Preparing patients for drug refractive cycloplegia
Keywords:refraction, drug cycloplegia, M-cholinolytics
One of the most important procedures in the ophthalmologist’s work is to determine the patient’s refraction. This procedure is necessary for patients of any age, because it helps to obtain information about whether the patient has refractive errors, whether they can become an obstacle to the normal formation of visual activity and binocular vision in preschool children, whether refractive errors are the cause of complaints of decreased vision and loss of visual performance (asthenopia) in older patients. The correct determination of static refraction, when the patient’s accommodation is completely relaxed, is not only of great importance at the time of deciding whether to prescribe optical correction — the obtained values are the basis for the clinical prescription itself. The paper presents modern methods for determining refraction, identifies indications for drug refractive cycloplegia, shows mydriatic and cycloplegic activity of M-cholinolytics, provides a comparative evaluation of different cycloplegic agents, recommended schemes of drug refractive cycloplegia.
