vision/eye

vision/eye phenotype ( J:188632 )

N	• mice exhibit normal outer nuclear layer thickness, retinal outer segment length, photoreceptor numbers and rhodopsin complement

abnormal eye electrophysiology ( J:188632 )

abnormal rod electrophysiology ( J:188632 )

• mice exhibit loss of rod sensitivity with rod photoreceptor desensitization and faster response time to peak compared with Rho^tm1Phm heterozygotes

• rods exhibit a partially light-adapted phenotype

N	normal phenotype

vision/eye

vision/eye phenotype ( J:188632 )

N	• unlike other models of nightblindness, mice do not exhibit loss of rods

abnormal rod electrophysiology ( J:188632 )

• reduced dark-adapted b-wave threshold without rod degeneration

• rod sensitivity is depressed and required higher flash intensity

• for half maximal responses, the time to pear is faster than for wild-type mice
