Abstract Nr.2023
ButEmphasize the severity of posterior segment complications after acanthamoeba keratitis.
MéthodesFollow-up of a patient with Acanthamoeba keratitis.
RésultatsA 36 year old male contact lens wearer presented with bilateral Acanthamoeba keratitis confirmed in the left eye by positive culture and PCR. After initiation of treatment with polyhexamethylene biguanide and propamidine drops, the keratitis right resolved fairly quickly but the keratitis in the left eye evolved with eventually the development of a painful anterior nodular scleritis. Besides the addition of topical steroids , oral steroids and eventually the use of oral azathioprine were needed to relief the pain. Despite prophylactic use of oral itraconazole, the sclerokeratitis evolved into a panuveitis with concomittant retinitis and papillary edema. Enucleation of the left eye was necessary because of severe pain and to prevent extra-ocular spread. Pathology confirmed the presence of acanthamoeba cysts in the sclera, retina and vitreous.
Because of anemia, thoracic imaging was performed which showed multiple lung nodules. Biopsy of those nodules showed hyphae, compatible with Aspergillosis pneumonia.
ConclusionScleritis, is a dreaded complication of Acanthamoeba keratitis, associated with a poor prognosis and a high rate of enucleation. Literature suggests immunosuppressive treatment to improve symptoms and to reduce the enucleation rate. This case study however indicates that systemic immunosuppressive treatment, even under prophylaxis of an antifungal agent, should always be used with greatest caution.
