Conditions

Postoperative Neurocognitive Disorders

Brief summary

Long-term observation has shown that patients with visual impairment often develop cognitive impairments. Due to the fact that patients who are planning to undergo corneal transplantation may have initial cognitive deficits, assessing cognitive function is an important aspect of work for both the anesthesiologist and the operating surgeon. Given the high significance of assessing cognitive function after anesthesia in ophthalmic surgery patients, it is relevant to adapt and validate the Russian version of the MoCA Blind test for subsequent use in clinical practice.

Interventions

DIAGNOSTIC_TESTNeurocognitive testing

The psychometric properties of the Russian version of the MoCA Blind scale were evaluated according to the following parameters: reliability (reproducibility and internal consistency), validity (content and construct), and sensitivity.

Design outcomes

Primary

Measure	Time frame	Description
postoperative neurocognitive disorders	From the moment of inclusion in the study until the end of treatment 90 days later	Postoperative neurocognitive disorders were identified by comparing the results of neuropsychological tests performed before surgery and on the 90th day after surgery. An individual Z-score was used for each domain of the test.
