Cortical blindness: the changing incidence and shifting etiology

Area of Science:

• Neurology
• Ophthalmology
• Critical Care Medicine

Background:

• Cortical blindness is a neurological disorder typically resulting from cerebrovascular accidents, cardiorespiratory arrest, severe head trauma, or bacterial meningitis.
• The traditional understanding of cortical blindness etiology is based on these severe neurological insults.
• Effective cardiopulmonary resuscitation (CPR) techniques have advanced significantly, potentially altering patient outcomes and disease incidence.

Observation:

• This report details three distinct cases of cortical blindness.
• These cases are presented in the context of recent advancements in resuscitation methodologies.
• The presented cases may indicate a change in the typical incidence and causes of cortical blindness.

Findings:

• The incidence and etiology of cortical blindness may be evolving.
• The development and widespread use of effective cardiopulmonary resuscitation might be a contributing factor to this potential shift.
• Analysis of these three cases suggests a need to reconsider the factors leading to cortical blindness.

Implications:

• Healthcare providers should be aware of potential changes in the etiology of cortical blindness.
• Further research is warranted to confirm the impact of CPR advancements on cortical blindness incidence.
• Understanding these evolving patterns is crucial for accurate diagnosis and effective treatment strategies for visual impairment following critical events.
