RESUMO
Purpose: To report the application of an infrared fundus imaging and navigated laser system to photocoagulate a nematode in diffuse unilateral subacute neuroretinitis (DUSN). Observations: A 14-year-old boy with DUSN was treated with systemic albendazole and corticosteroids. Laser photocoagulation of the visible nematode was performed using a navigated laser in live infrared fundus view (Navilas 577s, OD-OS GmbH, Berlin, Germany). While the localization of the nematode was difficult in regular fundoscopy due to the light-shy helminth, it could be well localized and targeted with the infrared live video mode and navigated laser system. No inflammatory flare-up was observed after the nematode was killed. Conclusions and Importance: Laser photocoagulation and systemic antihelminthic therapy are an established treatment for DUSN. Infrared imaging and navigated laser systems seem useful in targeting and killing mobile nematodes.
RESUMO
Cat-scratch disease (CSD) is a self-limited disease caused by Bartonella henselae, a fastidious gram-negative intracellular bacillus bacterium. Neuroretinitis, a form of optic neuropathy characterised clinically by optic disc swelling and a macular star, is an uncommon manifestation of CSD occurring in approximately 1-2% of cases. We report a case of a 14-year-old female who presented to the emergency department with a chief complaint of acute painless vision loss described as a large black spot in the centre of her right eye vision 2 weeks after being scratched by cats. Fundus examination revealed Frisen grade 5 disc oedema with an atypically diffuse disc and peripapillary haemorrhages with associated subretinal fluid and a macular star in the right eye. Optical coherence tomography (OCT) of the macula and retinal nerve fibre layer showed subretinal fluid involving the fovea, a serous retinal detachment of the nasal macula, and significant optic disc oedema in the right eye. The patient was admitted and treated with doxycycline, rifampin, and prednisone taper. After completing the treatment course, the patient's vision improved, fundus examination showed significantly improved disc oedema and haemorrhages, and OCT demonstrated resolution of the subretinal fluid in the right eye.
RESUMO
Cat-scratch disease (CSD) is an infectious disease caused by Bartonella henselae, presenting with fever and lymphadenopathy following contact with felines. The ocular manifestations include neuroretinitis, characterised by optic nerve swelling and a macular star. Case Presentation: We discuss a case of neuroretinitis that presented atypically, without a macular star. There was an initial suspicion of Bartonella, but the serology was negative. Our patient was eventually empirically treated for infective neuroretinitis based on a positive contact history (recently scratched by one of his three pet cats). There was progression to a macular star upon serial dilated fundus examination, and the repeated serology one week after symptom onset showed rising titres, supporting a diagnosis of CSD. Conclusions: A judicious review of systems, repeat assays, serial dilated fundus examination, and early ophthalmic evaluation are useful in cases of suspected neuroretinitis, remaining an important differential in the evaluation of sudden-onset painless vision loss and unilateral disc swelling.
RESUMO
Introduction: Bartonella henselae, the causative agent of cat scratch disease (CSD), presents with diverse ocular manifestations, posing diagnostic challenges. This study aimed to elucidate the diagnostic complexities through a unique case. Case Presentation: A 42-year-old male presented with vision loss in the right eye, subsequent to flu-like symptoms following exposure to a stray kitten. Clinical examination revealed branch retinal artery occlusion (BRAO) in the right eye and neuroretinitis in the left, indicating concurrent ocular manifestations of CSD. Thorough investigations, including serological testing, ruled out alternative causes, highlighting the rarity of such coexisting ocular complications. Conclusions: The coexistence of BRAO and neuroretinitis in different eyes underscores the variable presentation of CSD. Recognition of infectious etiologies, particularly Bartonella, is paramount in diagnosing ocular vasculopathies. This case emphasizes the importance of considering Bartonella infection in patients with ocular vascular occlusions, especially in the context of recent cat exposure and systemic symptoms suggestive of CSD.
RESUMO
Aim: To report a case of cytomegalovirus (CMV) neuroretinitis observed in an immunocompetent patient. Materials and methods: The patient presented with a complaint of diminution of vision in both eyes (BE) and had a traumatic cataract in the right eye (RE). Fundus examination of the left eye (LE) revealed an active white, fluffy lesion with an overlying retinal hemorrhage patch with a macular star. The diagnosis of CMV neuroretinitis was established, and the patient commenced treatment with valganciclovir. Results: The patient exhibited no underlying risk factors. Subsequently, a positive response to oral valganciclovir treatment was observed. Discussion: Cytomegalovirus (CMV) neuroretinitis is typically associated with immunocompromised individuals, such as those with HIV/AIDS. The patient's presentation with a traumatic cataract in the right eye and a distinctive fundus appearance in the left eye posed a diagnostic challenge. The absence of common risk factors for CMV infection necessitated a thorough examination and consideration of rare infectious etiologies. The positive response to valganciclovir reinforces its efficacy in managing CMV-related ocular conditions. This case emphasized the necessity for ophthalmologists to maintain a high index of suspicion for CMV and other unusual pathogens when faced with neuroretinitis in patients who do not present with typical systemic immunosuppressive conditions. Early diagnosis and appropriate antiviral therapy prevent potential complications and preserve vision in such atypical presentations. Conclusion: This case underscores the importance of considering rare infectious agents in immunocompetent patients when encountering neuroretinitis, particularly in the absence of typical symptoms or signs of the disease.

Introduction: Management of patients living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (AIDS) (PLWHA) still represents a challenge for doctors in various medical fields. The presence of co-infections, with different degrees of immune system impairment, raises the need for a multi-disciplinary approach to the PLWHA. Methods: In this paper, we present three cases of PLWHA with various ophthalmological conditions, who were admitted to "Prof. Dr. Matei BalÈ" National Institute for Infectious Diseases (INBIMB). Three of them were late presenters, recently diagnosed with AIDS. All three were in immuno-virological failure. The ophthalmic conditions were either related to the HIV infection, or the result of other complications. Discussion: The diversity and complexity of ocular involvement in PLWHA were deeply linked to the patient's immunological status at the ophthalmological evaluation moment. Thus, antiretroviral therapy (ART) played an important immune status recovery role. Encountered ocular conditions vary, some being directly caused by the presence of the virus, and the others were the result of opportunistic infections (cytomegalovirus, Varicella virus) or other co-infections (Treponema pallidum). Neurological conditions disturbing the natural defense mechanism, prolonged hospital stay, and exposure to multiple antibiotic regimens are risk factors for difficult-to-treat eye infections with multidrug-resistant bacteria. Some ocular conditions can be the reason that leads to HIV infection diagnosis, while others can appear during the time, especially in patients with low ART adherence. The prognostic is conditioned by the early recognition and correct management of the disease and the immunological status recovery under ART. Conclusions: Correct and early diagnosis of HIV-related eye conditions is mandatory to establish the most appropriate medical management to obtain an increase in the quality of life of the patient.

At the end of 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China. On 11 March 2020, the World Health Organization declared COVID-19 a pandemic. This virus affects many organs, including the eye, and can manifest through various clinical manifestations. Multiple neuro-ophthalmological manifestations have been reported in association with COVID-19, including, Optic Neuritis, cranial nerve palsies, eye movement abnormalities, and visual field defects. In this article, we report a case of bilateral neuroretinitis in association with (SARS-CoV-2).
RESUMO
BACKGROUND/INTRODUCTION: Optociliary shunt vessels develop as a result of chronic retinal venous obstruction. Optic neuritis has never been reported as a causative influence. OBJECTIVE: To determine whether optic neuritis predisposes to the development of optociliary shunts in patients with multiple sclerosis. CASES: This case series follows two patients with multiple sclerosis from August 1st, 2019 to April 24th, 2024, who developed optociliary shunt vessels after attacks of optic neuritis. A 43-year-old female presented with left visual loss and bilateral superior optociliary shunt vessels. Perimetry showed bilateral peripheral visual field loss. Optical coherence tomography showed bilateral retinal thinning and ganglion cell complex loss. Optical coherence tomography angiography showed reduced capillary density bilaterally. We investigated her and eventually diagnosed her with multiple sclerosis. The second, a 49-year-old female, developed right-sided optociliary shunt vessels after an episode of neuroretinitis. Perimetry revealed bilateral central scotomata; optical coherence tomography showed disc and retinal nerve fiber layer edema, and serous retinal detachment; later, ganglion cell complex loss; and reduced capillary density on optical coherence tomography angiography. Neuroimaging revealed demyelination in both, leading to a diagnosis of multiple sclerosis, and therapy was instituted. CONCLUSIONS: We hypothesize, that demyelinating optic neuritis due to multiple sclerosis causes chronic retinal hypoperfusion, leading to subsequent optociliary shunt development in affected eyes. Our case series reveals that eyes with optic neuritis, both previous episodes and fresh cases, can contribute to sufficient retinal vein hypoperfusion to cause the development of optociliary shunts, which should be reported in the literature.
Does optic neuritis in multiple sclerosis cause optociliary shunt vessels? Our case study shows that optociliary shunt vessels have developed in eyes having previous as well as fresh optic neuritis in two multiple sclerosis patients, as demonstrated by examination and investigations. We hypothesize that multiple sclerosis causes decreased retinal perfusion predisposing to the development of optociliary shunts. This will guide neurologists and ophthalmologists in diagnosing this debilitating condition upon the visualization of optociliary shunts; heralding previous or recurrent attacks of optic neuritis. @SanaNadeemS.
RESUMO
Neuroretinitis is a potentially vision-threatening condition distinguished by swelling of the optic disc followed by the emergence of a macular star pattern. The majority of these clinical observations are typically linked to infections caused by bacteria, parasites, or viruses. We report a case of dual infections in neuroretinitis complicated with severe macular edema. A 49-year-old lady presented with sudden onset left eye blurring of vision of one-week duration. Visual acuity was 6/6 in the right eye and 6/60 in the left eye. There was a left positive relative afferent pupillary defect with impaired optic nerve functions. A fundoscopy of the left eye showed optic disc swelling with a macular star. The right optic disc was also swollen. Vasculitis changes were observed in both posterior poles. The ocular coherence tomography of the left eye revealed the existence of macular edema, subretinal fluids, and an epiretinal membrane that extended from the optic disc to the fovea. Serological examinations were positive for toxoplasma and herpes simplex virus type 1. The patient was started on oral azithromycin, oral acyclovir, and oral corticosteroids. Left macular edema persisted despite the treatment. The patient was given a trial of a single injection of intravitreal ranibizumab. A remarkable reduction of subretinal fluids was seen post-intravitreal injection and continuation of medications. Intravitreal ranibizumab has shown significant outcomes in neuroretinitis with severe macula edema.
RESUMO
We report two cases of diffuse unilateral subacute neuroretinitis (DUSN) where multimodal imaging was used to assist in locating the nematode. The first case presented with clusters of migrating choroiditis with a suspicious tiny visualized worm noted on serial fundus photography. The second case had an atypical presentation with extensive exudative retinal detachment and a suspicious coiled worm in the subretinal space noted on optical coherence tomography. Both cases received oral albendazole for six weeks while the first case received additional argon laser photocoagulation to the suspected nematode. Both cases showed resolution of the ocular inflammation upon completion of treatment with no further recurrences. DUSN should be suspected in young and healthy patients with unexplained unilateral inflammatory eye disease with severe loss of vision. This series highlights the challenges faced in identifying the nematode in cases with suspected DUSN.
RESUMO
Background: Leber's idiopathic stellate neuroretinitis (LISN) is a rare disease characterized by disk edema, peripapillary and macular hard exudates, and often, the presence of vitreous cells. To enhance clinical understanding of the disease, a retrospective analysis was conducted on a patient diagnosed with LISN at our hospital, and discussions were held regarding its diagnosis and treatment. Methods: We reviewed the medical records of a 26-year-old male patient whose main complaint was a decrease in visual acuity of both eyes for 4 days, which had worsened over the last day. After systemic examination, fundus fluorescein angiography, and indocyanine green angiography, the patient was diagnosed with LISN in both eyes. After treatment with glucocorticoids, the patient's vision showed a significant improvement. Results: Upon admission, the visual acuity of both eyes was: VOD 0.05, VOS 0.25. After 5 days of treatment, the visual acuity of both eyes was: VOD 0.25, VOS 0.4. After 1 month of follow-up, the visual acuity of both eyes was: VOD 0.4, VOS 0.6. After 5 months of follow-up, the patient's vision improved to VOD 0.6, VOS 0.8. Conclusion: The cause of LISN remains unidentified. It is essential to rule out diseases exhibiting similar clinical signs but possessing a clear etiology. The primary treatment approach involves glucocorticoid-based anti-inflammatory therapy, potentially supplemented with antibiotics, antivirals, vasodilators, and traditional Chinese medicine. This disease is usually self-limiting and generally carries a favorable prognosis.
RESUMO
Purpose: Tubulointerstitial nephritis syndrome with uveitis (TINU) is a rare, acquired syndrome characterized by interstitial nephritis with bilateral uveitis. We report a case of TINU with typical bilateral anterior uveitis complicated by an atypical, delayed-onset neuroretinitis in a 12-year old patient. Observation: A 12-year-old female with a 21-month history of TINU featuring chronic bilateral anterior uveitis presented with one week of blurred vision in her left eye. On exam she was found to have new-onset disc edema in the right eye and neuroretinitis in the left eye. After a negative infectious disease workup, the patient was treated with a course of intravenous (IV) solumedrol with prednisone taper and advancement of her systemic immunosuppression. In follow up she demonstrated resolution of her disc edema and neuroretinitis with improved visual acuity and clinical exam. Conclusion: This case stresses the importance of monitoring for additional ocular manifestations including neuroretinitis years after the onset of anterior uveitis in TINU. In comparison to the two published cases of TINU with neuroretinitis, this case shares features of uveitis progression, and thus highlights the value of further description of TINU-associated neuroretinitis.
RESUMO
BACKGROUND: Cat-scratch disease (CSD) is caused by Bartonella henselae infection. In atypical cases of CSD, pathogen determination is challenging. We report a case of Bartonella neuroretinitis with neither a clear history of scratches nor typical general symptoms. The diagnosis was made using metagenomic next-generation sequencing (mNGS), a high-throughput sequencing technology. CASE PRESENTATION: A female patient presented to the ophthalmologist with complaint of blurred vision in her right eye. Although with history of raising a cat, she reported no clear history of scratches or typical general symptoms, except a fever of unknown origin which resolved spontaneously. The best corrected visual acuity (BCVA) of the right eye was count fingers. Fundus examination showed optic disc oedema, macular exudates and inferior exudative retinal detachment. Laboratory examination results showed increased value of serum C-reactive protein and erythrocyte sedimentation rate. Ocular involvement of toxoplasmosis, syphilis and tuberculosis were excluded. To identify the possible causative pathogen of the disease, mNGS of aqueous humour sample was performed and 521 reads of B. henselae were identified. Serological test results further showed a positive immunoglobulin G (IgG) titre of 1:64. Taking the contact history, clinical manifestations, mNGS and serological results into consideration, the diagnosis of Bartonella neuroretinitis (ocular CSD) was made. After appropriate treatment, the BCVA of the right eye improved to 20/25 in the last follow-up. Fundus examination showed a normal optic disc and macula, and the exudates had reduced. CONCLUSION: mNGS, a fast and unbiased method, can be used to detect B. henselae (if present) in intraocular fluid samples.; however, the results should be interpreted together with the clinical symptoms and other auxiliary test results.

PURPOSE: To describe an unusual case of Whipple's disease (WD) complicated by uveitis, and subsequent paradoxical worsening after effective antibiotic treatment targeting Tropheryma whipplei (TW). METHODS: Case report. RESULTS: A 53-year-old male presented with bilateral knee arthritis, weight loss, chronic low-grade fever, and cognitive disorders. He was under treatment with tumor necrosis factor α inhibitors (TNFi) for seronegative spondyloarthritis. Given this unusual clinical presentation, further investigations were performed and revealed blood, saliva, stool, synovial fluid and cerebrospinal fluid positivity for TW, confirming the diagnosis of systemic WD. Ophthalmologic examination revealed bilateral posterior uveitis and an aqueous humor sample confirmed the presence of intraocular TW. TNFi were stopped, and the patient was subsequently treated with adequate antibiotics (ceftriaxone, followed by doxycycline and hydroxychloroquine), and subconjunctival corticosteroid injections. After a transient improvement of the ocular symptoms, he presented a recurrence of posterior segment inflammation, leading to repeated PCR testing for TW which were negative. Therefore, paradoxical worsening of the inflammation in the context of immune recovery uveitis (IRU) was thought to be the culprit. The patient was treated with systemic corticosteroid therapy, allowing for rapid improvement of the ocular findings. CONCLUSIONS: This case underlines the possibility of IRU complicating WD. Ophthalmologists, rheumatologists, and internists should be aware of this rare complication, particularly in the context of previous immunosuppressive therapy.
RESUMO
BACKGROUND: To present the clinical characteristics of neuroretinitis in Korea. METHODS: Twelve patients with neuroretinitis between January 2009 and September 2020 were retrospectively reviewed. Neuroretinitis was diagnosed based on fundus findings, optical coherence tomography, and fluorescein angiography. The serological findings of each patient were reviewed. RESULTS: Fifteen eyes of 12 patients (9 male and 3 female), with a mean age of 46.0 ± 10.7 years were included. Of the nine patients who underwent serological testing for Toxocara antibodies, six (66.6%) were positive. One patient had high titers of Toxoplasma immunoglobulins M and G. One patient diagnosed with dengue fever was suspected to have neuroretinitis in both eyes. There were no related abnormalities in the serological findings in four patients (33.3%) out of 12 patients. There were no suspected cases of cat-scratch disease. The six patients who were positive for Toxocara antibodies were older (mean age: 54.5 ± 9.1 years) than the others (mean age: 37.5 ± 4.4 years, p = 0.004). The four patients without any abnormal serological findings were relatively younger (mean age: 35.7 ± 3.0 years) than the other 8 patients (mean age: 51.1 ± 10.1 years, p = 0.008). CONCLUSIONS: Two-thirds of neuroretinitis patients were seropositive for Toxocara in the current cohort from Koreans. Causative factors in cases of neuroretinitis may vary according to age and region.

Ocular tuberculosis (TB) may present with various clinical manifestations and may involve any part of the eye. In 80% of cases, pulmonary involvement is not found. Here, we are presenting three cases of presumptive ocular TB with three rare manifestations. The first case is of bilateral retinal detachment involving one eye after another, the second case is of tubercular phlyctenular keratoconjunctivitis with keratolysis, and the third case is of bilateral neuroretinitis with extensive cerebral involvement. Despite the availability of various tests, clinical findings, tuberculin skin test, chest X-ray, and computed tomography of the chest is still the primary basis of diagnosis of ocular TB in the tubercular endemic area, even in rare cases.
RESUMO
BACKGROUND: Neuroretinitis is classically defined as a clinical triad of unilateral, painless vision loss, accompanied by optic disc edema and characteristic macular star formation. The causes of neuroretinitis can be categorized as infectious, non-infectious, and idiopathic, therefore differential diagnosis and careful evaluation are required, owing to the various etiologies and masqueraders. CASE PRESENTATION: A 54-year-old woman presented to the clinic with blurred vision in both eyes. A complete ophthalmic examination revealed optic disc edema with blurred margins and macular exudates, intraretinal edema in the temporal peripapillary area, and subretinal fluid with neurosensory retinal detachment in the macular area. Systemic laboratory investigations showed no signs of infection or inflammation. However, bone marrow suppression was suspected based on the results of the complete blood count test, and the patient was diagnosed with multiple myeloma. CONCLUSION: Although neuroretinitis is rarely accompanied by hematological malignancy, it is important to be mindful of the latter because ophthalmic manifestations are a common feature of hematological malignancies and lesions occur in nearly every ocular structure.

In this case report, a patient with neuroretinitis from a Bartonella henselae infection is described, and insights into methods to distinguish this type of case from more common etiologies of optic nerve edema are presented. A 21-year-old female with a history of right monocular vision loss due to amblyopia presented to the emergency department (ED) with occipital headache, fever, dizziness, nasal congestion, and painless blurry vision in the left eye for one day. A lumbar puncture found a slightly high opening pressure but no evidence of meningitis. The patient was diagnosed with a viral illness and discharged with outpatient follow-up. The patient, however, had persistent central vision loss and recurring headaches and returned to the ED. Subsequent ultrasound of the patient's optic nerve revealed significant optic nerve swelling. A new working diagnosis of idiopathic intracranial hypertension was made, and the patient was started on oral acetazolamide. On the next day, she was seen by ophthalmology, and recent scratches from her cat were noted on her arm. She tested positive for B. henselae and was started on doxycycline and rifampin. Nearly two weeks after the initial presentation, a macular star pattern, indicative of neuroretinitis, was noted on the fundoscopic exam. The patient had recovered her vision by three months later. In ED cases with unilateral vision loss, early use of point-of-care ultrasound and infection with B. henselae should always be considered. Early serology testing may be warranted to allow for earlier treatment since classic signs of neuroretinitis may not be apparent at the onset.
RESUMO
Objectives: To present the clinical and demographic characteristics, imaging findings, diagnosis and treatment approach in cases of cat scratch disease (CSD) with ocular involvement. Materials and Methods: The records of 19 patients followed-up and treated between 2010 and 2020, including detailed ophthalmological examinations, imaging findings, and treatment approach, were evaluated retrospectively. Results: Twenty-three eyes of 19 patients, 7 female (37%) and 12 male (63%), were included in the study. The mean age was 34.1±13.3 (range: 11-56) years, and the mean follow-up duration was 12.6±18.0 (range: 1-81) months. Unilateral involvement was observed in 15 cases (79%). Cat contact was reported in 14 cases (74%). In 6 cases (32%), flu-like symptoms were present before the ocular complaints. The mean visual acuity (VA) at presentation was 0.42±0.36 (range: 0.001-1.0). Anterior uveitis was observed in 3 eyes (13%). Posterior segment findings included neuroretinitis in 14 (61%), superficial retinal infiltrate(s) in 8 (35%), papillitis in 3 (13%), branch retinal artery occlusion in 2 (8%), and cilioretinal artery occlusion in 1 (4%) of the eyes. All cases were positive for Bartonella henselae immunglobulin (Ig)M and/or IgG. Systemic antibiotic therapy was administered to all patients. Intravenous pulse or oral corticosteroids were given, especially in cases with optic disc involvement. The mean final VA was 0.80±0.25 (range: 0.01-1.0). Conclusion: CSD may present with different ocular involvement patterns. Apart from the classical neuroretinitis and macular star appearance, patients may present with isolated optic disc edema, branch retinal artery occlusion, and retinal infiltrations. In such patients, cat contact history and Bartonella serology should be evaluated to differentiate CSD.
