H04.31 Phlegmonous dacryocystitis

Name of the Condition

• Phlegmonous Dacryocystitis

Summary

Phlegmonous dacryocystitis is a severe, suppurative inflammation of the lacrimal sac, characterized by the formation of a spreading, pus-producing infection. This condition involves acute bacterial infection and tissue inflammation, often leading to significant swelling, pain, and systemic symptoms if untreated. It typically arises from obstruction of the nasolacrimal duct, which traps tears and creates a breeding ground for bacteria.

Causes

Phlegmonous dacryocystitis is primarily caused by bacterial infection, most commonly from Staphylococcus or Streptococcus species, which thrive in the stagnant tears trapped by a blocked nasolacrimal duct. The obstruction may result from congenital abnormalities, chronic inflammation, or trauma. The infection progresses rapidly, leading to tissue destruction and pus formation within the lacrimal sac.

Risk Factors

• Chronic nasolacrimal duct obstruction or prior episodes of dacryocystitis.
• Immunocompromised states, such as diabetes or HIV.
• Recent eye or nasal surgery.
• Anatomical abnormalities of the lacrimal system.
• Bacterial colonization from adjacent sinus or nasal infections.

Symptoms

• Intense pain, swelling, and redness at the inner corner of the eye.
• Purulent (pus-like) discharge from the lacrimal punctum.
• Fever, chills, or general malaise due to systemic infection.
• Tenderness and warmth over the lacrimal sac area.
• Possible eyelid edema or cellulitis spreading to surrounding tissues.

Diagnosis

Diagnosis is based on clinical evaluation, including a physical examination of the eye and surrounding tissues to assess swelling, discharge, and tenderness. Cultures of the discharge may identify the causative bacteria. Imaging, such as dacryocystography or ultrasound, can confirm obstruction or abscess formation. Blood tests may be used to assess systemic infection.

Treatment Options

Treatment involves systemic antibiotics to target the bacterial infection, often administered intravenously in severe cases. Warm compresses and gentle massage may help promote drainage. In some cases, surgical intervention, such as incision and drainage or dacryocystorhinostomy, is necessary to relieve obstruction and prevent recurrence.

Prognosis and Follow-Up

With prompt treatment, most patients recover fully, though scarring or chronic obstruction may occur. Follow-up care includes monitoring for resolution of symptoms and assessing for recurrent infection. Long-term management may involve addressing underlying causes, such as anatomical abnormalities, to prevent future episodes.

Complications

• Spread of infection to surrounding tissues, including the orbit or face.
• Formation of lacrimal sac abscess or fistula.
• Chronic dacryocystitis or persistent tearing.
• Vision impairment if infection extends to the eye.

Lifestyle & Prevention

• Maintain good hygiene to reduce bacterial exposure.
• Address underlying conditions like allergies or sinusitis promptly.
• Seek early treatment for nasolacrimal duct obstruction to prevent infection.
• Avoid trauma to the eye or nasal area.

When to Seek Professional Help

Seek immediate medical attention if you experience severe eye pain, fever, or pus-like discharge, as these may indicate a serious infection requiring urgent treatment.

Tips for Medical Coders

When coding H04.31 (Phlegmonous dacryocystitis), ensure documentation specifies the acute, suppurative nature of the infection and confirms the involvement of the lacrimal sac. Note the presence of pus, systemic symptoms, or surgical intervention, as these details support the diagnosis. Verify that the condition is not classified under a more specific code for location or cause.
