In each of the specific cases, the specialist individually selects the drug, dosage, the frequency of application and the duration of the course of treatment.Some eye diseases can not be diagnosed without the use of these drugs.

Features of preparations

Middriatics cause for a limited time a compulsory dilatation of the pupils. This allows the doctor to freely examine the internal structure of the eye. Drops for dilating the pupils can be of 2 kinds:

  1. Direct. Preparations of this group cause a contraction of the radial muscle of the eye. These include phenylephrine-based drugs, such as Irifrin;
  2. Indirect.Such drugs affect the circular muscle of the eye, relaxing it. They not only expand the icons, but also contribute to the adjustment of the focus of vision. These are eye drops, such as Midrum, Tropicamide or Cyclomide.

The effect of the use of eye drops, used primarily for examination of the fundus, remains.Drugs with the lowest dosage are used if an ophthalmoscopy is needed for a newborn or premature baby.
