Hypopyon: A Medical Condition Involving Eye Inflammation

Hypopyon is a medical condition characterized by the accumulation of inflammatory cells, specifically white blood cells, in the anterior chamber of the eye [1]. This condition is often accompanied by redness of the conjunctiva and underlying episclera, indicating inflammation of the anterior uvea and iris, also known as iritis or anterior uveitis [2].

Symptoms and Signs

A hypopyon occurs when exudate collects in the anterior chamber, appearing as a yellow-white fluid level in the inferior part of the anterior chamber [7]. This condition can be caused by various ailments, including eye infections, Behçet's disease, and other vision-threatening or life-threatening conditions [14].

Importance of Prompt Medical Attention

Recognizing the signs and symptoms of hypopyon is crucial for early diagnosis and treatment. If left untreated, this condition can lead to potential complications that may impair vision or even cause blindness or death [12]. Therefore, it is essential to seek medical attention immediately if you notice any signs of hypopyon.

Key Points

• Hypopyon is a condition characterized by the accumulation of white blood cells in the anterior chamber of the eye.
• It is often accompanied by redness of the conjunctiva and underlying episclera.
• A hypopyon can be caused by various ailments, including eye infections and Behçet's disease.
• Prompt medical attention is crucial for early diagnosis and treatment to prevent potential complications.

Visible Signs and Symptoms of Hypopyon

Hypopyon, an accumulation of leukocytes in the anterior chamber due to severe intraocular inflammation [5], can manifest in various ways. The following are some common signs and symptoms associated with hypopyon:

• White or yellow layer at the bottom of the eye: A noticeable white or yellow layer at the bottom of the eye's anterior chamber, easily observed by the patient or healthcare provider [2].
• Redness: The eye may appear redder than usual, indicating inflammation or irritation [2].
• Blurred vision: Difficulty seeing clearly due to the accumulation of leukocytes in the anterior chamber [1, 10].
• Eye pain: Pain or discomfort in the affected eye, which can be a sign of severe intraocular inflammation [3, 12].
• Light sensitivity (photophobia): Sensitivity to light, which can exacerbate the symptoms [1].
• Swollen eyelids (blepharitis): Swelling of the eyelids due to inflammation or irritation [1].
• Watery eyes (epiphora): Excessive tearing or watering of the eye due to irritation or inflammation [1].

Other Associated Symptoms

In some cases, hypopyon can be accompanied by other symptoms such as:

• Decreased vision: A decrease in visual acuity due to the accumulation of leukocytes in the anterior chamber [3].
• Conjunctival injection: Redness and swelling of the conjunctiva, which is the thin membrane covering the white part of the eye [4].

It's essential to seek medical attention if you experience any of these symptoms, as hypopyon can be a sign of a more severe underlying condition that requires prompt treatment.

Diagnostic Tests for Hypopyon

Hypopyon, a medical condition characterized by the accumulation of white blood cells or pus in the anterior chamber of the eye, requires accurate diagnosis to determine its underlying cause and effective management.

• Slit Lamp Examination: A slit lamp examination is essential to evaluate the anterior chamber and identify hypopyon. This test can often reveal the presence of hypopyon without magnification [2].
• Laboratory Tests: In cases where infection is suspected, laboratory tests such as cultures or polymerase chain reaction (PCR) can identify the causative agent [1]. These tests may include:
  • Cultures and smears for infectious keratitis or endophthalmitis [5]
  • Complete blood count, erythrocyte sedimentation rate (ESR

Treatment Options for Hypopyon

Hypopyon, an inflammatory condition characterized by the presence of white blood cells in the anterior chamber of the eye, can be effectively managed with various drug treatments.

• Topical Corticosteroids: These medications help reduce inflammation and prevent further damage to the eye. They are often used as a first-line treatment for hypopyon caused by iritis or other inflammatory conditions.
• Antibiotic Treatment: In cases where infection is identified as the cause of hypopyon, prompt antibiotic therapy is essential. Topical antibiotics may be administered to target the infectious agent and prevent further complications.
• Intravitreal Antibiotics: An injection of medicine directly into the vitreous (a clear gel between the lens and the retina) can be used to deliver antibiotics to the affected area.
• Antifungal or Antiviral Therapy: In cases where fungal or viral infections are suspected, antifungal or antiviral medications may be prescribed to target the causative agent.

Specific Medications Used

• Topical corticosteroids such as prednisolone acetate (1) and fluorometholone (3)
• Antibiotics like ciprofloxacin (2), ofloxacin (2), and moxifloxacin (2)
• Intravitreal antibiotics like vancomycin (12)

Important Considerations

• Treatment for hypopyon depends on identifying the underlying cause and addressing it appropriately.
• Prompt antimicrobial therapy is essential in cases where infection is identified as the cause of hypopyon.
• Topical atropine may be used to dilate the pupil, reduce ciliary muscle spasm, and prevent adhesion of the iris (5, 6).

Differential Diagnosis of Hypopyon

Hypopyon, which refers to the accumulation of fluid in the anterior chamber of the eye, can be caused by a variety of conditions. The differential diagnosis for hypopyon includes:

• Infectious causes: Endophthalmitis, infectious corneal ulcer, and fungal infections are all potential causes of hypopyon.
• Iritis and uveitis: Inflammation of the iris or uvea can lead to the accumulation of fluid in the anterior chamber.
• Retained intraocular foreign body: A foreign object left inside the eye can cause inflammation and lead to hypopyon.
• Phacolytic glaucoma: This is a type of secondary glaucoma that can cause hypopyon due to the blockage of the drainage angle in the eye.
• Masquerade syndromes: These are conditions that mimic other diseases, such as leukemia, lymphoma, retinoblastoma, melanoma, and metastasis, which can all cause hypopyon uveitis.
• Behçet's disease: This is a rare autoimmune disorder that can cause inflammation in the eyes, including hypopyon.
• Corneal ulcer: A corneal ulcer can cause hypopyon due to the infection and inflammation of the cornea.

According to [1], differential diagnoses include endophthalmitis, infectious corneal ulcer, severe iridocyclitis, retained intraocular foreign body, intraocular tumors, and others. The presence of hypopyon in a patient should prompt further investigation to determine the underlying cause.

In pediatric cases, hypopyon can be associated with a large number of differential diagnoses such as leukemia, anterior uveitis, and others [9].
