There was no difference among the three groups studied in relation to the changes of the retinal layers at OCT. Considering the left eye, there was no statistically significant difference related to the thickness of the fovea between G1 and G3. At OCT there were statistically significant differences for the greatest foveal thickness between premature infants from groups G1 and G2. However these changes corresponded to the cicatricial lesions left by the ROP treatment, without visible impairment to the macular region. At BIO, there was a statistically significant difference for the presence of alterations in the retina of premature infants from group G1.
Twenty-four premature infants (48 eyes) presented the criteria required for the research, chronological age ranging from 5 to 6 years. The premature infants were divided into three groups: G1 - with ROP post-treatment G2 - with ROP post-spontaneous regression and G3 - without ROP. There were excluded premature infants who did not attend or did not have clinical conditions for the reassessment examination. There were included premature infants born between 06/1992 and 06/2006 and examined between 06/2009 and 12/2010 gestational age less than or equal to 32 weeks and birth weight less than or equal to 1,599 g with a minimum of three visits during the selection period without retinopathy of prematurity, or with the diagnosis of ROP stages II or III in at least one eye with spontaneous regression or after ROP treatment maximum of six months of chronological age for the first examination at the service minimal chronological age of four years old in the reassessment period. Compare the retinal structure of the macula and fovea among premature infants with retinopathy of prematurity (ROP) stages II and III post treatment, premature infants with ROP stages II and III with spontaneous regression and premature infants without ROP, through optical coherence tomography (OCT) and binocular indirect ophthalmoscopy (BIO) examinations.Ĭross-sectional observational and not-blinded study.
