“…In these cases there is also evidence of alterations in the development of the anterior segment: microcornea, corneal curvature and lens increase 16,19 . The fact that preterm children with retinopathy present a greater disposition to myopia-like refractive errors [3][4][5][6][7][8] was again confirmed in this study and, considering the degree of myopia according to the performed treatment, we deem that the risk for severe myopia is higher in those patients who received cryotherapy than in those treated with lasertherapy, similarly to the data found in the world literature 6,15,19 .…”

Retinopathy of prematurity: refractive errors in patients treated with cryotherapy or laserPurpose: To examine the spherical equivalent of refractive errors in preterm children with threshold retinopathy of prematurity treated with cryotherapy or laser.Patients and Method: A group of 14 one-year-old children (selected from 761 preterm children born at the Hospital São Paulo of the Universidade Federal de São Paulo between 1988 and 1998) with stage 3 threshold retinopathy of prematurity treated with cryotherapy or laser photocoagulation was enrolled in the study and the spherical equivalent under cycloplegia was analyzed. Statistical analysis of the results was performed using Wilcoxon and Mann-Whitney tests.Results: 64.3% of the patients developed myopia. Of the patients who were treated with cryotherapy 80% showed high myopia and 20% low hyperopia. The mean of the spherical equivalent was -3.10 D in the right and -3.25 D in the left eye. There was no statistically significant difference between the two eyes regarding the refractive outcome. Concerning patients treated with laser, 55.6% showed myopia of which 20% was high myopia and 80% low myopia; 11.1% showed no refractive error and 33.3% developed low hyperopia. The mean of the spherical equivalent was -0.58 D in the right eye and -0.83 D in the left eye. A statistically significant diference was found between the two eyes. The correlation of refractive results in both groups of patients showed an increase in the amount of high degree myopia in patients treated with cryotherapy (P<0.05).Conclusions: Myopia is a frequent finding in children treated for retinopathy of prematurity. Myopia not only is more frequent but it appears with higher degrees in children treated with cryotherapy as compared with those treated with laser. Retinopatia INTRODUCTIONRetinopathy of prematurity is a vascular disease related to retinal blood vessel formation affecting preterm newborns and its severity presents an inversely proportional relation to gestational age and weight at birth 1, 2 .At present, advances in neonatology allow survival of children with extremely low gestational age and weight at birth, leading to an increase in the number of patients with ocular alteration 3 , especially retinopathy of prematurity. -ARQ.

“…Similarly, preterm infants in later years had poorer stereo acuity (Dowdeswell et al 1995), and a higher incidence of colour vision deficits (Dowdeswell et al 1995), ocular disorders (Gallo andLennerstrand 1991, McGinnity andHalliday 1993), and refractive errors (Gallo and Lennerstrand 1991). Taken together with the present findings, this suggests that at-risk infants are more likely to have some permanent visual deficits and/or show a delay in visual development that persists until adolescence.…”

Eye research in infants who experience significant perinatal complications has been restricted to evaluation of structural ocular disease and spatial vision, and results show that these aspects of vision are at increased risk for abnormal or delayed development. To expand upon previous work, a battery of 17 vision tests was employed to assess, comprehensively, longterm outcome of functional vision. Seventy-six children (38 males, 38 females), between the corrected ages of 2 years 11 months and 10 years 2 months (mean 6y 6mo) with various significant complications (e.g. very preterm birth, bronchopulmonary dysplasia, intraventricular hemorrhage) were compared to normally developing, age-matched control children (n=61; mean age 7y 1mo) on measures of visual acuity, contrast sensitivity, stereoacuity, peripheral vision, color vision, astigmatism, and binocular alignment. Results showed that at-risk children had more test results that fell within the suspect or abnormal range. At-risk children also had a slightly higher incidence of ocular disorders (e.g. strabismus) and refractive error. These data imply that children who experienced significant perinatal risk factors are at risk for long-term deficits of functional vision. However, most of these deficits appear to be relatively mild.

“…9,16,21,22,24,[27][28][29][30][31][32] O'Connor et al 16 have shown that at 10 to 12 years of age premature infants with no or regressed mild ROP had similar corrected VA than a control group of children born at term. On the other hand, severe ROP stages are well known to reduce vision.…”
