Patching is not always the first step: an amblyopia course built around the cause

The course Amblyopia: Mechanism, Forms, Diagnosis and the Evidence Base for Treatment was published on 30 September 2026 in English and Russian. Its catalogue card lists 26 lessons and 147 minutes of study. After the introduction come four modules of five lessons each: the visual system and the critical period; the forms of amblyopia and their causes; diagnosis by acuity, refraction and binocular function; and treatment, split into what is proven, what is promising and what does not work. Each module ends with an eight-question checkpoint with a pass mark of 70%. The final exam has 25 questions, a pass mark of 75% and two attempts; by the course's own description at least a third of them are case analyses. The clinical cases in the lessons are generalised teaching constructs and are labelled as such.

Guideline editions and evidence sources, named on the first page

The definition comes from the American Academy of Ophthalmology's Amblyopia Preferred Practice Pattern, which the course calls AAO Amblyopia PPP 2022 (Updated 2024): the text published in Ophthalmology in March 2023, with its February 2024 revision. The course takes its numbers from that PPP together with the Pediatric Eye Evaluations PPP (Table 2, February 2026 revision), publications of the Pediatric Eye Disease Investigator Group (PEDIG) and Cochrane reviews. The introduction also records that no separate current clinical protocol of the Ministry of Health of the Republic of Kazakhstan on amblyopia was found, and that the 2015 protocol on strabismus in children refers to the 2012 edition of the PPP, which the academy has since replaced.

Preparation for a seminar on a child's vision

The first three lessons open without an account: who the course is for and what it leaves out; amblyopia as a disorder of the cortex rather than of the retina; and what exactly breaks in binocular vision. The second lesson sets out the rule that the diagnosis is not made without an amblyogenic factor and a matching acuity deficit; the third explains why sensory binocular tests are done before occlusion and the cover test. From the fourth lesson on, the page invites the reader to register, and after registration they return to the course already enrolled.

Where the modules fit into the timetable

• Ophthalmology cycle for years 4–6: the diagnosis module — examination plan, acuity with crowding, cycloplegic refraction, binocular function, differential diagnosis — before the practical session on testing children's vision, with its checkpoint as the entry test.

• Paediatrics residency: the module on forms by cause, because the first step differs from form to form — removing a cataract, prescribing glasses and patching the fellow eye are three different starts.

• Ophthalmology residency: the treatment module — optical correction as the first treatment, occlusion doses that have been compared head to head, atropine as an equal regimen with a different harm profile, and a lesson that sorts lines of treatment into proven in randomised trials, under investigation and not supported.

What stays outside the course

The platform library has no ophthalmology virtual-patient scenario, so this course is reading and assessment rather than a case to manage. It does not teach strabismus surgery or the surgery of congenital cataract, where deprivation appears only as a cause of amblyopia and an argument for urgency. It follows the PPP population of patients up to and including 17 years; adult residual amblyopia appears only as a research horizon, not as a treatment standard.
