Glaucoma – a disease that occurs as a result of increased intraocular pressure (IOP), resulting in reduced visual acuity and an eye can appear a cloudy film, similar to cataracts. To reduce it, drugs from different pharmacological groups are used. Which means to use, prescribes an ophthalmologist, depending on the height of the values of the level of intraocular pressure and the presence of concomitant chronic diseases. It is important to consider the contraindications of each medication, so do not engage in self-medication.
Medicines should be effective enough so that they can maintain a normal level of IOP. The desired result is a reduction in intraocular pressure by 30% of the initial level or to 18 mm Hg or lower. If less effective medicines are required, second-choice drugs are used that reduce IOP by 20% of the baseline.
Also, with drug treatment, one should not forget about getting used to drugs and adjusting the choice of drugs with a decrease in effectiveness. If the replacement of the drug also does not contribute to an adequate reduction in IOP, then the drugs of the first and second choice or combined drugs are used. If there are side effects from the drugs of the first choice, the doctor prescribes treatment immediately with second choice medicines.
