Abstract:
Objective To investigate the effect of cyclopentolate cycloplegic on the refraction measurement in adult guinea pigs. Design Experimental study.Participants 24 eyes of 12(10 weeks) adult guinea pigs.Methods 12 animals were randomly examined thrice by streak retinoscopy pre and post mydriasis.1%cyclopentolate hydrochloride was topically administrated to the eye every five minutes for three times.Main Outcome Measures The eye refraction of guinea pigs included the scope,cylinder and the equivalent power.Results The average refraction of guinea pigs in pre-mydriasis and post-mydriasis were 1.92?0.79 D and 2.08?0.79 D respectively. The average refraction that included the scope,cylinder and the equivalent power all showed no significant difference between pre and post mydriasis.The effect of mydriasis and measure time points on the refraction that included the scope,cylinder and the equivalent scope showed no significant difference either.Conclusions The effect of 1%cyclopentolate cycloplegic on adult guinea pigs in refraction is limited.The refraction of adult guinea pig can be measured naturally without cyclopentolate cycloplegic administrated.
