Demographic and Clinical Features of Pediatric Uveitis in Israel

Epidemiology of Uveitis from a Tertiary Referral Hospital in Bulgaria over a 13-Year Period

Objectives: The aim of this study was to establish the etiology of uveitis and to examine its relationship with anatomical localization, age, and gender. Methods: A prospective study on patients with uveitis was conducted over a 13-year period at the Department of Ophthalmology, University Hospital "St. George", Plovdiv, Bulgaria. Each case was diagnosed based on a comprehensive eye examination, a review of the systems, and additional laboratory and specialized examination methods. Patients were categorized into four groups based on the location of inflammation: anterior uveitis, intermediate uveitis, posterior uveitis, and panuveitis. Results: A total of 606 patients with uveitis were included in the study. The mean age of the study group was 46.5 ± 18.6 years. There was no statistically significant difference in gender distribution (p = 0.329). Anterior uveitis was the most dominant anatomical localization (p < 0.001). Cases with clarified etiology were significantly prevalent (p < 0.001). The most frequently identified etiology was HLA B27-associated uveitis (32.5%), followed by viral uveitis (16.8%). A significant correlation between etiology and anatomical localization was found (p < 0.001). The highest proportion (93%) of cases with clarified etiology was associated with posterior uveitis, while the lowest (39.7%) was linked to intermediate uveitis. Conclusions: We found that anterior uveitis was the most common anatomical localization, followed by intermediate uveitis. The disease is rare in childhood, while in elderly patients, there is an increase in idiopathic and viral uveitis cases. Our results provide valuable information about the most common etiologies of uveitis among the Bulgarian population.

Social Determinants of Health in Uveitis: A Literature Review

BACKGROUND

The uveitides are a group of intraocular inflammatory diseases which can lead to blindness without treatment. It has been shown that socioeconomic status, health literacy, and access to healthcare play a pivotal role in the prevalence, severity, and treatment outcomes in ophthalmic conditions. We review the current literature on the impact of social determinants of health (SDoH) in patients with uveitis.

METHODS

A systematic literature search was conducted utilizing PubMed, Google Scholar, and Embase databases in July 2024. Inclusion criteria included studies written in English, focusing on SDoH in patients with uveitis using the following keywords: "uveitis," "social determinants of health," "socioeconomic status," "education," "access to healthcare," "health literacy," "health disparities," "race/ethnicity," "gender," and "environmental factors." Case reports were excluded.

RESULTS

Fifty two articles were included. Among these, 31 addressed healthcare access (e.g. limited specialist availability, cost/insurance barriers, urban-rural gaps), 23 highlighted economic stability (e.g. low income, out-of-pocket costs, poor medication adherence), 19 discussed environment and community (e.g. higher infectious uveitis rates in resource-limited areas, lack of social support), 18 focused on racial and ethnic disparities (e.g. advanced disease at presentation, worse outcomes for African American, Hispanic, and Indigenous populations), and 15 addressed education and awareness (e.g. low health literacy, inadequate patient education materials). Nine papers examined two domains, and 10 incorporated three or more. Across domains, limited resources and knowledge were associated with delayed diagnosis, suboptimal adherence, and poorer visual outcomes.

CONCLUSION

The current literature shows a correlation between SDoH and an increased incidence and poorer disease outcomes in patients with uveitis. Further research is needed to mitigate disparities in care for patients with uveitis.

Serum angiotensin-converting enzyme has low diagnostic value for pediatric sarcoid uveitis

PURPOSE

Sarcoid uveitis is rare in the pediatric population. Early diagnosis is challenging and is crucial, due to more severe complications. Diagnosis relies on various criteria, including elevated angiotensin-converting enzyme (ACE) levels. The objective of this study was to evaluate the diagnostic value of serum ACE levels in the diagnosis of pediatric sarcoid uveitis.

METHODS

This was an observational retrospective multicenter study of chronic, severe pediatric uveitis between 2013 and 2019 in two French tertiary referral centers.

RESULTS

An ACE assay result was available for 105 patients. Nine patients were diagnosed with sarcoid uveitis. The diagnostic values were as follows: sensitivity=22.2%, specificity=87.5%, positive predictive value=14.3%, negative predictive value=92.3%, positive likelihood ratio=1.8, and negative likelihood ratio=0.9.

CONCLUSION

The diagnostic performance of ACE in pediatric sarcoid uveitis was found to be poor. NPV exceeded 90% but was based on a significant number of false negatives, indicating a high risk of misdiagnosis. Likelihood ratios confirmed the limited diagnostic value of ACE. Considering age groups and clinical manifestations may enhance precision but requires larger studies. Serum ACE used as a diagnostic marker in pediatric sarcoid uveitis warrants caution and should be interpreted alongside other factors.

Clinical profile and treatment outcomes in pediatric uveitis - A series from South India

PURPOSE

The purpose of the study was to look at the clinical spectrum, treatment options, and visual outcomes in a large cohort of pediatric uveitis from a tertiary eye care center in South India.

METHODS

This is a retrospective study carried out at a tertiary eye center in South India. Cases of pediatric uveitis between January 2012 and June 2022 were retrieved from the hospital's medical database. Uveitis was classified according to the Standardization of Uveitis Nomenclature criteria. Demographic details, clinical presentation, complications, medical and surgical management, and visual outcome were evaluated.

RESULTS

Two hundred and six eyes of 132 cases were included, with a median age of 12 years. The male to female ratio was 1:1. Bilaterality was seen in 63.1% of cases. The mean duration of uveitis was 11.5 ± 18.5 months, and the mean follow-up period was 20.5 ± 25.1 months. Noninfectious uveitis was seen in 70.45% cases. Most common etiology in the noninfectious group was idiopathic (27.3%), while in the infectious group, it was tuberculosis (TB; 14.4%). Immunomodulators were used in 43.9% and biologics in 10.9% of cases. Most common complications were cataract (25.24%) and posterior synechiae (21.35%). Surgical procedures were done in 12.62%. The mean visual acuity was 0.81 ± 1.14 log of minimum angle of resolution (logMAR) at presentation and 0.49 ± 0.87 logMAR at the end of the study ( P = 0.002).

CONCLUSION

Pediatric uveitis poses a challenge in comparison to adult uveitis. Our study highlights the need for early diagnosis and aggressive management to prevent sequelae. Multidisciplinary approach is a key in improving the overall visual prognosis.

Retinal vessel density and choroidal flow changes in oligoarticular juvenile idiopathic arthritis with and without uveitis

PURPOSE

This cross-sectional optical coherence tomography angiography (OCTA) study aimed to assess the macular and optic nerve head (ONH) vascular density, foveal avascular zone, and outer retina and choriocapillaris flow in oligoarticular juvenile idiopathic arthritis (oJIA).

STUDY DESIGN

Prospective.

METHODS

Twenty-two eyes of 22 oJIA patients with uveitis (oJIA-U), 20 eyes of 20 oJIA patients without uveitis (isolated oJIA), and 26 healthy volunteers of similar ages and sexes were investigated. The superficial capillary plexus (SCP) and deep capillary plexus (DCP), ONH, foveal avascular zone (FAZ) parameters, the flow area of the outer retina, and choriocapillaris were evaluated.

RESULTS

Compared with the control group, both the oJIA-U group and isolated oJIA group showed significantly decreased vessel density of parafovea (p = 0.031 and p = 0.047, respectively) in DCP. Choriocapillaris flow area at 1 mm radius was significantly lower in the oJIA-U group compared to the control group (p = 0.001). Choriocapillaris flow area at 2- and 3-mm radius were significantly lower in the oJIA-U group compared to the control group (p < 0.001, for both) and isolated oJIA-U group compared to the control group (p = 0.008 and p = 0.001, respectively). The VD and thickness parameters of SCP and ONH, FAZ, and outer retina flow area were similar between the groups.

CONCLUSIONS

oJIA patients with and without uveitis revealed a decreased vessel density in the deep parafoveal region and choriocapillaris flow. Our findings suggest that retinal choroidal microvascular changes could be evident in oJIA-U patients without posterior segment involvement as well as oJIA patients without uveitis.

Epidemiology of Pediatric Uveitis in Argentina

PURPOSE

To explore the geographic variability of the epidemiology of pediatric uveitis, which, although rare in children, carries a significant risk of morbidity.

METHODS

This was a retrospective review conducted at two tertiary referral centers in Buenos Aires, Argentina. Demographic and clinical data of patients younger than 16 years diagnosed as having uveitis between January 1, 2006 and October 1, 2014 were collected.

RESULTS

A total of 257 patients (380 eyes) were included in the study. Cases tended to be unilateral (134, 52.1%), granulomatous (146, 56.8%), and localized to the posterior segment (121, 47.1%). Toxoplasmosis was the most common etiology (98, 38.1%).

DISCUSSION

The spectrum of pediatric uveitis in Buenos Aires most closely resembles that of Colombia. Understanding these geographic variations is important to aid providers who are caring for children in an increasingly globalized world. [J Pediatr Ophthalmol Strabismus. 2024;61(3):183-187.].

Childhood Chronic Idiopathic Uveitis in a Multicentre International Cohort

IMPORTANCE

Idiopathic uveitis makes up around 50% of non-infectious uveitis but the clinical characteristics in children are poorly understood.

OBJECTIVE

To report the demographic, clinical characteristics, and outcomes of children with idiopathic non-infectious uveitis (iNIU) in a multicentric retrospective study.

RESULTS

There were 126 (61 female) children with iNIU. The median age at diagnosis was 9.3 years (3-16 years) . Uveitis was bilateral in 106 patients and anterior in 68.At onset,impaired visual acuity and blindness in the worse eye were reported, in 24.4% and 15.1% patients but at 3 years of follow-up, there was a significant improvement in visual acuity (mean 0.11 SD ±0.50 vs 0.42 SD ± 0.59 p < .001).

CONCLUSIONS AND RELEVANCE

There is a high rate of visual impairment at presentation in children with idiopathic uveitis. The majority of patients have a significant improvement in vision, but 1 in 6 had impaired vision or blindness in their worse eye at 3 years.

Epidemiology of Pediatric Uveitis

Uveitis is uncommon in children and its diagnosis and treatment are challenging. Little is known of the epidemiology of pediatric uveitis. Indeed, population-based studies in the literature are rare. However, there are many tertiary referral center reports that describe the patterns of uveitis in childhood, although few are from developed countries, and their comparison presents some issues. Anterior uveitis is the most frequent entity worldwide, especially in Western countries, where juvenile idiopathic arthritis is diffuse. Most cases of intermediate uveitis do not show any association with infectious or noninfectious systemic diseases. In low- and middle-income countries, posterior uveitis and panuveitis are prevalent due to the higher rates of infectious etiologies and systemic diseases such as Behçet disease and Vogt-Koyanagi-Harada disease. In recent decades, idiopathic uveitis rate has decreased thanks to diagnostic improvements.

Pediatric Uveitis in Turkey: The National Registry Report II

PURPOSE

To report demographic and clinical profiles of children with uveitis in theTurkishpopulation.

METHODS

The data of the pediatric uveitis cases in the nation wide uveitis database were analyzed.

RESULTS

The study included 697 eyes of 442 patients with a meanage of 10.8 ± 3.8 years. There were 333 patients (75.3%) with non-infectious uveitis and 69 patients (15.6%) with infectious uveitis. Pars planitis (20.1%) was leading clinical form followed by idiopathic cases with uveitis other than pars planitis (18.8%), juvenile idiopathic arthritis(JIA) related uveitis (12.4%), Behçet uveitis (9.3%) and toxoplasma retinochoroiditis (7.9%). Ocular involvement was unilateral in 187 patients (42.3%) and bilateral in 255 patients (57.7%). The most common anatomiclocation of uveitis was anterior uveitis (39.1%), followed by intermediate uveitis (29.4%), panuveitis (16.1%) and posterior uveitis (15.4%).

CONCLUSION

The most common systemic association was JIA in the younger children and Behçet disease in the older children.

Pediatric Non-Infectious Uveitis: Long-Term Outcomes and Complications

PURPOSE

To describe the long-term prevalence of ocular complications and visual prognosis in patients with pediatric uveitis.

METHODS

Demographics, etiology and location of uveitis, type of complications, treatment and visual outcomes were recorded in 296 children at first examination and at 1-, 2-, 3-, 5- and 10-year time points.

RESULTS

Αnterior uveitis represented 53.4% of cases, followed by intermediate (28.0%), posterior uveitis (11.1%) and panuveitis (7.4%). The leading diagnoses were idiopathic uveitis (31.1%), juvenile idiopathic arthritis (27.0%) and pars planitis (22.6%). Posterior synechiae was the most frequent complication of anterior uveitis and panuveitis, cystoid macular edema and disc edema of intermediate and posterior uveitis respectively. Posterior uveitis and panuveitis had more severe final vision loss (23.1% and 20% respectively).

CONCLUSIONS

This study provides clinical characteristics and main complications in a longitudinal long-term follow-up of a large non-infectious pediatric uveitis Greek population. Early diagnosis and close monitoring remain of fundamental importance.

Online support group for patients with inflammatory eye disease: Characterisation of members and assessment of benefits

BACKGROUND

Support groups in ophthalmology may be of utmost importance for patients and caregivers. We aimed to characterise members of an online support group for patients and parents of children with inflammatory eye disease and assess the members' expectations and perceived benefits.

METHODS

A survey based on a voluntary, anonymous web questionnaire was distributed to the members of the 'Lirot' association online support group. The questionnaire included demographic, ocular and systemic information, functional and psychosocial data, support group use patterns, expectations and perceived benefits. Analysis was done for patients and parents.

RESULTS

Out of 67 respondents, 43 (64%) were patients, and 24 (36%) were parents. Fifty-eight (88%) were women. The mean age of respondents was 42.9 ± 1.34 years. Anterior uveitis was the most common, and most patients had good visual acuity (<0.3 logMAR). Parents reported higher anxiety levels (p = 0.044) and a more significant effect of their child's disease on their general function (p = 0.005). Most members sought several experts' opinions, psychological treatments and alternative medicine. All members used the WhatsApp group, while only approximately half used Facebook (p < 0.001). Members' expectations were fulfilled for social support, a sense of shared experience and being able to help others, but not for receiving information (p < 0.001). All members reported being willing to recommend the group to others.

CONCLUSIONS

Support group participation benefited group members. We suggest that ophthalmologists encourage their inflammatory eye disease patients to use online support groups, which may significantly improve their well-being.

Challenges and management of childhood non-infectious chronic uveitis

INTRODUCTION

Childhood uveitis is a sight-threatening condition, because if not properly recognized and treated can lead to several ocular complications and blindness. It represents a real challenge not only from an etiologic/diagnostic point of view, but also for management and therapy.

AREAS COVERED

In this review we will discuss the main etiologies, the diagnostic approach, risk factors associated to childhood non-infectious uveitis (cNIU), and the difficulties in eye examination in childhood. Moreover, we will discuss the treatment of cNIU in term of therapeutic choice, timing of initiation and withdrawal.

EXPERT OPINION

Identification of specific diagnosis is mandatory to prevent severe complications, thus a thorough differential diagnosis is essential. Pediatric eye examination may be extremely challenging due to the scarce collaboration, but novel techniques and biomarkers will help in identify low grade of inflammation, eventually modify long-term outcomes. Once identified the appropriate diagnosis, recognition of children who may benefit of a systemic treatment is crucial. What, When and how long are the key questions to address in this field. Current evidence and future results of ongoing clinical trials will help in driving treatment. A proper ocular screening, not only in the context of systemic disease, should be discussed by experts.

Uveitis in children: Epidemiological, clinical and prognostic characteristics

PURPOSE

The purpose of this study is to describe the characteristics and prognostic factors of pediatric uveitis in a French university referral hospital.

METHODS

We performed a retrospective study of all cases of all pediatric uveitis seen at our institution over a 7-year period.

RESULTS

A total of 141 eyes of 86 children were included. The mean age was 10.7 years, and 61.6% were girls. The uveitis was bilateral in 64.0% of cases. Anterior uveitis (41.0%) and intermediate uveitis (32.0%) were the most frequent forms. The most frequent etiologies were idiopathic (27.9%), juvenile idiopathic arthritis (25.6%) and pars planitis (18.6%). During the follow-up period, systemic corticosteroids were received by 43.0% of children, immunosuppressive drugs by 31.4% and biological agents by 18.6%. At the final examination, complications were present in 67.0% of patients: 18.0% had cataracts, and 11.3% had intraocular hypertension. Posterior synechiae were present in 27.6% of eyes, optic disc edema in 10.5% and macular edema in 16.2%. At the last visit, visual acuity was better than 20/200 in 97.0% of cases. The presence of band keratopathy, cataract or glaucoma was an independent predictor of impaired visual outcomes at follow-up.

CONCLUSION

Juvenile idiopathic arthritis is one of the most frequent and severe pediatric uveitides. Close monitoring and early treatment could prevent complications.

The Pattern of Uveitis in a Pediatric Population at a Tertiary Center in Thailand

PURPOSE

To describe the clinical characteristics and longitudinal pattern of visual acuity (VA) of pediatric patients with uveitis at a tertiary center in Thailand.

METHODS

We retrospectively reviewed the records of children with uveitis ≤16 years who presented to the clinic between January 2010 and June 2020.

RESULTS

The mean age at onset was 9.1(±4.3) years; the main characteristics were chronic (64.4%), unilateral (68.6%), and panuveitis (39%). The common etiologies were ocular toxoplasmosis (11.9%), herpetic uveitis (10.2%), and ocular toxocariasis (6.8%). Further, 40% of the eyes presented with VA of ≤20/200; mean VA at baseline improved from 0.93 to 0.72 logMAR at 3 months after presentation (P < .001), the baseline VA of ≤20/200 was significantly associated with poor VA outcome at 1 year.

CONCLUSION

Chronic, unilateral, and panuveitis represented the majority of our children with uveitis. Infectious etiology was common. Significant VA improvement can be achieved with optimum management.

Demographic and clinical features of pediatric uveitis and scleritis at a tertiary referral center in China

Background

To analyse demographic, clinical features, treatment and therapeutic outcomes of pediatric uveitis and scleritis patients.

Subjects

The clinical records of pediatric uveitis and scleritis cases between January 2012 and December 2020 at a tertiary uveitis service center in Tianjin Medical University Eye Hospital (TMUEH) were reviewed.

Results

In total, 209 patients (337 eyes) were included, 49.3% were male. The median onset age was 9.0 (IQR, 7.0–12.0) years. Chronic uveitis and scleritis accounted for 86.1%. Panuveitis (29.2%), anterior uveitis(29.2%), and intermediate uveitis (22.0%) were the most common presentations. The most common diagnoses were idiopathic (71.3%), JIA (8.1%), and infectious uveitis (4.8%). At baseline, 40.7% patients received oral corticosteroid therapy; during follow-up, corticosteroids (66.0%), disease-modifying antirheumatic drugs (61.2%), and biologic agents (35.4%) were the mainstay. Posterior synechia (26.1%) and cataracts (25.5%) were the most common complications. In acute cases, the median best corrected visual acuity (BCVA) was 0.99 (IQR, 0.5–1.0) at baseline and 0 (IQR, 0–0) at last follow-up; in chronic cases, the median BCVA improved from 1.09 (IQR, 0.5–2.0) to 0.27 (IQR, 0–0.5), with anterior chamber cell grade significantly declining. Ten eyes underwent cataract surgery during regular follow-up and achieved satisfactory long-term visual outcomes and decreased burden of immunosuppressants. The incidence of steroid-induced ocular hypertension was 41.0%, and children with frequent instillation of eyedrops were at high risk.

Conclusions

Most cases were of chronic uveitis and scleritis requiring long-term systemic immunosuppressive therapies in pediatric uveitis and scleritis in China. Good management of complications is important for long-term prognosis.

The Clinical Profile of Cat-Scratch Disease’s Neuro-Ophthalmological Effects

Cat-scratch disease is an illness caused by Bartonella henselae that occurs as a result of contact with an infected kitten or dog, such as a bite or scratch. It is more prevalent in children and young adults, as well as immunocompromised individuals. There are limited publications examining the features of CSD in patients. As such, the purpose of this research was to assess the clinical neuro-ophthalmological consequences of CSD reported in the literature. Among the ophthalmologic disorders caused by cat-scratch disease in humans, Parinaud oculoglandular syndrome, uveitis, vitritis, retinitis, retinochoroiditis and optic neuritis are the most prevalent. The neurological disorders caused by cat-scratch disease in humans include encephalopathy, transverse myelitis, radiculitis, and cerebellar ataxia. The current review addresses the neuro-ophthalmological clinical manifestations of cat-scratch disease, as described in papers published over the last four decades (1980–2022). All the data gathered were obtained from PubMed, Medline and Google Scholar. The current descriptive review summarizes the most-often-encountered clinical symptomatology in instances of cat-scratch disease with neurological and ocular invasion. Thus, the purpose of this review is to increase knowledge of cat-scratch disease’s neuro-ophthalmological manifestations.

Analysis of Clinical Characteristics of 52 Patients with Uveitis before and after Vitrectomy and Factors Affecting Clinical Efficacy

Objective

To investigate the pre- and postsurgical clinical characteristics and clinical efficacy of patients with uveitis.

Methods

The clinical data of patients with uveitis who underwent vitrectomy in our hospital from March 2019 to February 2021 were retrospectively analyzed. There were 52 cases of 64 eyes in total. The data on patient's gender, age, etiology, course of disease, anatomical classification, number of recurrences, changes in vision before and after surgery, changes in eye signs before and after surgery, and occurrence of postoperative complications were collected. The clinical features before and after vitrectomy were compared, and the influencing factors of clinical efficacy were analyzed.

Results

The ocular signs of patients with uveitis after vitrectomy were significantly improved compared with before operation, and the difference was statistically significant (P < 0.05). The visual acuity after vitrectomy in patients with uveitis was significantly improved compared with that before operation, and the difference was statistically significant (P < 0.05). There was no significant difference in the surgical treatment of uveitis patients of different gender, age, and etiology (P > 0.05). There are significant differences in the clinical efficacy of vitrectomy in patients with different anatomical classifications. Among them, patients with panuveitis have the best clinical efficacy with vitrectomy and patients with posterior uveitis have the worst clinical efficacy with vitrectomy (P < 0.05). There is a significant difference in the clinical efficacy of vitrectomy in patients with recurrence times. The lower the number of recurrences, the better the clinical efficacy of vitrectomy in patients (P < 0.05).

Conclusion

There are significant differences in the clinical signs of patients with uveitis before and after vitrectomy. Vitrectomy is effective in the treatment of uveitis. The type of anatomy and the number of recurrences are influencing factors for the clinical efficacy of vitrectomy. For patients with posterior uveitis, the surgical method should be carefully considered or a more reasonable treatment method should be selected, and for patients with uveitis with less recurrence, vitrectomy should be considered for active treatment.

Assessment of systemic and ocular inflammation in juvenile idiopathic arthritis via choroidal vascularity index

We aimed to evaluate the retina and the choroid in children with juvenile idiopathic arthritis (JIA) employing optical coherence tomography (OCT). This cross-sectional study, carried out between June 2017-December 2019, included JIA patients with (JIAU; n = 28) and without (JIAN; n = 65) uveitis and age-matched healthy controls (HC) (n = 102). Laboratory and demographic information of the children were obtained from hospital records. Activity of the disease was evaluated by the Juvenile Arthritis Disease Activity Score-71 (JADAS-71). Choroidal scans were obtained with spectral domain-OCT in enhanced-depth imaging (EDI)-OCT mode to assess choroidal thickness (ChT) at five locations (under the fovea, at 750 and 1500 μm nasal and temporal sections), luminal area (LA), stromal area (SA), total subfoveal choroidal area (TCA) and CVI (choroidal vascularity index). Central foveal thickness (CFT) and 1-mm diameter foveal thickness (FT) were calculated automatically through macular volume scan analysis. The choroid was significantly thicker in JIAU and JIAN patients than in HC at the subfoveal and at the 750N, 750T, 1500T points (p < 0.001, p = 0.009, p < 0.001, and p < 0.001, respectively). The CVI was lower in JIAU patients than in JIAN patients and HC (p = 0.02). Conversely, CFT was greater in JIAU patients as compared to the JIAN patients and HC (p = 0.02). Changes in chorioretinal OCT parameters in the absence of uveitis in JIA patients may reflect subclinical choroidal inflammation in these patients. Ophthalmologic examination, including choroidal imaging in a larger cohort, may clarify this aspect.

Chorio-retinal toxoplasmosis: treatment outcomes, lesion evolution and long-term follow-up in a single tertiary center

BACKGROUND

Ocular toxoplasmosis is a common cause of ocular inflammation worldwide. The aim of this study is to characterize the clinical outcomes and lesion evolution of patients with ocular toxoplasmosis and to compare the primary and reactivation subgroups.

METHODS

A retrospective population-based cohort study at one uveitis-specialized tertiary referral center. Patients presenting with active ocular toxoplasmosis between the years 2007-2016 were included. Primary ocular toxoplasmosis and reactivations were compared.

RESULTS

Included were 22 patients, 64% female with a mean age of 29 ± 18 years, 59% (n = 13) were primary, 9% (n = 2) congenital and 32% (n = 7) reactivations. Visual acuity improved from 0.38 ± 0.44 to 0.20 ± 0.27 LogMAR (P = 0.026) after a mean of 37 ± 33 months. Initial lesion size was 2.38 ± 1.1 optic disc areas, reducing to 1.56 ± 1.24 following 2 months (34% reduction, P = 0.028) and to 1.17 ± 0.87 disc areas following one year (51% reduction, P = 0.012). Patients with macula-threatening lesions had worse visual acuity (0.50 ± 0.46 vs. 0.05 ± 0.07 LogMAR, P = 0.047). Primary and reactivation subgroups had similar presentations, visual outcomes and recurrence rates (all P > 0.05).

CONCLUSIONS

In this population, primary ocular toxoplasmosis was the most common presentation. Lesion size reduced during the initial months with limited change thereafter and a third of cases recurred. Macula-threatening lesions were associated with worse visual acuity, and no significant differences were seen between the primary and reactivation subgroups.
