**5. Conclusions**

Neurotypical developing toddlers and without visual impairment with slow gross motor development had higher exophoria and further near point of convergence values compared with fast gross motor development toddlers. No statistically significant differences were found in visual acuity and stereopsis between both slow and fast gross motor development toddlers.
