Explanation:
A mydriatic drug is used to induce dilation of the pupils to visualize and examine the retina and other deep and posterior structures of eye clearly during an ophthalmic examination.
Mast cell stabilizer drugs are chromone medications which are prescribed for treating allergic disorders. They act by blocking the cellular processes of mast cells like degranulation, stabilization, and release of histamines and other allergy-related mediators during an allergic reaction or disorder.
Silver nitrate is put into neonate’s eyes immediately after birth to prevent any bacterial eye infections. This will pain the neonate’s eyes which will make it to close the eyes. This will prevent the initial eye contact and bonding between the mother and the child.
Vitrasert or Ganciclovir is an antiviral agent used to treat cytomegalovirus (CMV) infections like CMV retinitis. Vitrasert is actually an implant (placed surgically at the posterior eye) which diffuses Ganciclovir slowly into the infected site in the eye.
