Successful Topical Application of Caspofungin in the Treatment of Fungal Keratitis Refractory to Voriconazole
2010
Fungal keratitis is an important ophthalmic problem because it leads to corneal blindness and sometimes to loss of the eye.1,2 There is no agreed protocol for the treatment of suspected fungal keratitis. Topical and oral voriconazole have now been reported to be effective.3 However, some cases do not respond to this treatment. New antifungal agents such as caspofungin acetate, 0.5%, are promising alternatives
In vivo consequences of cholesterol-24s-hydroxylase (CYP46A1) inhibition by voriconazole on cholesterol homeostasis and function in the rat retina
2011
Cholesterol 24S-hydroxylase (CYP46A1) converts cholesterol into 24S-hydroxycholesterol in neurons and participates in cholesterol homeostasis in the central nervous system, including the retina. We aimed to evaluate the consequences of CYP46A1 inhibition by voriconazole on cholesterol homeostasis and function in the retina. Rats received daily intraperitoneal injections of voriconazole (60mg/kg), minocycline (22mg/kg), voriconazole plus minocycline, or vehicle during five consecutive days. The rats were submitted to electroretinography to monitor retinal functionality. Cholesterol and 24S-hydroxycholesterol were measured in plasma, brain and retina by gas chromatography-mass spectrometry. T…
Fungal Necrotizing Scleritis After Intravitreal Injection Therapy
2020
PURPOSE To report a case of infectious necrotizing scleritis secondary to Aspergillus terreus after intravitreal injection therapy. METHODS This is a case report with literature review. RESULTS A 98-year-old woman receiving intravitreal aflibercept injections for neovascular age-related macular degeneration in the left eye presented with severe pain, redness, and purulent discharge at the injection site. She was initially treated with topical fortified antibiotics, and clinical improvement was achieved, although microbial cultures showed negative results. Two months later, she presented with severe ocular pain and was diagnosed with anterior necrotizing scleritis. Scleral scrapings were col…
