Background
Children may present in early infancy for evaluation of decreased visual responsiveness. Most such infants have systemic or ocular abnormalities that explain their poor fixation and tracking. Some infants, however, have no other medical or ocular problems. This study evaluated prognostic factors in this latter group of otherwise normal infants with decreased visual responsiveness.
Methods
This was a retrospective cohort study in which medical records of infants evaluated for decreased visual responsiveness were reviewed to identify children who had no history of premature birth or systemic problems associated with developmental delay. Examination findings that were predicted to indicate a good prognosis included: the presence of some reaction to light, normal pupil responses, no nystagmus, and no structural ocular abnormalities. Follow-up information was obtained from office visits and telephone interviews. Main outcome measures were visual acuity and developmental status.
Results
Thirty-two children met the criteria noted above. Six were excluded due to lack of follow-up. Four were normal by the time of their initial examination. Follow-up for the remaining patients ranged from 3 months to 11 years (mean 2.94 years). One patient developed strabismus and required surgery. The remaining patients all had normal vision and development.
Conclusions
Otherwise normal infants who present for evaluation of decreased visual responsiveness have a good prognosis if they have some reaction to light, normal pupil responses, absence of nystagmus, and no structural ocular abnormalities. The developmental prognosis for these infants appears to be good. Additional testing at the time of initial evaluation is not indicated.
