RESUMO

We presented the development of a consensus guideline for managing juvenile idiopathic arthritis-associated uveitis (JIAU) in Taiwan, considering regional differences in manifestation and epidemiology. The Taiwan Ocular Inflammation Society (TOIS) committee formulated this guideline using a modified Delphi approach with two panel meetings. Recommendations were based on a comprehensive evidence-based literature review and expert clinical experiences, and were graded according to the Oxford Centre for Evidence-Based Medicine's "Levels of Evidence" guideline (March 2009). The TOIS consensus guideline consists of 10 recommendations in four categories: screening and diagnosis, treatment, complications, and monitoring, covering a total of 27 items. These recommendations received over 75% agreement from the panelists. Early diagnosis and a coordinated referral system between ophthalmologists and pediatric rheumatologists are crucial to prevent irreversible visual impairment in children with JIAU. However, achieving a balance between disease activity and medication use remains a key challenge in JIAU management, necessitating further clinical studies.

RESUMO

Clinical practices on acute post-operative and endogenous endophthalmitis (EnE) are highly variable among clinicians due to a lack of up-to-date, high-quality evidential support. An expert consensus is thus much needed. A panel consisting of ten retinal specialists in Taiwan was organized. They evaluated relevant literature and developed key questions regarding acute post-operative and EnE that are cardinal for practice but yet to have conclusive evidence. The panel then attempted to reach consensus on all the key questions accordingly. There were eight key questions proposed and their respective consensus statements were summarized as follows: Gram staining and culture are still the standard procedures for the diagnosis of endophthalmitis. Vitrectomy is recommended to be performed earlier than the timing proposed by the Endophthalmitis Vitrectomy Study (EVS). Routine intracameral antibiotic injection for post-cataract surgery endophthalmitis prophylaxis is not recommended because of potential compounding error hazards and a lack of support from high-quality studies. Routine fundus examination is recommended for all patients with pyogenic liver abscess. In EnE, vitrectomy is recommended if diffused and dense vitritis is present, or if the disease progresses. These consensus statements may work as handy guidance or reference for clinical practices of acute post-operative and EnE.

RESUMO

PURPOSE: In this study, we describe our experience of sympathetic ophthalmia (SO) at a tertiary referral center in Taiwan. MATERIALS AND METHODS: We retrospectively analyzed records of patients diagnosed with SO from January 2011 to December 2020. RESULTS: We collected data of 15 patients diagnosed with SO (eight males, seven females). Six patients developed SO after ocular penetrating trauma, and nine developed SO after ocular surgery, including seven with vitrectomy, one with penetrating keratoplasty, and one with cataract surgery. Penetrating ocular trauma was the primary cause of SO in the first 5 years (four of six cases), but the proportion was much lower in the last 5 years (two of nine cases). The interval between trigger events and SO ranged from 0.2 to 120 months. Nine patients received oral steroids alone, five patients received methylprednisolone pulse therapy followed by oral steroids, and immunosuppressants were added in four cases. Visual acuity of sympathetic eyes and exciting eyes improved after treatment. The initial visual acuity of sympathetic eyes in trauma related and ocular surgery related revealed no significant difference, but the final visual acuity of sympathetic eyes was better in ocular surgery-related cases than in the trauma-related cases (mean ± standard deviation, 1.01 ± 1.33 versus 0.49 ± 0.68 logarithm of the minimum angle of resolution, P = 0.021). CONCLUSIONS: With the increased number of eye surgeries performed in recent years, eye surgery has emerged as the dominant etiology of SO in our 10-year study. Early detection and proper treatment help to maintain vision in most of the SO patients.

RESUMO

Chronic hyperglycemia involves persistent high-glucose exposure and correlates with retinal degeneration. It causes various diseases, including diabetic retinopathy (DR), a major cause of adult vision loss. Most in vitro studies have investigated the damaging short-term effects of high glucose exposure on retinal pigment epithelial (RPE) cells. DR is also a severe complication of diabetes. In this study, we established a model with prolonged high-glucose exposure (15 and 75 mM exogenous glucose for two months) to mimic RPE tissue pathophysiology in patients with hyperglycemia. Prolonged high-glucose exposure attenuated glucose uptake and clonogenicity in ARPE-19 cells. It also significantly increased reactive oxygen species levels and decreased antioxidant protein (superoxide dismutase 2) levels in RPE cells, possibly causing oxidative stress and DNA damage and impairing proliferation. Western blotting showed that autophagic stress, endoplasmic reticulum stress, and genotoxic stress were induced by prolonged high-glucose exposure in RPE cells. Despite a moderate apoptotic cell population detected using the Annexin V-staining assay, the increases in the senescence-associated proteins p53 and p21 and SA-ß-gal-positive cells suggest that prolonged high-glucose exposure dominantly sensitized RPE cells to premature senescence. Comprehensive next-generation sequencing suggested that upregulation of oxidative stress and DNA damage-associated pathways contributed to stress-induced premature senescence of ARPE-19 cells. Our findings elucidate the pathophysiology of hyperglycemia-associated retinal diseases and should benefit the future development of preventive drugs. Prolonged high-glucose exposure downregulates glucose uptake and oxidative stress by increasing reactive oxygen species (ROS) production through regulation of superoxide dismutase 2 (SOD2) expression. Autophagic stress, ER stress, and DNA damage stress (genotoxic stress) are also induced by prolonged high-glucose exposure in RPE cells. Consequently, multiple stresses induce the upregulation of the senescence-associated proteins p53 and p21. Although both apoptosis and premature senescence contribute to high glucose exposure-induced anti-proliferation of RPE cells, the present work shows that premature senescence rather than apoptosis is the dominant cause of RPE degeneration, eventually leading to the pathogenesis of DR.

RESUMO

Background: Remote areas of Taiwan lack routine and specialized ophthalmology services. This study aimed to analyze feasibility of teleophthalmology service for diseases diagnosis and referral in remote areas of Taiwan. Methods: A retrospective study of medical records from 11 remote teleophthalmology clinics in the Taitung area of Taiwan was conducted from May 2020 to December 2021. Vision and intraocular pressure were checked. Ophthalmic imaging was performed by local trained nurses using a hand-held ophthalmoscope and slit lamp biomicroscope. The images were transmitted by telemedicine system to a medical center. Consultation was conducted via face-to-face real-time video calls. Ophthalmologists in the medical center provided diagnosis and treatment advice based on the real-time images and interactive history taking via the telemedicine system. All the images and data were collected and well-reviewed by ophthalmologists in the medical center, and disease prevalence and referral were analyzed for the program. A small-scale satisfaction questionnaire survey was conducted for efficacy evaluation of the program. Results: A total of 1,401 medical records from 1,094 patients were collected and screened. Patients' ages ranged from 9 months to 94 years, with a mean age of 57.27 (standard deviation ±20.47) years. The most frequent ophthalmologic diagnosis was dry eye disease (20.2%), followed by conjunctivitis (12.4%). Among 322 patients with underlying diseases of diabetes mellitus, 59 patients (18.3%) were diagnosed with diabetic retinopathy. Major diagnosis was made in 102 patients (7.3%) and referral to hospital for further management was suggested. This program had high overall satisfaction score of 89% (mean 4.43 ± 0.52 points) in satisfaction questionnaire survey. Conclusion: Teleophthalmology provides an alternative tool for ocular disease diagnosis and screening for patients in remote areas, especially during the COVID-19 pandemic. This service helps to detect major but undiagnosed diseases and promotes health care accessibility and availability in remote areas that lack specialists.

RESUMO

In recent years, optical coherence tomography (OCT) biomarkers for specific retinal diseases have been found to be associated with treatment outcome and disease recurrence. The main purposes of this study were to identify OCT biomarkers for myopic choroidal neovascularization (mCNV) treated with intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF). OCT features in 43 eyes of 39 patients with mCNV treated with anti-VEGF with at least 1 year of follow-up were retrospectively analyzed. Eyes with subretinal hyperreflective material (SHM) in baseline spectral-domain OCT (SD-OCT) had significantly more visual improvement than eyes without SHM at month 6 (p = 0.007) and had a trend of more visual improvement than eyes without SHM (p = 0.058) at month 12. Eyes with subretinal fluid (SRF) at baseline had significantly more central retinal thickness (CRT) decrease than patients without SRF at month 6 and 12 (p = 0.012 and 0.006 respectively). In univariate regression analysis, dome-shaped macula (DSM), SRF in baseline OCT image and fuzzy border of mCNV when entering pro re nata (PRN) injection protocol tended to have higher risk of disease recurrence in 1 year (odds ratio: 14.86 (p = 0.003), 3.75 (p = 0.049) and 22.92 (p < 0.001) respectively). However, they were not significant in multivariate regression analysis. OCT biomarkers at baseline could provide prognostic information for mCNV management.

RESUMO

PURPOSE: This study aims to conduct a narrative review about the current role of vitreoretinal surgery in the management of infectious and non-infectious uveitis. METHODS: This review was performed based on a search of the PubMed database or on relevant published papers according to our current knowledge. RESULTS: A total of 91 articles were identified in the literature review. With the advance of microincision vitrectomy surgery (MIVS), pars plana vitrectomy (PPV) has gained increasing popularity in the management of infectious and non-infectious uveitis. For diagnostic purposes, larger amounts of sample can be obtained by MIVS than traditional vitreous aspiration using needles. For treatment purposes, PPV removes vitreous opacities, decreases inflammatory cytokines and mediators of inflammation, and tackles related complications, including hypotony, epiretinal membrane, macular holes, and retinal detachment. Achieving optimum control of inflammation prior to surgery is important for surgical interventions for non-emergent therapeutic indications and complications of uveitis. Peri-operative inflammation management is essential for decreasing the risk of surgical intervention. An overall complication rate of 42-54% was reported with cataract to be the leading cause of complications. CONCLUSION: Most reports affirm the role of PPV in the management of infectious and non-infectious uveitis, although the quality of data remains limited by a lack of applying standardized reporting outcomes, limitations in study design, and a paucity of prospective data.

RESUMO

BACKGROUND: Patients with psoriatic arthritis (PsA) may develop uveitis, a potentially serious ocular complication. PsA-related uveitis may result in significant morbidity and even vision loss if underdiagnosed or under-treated. We presented a case with long-standing recurrent uveitis and retinal vasculitis successfully managed by fortified systemic immunomodulators for systemic PsA. CASE PRESENTATION: A 47-year-old woman was referred under the impression of acute anterior uveitis in her right eye in recent one month. Ocular examinations showed panuveitis in both eyes with intense vitreous opacity in her right eye. Fundus fluorescence angiography revealed retinal vasculitis in both eyes. Systemic surveys excluded the possibility of infection but showed an elevated inflammation marker. With intensive immunosuppressive treatment, inflammation resolved and the vision improved. CONCLUSION: Our case highlights not only the importance of intensified systemic therapy in treating PsA-related uveitis but the importance of multidisciplinary collaboration. Recurrent uveitis may be an indicator of disease activity prior to other inflammatory markers.

RESUMO

BACKGROUND: Optimal regimen using intravitreal aflibercept injections for diabetic macular edema (DME) in clinical practice remains to be elucidated. The purpose of this study is to evaluate a treat-and-extend (TAE) approach using intravitreal aflibercept in participants with center-involved DME. METHODS: A 52-week open-label, prospective, multicenter, interventional study was conducted between August 2015 and November 2017 in Taiwan. Adults with diabetes mellitus and center-involved DME who have best-corrected visual acuity (BCVA) of 73 to 24 Early Treatment Diabetic Retinopathy Study letters and central retinal thickness (CRT) >300 µm were included. Participants received five monthly loading doses of 2 mg intravitreal aflibercept, followed by a TAE regimen with a four-week increment/decrement interval over 48 weeks; the maximum interval was 12 weeks. Main outcomes included changes in BCVA and CRT from baseline to week 52, additional anatomical outcomes, and treatment burden parameters. RESULTS: Forty-five participants with mean (SD) age of 63.7 (8.3) years were analyzed. At baseline, mean (SD) BCVA and CRT were 58.3 (11.9) letters and 434.4 (116.8) µm, respectively. Changes from baseline in BCVA and CRT were +8.3 (9.3) letters and -138.2 (150.0) µm (both p < 0.001) at week 52, respectively. In addition, 22% (10/45) of patients gained ≥15 letters, 14% (6/44) of participants achieved ≥2-level improvement in diabetic retinopathy severity, and 51% (23/45) demonstrated dry retina at week 52 compared with 13% (6/45) at baseline. In total, 87% (39/45) of patients reached disease stability, entering TAE at week 20. Subsequently, 89% (40/45) of patients reached maximum interval at week 52. Mean (SD) number of injections was 7.7 (1.5) over a period of 52 weeks. CONCLUSION: This straightforward and practical TAE regimen using intravitreal aflibercept injections resulted in favorable clinical outcomes with minimal treatment burden for DME at week 52.

RESUMO

The management of neovascular age-related macular degeneration (nAMD) has taken a major stride forward with the advent of anti-VEGF agents. The treat-and-extend (T&E) approach is a refined management strategy, tailoring to the individual patient's disease course and treatment outcome. To provide guidance to implementing anti-VEGF T&E regimens for nAMD in resource-limited health care systems, an advisory board was held to discuss and generate expert consensus, based on local and international guidelines, current evidence, as well as local experience and reimbursement policies. In the experts' opinion, treatment of nAMD should aim to maximize and maintain visual acuity benefits while minimizing treatment burden. Based on current evidence, treatment could be initiated with 3 consecutive monthly injections. After the initial period, treatment interval may be extended by 2 or 4 weeks each time for the qualified patients (i.e. no BCVA loss ≥5 ETDRS letters and dry retina), and a maximum interval of 16 weeks is permitted. For patients meeting the shortening criteria (i.e. any increased fluid with BCVA loss ≥5 ETDRS letters, or presence of new macular hemorrhage or new neovascularization), the treatment interval should be reduced by 2 or 4 weeks each time, with a minimal interval of 4 weeks. Discontinuation of anti-VEGF may be considered for those who have received 2-3 consecutive injections spaced 16 weeks apart and present with stable disease. For these individuals, regular monitoring (e.g. 3-4 months) is recommended and monthly injections should be reinstated upon signs of disease recurrence.

RESUMO

We aim to investigate the role of medication adherence history in treatment needed diabetic retinopathy (TNDR). We conducted a retrospective nested case-control study using 3 population-based databases in Taiwan. The major one was the 2-million-sample longitudinal health and welfare population-based database from 1997 to 2017, a nationally representative random sample of National Health Insurance Administration enrolled beneficiaries in 2010 (LHID2010). The national death registry and national cancer registry were also checked to verify the information. The outcome was defined as the TNDR. The Medication possession ratio (MPR) was defined as the ratio of total days of diabetes mellitus (DM) medication supply divided by total observation days. MPR ≥ 80% was proposed as good medication adherence. The association of MPR and the TNDR was analyzed. Other potential confounders and MPR ratio were also evaluated. A total of (n = 44,628) patients were enrolled. Younger aged, male sex and patients with less chronic illness complexity or less diabetes complication severity tend to have poorer medication adherence. Those with severe comorbidity or participating pay-for-performance program (P4P) revealed better adherence. No matter what the characteristics are, patients with good MPR showed a significantly lower likelihood of leading to TNDR after adjustment with other factors. The protection effect was consistent for up to 5 years. Good medication adherence significantly prevents treatment needed diabetic retinopathy. Hence, it is important to promote DM medication adherence to prevent risks of diabetic retinopathy progression, especially those who opt to have low medication adherence.

RESUMO

Under metabolic stress conditions such as hypoxia and glucose deprivation, an increase in the AMP:ATP ratio activates the AMP-activated protein kinase (AMPK) pathway, resulting in the modulation of cellular metabolism. Metformin, which is widely prescribed for type 2 diabetes mellitus (T2DM) patients, regulates blood sugar by inhibiting hepatic gluconeogenesis and promoting insulin sensitivity to facilitate glucose uptake by cells. At the molecular level, the most well-known mechanism of metformin-mediated cytoprotection is AMPK pathway activation, which modulates metabolism and protects cells from degradation or pathogenic changes, such as those related to aging and diabetic retinopathy (DR). Recently, it has been revealed that metformin acts via AMPK- and non-AMPK-mediated pathways to exert effects beyond those related to diabetes treatment that might prevent aging and ameliorate DR. This review focuses on new insights into the anticancer effects of metformin and its potential modulation of several novel types of nonapoptotic cell death, including ferroptosis, pyroptosis, and necroptosis. In addition, the antimetastatic and immunosuppressive effects of metformin and its hypothesized mechanism are also discussed, highlighting promising cancer prevention strategies for the future.

RESUMO

Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation. Patients diagnosed with nAMD should be subjected to treatment with the goal of maintaining visual function while diminishing anatomical disease activity and minimizing treatment burden. Currently, anti-VEGF therapy is the main treatment strategy for nAMD, and evaluation involving comprehensive ophthalmologic examination within 1 month of completion of the loading phase comprising three monthly injections is recommended to guide subsequent management. Either a treat-and-extend or pro re nata regimen can be considered for the maintenance phase of anti-VEGF therapy, and the regimen should be chosen and adjusted according to disease activity, reimbursement criteria, financial burden, and patient preferences. In the event of inactive nAMD or poor treatment outcomes, after thorough evaluation and patient education, anti-VEGF therapy may be stopped. The consensus provides practical nAMD management guidelines for ophthalmologists and fellow healthcare professionals.

RESUMO

PURPOSE: Cytomegalovirus (CMV) retinitis is one of the most common opportunistic infections in immunocompromised patients, including patients with acquired immunodeficiency syndrome (AIDS). CMV retinitis in non-human immunodeficiency virus (HIV)-infected patients has been reported with variable presentations. Significant intraocular inflammation is common, and visual prognosis is poor if not properly managed. OBSERVATIONS: We present a case of presumed CMV retinitis in a non-immunocompromised breast cancer patient that occurred during cancer treatment. The ocular symptoms developed one day after partial mastectomy with intra-operative radiotherapy following five months of chemotherapy treatment. Ocular manifestations included panuveitis with mild peripheral retinitis. CONCLUSIONS AND IMPORTANCE: Early diagnosis and prompt treatment with oral valganciclovir based on the clinical manifestation and serologic test findings helped to preserve vision.

RESUMO

PURPOSE: Circumscribed choroidal hemangioma is a rare condition where there is development of benign vascular tumors, and it generally appears in middle-aged adults. Here we report a case of Chinese medicine, Gui Lu Er Xian Jiao - related serous retinal detachment secondary to circumscribed choroidal hemangioma. OBSERVATIONS: A 55-year-old female, who had no remarkable ocular or medical history but has been taking a special Chinese compound medicine, Gui Lu Er Xian Jiao, for the past 2 years, presented with progressive blurred vision in the left eye for weeks. After serial ocular examinations, serous retinal detachment 2nd to circumscribed choroidal hemangioma was disclosed. Owing to the close timing association with medication history of Gui Lu Er Xian Jiao, we advised her to discontinue the Chinese medicine first. The serous retinal detachment resolved completely without any other management. CONCLUSIONS AND IMPORTANCE: The content of Gui Lu Er Xian Jiao has been reported to have angiogenesis effect, which possibly change the vascular permeability and induce the serous retinal detachment and therefore blurred vision in our patient. To the best of our knowledge, this is the first report on such relationship between Gui Lu Er Xian Jiao and serous retinal detachment 2nd to circumscribed choroidal hemangioma. The case report highlighted the importance of detailed history taking in the management of ocular diseases.

RESUMO

PURPOSE: To investigate the association of autophagy-related gene expression with age-related macular degeneration (AMD). METHODS: Patients with AMD were recruited for analysis by conjunctival impression cytology. mRNA was assessed by real-time polymerase chain reaction (RT-PCR) to evaluate whether the expression of 26 autophagy-related genes (ATGs) was correlated with AMD. Further studies on cell viability and autophagic flux in response to oxidative stress by H2O2 were performed in human retinal pigment epithelial (RPE) cell lines based on the results of impression cytology. RESULTS: Both the neovascular AMD (nAMD) and polypoidal choroidal vasculopathy (PCV) groups had significantly higher mRNA levels of gamma-aminobutyric acid receptor-associated protein-like 1 (GABARAPL1) and microtubule-associated proteins 1A/1B light chain 3B (MAP1LC3B) than the control group, but there was no significant difference between these two groups. Age difference existed only in the AMD group. GABARAPL1 and MAP1LC3B mRNA expression increased significantly after acute oxidative stress in adult retinal pigment epithelial (ARPE-19) cells. Cell viability significantly increased and decreased in the cells harboring GABARAPL1 expression vector and silenced with siRNA against GABARAPL1, respectively, during short-term oxidative stress, whereas viability increased in the GABARAPL1-silenced cells after long-term oxidative stress. Silencing GABARAPL1 itself caused a reduction in autophagic flux under both short and long-term oxidative stress. CONCLUSION: Our study showed the possibility of assessing autophagy-related gene expression by conjunctival impression cytology. GABARAPL1 was significantly higher in AMD. Although an in vitro study showed an initial protective effect of autophagy, a cell viability study revealed the possibility of a harmful effect after long-term oxidative injury. The underlying mechanism or critical factors require further investigation.

RESUMO

ABSTRACT: Uveitic macular edema is a significant cause of visual impairment in most uveitis types. Treatment options of uveitis have advanced remarkably in recent years. Up to now, corticosteroids remain the mainstay of treatment. Nonsteroidal immunomodulators, and recently the biologic agents, which can reinforce efficacy and enable discontinuation or reduction of steroids to maintenance doses, are becoming increasingly popular in the management of uveitic macular edema. Several medications can be used in intraocular delivery and more and more sustained releasing implants are being developed. This review will briefly focus on the review of local therapy for the management of cystoid macular edema in uveitis, as many of these novel approaches are currently being evaluated in clinical trials.

RESUMO

PURPOSE OF REVIEW: Ocular sarcoidosis is one of the most common causes of uveitis worldwide. The diagnosis and treatment of patients with ocular sarcoidosis remains challenging in some cases. It is important for clinicians to keep up to date with new diagnostic and treatment tools for this disease. RECENT FINDINGS: The International Workshop on Ocular Sarcoidosis diagnostic criteria were first proposed in 2009 and revised in 2017. The new criteria contained two parts: ocular presentation and systemic investigation. The diagnostic value of liver enzymes was reduced in the new criteria, whereas the value placed of lymphopenia and the CD4/CD8 ratio in bronchoalveolar lavage fluid were increased. Despite not being included in the criteria, recent studies have also highlighted the diagnostic value of serum soluble interleukin-2 receptors. Recent ophthalmologic imaging also provides useful insights for the differential diagnosis.Many new treatments for ocular sarcoidosis have been developed in recent years. The introduction of biological immunomodulatory agents for uveitis treatment represents a big improvement. Antitumor necrosis factor-alpha antibodies, including adalimumab, have been proven to be effective for treating ocular sarcoidosis. Many studies have also suggested that other biological agents could be effective and well tolerated. Newer intravitreal dexamethasone and fluocinolone implants have been developed. Patients treated with these implants have experienced good and sustained control of their intraocular inflammation. SUMMARY: Diagnosis and treatment options for ocular sarcoidosis have changed over time. However, challenges still exist in some difficult patients. Future studies should focus on finding more sensitive biomarkers and developing more effective immunomodulatory treatments with longer efficacy and less side effects.
