Dacryocystitis

Overview

Dacryocystitis is inflammation of the lacrimal sac, the structure that receives tears before they drain through the nasolacrimal duct into the nose. When the drainage pathway is obstructed, tears stagnate and bacteria can proliferate. Acute dacryocystitis is usually painful and inflamed, while chronic disease may present mainly with tearing, discharge and recurrent low-grade irritation. ^{[1] [2]}

In adults, acquired nasolacrimal duct obstruction is the common background problem. In infants, congenital obstruction near the distal duct can cause persistent tearing and recurrent infection. Bacteria in retained tears trigger inflammation of the sac and surrounding tissues. If infection extends beyond the lacrimal system, preseptal or orbital cellulitis and abscess can develop. ^{[1] [2]}

The location of swelling is diagnostically helpful: dacryocystitis classically affects the area below the inner corner of the eye near the side of the nose. A red swollen upper eyelid or diffuse orbital symptoms suggest other diagnoses. Chronic tearing without marked pain may represent obstruction without acute infection, which is managed differently from a hot tender lacrimal sac. ^{[1] [2] [3]}

Symptoms and warning signs

Acute symptoms include tenderness, redness and swelling over the lacrimal sac, excessive tearing and mucous or purulent discharge. Pressure over the sac can sometimes express material from the puncta. Fever may occur in more severe infection. Chronic disease may cause recurrent tearing, sticky discharge and intermittent swelling rather than dramatic pain. ^{[1] [2]}

Reduced vision, painful eye movements, proptosis, marked eyelid swelling, severe headache, systemic toxicity or rapidly spreading redness are warning signs for orbital cellulitis or deeper infection. These features require urgent ophthalmic or emergency assessment because orbital complications can threaten vision and spread intracranially. ^{[1] [2]}

Diagnosis

Most cases are diagnosed clinically from the typical history and location of tenderness. Visual acuity, pupils, eye movements and the globe itself should be assessed to ensure the problem is confined to the lacrimal drainage system. In acute disease, expressed purulent material can be sent for culture when infection is severe, recurrent or not responding to empiric therapy. ^{[1] [2]}

Imaging is not routinely required for uncomplicated dacryocystitis. CT may be used when orbital extension, trauma, atypical anatomy, tumor or deep abscess is suspected. After acute inflammation settles, lacrimal irrigation, probing or formal drainage-system evaluation can define the site of obstruction before definitive surgery. ^{[1] [2] [3]}

Differential diagnoses include preseptal cellulitis, orbital cellulitis, infected epidermoid cyst, sinus disease, hordeolum, canaliculitis and lacrimal-sac tumor. A mass above the medial canthal tendon, bloody tears or persistent firm swelling is atypical and can prompt investigation for neoplasm or another structural lesion. ^{[2] [3]}

Causes, risk factors and clinical context

Adults with chronic tear-duct obstruction are at risk of recurrent episodes. Nasal or sinus disease, prior facial trauma and surgery can alter drainage anatomy. Infants with congenital obstruction commonly have tearing but only a subset develop acute infection. Older age is associated with acquired nasolacrimal obstruction. ^{[1] [2]}

Acute infection often improves with antibiotics and warm compresses, but recurrence is common if the underlying obstruction remains. Chronic obstruction can produce repeated infections or persistent tearing. Definitive correction of drainage anatomy is therefore an important part of long-term management in adults with recurrent disease. ^{[1] [2] [3]}

Complications and why the diagnosis matters

Complications include lacrimal-sac abscess, fistula, preseptal or orbital cellulitis and, very rarely, cavernous sinus thrombosis, meningitis or sepsis. Manipulation or probing during active acute inflammation is generally avoided because friable infected tissue can be injured and infection may spread. ^{[1] [2]}

Prognosis is usually good when infection is treated and the obstruction is ultimately corrected. Children with congenital obstruction often improve spontaneously during the first year of life, whereas adults with persistent acquired obstruction commonly require a procedural solution for durable relief. ^{[1] [2] [3]}

Treatment and management

Acute uncomplicated dacryocystitis is treated with systemic antibiotics targeting common skin and respiratory bacteria, along with warm compresses and analgesia. Severe infection, systemic illness or orbital extension can require intravenous therapy and hospital care. Drainage may be needed if a localized abscess forms. ^{[1] [2]}

Definitive management addresses the blockage. In adults, dacryocystorhinostomy creates a new drainage pathway and is commonly used when obstruction persists. In children, conservative massage is often tried first for congenital obstruction, followed by probing or other procedures if symptoms continue. Timing depends on age, severity and recurrence. ^{[1] [2] [3]}

Forceful massage or probing of a very inflamed lacrimal sac should not be improvised at home. Eye redness with visual symptoms needs ophthalmic assessment because a deeper orbital process can mimic or complicate dacryocystitis. Antibiotic choice should account for allergy, local resistance and severity. ^{[1] [2]}

Follow-up, recovery and prevention

Follow-up confirms that pain, swelling and discharge are resolving and that vision remains normal. Recurrent episodes should prompt evaluation of the drainage system. After DCR or probing, follow-up focuses on patency and control of nasal or sinus contributors to obstruction. ^{[1] [2]}

There is no reliable way to prevent every episode when an anatomic obstruction is present. Managing chronic nasolacrimal blockage is the main recurrence-prevention strategy. Good hand hygiene around infant eye discharge and avoiding unnecessary manipulation of the lacrimal sac can reduce secondary irritation. ^{[1] [2] [3]}

Special situations and care pathway

Infants differ from adults because congenital nasolacrimal obstruction often resolves with growth. Adults with bloody tears, an atypical firm mass or recurrent unilateral disease need careful structural evaluation. Immunocompromised patients may have atypical organisms or more aggressive infection. ^{[1] [2] [3]}

The care pathway separates uncomplicated sac infection from orbital disease: confirm the typical medial swelling, check vision and eye movements, treat acute infection, image only when complications or atypical features are present, then evaluate and correct the underlying drainage obstruction once inflammation is controlled. ^{[1] [2]}

When to seek urgent medical care

Seek urgent assessment for vision loss, painful or restricted eye movement, proptosis, severe eyelid swelling, high fever, confusion or rapidly worsening facial redness. Those findings are not typical of isolated uncomplicated dacryocystitis. ^{[1] [2]}
