PURPOSE
Uveitis is the third leading cause of blindness worldwide. This study aimed to summarize the pattern of uveitis in Iran through a systematic review.
METHODS
This review was conducted according to the guidelines for systematic reviews in the following four steps: literature search, study selection and assessment, inclusion and exclusion criteria, and statistical analysis.
RESULTS
One hundred and fifteen articles were identified by an encyclopedic literature search, and three independent investigators examined them according to the defined inclusion and exclusion criteria. Eventually, 109 manuscripts were retrieved and six cross-sectional studies covering 3,567 patients were included and reviewed. According to the results, the mean age of patients was 40 years, and sex was not a statistically significant predisposing factor. The most common anatomical pattern of involvement was anterior uveitis, and the prevalence of the other three types of uveitis, including middle, posterior, and pan-uveitis, were almost equal. Overall, the most common etiologies of uveitis in the Iranian population were idiopathic uveitis, toxoplasmosis, Behcet's syndrome, and Fuchs heterochromic iridocyclitis.
CONCLUSION
This study depicted the pattern of uveitis in the Iranian society; this can help physicians in the diagnostic approach, management, and treatment of patients.

Meta-Analysis Review
PURPOSE
To critically assess the evidence base regarding outcomes following cataract surgery in uveitic cases.
DESIGN
Systematic evidence-based review and meta-analysis.
METHODS
A comprehensive search query was performed on MEDLINE, EMBASE, CINHAL, and CENTRAL databases. Relevant publications were identified by reviewing query results and reference list searches.
RESULTS
A total of 89 articles met eligibility criteria. Among uveitic eyes with quiet or mostly quiet uveitis before cataract surgery, 20/40 visual acuity or better (≥20/40) was achieved in 68% following phacoemulsification, 72% following extracapsular cataract extraction, and 40% following pars plana lensectomy. More eyes undergoing cataract surgery with intraocular lens (IOL) implantation than eyes left aphakic achieved ≥20/40 postoperatively (71% vs 52%). Eyes receiving acrylic IOLs or heparin-surface-modified (HSM) polymethylmethacrylate had better visual outcomes than those receiving non-HSM polymethylmethacrylate or silicone IOLs. Active uveitis at the time of cataract surgery was associated with worse visual outcomes. Compared with other uveitis cases, the proportion achieving 20/40 or better post cataract surgery was better for Fuchs heterochromic cyclitis cases and worse for uveitis related to Behçet disease, Vogt-Koyanagi-Harada disease, or sympathetic ophthalmia, and also posterior uveitis in general.
CONCLUSION
Cataract surgery in eyes with uveitis resulted in normal range levels of visual acuity in most cases. The review suggests that preoperative control of uveitis, use of an acrylic or HSM IOL, and a diagnosis of Fuchs heterochromic cyclitis were associated with better outcomes. Posterior-involving uveitides tended to do worse, likely because of vision-limiting complications of uveitis. Average results may not be applicable to specific clinical scenarios.

Meta-Analysis
BACKGROUND
Ocular toxoplasmosis (OT) is caused by the parasite Toxoplasma gondii. OT is the leading cause of posterior uveitis globally; it is a recurrent disease that may result in visual impairment and blindness. This systematic review and meta-analysis aim to summarize and evaluate the risk factors for recurrences, visual impairment, and blindness described in the literature worldwide.
METHODS AND FINDINGS
We performed a systematic literature search in PubMed, Embase, VHL, Cochrane Library, Scopus, and DANS EASY Archive. All studies reporting patients with clinically and serologically confirmed OT presenting any clinical or paraclinical factor influencing recurrences, visual impairment, and blindness were included. Studies presenting secondary data, case reports, and case series were excluded. An initial selection was made by title and abstract, and then the studies were reviewed by full text where the eligible studies were selected. Then, the risk of bias was assessed through validated tools. Data were extracted using a validated extraction format. Qualitative synthesis and quantitative analysis were done. This study was registered on PROSPERO (CRD42022327836).
RESULTS
Seventy two studies met the inclusion criteria. Fifty-three were summarized in the qualitative synthesis in three sections: clinical and environmental factors, parasite and host factors, and treatment-related factors. Of the 72 articles, 39 were included in the meta-analysis, of which 14 were conducted in South America, 13 in Europe, four in Asia, three multinational, two in North America and Central America, respectively, and only one in Africa. A total of 4,200 patients with OT were analyzed, mean age ranged from 7.3 to 65.1 year of age, with similar distribution by sex. The frequency of recurrences in patients with OT was 49% (95% CI 40%-58%), being more frequent in the South American population than in Europeans. Additionally, visual impairment was presented in 35% (95% CI 25%-48%) and blindness in 20% (95% CI 13%-30%) of eyes, with a similar predominance in South Americans than in Europeans. On the other hand, having lesions near the macula or adjacent to the optic nerve had an OR of 4.83 (95% CI; 2.72-8.59) for blindness, similar to having more than one recurrence that had an OR of 3.18 (95% CI; 1.59-6.38). Finally, the prophylactic therapy with Trimethoprim/Sulfamethoxazole versus the placebo showed a protective factor of 83% during the first year and 87% in the second year after treatment.
CONCLUSION
Our Systematic Review showed that clinical factors such as being older than 40 years, patients with de novo OT lesions or with less than one year after the first episode, macular area involvement, lesions greater than 1 disc diameter, congenital toxoplasmosis, and bilateral compromise had more risk of recurrences. Also, environmental and parasite factors such as precipitations, geographical region where the infection is acquired, and more virulent strains confer greater risk of recurrences. Therefore, patients with the above mentioned clinical, environmental, and parasite factors could benefit from using prophylactic therapy.

Meta-Analysis Review
OBJECTIVES
Children and adults may develop Behçet's disease (BD), often with ocular involvement such as uveitis. This study aimed to determine the prevalence and type of ocular manifestations in childhood and adult BD.
METHODS
Medline, Web of Science and Cochrane databases were searched from inception to October 5, 2018 to identify publications related to Behçet's disease comprising minimum twenty patients and providing the frequency of ocular manifestations (OC). Random effects models were used to combine the prevalence of OC in adults and children with BD. Heterogeneity was evaluated using I2.
RESULTS
The search resulted in 3129 articles, of which 51 were included in meta-analysis. OCs were slightly more frequent in childhood onset BD with the mean [95% Confidence Interval] frequency of 45 [34-56%] compared to 36 [29-43%] in adults, however, this difference was not statistically significant (p=0.198). In both children and adults, posterior uveitis (children 27% vs. adults 25%, and retinal vasculitis in adults 16%) was the most common ocular manifestation, followed by anterior uveitis (children 18% vs. adults 23%). When comparing the distribution of OC in Behcet's in adults, there was geographic variation where OC were higher in Turkey and the Middle East 42%, followed by Europe and North America (36%), North Africa 26% and East Asia 25% but not significantly (p=0.27).
CONCLUSIONS
Ocular manifestations, predominantly uveitis; are common in BD. Ocular manifestations are not proportionately more frequent in adults with BD along the ancient Silk Road.

Review
Early poor outcomes of intraocular inflammation (IOI) after intravitreal brolucizumab (IVB) have negatively affected the use of brolucizumab in clinical routine. We wished to identify factors related to the treatment details of IOI involving the posterior segment resulting from IVB for neovascular AMD (nAMD), if these were reported in detail. Articles were retrieved from PubMed, Scopus, ClinicalTrials, and CENTRAL using the following search terms:
AND AND . The risk of bias was rated using the JBI Critical Appraisal Tool. We included 31 reports (41 patients and 46 eyes). Patients were 75.9 ± 8.5 years, and 58.5% were female. IOI occurred 41.7 ± 37.5 (median 37.0) days after treatment initiation with 2.0 ± 1.3 (1-6) IVB injections. A mean change in visual acuity of -14.6 ± 21.0 (median -6.5) letters was reported. The mean time from first IOI signs to the initiation of any anti-inflammatory treatment was 3.3 ± 6.2 days, with 63% of the patients receiving systemic corticosteroids as standard treatment. Finally, a period effect was observed, with a change in visual acuity of -25.3 ± 27.1 and -2.6 ± 7.3 letters in the chronologically first and last third, respectively, of treated eyes (effect size: r = 0.71; = 0.006). Functional outcomes markedly improved with increasing experience in managing IOI. PubMed: 37510788

Meta-Analysis Review
BACKGROUND
Ocular toxoplasmosis (OT) is the most common cause of posterior uveitis, which leads to visual impairment in a large proportion of patients. Antibiotics and corticosteroids lower the risk of permanent visual loss by controlling infection and inflammation. However, there remains disagreement regarding optimal antibiotic therapy for OT. Therefore, this systematic review and meta-analysis were performed to determine the effects and safety of existing antibiotic treatment regimens for OT.
METHODS
MEDLINE, EMBASE, The Cochrane Central Register of Controlled Trials, LILACS, WHO International Clinical Trials Registry Platform portal, ClinicalTrials.gov, and Gray Literature in Europe ("OpenGrey") were searched for relevant studies; manual searches of reference lists were performed for studies identified by other methods. All published and unpublished randomized controlled trials that compared antibiotic schemes known to be effective in OT at any dosage, duration, and administration route were included. Studies comparing antibiotics with placebo were excluded. This review followed standard methodological procedures recommended by the Cochrane group.
RESULTS
Ten studies were included in the narrative summary, of which four were included for quantitative synthesis (meta-analysis). Interventions were organized into three groups: intravitreal clindamycin versus pyrimethamine + sulfadiazine, trimethoprim + sulfamethoxazole versus other antibiotics, and other interventions. The first comparison favored intravitreal clindamycin (Mean difference (MD) = 0.10 logMAR; 95% confidence interval = 0.01 to 0.22). However, this finding lacks clinical relevance. Other outcomes showed no statistically significant differences between the treatment groups. In general, the risk of performance bias was high in evaluated studies, and the quality of the evidence found was low to very low.
CONCLUSIONS
No antibiotic scheme was superior to others, and the selection of a treatment regimen depends on multiple factors; therefore, treatment should be chosen based on safety, sulfa allergies, and availability.

Meta-Analysis Review
BACKGROUND
Non-infectious intermediate uveitis, posterior uveitis and panuveitis are a heterogeneous group of inflammatory eye disorders. Management includes local and systemic corticosteroids, immunosuppressants and biological drugs.
OBJECTIVES
To evaluate the clinical effectiveness and cost-effectiveness of subcutaneous adalimumab (Humira; AbbVie Ltd, Maidenhead, UK) and a dexamethasone intravitreal implant (Ozurdex; Allergan Ltd, Marlow, UK) in adults with non-infectious intermediate uveitis, posterior uveitis or panuveitis.
DATA SOURCES
Electronic databases and clinical trials registries including MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and the World Health Organization's International Clinical Trials Registry Platform were searched to June 2016, with an update search carried out in October 2016.
REVIEW METHODS
Review methods followed published guidelines. A Markov model was developed to assess the cost-effectiveness of dexamethasone and adalimumab, each compared with current practice, from a NHS and Personal Social Services (PSS) perspective over a lifetime horizon, parameterised with published evidence. Costs and benefits were discounted at 3.5%. Substantial sensitivity analyses were undertaken.
RESULTS
Of the 134 full-text articles screened, three studies (four articles) were included in the clinical effectiveness review. Two randomised controlled trials (RCTs) [VISUAL I (active uveitis) and VISUAL II (inactive uveitis)] compared adalimumab with placebo, with limited standard care also provided in both arms. Time to treatment failure (reduced visual acuity, intraocular inflammation, new vascular lesions) was longer in the adalimumab group than in the placebo group, with a hazard ratio of 0.50 [95% confidence interval (CI) 0.36 to 0.70; < 0.001] in the VISUAL I trial and 0.57 (95% CI 0.39 to 0.84; = 0.004) in the VISUAL II trial. The adalimumab group showed a significantly greater improvement than the placebo group in the 25-item Visual Function Questionnaire (VFQ-25) composite score in the VISUAL I trial (mean difference 4.20; = 0.010) but not the VISUAL II trial (mean difference 2.12; = 0.16). Some systemic adverse effects occurred more frequently with adalimumab than with placebo. One RCT [HURON (active uveitis)] compared a single 0.7-mg dexamethasone implant against a sham procedure, with limited standard care also provided in both arms. Dexamethasone provided significant benefits over the sham procedure at 8 and 26 weeks in the percentage of patients with a vitreous haze score of zero ( < 0.014), the mean best corrected visual acuity improvement ( ≤ 0.002) and the percentage of patients with a ≥ 5-point improvement in VFQ-25 score ( < 0.05). Raised intraocular pressure and cataracts occurred more frequently with dexamethasone than with the sham procedure. The incremental cost-effectiveness ratio (ICER) for one dexamethasone implant in one eye for a combination of patients with unilateral and bilateral uveitis compared with limited current practice, as per the HURON trial, was estimated to be £19,509 per quality-adjusted life-year (QALY) gained. The ICER of adalimumab for patients with mainly bilateral uveitis compared with limited current practice, as per the VISUAL trials, was estimated to be £94,523 and £317,547 per QALY gained in active and inactive uveitis respectively. Sensitivity analyses suggested that the rate of blindness has the biggest impact on the model results. The interventions may be more cost-effective in populations in which there is a greater risk of blindness.
LIMITATIONS
The clinical trials did not fully reflect clinical practice. Thirteen additional studies of clinically relevant comparator treatments were identified; however, network meta-analysis was not feasible. The model results are highly uncertain because of the limited evidence base.
CONCLUSIONS
Two RCTs of systemic adalimumab and one RCT of a unilateral, single dexamethasone implant showed significant benefits over placebo or a sham procedure. The ICERs for adalimumab were estimated to be above generally accepted thresholds for cost-effectiveness. The cost-effectiveness of dexamethasone was estimated to fall below standard thresholds. However, there is substantial uncertainty around the model assumptions. In future work, primary research should compare dexamethasone and adalimumab with current treatments over the long term and in important subgroups and consider how short-term improvements relate to long-term effects on vision.

Review
OBJECTIVE
We conducted a systematic review to evaluate the outcome of macular hole (MH) treatment in eyes with uveitis.
DATA SOURCE
We searched PubMed and Embase databases from inception through August 15, 2021.
STUDY SELECTION
We included eyes with MHs secondary to uveitis that were managed medically or underwent pars plana vitrectomy (PPV). We excluded eyes with idiopathic MH and those secondary to causes other than uveitis.
RESULTS
Of 27 articles, we identified 86 eyes with MH secondary to uveitis that received either conservative medical treatment alone or PPV with adequate follow-up. The mean (± SD) age of patients included in this review was 46.6 (± 16.8) years; 60.5% were males. The most common etiology of uveitis was Behçet's disease (34.6%) and toxoplasmosis (19.7%). The most common anatomical location of uveitis was posterior (59.3%) followed by panuveitis (35.2%). The mean (± SD) baseline LogMAR vision was 1.1 (± 0.5). Conservative medical treatment was employed in 34.9%, while PPV was performed in 65.1% of eyes. Overall, the mean (SD) LogMAR vision improved from 1.1 (± 0.5) at baseline to 0.7 (± 0.5) after treatment. Inflammation-related MHs were closed in 40% of eyes after conservative therapy and in 87.5% of eyes after PPV. Visual improvement occurred in most eyes (83.9%) that had successful closure of their MH.
CONCLUSIONS
Visual improvement occurs in most eyes that had successful closure of their inflammation-related MH. Conservative medical control of uveitis may lead to closure of inflammation-related MHs and is an important step prior to surgery, if required. Surgical intervention for inflammation-related MHs is associated with good functional and anatomical results.

Current Pharmaceutical Design 2017Tobacco smoking has detrimental influence on human health. (Review)
Review
BACKGROUND
Tobacco smoking has detrimental influence on human health.
AIM
The analysis of influence of tobacco smoking on retina diseases, uveitis, optic neuropathies, and thyroidassociated orbitopathy in adults and children.
METHODS
A comprehensive review of the literature performed through MEDLINE and PubMed searches, covering the years 2000-2016.
RESULTS
In adults, tobacco smoking is a strong risk factor for age-related macular degeneration, polypoidal choroidal vasculopathy, uveitis and inflamed cystoid macular edema as well as Grave`s ophthalmopathy. Tobacco smoking reduces thickness of the retina and choroid, plays a role in episcleritis, sclerits, tobacco optic neuropathy, and Leber's hereditary optic neuropathy. In children, maternal smoking is a significant risk factor for stages 3 and 4 retinopathy of prematurity, optic nerve hypoplasia among babies with a birth weight over 2500 g and thinner retinal nerve fiber layer.
CONCLUSION
Tobacco smoking plays an important role in the pathogenesis of many posterior eye segment diseases leading to blindness in adults and children.

Efficacy and safety of immunomodulatory drugs in patients with non-infectious intermediate and posterior uveitis, panuveitis and macular edema: A systematic literature review.
BACKGROUND
Non-infectious non-anterior uveitis (NINA) is a sight-threatening condition that often requires immunomodulatory drugs (IMDs) for its management.
OBJECTIVES
To evaluate the published evidence regarding the use of IMDs in adult patients with NINA uveitis including intermediate (IU) and posterior uveitis (PU), panuveitis (PanU) and macular edema (ME).
METHODS
We performed a systematic literature review. Search strategies were designed for Medline, Embase, and Cochrane Libraries for articles up to 2019 to evaluate the efficacy and safety of the IMDs. A quality assessment was performed using the Jadad Scale.
RESULTS
Nineteen randomized clinical trials were selected from the 1,103 articles retrieved. Characteristics of patients, treatment dosages and outcome measures were heterogeneous. The outcomes most frequently analyzed were visual acuity (VA), macular thickness and vitreous haze (VH). Different IMDs were used at their usual dosages. Methotrexate (MTX), micophenolate mofetil, cyclosporine A (CsA), tacrolimus, adalimumab and sarilumab were effective in NINA uveitis. Rituximab combined with MTX was effective in PU. Interferon-β was superior to MTX, albeit with more adverse events in IU with ME. CsA was similar to cyclophosphamide (Cyc) in Behçet uveitis. Tacrolimus was safer and similar to CsA. Cyc was effective in serpiginoid choroiditis, but when combined with azathioprine in PU, but did not improve VA. Secukinumab did not prevent NINA uveitis recurrences, although intravenously it showed a higher response rate than when used subcutaneously. Daclizumab did not show any benefits in Behçet NINA uveitis.
CONCLUSION
Several IMDs and their combinations can be useful in treating NINA uveitis. The available studies were heterogeneous regarding patient characteristics and outcomes.
