Overview
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 test Neurocognitive 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.
Primary outcome measures
- postoperative neurocognitive disorders [Time frame: From the moment of inclusion in the study until the end of treatment 90 days later]
Eligibility criteria
Inclusion criteria
- patients with corneal pathology, including burns, ulcers, dystrophies, and keratoectasia, as well as those with a history of corneal injuries
- physical status of I-III on the ASA scale.
Exclusion criteria
- children
- patients with sensorineural hearing loss
- patients with chronic cerebrovascular disorders
- patients with initially high levels of anxiety and depressive symptoms
- patients with severe cognitive impairments.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
