The Prevalence and Characteristics of Inflammatory Bowel Disease-related Ocular Involvement in Children.

BACKGROUND: Ocular manifestations (OMs) in patients with inflammatory bowel disease (IBD) are uncommon, particularly in children. We aimed to explore the prevalence and characteristics of IBD-associated OM in a large cohort study. METHODS: A cross-sectional study was performed using the Maccabi Healthcare Services (MHS) database. The eligible population included all patients diagnosed with IBD as children (<18 years) between January 2005 and July 2023. RESULTS: Out of 2567 children with IBD (males 55%, Crohn's disease 64%), 78 (3%) were diagnosed with OM at any time during the disease course. In 54 patients (69%), the ocular disease occurred after IBD diagnosis with a median time of 2.6 (0.47-7) years between the 2 events, whereas in 24 patients (31%), ocular involvement preceded IBD diagnosis with a median time of 2.1 (0.6-5.7) years. The presence of ocular involvement was associated with increased usage of systemic corticosteroids (P < .001) and biologic agents (P = .04). There were 55 patients with ocular involvement during childhood who were ever diagnosed with IBD. In this population, ocular involvement was also associated with increased usage of systemic corticosteroids (P < .001). The prevalence of OM among patients with IBD did not change significantly over time (P = .75), with a prevalence of 2.3% at the end of the study period. CONCLUSIONS: The prevalence of ocular involvement in children with IBD is rare and steady; it is also associated with a greater usage of systemic corticosteroids and biologic agents, potentially representing a more severe disease course.

The prevalence of ocular manifestations in children with inflammatory bowel diseases is 2.3%, steady over the years. Ocular manifestations were associated with systemic steroids and biologic agents treatment, potentially representing severe inflammatory bowel disease.

ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR TREATMENT IN DIABETIC MACULAR EDEMA: RESULTS FROM A LARGE SINGLE-CENTER COHORT WITH BEVACIZUMAB AS FIRST-LINE THERAPY.

PURPOSE: To explore visual acuity (VA) outcomes of anti-vascular endothelial growth factor (VEGF) intravitreal injections in treatment-naive eyes with diabetic macular edema (DME), with bevacizumab as first-line treatment. METHODS: Retrospective single-center cohort study over a three-year follow-up. Overall, 1765 eyes from 1179 patients treated with intravitreal injections were evaluated. The cohort was divided according to the treatment given: (1) bevacizumab monotherapy, (2) eyes switched to a second-line agent, and (3) eyes switched to a third-line agent. RESULTS: In total, 644 eyes of 444 patients met inclusion criteria. The mean age at presentation was 64.0 ± 11.1 years. The mean follow-up period was 24.6 ± 12.4 months. Furthermore, 67.1% of eyes were treated with bevacizumab monotherapy, 25.45% switched to a second-line agent, and 7.45% were switched to a third-line agent. The mean number of injections decreased significantly during each treatment year in the total cohort and within each treatment group ( P < 0.001). Mean VA for the total cohort and within each treatment group improved significantly throughout follow-up ( P < 0.001). No significant difference in VA was found between the groups ( P = 0.373). CONCLUSION: This real-world study demonstrates robust and consistent VA gains over long-term follow-up in eyes with DME treated with either bevacizumab monotherapy or switching to alternative anti-VEGF agents in cases of suboptimal response.

Postintravitreal Injection Endophthalmitis: Incidence, Characteristics, Management, and Outcome.

Purpose: Postintravitreal injection (IVI) endophthalmitis is a rare but devastating complication. Herein, we report the incidence ,and clinical and microbiological characteristics, as well as the visual outcome, in IVIs endophthalmitis in two medical centers. Methods: All patients undergoing intravitreal injections between 1/2018 and 12/2019 in two large medical centers were analyzed for post-IVI endophthalmitis. Results: Of the total of 51,356 IVIs performed, 23 cases of post-IVI endophthalmitis were diagnosed, yielding an overall incidence of 0.045%. The median interval from IVI to symptoms onset was 2 days (IQR: 1-5). Cultures were positive in 56% of the cases (100% Gram-positive bacteria and 76% coagulase-negative staphylococcus). Parameters associated with higher culture-positive rates included samples taken during vitrectomy, WBC on vitreous smear, the number of IVIs in the 12 months prior to presentation, and the time interval from last IVI to diagnostic sampling. At 6- and 12-month follow-up, the median change in VA (logMAR) was -1.10 (IQR: (-1.32)-(-0.40)) and -1.02 (IQR: (-1.10)-(-0.30)), respectively. Younger age and better BCVA at presentation were associated with better VA outcome, while positive culture result and systemic steroids treatment were each associated with the worse visual outcome. We found no difference in visual outcomes between PPV and TAI as a primary procedure. Conclusion: Post-IVI endophthalmitis is a rare complication, and most patients do not regain their initial VA. Certain parameters (clinical, microbiological, and therapeutic) may help anticipate the outcome and guide decision making regarding diagnosis and treatment.

Retinal vascular occlusions in ocular Behçet disease - a comparative analysis.

PURPOSE: The literature on retinal vascular occlusions in Behçet disease (BD) patients is limited. The aim of this study is to thoroughly investigate retinal vascular occlusions among ocular BD patients. METHODS: Retrospective, multicentre case-control study. Three-hundred and three eyes of 175 patients with ocular BD, from 13 hospitals in Israel and Palestine, were included. Patients were assigned into two groups according to the presence of retinal vascular occlusion. Epidemiology, systemic and ocular manifestations, treatments and outcomes were compared between the groups and risk factors for retinal vascular occlusions were identified. RESULTS: One hundred twenty-five patients (71.4%) were male. The mean age at presentation was 28.2 ± 0.86 years. Retinal vascular occlusions were found in 80 eyes of 54 (30.9%) patients, including branch retinal vein occlusion (51.3%), peripheral vessels occlusions (32.5%), central retinal vein occlusion (13.8%) and arterial occlusions (7.5%). Systemic manifestations were similar among both groups. Anterior uveitis was more common in non-occlusive eyes (p < 0.01). Non-occlusive retinal vasculitis (p = 0.03) and ocular complications were more common in occlusive eyes (p < 0.01). Treatments including mycophenolate mofetil, Infliximab or a combination therapy of anti-metabolite and calcineurin inhibitor were more commonly used by occlusive patients (p < 0.05). Occlusive patients underwent more cataract surgeries (p = 0.03). The occlusive group had worse mean best-corrected visual acuity (BCVA) throughout follow-up (p < 0.01). Risk factors for retinal vascular occlusions included male sex and Jewish ethnicity (p < 0.05). CONCLUSION: Retinal vascular occlusions were found in a third of ocular BD patients. Occlusive eyes had a worse prognosis. Risk factors for vascular occlusions were identified.

Ocular Behçet Disease-Clinical Manifestations, Treatments and Outcomes According to Age at Disease Onset.

Behçet disease (BD) is a multisystemic disease that commonly involves the eyes. Although it affects patients in all age groups, data on ocular disease by age of onset are limited. This retrospective, multicenter study aimed to compare epidemiology, systemic and ocular manifestations, treatments and outcomes between three age groups: juvenile (<18 years), adult (18-39 years) and late (≥40 years) disease onset. The study included 175 ocular BD patients (303 eyes) from Israel and Palestine: juvenile-onset (n = 25, 14.3%), adult-onset (n = 120, 68.6%) and late-onset (n = 30, 17.1%). Most patients in all groups were male. Systemic manifestations were similar in all groups. Systemic co-morbidities were more common in late-onset patients. Bilateral panuveitis was the most common ocular manifestation in all patients. Non-occlusive retinal vasculitis, peripheral vessel occlusions, cataract and elevated intraocular pressure were found more commonly among juvenile-onset eyes. Anterior uveitis and macular ischemia were most common among late-onset eyes, while branch retinal vein occlusion was most common in adult and late-onset eyes. All patients were treated with corticosteroids. Methotrexate, immunomodulatory combinations and biologic treatments were more commonly used for juvenile-onset patients. All groups had a similar visual outcome. Our study showed that patients with ocular BD have varied ocular manifestations and require different treatments according to age of disease onset, but visual outcome is similar.

An Elderly Man with Atypical Multiple Evanescent White Dot Syndrome.

A rare occurrence of an atypical case of multiple evanescent white dot syndrome (MEWDS) in a 75-year-old man without viral prodrome or white dots on fundus that presented with acute, severe left eye visual loss, which returned to baseline without treatment in several weeks. Multimodal imaging, including fluorescein angiography (FA), fundus autofluorescence (FAF), indocyanine green angiography (ICG), and optical coherence tomography (OCT) demonstrated classical presentation of MEWDS with wreath-like lesions and inflammatory foci in the retinal pigment epithelium that correlated among modalities. Possible underlying systemic disorders were ruled out through extended work up. To the best of our knowledge, this is the first report to show atypical MEWDS in an elderly man with classic changes on FA, FAF, ICG, and OCT.

Evaluation of a self-imaging SD-OCT system designed for remote home monitoring.

PURPOSE: To compare identification rates of retinal fluid of the Notal Vision Home Optical Coherence Tomography (OCT) device (NVHO) when used by people with age-related macular degeneration (AMD) to those captured by a commercial OCT. METHODS: Prospective, cross-sectional study where patients underwent commercial OCT imaging followed by self-imaging with either the NVHO 2.5 or the NVHO 3 in clinic setting. Outcomes included patients' ability to acquire analyzable OCT images with the NVHO and to compare those with commercial images. RESULTS: Successful images were acquired with the NVHO 2.5 in 469/531 eyes (88%) in 264/290 subjects (91%) with the mean (SD) age of 78.8 (8.8); 153 (58%) were female with median visual acuity (VA) of 20/40. In the NVHO 3 cohort, 69 eyes of 45 subjects (93%) completed the self-imaging. Higher rates of successful imaging were found in eyes with VA ≥ 20/320. Positive percent agreement/negative percent agreement for detecting the presence of subretinal and/or intraretinal fluid when reviewing for fluid in three repeated volume scans were 97%/95%, respectively for the NVHO v3. CONCLUSION: Self-testing with the NVHO can produce high quality images suitable for fluid identification by human graders, suggesting the device may be able to complement standard-of-care clinical assessments and treatments.

UVEITIS AFTER THE BNT162b2 mRNA VACCINATION AGAINST SARS-CoV-2 INFECTION: A Possible Association.

PURPOSE: To describe uveitis cases after the BNT162b2 mRNA SARS-CoV-2 vaccination. METHODS: This is a multicenter, retrospective study. Vaccine-related uveitis diagnosis was supported by the classification of the World Health Organization Adverse Drug Terminology and the Naranjo criteria. RESULTS: Twenty-one patients (23 eyes) with a mean age of 51.3 years (23-78 years) were included. Eight of the 21 patients had a known history of uveitis. The median time from previous to current attack was 1 year (0.5-15 years). There were 21 anterior uveitis cases, two with bilateral inflammation. Eight cases occurred after the first vaccination and 13 after the second vaccination. All but three presented as mild to moderate disease. Two patients developed multiple evanescent white dot syndrome after the second vaccination. The mean time from vaccination to uveitis onset was 7.5 ± 7.3 days (1-30 days). At final follow-up, complete resolution was achieved in all but two eyes, which showed significant improvement. One case of severe anterior uveitis developed vitritis and macular edema after the second vaccination, which completely resolved after an intravitreal dexamethasone injection. CONCLUSION: Uveitis may develop after the administration of the BNT162b2 mRNA vaccine. The most common complication was mild to moderate anterior uveitis, while multiple evanescent white dot syndrome can also occur less frequently.

Endogenous fungal endophthalmitis: risk factors, clinical course, and visual outcome in 13 patients.

AIM: To analyze the risk factors, ophthalmological features, treatment modalities and their effect on the visual outcome in patients with endogenous fungal endophthalmitis (EFE). METHODS: Data retrieved from the medical files included age at presentation to the uveitis clinic, gender, ocular symptoms and their duration before presentation, history of fever, eye affected, anatomical diagnosis and laboratory evidence of fungal infection. Medical therapy recorded included systemic antifungal therapy and its duration, use of intravitreal antifungal agents and use of oral/intravitreal steroids. Surgical procedures and the data of ophthalmologic examination at presentation and at last follow-up were also collected. RESULTS: Included were 13 patients (20 eyes, mean age 58y). Ten patients presented after gastrointestinal or urological interventions and two presented after organ transplantation. In one patient, there was no history of previous intervention. Diagnostic vitrectomy was performed in 16 eyes (80%) and vitreous cultures were positive in 10 of the vitrectomized eyes (62.5%). In only 4 patients (31%), blood cultures were positive. All patients received systemic antifungal therapy. Sixteen eyes (80%) received intravitreal antifungal agent with voriconazole being the most commonly used. Visual acuity (VA) improved from 0.9±0.9 at initial exam to 0.5±0.8 logMAR at last follow-up (P=0.03). A trend of greater visual improvement was noted in favor of eyes treated with oral steroids (±intravitreal dexamethasone) than eyes that were not treated with steroids. The most common complication was maculopathy. Twelve eyes (60%) showed no ocular complications. CONCLUSION: High index of suspicion in patients with inciting risk factors is essential because of the low yield of blood cultures and the good general condition of patients at presentation. Visual prognosis is improved with the prompt institution of systemic and intravitreal pharmacotherapy and the immediate surgical intervention. Oral±local steroids could be considered in cases of prolonged or marked inflammatory responses in order to hasten control of inflammation and limit ocular complications.

Prospective, Longitudinal Pilot Study: Daily Self-Imaging with Patient-Operated Home OCT in Neovascular Age-Related Macular Degeneration.

Purpose: To evaluate longitudinally the performance of the Notal Vision Home OCT (NVHO), comprising a spectral-domain OCT device for patient self-imaging at home, telemedicine infrastructure for automated data upload, and deep learning algorithm for automated OCT evaluation. The aims were to study the system's performance in daily image acquisition and automated analysis and to characterize the dynamics of retinal fluid exudation in neovascular age-related macular degeneration (nAMD). Design: Pilot prospective, observational longitudinal study. Participants: Four individuals (mean age, 73.8 years) with nAMD (one or both eyes) undergoing anti-vascular endothelial growth factor therapy in routine clinical practice. Methods: The participants performed daily self-imaging at home with the NVHO for 1 month. The macular cube scans were uploaded automatically to the Notal Health Cloud. They underwent evaluation separately by the Notal OCT Analyzer (NOA) and human expert graders for fluid presence, segmentation, and volume. Main Outcome Measures: Daily self-imaging completion, image quality, acquisition time, agreement between automated and human grading of retinal fluid, and temporal dynamics of fluid volume. Results: Of 240 self-imaging attempts initiated, the number successfully completed was 211 (87.9%). Of these, 97.6% had satisfactory quality. For fluid presence, the NOA agreed with human grading in 94.7% of cases. From a subset of 24 scans with fluid, for agreement between NOA and human fluid volume measurements, the correlation coefficient was 0.996 and mean absolute difference was 1.5 nl (vs. 0.995 and 1.2 nl, respectively, for interhuman agreement). Graphic plots of fluid volume revealed wide variation in the dynamics of fluid exudation and treatment response. Conclusions: The participants could perform daily self-imaging at home and generate macular cube scans of satisfactory quality. Automated quantitative OCT analysis achieved high agreement with human grading. Daily self-imaging with automated OCT analysis permitted detailed characterization of the dynamics of fluid exudation and revealed wide variation between eyes. Metrics describing these dynamics may become important disease biomarkers. Home OCT telemedicine systems represent an alternative paradigm of disease monitoring; they may allow highly personalized retreatment decisions, with fewer unnecessary injections and clinic visits.

The Clinical Characteristics of Unilateral Placoid Pigment Epitheliopathies.

Purpose: Placoid-pigment-epitheliopathies like Acute-Posterior-Multifocal-Placoid-Pigment Epitheliopathy (APMPPE) and Relentless-Placoid-Choroidopathy (RPC) usually show bilateral involvement. This retrospective case series describes the clinical features with unilateral disease onset.Methods: 21 patients from 9 tertiary referring institutions were collected and evaluated.Results: Seventeen patients were included: 11 (65%) had unilateral placoid-pigment-epitheliopathy consistent with APMPPE, 6 (35%) with RPC (mean age: 28.82 ± 9.1 years). Mean follow-up time was 45 ± 48 months. Forty-one percent fellow-eyes had initial inflammatory signs including vitreous-cells, vascular-sheathing, and ONH swelling. Thirty-five percent developed chorioretinal lesions during follow-up after 19.5 ± 16.9 months. Initial inflammation in fellow-eye was not associated with fellow-eye involvement (p = .5). However, subfoveal choroidal-thickness (SCT) at baseline was significantly thicker in fellow-eyes who developed chorioretinal lesion compared to fellow-eyes who did not (400 ± 70 µm versus 283 ± 127 µm,p = .047).Conclusion: Unaffected fellow-eyes may have inflammatory signs at initial disease-onset and may develop lesions over time. They should be carefully monitored, particularly if they present with an increased SCT.

A 12-month prospective study to evaluate the efficacy of using the treat-and-extend regimen with intravitreal aflibercept as a Second-Line Treatment for Diabetic Macular Oedema (the TADI Study).

PURPOSE: To evaluate the efficacy of intravitreal aflibercept as a second-line therapy in eyes with persistent diabetic macular oedema (DMO) despite receiving initial bevacizumab treatment. METHODS: A prospective multicentre study was conducted in nine academic clinics in Israel. Starting from the first follow-up visit, a treat-and-extend regimen was applied in which the treatment intervals were extended by 2 weeks based on macular thickness using SD-OCT. The primary outcome was central subfield thickness (CST) at week 52. RESULTS: Forty-four patients (n = 48 eyes) were recruited to the study, and 43 eyes completed 52 weeks of follow-up. Patients received a mean (±SD) of 7.9 ± 3.5 bevacizumab injections before enrolment. The mean (±SD) CST under aflibercept therapy decreased from 468 ± 131 µm at baseline to 303 ± 67 µm at 52 weeks (p = 0.002), and best corrected visual acuity improved from 64 ± 15 ETDRS letters at baseline to 75 ± 8 letters at week 52 (p = 0.001). Twenty (46%) eyes met the treat-and-extend criteria and received a mean (±SD) of 10.9 ± 2 aflibercept injections. CONCLUSIONS: Eyes with persistent DMO following initial bevacizumab therapy had a marked reduction in macular thickness and improved visual acuity following 1 year of treatment with intravitreal aflibercept. Less than half of the patients met eligibility criteria for extension of the treatment interval; for these patients, the treat-and-extend regimen resulted in a maximum treatment interval of 10 weeks during the first year.

Demographic and Clinical Features of Pediatric Uveitis in Israel.

Purpose: To report the epidemiology, etiology, ocular characteristics, treatment and visual outcome of pediatric uveitis in Israel.Methods: Retrospective study from two tertiary uveitis centers.Results: Included were 107 patients (182 eyes), 55% females. Mean age at diagnosis 8.8 years. Uveitis was predominantly anterior, idiopathic, bilateral, and chronic. Systemic associations were seen in 36% of patients of which the most common disease was juvenile idiopathic arthritis. Infectious uveitis accounted for 37% of posterior uveitis cases of which toxoplasmosis was the most common cause. Anterior segment complications were commonly observed at presentation (41%); the most predominant were posterior synechiae, cataract, and band keratopathy. The most common posterior segment complications were papillitis, epiretinal membrane, and macular atrophy/scar. Ninety-three percent of eyes had visual acuity >20/40 at last follow-up.Conclusion: The pattern of pediatric uveitis in Israel is similar to that in the western world. Visual outcome was good in most eyes.

A NOVEL FINDING OF HYPERREFLECTIVE MATERIAL IN THE SILICONE-RETINA INTERFACE: An Optical Coherence Tomographic and Histopathological Study.

PURPOSE: To describe novel findings of hyperreflective material in the silicone-retina interphase on spectral domain optical coherence tomography (SD-OCT) imaging in eyes with silicone oil tamponade. METHODS: Retrospective observational clinical study of consecutive patients who underwent primary pars plana vitrectomy with silicone oil tamponade for rhegmatogenous retinal detachment. Repeat clinical examination and spectral domain optical coherence tomography macular imaging performed 3 months after surgery were evaluated to identify any macular pathologies, including formation of epiretinal membranes, intraretinal changes, subretinal fluid, and edema before scheduled secondary vitrectomy for silicone oil removal. RESULTS: Eighty-two patients (mean age 54 years, range 22-89) were included. Twelve eyes (14%) showed discrete preretinal hyperreflective organized coarse material in the silicone-retina interphase on spectral domain optical coherence tomography. The material was scattered in the posterior pole, with several foci showing additional hyperreflectivity of the inner retinal layers beneath. These findings did not resemble silicone oil emulsification in size, shape, or reflectivity. CONCLUSION: This is the first report on hyperreflective material detected by spectral domain optical coherence tomography in the silicone-retina interphase in eyes with silicone oil tamponade. These findings may represent an inflammatory response to silicone oil exposure that may be the initial manifestation of a future proliferative process, warranting a rigorous follow-up protocol for affected patients.

Aminobisphosphonate-associated orbital and ocular inflammatory disease.

PURPOSE: Aminobisphosphonates may cause orbital/ocular inflammation. Awareness of the clinical presentation and disease course is crucial. The purpose of this study was to analyse demographics, clinical presentation, disease course and treatment of aminobisphosphonate-associated orbital/ocular inflammation in a large series of patients. METHODS: A retrospective study of patients with aminobisphosphonate-associated orbital/ocular inflammation and a literature review to differentiate disease presentation and course between various aminobisphosphonates. RESULTS: Eight patients from our institution (6 women and 2 men, median age 62 years) were included. The used drugs were zoledronate, alendronate and risedronate. The most common clinical presentation was conjunctival hyperaemia/chemosis. Scleritis was the most common manifestation, followed by diffuse orbital inflammation and anterior uveitis. Ultrasound aided in diagnosis in all our patients. The aminobisphosphonate was halted in all patients, and some patients had anti-inflammatory treatment. Literature review included 68 patients (83 eyes), of them the most abundant drugs causing orbital/ocular inflammation were pamidronate (38 eyes) and zoledronate (35 eyes). Overall, among 76 patients, all drugs induced orbital disease, while uveitis was induced mostly by zoledronate and pamidronate, less by alendronate and not found among risedronate users. Time interval from drug administration to symptoms was hours to 28 days. Resolution was achieved in all patients, after 1-60 days from disease presentation, and the longer resolution period was found among alendronate users. CONCLUSION: Orbital/ocular inflammation was mostly caused by intravenous aminobisphosphonates. Uveitis was not induced by risedronate. The putative aminobisphosphonate should be halted at the onset of orbital/ocular involvement and prognosis is favourable.

Diabetic macular edema treated with ranibizumab following bevacizumab failure in Israel (DERBI study).

PURPOSE:: To evaluate the outcome of second-line intravitreal ranibizumab treatment in eyes with diabetic macular edema having persistent edema following initial therapy with intravitreal bevacizumab. METHODS:: Diabetic macular edema treated with ranibizumab following bevacizumab failure in Israel was a retrospective, multi-center study. Consecutive eyes with persistent diabetic macular edema following at least three previous intravitreal bevacizumab injections prior to intravitreal ranibizumab, at least three-monthly intravitreal ranibizumab injections and at least 12 months of follow-up were included. Data collected included demographics, ocular findings, diabetes control, details of intravitreal bevacizumab and ranibizumab injections, and visual and anatomical measurements before and after intravitreal ranibizumab treatment. RESULTS:: In total, 202 eyes of 162 patients treated at 11 medical centers across Israel were included. Patients received a mean (±standard deviation) of 8.8 ± 4.9 intravitreal bevacizumab injections prior to the switch to intravitreal ranibizumab. A mean of 7.0 ± 2.7 intravitreal ranibizumab injections were given during the 12 months following the switch to intravitreal ranibizumab. The median central subfield retinal thickness (±interquartile range) by spectral-domain optical coherence tomography decreased from 436 ± 162 µm at baseline to 319 ± 113 µm at month 12 (p < 0.001). Median logMAR visual acuity (±interquartile range) improved from 0.40 ± 0.48 at baseline to 0.38 ± 0.40 at month 12 (p = 0.001). Linear regression suggested that higher number of intravitreal ranibizumab injections and higher pre-switch central subfield retinal thickness were associated with favorable visual outcome. Higher number of intravitreal bevacizumab injections and the presence of intraretinal fluid before the switch lessened the odds of favorable outcome. CONCLUSION:: Switching from bevacizumab to ranibizumab in persistent diabetic macular edema was associated with anatomical improvement in the majority of eyes and ⩾2 lines of vision improvement in 22% of eyes.

The great imitator on the rise: ocular and optic nerve manifestations in patients with newly diagnosed syphilis.

PURPOSE: Ocular manifestations of syphilis have been reported in 2-10% of systemic infection. The purpose of this study was to report the incidence of ocular syphilis and various ocular manifestations, particularly optic nerve involvement, in newly diagnosed cases. METHODS: This was a retrospective study. Medical records of newly diagnosed syphilis patients between January 2009 and January 2017 in a tertiary medical centre were reviewed. RESULTS: There were 123 new systemic syphilis cases out of 569,222 (0.02%) admissions to the Tel Aviv Medical Center during the study period. Ninety-three of the 123 patients (76%) underwent ophthalmological examination. Twenty-three of the 93 patients (25%, mean age 48.6 ± 12.9 years, 20 males) had ocular syphilis, and in 12/23 (52%) patients, the ocular symptoms and findings prompted syphilis investigation. Eighteen of the 23 (78%) had optic nerve involvement, and the most common was inflammatory disc oedema. Older age (p = 0.0005) and tertiary stage disease (p = 0.0441) were associated with ocular manifestations and the presence of optic nerve findings. Human immunodeficiency virus (HIV) was associated with ocular but not optic nerve findings. Treatment included intravenous penicillin G, and four patients with severe optic neuropathy were also treated with systemic corticosteroids. Visual acuity significantly improved in most patients (p < 0.05). CONCLUSION: Ocular syphilis was found in one-quarter of the patients diagnosed with systemic syphilis and preceded the diagnosis of systemic disease in one-half of them. Optic nerve involvement was a common manifestation. A high index of suspicion for Treponema infection is required in patients presenting with optic nerve involvement to facilitate prompt diagnosis and treatment. Post-treatment visual outcome was good.

Herpetic Anterior Uveitis - Analysis of Presumed and PCR Proven Cases.

PURPOSE: To describe the demographics and clinical characteristics of patients with herpetic anterior uveitis (HAU), and compare characteristics by pathogen, recurrence, and association to iris atrophy. METHODS: Multicenter, retrospective study of AU patients diagnosed clinically and by polymerase chain reaction (PCR). RESULTS: The study included 112 eyes in 109 patients: 54 (48.2%) HSV, 34 (30.4%) VZV, 2 (1.8%) CMV, and 22 (19.6%) unspecified diagnosis. HSV eyes, compared to VZV, had a higher recurrence rate, corneal involvement, KPs, iris atrophy, elevated IOP and posterior synechia (p < 0.05). VZV patients had more frequent immunomodulatory treatments and history of systemic herpetic disease (p < 0.05). Fifty-nine (52.7%) eyes had recurrent disease. Iris atrophy was associated with a higher prevalence of posterior synechia, dilated distorted pupil, and high IOP (p < 0.05). CONCLUSION: Different HAU-causing Herpesviridae produce common clinical findings; therefore, PCR should be used more often to confirm specific diagnosis. Iris atrophy was associated with more severe disease.

Noninfectious Inflammatory Response following Intravitreal Bevacizumab Injections: Description of a Cluster of Cases in Two Centers and a Review of the Literature.

PURPOSE: To report a cluster of high incidence of noninfectious inflammatory reaction shortly after bevacizumab injection. METHODS: Data were collected from medical records of consecutive patients who underwent bevacizumab injections and presented with acute uveitis within 1-4 days. RESULTS: All 7 patients were injected intravitreally with bevacizumab from different batches and presented with visual deterioration. One patient with anterior uveitis complained of pain. None had hypopyon. Three patients with vitritis underwent a vitreous tap with an intravitreal injection of vancomycin and ceftazidime for possible infectious endophthalmitis. All patients received intensive topical antibiotic drops and steroids, and the intraocular inflammation resolved completely within 1 month. Five patients continued to receive bevacizumab injections without recurrent episodes. CONCLUSIONS: Our series demonstrates an incidence of noninfectious inflammatory reaction shortly after bevacizumab injection that is higher than that reported in the literature. The cause is more likely the preparation process in the same compounding pharmacy.

Cat-scratch disease: ocular manifestations and treatment outcome.

PURPOSE: To characterize cat-scratch disease (CSD) ocular manifestations and visual outcome and evaluate the effect of systemic antibiotics and corticosteroids on final visual acuity (VA). METHODS: Multicentre retrospective cohort study. Medical records of 86 patients with ocular disease (107 eyes) of 3222 patients identified in a national CSD surveillance study were reviewed. RESULTS: Mean age was 35.1 ± 14.2 years. Median follow-up was 20 weeks (range 1-806 weeks). Of 94/107 (88%) eyes with swollen disc, 60 (64%) had neuroretinitis at presentation, 14 (15%) developed neuroretinitis during follow-up, and 20 (21%) were diagnosed with inflammatory disc oedema. Optic nerve head lesion, uveitis, optic neuropathy and retinal vessel occlusion were found in 43 (40%), 38 (36%), 34 (33%) and 8 (7%) eyes, respectively. Good VA (better than 20/40), moderate vision loss (20/40-20/200) and severe vision loss (worse than 20/200) were found in 26/79 (33%), 35/79 (44%) and 18/79 (23%) eyes at baseline and in 63/79 (80%), 11/79 (14%) and 5/79 (6%) eyes at final follow-up, respectively (p < 0.001). Significant VA improvement (defined as improvement of ≥3 Snellen lines at final follow-up compared to baseline) occurred in 12/24 (50%) eyes treated with antibiotics compared with 14/16 (88%) eyes treated with antibiotics and corticosteroids (p = 0.02). Multivariate logistic regression was suggestive of the same association (odds ratio 7.0; 95% CI 1.3-37.7; p = 0.024). CONCLUSION: Optic nerve head lesion is a common and unique manifestation of ocular CSD. Most patients improved and had final good VA. Combined antibiotics and corticosteroid treatment was associated with a better visual outcome.
