RESUMEN
PURPOSE: The purpose of the study was to describe the vitreal, retinal, and choroidal features of eyes affected by endogenous endophthalmitis (EE) and evaluate the effects of systemic antifungal drug treatment and pars plana vitrectomy by using spectral domain optical coherence tomography (SD-OCT). METHODS: Medical records and SD-OCT images of eyes diagnosed with EE at a single uveitis tertiary referral center in Brazil were acquired at the time of diagnosis, after 7 days of high-dose antifungal drug treatment, and at follow-up assessments performed 30 days after resolution. RESULTS: Thirteen eyes were enrolled in the study. All patients showed hyperreflective round-shaped lesions on SD-OCT and pre-retinal aggregates. Five eyes responded to antifungal systemic oral drugs despite showing vitreous opacity. The response to treatment was observable on optical coherence tomography (OCT) images. CONCLUSION: Fungal endophthalmitis showed typical features on SD-OCT, facilitating early diagnosis and treatment despite the absence of vitreous culture or biopsy. This study suggests that OCT images can be used to support diagnosis by physicians who do not have access to vitreoretinal surgery.

Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (< 13 years of age) and one patient was an adult. Two patients reported contact with a cat that had sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.

Human monkeypox is a zoonosis caused by an orthopoxvirus and the clinical presentation resembles that of smallpox and chickenpox. The disease may start with a prodrome that includes lymphadenopathy, headache, fatigue, and fever, followed by a vesiculo-pustular rash. Ocular manifestations such as conjunctivitis and edema are present in approximately 20% of affected people, with a greater incidence among unvaccinated patients. Corneal involvement has also been reported and can result in corneal scarring and severe forms of keratitis. The natural course of the disease is most often benign and self-limiting, however, in some individuals, especially immunocompromised patients, there is a risk of complications such as bronchopneumonia, encephalitis, and vision loss. Herein, we present a case of a patient with monkeypox which caused conjunctival vesicles and anterior uveitis.

Bilateral acute depigmentation of the iris and bilateral acute iris transillumination (BAIT) are similar clinical entities. The former causes acute-onset depigmentation of the iris stroma without transillumination, whereas the latter causes depigmentation of the iris pigment epithelium with transillumination. The etiopathogenesis of these conditions is not yet fully understood, but the proposed causes include the use of systemic antibiotics (especially moxifloxacin) and viral triggers. We present a case series of five female patients with a mean age of 41 (32-45) years, all of whom suffered acute onset of bilateral pain and redness of the eyes after moxifloxacin use (oral or topical). It is important for ophthalmologists to be aware of the two forms of iris depigmentation since this case series suggests that SARS-CoV-2 or its empirical treatment with moxifloxacin may trigger iris depigmentation. If this is the case, clinicians will likely see increased incidences of bilateral acute depigmentation of the iris and bilateral acute iris transillumination during and after the COVID-19 pandemic.

This retrospective case series aims to describe the ophthalmic manifestations of the Monkeypox virus infection in seven patients evaluated in two countries of South America (Colombia and Brazil). Two had skin lesions in the eyelid, and five had conjunctivitis. None had intraocular involvement. Three of seven patients had a history of Human Immunodeficiency Virus infection, and all patients had lesions in the genital region, suggesting sexual-contact transmission. In 6 of 7 cases, conjunctival RT-PCR was positive for the Monkeypox virus, including one case without conjunctival vesicles. In all cases, lesions resolved without complications, and just two required antiviral treatment. All patients demonstrated improvement without complications. RT-PCR positivity in conjunctiva demonstrated the presence of the Monkeypox virus, suggesting that ocular-mediated transmission could be plausible. Ophthalmologists should be aware of this ophthalmic manifestation.

Sympathetic ophthalmia is a rare and potentially devastating bilateral diffuse granulomatous panuveitis. It is caused by surgical or non-surgical eye injuries and is an uncommon and serious complication of trauma. It is diagnosed clinically and supported by imaging examinations such as ocular ultrasonography and optical coherence tomography. Its treatment consists of immunosuppressive therapy with steroids and sometimes steroid-sparing drugs, such as cyclosporine, azathioprine, cyclophosphamide, and mycophenolate mofetil. Fast and effective management with systemic immunosuppressive agents allows for disease control and achievement of good visual acuity in the sympathizing eye. By contrast, enucleation should be considered only in situations where the injured eye has no light perception or in the presence of severe trauma. In addition to a bibliographic review of this topic, we report six cases involving different immunosuppressive and surgical treatment modalities.

PURPOSE: To describe the most important cause of infectious posterior uveitis in pediatric patients. METHODS: Review of the literature. RESULTS: The most important causes of infectious uveitis in pediatric patients are: cat-scratch disease, toxocariasis, tuberculosis, viral diseases and toxoplasmosis. Ocular manifestations include retinitis, neuroretinitis, choroidal granulomas, peripheral granulomas and posterior pole granulomas. CONCLUSION: Infectious posterior uveitis is a challenging subject and should be considered in the differential diagnosis of any posterior uveitis in children. Infectious uveitis must be excluded before initiating immunosuppressive therapy.

INTRODUCTION: Ampiginous Choroiditis is a rare posterior uveitis that combines clinical features of Acute Multifocal Posterior Placoid Pigment Epitheliopathy and Serpiginous Chorioretinitis. Its pathophysiology is poorly understood and further studies are necessary to understand which mechanisms start the immunologic reaction. CASE REPORT: The purpose of this article is to report a well-documented case of Ampiginous Choroiditis following in seven days a RT-PCR confirmed SARS-CoV-2 infection, suggesting that the infection might have contributed as a trigger. CONCLUSION: Timely diagnosis and correct treatment are paramount to improve the visual outcomes, and the patient had successful response to systemic steroids.

PURPOSE: The aim of this article is to do a comprehensive literature review about the current role of pars plana vitrectomy in uveitis and in its different structural complications such as cystoid macular edema, epiretinal membrane, macular hole, and retinal detachment. METHODS: This comprehensive literature review was performed based on a search on PubMed, BioMed Central, Science Open, and CORE databases, of relevant articles abording pars plana vitrectomy in uveitis. DISCUSSION: Uveitis is a complex disease with multiple etiologies and pathogenic mechanisms. Therapeutic pars plana vitrectomy (PPV) may aid in uveitic structural complications such as cystoid macular edema, epiretinal membranes, macular hole, and retinal detachments even though some cases may present unpredictable visual outcomes. Diagnostic PPV with appropriate ancillary testing is also a valuable tool for the assessment and diagnosis of uveitis in a large proportion of patients. CONCLUSION: Over the years, pars plana vitrectomy has undergone significant transformations since its invention nearly 5 decades ago, however, the quality of evidence in the literature regarding its use for uveitis has not improved in the same way. Even though some structural uveitis complications (as previously mentioned) may respond well to surgery, there is still a certain unpredictability regarding its visual outcomes. On the other hand, diagnostic vitrectomy with appropriate ancillary testing is also a valuable tool for the assessment and diagnosis of uveitis in a large proportion of patients.
RESUMEN
PURPOSE: To describe the clinical characteristics, severity, and ophthalmological changes in SARS-CoV-2 patients through ophthalmological examinations performed at the reference center of the National Institute of Infectious Diseases, Brazil. METHODS: This cross-sectional study assessed the examination results of SARS-CoV-2 patients from July 2020 to November 2020. In total, 150 patients were included and allocated into three groups of 50 patients depending on the disease severity. Group 1 patients were in the intensive care unit (ICU), group 2 patients were in the semi-ICU, and group 3 patients were outpatients. RESULTS: Ten (6.7%) patients exhibited ophthalmological changes; five (10%), four (8%), and one (2%) patients in groups 1, 2, and 3, respectively. Ophthalmological findings included candle flame hemorrhage and cotton wool exudates. We analyzed the general characteristics of the 10 patients with ophthalmological changes. Nine were hospitalized and one was seen on an outpatient basis. CONCLUSION: We observed ophthalmic changes in patients with SARS-CoV-2 infection, despite the absence of any clinical or laboratory risk factors indicative of such changes.

INTRODUCTION: Ocular toxoplasmosis is the leading cause of posterior uveitis worldwide, affecting individuals acrossdifferent age groups. The key to reducing vision loss includes prompt diagnosis and treatment. However, despite the prevalence of ocular toxoplasmosis, there has been little consensus regarding its pathophysiology,clinical features, diagnosis, and especially management. METHODS: The data sources were literature reviews, including Pub Med and Medline databases. Search terms included toxoplasmosis, retinitis, vasculitis, vitritis, uveitis alone or in combination with, serum, aqueous, vitreous eye, ocular and review. RESULTS: In this review paper, we have sought to provide an overview of the pathophysiology, epidemiology, and clinical features of the disease, both based on current literature and our own clinical experience. We have also discussed the use of serology, ocular fluid, and ophthalmic investigations that could further facilitate the diagnosis of ocular toxoplasmosis.Different management strategies have been reported worldwide, including newer approaches such as local therapy. CONCLUSION: A better understanding of critical aspects of ocular toxoplasmosis will hopefully lead to reduced morbidity, including blindness associated with this condition.

PURPOSE: To describe and illustrate the main optical coherence tomography (OCT) findings of infectious uveitis. METHODS: Narrative review. RESULTS: Posterior segment OCT in patients with infectious uveitis reveals posterior hyaloid face precipitates, superficial retinal precipitates and infiltrates, foveolitis, retinitis, neuro-retinitis, choroidal granulomas, and choroiditis as main imaging biomarkers. Some of these features are specific to the underlying causing etiology and may support the diagnosis and the initiation of treatment. Some OCT features disappear completely with resolution; some others are associated with irreversible retinal damage. CONCLUSIONS: OCT identifies different features of infectious uveitis into the vitreous, the retina, and the choroid. OCT characteristics, combined with other multimodal imaging features, are helpful in the differential diagnosis of infectious uveitis, the early detection of complications, and the assessment of the response to therapy.

Although rare, disseminated sporotrichosis is increasing in several countries. Despite its limiting toxic potential, amphotericin B is the only intravenous antifungal available to treat severe sporotrichosis. We aimed to describe the effectiveness and safety of amphotericin B treatment for severe sporotrichosis. Clinical records of patients with disseminated sporotrichosis at a reference center were reviewed. This study included 73 patients. Most (53.4%) were men and non-white. HIV coinfection was the main comorbidity (52.1%). Most reported contact with cats (76.7%). Sporothrix brasiliensis was the causative species. Affected sites were skin (98.6%), osteoarticular system (64.4%), upper airway (42.5%), central nervous system (20.5%), eyes (12.3%), and lungs (8.2%). Median doses of amphotericin B used were 750 mg and 4500 mg for deoxycholate and lipid complex formulations, respectively. Amphotericin B discontinuation occurred in 20.5% due to adverse events, mainly azotemia. The outcomes included cure (52.1%), death due to sporotrichosis (21.9%), death due to other causes (9.6%), and loss to follow-up (8.2%). Survival analysis showed an association between cure and the absence of bone, upper airway, and central nervous system involvement. Amphotericin B is the first-choice treatment for disseminated sporotrichosis; however, the severity of systemic dissemination might predict its response. Favorable clinical results depend on prompt diagnosis, investigation of fungal dissemination, and early therapy initiation.
RESUMEN
UNLABELLED: Itraconazole is currently used for the treatment of cutaneous sporotrichosis. Terbinafine at a daily dose of 250 mg has been successfully applied to the treatment of cutaneous sporotrichosis. OBJECTIVE: To compare the efficacy of 250 mg/day terbinafine and 100 mg/day itraconazole for the treatment of cutaneous sporotrichosis. MATERIALS AND METHODS: A bidirectional cohort study was conducted on 55 patients receiving 250 mg/day terbinafine and 249 patients receiving 100 mg/day itraconazole. The latter patients were matched for age and clinical form to the terbinafine group at a ratio of 5:1. Sporothrix schenckii was isolated by culture from all patients (age range: 18-70 years), who were submitted to the standard care protocol consisting of clinical and laboratory evaluation and periodic visits. RESULTS: Cure was observed in 51 (92.7%) patients of the terbinafine group and 229 (92%) of the itraconazole group within a similar mean period of time (11.5 and 11.8 weeks, respectively). An increase in the terbinafine dose to 500 mg was necessary in two patients due to the lack of a response, and one patient presented recurrence. In the itraconazole group, two patients required a dose increase and three presented recurrence. Adverse events were equally frequent among patients receiving terbinafine (n = 4, 7.3%) and itraconazole (n = 19, 7.6%) and were generally mild without the need for drug discontinuation, except for two patients of the itraconazole group. CONCLUSION: Terbinafine administered at a daily dose of 250 mg is an effective and well-tolerated option for the treatment of cutaneous sporotrichosis.

Purpose: To describe a case of presumed ocular toxoplasmosis.Method: A retrospective chart review.Result: This case report describes a 35-year-old male who presented hypopyon anterior uveitis in his left eye. Fundus examination revealed severe vitritis which precluded the view of retina. His serum anti-toxoplasma immunoglobulin (Ig)G was significantly raised, with a normal anti-toxoplasma IgM level and PCR from nested primers targeting B1 gene of Toxoplasma gondii was positive. He was started on empirical anti-toxoplasma therapy. Undiluted vitreous specimen collected during lensectomy and diagnostic vitrectomy in left eye was also positive for nested primers targeting B1 gene of T. gondii.Conclusion: Ocular toxoplasmosis without retinochoroiditis, though extremely rare, can occur.

DUSN is an infectious ocular disease that can lead to severe visual impairment and blindness. It usually occurs in young healthy individuals and depending on the stage of the disease, clinical presentation may range from mild vitritis and multifocal gray-white lesions in outer retina to optic atrophy.Parasites of different sizes and species have been proposed as the etiological agent of this disease. Thus, it is hypothesized that different infectious worms may be considered as the likely cause of a both autoimmune and toxic form of nematode retinopathy.Most patients present with already severe visual impairment and in the later stages of the disease, where the likelihood of improvement is low, despite therapy. In cases of early diagnosis, prompt treatment, whether with oral antihelmintic or direct photocoagulation of the worm, patients may show considerable visual improvement and have a more favorable prognosis.

PURPOSE: To describe 26 cases of bulbar conjunctival sporotrichosis. METHODS: Review of clinical records of patients with bulbar conjunctivitis due to culture-proven Sporothrix spp. infection, in Rio de Janeiro, from 2007 to 2017. RESULTS: Twenty-six patients were identified. Median age was 25 years. Adults were more affected (53.8%), followed by adolescents (26.9%). There was a predominance of women (73.1%). Twenty-four patients (96%) reported contact with cats with sporotrichosis. Twenty-one patients (80.8%) presented a primary ocular sporotrichosis. Five patients presented associated eyelid lesions, and 21 (80.8%) tarsal conjunctivitis. Parinaud oculoglandular syndrome was observed in 17 (81%) patients. Eight patients (36.4%) reported the use of steroid drops before diagnosis was made. All patients but one were treated with oral itraconazole. Twenty-three patients (88.5%) were completely cured and three (11.5%) were lost to follow-up. Eight patients (34.8%) developed ocular sequelae. CONCLUSION: Bulbar conjunctivitis is an important clinical presentation of ocular sporotrichosis. It can lead to ocular sequelae. Sporotrichosis should be considered in the differential diagnosis of ophthalmic external diseases, especially in patients with cat contact history.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB.
