Endophthalmitis vs Panophthalmitis – Key Differences

If you have sudden eye pain, blurred vision, or eye floaters, you may wonder how serious it is and how fast you should act. This guide explains endophthalmitis vs panophthalmitis in clear terms, outlines symptoms and causes, and shows how doctors treat each condition in India. Wherever you see endophthalmitis vs panophthalmitis, remember that both are ophthalmic emergencies requiring immediate care.

At Nethradhama Super Speciality Eye Hospital, specialists routinely manage complex eye infections like endophthalmitis and panophthalmitis to protect and restore vision.

What is Endophthalmitis?

Endophthalmitis is a severe eye infection inside the eyeball, involving the aqueous and vitreous (the eye’s internal fluids). It can occur after surgery or injections (exogenous) or spread from a bloodstream infection (endogenous). Typical red flags include rapid vision drop, pain, light sensitivity, and floaters. It demands urgent treatment to protect the retina and preserve sight.

Key facts:

• Definition: Purulent inflammation of intraocular fluids (vitreous and aqueous).
  
• Triggers: Most often postoperative, post-traumatic, or after intravitreal injections; less commonly from systemic infection (endogenous).
  
• Why it’s urgent: Delay can lead to irreversible damage to the retina and vision loss.
  

What is Panophthalmitis?

Panophthalmitis is an even more extensive eye infection. It inflames all coats and structures of the eye and often spreads to tissues around the orbit. Because it goes beyond the globe, it advances quickly and can threaten both vision and the eye’s integrity.

Key facts:

• Definition: Infection of the entire globe (cornea, lens, vitreous, choroid, retina, sclera) plus surrounding orbital tissues.
  
• Clinical course: Typically more fulminant than endophthalmitis, with rapid progression and severe pain.
  

Difference Between Endophthalmitis and Panophthalmitis

A concise way to read endophthalmitis vs panophthalmitis is to compare scope and spread of the infection. The table below summarises the difference between endophthalmitis and panophthalmitis.

Causes of Endophthalmitis and Panophthalmitis

Understanding triggers helps recognise risk and act fast—especially after procedures common in India, such as cataract surgery or anti-VEGF intravitreal injections.

Shared causes

• Postoperative: After intraocular surgery (e.g., cataract), microorganisms can enter despite sterile precautions.
  
• Post-traumatic: Penetrating eye injuries can seed bacteria/fungi.
  
• Endogenous: Infection from elsewhere in the body travels via blood to the eye (higher risk in uncontrolled diabetes, IV drug use, or systemic sepsis).
  

Why panophthalmitis develops

• Virulent organisms or delayed presentation can allow infection to extend beyond the globe, turning endophthalmitis and panophthalmitis difference into a severe clinical progression.
  
  

Symptoms to Watch Out For Panophthalmitis and Endophthalmitis

Act immediately if you notice any of the following after surgery, injections, or trauma. Quick action can save sight.

• Severe eye pain and tenderness
  
• Blurred vision or a sudden drop in vision
  
• Eye floaters, light sensitivity, or a “hazy” view
  
• Redness and eyelid swelling; sometimes discharge
  
• Systemic symptoms (fever, malaise) if infection is blood-borne
  

Both endophthalmitis and panophthalmitis are medical emergencies. Do not wait for symptoms to settle.

Endophthalmitis vs Panophthalmitis: Treatment Approaches

Management is urgent and tailored to the extent of the infection. For Indian patients, protocols align with international guidance and hospital expertise.

1. Endophthalmitis Treatment

• Immediate intravitreal antibiotics: Direct injection into the eye is the mainstay, covering Gram-positive and Gram-negative organisms.
  
• Early vitrectomy (case-dependent): Removing infected vitreous can reduce bacterial load, improve drug distribution, and help visual outcomes, especially with poor initial vision or significant vitritis.
  
• Systemic therapy: Selected cases may receive systemic antibiotics, but intravitreal drugs are primary.
  
• Work-up: Aqueous/vitreous tap for culture; B-scan ultrasound when media are hazy. Post-intravitreal injections, ophthalmologists follow defined endophthalmitis management protocols. If you’ve had intravitreal injections, cataract surgery, or eye trauma and develop pain with blurred vision or eye floaters, seek emergency care the same day.

2. Panophthalmitis Treatment

• Aggressive broad-spectrum antibiotics: Systemic plus intravitreal therapy is essential due to orbital involvement.
  
• Surgical intervention: If there is scleral necrosis, orbital spread, or the eye becomes unsalvageable, procedures like evisceration/enucleation may be considered to control infection and protect life.
  
• Supportive care: Pain control, hospital admission, and close monitoring in tertiary centres like Nethradhama Eye Hospital are crucial.

Patients diagnosed with endophthalmitis vs panophthalmitis at Nethradhama receive personalised care combining advanced imaging, laboratory diagnostics, and surgical expertise to control infection.

When to Seek Medical Help

Both endophthalmitis and panophthalmitis qualify as ophthalmic emergencies. The sooner treatment begins, the higher the chances of preserving vision and preventing permanent eye damage.

1. Timing is Critical
   Patients must seek medical care within hours of noticing symptoms like pain, redness, or blurred vision. In endophthalmitis, irreversible retinal damage can occur within 24–48 hours if antibiotic therapy or vitrectomy is delayed. In panophthalmitis, infection can spread rapidly to the orbital tissues and even the brain through venous channels, posing a risk of life-threatening complications.
2. Early Warning Signs
   
   Seek immediate ophthalmic evaluation if you notice:

• Increasing eye pain, swelling, or redness after surgery, injury, or intravitreal injections
  
• Sudden loss of clarity, eye floaters, or light flashes
  
• Yellow discharge or visible hypopyon (white layer in the lower part of the eye)
  
• Systemic symptoms like fever, chills, or malaise
  

3. Diagnostic Steps at the Hospital
   
   An ophthalmologist will typically perform:

• Slit-lamp examination to assess inflammation
  
• B-scan ultrasonography if the cornea or lens is too cloudy to view the retina
  
• Vitreous or aqueous sampling for culture and sensitivity tests
  
• Immediate intravitreal antibiotics if infection is suspected
  

4. Risks of Delay
   Delaying treatment can lead to retinal necrosis, optic nerve damage, or total loss of the eyeball in severe eye infections. Once panophthalmitis sets in, surgical options like evisceration may become unavoidable to control the infection.
