孵育出１天的小鸡单侧眼睑缝合，饲养在光照与黑暗各为１２ｈ的环境中，４周未屈光检查为－１６．４Ｄ±＋６．６６Ｄ。另组缝合２周后剪开融合的眼睑，为－９．３４Ｄ±０．３４Ｄ的近视眼，保持双眼睁开继续饲养２周后屈光状态转变为＋ｌ．６６Ｄ＋０．８１Ｄ。说明眼睑缝合２周近视已经发生，饲养在正常情况下，近视迅速消失，表现为可逆性。眼睑缝合的同时每日结膜下注射阿朴吗啡２５０ｎｇ，４周后为＋０．６７Ｄ±０．０２Ｄ。抑制了近视的发生。眼睑缝合２周后每日分别注射２５０ｎｇ及５００ｎｇ阿朴吗啡持续２周，２组的屈光分别为－１１４３Ｄ±４．４７Ｄ及－６．８３Ｄ±４．７６Ｄ，而盐水对照组为－１８．５０Ｄ±６．３２Ｄ，说明在鸡视觉发育的不同时期，阿朴吗啡的局部应用具有抑制近视的发生及减缓近视发展的作用．
One-day-old chicks were sutured unilaterally and reared in an environment of 12 h light and dark, respectively. The 4-week no-refraction examination was -16.4 D ± + 6.66 D. Another group of sutures after 2 weeks cut the fusion eyelid, -9.34D ± 0.34D of myopia, keep your eyes open and continue feeding 2 weeks after the refractive state into + l. 66D + 0.81D. Description 2 weeks eyelid suture myopia has occurred, feeding under normal circumstances, the rapid disappearance of myopia, manifested as reversible. 250 ng of apomorphine was subconjunctivally injected at the time of eyelid suture, + 0.67D ± 0.02D after 4 weeks. Inhibit the occurrence of myopia. Two weeks after suturing, 250 ng and 500 ng of apomorphine were injected daily for 2 weeks. The refraction of the two groups was -1143D ± 4.47D and -6.83D ± 4.76D, respectively, while the saline control group was -18. 50D ± 6.32D, indicating that at different stages of chicken visual development, topical application of apomorphine can inhibit the occurrence of myopia and slow down the development of myopia.
