Abstract

Purpose: : To determine high-order aberrations and local refractive changes in premature children after diode laser for retinopathy of prematurity (ROP).

Methods: : We performed an analytic retrospective study of patients who underwent aberrometry. One hundred thirty eyes of 67 subjects (mean age, 6.73 ± 3.55 years) were examined at the Tokyo Metropolitan Ohtsuka Hospital in 2010. We analyzed the cycloplegic refractions (spherical equivalent [SE] and astigmatism) and high-order aberrations of the cornea and internal optics. All data were obtained by wavefront analysis (KR-9000PW Topcon, Japan) with a 6.0-mm optical zone. Patients were divided into three group based on ROP treatment: group 1, circumferential diode laser photocoagulation (28 eyes; gestational age, 25.1±1.3 weeks); group 2, hemispherical laser photocoagulation (30 eyes; gestational age, 26.7±1.7 weeks); group 3, no photocoagulation (42 eyes, gestational age, 27.0±1.8 weeks), and controls (30 eyes, preterm infants).

Results: : The average SE was -4.99±4.42 diopters (D) in group1, -1.18±2.88 D in group 2, +1.09±1.99 D in group 3, and +2.15±2.15 D in controls. The average astigmatism was -2.59±1.25 D in group 1, -1.30±1.04 D in group 2, -1.49±1.31 D in group 3, and -1.63±1.15 D in controls. The mean internal optical spherical aberration was 0.199 µm in group 1, 0.013 µm in group 2, -0.070 µm in group 3, and -0.137 µm in controls. The internal optical coma was 0.426 µm in group 1, 0.425µm in group 2, 0.426 µm in group 3, and 0.395 µm in controls. Group 1 had significantly higher internal optical spherical aberration than the others (P<0.01), but there was no significant difference in internal optical coma among the four groups (P>0.01). However, group 1 had lower corneal spherical aberration (0.066 µm) than the others (group 2, 0.160 µm; group 3, 0.200 µm; and controls, 0.178 µm). There was a positive correlation between the root mean square of the internal optical spherical aberration and the SE (r=-0.691, P=0.0003) and astigmatism (r=-0.527, P=0.0062) in group 1.

Conclusions: : Our results suggested that photocoagulation for premature infants might affect the internal optical spherical aberration.
