| Resumo: | Introduction: In Brazil, despite the scarcity of population studies that demonstrate
the prevalence and causes of visual impairment, important programs for visual
screening in the pediatric population have been created with the aim of reducing
the chances of developmental delay. Objectives: This study presents a protocol
for the evaluation of different aspects of visual function of premature newborns
still hospitalized and investigates the threshold of visual acuity of premature
newborns. Material and Methods: This is a cross-sectional observational
analytical study approved by the Research Ethics Committee of the Federal
University of Rio Grande do Norte under number 1.876.007, carried out in a public
maternity hospital, located in the Northeast region of Brazil, reference in high-risk
pregnancies in the state of Rio Grande do Norte. Data collection occurred during
the period from February to October 2018 and the sample consisted of premature
newborns admitted to the Neonatal Intensive Care Unit who had a corrected
gestational age between 30 and 36 weeks and 6 days, which were clinically
stable. The visual function was evaluated by 7 tasks compiled in a single
Standard Operating Protocol and for the evaluation of Visual Acuity it was used
in the Teller cards according to the manual's rules. During the study period, 59
newborns fulfilled the inclusion criteria and 42 were recovered, 17 were excluded
for failing to reach the test due to a fall in alertness (drowsiness or crying).
Results: Among the 7 aspects of the visual function taken, all were present in the
neonatal period and the threshold of Visual Acuity of a premature newborn close
to 32 weeks of corrected gestational age is 0.32 cpg. |
