We encountered a patient who developed Bacillus cereus endophthalmitis following trauma. Early therapy, which included intravitreal clindamycin phosphate and gentamicin sulfate, resulted in a visual acuity of 20/60. A five-year retrospective review of all cases of endophthalmitis following trauma reported at our institution revealed Bacillus as the infecting organism in six (46%) of 13 culture-positive cases. The high frequency of virulent Bacillus infections in the setting of trauma necessitates the use of antibiotics that are active against this organism in posttraumatic endophthalmitis. The combination of clindamycin and gentamicin can be effective therapy in Bacillus species infections if used early in the course of the disease.

Purpose: To report the unusual occurrence of a recurrent scleral abscess after uncomplicated cataract extractionMethods: Case report of a 77-year-old healthy woman.Results; Multiple cultures and antibiotic treatments failed to resolve presenting symptoms. Gram stain, Gomori methenamine silver (GMS) stain, and all cultures were negative. After drainage of the abscess, the patient's symptoms cleared briefly, then returned 6 months later showing a positive GMS stain consistent with Candida. The patient was treated with amphotericin, natamycin, and fluconazole at this time, and a return in visual acuity occurred along with a resolution of symptoms. No reoccurrence has been noted with 2.5 years of follow-up.Conclusions: Cataract extraction, although generally a safe procedure, can still result in unusual complications such as scleral abscesses. Excellent outcomes are possible once the infections are identified and treated.

A 10-year-old boy with a past medical history significant for chicken pox at 7 years of age was referred to our eye center by an outside ophthalmologist for a 15-day history of worsening right-sided preseptal cellulitis. The patient reported photophobia, pruritus, and pain in the eyelid region. There appeared to be vesicular lesions on the eyelids. Empiric therapy with oral antibacterial and antiviral medications failed to resolve the preseptal cellulitis. Lid cultures revealed coagulase negative Staphylococcus, Streptococcal viridans, and a Trichophyton species of fungus. The infection was successfully treated with two courses of oral itraconazole. This is the first case of preseptal cellulitis caused by this dermatophyte that we could find in the literature.

PURPOSE:To report two cases of ring infiltrates in disposable contact lens wearers resembling Acanthamoeba keratitis but later identified as fungus.METHODS:We report two patients with histories of disposable soft contact lens use, who, on initial presentation, were found to have corneal ring infiltrates and were treated for presumed Acanthamoeba keratitis. Microbiological studies, which included Gram stain and Gomori methenamine silver stain, as well as blood agar, chocolate agar, thioglycolate broth, Sabouraud agar, nonnutrient agar with Escherichia coli overlay, and Lowenstein-Jensen plates, were performed.RESULTS:Microbiological studies revealed fungi in both cases.CONCLUSIONS:Fungal keratitis is an uncommon complication of disposable soft contact lens use, but it should be considered in the differential diagnosis of corneal ring infiltrates.

PURPOSE To report the first case of fungal keratitis in a patient wearing daily disposable soft contact lenses. METHODS Case Report. A 20-year-old white female in good health developed a corneal ulcer in her lefteye associated with daily disposable soft contact lens wear. There was no history of trauma to the left eye, and she denied overnight wear. Corneal scrapings were taken, and the patient was started on intensive tobramycin 14 mg/mL and cefazolin 50 mg/mL topical therapy for suspected bacterial keratitis. After 3 days of antibacterial therapy, the ulcer worsened. The cultures were negative as were the Gram stain and Gomori's methenamine silver stain. Initial cultures and stains were then repeated with the addition of a culture for herpes simplex virus. The developing clinical picture was suspicious for fungal keratitis. The patient was then started on intensive vancomycin 2%, natamycin 5%, and continued on fortified tobramycin. Three days after the second corneal scrapings were performed, a positive fungal culture was obtained for Fusarium sp. Vancomycin and tobramycin were then discontinued and amphotericin B 0.15% was added to natamycin 5% with the continuation of intensive topical therapy. RESULTS The patient's keratitis was successfully treated with intensive double antifungal therapy. CONCLUSIONS Infectious keratitis in daily disposable soft contact lens wear is an unusual occurrence. To our knowledge, there is no previous case of fungal keratitis occurring in patients wearing daily disposable lenses. This case emphasizes the importance of considering fungus in the differential diagnosis for keratitis even in daily disposable contact lens wearers.

PURPOSE:To report an unusual case where the diagnosis of hemophilia was made after attempted penetrating keratoplasty in an elderly patient.METHODS:A 75 year old white male with a full-thickness corneal scar in the visual axis and a visually significant cataract OD was to undergo penetrating keratoplasty and cataract extraction with lens implantation for visual rehabilitation. There was no history of bleeding diathesis given.RESULTS:During placement of the Flieringa ring, a progressively enlarging 360 degrees subconjunctival hemorrhage was observed. Given the unusual bleeding,the procedure was aborted and the patientwas referred to the hematology service for further evaluation. Laboratory studies revealed a diagnosis of atypical hemophilia of mild severity.CONCLUSIONS:The initial diagnosis of hemophilia in any elderly patient is unusual. This case is even more unusual asthe diagnosis of a bleeding disorder was first considered after excessive subconjunctival hemorrhage developed during attempted penetrating keratoplasty.

PURPOSE:To report a case of fungal keratitis resulting after laser in situ keratomileusis (LASIK).METHODS:A 38-year-old white man in good health developed a corneal infiltrate with laboratory confirmation of fungal keratitis after LASIK. Corneal scrapings were taken. Silver stain was positive for hyphae. Culture was positive for Curvularia sp. The patient was started on intensive natamycin 5% and amphotericin 0.15% topical therapy.RESULTS:The patient's keratitis was successfully treated with intensive antifungal therapy.CONCLUSIONS:Infectious keratitis is a rare but a serious potential complication after LASIK. To our knowledge, no previous case of fungal keratitis after LASIK has been reported. This case emphasizes the importance of surveillance for infection after LASIK.

PURPOSE To report a case of Mycobacterium chelonae keratitis after laser in situ keratomileusis successfully treated with medical therapy and flap removal. METHODS Case report. A 36-year-old white woman in good health developed a paracentral keratitis in her right eye 1 month after bilateral laser in situ keratomileusis. Initial treatment included topical steroids and then intensive Ocuflox (ofloxacin ophthalmic solution; Allergan, Inc, Irvine, California) without success. Cultures were negative. The keratitis worsened, and she was referred to our institution. Interface infiltration was noted, and the flap was lifted to obtain adequate laboratory studies. Cultures were positive for M chelonae. RESULTS The keratitis was treated with intensive topical amikacin sulfate 1%, topical clarithromycin 1%, and Ciloxan (ciprofloxacin HCL; Alcon Laboratories, Inc, Fort Worth, Texas) with minimal improvement in her clinical condition. She developed a toxic reaction to amikacin 1%. In order to improve antibiotic penetration, the hazy, ulcerated corneal flap was removed. The keratitis then resolved with intensive topical clarithromycin 1% and Ocuflox over 5 weeks. The patient now has visual acuity without correction of 20/50, despite superficial corneal haze. CONCLUSION M chelonae is a rare and insidious cause of infection after laser in situ keratomileusis. Diagnosis can be difficult and is often delayed. Aggressive medical management, with flap removal, if needed, may lead to resolution of infection.

PURPOSE: To report a case of severe cicatricial conjunctivitis in a patient with lichen planus, which is known to affect the skin and mucous membranes. The conjunctival immunopathologic features were consistent with lupus erythematosus rather than with lichen planus.METHOD: Oral mucosal and skin biopsies were performed with histopathologic and immunofluorescent studies consistent with lichen planus. The patient later had a biopsy of cicatrized conjunctiva with histopathologic and immunofluorescent findings consistent: with lupus erythematosus. Evaluation by rheumatology and dermatology consultants demonstrated no evidence of active systemic lupus erythematosus or discoid lupus erythematosus.RESULTS: The patient was treated with topical and systemic immunosuppressives and her disease eventually stabilized.CONCLUSION: The case demonstrates two coexisting autoimmune disease entities: lichen planus of the skin and oral mucosa and a cicatricial conjunctivitis consistent: with lupus erythematosus.

PURPOSE: To evaluate the relationship between microbiologic factors, effect of treatment, and visual outcome in the Endophthalmitis Vitrectomy Study.METHODS: Four hundred twenty patients were enrolled in the Endophthalmitis Vitrectomy Study between February 1990 and January 1994. Of these, 394 completed 9 to 12 months of follow-up. Patients presented with features of bacterial endophthalmitis within 6 weeks of cataract extraction or secondary intraocular lens implantation. The relations between visual outcome and the identity of infecting species, gram stain results, antibiotic susceptibilities, and presence of vitrectomy cassette growth were examined.RESULTS: Rates of achieving final visual acuity of 20/100 or better for the more common isolates were as follows: gram-positive, coagulase-negative micrococci, 84%; Staphylococcus aureus, 50%; streptococci, 30%; enterococci, 14%; and gram-negative organisms, 56%. A positive gram stain or infection with species other than gram-positive, coagulase-negative micrococci were significantly associated with poorer visual outcome (P <.001 for species group comparisons). However, presenting visual acuity was more powerful than microbiologic factors in predicting visual outcome and favorable response to vitrectomy. Bacterial growth from the vitrectomy cassette specimen had prognostic significance equivalent to growth from other intraocular sources.CONCLUSIONS: Visual prognosis was strongly associated with the type of infecting organism and gram stain positivity. However, visual acuity at initial presentation appeared to be more useful than microbiologic factors in predicting visual outcome and judging the value of immediate vitrectomy in acute bacterial endophthalmitis after cataract surgery.

Seven patients with documented Acanthamoeba keratitis were treated with prolonged and intensive triple antiamoebic therapy consisting of topical neomycin-polymyxin B-gramicidin, propamidine isethionate 0.1%, and miconazole nitrate 1%. Additionally, five patients were treated with topical corticosteroids. Six of seven patients were cured of Acanthamoeba keratitis with medical therapy alone, one patient required therapeutic penetrating keratoplasty to eradicate the infection. Two patients underwent penetrating keratoplasty to improve their vision after medical therapy. Our series differs from previous reports in that triple antiamoebic therapy was used in all seven patients and was successful in both early and advanced cases of Acanthamoeba keratitis. Prolonged and intensive topical therapy with these three antiamoebic drugs may be an effective mode of therapy for Acanthamoeba keratitis.

Objective: To determine the roles of immediate pars plana vitrectomy (VIT) and systemic antibiotic treatment in the management of postoperative endophthalmitis.Design: Investigator-initiated, multicenter, randomized clinical trial.Setting: Private and university-based retina-vitreous practices.Patients: A total of 420 patients who had clinical evidence of endophthalmitis within 6 weeks after cataract surgery or secondary intraocular lens implantation.Interventions: Random assignment according to a 2 X 2 factorial design to treatment with VIT or vitreous tap or biopsy (TAP) and to treatment with or without systemic antibiotics (ceftazidime and amikacin).Main Outcome Measures: A 9-month evaluation of visual acuity assessed by an Early Treatment Diabetic Retinopathy Study acuity chart and media clarity assessed both clinically and photographically.Results: There was no difference in final visual acuity or media clarity with or without the use of systemic antibiotics. In patients whose initial visual acuity was hand motions or better, there was no difference in visual outcome whether or not an immediate VIT was performed. However, in the subgroup of patients with initial light perception-only vision, VIT produced a threefold increase in the frequency of achieving 20/40 or better acuity (33% vs 11%), approximately a twofold chance of achieving 20/100 or better acuity (56% vs 30%), and a 50% decrease in the frequency of severe visual loss (20% vs 47%) over TAP. In this group of patients, the difference between VIT and TAP was statistically significant (P < .001, log rank test for cumulative visual acuity scores) over the entire range of vision.Conclusions: Omission of systemic antibiotic treatment can reduce toxic effects, costs, and length of hospital stay. Routine immediate VIT is nor necessary in patients with better than light perception vision at presentation but is of substantial benefit for those who have light perception-only vision.

A 10-year-old boy had a slowly enlarging left limbal mass, extending into the corneal stroma, but not into the anterior chamber. The lesion was excised by lamellar sclerokeratectomy and subsequently confirmed histopathologically as a juvenile xanthogranuloma. Though rare, juvenile xanthogranuloma of the corneoscleral limbus should be considered in the differential diagnosis of limbal mass lesions extending into the cornea. Total resection is usually curative.

A retrospective review was undertaken to compare outcomes in 26 eyes that underwent penetrating keratoplasty (PKP) and drainage tube surgery (Molteno double-plate implant or Schocket procedure). Drainage tube surgery was performed either before PKP (10 eyes), after PKP (7 eyes), or at the same time as PKP (9 eyes). Mean follow up was 22 months. The average preoperative intraocular pressure (IOP) for all of the eyes was 31 mm Hg; 96% of them achieved a final IOP of less than 18 mm Hg (average, 14 mm Hg on a mean of 0.8 medications). Graft failure occurred in 11/26 (42%). Eight of these eyes were regrafted, and six of these eight have remained clear at a mean follow up of 22 months after regrafting. The overall PKP success rate, including the eyes that underwent repeat PKP, was 81%. Visual acuity remained stable or improved in 70% of the eyes.

Purpose: To determine the anatomic and visual results of therapeutic penetrating keratoplasty (PK) and its role in the management of corneal disease.Methods: The authors reviewed the records of all of their patients who had undergone therapeutic PK over the past 9 years and evaluated each for the following criteria: cure of disease, graft clarity, and visual acuity. Patients were divided into seven categories: (1 and 2) bacterial and fungal keratitis, (3 and 4) herpetic keratitis, with and without inflammation, (5) acanthamoebic keratitis, (6) perforations due to keratoconjunctivitis sicca, and (7) other causes of perforation.Results: In microbial keratitis, therapeutic PK eradicated the disease in all cases. Seventy-three percent of grafts for bacterial keratitis and 60% for fungal keratitis remained clear. A higher percentage of clarity was achieved when grafts were 9.0 mm or less. Seven patients with secondary endophthalmitis were cured with a surgical approach including therapeutic PK. In herpetic keratitis with active inflammation, only 36% of grafts remained clear, and inflammation recurred in 36%. All perforations due to postherpetic persistent epithelial defects in ''quiet'' eyes were grafted successfully. In patients with severe keratoconjunctivitis sicca, eyes were anatomically stabilized in 83%, but all grafts failed because of complications from ocular surface disease.Conclusions: Therapeutic PK is valuable in the management of microbial keratitis that does not respond to antimicrobial therapy. Results are poorer for patients with herpetic keratitis, although selected patients respond to therapeutic PK when other methods of management have failed. Patients with perforations due to keratoconjunctivitis sicca have a uniformly poor prognosis for graft clarity.

Ninety-two nonglaucomatous patients undergoing extracapsular cataract extraction with implantation of a posterior chamber intraocular lens by residents at a Veterans hospital were randomized in double-masked fashion to receive either a topical nonsteroidal antiinflammatory agent, diclofenac sodium 0.1%, or a placebo consisting of vehicle only. One drop of placebo or diclofenac sodium 0.1% was administered on an inpatient basis by trained staff every 6 hours for three doses, starting the afternoon prior to surgery. A further drop was given at 90, 60, 30, and 15 minutes before the operation. Starting 24 hours after surgery, all patients received diclofenac sodium 0.1%. All patients remained hospitalized for 72 hours postoperatively. Mean baseline intraocular pressure (IOP) was 14.0 and 14.1 mm Hg in the diclofenac and placebo groups, respectively. IOP rose 8.6 mm Hg in both groups at 6 hours after surgery. At 24 hours, the mean IOP elevation from baseline was 11.3 mm Hg in the diclofenac group and 9.6 mm Hg in the placebo group (P = .47). Within the first 24 hours, IOP spiked more than 10 mm Hg in 57% (26/46) of the diclofenac patients and in 54% (25/46) of the placebo patients. These results suggest that diclofenac sodium 0.1% drops affect neither the incidence nor the height of IOP elevation following cataract surgery.

We reviewed the medical records of 97 patients who had 101 consecutive intraocular lens (IOL) explantation procedures, with or without exchange, at the University of Florida Eye Center from January 1, 1983, to December 31, 1987. The majority of the removed IOLs were anterior chamber styles (53.9%), followed by iris-fixated lenses (33.7%). The most common indications for surgery included pseudophakic bullous keratopathy (PBK)--69%, uveitis-glaucoma-hyphema (UGH) syndrome--9%, and IOL instability--7%. The best visual outcome was seen in patients with IOL instability; 50% achieved 20/40 or better visual acuity. Forty one percent of patients with PBK, who had IOL explantation/exchange combined with penetrating keratoplasty, achieved 20/40 or better visual acuity. The poorest visual outcome was seen in patients with the UGH syndrome; 83% had a final acuity of 20/200 or worse. However, these patients achieved resolution of their pain and inflammation and better control of their intraocular pressure as a result of the surgery. Complications leading to IOL explantation tended to occur months to years after the original surgery in patients with closed-loop, semi-flexible anterior chamber lenses and iris-fixated lenses. Posterior chamber lenses were most often removed because of complications unrelated to the implant.

We treated five patients for postoperative endophthalmitis who demonstrated an initially good response to intravitreal management of their infection and then suffered a later recurrence. Four of the five patients received a single intravitreal injection of antibiotics as the only intravitreal therapy, and the fifth patient received a single antibiotic injection in addition to a partial vitrectomy. All recurrent infections occurred between 10 and 21 days after the original intravitreal injection of antibiotics. At the time of the recurrence, all five patients remained culture positive with the same organism that was initially isolated. The bacterial species isolated were S. epidermidis, group D streptococcus, P. acnes, P. mirabilis, and P. aeruginosa. All patients were ultimately sterilized with repeated intravitreal injections of antibiotics, vitrectomy, and/or intraocular lens removal. Factors that were related to recurrent infection were marginal susceptibility of the organism to the originally injected antibiotics, infection with a slowly replicating organism, and infection with a gram-negative bacillus. A single intravitreal injection of antibiotics may only partially treat bacterial endophthalmitis. Patients should be observed for at least 3 weeks following treatment of endophthalmitis for recurrence of their infection, and aggressive management, including vitrectomy and repeated intravitreal injections of antibiotics, should be used to treat recurrent infections.
