Rationale:
Fungal keratitis (FK) is a severe vision-threatening disease that can lead to corneal perforation or endophthalmitis despite proper treatment. It is important to diagnose the disease promptly due to its indolent nature and disproportionate disease symptoms. Trichosporon asahii is reported rarely as the causative organism of FK. We report a case of highly unusual bilateral T asahii keratitis following ptosis surgery.
Patient Concerns:
An 86-year-old female underwent bilateral levator resection surgery for ptosis. Postoperatively, the patient complained of gradually worsening bilateral ocular pain and a decrease in visual acuity associated with a chronic non-healing epithelial defect.
Diagnoses:
Both eyes of the patient were evaluated using best-corrected visual acuity, intraocular pressure, slit-lamp examination, fundus examination, and corneal culture. Multifocal deep stromal infiltrates were found in both corneas. Cultures from both corneal ulcers revealed growth of T asahii. Optical coherence tomographic examination showed bilateral macular edema.
Interventions:
The patient was treated with revisional ptosis surgery, an antifungal agent for the corneal ulcer, and intravitreal injection of steroid for macular edema.
Outcomes:
Both eyes recovered well. Her best-corrected visual acuity improved from 20/200 to 20/40 in the right eye and from 20/100 to 20/40 in the left eye.
Lessons:
FK can develop in the cornea when certain risk factors are present, including recent lid surgery, chronic keratitis, and steroid eye drop use. Identification and correction of risk factors can be beneficial in the treatment of FK.
Insights
This case report details a rare instance of bilateral fungal keratitis caused by Trichosporon asahii following ptosis surgery. Prompt diagnosis and treatment led to significant visual recovery in both eyes.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Fungal keratitis (FK) is a severe ocular infection that can lead to vision loss.
- Trichosporon asahii is an uncommon cause of fungal keratitis.
Observation:
- An 86-year-old female developed bilateral ocular pain and decreased vision post-ptosis surgery.
- Corneal cultures revealed Trichosporon asahii, and optical coherence tomography showed bilateral macular edema.
Findings:
- The patient presented with multifocal deep stromal infiltrates in both corneas.
- Treatment included revisional surgery, antifungal medication, and intravitreal steroids for macular edema.
Implications:
- This case highlights the risk of fungal keratitis after lid surgery, especially with chronic keratitis and steroid use.
- Early identification and management of risk factors are crucial for treating fungal keratitis.
