The LEA Grating Test in assessing detection grating acuity in normal infants less than 4 months of age.

Purpose: To assess binocular detection grating acuity using the LEA GRATINGS test to establish age-related norms in healthy infants during their first 3 months of life.

Method: In this prospective, longitudinal study of healthy infants with clear red reflex at birth, responses to gratings were measured at 1, 2, and 3 months of age using LEA gratings at a distance of 28 cm. The results were recorded as detection grating acuity values, which were arranged in frequency tables and converted to a one-octave scale for statistical analysis.

[Visual behavior and socioeconomic and demographic profile of the premature newborns from Federal University of Pernambuco Maternity (UFPE)].

Objective: To characterize the behavior of premature newborns in the first year of chronological age.

Methods: This is a cross-sectional descriptive study, bound to a longitudinal study titled: "Comparison of visual behavior on the first quarter of year of life of premature nursling born at two maternities of Recife/PE." The sample was composed by 52 premature newborns selected from June, 2007 to June, 2008 from the Maternity of the Federal University of Pernambuco (UFPE).

Visual function and fine-motor control in small-for-gestational age infants.

Objective: To compare visual function and fine-motor control of full-term infants small-for-gestational age (SGA) and appropriate for gestational age (AGA), in the first three months.

Method: We evaluated prospectively 31 infants in the 1st month; 33 in the 2nd and 34 infants in the 3rd month, categorized as full-term; birth weight less than 10th percentile for SGA and 25th to 90th percentile for the AGA group. Genetic syndromes, infections, multiple congenital malformations were excluded.

[A method to evaluate visual ability in infants].

The purpose of this study is to introduce a method to evaluate visual functions in infants in the first three months of life. An adaptation of the Guide for the Assessment of Visual Ability in Infants (Gagliardo, 1997) was used. The instrument was a ring with string.

[Observation of language, visual and hearing function development in infants].

Objective: To investigate language, visual and hearing function development among infants in a day-care center based on educators' assessments.

Methods: One hundred and fifteen infants who attended a day-care center at one university of the São Paulo State, Brazil, were assessed during the period between 1998 and 2001. The "Protocol for Observation of Language, Visual and Hearing Function Development," containing a total of 39 standardized tests, was utilized to assess infants from three to twelve months old.
