H18.12
Bullous keratopathy, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Bullous keratopathy is a condition where the cornea—the clear front surface of the eye—becomes swollen and develops blister-like bubbles. When it affects the left eye specifically, it can lead to discomfort, visual disturbances, and potential vision loss. This condition usually results from endothelial cell loss, which impairs the cornea's ability to keep itself clear and properly hydrated.
Causes & Symptoms
Clinical Causes: Fuchs' endothelial dystrophy Previous eye surgery, such as cataract removal Corneal trauma or injury Infections affecting the corneal endothelium Certain eye diseases that damage the corneal tissues
Key Symptoms: Blurred or cloudy vision Sensitivity to light Seeing halos or glare around lights Itching or burning sensation in the eye Swelling or blistering on the cornea Discomfort or mild pain in the affected eye
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough eye examination, including slit-lamp microscopy to observe the corneal surface. An ophthalmologist may also perform corneal pachymetry to measure thickness and specular microscopy to assess endothelial cell health. These tests help confirm the presence of bullous keratopathy and evaluate its severity.
Treatment Protocols: Treatment options depend on the severity of the condition. Mild cases may be managed with hypertonic saline eye drops or ointments to reduce corneal swelling. More advanced cases may require surgical intervention, such as a corneal transplant or endothelial cell transplantation, to restore corneal clarity and function. Additionally, protecting the eye from further injury and minimizing inflammation are important aspects of managing the condition.
