What are the Difference between Endophthalmitis and Panophthalmitis? Their Causes, Symptoms, and Treatment
DR. VATIKA JAIN In Eye Health
The human eye is a delicate and intricate organ susceptible to various eye infections. Among these, endophthalmitis and panophthalmitis are severe ocular conditions that require prompt medical attention. In this blog, we’ll understand what is Endophthalmitis and Panophthalmitis, their definitions, causes, symptoms, and treatment options for these sight-threatening infections, along with highlighting the difference between Endophthalmitis and Panophthalmitis.
They are serious eye conditions but they have some key differences. Endophthalmitis is an inflammation of the intraocular cavities, including the vitreous and aqueous humor. Panophthalmitis is a severe form of Endophthalmitis characterized by the rapid and extensive inflammation of all layers of the eye, including the sclera, uvea, and retina. It represents a severe and often fulminant infection that can lead to rapid destruction of ocular tissues and profound loss of vision.
Endophthalmitis is commonly caused by bacterial or fungal infections following eye surgery or trauma, hematogenous infection from distant sites, and intravitreal injections, although rare, can also cause endophthalmitis. Panophthalmitis is usually caused by severe bacterial infections that spread from the eye to the surrounding tissues such as the sinuses or orbit.
Symptoms of Endophthalmitis include sudden onset of severe eye pain, redness in the eyes, decreased vision or blurred vision, light sensitivity, floaters or spots in the vision, and tearing or discharge from the eyes. Panophthalmitis may also cause swelling and protrusion of the eyeball, along with systemic symptoms such as fever and malaise, elevated intraocular pressure, severe eye pain, loss of vision, and redness and swelling of the eyes.
Treatment for both conditions is urgent medical intervention, including intravitreal antibiotics and sometimes surgical drainage for Panophthalmitis. It’s important to seek immediate medical attention from the best eye doctors in India if you experience any symptoms of these conditions.
Difference between Endophthalmitis and Panophthalmitis
- Endophthalmitis primarily involves inflammation of the intraocular cavities, whereas panophthalmitis involves all eye layers, including the sclera and orbital tissues.
- Panophthalmitis is considered a more severe and fulminant form of infection than endophthalmitis.
- Panophthalmitis typically progresses more rapidly than endophthalmitis, leading to profound vision loss within a short period.
- Due to its aggressive nature, panophthalmitis requires more aggressive treatment modalities, including intravenous antibiotics, and may necessitate surgical intervention such as evisceration or enucleation.
Risk Factors for Endophthalmitis and Panophthalmitis
Certain factors predispose individuals to develop endophthalmitis or panophthalmitis. These may include a compromised immune system (such as in HIV/AIDS or immunosuppressive therapy), diabetes mellitus, pre-existing ocular conditions (like uveitis or diabetic retinopathy), and the presence of ocular implants or foreign bodies.
How to diagnose Endophthalmitis and Panophthalmitis
Diagnosing endophthalmitis and panophthalmitis relies on clinical examination, patient history, and diagnostic tests. Ophthalmologists typically perform a comprehensive eye examination, including visual acuity assessment, slit-lamp examination, intraocular pressure measurement, and fundus evaluation. Diagnostic tests such as ultrasound, optical coherence tomography (OCT), and microbiological cultures of intraocular fluids may aid in confirming the diagnosis and identifying the causative organism.
What are the Prevention Strategies for Endophthalmitis and Panophthalmitis
Some cases of endophthalmitis and panophthalmitis are unavoidable, certain preventive measures can reduce the risk of infection. These may include strict adherence to aseptic techniques during ocular surgery, prophylactic use of topical or intracameral antibiotics, meticulous wound care following trauma, and prompt treatment of systemic eye infections to prevent hematogenous spread to the eye.
Associated Complications
Both can lead to various complications, including irreversible vision loss, retinal detachment, choroidal detachment, optic nerve damage, and phthisis bulbi (shrinkage of the eyeball). In severe cases, intraocular inflammation may extend beyond the eye, causing orbital cellulitis, cavernous sinus thrombosis, or systemic sepsis.
Conclusion:
They are serious ocular infections that can result in significant morbidity and vision loss if not immediately diagnosed and treated. Understanding the causes, symptoms, and treatment options for these conditions is essential for ophthalmologists and healthcare providers to effectively manage these sight-threatening emergencies and preserve visual function in affected individuals. Early recognition and intervention are key to optimizing outcomes and minimizing long-term sequelae.
