Endophthalmitis leading to unilateral blindness?
Hello, doctor.
My family member, who is 70 years old, developed endophthalmitis after cataract laser surgery.
They underwent vitrectomy and removal of the infected intraocular lens, along with retinal surgery.
The attending physician informed us that there is a severe retinal tear and the chance of vision recovery is very low (even if a new lens is implanted, they may only perceive faint light).
They have been discharged one month after becoming blind in one eye and are still using the antibiotic eye drops prescribed by the original hospital.
The original physician indicated that the endophthalmitis has been treated, and we are now waiting for the swelling of the eyelid and the blood vessels in the eye to gradually recover.
Recently, a doctor at a nearby ophthalmology clinic advised that the blind eye is no longer useful and that surgery for removal should be performed as soon as possible; otherwise, it could affect the other currently healthy eye (due to the risk of optic neuritis) or even the brain.
Is it possible for such a situation to occur? Can an infection in one eye potentially affect the other eye or even the brain? Are the interiors of the two eyes interconnected? Thank you, doctor.

Hello Lillian: This type of intraocular inflammation usually does not affect the other eye.
The condition described by the physician typically occurs in cases of severe ocular trauma leading to "sympathetic ophthalmia," although even sympathetic ophthalmia is quite rare.

Post-cataract endophthalmitis is a serious complication that can occur after cataract surgery, characterized by inflammation of the interior of the eye, often due to infection. This condition can lead to significant vision loss and may require aggressive treatment, including vitrectomy (removal of the vitreous gel) and the removal of infected intraocular lenses. In your case, it seems that your family member underwent such procedures due to severe endophthalmitis following cataract surgery.
The risks associated with endophthalmitis include not only the immediate threat to vision but also the potential for systemic complications. While the eyes are anatomically separate, they are connected through the bloodstream and can share certain systemic responses to infection. However, the direct transmission of infection from one eye to another is rare. The primary concern is that an infection in one eye could lead to complications that may affect the overall health of the patient, including the risk of spreading infection to other parts of the body, such as the brain, particularly if the infection is severe and left untreated.
In your family member's case, the recommendation to consider enucleation (removal of the eye) is likely based on the severity of the infection and the lack of functional vision in that eye. If the eye is deemed non-viable and poses a risk to the other eye or the patient’s overall health, the surgical removal may be necessary to prevent further complications.
It is essential to follow the advice of the ophthalmologist regarding the management of the affected eye. If there is any indication that the infection could spread or if there are signs of complications affecting the other eye, prompt action is crucial. Regular follow-ups with an eye care professional are necessary to monitor the condition and to ensure that any potential complications are addressed swiftly.
In terms of the connection between the eyes, while they do not directly communicate, they are part of the same visual system and share similar vascular supplies. Therefore, an infection in one eye can potentially influence the health of the other eye, especially if there is a systemic response to the infection.
In summary, while the risk of one eye's infection directly affecting the other eye is low, the overall health implications of a severe infection necessitate careful monitoring and management. If there are concerns about the health of the other eye or systemic issues, it is vital to consult with an ophthalmologist who can provide a comprehensive evaluation and appropriate treatment options.
