Introduction: Cat scratch disease is a pleiomorphic condition, sometimes with isolated ophthalmic involvement. We report the clinical observations of seven cases with ophthalmologic manifestations of cat scratch disease., Observations: There were seven patients, with a median age of 52 years, of whom five were women and three had unilateral involvement. Six exhibited Leber's stellate neuroretinitis, an incomplete syndrome in two cases, and one associated with chorioretinal foci. One patient had isolated retinal infiltrates. The diagnosis of cat scratch disease was confirmed by Bartonella henselae serology, positive in all cases. All patients received treatment with doxycycline. Ocular complications (with optic atrophy and macular retinal pigment epithelial changes) were noted in five cases., Discussion: Ocular bartonellosis is an atypical clinical form. It requires a directed ancillary work-up with serology or PCR, which has the peculiarity of being highly specific if not very sensitive. Treatment is above all preventive. Antibiotics may be initiated., Conclusion: Cat scratch disease must be excluded in the work-up of posterior uveitis., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

To report the first case of choroidal neovascularisation (CNV) that appeared during the primary Bartonella henselae infection in an 8-year-old girl. An 8-year-old girl was referred to our clinic complaining of a central scotoma in the right eye. Fundus examination revealed a bilateral disc oedema and in the right eye neuroretinitis with macular star and CNV, which was confirmed by fluorescein angiography. The optical coherence tomography revealed the presence of macular serous retinal detachment. Laboratory analysis showed rising IgM and IgG titres for B. henselae. Cat-scratch disease was diagnosed, and an 8-week treatment with azithromycin was initiated. In addition, an intravitreal injection of ranibizumab was performed in the right eye to treat the CNV. A month later, we decided to administer a systemic antibiotic again for an additional 5 months, due to the persistence of papillitis. Cat-scratch disease should be considered among the different causes of inflammatory CNV secondary to infectious uveitis. Our case was the first described in the literature in which a CNV appeared during the primary infection and not as a later complication. The combination of systemic antibiotic treatment with intravitreal anti-VEGF therapy was a successful choice because it allowed us to obtain the complete resolution of neuroretinitis, associated with the scarring of the choroidal neovascular membrane, with a final visual acuity of 20/20 in both eyes.

Optic neuropathy due to cat scratch disease (CSD) is a rare occurrence associated with macular star formation and is characterised by sudden mostly unilateral painless loss of vision. The aetiological agent in CSD is Bartonella henselae. Ocular complications present in up to 10% of patients and include neuroretinitis, conjunctivitis or uveitis. Ocular bartonelosis is usually self-limited. A case of a man patient with neuroretinitis caused by B. henselae is reported., (2015 BMJ Publishing Group Ltd.)

This case report describes Bartonella henselae neuroretinitis in a 26-year-old woman who presented to the emergency department with unilateral central scotoma and no prodromal symptoms, a unique presentation of this disease. B henselae, a gram-negative bacteria, is the cause of cat scratch disease. Cat scratch disease (CSD) is a self-limiting illness, which typically presents with regional lymphadenopathy, fever, and small skin lesions in associationwith a cat scratch or bite. The mostcommon ocular manifestations of cat scratch disease are Parinaud oculoglandular syndrome and neuroretinitis. All prior reported cases of CSD neuroretinitis presented with prodromal symptoms, not vision loss alone.

The case of a 36 year-old male with neuroretinitis caused by Bartonella henselae is reported, whose periodic follow-up was done through optical coherence tomography (OCT). The onset of this disease was characterized by unilateral low visual acuity (VA), painless, of sudden onset, in the right eye (RE), associated to l febrile symptom. The funduscopic examination showed edema in the posterior pole which extended from the optical disc to the macular region in the RE. The OCT confirmed macular and optical disc thickening, as well as the presence of subretinal macular fluid. Systemic studies were normal except for a blood count due to the presence of leukocytosis and positive for Bartonella henselae. The follow up with CT Scan helped to evaluate the decrease in macular edema, with the subsequent improvement of visual acuity and absence of related complications. This report describes the utility of the follow up with OCT in a patient with neuroretinitis caused by Bartonella henselae.

Cat scratch neuroretinitis (CSN) is a clinical diagnosis supported by serological testing. We present 2 cases of CSN in which initial acute titers were negative or equivocal for Bartonella henselae while convalescent titers were shown to be positive. We report these cases to emphasize that a single acute negative titer is insufficient to exclude the diagnosis of CSN and that convalescent titers should be obtained in patients for whom there is a high clinical suspicion of the disease.

We report a case of cat-scratch disease with unusual posterior segment manifestations. A 12-year-old healthy male presented with three weeks history of decreased visual acuity in the right eye. A significant history of cat exposure and elevated Bartonella titers were present. A large white-gray vascularized mass extending off the optic disk, an early stellate maculopathy, a plaque of choroiditis, an inferior serous retinal detachment involving the macula were present in the right eye. Sector papillitis and a focal area of chorioretinitis along the superotemporal arcade with associated retinal artery to vein anastomosis were present in the left eye. Bilateral optic nerve head involvement including peripapillary angiomatosis, retinal-retinal anastomosis and plaque choroiditis as ocular complications of cat-scratch disease have not been previously described to our knowledge and make this case noteworthy.

Purpose: Bartonella henselae, the cause of cat-scratch disease in humans, may lead to characteristic vision-threatening ocular findings, which importantly indicate diagnosis., Methods: This is an observational case report of a 6-year-old boy who presented with bilateral stellate maculopathy and lymphadenopathy., Results: After serologic verification of B. henselae infection, systemic azithromycin therapy initiated the full recovery of visual acuity and bilateral complete resolution of stellate exudates during the following months., Conclusion: Stellate maculopathy should always include the differential diagnosis of B. henselae infection. In this rare case of bilateral stellate maculopathy, we observed full recovery of function following systemic macrolide therapy.

Objective: To describe the clinical manifestations and to identify risk factors associated with visual outcome in a large cohort of patients with cat scratch optic neuropathy (CSON)., Design: Multicenter, retrospective chart review., Participants: Fifty-three patients (62 eyes) with serologically positive CSON from 5 academic neuro-ophthalmology services evaluated over an 11-year period., Methods: Institutional review board/ethics committee approval was obtained. Data from medical record charts were collected to detail the clinical manifestations and to analyze visual outcome metrics. Generalized estimating equations and logistic regression analysis were used in the statistical analysis. Six patients (9 eyes) were excluded from visual outcome statistical analysis because of a lack of follow-up., Main Outcome Measures: Demographic information, symptoms at presentation, clinical characteristics, length of follow-up, treatment used, and visual acuity (at presentation and final follow-up)., Results: Mean patient age was 27.8 years (range, 8-65 years). Mean follow-up time was 170.8 days (range, 1-1482 days). Simultaneous bilateral involvement occurred in 9 (17%) of 53 patients. Visual acuity on presentation ranged from 20/20 to counting fingers (mean, 20/160). Sixty-eight percent of eyes retained a visual acuity of 20/40 or better at final follow-up (defined as favorable visual outcome). Sixty-seven percent of patients endorsed a history of cat or kitten scratch. Neuroretinitis (macular star) developed in 28 eyes (45%). Only 5 patients had significant visual complications (branch retinal artery occlusion, macular hole, and corneal decompensation). Neither patient age nor any other factor except good initial visual acuity and absence of systemic symptoms was associated with a favorable visual outcome. There was no association between visual acuity at final follow-up and systemic antibiotic or steroid use., Conclusions: Patients with CSON have a good overall visual prognosis. Good visual acuity at presentation was associated with a favorable visual outcome. The absence of a macular star does not exclude the possibility of CSON., Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article., (Copyright © 2012 American Academy of Ophthalmology.

We report a case of cat-scratch disease neuroretinitis. A 26-year-old man was referred for severe right visual loss. Posterior segment examination showed a papilledema with macular edema. Bartonella henselae immunoglobulin G testing was positive. Four weeks of antibiotic therapy combining oral ciprofloxacin and doxycycline led to progressive resolution of the neuroretinitis and improvement in visual acuity. This report reminds that B. henselae infection can be the cause of neuroretinitis. Its prognosis can be improved by early treatment., (Copyright © 2010 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.)

Optic neuropathy due to cat scratch disease is a relatively infrequent occurrence associated with macular star formation and is characterized by sudden painless loss of vision mostly unilateral. Bartonella henselae is well recognized as the etiologic agent in cat scratch disease. Ocular complications of the disease occur in up to 10% of patients and include neuroretinitis. Ocular bartonelosis is usually self-limited with complete or near-complete recovery of vision in otherwise healthy patients. A case of a boy with neuroretinitis caused by B. henselae is reported.

Cat scratch disease is the main clinical presentation of Bartonella henselae infection. However, ocular manifestations of bartonellosis occur in about 5 to 10% of the patients, mainly presenting as neuroretinitis, choroiditis or oculoglandular syndrome of Parinaud. We describe two patients with documented B. henselae infection and typical ocular compromise. Both patients were treated and had a favorable visual outcome.

To describe the intra-ocular manifestations of cat-scratch disease (CSD) found at two uveitis reference centers in Brazil. Retrospective case series study. Review of clinical records of patients diagnosed with CSD in the Uveitis Department of São Geraldo Hospital and the Ophthalmology Department of the Instituto de Pesquisa Clínica Evandro Chagas-FIOCRUZ, from 2001 to 2008. In the 8-year period, 24 patients with the diagnosis of CSD were identified. Twelve patients were male and 12 female. The mean age was 27.04 years (range 7-56). Sixteen patients (66.6%) presented with a history of a cat scratch and all patients reported cat exposure. Visual acuity ranged from counting fingers to 1.0 in the affected eye. Thirteen patients presented with bilateral disease. Sixteen (66.6%) patients complained of systemic symptoms, including fever, lymphadenopathy, liver and spleen enlargement and rash. All patients presented with serum antibodies (IgG) to Bartonella henselae. Thirty-seven eyes were affected. The most common findings were small areas of retinal infiltrates which occurred in 11 eyes (29.7%) and angiomatous lesions which occurred in nine eyes (24.3%). Neuroretinitis occurred in only six eyes (16.2%). The most common findings of CSD in our study were retinal infiltrates and angiomatous lesions. CSD patients may present with significant visual loss. Patients may benefit from systemic treatment with antibiotics.

Bartonella henselae is the causative agent of cat scratch disease, a human infection usually characterized by persistent regional lymphadenopathy. It is transmitted to humans by cat scratches or bites. Cats are the major reservoir for this bacterium thus B. henselae has a worldwide distribution. The bacterial pathogenicity may bay emphasized by the immune status of the infected host. Angiomatosis or hepatic peliosis are the most frequent clinical manifestations in immunocompromised patients. B. henselae is also responsible for endocarditis in patients with valvular diseases, and may induce various clinical presentations such as: bacteriemia, retinitis, musculoskeletal disorders, hepatic or splenic diseases, encephalitis, or myocarditis. Several diagnostic tools are available; they may be combined and adapted to every clinical setting. B. henselae is a fastidious bacterium; its diagnosis is mainly made by PCR and blood tests. No treatment is required for the benign form of cat scratch disease. For more severe clinical presentations, the treatment must be adapted to every clinical presentation.

A 15-year-old girl being treated with imatinib for chronic myelogenous leukemia (CML) presented with acute vision loss in her right eye accompanied by swelling of the right side of her neck. On examination, she was found to have disk and macular edema of the right eye. Fine-needle aspiration and excisional biopsies of an enlarged submandibular lymph node were negative for malignancy. Although initial serologies were equivocal for Bartonella henselae, repeat serologies performed 1 week later upon the appearance of a macular star were positive. This is the first reported case of B. henselae in a patient with CML.

Cat-scratch disease is a clinical syndrome that usually presents as a self-limiting illness featuring regional lymphadenopathy, fever, and small skin lesions in association with a cat scratch or bite. It is caused by the Gram-negative bacillus Bartonella henselae, which commonly affects children and young adults. Ocular bartonellosis is the most common atypical manifestation of cat-scratch disease. It can present with a wide spectrum of ocular diseases including neuroretinitis, Parinaud's oculoglandular syndrome, and other forms of intra-ocular inflammation. This case report describes cat-scratch disease neuroretinitis in a 10-year-old girl who presented with typical signs, including optic disc swelling and a macular star, preceded by pyrexia of unknown origin and cervical lymphadenopathy.

Purpose: Bartonella henselae is the causal agent of cat scratch disease and one variation in its presentation is Leber neuroretinitis. The unilateral presence of exudation as a macular star and papilledema represent its most common presentation., Methods: Observational case report. A 7-year-old girl presented a sudden decrease of visual acuity and bilateral macular exudation (macular star) as well as choroiditis., Results: A complete recovery of visual acuity was seen after a 6-week follow-up. Erythromycin plus deflazacort treatment was given., Conclusions: The present case represents an unusual variety of cat scratch disease. This represents a challenge in the differential diagnosis of diseases such as Lyme disease and tuberculosis among others.

About 80% of cat-scratch disease (CSD) infections occur in children, and CSD neuroretinitis (optic neuropathy with retinal exudates in a "macular star" pattern) mostly occurs in children and young adults. A recent study suggested that CSD optic neuropathy has specific features on MR imaging. However, MR imaging findings in CSD neuroretinitis are not well described in the pediatric literature. We present a patient with CSD neuroretinitis in whom these specific MR imaging features preceded the macular star, a funduscopic finding strongly suggestive of neuroretinitis. This case demonstrates how knowledge of these features is important in the appropriate diagnostic work-up of optic neuropathy. MR imaging also incidentally revealed neuritis of another cranial nerve in the auditory canal-a rare manifestation of CSD.

We report a case of cat-scratch disease neuroretinitis for which systemic and ocular investigations proved the responsibility of Bartonella henselae. An 11-year-old boy was referred to the hospital in November 2002 for severe visual loss in the left eye over the preceding 2 weeks. At the same time, he also developed a flu-like illness. The best corrected acuity in the left eye was counting fingers at 30 cm. Posterior segment examination on the left eye showed an optic disk edema with papillary and peripapillary hemorrhages and serous retinal detachment, mild vitreous inflammation, and two little perivascular white spots. The medical history was unremarkable except for a cat scratch on his left forearm 2 months before. Four weeks of antibiotic therapy including oral rifampin and doxycycline was used. Bartonella henselae immunoglobulin M were first detected with Bartonella henselae immunoglobulin G testing negative at this time. A 3-week serum showed immunoglobulin M seroreversion, while Bartonella henselae immunoglobulin G appeared. Other causes of optic disk edema with macular star were excluded by biological data. Bartonella antibodies to both Bartonella henselae and Bartonella clarridgeiae were detected in the cat. Ophthalmic follow-up showed progressive resorption of the neuroretinitis and the visual acuity increased to 5/10. The significance of this case report lies in the reminder that this pathology can be the cause of neuroretinitis; the prognosis can be improved by earlier treatment.

Purpose: To report a case of Bartonella henselae infection., Design: Observational case report., Methods: Review of the clinical, laboratory, photographic, and angiographic records of a patient with cat scratch disease associated with central retinal artery and vein occlusion, neovascular glaucoma, and severe vision loss., Results: A 21-year-old man had no light perception in the left eye secondary to concurrent central retinal artery and vein occlusion believed to have resulted from infection with Bartonella henselae. Forty days later, he developed neovascular glaucoma in the left eye., Conclusion: Ocular complications associated with Bartonella henselae infection may include central retinal artery and vein occlusion, neovascular glaucoma, and severe vision loss.

Purpose: To clarify the prevalence and clinical profile of neuroretinitis associated with cat-scratch disease (CSD) in Japan., Methods: Japanese patients were searched using a computer web site, Japana Centra Revuo Medicina. Location of patients, medical history, systemic and intraocular findings, treatments and visual outcome were examined., Results: We reviewed 15 eyes of 14 patients, including our own case. Incidences of the disease were more common in summer than in winter and presented in the warmer parts of Japan. All patients had been previously healthy and had been exposed to cats or flea bites. Of the 14 patients, 13 (93%) had febrile illness and seven of these (54%) had lymphadenopathy. Uveitis and macular stars were observed in 11 of 15 eyes (73%). Most patients were treated with antibiotics and systemic steroids and visual prognoses were good., Conclusions: The clinical features of CSD-associated neuroretinitis in Japan are similar to those in other countries. Its distribution may correlate with the prevalence of Bartonella henselae-seropositive cats in Japan.

Background: Cat scratch disease neuroretinitis is caused by infection by Bartonella henselae. To demonstrate B. henselae infection, serologic examination is commonly used, but sometimes serologic examination is not adequate for correct diagnosis. Here we present a case of cat scratch disease neuroretinitis confirmed by polymerase chain reaction in addition to serologic examination., Case: A 55-year-old woman, presenting with headache and high fever, had noticed visual disturbance. The best-corrected visual acuity in her right eye was 0.01. Meningitis, optic neuritis and retinitis were observed and she was treated with oral prednisolone. After repeated questioning, the patient remembered being scratched by a cat. Systemic examination focusing on B. henselae infection was conducted and B. henselae-specific immunoglobulin (Ig) G, but not IgM, was detected in both serum and cerebrospinal fluid. To confirm B. henselae infection, polymerase chain reaction (PCR) analysis using cerebrospinal fluid was performed and the presence of B. henselae-specific DNA was demonstrated. From these results, we diagnosed cat scratch disease neuroretinitis and treated the patient with minocycline hydrochloride together with prednisolone. Following this treatment regimen, the patient's condition improved, and the best-corrected visual acuity in her right eye increased to 0.6 five months after the onset., Conclusion: The PCR technique is useful to correctly diagnose cat scratch disease neuroretinitis, if patients exhibit marginal data on B. henselae-specific antibody titer.

Purpose/methods: To report the clinical case of a 34-year-old male with atypical ophthalmic manifestations of cat-scratch disease (ocular bartonellosis), including an extensive retinal phlebitis, as well as the evolution of the clinical picture with treatment., Results/conclusions: The clinical diagnosis of ocular bartonellosis was serologically confirmed. Oral treatment with ciprofloxacine healed the phlebitis and the neuroretinitis, with a residual optic disk pallor. This case exemplifies the diversitiy of ocular manifestations of this disease. The authors recommend considering this condition in the differential diagnosis of posterior uveitis in young patients.

Purpose: To assess the value of polymerase chain reaction in the diagnosis of cat-scratch disease neuroretinitis without conclusive serology., Methods: Interventional case report. A 13-year-old girl developed a right neuroretinitis 2 months after a cat scratch. Despite the lack of accompanying features, an infection by Bartonella henselae was suspected and a systemic check-up was performed., Results: Serologic results excluded other proposed origins but were insufficient in making the diagnosis because of low B. henselae specific IgG level in serum. A polymerase chain reaction analysis for B. henselae DNA in a small axillary lymphadenopathy aspirate enabled us to achieve a definitive diagnosis of cat-scratch disease., Conclusion: Polymerase chain reaction is a valuable method of diagnosing cat-scratch disease when serology is considered negative or borderline.

Case Report: We present a 35 year-old man, suffering from HIV infection with a left neuroretinitis and bilateral multifocal inner retinitis. A systematic approach supported the presumed diagnosis of cat-scratch disease. The patient was treated with oral azytromicine following a full-clinical recovery., Discussion: We discuss the differential diagnosis of this clinical entity, treatment and clinical evolution.

Background: Cat-scratch disease is a subacute regional lymphadenitis, usually preceded by a history of a cat scratch or exposure to kittens. The disease is caused by Bartonella henselae, and possibly Bartonella quintana, pleomorphic gram-negative rods formerly known as Rochalimaea henselae and Rochalimaea quintana. Ocular involvement is rare and typically manifests as either Parinaud's oculoglandular syndrome or neuroretinitis. Patients with neuroretinitis resulting from cat-scratch disease may be asymptomatic or experience mild-to-severe vision loss. The clinical features, angiographic appearance, differential diagnosis, and management of cat-scratch neuroretinitis are discussed., Case Report: A 30-year-old white woman reported to the eye clinic with painless, decreased vision in the right eye. A diagnosis of cat scratch neuroretinitis was made on the basis of the history of cat scratch, clinical appearance, and angiographic findings. Treatment with oral ciprofloxacin restored vision to normal in 4 weeks., Conclusion: Painless vision loss associated with optic nerve swelling and macular star exudate should alert suspicion of systemic disease. Additional findings--including positive history of a cat scratch, lymphadenopathy, and flu-like symptoms--may indicate Bartonella henselae or Bartonella quintana infection. While treatment remains controversial, appropriate serology testing may aid in the diagnosis and management of the underlying infection.

Background: Bartonella henselae has been identified as the causative agent of the neuroretinitis associated with cat scratch disease (CSD). Immunofluorescent antibody tests with good sensitivity and specificity are available to aid in diagnosis. Despite diagnostic advances, optimal management remains controversial. We present a case of documented B. henselae macular neuroretinitis managed without antibiotics and discuss antibiotic use in this condition., Methods: We examined a young woman with macular neuroretinitis and established a diagnosis of CSD. Management consisted of a review of the literature, followed by educating her about the condition and close observation. We documented the course of her disease., Results: We diagnosed neuroretinitis associated with B. henselae infection based on immunofluorescent antibody titres and clinical presentation. Our patient's neuroretinitis resolved promptly without antibiotic therapy., Conclusions: Macular neuroretinitis in CSD can be satisfactorily diagnosed with the use of fluorescent antibodies in the appropriate clinical setting. Optimal treatment for the disease has not been established and observation combined with patient education remains an appropriate option. The self-limited nature of the disease implies that treatment studies not using controls must be interpreted with great caution. Adverse drug reactions and other iatrogenic complications can be reduced by limiting antibiotic use in settings where a meaningful treatment benefit has not been established.

Background: The spectrum of diseases caused by Bartonella henselae continues to expand and ocular involvement during this infection is being diagnosed with increasing frequency., Methods: The clinical features and visual prognosis for 13 patients with intraocular inflammatory disease and laboratory evidence of bartonellosis were investigated. There were nine patients with neuroretinitis and four with panuveitis with positive antibody titres against B henselae determined by an enzyme immunoassay (IgG exceeding 1:900 and/or IgM exceeding 1:250)., Results: Positive IgG levels were found for eight patients and positive IgM levels for five. Despite animal exposure of 10 patients, only two (IgG positive) cases had systemic symptoms consistent with the diagnosis of cat scratch disease. Pathological fluorescein leakage of the optic disc was observed in all affected eyes. At 6 months' follow up, 3/18 (17%) affected eyes had a visual acuity of less than 20/100, owing to optic disc atrophy and cystoid macular oedema. 12 patients (17 eyes) were treated with antibiotics; visual acuity improved two or more Snellen lines for 9/17 (53%) eyes., Conclusions: The possibility of B henselae infection should be considered in patients with neuroretinitis and panuveitis (especially in cases with associated optic nerve involvement) even in the absence of systemic symptoms typical for cat scratch disease.

Purpose: To report atypical clinical features of Bartonella henselae neuroretinitis treated with combination antibiotics., Method: Case report., Results: A 20-year-old man with a positive B. henselae titer developed a unilateral neuroretinitis, a large peripapillary angiomatous lesion, branch artery occlusion with ischemic maculopathy, and vision loss that failed to improve with clindamycin. Treatment with doxycycline and rifampin led to rapid clinical improvement. The severe vision loss in this case is atypical., Conclusions: Ocular findings associated with B. henselae infection may include retinal angiomatous lesion and branch retinal artery occlusion. Doxycycline and rifampin were successful in treating the infection.
