RESUMO
BACKGROUND: To determine the prevalence, clinical characteristics, and independent predictors of uveitic macular edema (UME) in patients with intermediate, posterior and panuveitis. METHODS: We retrospectively reviewed the records of patients with intermediate, posterior, and panuveitis who underwent macular assessment using optical coherence tomography between January 2015 and February 2020. The prevalence of UME and clinical characteristics of the patients were described. Predictors of UME were identified using multivariate regression analysis. RESULTS: A total of 349 patients were included. The mean age was 41 years, female: male ratio was 1.3:1. The prevalence of UME was 51.9%. UME was found in 33.9%, 56.9%, and 54.1% of the intermediate, posterior, and panuveitis cases, respectively. Among patients with UME, 47% had infectious uveitis, 32.6% had idiopathic uveitis, and 20.4% had immune-mediated uveitis. Diffuse macular edema was the most frequently observed pattern (36.5%). Multivariate analysis showed that factors independently associated with UME included age at uveitis onset (adjusted odds ratio [aOR] 1.01, 95% confidence interval [CI] 1.00-1.03, P = 0.036), PU and panuveitis compared with intermediate uveitis (aOR 2.09, 95% CI 1.14-3.86, P = 0.018), and infectious uveitis compared with noninfectious uveitis (aOR 2.13, 95% CI 1.34-3.37, P = 0.001). CONCLUSIONS: Increasing age at uveitis onset, posterior/panuveitis, and infectious etiology are predictive factors for UME in patients with intermediate, posterior and panuveitis.

PURPOSE: To investigate for association between skin autofluorescence (SAF) advanced glycation end products (AGEs) and uveitis/scleritis activity in systemic inflammatory disease-related active non-infectious uveitis/scleritis patients. METHODS: This cross-sectional study was conducted at Siriraj Hospital during October 2019 to March 2020. AGEs were measured by SAF method in systemic immune-related disease patients with active uveitis/scleritis, and those results were compared with those of healthy age-matched controls. RESULTS: Thirty-one active non-infectious uveitis/scleritis patients and 31 age-matched controls were enrolled. The mean age of patients was 40.0 ± 12.8 years, and most were female (55.0%). The most common associated systemic immune-related disease was Vogt-Koyanagi-Harada disease (n = 14). Mean SAF AGE level in the study group compared to the control group was 2.38 ± 0.66 arbitrary units (AU) versus 2.58 ± 0.56 AU, respectively (p = 0.20). Multivariate analysis showed decreased SAF AGE level to be significantly associated with active ocular inflammation, (odds ratio: 0.01, 95% confidence interval: 0.00004-0.81; p = 0.04). CONCLUSIONS: SAF AGE level was not so far found to be a reliable biomarker for indicating uveitis/scleritis activity in systemic immune-related disease patients with active ocular inflammation.

BACKGROUND: Extranodal natural killer/T-cell lymphoma (ENKTL), nasal type, generally affects the orbit by direct extension. It can even rarely present as severe intraocular inflammation mimicking endophthalmitis. Delayed diagnosis and treatment are frequently reported. CASE PRESENTATION: A 43-year-old woman presented with 2-month blurred vision in her left eye. Ocular examination revealed hypopyon panuveitis. She was initially diagnosed with endogenous endophthalmitis, which proved irresponsive to antimicrobial therapy. High-dose prednisolone was given afterward, but this failed to stop the development and continuous progression of ocular inflammation. The diagnosis of ENKTL was finally confirmed from the pathological findings of oral ulcers and cervical lymph nodes and chemotherapy was prescribed. After the first cycle of chemotherapy, the patient's ocular inflammation subsided. Unfortunately, her left eye became phthisis with progressive visual loss within 9 months following the diagnosis. CONCLUSIONS: The diagnosis of intraocular ENKTL is frequently delayed, which can lead to severe problems for treatment as the disease is aggressive with a poor prognosis. It can be found not only in elderly patients but also in a middle-aged individual. In patients with ocular inflammation, a thorough systemic evaluation and histopathological examination of the associated systemic findings is extremely helpful and may reveal the cause of the ocular inflammation, including revealing possible ENKTL.

BACKGROUND: To report three cases of nontuberculous mycobacterial (NTM) endophthalmitis following multiple ocular surgeries and to review previous literature in order to study the clinical profile, treatment modalities, and visual outcomes among patients with NTM endophthalmitis. METHODS: Clinical manifestation and management of patients with NTM endophthalmitis in the Department of Ophthalmology, Faculty of Medicine, Siriraj hospital, Mahidol University, Bangkok, Thailand were described. In addition, a review of previously reported cases and case series from MEDLINE, EMBASE, and CENTRAL was performed. The clinical information and type of NTM from the previous studies and our cases were summarized. RESULTS: We reported three cases of NTM endophthalmitis caused by M. haemophilum, M. fortuitum and M. abscessus and a summarized review of 112 additional cases previously published. Of 115 patients, there were 101 exogenous endophthalmitis (87.8%) and 14 endogenous endophthalmitis (12.2%). The patients' age ranged from 13 to 89 years with mean of 60.5 ± 17.7 years with no gender predominance. Exogenous endophthalmitis occurred in both healthy and immunocompromised hosts, mainly caused by cataract surgery (67.3%). In contrast, almost all endogenous endophthalmitis patients were immunocompromised. Among all patients, previous history of tuberculosis infection was identified in 4 cases (3.5%). Rapid growing NTMs were responsible for exogenous endophthalmitis, while endogenous endophthalmitis were commonly caused by slow growers. Treatment regimens consisted of macrolides, fluoroquinolones or aminoglycosides, which were continued for up to 12 months. Initial and final vision were generally worse than 6/60. CONCLUSIONS: NTM endophthalmitis is a serious intraocular infection that leads to irreversible loss of vision. The presentation can mimic a chronic recurrent or persistent intraocular inflammation. History of multiple intraocular surgeries or immune-deficiency in patient with chronic panuveitis should raise the practioner's suspicion of NTM endophthalmitis. Appropriate diagnosis and treatment are important to optimize visual outcome.

BACKGROUND: Good syndrome (GS) is an adult-onset immunodeficiency characterized by coexisting thymoma and hypogammaglobulinemia. Clinical course after treatment with intravenous immunoglobulin (IVIg) has rarely been reported. OBJECTIVE: To investigate and report the clinical course and outcomes of GS patients after treatment with IVIg at Thailand's largest national tertiary referral hospital METHODS: This retrospective chart review included patients diagnosed with GS and treated with IVIg during the 1 January 2005 to 31 December 2015 study period. RESULTS: Nine GS patients with a median age at diagnosis of 53 years were included. Pneumonia and sepsis were the most common clinical manifestations. Six infectious organisms suggestive of cell-mediated immunity defect occurred in six patients, including cytomegalovirus (CMV), Mycobacterium tuberculosis, Mycobacterium abscessus, Herpes simplex virus (HSV), Pneumocystis jirovecii, and Aspergillus. Mean serum IgG level was 317 mg/dL. Eight patients had very low to undetectable B-cells. Five patients had either low CD4 number or impaired T-cell function, and one patient had both. All patients received IVIg replacement therapy monthly at a dose of 0.4 g/kg. The mean trough IgG level was 881 mg/dL. After treatment with IVIg replacement, seven patients had favorable clinical outcomes. However, two patients expired due to septicemia. CONCLUSION: Clinical outcomes of patients with GS are more dependent on the severity of infections and associated hematologic and autoimmune diseases than on the severity of thymoma itself. Therefore, early recognition and prompt IVIg replacement may change the natural course of this condition and may be successful in keeping the patient infections free.

BACKGROUND: Although atypical mycobacteria had been increasingly found in various ocular infections in the past decades, a slow-growing Mycobacterium haemophilum (M. haemophilum) was scarcely reported. Similar to tuberculous infection, the presentation can masquerade as low-grade granulomatous intraocular inflammation with partial response to corticosteroids. Besides, the special requirements for culture make this pathogen difficult to diagnose. The study aims to report the clinical presentation and notify the awareness of NTM endophthalmitis among clinicians. This is the first case report of late-onset, postoperative M. haemophilum endophthalmitis in the literature. CASE PRESENTATION: A 66-year-old man with non-insulin-dependent diabetes mellitus (NIDDM) manifested chronic granulomatous inflammation in the left eye after multiple glaucoma surgeries. With a diagnosis of noninfectious panuveitis, he was treated with systemic corticosteroids. The inflammation initially responded to therapy although it subsequently worsened and became purulent endophthalmitis. The vitreous cultures grew M. haemophilum. Intraocular and systemic antimicrobial treatments were administered early, but the patient eventually turned blind. CONCLUSIONS: M. haemophilum endophthalmitis is a rare but serious intraocular complication leading to loss of vision or eyeball. Awareness of atypical mycobacterial infections is necessary especially in patients with impaired immune function, previous intraocular surgery, and corticosteroid resistance. Proper laboratory investigations and treatments should be performed. However, due to the rarity of the disease, the development of guidelines for its investigation and therapy is still challenging.

PURPOSE: To describe a proportion of uveitis and to analyse differences between immune-related uveitis and infectious uveitis groups. METHODS: A retrospective study of 458 uveitis patients were categorized into immune-related uveitis, infectious uveitis, masquerade, and undetermined groups. The pattern of inflammation was described. Subgroup analysis was performed to compare pattern differences between immune-related uveitis and infectious uveitis groups. RESULTS: The most common location of inflammation was the anterior eye segment. Vogt-Koyanagi-Harada disease was the most common identifiable cause. From multivariate analysis, variables found to be significantly different between immune-related uveitis group and infectious uveitis group were age of onset, presence of systemic autoimmune diseases, HIV infection, and laterality. CONCLUSIONS: Idiopathic anterior uveitis was the most prevalent diagnosis. Vogt-Koyanagi-Harada disease was the most common identifiable uveitis. Most immune-related uveitis patients were young and presented with chronic bilateral panuveitis, with most patients in the infectious uveitis group presenting with chronic unilateral posterior uveitis.

BACKGROUND: Cytomegalovirus retinitis (CMVR) is one of the most common opportunistic infection in immunocompromised individuals. Intravitreal ganciclovir injection has been used successfully but no standard regimen was established. Risks of drug toxicity, endophthalmitis, and injection-related complications increased with number and frequency of injection. The aim of this study is to evaluate the outcomes of reduced-dose intravitreal ganciclovir (2 mg/0.04 mL) for the treatment of CMVR. METHODS: A prospective observational cohort study involving 67 eyes of 49 patients with CMVR was performed. Induction therapy involved intravenous ganciclovir (10 mg/kg/day) for 2 weeks unless contraindicated or patients refused. Patients were then treated with reduced-dose intravitreal ganciclovir every week for 4 weeks, and then every other week until the lesion healed. The patients' demographic data were recorded, and vision parameters were examined every visit. RESULTS: Twenty eyes (29.9 %) presented with initial visual acuities less than 6/60. The majority of patients were diagnosed with CMVR in zones 1 or 2 (63 eyes, 94 %), and, at least, one quadrant of the retina was involved (56 eyes, 83.6 %). Forty-one eyes (61.2 %) completely resolved after treatment within the 6-month follow-up. There was no significant difference in healing time, whether or not patients received induction treatment with intravenous ganciclovir (111.00 ± 12.96 vs 105.00 ± 28.32 days, p = 0.8). Five eyes (12.2 %) of patients with healed CMVR had visual acuities less than 6/60. CONCLUSIONS: Reduced-dose intravitreal ganciclovir is a safe and effective treatment option. It provides comparable results to other weekly regimens. Induction with intravenous ganciclovir is not crucial in a resolution of retinitis, although it may be necessary to reduce systemic cytomegalovirus loads and mortality rates. TRIAL REGISTRATION: The trial was registered with Thai Clinical Trials Registry (TCTR) on 16 March 2016 - TCTR20160316001 .

The present study aimed to investigate the clinical outcomes of autologous cultivated oral mucosal epithelial transplantation (COMET) on human amniotic membrane (AM) for corneal limbal stem cell deficiency (LSCD). In this prospective, noncomparative case series, 20 eyes (18 patients) with bilateral severe ocular surface disease were chosen to undergo COMET on human AM. The primary outcome was clinical success, and the secondary outcomes were the best-corrected visual acuity difference, corneal opacification, symblepharon formation, and complications. The mean patient age was 48.2 ± 15.5 years. The mean follow-up time was 31.9 ± 12.1 months (range 8-50 months). All except one eye exhibited complete epithelialization within the first postoperative week. A successful clinical outcome, defined as a stable ocular surface without epithelial defects, a clear cornea without fibrovascular tissue invasion at the pupillary area, and no or mild ocular surface inflammation, was obtained in 15 of 20 eyes (75 %). The clinical success rate at 1 year was 79.3 %, and that at 4 years (end of follow-up) was 70.5 %. Fourteen of 20 (70 %) eyes exhibited improvement in visual acuity after COMET, and some required subsequent cataract surgery (2 eyes), penetrating keratoplasty (3 eyes), or keratoprosthesis implantation (1 eye). Preoperative symblepharon was eliminated in most eyes (8 of 13, 61.5 %) after COMET combined with eyelid reconstruction when needed. The only complication was corneal perforation (1 eye) induced by a severe eyelid abnormality; treatment with a tectonic corneal graft was successful. COMET can successfully restore ocular surface damage in most eyes with corneal LSCD.

This retrospective cohort study investigated patients with cytomegalovirus anterior uveitis (CMV AU) and compared treatment outcomes between regional and systemic antiviral therapies. Treatment modalities included topical (2% ganciclovir [GCV] eye drops or 0.2% GCV eye gel) and systemic (intravenous GCV or oral valganciclovir) groups. The comparison parameters included response rates, time to response, recurrence rates, time to recurrence, and complications. Forty-four patients (54.5% male) with a mean age of 56 ± 9.87 years were enrolled, with 31 eyes in the topical group and 13 eyes in the systemic group. The median response time was significantly slower in the topical group (63 days [IQR 28-112]) compared to the systemic group (28 days [IQR 24-59]) (p = 0.04). Treatment response rates were 87.1% (27/31) in the topical group and 100% (13/13) in the systemic group (p = 0.30), while recurrence rates were 37% (10/27) and 69.2% (9/13) (p = 0.056), with a median time to recurrence of 483 days [IQR 145-1388] and 392 days [IQR 203.5-1907.5] (p = 0.20), respectively. In conclusion, both topical and systemic GCV treatments demonstrated favorable outcomes for CMV AU. Systemic GCV showed rapid control of intraocular inflammation.

Introduction: Syphilis exhibits a wide range of clinical presentations, mimicking various systemic and ocular diseases. Ocular syphilis, in particular, manifests with multiple presentations, ranging from anterior uveitis to panuveitis, making it a potential differential diagnosis for Behçet's uveitis. Here, we present a unique case of Behçet's panuveitis that was undergoing immunomodulatory therapy and was complicated by ocular syphilis. Notably, this case also featured rare cutaneous manifestations associated with secondary syphilis, commonly known as malignant syphilis. Case Presentation: A 38-year-old Thai man with refractory end-stage Behçet's panuveitis reported a maculopapular rash accompanied by increased intraocular inflammation. The escalation of immunomodulatory therapy, intended to manage the provisional diagnosis of active ocular and cutaneous Behçet's disease, resulted in clinical deterioration, with the rash transforming into multiple noduloulcerative lesions. Despite negative serologic tests for syphilis at baseline before initiating immunomodulatory therapy, syphilis infection was eventually diagnosed following reevaluation and the observation of spirochetes in a skin biopsy specimen. The patient was treated with intravenous penicillin G, resulting in an improvement in intraocular inflammation and resolution of noduloulcerative rashes. Conclusion: Intraocular inflammation and mucocutaneous lesions in syphilis can mimic the presentation of Behçet's disease. The introduction of immunomodulatory therapy may alter the clinical picture, leading to a severe and atypical presentation. A high index of suspicion for reevaluating serologic tests or performing tissue biopsies is warranted for an accurate diagnosis.
RESUMO
This study investigated the efficacy of golimumab in the management of refractory non-infectious panuveitis. Nineteen patients (38 eyes; mean age, 31 years) were retrospectively reviewed between June 2016 and June 2022. All patients had bilateral eye involvement and Behçet's disease was the most common diagnosis (57.9%). Compared to the period before golimumab treatment, the rate of uveitis relapses after golimumab treatment significantly decreased from 1.73 to 0.62 events per person-years (incidence ratio 0.33, 95% confidence interval 0.19-0.57, P < 0.001). After golimumab therapy, 12 patients (63.2%) were able to reduce the number or dosage of immunosuppressive drugs, and the median dosage of systemic corticosteroids was reduced from 15.0 to 7.5 mg/d (P = 0.013) compared to baseline. The median logMAR visual acuity improved from 0.9 at baseline to 0.6 at the last visit (P = 0.006). Golimumab demonstrated efficacy against refractory non-infectious panuveitis in terms of a corticosteroid-sparing effect and reduced the rate of uveitis relapses to approximately one-third.

PURPOSE: To investigate the incidence of and predictive factors for recurrent cytomegalovirus retinitis (CMVR) in human immunodeficiency virus (HIV)-negative patients. METHODS: A retrospective review of HIV-negative patients who were newly diagnosed with CMVR between January 2005 and February 2019. RESULTS: Of 28 patients (44 eyes), 35.9% of eyes had a recurrence of CMVR after discontinuation of anti-CMV therapy. The incidence of CMVR recurrence was 17 per 100 eye-years. The factors significantly associated with CMVR recurrence were eyes with retinitis area of more than 25% (P = .013), absence of vitreous haze (P = .003), neutropenia at presentation (P = .001), and absence of systemic immunosuppression therapy prior to presentation (P = .002). CONCLUSION: Eyes with a large area of retinitis, absence of vitreous haze, and neutropenia at presentation are predictive of CMVR recurrence while receiving systemic immunosuppression prior to CMVR presentation has a lower risk of CMVR recurrence.
RESUMO
OBJECTIVE: To report histopathologically proven bacterial infection manifested multifocal interstitial (stromal) keratitis (IK) with definite previous history of prolong topical steroid use. Standard managements of bacterial keratitis did not provoke enough benefit. MATERIAL AND METHOD: A retrospective analysis of 19 eyes in 15 patients referred to Siriraj Hospital between 2004 and 2010. RESULTS: Multifocal intrastromal infiltration, with relatively quiet ocular reaction and mild inflammation were initially presented in all eyes. They all previously had been diagnosed of presumed viral keratitis, and had been given topical corticosteroid treatment for a prolonged period of time without healing. Autoimmune disease workups were all negative. Corneal scrapings showed negative culture results in all eyes. However, bacteria within stromal lamellae with absent or minimal inflammatory cells were demonstrated in all eyes by corneal biopsies. In addition, cytology results obtained from 16S rDNA sequencing revealed Stenotrophomonas maltophilia in one eye and coagulase-negative staphylococci in two eyes. No case responded well to intensive topical and systemic antibiotics. However they were successfully treated with penetrating keratoplasty (11 eyes, 57.9%) or intrastromal antibiotic injections (8 eyes, 42.1%). CONCLUSION: Bacterial infection should be a concern in prolonged chronic IK. This was considered as primary bacterial IK or bacterial superinfection in immunocompromised cornea. Early recognition and appropriately aggressive managements contribute to successful outcome. Corneal biopsy is always essential and 16S rDNA sequencing is useful in this distinct clinical entity.

Tuberculous uveitis (TBU) comprises a broad clinical spectrum of ocular manifestations, making its diagnosis challenging. Ophthalmologists usually require evidence from investigations to confirm or support a clinical diagnosis of TBU. Since direct isolation of the causative organism from ocular specimens has limitations owing to the small volume of the ocular specimens, resultant test positivities are low in yield. Immunodiagnostic tests, including the tuberculin skin test and interferon-gamma release assays (IGRAs), can help support a clinical diagnosis of TBU. Unlike the tuberculin skin test, IGRAs are in vitro tests that require a single visit and are not affected by prior Bacillus Calmette-Guerin vaccination. Currently, available IGRAs consist of different techniques and interpretation methods. Moreover, newer generations have been developed to improve the sensitivity and ability to detect active tuberculosis. This narrative review collates salient practice points as a reference for general ophthalmologists, such as evidence for the utilization of IGRAs in patients with suspected TBU, and summarizes basic knowledge and details of clinical applications of these tests in a clinical setting.
RESUMO
A prospective randomized control trial of 140 eyes from 140 patients, who underwent phacoemulsification, was conducted to compare the efficacy of subtenon corticosteroids injection with corticosteroids eye drops for controlling postoperative intraocular inflammation. Seventy patients received subtenon 20-mg triamcinolone injection (TA group), whereas the other 70 patients received 0.1% dexamethasone eye drops (Dexa group) after the uneventful surgeries. We examined and measured anterior chamber inflammation (ACI) score, laser flare-cell metering, conjunctival redness, pain, discomfort, visual acuity, intraocular pressure, and central foveal thickness on 1, 7, 14, 28 and 90 days postoperatively. At one month after the surgery, full recovery (zero ACI score) was found in 43 patients (63.20%) in the Dexa group versus 47 patients (68.10%) in the TA group (p = 0.55). There were no statistically significant differences in aqueous cells (p = 0.37) and flare (p = 0.86) between the two groups at one month. All participants experienced no serious adverse events. In conclusion, we found no statistically significant difference between subtenon 20-mg triamcinolone injection and 0.1% dexamethasone eye drop to control inflammation postoperatively. A single subtenon 20-mg triamcinolone injection could be an alternative anti-inflammatory treatment for an uneventful phacoemulsification.

Vernal keratoconjunctivitis (VKC) is an underdiagnosed and underrecognized ocular surface disease with limited epidemiological data in Asia. It is more prevalent in warm, dry, and windy climates, and often has a substantial impact on a patient's quality of life. In rare cases, VKC can be associated with vision loss, either through corticosteroid overuse or inadequate treatment of persistent inflammation. As a potentially severe and complex disease, there is variability with how VKC is managed across Asia and among the various allergic eye diseases. Diagnosis and treatment of patients with VKC is a challenge for many ophthalmologists, since no precise diagnostic criteria have been established, the pathogenesis of the disease is unclear, and anti-allergic treatments are often ineffective in patients with moderate or severe disease. In addition, the choice of treatment and management strategies used for patients varies greatly from country to country and physician to physician. This may be because of a lack of well-defined, standardized guidelines. In response, the Management of Vernal Keratoconjunctivitis in Asia (MOVIA) Expert Working Group (13 experts) completed a consensus program to evaluate, review, and develop best-practice recommendations for the assessment, diagnosis, and management of VKC in Asia. The expert-led recommendations are summarized in this article and based on the currently available evidence alongside the clinical expertise of ophthalmologists from across Asia with specialism and interest in the ocular surface, VKC, and pediatric ophthalmology.
RESUMO
BACKGROUND: Dry eye (DE) is a chronic inflammatory disease of the ocular surface of the eye that affects millions of people throughout the world. Smartphone use as an effective health care tool has grown exponentially. The "Dry eye or not?" app was created to evaluate the prevalence of symptomatic DE, screen for its occurrence, and provide feedback to users with symptomatic DE throughout Thailand. OBJECTIVE: The purpose of this study was to compare the prevalence of symptomatic dry eye (DE), blink rate, maximum blink interval (MBI), and best spectacle-corrected visual acuity (BSCVA) between people with and without symptomatic DE and to identify risk factors for symptomatic DE in Thailand. METHODS: This cross-sectional study sourced data from the "Dry eye or not?" smartphone app between November 2019 and July 2020. This app collected demographic data, Ocular Surface Disease Index (OSDI) score, blink rate, MBI, BSCVA, and visual display terminal (VDT) use data. The criterion for symptomatic DE was OSDI score ≥13. RESULTS: The prevalence of symptomatic DE among individuals using this smartphone app in Thailand was 85.8% (8131/9482), with the Northeastern region of Thailand having the highest prevalence, followed by the Northern region. Worse BSCVA (median 0.20, IQR 0.40; P=.02), increased blink rate (median 18, IQR 16; P<.001), reduced MBI (median 8.90, IQR 10.80; P<.001), female sex (adjusted OR 1.83; 95% CI 1.59-2.09; P<.001), more than 6 hours of VDT use (adjusted OR 1.59; 95% CI 1.15-2.19; P=.004), and lower than bachelor's degree (adjusted OR 1.30; 95% CI 1.03-1.64; P=.02) were significantly associated with symptomatic DE. An age over 50 years (adjusted OR 0.77; 95% CI 0.60-0.99) was significantly less associated with symptomatic DE (P=.04). CONCLUSIONS: This smartphone DE app showed that the prevalence of symptomatic DE in Thailand was 85.8%. Signs and risk factors could be also evaluated with this smartphone DE app. Screening for DE by this app may allow for the development of strategic plans for health care systems in Thailand.

To identify triggering factors for the next inflammatory episode of recurrent acute anterior uveitis (RAAU), a 1:1 case-control study was conducted. We interviewed RAAU patients with recent acute anterior uveitis attack and quiescent controls for their information during a previous month using Srithanya Stress Test (ST-5) and questionnaires about potential triggering factors. Asymptomatic controls were matched for age (± 5 years), sex, and HLA-B27. There were 39 pairs of cases and controls. Patients who recently experienced a uveitis attack demonstrated higher mean ST-5 scores (3.7 ± 2.9 vs 0.7 ± 1.1) and shorter sleep time (6.3 ± 1.4 vs 7.4 ± 0.7 h per day) compared with their controls. In the multivariate conditional logistic regression analysis, ST-5 score ≥ 3 (OR 9.07, 95% CI 1.14-72.16, p = 0.037) and sleep time < 7 h per day (OR 12.12, 95% CI 1.37-107.17, p = 0.025) were more likely to trigger a uveitis attack in RAAU accounted for patients' age, sex, HLA- B27 positivity, and presence of concurrent anti-inflammatory drugs for co-existing diseases. Other suspected triggering factors were not found to have any significant association. In short, stress and inadequate sleep may lead to the future episode of acute anterior uveitis in RAAU. Both physical and emotional stress management should be advised to RAAU patients to minimize recurrences and further complications.
