Clinical profile and treatment outcomes of Fusarium keratitis

Purpose: To determine the seasonality, clinical profile, and treatment outcome of Fusarium keratitis. Methods: A retrospective medical chart review of 97 patients with culture?proven Fusarium keratitis at a tertiary eye care institution from January 2018 to December 2019. Results: The median (SD) age at enrollment was 44.6 (16) years; 75 (79.8%) of them were male. Presence of infiltrate less than 4 mm2 at baseline indicated 4.4 times the odds of achieving final BCVA more than 20/60 (95% CI: 1.4–13.3; P = 0.008). The absence of surgical management indicated 8.1 times the odds of achieving final BCVA of more than 20/60 (95% CI: 0.9–71.5; P = 0.06). The visual acuity at presentation, duration between symptoms and presentation, history of ocular trauma, previous use of topical medications, and presence of hypopyon were not identified as significant predictors of final BCVA in the multivariable regression analysis. Conclusion: Smaller infiltrate size and absence of surgical management are the significant predictors of good visual outcome. Visual outcome of Fusarium keratitis is poor, and a significant number of patients did not respond to anti?fungal therapy and had to undergo surgeries. To the best of our knowledge, this is the largest case series on Fusarium keratitis to date

Anterior Uveitis Caused by Listeria Monocytogenes Infection

PURPOSE: To report a case of anterior uveitis secondary to Listeria monocytogenes infection. CASE SUMMARY: A 57-year-old male presented to our clinic with ocular pain and decreased vision in the right eye for 2 days. The patient had a history of liver transplantation 2 years prior and used immunosuppressive agents. Listeria monocytogenes was identified in blood cultures 1 month before his visit. At presentation, best-corrected visual acuity (BCVA) of the right eye was counting fingers at 20 cm and the intraocular pressure (IOP) was 50 mmHg. Conjunctival hyperemia, corneal edema, keratic precipitates, and cells in the anterior chamber were observed in the right eye. The patient was diagnosed as anterior uveitis in the right eye. Conventional uveitis treatment was initiated but clinical features did not improve and black hypopyon appeared. The possibility of anterior uveitis caused by Listeria monocytogenes infection was considered. An anterior chamber tap and culture were conducted to identify pathogens. Anterior chamber antibiotic injections and systemic antibiotic injections were performed. One week after injection, the BCVA of the right eye improved to 0.4 and the IOP decreased to 14 mmHg. One month after injection, the BCVA of the right eye improved to 1.0 and the IOP decreased to 16 mmHg. No inflammation of the anterior chamber was observed. CONCLUSIONS: When nonspecific uveitis occurs in immunosuppressed patients, cultures and appropriate antibiotics should be considered because of the possibility of infection.

Presumably contaminated intravenous infusion-induced Aspergillus terreus endogenous endophthalmitis presenting with posterior hypopyon

A 36-year-old immunocompetent man developed endogenous endophthalmitis 1 week after intravenous fluid infusion in a rural setting. Large submacular abscess with posterior hypopyon warranted urgent vitrectomy which revealed Aspergillus terreus on fungal culture. Intravitreal and oral antifungals lead to resolution of inflammation with satisfactory anatomic outcome but poor visual outcome due to submacular scar.

Presumptive Diagnosis of Recurrent Herpes-induced Anterior Uveitis with Acute Hypopyon

PURPOSE: We report an unusual case of presumptive diagnosis of herpes-induced anterior uveitis with acute hypopyon after trauma. CASE SUMMARY: A 82-year-old male was diagnosed with herpes keratitis due to dendritic keratitis in the left eye, and the lesion disappeared after antiviral treatment. However, 1 year later, the patient visited again with visual loss, pain, and tearing of the left eye after trauma. At the examination, best-corrected visual acuity was counting fingers and the intraocular pressure was 27 mmHg in the left eye. Slit-lamp examination revealed corneal epithelial erosion, moderate corneal edema, and prominent inflammation with 2 mm high hypopyon in the anterior chamber. We thought that bacterial endophthalmitis had rapidly progressed after trauma, so we performed bacterial cultures and an intravitreal antibiotics injection. Considering the clinical manifestations of lesions and herpes keratitis in the past, we could not exclude herpes virus infection. Cultures were negative and the symptoms improved, so the antiviral treatment was gradually reduced and stopped at 2 months. However, recurrence was observed on day 5 after stopping antiviral therapy. We therefore assumed that recurrent herpes virus caused anterior uveitis, and then, antiviral and steroid therapy was resumed. The patient subsequently showed improvement in his symptoms and recovered his visual acuity. CONCLUSIONS: When acute hypopyon is observed in the anterior chamber after trauma, not only bacterial iritis and endophthalmitis but also viral-induced anterior uveitis should be considered in the differential diagnosis.

An Unusual Case of Endogenous Klebsiella Pneumonia Endophthalmitis

PURPOSE: To report an unusual case of endogenous endophthalmitis in a patient with Klebsiella pneumoniae primary liver abscess. CASE SUMMARY: A-54-year-old man with diabetes mellitus and liver abscess was referred to us for consultation of visual loss in his left eye for 2 days. On the first examination, the patient's left visual acuity was hand motion and the left intraocular pressure was 13 mmHg. Vitreous opacity and inflammatory membrane were detected with increased echogenicity using ultrasonography. Vitectomy and intravitreous antibiotic injection were performed under the impression of endogenous endophthalmitis caused by liver abscess on the day of the first visit. Culture revealed Klebsiella pneumoniae from blood and liver abscess. After vitrectomy, the patient showed improvement. However, on the 20th and 40th postoperative days, the patient complained of blurred vision, and inflammation and hypopyon were observed in the anterior chamber. An intracameral antibiotic injection and anterior chamber washing were performed. The patient has not complained of any other symptoms to date. CONCLUSIONS: In this patient with endophthalmitis, inflammation and hypopyon in the anterior chamber were evident three times after vitrectomy. Ultimately, the inflammation was effectively controlled by intracameral antibiotic injection and anterior chamber washes.

Bilateral disciform keratitis in Reiter’s syndrome.

Reiter’s syndrome is commonly associated with conjunctivitis and rarely with uveitis. Bilateral disciform keratitis at presentation is a very rare manifestation in Reiter’s syndrome. A 13-year-old boy developed bilateral disciform keratitis with oligoarthritis following an episode of conjunctivitis. In addition he had suspected bacterial keratitis with hypopyon in the left eye as a possible secondary infection of an epithelial defect that is a feature of Reiter’s keratitis. Empirical treatment with intensive topical antibiotics as a therapeutic trial completely resolved the hypopyon and the disciform keratitis settled with topical steroid treatment. The patient achieved a best corrected vision of 20/20 in both the eyes 6 weeks after the treatment. Bilateral disciform keratitis can occur as a complication of Reiter’s syndrome. Also the possibility of secondary infection of the epithelial defect needs to be borne in mind.

A Case of Acute Anterior Uveitis Associated with HLA-B27 Positivity after Intravitreal Injection of Bevacizumab

PURPOSE: Intravitreal injection of bevacizumab (Avastin(R)) can lead to several intraocular complications including endophthalmitis, hemorrhage and inflammation. We present one case of acute anterior uveitis with hypopyon in an HLA-B27(+) patient following intravitreal injection of bevacizumab. CASE SUMMARY: A 40-year-old male with known central retinal vein occlusion presented with redness and decreased visual acuity in the left eye. Symptoms had developed 4 days earlier after the sixth intravitreal injection of bevacizumab in that eye. The patient had a marked anterior chamber reaction with hypopyon and posterior synechiae. Nine days after onset, similar symptoms in the left eye occurred in the uninjected right eye. Through examination and clinical manifestations, we diagnosed acute anterior uveitis associated with HLA-B27 positivity. The patient was treated with 1% prednisolone acetate, 0.5% moxifloxacin and 1% atropine in both eyes and all symptoms had resolved after 6 weeks.

Relapsing acute myeloid leukemia presenting as hypopyon uveitis.

Anterior segment infiltration in acute myeloid leukemia (AML) presenting as hypopyon uveitis is very rare. We report this case as an uncommon presentation in a patient on remission after bone marrow transplant for AML. In addition to the hypopyon, the patient presented with “red eye” caused by ocular surface disease due to concurrent graft-versus-host disease and glaucoma. The classical manifestations of masquerade syndrome due to AML were altered by concurrent pathologies. Media opacities further confounded the differential diagnosis. We highlight the investigations used to arrive at a definitive diagnosis. In uveitis, there is a need to maintain a high index of clinical suspicion, as early diagnosis in ocular malignancy can save sight and life.

Doença de Behçet / Behçet's disease

A síndrome de Behçet é uma desordem multissistêmica inflamatória crônica caracterizada por uma vasculitede vasos de grande (artéria pulmonar), médio (artérias cerebrais, veias superficiais) e pequeno calibre. Possui distribuição geográfica heterogênea, não sendo rara nos países do Mediterrâneo e no Japão, contrapondo-se à ínfima prevalência no norte da Europa e nas Américas. Não tem predileção por sexo, sendo a idade médio de início em torno de 20 a 35 anos; não se conhece a taxa de incidência anual. A etiologia e a patogenia continuam obscuras. Contudo, estão envolvidos fenômenos imunológicos, demonstrados pela presença de anticorpos contra células endoteliais a e mucosa oral. Dentre os possíveis fatores etiológicos ambientais, cita-se o Streptococcus sanguis, HSV-1, proteína de choque térmico bacteriana de 65kd. Parece haver ainda um componente genético, pois em certas populações há marcante relação entre o HLA-B51 e a doença. Possui características histopatológicas de vasculite, sem especificidade, sendo diagnosticada clínicamente, de acordo com os critérios elaborados pelo Grupo Internacional de Estudos para Síndrome de Behçet. Cursa com manifestações mucocutâneas, com típicas exacerbações e recorrências, além de acometimento do SNC, TGI, musculoesquelético e, sobretudo, ocular. Sintomas inespecíficos, como cansaço, perda de peso e febre baixa, também estão presentes. Devem ser considerados no diagnóstico diferencial: doença de Crohn, Stevens-Johnson, Reiter, pênfigos, líquen plano, mielodisplasias e Aids. No que concerne ao tratamento observam-se dúvidas e desafios, seja pelo curso irregular, ora benigno, ora grave, seja pela polissintomatologia, que requer tratamentos distintos, ou pelo fato de que os muitos esquemas terapêuticos utilizados carecem de indicações precisas; pode-se lançar mão de corticoides tópicos e sistêmicos, imunossupressores, talidomida, metotrexato, colchicina, dentre outros.

Behçet’s disease is a chronic multissistemic inflammatory disorder, characterized by a vasculitides of large (pulmonary artery), medium (cerebral arteries, superficial veins) and small-calibre vases. It has a heterogeneous geographic distribution, not being occasional in Mediterranean countries and in Japan, which is the opposite of the undermost prevalence in North Europe and in the Americas. The illness doesn’t present a sex predilection, and the medium starting age is about 20 to 35 years old, the annual incidence rate is not known. The etiology and pathogeny are still obscure; however, immunologic phenomenons are involved, being demonstrated by the presence of antibodies against endothelial cells and oral mucosa; among the possible etiologic factors, can be mentioned the Streptococcus sanguis, HSV-1 and thermic shock bacterial protein of 65kd. The existence of a genetic component is probable, because there is a marking connection in some populations with HLA-B51 and the disease. Is owns histopathologic characteristics of vasculitides without specification, being clinical diagnose according to the criterions developed by International Studying Group for Behçet’s Disease. The syndrome course presents mucocutaneous manifestation, with typical exacerbations and recurrences, beyond central nervous system, gastrointestinal tract, musculoskeletal and above all, ocular compromising. Inespecific symptoms, as tiredness, weight loss and small fever are also present. Must be considered in the differential diagnose: Crohn disease, Stevens-Johnson, Reiter, pemphigus, plane lichen, mielodisplasias and Aids. Concerning the treatment, doubts and challenges are observed, considering the irregular course of the disease, sometimes benign, and sometimes grave; besides the multiple symptoms, which request distinct treatments, or for the fact that the multiple therapeutic schemes used lacks exact indications, being mostly based in personal self opinions and experiences...

A Case of Hypopyon Uveitis Associated With Relapsing Polychondritis

PURPOSE: Relapsing polychondritis is an uncommon systemic autoimmune disorder which is characterized by recurrent and often progressive inflammatory episodes involving multiple organ systems, including the ophthalmic, otorhinolaryngeal, respiratory, musculoskeletal, renal, cardiovascular, and dermatologic systems. The most common ocular manifestations are episcleritis and scleritis. Uveitis, especially the nongranulomatous type, has been reported in 3% to 22% of relapsing polychondritis cases. We report uncommon hypopyon uveitis as an ophthalmic finding associated with relapsing polychondritis. CASE SUMMARY: A 56-year-old woman with known relapsing polychondritis presented with ocular pain and redness in the right eye which had developed two months before and was managed for scleritis. However, she developed blurred vision, and hypopyon and vitreous opacity was found. The patient presented to our clinic and we diagnosed her with hypopyon uveitis associated with relapsing polychondritis. The patient was started on systemic steroid therapy consisting of 1% prednisolone acetate, 0.5% moxifloxacin, and 0.5% tobramycin in the right eye. Hypopyon disappeared 8 days following the initiation of treatment, and all symptoms had resolved after 14 days.

Clinical Manifestations of Presumed Sterile Endophthalmitis After Intravitreal Triamcinolone Injection

PURPOSE: To evaluate the distinguishing characteristics that may assist in the clinical diagnosis of sterile endophthalmitis from intravitreal triamcinolone injection. METHODS: From January 2005 to June 2006, the medical records of 163 eyes that received intravitreal triamcinolone injection were reviewed. In 5 eyes of 5 patients who complained of decreasing vision and mild ocular pain within three days after injection, slit lamp bimicroscopy revealed hypopyon, anterior chamber reaction, and vitritis. We analyzed clinical pictures retrospectively. RESULTS: Intravitreal triamcinolone injections were performed for diabetic macular edema in 4 patients and for panuveitis in 1 patient with Behcet's disease. Pseudophakia was found in all five eyes. Inflammations in three eyes resolved with topical and oral antibiotics within 13 days, and the other two patients were treated with a vitreous culture and intravitreal antibiotic injection. However, vitreous tap showed no evidence of endophthalmitis, and inflammation resolved within the same period. CONCLUSIONS: Presumed sterile endophthalmitis presents within 3 days after intravitreal triamcinolone injection and may be accompanied by decreased vision and ocular discomfort, although it is characterized by no distinct ocular pain. The symptoms and ocular inflammation resolved quickly within 13 days with a favorable visual outcome. Inflammations in three eyes resolved without surgical intervention, so it may be necessary to closely observe clinical manifestations before assuming that the eye is suffering from infectious endophthalmitis.

Intravitreal Thrombin Injection for Control of Hemorrhage During the Vitreous Surgery

Intraocular hemorrhage is a major problem during the vitreous surgery, despite of improvements in instrumentation and operative methods. Infusion of thrombin has been reported as an efficacious method of control of intraocular hemorrhage in various vitreous surgery. In this study, 100 U/ml diluted thrombin was injected through the infusion system of Grieshaber manipulator into the vitrous cavity on the bleeding site instead of adding to the infusion solution in 10 cases of vitreous surgery including proliferative diabetic retinopathy, posttraumatic advanced proliferative vitreoretinopathy and giant retinal tear. As the result, all cases of intraocular hemorrhage were controlled within 2 min utes after the injection of thrombin, with the combined use of intraocular diathermy or elevation of intraoclar pressure. The amount of diluted thrombin which was injected in concentration of 100 U/ml, was less than 5ml. The 6 cases of postop erative complication were noted, including 2 cases of vitreous hemorrhage and 4 cases of hypopyon which were controlled within 5 days with topical steroid therapy.
