  2. The purpose of the training session: Doctors of any specialties need to know about such ocular pathology as diseases of the vascular tunic and cataracts. Often it is a local manifestation of many common diseases of the body: rheumatism, diabetes, tuberculosis, chronic and acute infectious disease, thyroid disease, etc. Doctors should be able to diagnose and treat patients with this pathology. It is also necessary to be able to carry out prevention of possible complications arising at these diseases.

  3. Pedagogical objectives:• Deepen knowledge on the clinical course of iridocyclitis and chorioretinitis and cataracts.• Develop the ability to select the correct algorithm of actions at iridocyclitis and cataracts.• Criteria for the diagnosis of complications of iridocyclitis and cataracts.• Tactics of GPs in acute iridocyclitis• Modern methods of treatment of cataract

  4. The student should be able to:• Identify risk factors at iridocyclitis and cataracts• Conduct clinical examination with laboratory and instrumental methods.• Disclose the criteria for diagnosis • • Make his/her own decisions and determine admission criteria in RMC (rural medical center).

  5. Learning outcomes:The student should know:• Clinical features of iridocyclitis, chorioretinitis and cataracts• Develop the ability to select the correct algorithm of actions at iridotsiklitah and cataract• diagnostic criteria for complications of iridocyclitis, chorioretinitis, and cataracts.• GPs tactics in acute iridocyclitis• Modern methods of cataract treatment
