Use of Optical Coherence Tomography and Optical Coherence Tomography Angiography in the Diagnosis and Follow-Up of Endogenous Candida Endophthalmitis: A Case Report.

Background: Endogenous Candida endophthalmitis (ECE) is a rare but sight-threatening disease. Patients with ECE present with various clinical signs and symptoms, which can complicate the diagnosis. The aim of this report was to demonstrate the outcomes of treatment and to diagnose macular complications caused by intraocular inflammation. Case presentation: A 41-year-old woman with a history of acute intermittent porphyria presented with a progressive vision loss in her left eye. Left-eye OCT revealed findings consistent with a fungal etiology, which was confirmed by the culture of swabs collected from a central vein catheter. The outcomes of intravenous fluconazole treatment were not satisfactory, and the patient developed recurrent attacks of porphyria, suggesting a porphyrogenic effect of systemic antifungal therapy. Repeated intravitreal injections with amphotericin B led to a gradual regression of inflammatory lesions. However, follow-up examinations revealed active macular neovascularization (MNV) on both OCT and OCTA scans. The patient was administered intravitreal bevacizumab. At the 11th month of follow-up, OCT and OCTA scans showed significant inflammatory lesions regression with macula scarring, and no MNV activity was detected. Conclusions: This case highlights the importance of OCT and OCTA as valuable noninvasive imaging techniques for the identification of ECE, the monitoring of its clinical course, and the diagnosis of macular complications.

Abordaje interdisciplinario de endoftalmitis endógena neonatal. Reporte de caso / Interdisciplinary approach to endogenous neonatal endophthalmitis. Case report

La endoftalmitis endógena neonatal es una patología poco frecuente que puede causar daño ocular grave. Puede manifestarse en pacientes con comorbilidades, como nacimiento pretérmino, bajo peso al nacer, complicaciones posquirúrgicas perinatales o sepsis.El presente reporte de caso documenta a una paciente pretérmino que fue sometida a múltiples cirugías abdominales. Durante su internación, desarrolló sepsis, meningitis y endoftalmitis endógena neonatal. La frecuencia extremadamente baja de la endoftalmitis endógena a esta edad, la importancia de preservar la salud visual del paciente y el abordaje interdisciplinario son puntos importantes de aprendizaje en este caso.

Neonatal endogenous endophthalmitis is a rare condition that can cause serious eye injuries. It can manifest in patients with comorbidities, such as preterm birth, low birth weight, post-surgical perinatal complications, or sepsis.This case report documents a preterm patient who underwent multiple abdominal surgeries. During her hospitalization, she developed sepsis, meningitis and neonatal endogenous endophthalmitis. The extremely low frequency of endogenous endophthalmitis at this age, the importance of preserving the patient's visual health, and the interdisciplinary approach are important learning points in this case.

Foveal cone count reduction in resolved endophthalmitis: an adaptive optics scanning laser ophthalmoscopy (AO-SLO)-based prospective pilot study.

AIM: To report the foveal cone count in eyes with resolved endophthalmitis vis-à-vis normal fellow eyes using an indigenous adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS: In a prospective cross-sectional comparative pilot study, we recruited patients with resolved endophthalmitis in one eye (study eye) and a normal fellow eye (control eye). Collected data included measurement of the best-corrected visual acuity (BCVA), spectral-domain optical coherence tomography (OCT) imaging and AO-SLO imaging and cone counting at the fovea in both eyes. RESULTS: The study included 12 eyes of 6 patients. The mean age was 51.66±11.97 years (median 56 years). BCVA in all control eyes was 20/20 (logarithm of the minimum angle of resolution (LogMAR) 0), and in the study, eyes was 0.21±0.13 (median 0.19, Snellen 20/30; p=0.001; 95% CI -0.39 to -0.09). The follow-up was 18.66±12.32 (median 20 months). The cone count at the fovea in the control eye was 4356.33±1993.93 (median 4498), and in the study eye, it was 2357.16±1541.17 (median 2187.5; p=0.03; 95% CI -3556 to -1082). CONCLUSIONS: Eyes with resolved endophthalmitis with near-normal vision have reduced number of foveal cones even in absence of OCT-detected gross structural changes. TRANSLATIONAL RELEVANCE: The current work describes the application of cellular-level imaging technique called adaptive optics scanning laser ophthalmoscopy (AO-SLO) to the clinical condition of resolved endophthalmitis. The study of retinal cell biology at the cellular level is possible using the emerging technology of AO-SLO. This new investigative modality that has the potential to image the retina at the cellular level until the photoreceptors is more likely to unravel the pathophysiology of a variety of retinal diseases.

Ocular Toxocariasis: Beyond Typical Patterns through the New Imaging Technologies.

PURPOSE: To report five cases of ocular Toxocariasis (OT) in which ultrawide-field (UWF) imaging was helpful in diagnosis and assessment. OT is an underdiagnosed condition triggered by the ocular invasion of Toxocara larvae. Typical features are peripheral granuloma or endophthalmitis. METHODS: A retrospective case series of 10 outpatients were studied by complete ophthalmologic examination and complementary tests. UWF retinal imaging, fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SDOCT) were retrospectively analyzed. Five patients with suspected OT were included. RESULTS: UWF imaging and FAF was able to detect all retinal lesions in a single rapid capture. Two patients showed positive serology for Toxocara. An image suggesting the larva in the vitreous cavity was shown in one patient. Antihelmintic 15 treatment along with steroids was prescribed in two patients. CONCLUSION: UWF imaging and SDOCT provide a more efficient approach and follow-up in OT, raising final standards of care.

Endoftalmitis endógena durante el embarazo: a propósito de un caso / Endogenous endophthalmitis during pregnancy: Case report

La endoftalmitis endógena es una enfermedad que amenaza potencialmente la visión en los pacientes que la presentan. Es producida por la diseminación hematógena de microorganismos desde un foco séptico y se trata de una entidad poco frecuente que se relaciona con enfermedades debilitantes, estados de inmunosupresión y procedimientos invasivos. La endoftalmitis endógena durante el embarazo es aún más rara y se ha convertido en un desafío por la seguridad y efectos secundarios de los tratamientos locales y sistémicos que requiere para su manejo. Presentamos el caso de una mujer embarazada con antecedente de apendicitis complicada, shock séptico y trombocitopenia, con endoftalmitis endógena por Candida albicans en el postoperatorio, que requirió aplicación de antimicóticos intravítreos, sistémicos y vitrectomía, con una recuperación visual y anatómica importante, sin efectos secundarios maternos y ni fetales

Endogenous endophthalmitis is a disease that potentially threatens vision. It is produced by the haematogenous spread of microorganisms from a septic focus. It is a rare condition that is related to debilitating diseases, immunosuppression states, and invasive procedures. Endogenous endophthalmitis during pregnancy is even rarer, and has become a challenge due to the safety and side effects of the local and systemic treatments. The case is presented of a pregnant woman with a history of complicated appendicitis, septic shock, and thrombocytopenia that presented endogenous endophthalmitis due to Candida albicans in the immediate post-operative period. This required the use of intravitreal and systemic antimycotics and vitrectomy. She made a significant anatomical and functional recovery, and without any maternal or foetal side effects

Optical coherence tomography features of retinal lesions in Chinese patients with endogenous Candida endophthalmitis.

BACKGROUND: To evaluate the optical coherence tomography (OCT) features of retinal lesions in Chinese patients with endogenous Candida endophthalmitis (ECE). METHODS: We performed a retrospective review of patients diagnosed with ECE at one medical center. The medical records of the patients including predisposing risk factors, treatment and visual acuity were reviewed. And we focused on the analysis of OCT images of retinal lesions before and after treatment. RESULTS: A total of 16 Chinese patients (22 eyes) were included in this study. The most frequent predisposing risk factors were intravenous use of corticosteroids or antibiotics, lithotripsy for urinary calculi, and diabetes. After treatment, visual acuity was improved in 13 (59.1%) of the 22 eyes, and remained the same in the other 9 (40.9%) eyes. Pre-treatment OCT images obtained at presentation were available for 17 of the 22 eyes. Four types of the OCT manifestations of retinal lesions were identified: type 1 (subretinal macular lesions), type 2 (lesions are located in the inner retinal layer), type 3 (lesions involve the full-thickness retina and accompanied with macular edema), type 4 (sub-inner limiting membrane lesions). Pre-treatment OCT imaging of the 17 eyes revealed five as type 1, four as type 2, six as type 3, and two as type 4. After treatment, OCT images revealed epiretinal membrane and subretinal fibrosis as the most common post-treatment complications of ECE. Epiretinal membrane was detected in 2/4 type 2 lesions, in 4/6 type 3 lesions, and in 1/2 type 4 lesions, while subretinal fibrosis was mainly seen in type 1 lesions (4/5). Among the types, visual prognosis was best in eyes with type 2 lesions. CONCLUSIONS: In this case series, the OCT manifestations of retinal lesions in ECE could be classified into four types. The post-treatment OCT manifestations were different in four types of lesions. We preliminarily found that the OCT morphology of retinal lesions was associated with the visual prognosis of ECE.

Bilateral End-Organ Endophthalmitis in Setting of Serratia marcescens Urosepsis on 18F-FDG PET/CT.

Endogenous endophthalmitis is an uncommon infection of the internal tissues of the eye resulting from a bloodborne infection. We present the case of an 89-year-old man with Serratia marcescens urosepsis with multifocal end-organ infection on F-FDG PET/CT including aortitis, splenic abscess, septic arthritis, thoracolumbar discitis-osteomyelitis, and culture-confirmed bilateral endogenous endophthalmitis. Endophthalmitis-related intraconal ocular space uptake was clearly distinguishable from normal conal space extraocular muscle activity. Although sepsis responded to treatment, endophthalmitis led to complete vision loss. This case report presents PET/CT description of a rare and difficult-to-treat Serratia marcescens endogenous endophthalmitis, which usually has a poor visual outcome.

The incidence of endophthalmitis or macular involvement and the necessity of a routine ophthalmic examination in patients with candidemia.

BACKGROUND: The incidence of ocular candidiasis (OC) in patients with candidemia varies across different reports, and the issue of whether routine ophthalmoscopy improves outcomes has been raised. This study investigated the incidence of OC and evaluate whether the extent of OC impacts the clinical outcomes. METHODS: This retrospective study included non-neutropenic patients with candidemia who underwent treatment at one of 15 medical centers between 2010 and 2016. Chorioretinitis without other possible causes for the ocular lesions and endophthalmitis was classified as a probable OC. If signs of chorioretinitis were observed in patients with a systemic disease that causes similar ocular lesions, they were classified as a possible OC. RESULTS: In total, 781 of 1089 patients with candidemia underwent an ophthalmic examination. The prevalence of OC was 19.5%. The time from the collection of a positive blood culture to the initial ophthalmic examination was 5.0 ± 3.9 days in patients with OC. The leading isolate was Candida albicans (77.9%). Possible OC was associated with unsuccessful treatments (resolution of ocular findings) (odds ratio: 0.354, 95% confidence interval: 0.141-0.887), indicating an overdiagnosis in patients with a possible OC. If these patients were excluded, the incidence fell to 12.8%. Endophthalmitis and/or macular involvement, both of which require aggressive therapy, were detected in 43.1% of patients; a significantly higher incidence of visual symptoms was observed in these patients. CONCLUSION: Even when early routine ophthalmic examinations were performed, a high incidence of advanced ocular lesions was observed. These results suggest that routine ophthalmic examinations are still warranted in patients with candidemia.

An unexpected case of iatrogenic Escherichia coli endogenous pan-endopthalmitis after ERCP-associated biliary sepsis: A case report.

INTRODUCTION: Endogenous endopthalmitis is a diagnostically challenging ophthalmic and medical emergency. It has the ability to manifest at any age and is associated with a number of predisposing factors. The rapid progression of disease poses catastrophic risk for adverse outcomes both localised and systemic. To our knowledge, we describe the first reported iatrogenic case of endogenous Escherichia coli-induced endopthalmitis progressing to pan-endopthalmitis as a consequence of endoscopic retrograde cholangiopancreatography. DIAGNOSIS, INTERVENTIONS AND OUTCOMES: The patient presented with reduced visual acuity and painless red eye; however, apart from biochemistry results suggesting biliary sepsis, no other clinical features of acute disease were noted. Despite rigorous systemic and intravitreal treatment, the rapid progression of disease led to irreversible damage to the eye. CONCLUSION: Clinicians must maintain a very high index of suspicion when encountering patients after interventional procedures, as misdiagnosis by trained ophthalmologists for endogenous endopthalmitis remains a common occurrence. Prompt identification and diagnosis ensured our patient avoided evisceration and early ophthalmic biopsies guaranteed the correct systemic intervention was started to address the severe subsequent septicaemia.

Toxic anterior segment syndrome following phakic posterior chamber IOL: a rarity.

Implantable collamer lenses (ICL) have gained popularity for correction of myopia where kerato-refractive procedures are not indicated as in cases of high myopic refractive errors. Toxic anterior segment syndrome (TASS) is a very uncommonly reported postoperative complication following ICL implantation. A young patient developed severe corneal oedema and anterior segment inflammation on the first day after ICL implantation. Analysing retrospectively, possible idiosyncratic response to intracameral pilocarpine was considered as a cause for TASS. Prompt and intensive therapy with oral and topical potent steroids was visually rewarding. TASS, though a sterile inflammation can have catastrophic sequelae such as corneal decompensation and secondary glaucoma. Hence, timely identification and management is important.

SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY FINDINGS IN ENDOGENOUS CANDIDA ENDOPHTHALMITIS AND THEIR CLINICAL RELEVANCE.

PURPOSE: To describe vitreal, retinal, and choroidal features of eyes affected by Endogenous candida endophthalmitis (ECE) analyzed by spectral domain optical coherence tomography (SD-OCT) and to evaluate their clinical impact. METHODS: Medical records and SD-OCT images from eyes diagnosed with ECE at four retina and uveitis tertiary referral centers were retrospectively evaluated. Spectral domain optical coherence tomography images were analyzed to evaluate the structural changes occurring in the vitreous, the retina, and the choroid in areas involved by ECE. Baseline and final best-corrected visual acuity were correlated with SD-OCT findings. RESULTS: Fifteen eyes from nine patients were enrolled. Vitreous involvement (vitreous cells, posterior hyaloid thickening) was detected in 13/15 eyes. Peculiar hyper-reflective preretinal aggregates obscuring the underlying retina because of a shadowing effect ("rain-cloud" sign) were noticed in all eyes with vitreous involvement. Two patterns of retinal and choroidal findings were identified: the first (six eyes) confined within the inner retinal layers (Intraretinal Pattern), the second (nine eyes) involving both retina (full thickness) and choriocapillaris (Chorioretinal Pattern). None of the eyes showed both patterns. None of the eyes, regardless the pattern, showed choroidal thickening. Baseline best-corrected visual acuity was not associated with OCT pattern (P = 0.09). On the contrary, final best-corrected visual acuity was significantly higher in patients showing Intraretinal Pattern (∼20/25, 0.06 ± 0.08 LogMAR) than in subjects with Chorioretinal Pattern (∼20/50, 0.44 ± 0.30 LogMAR) (P = 0.01). CONCLUSION: Endogenous candida endophthalmitis showed peculiar features on SD-OCT. Two distinct patterns of chorioretinal involvement influencing the final best-corrected visual acuity were identified. Spectral domain optical coherence tomography could be useful in the diagnosis, management, and outcome prediction in ECE.
