Abstract:
We report the evolution of clinical features of orbital implant infection in a 42-year-old man. Despite appropriate treatment recurrent conjunctival dehiscence could not be prevented. Explanation of the implant resulted in complete resolution of symptoms. Histopathological examination confirmed focal necrotising acute inflammation with the presence of colonies of the organism in the deep substance of the implant.
Insights
Orbital implant infection can cause recurrent conjunctival dehiscence despite treatment. Surgical removal of the orbital implant led to complete symptom resolution, confirming deep infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Surgical Pathology
Background:
- Orbital implants are used in ocular reconstruction.
- Infection of orbital implants is a potential complication.
- Recurrent conjunctival dehiscence can occur post-implantation.
Observation:
- A 42-year-old man presented with recurrent conjunctival dehiscence.
- Despite appropriate medical and surgical management, symptoms persisted.
- The patient had a history of orbital implant placement.
Findings:
- Histopathological examination revealed focal necrotizing acute inflammation.
- Microbial colonies were identified within the deep substance of the orbital implant.
- Surgical explantation of the orbital implant resulted in complete resolution of infection and dehiscence.
Implications:
- Orbital implant explantation may be necessary for refractory infections.
- Understanding the histopathological features aids in diagnosing deep implant infections.
- This case highlights the challenges in managing orbital implant infections.
