H16.029
Ring corneal ulcer, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
A ring corneal ulcer is a type of eye infection characterized by a circular, ring-shaped inflammation or ulceration of the cornea, which is the clear front surface of the eye. This condition can affect either eye and may lead to significant visual impairment if not properly managed. The term 'unspecified eye' indicates that the specific eye affected — right or left — is not specified in the diagnosis.
Causes & Symptoms
Clinical Causes: Bacterial infections, often caused by pathogens like Pseudomonas aeruginosa or Streptococcus species. Fungal infections resulting from fungi such as Aspergillus or Fusarium. Viral infections, including herpes simplex virus or herpes zoster virus. Contact lens misuse or poor hygiene, which increases risk by introducing pathogens. Trauma or injury to the eye that allows microorganisms to enter the cornea. Pre-existing eye conditions such as keratitis or previous corneal injuries. Compromised immune system, which weakens the body's ability to fight infection.
Key Symptoms: Pain or discomfort in the affected eye. Redness of the eye. Tearing or watering of the eye. Blurred or decreased vision. Light sensitivity (photophobia). Feeling of a foreign body or grit in the eye. Presence of a ring-shaped lesion visible on slit-lamp examination. Possible discharge from the eye, which may be mucous or pus-like.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination, including slit-lamp microscopy to identify the characteristic ring-shaped ulcer. Cultures of eye discharge or tissue samples may be taken to identify the infectious organism. Corneal scrapings can be examined microscopically to determine whether bacteria, fungi, or viruses are involved. Visual acuity tests help assess the extent of vision impairment, while additional tests may evaluate the severity of corneal damage.
Treatment Protocols: Treatment typically depends on the cause of the ulcer. Common approaches include:
