1/71. Resolution of microsporidial sinusitis and keratoconjunctivitis by itraconazole treatment.PURPOSE: To report successful treatment of ocular infection caused by the microsporidium encephalitozoon cuniculi in a person with acquired immunodeficiency syndrome (AIDS) and nasal and paranasal sinus infection. METHOD: Case report. RESULTS: Microsporidial infection in a person with AIDS and with chronic sinusitis and keratoconjunctivitis was diagnosed by Weber modified trichrome stain and transmission electron microscopy. Symptoms completely resolved with itraconazole treatment (200 mg/day for 8 weeks) after albendazole therapy (400 mg/day for 6 weeks) was unsuccessful. CONCLUSION: itraconazole can be recommended in ocular, nasal, and paranasal sinus infection caused by E. cuniculi parasites when treatment with albendazole fails.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/71. Corneal stromal calcification after topical steroid-phosphate therapy.Secondary corneal calcification involving the full thickness of the stroma is a rare potential complication of severe dry eye conditions, recurrent corneal ulcerations, chronic ocular inflammation, or multiple surgical procedures. We describe on a patient with unusual, hitherto unreported calcareous degeneration of the corneal stroma after topical steroid-phosphate therapy for chronic keratoconjunctivitis after stevens-johnson syndrome. The patient's serum levels of calcium and phosphorus were normal. Histopathologic and electron microscopic examination of the corneal button revealed mainly intracellularly located crystalline calcium deposits throughout all layers of the corneal stroma but sparing the Bowman layer. Energy-dispersive x-ray analysis confirmed the presence of calcium phosphate. The calcium deposits were closely associated with intracellular and pericellular accumulations of glycosaminoglycans. Our findings indicate that corneal stromal calcification may develop after topical steroid-phosphate medication, and suggest a possible role of alterations in the glycosaminoglycan metabolism of stromal keratocytes in the calcification process.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
3/71. The spectrum of ocular inflammation caused by euphorbia plant sap.OBJECTIVE: To report the spectrum of clinical findings in patients with ocular inflammation caused by plant sap from euphorbia species. DESIGN: Clinical case series. SETTING: ophthalmology emergency referrals in the United Kingdom. patients: We examined 7 patients, all of whom gave a history of recent ocular exposure to the sap of euphorbia species. INTERVENTIONS: All patients were treated with antibiotic drops or ointment (chloramphenicol). Cycloplegic and steroid drops were also used for some patients. patients were observed until all signs and symptoms had resolved. MAIN OUTCOME MEASURES: Symptoms, visual acuity, and clinical signs of inflammation. All patients provided a specimen of the plant for formal identification. RESULTS: Initial symptoms were generally burning or stinging pain with blurred vision. In most cases, visual acuity was reduced between 1 and 2 Snellen lines. In 1 patient with age-related maculopathy, acuity dropped from 20/80 to hand motions before recovering. Clinical findings varied from a mild epithelial keratoconjunctivitis to a severe keratitis with stromal edema, epithelial sloughing, and anterior uveitis. All signs and symptoms had resolved by 1 to 2 weeks. CONCLUSIONS: These cases illustrate the range of severity of euphorbia sap keratouveitis. The condition seems to be self-limiting when managed supportively. People who work with euphorbia plant species should wear eye protection. Clinicians managing keratopathy caused by euphorbia species should be aware of the danger of sight-threatening infection and uveitis, particularly during the first few days.- - - - - - - - - - ranking = 29.292466666158keywords = keratitis, ocular (Clic here for more details about this article) |
4/71. A case of keratoconjunctivitis due to Ewingella americana and a review of unusual organisms causing external eye infections.We report the isolation of Ewingella americana from the conjunctivae of a 38 year old female physician with keratoconjunctivitis associated with the use of soft contact lens. The patient was treated successfully with topical ciprofloxacin. The source of the infection remains unknown. All contact lens cleaning materials used by the patient were sterile. Since the patient was a physician, and this organism has been recorded as a cause of nosocomial infections, we checked whether cases of Ewingella americana had been reported, but none were identified. We have identified 39 bacterial species, 27 fungi, 4 viruses, 7 protozoa, 4 helminths, and 2 arthropods which rarely have been associated with keratitis or conjunctivitis. Infectious diseases specialists and ophthalmologists must be aware of the many different causes of this illness, including Ewingella americana. This organism is a rare bacterial cause of keratoconjunctivitis not previously reported in brazil. It should be added to the list of unusual cases of external eye infections.- - - - - - - - - - ranking = 26.292466666158keywords = keratitis (Clic here for more details about this article) |
5/71. Coexistent adenoviral keratoconjunctivitis and acanthamoeba keratitis.A 17-year-old youth presented with bilateral follicular conjunctivitis and nummular subepithelial corneal infiltrates. Failure of this to settle in an outpatient setting led to corneal scraping with microscopy and culturing for bacteria, fungi, herpes simplex, adenovirus and Acanthamoeba as an inpatient. polymerase chain reaction analysis of corneal cells was positive for adenovirus, and culture on live escherichia coli-coated agar plates was positive for Acanthamoeba by phase contrast microscopy on day two. We conclude that Acanthomoeba infection can complicate adenoviral keratoconjunctivitis. This observation is in keeping with previously reported modes of infection by Acanthamoeba, whereby any epithelial breach seems to allow inoculation of the eye by this opportunistic organism.- - - - - - - - - - ranking = 105.46968696316keywords = keratitis, simplex (Clic here for more details about this article) |
6/71. Recurrent phlyctenular keratoconjunctivitis: a forme fruste manifestation of rosacea.BACKGROUND: Phlyctenular keratoconjunctivitis represents a delayed type hypersensitivity response to a systemic antigen within the body. methods: We present a case of symptomatic, recurrent, phlyctenular keratoconjunctivitis in an 8-year-old child. The patient's inflammation responded favorably to topical steroids at each episode, but no specific antigen could be identified. CONCLUSION: After observing the father's erythematous facial lesions, we attributed the child's ocular inflammation to rosacea (as a forme fruste manifestation) and treated her with systemic erythromycin. The symptoms were rapidly relieved and the disease process was arrested.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
7/71. Microsporidial keratoconjunctivitis in a healthy contact lens wearer without human immunodeficiency virus infection.PURPOSE: To present a rare case of microsporidial keratoconjunctivitis in an otherwise healthy contact lens wearer without human immunodeficiency virus infection who responded to treatment with systemic albendazole and topical fumagillin. DESIGN: Interventional case report. METHOD: A cornea epithelial scraping from a man with unilateral keratoconjunctivitis previously treated with topical steroids was evaluated by modified trichome staining. MAIN OUTCOME MEASURES: The patient was evaluated for his symptoms, visual acuity, clinical observations, and pathologic examination of corneal scrapes. RESULTS: Modified trichome staining of an epithelial corneal scraping revealed pinkish to red organisms characteristic of microsporidia. Results of a human immunodeficiency virus (hiv) enzyme-linked immunosorbent assay test were negative. The symptoms of ocular discomfort and clinical signs of keratoconjunctivitis resolved after 2 months of treatment with albendazole and topical fumagillin. CONCLUSIONS: Ocular infection with microsporidia, although classically occurring in patients with hiv infection, may occur rarely in healthy individuals, especially if previously treated with systemic immune suppression or topical steroids. Microsporidial keratoconjunctivitis should be considered in the differential diagnosis of a contact lens wearer with atypical multifocal diffuse epithelial keratitis.- - - - - - - - - - ranking = 26.792466666158keywords = keratitis, ocular (Clic here for more details about this article) |
8/71. pseudomonas aeruginosa keratitis treated with ticarcillin and tobramycin.A corneal ulcer, infected with pseudomonas aeruginosa and complicated by conjunctivitis and endophthalmitis, was treated successfully with systemic administration of ticarcillin and topical application of tobramycin. It is unlikely that carbenicillin, to which the organism was much less sensitive, would have attained sufficient tissue levels to control the infection.- - - - - - - - - - ranking = 105.16986666463keywords = keratitis (Clic here for more details about this article) |
9/71. Microsporidial keratoconjunctivitis after HAART.A 44-year-old man presented with bilateral punctate corneal epitheliopathy complaining of worsening discomfort and photophobia over the previous several days. He was hiv positive, had a recent CD4 count of 4 x 10(6), and had started on highly active antiretroviral therapy (HAART) 14 days prior. Failure to respond to lubricant therapy with worsening of the epitheliopathy over the following week led to corneal biopsy and diagnosis of corneal microsporidiosis. Investigations revealed that he remained anergic and that his CD4 count had not changed. However, his viral load had decreased by at least 0.9 log10 units since HAART intiation. Therapy with albendazole led to complete resolution of his pre-existing symptoms of nasal congestion and epistaxis, as well as all recently occurring ocular signs and symptoms. It was concluded that the microsporidiosis was a pre-existing opportunistic infection, whose presence was unmasked by a form of immune restoration induced by HAART.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
10/71. Amniotic membrane in the surgical management of acute toxic epidermal necrolysis.OBJECTIVE: To report a new surgical technique to manage severe acute toxic epidermal necrolysis. DESIGN: Two interventional case reports. PARTICIPANTS: Two patients. Case 1: A 6-year-old boy had severe toxic epidermal necrolysis develop after being treated with trimethoprim and sulfamethoxazole for chronic otitis media. Both eyes and eyelids were affected. He underwent bilateral lysis of symblepharon and all adhesions and bilateral amniotic membrane transplantation to the entire ocular surface except the cornea. Loss of eyelid skin required transplantation of amniotic membrane to all four eyelids and strips of amniotic membrane at the eyelid margins. Case 2: An 8-year-old girl with severe toxic epidermal necrolysis associated with mycoplasma pneumonia had bilateral, diffuse keratoconjunctivitis, diffuse corneal epithelial defects, and bilateral symblepharon. Amniotic membrane transplantation was performed bilaterally, using a symblepharon ring in the left eye. INTERVENTION: Amniotic membrane transplantation. MAIN OUTCOME MEASURES: Preservation of normal ocular and eyelid surfaces and prevention of blindness. RESULTS: Case 1: Thirty-six months after bilateral ocular surgery, there is no symblepharon, good ocular surface wetting, and an uncorrected bilateral vision of 20/20. Case 2: Amniotic membrane transplantation protected both ocular surfaces and prevented conjunctival contracture without adhesion of the eyelids to the ocular surface. The central vision was preserved. There was minimal peripheral corneal vascularization and mild conjunctival scarring of the tarsal conjunctival surface 34 months postoperatively. CONCLUSIONS: These are the first cases of acute toxic epidermal necrolysis treated with amniotic membrane transplantation and the first use of the procedure on external eyelid surfaces with good healing of the eyelids. This new treatment for acute toxic epidermal necrolysis preserves normal ocular and eyelid surfaces and may prevent blindness.- - - - - - - - - - ranking = 3.5keywords = ocular (Clic here for more details about this article) |
