Keratitis
• 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.
• 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
• 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).
• 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
