Changes

Accommodation is similar to mammals with changes in the shape of the lens. Unlike mammals, this is under voluntary control by the action of the striated radial muscles within the ciliary body. Mammalian mydriatics therefore do not work in reptiles.  However, d-tubocurarine has been used for mydriasis in reptiles.  The injection of 0.05 to 0.1ml via a 27-30g needle into the anterior chamber results in mydriasis for 30 minutes to several hours.  Reptiles have a rapid direct light reflex but no consensual light reflex.
