form deprivation show a period of critical visual development that, though decreasing in sensitivity, lasts throughout the first 2 years of life. Photopic threshold spectral sensitivity appears to have a briefer critical period, which is essentially complete by 6 months old, whereas scotopic visual functions appear well developed by 3 months old. Binocular visual functions seem to have the longest period of sensitivity to abnormal visual experience because periods of monocular form deprivation initiated during the first 2 years affect visual functions. Viewing the world through prisms, which mimics the condition of strabismus, causes a permanent loss of cortical binocular cells and stereopsis in monkeys. This result explains stereoblindness in children having equivalent clinical histories.

Colloid cysts typically reside within the area of the anterior third ventricle, in the proximity of the foramen of Monro. Although they are considered to commonly localize in various parts of the cerebrum, they are exceedingly rare outside the ventricular system and rarely occur within the velum interpositum. We have reported here a rare case of a velum interpositum colloid-like cyst in a 23-year-old man, who presented to our clinic with temporary binocular strabismus, which he had been experiencing for the previous year. In addition, we have briefly reviewed evidence regarding the generation, anatomy, and pathogenesis of colloid cysts, as well as the management options for such rare cases. The present report is only the third to describe a colloid-like cyst located within the velum interpositum, providing additional data that may aid in elucidating the pathogenesis of these neoplasms.
