Summary
Temporary bilateral corneal denting occurred in a patient after cardiovascular surgery under general anesthesia. This rare ocular event may be linked to anesthesia-induced ocular hypotension.
Area of Science:
- Ophthalmology
- Anesthesiology
- Cardiovascular Surgery
Background:
- Cardiovascular surgery, particularly thoracic aorta aneurysm repair, involves complex procedures often requiring general anesthesia.
- General anesthesia utilizes various agents that can potentially impact intraocular pressure and corneal physiology.
Observation:
- A 71-year-old male presented with immediate bilateral corneal denting and ocular hypotension post-cardiovascular surgery.
- Delayed emergence from anesthesia precluded immediate visual assessment.
- Ocular morphology and pressure normalized post-operatively after topical ophthalmic application.
Findings:
- The case highlights a transient, bilateral corneal indentation following major cardiovascular surgery.
- Ocular hypotension was a significant finding concurrent with the corneal changes.
- The corneal abnormalities resolved spontaneously within 24 hours.
Implications:
- Corneal denting may be an under-recognized complication of general anesthesia in specific surgical contexts.
- Anesthesia-induced ocular hypotension could be a contributing factor to corneal structural changes.
- Awareness among anesthesiologists and ophthalmologists is crucial for prompt diagnosis and management.

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
