Used primarily in ophthalmology, this compound serves as a mydriatic and cycloplegic agent. It is applied in eye examinations to dilate the pupil and temporarily paralyze the ciliary muscle, allowing for accurate assessment of the retina and refractive errors. Its action is faster and shorter compared to atropine, making it suitable for diagnostic procedures where prolonged pupil dilation is not desired. It may also be used in the treatment of inflammatory eye conditions like uveitis to prevent complications from ciliary spasm. Available in solution or ointment form, it is administered topically to the eye.
