Mydriatic and cycloplegic agents can have different origins, and many of them are related to harmful substances, such as drugs. However, these effects they cause are not the intended consequence of the person taking them but rather a side effect.

Given its complexity and unconscious movements, the eye presents many difficulties for its physical study. In the ophthalmological field, a series of drugs are used, which, in this case, are specifically intended to offer a mydriatic and cycloplegic action.

If you do not know what it is, in the following FastlyHealarticle, we are going to give you the Definition of a mydriatic and cycloplegic agent; in turn, we are going to explain the functions that it is provided in the world of medicine and the effects it has on the organism.

What is a mydriatic and cycloplegic agent?

First of all, it is necessary to know that a mydriatic agent and a cycloplegic agent are not the same, although many times, the same agent can cause both. Unlike miosis, mydriasis is the increase in the diameter of the iris pupil when it is dilated more than usual due to a change in the light conditions outside or any other cause.

The process of accommodation of the lens is the body’s way of seeing clearly and clearly distinguishing objects close to us, preventing the gaze from blurring. The ciliary muscle, located inside the eyeball, makes this movement possible, accommodating the lens to the required shape depending on what is being observed. The cyclopedia is the paralysis of the ciliary muscle, and when this happens, the dilated pupil remains continuously.

The cyclopedic and mydriatic agent is understood to be the different pharmaceutical preparations that are used in ophthalmology to dilate the pupil and paralyze the ocular muscles that produce accommodation. Some can have the two effects simultaneously, although they may only cause one of the two.

Atropine, cyclopentolate, homatropine, scopolamine, and tropicamide are some of these topical ophthalmic solutions that produce a mydriatic and cycloplegic effect.

Role of cycloplegic mydriatic agents

You have already seen that mydriatics are drugs that stimulate or block the parasympathetic movements of the eye, which temporarily paralyzes the muscular sphincter of the iris. On the other hand, Cyclopedia paralyzes the accommodation of the ciliary muscle, but why are cycloplegia and mydriatics voluntarily induced at the ophthalmological level?

The reason for this is that this technique dramatically facilitates an examination of ocular refraction, allowing you to diagnose any ailment that you have in a much simpler way. Under these effects, the doctor can treat eye diseases such as uveitis or measure precisely any refractive defect in the eye, such as amblyopia. They are also mydriatic because to examine the retina, it is necessary to dilate the pupil. Otherwise, the examination cannot be performed correctly.

Side effects

Although some are more common than others and depending on the person, some or other effects may occur, resulting from mydriatic and cycloplegic agents, blurred visionthirst , red eyes, and fever.

It may also cause ataxia, drowsiness, or delusions among older and younger people.
