“…We agree with Holsmstrom and Larsson's suggestion, concluded from the Swedish population-based study, that prematurely born children not only treated or with previous ROP, but also those without ROP history in the neonatal period, should be followed up further (11,13,15). The results of our present study showed that ROP outcome and prematurity per se remain risk factors for visual impairment to prematurely born children at preschool age.…”

“…In accordance with Larsson (11,13,15) and Fledelius (7), in our study we found the prevalence of significant and high anisometropia in the prematurely born children than in full-term children. Within the preterm group, ROP treated children (group I) had the highest frequency of anisometropia, as noted by other researches (40,34).…”

“…In the multiple regression analysis of the Swedish study (11,13,15), they showed that astigmatism had a negative effect on good VA. According to Fledelius (7) in his study he concluded that children with high and moderate myopia had a reduced VA, but a spherical equivalent was not a significant risk factor in the multiple regression analysis.…”

“…Few studies have shown that children born prematurely have an increased risk of visual impairment, higher incidences of low vision, strabismus, visual field defects and contrast sensitivity (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). Those studies have shown outcome and development of the visual functions of children at different ages.…”

Background. Preterm birth is a very relevant problem. Retinopathy of prematurity in its severe forms causes visual impairment or can lead to blindness. The aim of the present study was to describe the visual outcome in prematurely born and full-term children at the preschool age and to evaluate the effects of prematurity per se, ROP, and treatment on visual acuity and refractive errors.Materials and methods. A prospective study on the incidence of ROP during 2006-2008 included 103 preterm infants. 81 had ROP and 22 had no history of ROP; 40 were age-matched healthy children. All underwent a complete ophthalmic examination.Results. Significant myopia (≤ -0.50D) in prematurely born children differed from full-term ones. The ROP treated group had the highest prevalence of myopia (P < 0.001). Astigmatism (>2D) was dominant in the premature group (39%) as compared with the control group (0%) (P < 0.05). 65% had significant anisometropia and 35% had high anisometropia in the preterm group and only 5% had significant anisometropia in the full-term group (P = 0.014). Within the preterm group, the ROP treated children had the highest frequency of anisometropia and strabismus (P = 0.001). Visual acuity was significantly better in the full-term than in prematurely born children (P < 0.001). Three children (7.7%) of the premature ROP treated group were visually impaired.Conclusions. Refractive errors, astigmatism, anisometropia and strabismus were more common in prematurely born children than in those born at term, especially the ROP treated group. ROP outcome and prematurity per se remain risk factors for visual impairment to prematurely born children at preschool age.

At present, the analysis of the results of visual functions (VF) of pre mature infants, i.e., visual acuity, chromatic and contrast discrimination, visual field, stereopsis, and ocular motility, has contributed to unravel the influence of ROP and its treatment on these functions. The effects of developmental conditions during the neonatal period (ROP deve lopment, low birth weight, gestational weight and age above the ex pected for ROP development, presence of neonatal complications, and brain damage) on visual functions have not yet been elucidated (1116) . ABSTRACTPurpose: Observe whether there are differences in visual functions among pre mature infants with treated retinopathy of prematurity (ROP) in relation to preterm infants with ROP and spontaneous regression; and among these two groups with ROP and the control group without ROP. Methods: Crosssectional observational no blind study. Premature infants were born between 06/199206/2006 and were exam between 06/200912/2010; re gistered in data of Hospital de Olhos Sandalla Amin Ghanem; with gestational age less than or equal to 32 weeks and 1,599 g born weigh; without ROP and ROP stages II or III, in one of the eyes, with spontaneous regression or with treatment; at least three visits during the se lection period at maximum 6 months in the first exam and minimum 4 years of age in reassessment (chronological age) were in clude. Premature that did not respond or were not located for reassessment and those that did not have conditions to do the exams were exclude. Study's groups: G1 ROP posttreatment; G2ROP postspontaneous regression; G3 without ROP (control). Visual function evaluated with visual acuity (VA), contrast sensitivity test (CST), color test (CT), eye movement, stereopsis. Results: Overall, there were 24 premature infants and 48 eyes. Normal VA: 64.28% (G1), 87.5% (G2) and 100% (G3); Normal CST: 66.67% (G1), 100% (G2) and 55.56% (G3); Normal Ishihara CT: 100% (G1 and G2) and 86% (G3); Normal Farnsworth CT: 20% (G1), 75% (G2) and 50% (G3). Normal stereoacuity: 0.00% (G1); 25% (G2) and 3.5% (G3). Strabismus: 37% (G2), 0.00% (G1 and G3). The prevalent tendency for lower response in CST and CT between the premature children in group G3 and Farnsworth color test in G1 is a curious result of this work and more study is necessary about these visual functions in older premature children. Conclusion:The visual functions showed no statistically significant difference among the groups studied.
