amphotericin-b and Corneal-Opacity

To describe a rare case of early-onset Candida parapsilosis infection after laser in situ keratomileusis (LASIK) and review the published reports of post-LASIK fungal infections.. A 32-year-old woman presented with interface infiltration in the central interface in the right eye 2 days after LASIK surgery. The right eye flap was lifted, and the opacities were scraped. Two days later, a 3- x 3-mm-dense oval opacity and diffuse hazes were noted. Surgical intervention was arranged because of suspicion of interface infectious keratitis.. After an apparent post-LASIK keratitis with related interface inflammation failed to respond to medical therapy, corneal culture results were positive for C. parapsilosis 2 weeks 6 days after presentation. The patient was started on topical drops of amphotericin B 0.15% every hour after the smear showed the presence of yeast. The opacities decreased, and the topical antifungal drops were tapered. One month later, her uncorrected visual acuity recovered to 20/20.. Candida parapsilosis interface keratitis after LASIK may occur in the early phase. Early diagnosis and proper treatment can result in good outcome.

To report the case of a patient developing fungal keratitis in the context of uncontrolled ocular cicatricial pemphigoid (OCP), which, despite intravenous immunoglobulin (IVIg) and other immunomodulatory therapy, progressed to end-stage pemphigoid, with corneal opacification, ankyloblepharon, and xerosis. Keratoprosthesis (KPro) restored functional vision for the patient.. A 39-year-old man presented with uncontrolled CP and corneal ulcer in the left eye. Conjunctival biopsy diagnosed OCP; corneal scraping and biopsy diagnosed the cause of the corneal ulcer. OCP was treated with systemic steroids, immunosuppressive drugs, and IVIg. Visual rehabilitation was accomplished with Ahmed valve and a type II Dohlman KPro.. Immunohistology of the biopsied conjunctiva showed IgG at the epithelial basement membrane zone, confirming the clinical diagnosis of OCP. Microbiologic studies of the corneal biopsy specimen were negative for Acanthamoeba and herpes but positive for Aspergillus niger. The patient's keratomycosis resolved with topical antifungal therapy. Treatment with Dapsone, intravenous-pulse steroid, oral cyclophosphamide, and intravenous immunoglobulin (IVIg) failed to control the OCP, with resultant complete conjunctivization of the cornea. Keratoprosthesis improved the patient's visual acuity from hand movements to 20/20.. Patients with uncontrolled OCP are at increased risk of corneal infection. The difficulty in diagnosing keratomycosis and the relatively rare occurrence of OCP explain the uniqueness of our reported case. OCP may progress to "end-stage" disease despite therapy. Keratoprosthesis can restore vision in selected otherwise seemingly hopeless cases.

Severe eye burns occur rarely, but are related to a poor prognosis in rehabilitation. As emergency treatment has been identified as decisive factor for the prognosis of eye burns, new first aid rinsing solutions should be considered carefully in their clinical action. In a first approach, the new drug Diphoterine was subjected to a comparison with saline solution to evaluate the effects in a model of severe eye burns.. In a double-masked experiment 16 rabbits underwent a severe eye burn of one cornea followed by immediate rinsing with 0.9% sodium-chlorine solution (n=8) or Diphoterine (n=8). During 16 days after burn, an irrigation therapy with 0.9% saline solution three times daily 160 ml was applied in both groups following the recommendation of prolonged irrigation therapy performed in our clinic. In a similar setup, 16 eyes were subjected alkali burns with measurements of aqueous humor pH within 30s after burn and after a period of 5 min rinsing with 500 ml saline 0.9% or Diphoterine, respectively.. The result of the severe eye burn with an opaque cornea was similar in both groups. During rinsing no fibrin precipitates occurred in the Diphoterine rinsed group whereas this was detectable in all eyes rinsed with saline solution. After 16 days there was no difference between both groups indicating no harmful effect of Diphoterine as emergency treatment compared to saline 0.9%. After 30s of burn with 1N NaOH and rinsing with 500 ml of the specified solutions the anterior chamber pH was 10+/-0 in the saline group and 9.35+/-0.3 in the Diphoterine group showing efficacy of the buffering capacity of Diphoterine.. Diphoterine proves to be efficient in the primary treatment of burns. The anterior chamber pH could be lowered by 5min of rinsing. No harmful effects of Diphoterine could be observed compared to rinsing with saline solution in the course of an severe alkali burn of the cornea.

6 months before admission a 21-year-old woman had developed anogenital condylomata acuminata (CA). Since early childhood she had been treated for primary hypoparathyroidism (PHPT) and recurrent mucocutaneous candidiasis. 5 years before admission corneal clouding had caused visual impairment. Recently, mainly truncal vitiligo with occipital poliosis had developed.. PHPT was confirmed (parathormone level 7.7 mg/l). In addition, liver transaminases were raised (GOT 105.8 U/l, GPT 145.6 U/l, gamma-GT 56.8 U/l), pointing to noninfectious hepatitis. An ACTH stress test could not exclude manifest adrenocortical insufficiency, and thyroid function was also normal. The Merieux Multitest indicated an anergy.. The constellation of test results suggested autoimmune polyglandular syndrome type I. The condylomata were treated by electrocautery and the intestinal candidiasis with amphotericin B suspension. Calcitriol capsules, 0.5 microgram, and calcium gluconate or lactate, 500 and 300 mg respectively, 3 times daily each, were given for the PHPT.. This case demonstrates a complex syndrome which can be recognized early by simple clinical tests. Early diagnosis prevents possible life-threatening complications.
