UUnilateral corneal edema caused by a hidden foreign body

Area of Science:

• Ophthalmology
• Corneal Diseases
• Ophthalmic Surgery

Background:

• Unilateral corneal edema is a common presentation requiring investigation.
• Corneal transplantation is a potential treatment for severe corneal edema.
• Identifying the underlying cause is crucial for effective management.

Observation:

• A middle-aged male presented with unilateral corneal edema.
• Initial examination did not reveal a history of trauma.
• Gonioscopy identified a previously undetected foreign body in the anterior chamber angle.

Findings:

• Surgical removal of the intraocular foreign body was successful.
• The patient experienced good visual recovery post-surgery.
• The foreign body was the cause of the unexplained corneal edema.

Implications:

• Intraocular foreign bodies should be considered in cases of unexplained unilateral corneal edema.
• Thorough gonioscopic examination is vital for detecting subtle intraocular foreign bodies.
• Early diagnosis and surgical intervention can prevent the need for corneal transplantation and preserve vision.
