ABSTRACT
Due to the advantages in genetic manipulation, mice have become one of the most commonly used mammalian models for the study of mechanisms underlying myopia development. However, the vast majority of laboratory mouse strains are incapable of synthesizing melatonin, a neurohormone that may play an important role in myopia generation in humans. The present study investigated refractive development profiles in the CBA/CaJ mouse, a strain proficient in melatonin, and determined whether and how its refractive development could be affected by form-deprivation. Eccentric infrared photoretinoscopy revealed that this animal could be stably refracted, and the refractive error underwent developmental changes, which increased with age in the hyperopic direction and eventually got stable approximately 9 weeks after birth. The absolute values of refractive error in CBA/CaJ mice were larger than those of age-matched C57BL/6 mice, whereas the time points when refractive error reached steady state were similar between the two strains. Five weeks of form-deprivation applied to 3-week-old CBA/CaJ mice by translucent occluder wear caused a significant myopic shift in refractive error, indicating that this strain could be adequately used as a myopia model.
