ABSTRACT: Acanthamoeba keratitis is a serious infection that can lead to loss of vision. It is highly challenging and often poses a diagnostic dilemma, causing delay in diagnosis and treatment. We report herewith the clinical and histopathology findings of a patient with an atypical presentation of acanthamoeba keratitis in Bahrain. The patient is a 16-year-old Bahraini teenager who was a cosmetic contact lens wearer. She presented with clinical signs and symptoms of microbial keratitis, which was initially misdiagnosed elsewhere as a case of herpetic corneal infection. Her corneal biopsy confirmed the clinical diagnosis as acanthamoeba keratitis. The patient was started on anti amoebic treatment. The infection got eradicated. The cornea healed with a central scar. Eventually, she underwent penetrating keratoplasty. This case report serves to raise awareness of this rare condition. Clinicians should have a high index of suspicion when diagnosing such cases among contact lens wearers. Early diagnosis and treatment are crucial to prevent serious complications.
