Tropicamide - effective eye drops for diagnosis and treatment

Eye drops are used not only to relieve dry eye syndrome or treat various diseases.

There are such drugs that doctors use to diagnose and study the causes of visual impairment in patients.

One such is Tropicamide. Its main property is the ability to expand the pupil with a simultaneous obstacle to its narrowing.

This action of the drug is used in the practice of ophthalmology when it is necessary to examine the fundus and treat adhesions and inflammations of the eyes.

Instruction for use

Form of preparation and qualitycomposition

To date, the only drug form of release of Tropicamide is droplets. It is a colorless, clear liquid, packed in a plastic vial with a dropper dispenser.

Two dosage options are available - 0.5% active ingredient and 1%. In the first case, 1 ml of Tropicamide contains 5 mg of the active ingredient, in the second variant - 10 mg. The active ingredient is the chemical Tropicamide.

As auxiliary components are:

• sodium chloride( otherwise table salt),
• sodium EDTA,
• hydrochloric acid,
• benzalkonium chloride,
• deionized and highly purified water.

Therapeutic effect

Tropicamide is a member of the M-holinoblokatorov group. In other words, it has the ability to block M-holinoretseptory, available in the vessels and muscles of tissues with organs, including the iris of the eye and its ciliary muscle. The result of this action is the effect of relaxing the muscles for a short time.

When the iris and muscles relax, the pupil is maximally dilated with simultaneous muscle blocking( paralysis of accommodation), which are unable to respond at this time to changes in the light beam. That is, the maintenance of muscles in relaxation Tropicamide retains the pupil in an expanded form.

The pupil begins to expand after about 5-10 minutes. The maximum dilatation in the pupil is achieved after administration in 15-20 minutes. This condition lasts for an hour when instilled with 0.5% drops and for 2 hours from 1% of the composition. Normal recovery of the pupil occurs in 5-6 hours.

Often the effect of Tropicamide is compared with Atropine, which is stronger than ophthalmotonus. But such a relaxed effect does not exclude the possibility of increasing intraocular pressure.

Precautions

When you administer the medicine, you need to pinch the tear canal with your finger and hold it for two to three minutes. This measure serves to prevent solution from entering the nasopharynx from where it can completely absorb into the bloodstream.

Photophobia and a visual disturbance caused by instillation with Tropicamide alone pass after the end of the remedy.

If necessary, treatment of children under the age of 6 years, use Tropicamide 0.5%.To exclude the risks of systemic effects of the drug, it must be diluted with a physiological solution in a proportion of 1: 1. As a result, a 0.5% solution must be converted into 0.25%.Only in this form it can be buried in children. Dilute the drops with a sterile saline solution.

Combination with other medicines

If tropicamide is used together with neuroleptics, antidepressants and histamin blockers, then there is a mutual reinforcing effect from the effects of eye drops and these drugs.

Summation of Tropicamide with nitrites( eg, nitroglycerin) and glucocorticosteroids significantly increases intraocular pressure.

For whom the tool

is intended The drops are used for the purposes of:

• diagnosis,
• preparation for surgery,
• treatment.

From the point of view of diagnosis, Tropicamide is used for:

• eye lens check,
• examination of the fundus,
• for refractive analysis of the eye.

For surgical purposes, droplets are used for:

• cataract extraction, or eye lens surgery,
• retinal laser therapy( laserocoagulation),
• for vitreous surgery and ocular retina.

Treatment with eye drops suggests:

• complex therapy of eye inflammations( keratitis, uivitis, iridocyclitis),
• prophylaxis of synechia after surgical intervention.

How to use the drops

The traditional way of using eye drops is to instill them into the lower region of the conjunctival sac.

This procedure can be performed with a pipette or a special dropper attached to the vial.

1% solution is injected into the eye each drop by drop. Treatment lasts 2 - 4 weeks.

In case of using a dropper, it is best not to touch its tip. Otherwise, it can become contaminated and enter the eye of microbes. If you have contact lenses before the procedure, they need to be removed.

After half an hour after it, contact lenses can be worn. This applies to hard contact lenses. As for soft lenses, they should not be used at all during treatment. This is due to the danger of deposition of benzalkonium chloride on their surface.

Use in childhood

When treating children under six years of age, only drops of 0.5% Tropicamide can be used. To minimize the risk of side effects, the drug should be diluted with sterile saline in equal parts. Thus, a solution of a concentration of 0.25%, which is ideal for use in children, can be obtained. Bury the eyes of children preferably before going to bed. The drug should be injected one drop into each eye, and the duration of the therapeutic course should be from two to four weeks.

When using Tropicamide for the treatment of newborns, extreme care should be taken since this drug can cause a disorder of the central nervous system.

Degree of exposure

To maximize the pupil, a drop of a solution of 1% or two drops of 0.5% is enough. In the latter case, the interval between the drops should be about five minutes. After 10 minutes, the pupil is dilated, which makes it possible to perform diagnostics.

To investigate refraction, it is necessary to develop a paralysis of accommodation. To do this, 1% solution is injected into the conjunctival sac six times, one drop each, with a break of 6-12 minutes. Refraction can be investigated in the range of 25-50 minutes after the sixth drop.

Contraindications

Bovine eye Tropicamide is contraindicated in the presence of:

• closed-angle and mixed primary glaucoma,

Kinds of side effects of

Local effect is manifested by negative symptoms in the eyes and eyesight region:

• photophobia,
• accommodation disorder,
• increased ophthalmotonus,
• decreased visual acuity,
• burning in the eyes,
• attack of the closed-angle glaucoma,
• increased intraocular pressure.

Systemic adverse effects are possible if the agent enters the bloodstream in the form:

• obstructed urination,
• pressure drop due to vasodilatation,

The doctor warned that as a result of instillation, my eyesight may drop and a headache may appear( as the eye pressure rises).But the examination was easy, the vision did not change, and side effects did not occur.

# 2. The doctor advised me to drip into the eyes of Tropicamide, because the vision test produced poor results. At first I did not want to buy, as I read on the Internet that it was a narcotic substance. But all the same I bought it, which I did not regret. Vision quickly recovered.
