Introduction:

Commotio retinae, also known as Berlin's edema or retinal concussion, is a transient and self-limiting condition of the retina that occurs due to blunt trauma to the eye. This injury results in temporary visual disturbances and is considered a form of retinal contusion. This article aims to provide a comprehensive understanding of commotio retinae, including its causes, symptoms, and management strategies.

Causes of Commotio Retinae:

Commotio retinae is primarily caused by blunt force trauma to the eye, which leads to the transmission of shockwaves through the ocular tissues, including the retina. Common causes of commotio retinae include:

• Sports-related injuries: Impact from balls, racquets, or accidental collisions during sports activities can cause retinal concussions.
• Accidents: Industrial accidents, motor vehicle collisions, or falls can result in ocular trauma and commotio retinae.
• Physical assaults: Blows to the eye during altercations can also lead to this condition.

Symptoms of Commotio Retinae:

The symptoms of commotio retinae typically develop immediately or shortly after the injury and may include:

• Blurred vision: The individual may experience a sudden decrease in visual clarity.
• Photopsias: Some individuals may see flashes of light or flickering sensations.
• Floaters: Small, dark spots or floaters may be perceived in the visual field.
• Central scotoma: A central area of reduced or absent vision may be present due to retinal involvement.

Diagnosis of Commotio Retinae:

The diagnosis of commotio retinae is made based on a comprehensive eye examination and the patient's history of recent ocular trauma. The ophthalmologist will assess visual acuity, perform funduscopy, and may use additional imaging techniques such as optical coherence tomography (OCT) or fluorescein angiography to evaluate retinal integrity and identify any associated retinal abnormalities.

Management of Commotio Retinae:

Commotio retinae is typically a self-resolving condition, and the management approach focuses on supportive care and observation. Treatment may include:

• Rest and observation: Most cases of commotio retinae improve spontaneously over time, and visual disturbances resolve without specific intervention.
• Symptomatic relief: Over-the-counter pain relievers may be used to alleviate any discomfort associated with the injury.
• Follow-up examinations: Regular follow-up appointments with an ophthalmologist are essential to monitor the progress of the condition and ensure no complications arise.

Prevention of Commotio Retinae:

While it may not always be possible to prevent commotio retinae due to accidental trauma, individuals engaging in sports or activities with a risk of ocular injury can take preventive measures:

• Protective eyewear: Wearing appropriate sports goggles or safety glasses can provide significant protection against blunt force trauma to the eyes.
• Safety measures: Adhering to safety guidelines and using appropriate protective equipment in industrial or construction settings can reduce the risk of ocular injuries.

Conclusion:

Commotio retinae is a transient condition of the retina caused by blunt force trauma to the eye. While the symptoms are often self-resolving, timely evaluation by an ophthalmologist and supportive care are essential. Preventive measures, such as using protective eyewear, can significantly reduce the risk of commotio retinae and promote ocular safety during sports and potentially hazardous activities.
