Homatropine
Uses of Homatropine
Homatropine is primarily used in ophthalmology for dilating the pupil for eye examinations and belongs to the group of anticholinergic medications.
It is also indicated for preventing the eye from focusing before and after certain eye surgeries and for managing eye inflammations like uveitis, iridocyclitis, keratitis and scleritis.
Side effects of Homatropine
Temporary blurred vision
Light sensitivity
Stinging or burning sensation in the eye
Eye redness or dryness
Headache
How Homatropine works
Homatropine is an anticholinergic medication.
It works by blocking the action of a neurotransmitter called acetylcholine in the eye. This results in the relaxation of the iris sphincter muscle and the ciliary muscle, both of which are essential for focusing the lens and controlling pupil size in the eye. Consequently, Homatropine causes dilation of the pupil (mydriasis) and temporary paralysis of accommodation (cycloplegia). These effects make it easier to examine the internal structures of the eye.
