Bacterial endophthalmitis following anti-VEGF intravitreal injections: a retrospective case series.

BACKGROUND: To describe the incidence of endophthalmitis and the treatment outcomes of acute bacterial endophthalmitis following intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections in a Brazilian hospital. The analysis was based on the timing of infection after intravitreal injection, culture results, visual acuity, and the presence of epiretinal membrane after a 1-year follow-up period, spanning nine years. METHODS: This retrospective case series, conducted over a 9-year period, aimed to evaluate the treatment outcomes of acute endophthalmitis following intravitreal Bevacizumab injections. The inclusion criteria involved a chart review of 25 patients who presented clinical signs of acute endophthalmitis out of a total of 12,441 injections administered between January 2011 and December 2019. Negative culture results of vitreous samples or incomplete data were excluded. Ultimately, 23 patients were enrolled in the study. Eight patients were treated with intravitreal antibiotic injections (IVAI) using vancomycin 1.0 mg/0.05mL and ceftazidime 2.25 mg/0.05mL, while 15 patients underwent pars plana vitrectomy (PPV) followed by intravitreal antibiotic injections at the end of surgery (IVAIES). The main outcome measures were the efficacy of controlling the infection with IVAI as a standalone therapy compared to early PPV followed by IVAIES. Data collected included pre-infection and one-year post-treatment best corrected visual acuity (BCVA), optical coherence tomography (OCT) abnormalities, and enucleation/evisceration rates. To compare groups, Mann-Whitney and ANOVA tests were employed for statistical analysis. RESULTS: The incidence rate of bacterial endophthalmitis was 0.185% (1/541 anti-VEGF injections), with the highest infection rates observed in 2014 and 2017. Patients presented clinical symptoms between 2 and 7 days after injection. The most common isolated organisms were coagulase-negative Staphylococci and Streptococci spp. Treatment outcomes showed that both IVAI and PPV + IVAIES effectively controlled the infection and prevented globe atrophy. After one year, the PPV group with BCVA better than Light Perception had a significantly better BCVA compared to the IVAI group (p 0.003). However, PPV group had higher incidence of epiretinal membranes formation compared to the IVAI group. (P 0.035) CONCLUSION: Anti-VEGF injections carry a risk of developing acute bacterial endophthalmitis. Isolated antibiotic therapy could be an effective treatment to control the infection, but performing PPV + IVAIES as a primary treatment showed promising results in terms of improving BCVA after one year, despite a higher rate of epiretinal membrane formation. Further studies are needed to confirm these findings.

Evisceration and enucleation cases in the ophthalmologic emergency department of a tertiary Brazilian hospital / Casos de evisceração e enucleação em departamento de urgência oftalmológica de um hospital terciário Brasileiro

ABSTRACT Purpose: To analyze the epidemiological profiles of evisceration and enucleation cases in the ophthalmologic emergency department of a Brazilian tertiary hospital. Methods: Patients treated in the ophthalmologic emergency department of Hospital São Paulo (Universidade Federal de São Paulo) during the period 2013 to 2018 were retrospectively evaluated. Urgent cases of evisceration or enucleation surgery were included, and elective cases were excluded. The following information was extracted from the patients' medical records: demographic data, immediate and associated reasons for the surgical procedure, informed visual acuity, symptom duration until ophthalmologic care, complications, distance from the residence to the tertiary hospital, and time of hospitalization. Results: In total, 61 enucleations and 121 eviscerations were included in this study. The patients had a mean age of 63.27 ± 18.68 years. Of the patients, 99 were male (54.40%), and 83 were female (45.60%). The indications for evisceration or enucleation were corneal perforation with (44.50%) and without (23.63%) signs of infection, endophthalmitis (15.38%), ocular trauma (14.29%), neoplasia (0.55%), burn accident (1.10%), and phthisis bulbi (0.55%). The self-reported visual acuity was no light perception (87.36%) or light perception (1.10%). However, 3.30% of the patients did not cooperate with the examination, and no information on visual acuity was available for the remaining 8.24%. The mean symptom duration before ophthalmologic care was sought was 18.32 days. Two patients had sympathetic ophthalmia after evisceration. Conclusions: More eviscerations than enucleations were performed throughout the study period. The most common demographic characteristics were age >60 years and male sex. The main indications for urgent evisceration and enucleation procedures were corneal perforation with and without infection, endophthalmitis, and ocular trauma. The findings from this study could guide clinicians in performing preventive measures to avoid destructive eye procedures.

White dot syndrome in a patient with presumed ocular tuberculosis: a case report.

BACKGROUND: This manuscript describes a case of a patient with presumed ocular tuberculosis masquerading as multiple evanescent white dot syndrome. CASE PRESENTATION: A 32-year-old male patient presented with a complaint of reduced visual acuity in the left eye. Retinal fundus exam of the left eye revealed gray-whitish deep lesions predominantly nasal to the optic disc. The lesions were more clearly identifiable on fundus autofluorescence (FAF) imaging, fluorescein angiography (FA) and en face optical coherence tomography (OCT). FA also indicated retinal vasculitis and papillitis. Swept-source OCT B-scan demonstrated loss of the ellipsoid layer in the regions corresponding to the lesions detected by FAF. A positive tuberculin skin test (TST) confirmed presumed tuberculosis, and a related WDS diagnosis was made. Specific antituberculosis therapy was instituted with favorable anatomical recovery and visual outcome. CONCLUSION: Multiple evanescent white dot syndrome (MEWDS) may be manifestation of presumed ocular tuberculosis, and multimodal retinal exams can provide a better understanding of atypical diseases and their follow-up.

Obstructive sleep apnea and the retina: a review.

CITATION: This review's objective was to synthesize the literature on the repercussions of obstructive sleep apnea (OSA) in the retinal vascular system. Two independent investigators conducted a search using the MEDLINE/PubMed database using the following terms: sleep apnea syndrome, obstructive sleep apnea, retina, vascular tortuosity, central serous chorioretinopathy, diabetes mellitus, and subfoveal choroidal thickness. Patients with OSA present increased vascular tortuosity compared with patients without OSA, decreased parafoveal and peripapillary vessel density, and increased retinal vein occlusion incidence. In central serous chorioretinopathy patients and patients who are poor responders to intravitreal anti-VEGF (-vascular endothelial growth factor) treatment for macular edema, OSA is more frequent. Macular choroidal thickness alterations are controversial, and OSA may worsen diabetic maculopathy, thus being a risk factor for diabetic retinopathy, proliferative diabetic retinopathy, and macular edema. OSA is a prevalent syndrome with many systemic vascular changes. The retina and choroid are the most affected ocular structures, with primarily vascular changes. New noninvasive technologies such as optical coherence tomography and optical coherence tomography angiography could help to better understand retinal structures and help clarify the ophthalmological repercussions of OSA.

Bartonella hanselae retinitis patient evaluated with multimodal retinal exams.

BACKGROUND: Cat scratch disease is a systemic infectious illness caused by the bacterium Bartonella henselae. The most common ophthalmological involvement due to infection by Bartonella is Parinaud oculoglandular syndrome, whereas the most common posterior segment findings are neuroretinitis and subsequent late macular star. Moreover, other findings, such as retinal or subretinal lesions, intermediate uveitis and angiomatous lesions, may be present. CASE PRESENTATION: A 37-year-old female patient with retinal findings and serological confirmation of Bartonella infection was evaluated via multimodal retinal exams. The patient received treatment with doxycycline 100 mg twice daily for 2 weeks. One month after treatment, complete improvement of her visual scotoma symptoms was confirmed. A swept-source optical coherence tomography exam also showed decreases in the size and intraretinal extension of the lesion. Improvement of light perception at the affected area was confirmed by microperimetry. CONCLUSIONS: Bartonella henselae infection, particularly retinitis, can present a variable spectrum of clinical and ophthalmological findings. Multimodal retinal exams can clearly identify lesion characteristics, thus providing important information for diagnosis and the evaluation of lesion improvement after antibiotic treatment.

Role of Vital Dyes in Chromovitrectomy.

ABSTRACT: Chromovitrectomy, the intraocular application of dyes to assist visualization of preretinal tissues during vitreoretinal surgery, was introduced to avoid ocular complications related to internal limiting membrane peeling, inadequate removal of the vitreous, and incomplete removal of epiretinal membranes. Since 2000, chromovitrectomy has become a popular approach among vitreoretinal specialists. The first vital dye used in chromovitrectomy, indocyanine green, facilitated identification of the fine and transparent internal limiting membrane. Following indocyanine green, trypan blue was introduced to identify epiretinal membranes, and triamcinolone acetonide stained the vitreous well. Recently, additional natural dyes such as lutein and anthocyanin from the açaí fruit have been proposed for intraocular application during vitrectomy. The main goal of this review was to study the role of vital stains in chromovitrectomy and report the latest findings in the literature.

Twelve-Year-Old Girl with Acute Macular Neuroretinopathy: A Multimodal Retinal Evaluation.

We report a 12-year-old female patient with acute macular neuroretinopathy assessed with multimodal retinal exams. Initial fluorescein angiogram and optical coherence tomography angiography (OCT-A) were both normal, and after 4 months OCT-A showed abnormal vascular flow with normal flow in superficial retina layers, choroid, and choriocapillaris.

Six-year epidemiological analysis of post traumatic endophthalmitis in a Brazilian hospital.

BACKGROUND: To evaluate the epidemiology of endophthalmitis cases related to ocular trauma, including visual acuity during and 1 year after trauma, source of trauma and method of treatment. METHODS: A retrospective study analyzed the epidemiological data of patients with a clinical presentation of endophthalmitis after ocular penetrating trauma between January 2012 and January 2017 at Escola Paulista de Medicina/UNIFESP, a hospital in São Paulo, SP, Brazil. RESULTS: A total of 453 patients with antecedent open globe trauma were evaluated, among these, 30 patients with suspected endophthalmitis. All patients were male. The time interval between trauma and ophthalmological evaluation and collection of vitreous and aqueous material was 1 day in 36.66%, 2-7 days in 43.44%, 7-14 days in 10% and more than 15 days in 10% of patients; 66.66% had positive cultures. 11 patients had intraocular foreign body. One year after trauma, visual acuity was classified as no light perception (NLP) in 33.33%, light perception in 6.66%, hand motion in 13.33%, counting fingers in 13.33%, and better than 20/400 in 20% of patients. Considering presence of intraocular foreign body, initial visual acuity and symptoms onset time, only initial visual acuity showed as better prognostic factor in final visual acuity. CONCLUSION: Endophthalmitis is a severe ocular inflammatory condition that may lead to irreversible vision loss. Initially only one patient had visual acuity of NLP, but after 1 year, 33% showed visual acuity of NLP, and only 20% had visual acuity better than 20/400, what is consistent with a severe infection with a guarded prognosis. The high incidence of endophthalmitis after ocular penetrant trauma justifies distinct treatment and greater attention.

Factors associated with vision-related quality of life in Brazilian patients with glaucoma / Fatores associados à qualidade de vida relacionada à visão em pacientes brasileiros com glaucoma

ABSTRACT Purpose: To evaluate the impact of visual acuity, visual field damage, and other factors on the quality of life in Brazilian patients with glaucoma. Methods: This cross-sectional prospective study involved 49 patients with glaucoma enrolled based on the presence of reproducible standard automated perimetry defects in at least one eye at the time of evaluation. A detailed ophthalmologic examination was performed on each patient. All patients had reproducible standard automated perimetry and completed an NEI VFQ-25 questionnaire. The associations of the quality of life scores to the best-corrected visual acuity and the visual field loss of the better and worse eyes were investigated. Results: The mean quality of life score of the patients was 58.8 ± 18.7 units. The highest and lowest mean values (85.0 ± 24.2 and 37.5 ± 36.5 units) were observed in the "Social Functioning Subscale" and "Driving Subscale," respectively. Patients with advanced glaucoma (mean deviation <-12 dB) in the worse eye had significantly lower quality of life scores (p=0.007). There was a significant correlation between the quality of life scores and the visual acuity of the better and worse eyes (r2=13%, p=0.010 and r2=32%, p<0.001, respectively). There was also a significant correlation between the quality of life scores and standard automated perimetry mean deviation of the better and worse eyes (r2=13%, p=0.023 and r2=47%, p<0.001, respectively). In a multivariate model containing so­cioeconomic and comorbidity indices, quality of life remained significantly related to the standard automated perimetry mean deviation of the better and worse eyes (r2=23%, p=0.29 and r2=49%, p<0.001, respectively) as well as to the visual acuity of the better and worse eyes (r2=18%, p=0.017 and r2=40%, p<0.001, respectively). Conclusion: The standard automated perimetry mean deviation and the visual acuity of the better and worse eyes were associated with lower quality of life in Brazilian patients with glaucoma. Quality of life was mostly highly associated with the standard automated perimetry mean deviation of the worse eye.

RESUMO Objetivo: Avaliar o impacto da acuidade visual, danos no campo visual e outros fatores na qualidade de vida em pacientes brasileiros com glaucoma. Métodos: Este foi um estudo transversal prospectivo incluindo 49 pacientes com glau­coma selecionados com base na presença de defeitos por perimetria automatizada padrão reprodutíveis em pelo menos um olho no momento da avaliação. Um exame oftalmológico detalhado foi realizado em cada paciente. Todos os pacientes possuíam perimetria automatizada padrão reprodutível e preencheram um questionário NEI VFQ-25. As associações dos escores de qualidade de vida à acuidade visual melhor corrigida e à perda de campo visual dos melhores e piores olhos foram investigadas. Resultados: A média dos escores de qualidade de vida dos pacientes foi de 58,8 ± 18,7 unidades. Os maiores e menores valores médios (85,0 ± 24,2 e 37,5 ± 36,5 unidades) foram observados nas subescalas "Social Functioning Subscale" e "Driving Subscale", respectivamente. Pacientes com glaucoma avançado (desvio médio <-12 dB) no pior olho tiveram escores de qualidade de vida significativamente menores (p=0,007). Houve correlação significativa entre escores de qualidade de vida e a acuidade visual dos olhos melhores e piores (r2=13%; p=0,010 e r2=32%; p<0,001; respectivamente). Houve também uma correlação significativa entre os escores de qualidade de vida e desvios médios da perimetria automatizada padrão dos olhos melhores e piores (r2=13%; p=0,023 e r2=47%; p<0,001; respectivamente). Em um modelo multivariado contendo dados socioeconômicos e de comorbidades, a qualidade de vida permaneceu significativamente relacionada ao desvio médio padrão da perimetria automatizada do olho melhor e pior (r2=23%; p=0,29 e r2=49%; p<0,001, respectivamente) bem como para a acuidade visual do olho melhor e pior (r2=18%; p= 0,017 e r2=40%; p<0,001, respectivamente). Conclusão: O desvio padrão da perimetria automatizada padrão e a acuidade visual dos olhos melhor e pior foram associados à menor qualidade de vida em pacientes brasileiros com glaucoma. A qualidade de vida foi em grande parte altamente associada ao desvio padrão da perimetria automatizada padrão do pior olho.

The retinal foveal avascular zone as a systemic biomarker to evaluate inflammatory bowel disease control.

BACKGROUND: Inflammatory bowel disease (IBD) is a systemic inflammatory disease and is classified as Crohn's disease (CD) or ulcerative colitis (UC) depending on the extent of gastrointestinal tract involvement. IBD can be associated with extraintestinal findings, such as fever, weight loss, arthralgia, and mucocutaneous lesions, as well as hepatic, renal and ophthalmological involvement. Clinical parameters and colonoscopy are used to establish the criteria for controlled or non-controlled disease and subsequent definition of treatment. Our objective in the present study was to compare the area of the foveal avascular zone (FAZ) in patients with a diagnosis of IBD during remission and active disease. METHODS: 144 eyes of 72 patients with IBD were evaluated via a complete ophthalmological exam. Fundus photography and optical coherence tomography/angiography (OCT/OCTA) were performed with a Topcon Triton. The macula and posterior pole were evaluated by binocular indirect ophthalmoscopy and fundus biomicroscopy. The area of the FAZ was determined via manual delimitation of superficial retinal vascular layers from OCTA with image6.net software. To establish disease activity, we considered the Mayo Score, fecal calprotectin levels, colonoscopy results and clinical parameters. All retinal parameters were evaluated in a blinded manner. Means were compared between groups using the Mann-Whitney test. RESULTS: The participants had a mean age of 42.26 years and included 28 males (38.88%) and 44 females (61.11%). Among the participants, 37 had a diagnosis of CD (51.38%), and 35 had a diagnosis of UC (48.61%). Twenty-five patients (34.72%) had active disease, and 47 (65.27%) were in remission. The area of the FAZ did not differ significantly between the CD and UC groups (p = 0.91 for the right eye and p = 0.76 for the left eye) but did differ significantly between the remission and active disease groups (p = 0.01 for the right eye and p = 0.02 for the left eye). DISCUSSION: Our study is the first to evaluate the area of the FAZ in patients with IBD via swept-source OCTA. The area of the FAZ did not differ significantly in either eye between the CD and UC groups. However, patients classified as having active disease according to clinical parameters and colonoscopy presented a significant decrease in the area of the FAZ compared with patients in remission. The area of the FAZ is an ophthalmological parameter that can be obtained non-invasively and is increased in ischemic diseases such as diabetic retinopathy. The FAZ may decrease due to vascular engorgement or increased systemic inflammation. This parameter can be used to help determine whether a patient is in remission or active IBD, thus potentially reducing the need for invasive exams during disease follow-up.

FREQUENCY OF OPHTHALMOLOGICAL POSTERIOR SEGMENT FINDINGS IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE.

BACKGROUND: Inflammatory bowel disease is a systemic inflammatory disease classified as Crohn disease or ulcerative colitis. It could present extra intestinal findings, such as fever, weight loss, arthralgia, mucocutaneous lesions, hepatic, renal and ophthalmological involvement. Among ophthalmological findings, posterior segment findings are present in less than 1% of patients with inflammatory bowel disease, however, these findings could bring definitive visual impairment. OBJECTIVE: Our study objective was to evaluate ocular posterior segment findings is patients with inflammatory bowel disease, through retinal mapping, color fundus retinography, optical coherence tomography (OCT) and OCT angiography, and compare our results to literature. METHODS: We evaluated eighty patients with inflammatory bowel disease through complete ophthalmological examination and posterior segment assessment. Color fundus retinography, OCT and OCT angiography was performed with Topcon Triton (Topcon ® , Tokyo, Japan). Macula and posterior pole were evaluated with binocular indirect ophthalmoscopy and fundus biomicroscopy. RESULTS: Participants mean age was 44.16 years (18.08-68.58), 28 (35%) male patients and 52 (65%) female patients. Thirty-five (44%) with diagnosis of Crohn disease, 41 (52%) patients with diagnosis of ulcerative colitis and 3 (4%) had non-conclusive Crohn disease or ulcerative colitis classification. We found abnormal exams in 21 (26.25%) patients. CONCLUSION: Our study found similar prevalence of ophthalmological posterior segment commitment compared to previous literature prevalence. The findings were predominantly unrelated to inflammatory bowel disease, rather than primarily related to it. The most prevalent, and non-previous reported, finding was increased arteriolar tortuosity, probably occurs due to systemic vascular impairment in inflammatory bowel disease.

Optical coherence tomography (OCT) angiography of central retinal artery occlusion in the patent cilioretinal artery: a case report.

Here we report the case of a 78-year-old male patient with a 2-day history of low visual acuity and fundus and who was diagnosed with central retinal artery occlusion. In addition, the patient had an allergy to fluorescein. A fundus examination of the left eye found a pink optic disc with blurred margins, diffuse pallor in the retina with arterial attenuation, and a normal band of the retinal area in the macular region. Optical coherence tomography revealed increased thickness of the inner retina. Optical coherence tomography angiography (OCT-A) revealed a decreased flow signal in the superficial layers, with reduced flow signal in the choriocapillaris. OCT-A is a valuable alternative during the follow-up period in patients with central retinal artery occlusion, particularly in those with an allergy to contrast agents. The use of this as a non-invasive examination can improve the prognosis of patients and future studies investigating the treatment of central retinal artery occlusion.

RESUMO CONTEXTO: As doenças inflamatórias intestinais são doenças inflamatórias sistêmicas que podem ser divididas em doença de Crohn ou retocolite ulcerativa. Além do quadro intestinal, elas podem apresentar sintomas extra intestinais como febre, perda de peso, artralgia, lesões mucocutâneas, acometimento hepatobiliar, acometimento renal e oftalmológico. Entre os achados oftalmológicos descritos, alterações de segmentos posterior são encontrados em menos de 1% dos pacientes com doença inflamatória intestinal, porém, tais achados podem levar à baixa acuidade visual definitiva. OBJETIVO: O objetivo do nosso trabalho foi avaliar alterações em segmento posterior através de retinografia colorida, mapeamento de retina, tomografia de coerência óptica e OCT angiography e comparar nossos resultados com o da literatura. MÉTODOS: Foram avaliados 80 pacientes com doença inflamatória intestinal. Todos os pacientes foram submetidos a exame oftalmológico completo e a avaliação do segmento posterior. Foi realizada tomografia de coerência óptica em aparelho Triton (Topcon, Tokyo, Japan), retinografia colorida e OCT angiography. Mácula e polo posterior foram avaliados através de oftalmoscopia binocular indireta e biomicroscopia de fundo. RESULTADOS: Entre os participantes, a média de idade foi de 44,16 anos (18,08-68,58), 28 (35%) participantes do sexo masculino e 52 (65%) do sexo feminino. Trinta e cinco (44%) pacientes com diagnóstico de doença de Crohn, 41 (52%) pacientes com diagnóstico de retocolite ulcerativa e 3 (4%) pacientes em que não era possível classificar como doença de Crohn ou retocolite ulcerativa. Entre as avaliações de polo posterior, foram encontrados achados em exame de 21 pacientes, o que corresponde a 26,25% dos casos. CONCLUSÃO: Nosso estudo encontrou resultados de prevalência de achados em exame de segmento posterior semelhante aos estudos prévios da literatura. Os achados foram de forma predominante não primariamente relacionados à doença inflamatória intestinal. O achado mais prevalente, e não previamente reportado, foi aumento de tortuosidade arteriolar, que provavelmente ocorre por envolvimento vascular sistêmico nas doenças inflamatórias intestinais.
