Abstract:

Objective

The aim of this study was to investigate refractive status of infants at 6-week-old and evaluate feasibility and effectiveness of using SureSight vision screener to screen infants′ refractive status.

Methods

A retrospective research involved 481 infants (962 eyes) who were born in Beijing Tongren Hospital from Apr. 2015 to Aug. 2016. Infants aged 6 weeks around were underwent refractive screening using SureSight vision screener. Retinoscopy optometry were applied when refractive value were exceeded the measurement range of the equipment. Basic information of newborns was collected, including birth weight, birth length, gender, laterality, delivery methods, pre-term or not, and family history of high myopia.

Results

Among of 481 infants (962 eyes), refractive power cannot be measured in 16 infants (32 eyes, 3.3%) using SureSight vision screener. One infant (1 eye) with vitreous hemorrhage cannot be detected either by SureSight vision screener or by retinoscopy optometry. The rest of 480 infants (961 eyes) were included. Spherical equivalent power was (+ 3.632±1.272) D. The maximum power was + 8.00 D and the minimal power was -3.25 D. Nine infants (11 eyes) were under 0 D and 5 infants (10 eyes) were more than + 6.00 D. Spherical equivalent power did not related to birth weight or birth length (r=-0.017, -0.003; P>0.05). Spherical equivalent power of male and female infants were (+ 3.568±1.334) D and (+ 3.704±1.196) D; spherical equivalent power of right and left eyes of infants were (+ 3.631±1.273) D and (+ 3.634±1.272) D; spherical equivalent power of spontaneous labor and cesarean section infants were (+ 3.711±1.194) D and (+ 3.574±1.325) D ; spherical equivalent power of premature and mature infants were (+ 3.634±1.276) D and (+ 3.599±1.255) D. There were no statistically differences in spherical equivalent between right and left eyes, male and female, spontaneous labor and cesarean section, premature and mature infants (t=-1.656, 0.038, -1.662, 0.348; P>0.05). Spherical equivalent powers of family high myopia history and without family history infants were (+ 3.346±1.214) D and (+ 3.689±1.276) D. Spherical equivalent powers were lower in infants with family high myopia history than those without family history (t=-3.112, P<0.05).

Conclusions

Most infants at 6-week-old were hyperopia. Refractive status was related to family history of high myopia, and was not related to birth weight, birth length, gender, laterality, delivery mode, or premature. Using SureSight vision screener for infants refraction screening is convenient and effective, which can help to monitor and intervene vision development at an early age.
