Although accommodative adaptation has been studied extensively in young adult populations, there has been little consideration of this function in children. Accordingly, we examined accommodative adaptation by comparing pre- and post-task measurements of dark accommodation (DA) in children and young adults. DA was assessed objectively before and immediately… (More)
Ocular dominance, as measured in sighting tests, involves a temporary suppression of the input from the non-dominant eye in order to avoid diplopia. Amblyopia ex anopsia may be viewed as a long term suppression of the input from one eye for the same reason. In the absence of anisometropia, paralysis of extra ocular muscles, or other factors which would tend… (More)
The purpose of this paper will be to carefully examine the effectiveness of orthoptics as a viable treatment modality for strabismus. It will be necessary to first examine the scope of this problem and the significance of functional cure. A short discussion of perceptual and psychological effects will be included. A review of pertinent literature and an… (More)
There is a relatively high incidence of visual anomalies in persons with cerebral palsy. There has been a significant amount of investigative work into what these visual problems are. This paper reviews the literature and explores new areas, not previously reported on, in population of cerebral palsied children.
Accommodation function, in a population of severely involved cerebral palsied children, is significantly lowered or absent. This observation suggests that lowered amplitudes and accommodation facility could be part of the cerebral palsy syndrome and untrainable . This paper looks at the accommodative function and the results of vision training on such a… (More)
The forced preferential looking (FPL) technique has been used clinically, to assess visual acuity in infants for the past decade. It is generally accepted that the effectiveness of the procedure extends to the upper limit of 10 months of age. The authors discuss clinical observations on the viability of FPL as an effective technique in the measurement of… (More)
Background: Children with Down syndrome (DS) are known to have a high prevalence of visual anomalies including strabismus, high refractive errors, Brushfield spots, nystagmus, keratoconus, and external pathologies such as blepharitis and conjunctivitis. These anomalies can impair children with DS from maximum functional capabilities.
