Oral Miltefosine as Adjunctive Treatment for Recalcitrant Acanthamoeba Keratitis
Conclusions: This case shows resolution of recalcitrant Acanthamoeba keratitis with oral miltefosine in an immunocompetent patient. Further clinical evidence would be needed to possibly incorporate this medication in the antiamoebic armamentarium.

Patients who underwent TPK at National Taiwan University Hospital in 2001–2014 were included. Patients were divided into 3 diagnostic groups: bacterial keratitis, fungal keratitis, and acanthamoe...
This patient with recurrent unilateral ocular complaints, a lid lesion, and keratitis unresponsive to numerous medications as well as a negative work-up for infectious agents leaves us with numerous diagnostic possibilities. These include: viral shedding from the lid lesion as with molluscum, eyelid deformity with corneal exposure, limbal stem cell deficiency of uncertain etiology, ocular surface dysplasia or neoplasia, superior limbic keratoconjunctivitis, vernal keratoconjunctivitis, herpes group viruses, Acanthamoeba keratitis, eyelid foreign body, medicamentosa, and many others.

To report the clinical and microbiological features of Acanthamoeba keratitis (AK) related to contact lens use in a tertiary hospital in China.
Conclusions: In an in vitro assay, voriconazole reduced the cysticidal activity of 2 commonly used antiamoebic drugs. Although the in vivo drug interactions could be different, these observations may be useful in cases of nonhealing Acanthamoeba keratitis being treated with combination therapies that include voriconazole.
CONCLUSION: PHMB 0.02% monotherapy for the initial treatment of AK is as effective as biguanide+diamidine combination therapy. Chlorhexidine monotherapy was too infrequent for comparison. The outcome data are the most detailed available. PMID: 31401556 [PubMed - as supplied by publisher]

ConclusionPKP à chaud within 5.3 months after first symptoms of therapy-resistant AK seems to result in better final BCVA than delayed graft surgery if the disease is resistant to a classical topical triple therapy. In addition, early PKP may have a favorable impact on epithelial healing and graft survival.FundingWe thank the Alexander von Humboldt Foundation for supporting the work of Prof. N.
