TACOMA, Wash. (KTLA) -- A 29-year old woman has pleaded not guilty to first-degree child assault after allegedly pouring bleach into her toddler's eyes.
The investigation began last summer when Jennifer Mothershead's 15-month-old daughter was treated for a head injury.
During the examination, doctor's realized that the toddler's previously diagnosed eye condition had worsened.
The girl was diagnosed with an eye infection in March 2011, KOMO television reported.
According to KOMO, Mothershead told doctors at the time that the toddler had scratched her eye while playing in a barn and was given antibiotics and eye drops to treat the injury.
Mothershead admitted that she had given the child eye medication.
But when hospital staff and detectives examined the eye drops, they noticed a strong odor.
A detective said the drops caused a minor burning sensation when placed on his wrist.
The drops were latter determined to contain bleach.
Prosecutors say the amount of damage to the child's eyes was inconsistent with accidental exposure.
The victim, who is now 2 years old, sustained permanent vision damage.
The girl is now living with her biological father.
