Summary
Surgically induced scleritis (SIS) is a rare complication. This case highlights that surgery on one eye may trigger SIS in both eyes, even in previously asymptomatic eyes with a history of severe inflammation.
Area of Science:
- Ophthalmology
- Immunology
Background:
- Surgically induced scleritis (SIS) is an uncommon post-operative complication following ocular procedures.
- Most reported cases involve patients with a history of multiple prior surgeries.
Observation:
- A 64-year-old male presented with unilateral red eye and tenderness.
- The patient had undergone uneventful cataract surgery in the right eye five months prior.
- The left eye had a history of vision loss 25 years earlier with no prior ocular symptoms for two decades.
Findings:
- The patient developed diffuse scleritis in the right eye five months post-cataract surgery.
- Scleritis subsequently appeared in the left eye three months later.
- This represents a novel instance where unilateral ocular surgery appears to have induced bilateral scleritis.
Implications:
- This case suggests that surgical trauma in one eye can potentially trigger scleritis in the contralateral eye.
- The contralateral eye may be susceptible even with a history of prior severe inflammation and long-term quiescence.
- Further investigation is warranted to understand the mechanisms underlying surgery-induced bilateral scleritis.
