PURPOSE This study investigated whether vergence and accommodation development in preterm infants is preprogrammed or is driven by experience. METHODS Thirty-two healthy infants, born at mean 34 weeks gestation (range, 31.2-36 weeks), were compared with 45 healthy full-term infants (mean 40.0 weeks) over a 6-month period, starting at 4 to 6 weeks postnatally. Simultaneous accommodation and convergence to a detailed target were measured using a Plusoptix PowerRefII infrared photorefractor as a… 
Typical and atypical development of ocular alignment and binocular vision in infants – the background
TLDR
The outcomes of research into the typical motor aspects of development of binocular vision in very early childhood and the development and assessment of visual acuity, stereopsis, refraction and the process of emmetropization are covered.
Bifocals reduce strabismus in children with Down syndrome: Evidence from a randomized controlled trial
TLDR
Children with Down syndrome more often have strabismus, refractive errors, accommodative lags and reduced visual acuity than typically developing children, and the effects of bifocal glasses with those of unifocal sunglasses in children with DS are compared.
2016 International Orthoptic Congress Burian Lecture: Folklore or Evidence?
TLDR
How the understanding of strabismus has been changed by the research carried out in the laboratory in Reading over the years is outlined and a new model of thinking about convergence and accommodation may help to better understand and predict responses in patients.
Application and repeatability of ocular biometric measures for gaze position calibration in children
TLDR
The results indicated that HRs obtained through ocular biometry in a binocularly normal paediatric population are consistent with previous studies in both strabismic children and adult cohorts.

TLDR
Additional visual experience of preterm infants does not influence development of visual acuity or binocular vision during the first months of life as measured from the time of conception.
Emmetropisation following preterm birth
TLDR
The early emmetropisation process differed from that of the fullterm group but neither clinical risk factors nor measures of early refractive error were predictive of refractive outcome at 4 years.

Background: 214 orthoptists’ infants have been followed for up to 15 years, relating neonatal misalignment (NMs) behaviour to onset of convergence and 20 Δ base out prism response, and also to later

TLDR
The level of cycloplegic refractive error was the best single factor for predicting emmetropization by 18 months of age, with smaller contributions from visual acuity and Mohindra retinoscopy.
Visual-evoked response binocular summation in normal and strabismic infants. Defining the critical period.
TLDR
It is proposed that the VERBS function reflects the human critical period for the development of binocular vision and data from both infant developmental studies and adult studies were clarified.
Human infants' accommodation responses to dynamic stimuli.
TLDR
The data indicate that by the third postnatal month infants are able to respond with latencies within a factor of two of adults' and that there is little immaturity in the motor capabilities of the accommodative system compared with the sensory visual system at the same age.

Emmetropisation and accommodation in hypermetropic children before they show signs of squint--a preliminary analysis.
TLDR
It is suggested that there was a basic defect in the function, and/or the development, of the visual systems relating to both fixing and non-fixing eyes of children who had squint or microtropia; and that this defect was present before squints or micro Tropia were diagnosed.
The development of eye alignment, convergence, and sensory binocularity in young infants.
TLDR
The relatively sudden onset of binocularity, both sensory and sensory, at about 3 months of age and the high correlation between these measures indicate a common causal mechanism that probably involves refinements in striate cortex circuitry.
