Purpose: We intended to investigate the clinical features and success rates of surgery in premature children with exotropia. Methods: Twenty-two exotropia children with a gestational age of less than 37 weeks, or a birth weight of less than 2,000 g were included. The children had also been clinically observed for at least six months after surgery for exotropia. This study analyzed the results of their surgery in terms of gestational age, birth weight, ages at the first examination, and surgery, visual acuity, the angle of exodeviation at the first examination and the maximum angle of exodeviation before surgery, the frequency of accompanied strabismus, and surgical results. Surgical success was defined as postoperative angle of deviation less than 10 PD. The patients were divided into success and failure groups, and a comparative analysis was performed between the 2 groups. Results: The mean maximum angle of exodeviation before surgery was 28.4 ± 8.2 PD at far distance and 28.5 ± 8.3 PD at near distance. The mean angle of exodeviation at last visit after surgery was decreased to 8.0 ± 14.2 PD at far distance and 9.1 ± 14.8 PD at near distance. The success rate of surgery was measured to be 59.1% at the last visit. Recurrence was a major cause of failure, which occurred in eight cases (36.4%). The angle of exodeviation at the first examination and the maximum angle of exodeviation in the failure group were higher than in the success group with statistical significance. The incidence of vertical strabismus before or after the surgery was 45.6% (10 cases) and there was no statistically significant difference between the 2 groups. Conclusions: The premature children with exotropia had a relatively low surgical success rate and the major cause of the surgical failure was the recurrence of exotropia. The degree of the angle of deviation at the first examination and the maximum angle of exodeviation before surgery was an influential factor on the surgical results.

Purpose: To evaluate the refractive status, anisometropia, amblyopia and strabismus in 3-year-old premature children. Methods: A total of 161 eyes from 82 premature infants were retrospectively reviewed and divided into three groups according to the presence of retinopathy of prematurity (ROP) and treatment; Group 1 (68 eyes): without ROP, Group 2-1 (32 eyes): spontaneously regressed ROP, and Group 2-2 (61 eyes): regressed ROP with treatment. The incidences and clinical features of refractive er...

. Frequency and natural history of retinopathy of prematurity (ROP) were prospectively studied in 142 preterm infants with birth weight (BW) less than 1501 g and/or gestational age (GA) below 33 weeks, who were born in Malmo 1986–1990. ROP developed in 27 (19%) of the 142 infants. The frequency of the ROP was significantly higher in infants with BW ≤ 1000 g (54%) and in those with GA ≤ 28 weeks (40%) than above these values. Infants with ROP had, compared with those without ROP, significantly lo...

A cohort of 169 very low-birthweight infants (800 to 1500g) was followed prospectively to the age of eight years. Information on 159 of the children was available at that age, and for a further five to the age of six years. A comparison group of 67 normal-birthweight children was also followed, but only 43 of these children were seen at the age of eight years. Eight of the very low-birthweight (VLBW) children were attending special schools and 156 attended normal schools: placement of the remain...

SUMMARY The ophthalmic findings in 127 very low-birthweight infants seen at a mean corrected age of 7.6 months (range one to 15 months) are presented and related to their neonatal findings on cerebral ultrasound scanning and eye examinations for retinopathy of prematurity. 19 infants (15 per cent) had significant ophthalmic abnormalities, including reduced visual acuity (11), squints (13), disorders of supranuclear eye-movement (three) and retinal abnormalities (eight). A strong association was ...

Introduction Prematurely born children have an increased risk of ophthalmologic problems. There is still no consensus on how they should be followed. The purpose of this study was to evaluate predictive factors for problems in premature children at ten years of age and to discuss follow-up recommendations. Materials and methods One hundred ninety-nine children with a birth weight of 1500 g or less were screened for retinopathy of prematurity (ROP) in the neonatal period and thereafter ophthalmol...

Changing preterm population variables have masked improvements in neonatal survival over time. Increased use of antenatal steroids, caesarean section, and surfactant may have reduced the likelihood of mortality and periventricular haemorrhage by a third and doubled that of chronic lung disease, persistent duct, and septicaemia.

Aims: To determine the refractive status and ocular dimensions of a cohort of children at age 10–12 years with birth weight below 1701 g, and also the relation between the neonatal ophthalmic findings and subsequent refractive state. Methods: 293 low birthweight children who had been examined in the neonatal period were assessed at 10–12 years of age. The examination consisted of autorefraction, keratometry, and A-scan. Results of right eyes were compared with published normative data. Results: ...

Objective To evaluate the refractive outcome in 10-year-old prematurely born children and in full-term control children. Methods Retinoscopy during cycloplegia was performed in 213 prematurely born children from a previous population-based study on the incidence of retinopathy of prematurity and in 217 children born at term. The spherical equivalent, astigmatism, anisometropia, and significant refractive errors (defined as hypermetropia >3 diopters [D], myopia ≤−1 D, astigmatism ≥1 D in 1 or bot...

Purpose : To prevent permanent visual disturbance, we performed a mass screening for the detection of ocular disorders of preschool children. Methods : Ocular examination was performed on 33,955 children in Seou(3~6 years of age)l, during the period from January to December, 2000. 435 children were shown to have either visual acuity of less than 0.5 or anisometropia of over 2 lines. Detailed Eye examination. was conducted on those 435 children. Results : Diagnoses consisted of refractive errors ...

Purpose To compare the surgical outcomes between pre- and full-term patients with exotropia and to examine the factors associated with surgical outcomes. Methods This retrospective study included 48 pre- and 432 full-term patients with basic-type exotropia who underwent unilateral or bilateral lateral rectus muscle (ULR or BLR) recession. Preoperative characteristics and surgical outcomes were compared between the pre- and full-term infants. Additionally, factors affecting the surgical outcomes ...
