Abstract:
We describe a case of Candida parapsilosis endophthalmitis with a consecutive keratitis after phacoemulsification and posterior chamber intraocular lens implantation in an otherwise healthy eye. Despite aggressive medical and surgical management during a 2-year period, multiple episodes recurred, with the development of an intracapsular plaque and an infectious nidus on the corneal endothelium 6 months after the initial presentation. After subtotal removal of the culture-positive capsule, intravitreal and topical amphotericin B, and oral fluconazole, the inflammation improved. However, the corneal endothelial plaque persisted with recurrent inflammation 2 months later, prompting debridement of the culture-positive plaque and further removal of the culture-negative capsular remnants and lens implant. The infection was quiescent for the subsequent 12-month period until recurrent intraocular inflammation developed with enlargement of the endothelial plaque. Culture of this plaque was again positive for C. parapsilosis. After debridement and intraocular and topical amphotericin B, the eye has now been quiescent for 13 months. This case demonstrates the development of a secondary keratitis in an eye affected by pseudophakic C. parapsilosis endophthalmitis, with the posterior cornea serving as a sanctuary site for the fungus despite aggressive management leading to recurrent infection 1 year after the clinical disease appeared to be quiescent.
Insights
A rare case of Candida parapsilosis endophthalmitis led to keratitis after cataract surgery. The fungus persisted in the cornea, causing recurrent infections despite extensive treatment.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Phacoemulsification with intraocular lens implantation is a common cataract surgery.
- Endophthalmitis is a serious intraocular infection that can occur post-surgery.
- Candida parapsilosis is an opportunistic fungal pathogen.
Observation:
- A patient developed Candida parapsilosis endophthalmitis and subsequent keratitis after cataract surgery.
- Recurrent infections occurred over two years despite aggressive medical and surgical interventions.
- A fungal plaque formed on the corneal endothelium, acting as a sanctuary site.
Findings:
- Aggressive treatment with antifungal medications (amphotericin B, fluconazole) and surgical interventions were employed.
- The fungal plaque on the corneal endothelium contributed to persistent and recurrent inflammation.
- Cultures confirmed Candida parapsilosis in the plaque and capsular remnants.
Implications:
- This case highlights the potential for fungal sanctuary sites in the posterior cornea after intraocular surgery.
- Recurrent Candida endophthalmitis requires persistent and multifaceted management strategies.
- Understanding fungal behavior in the post-surgical eye is crucial for preventing vision loss.
