Impact of Telemedicine on Blood Glucose Control and Ophthalmic Screenings for Patients with Diabetes in Remote Areas During the COVID-19 Pandemic: A Real-World Study in Northern Taiwan.

Introduction: The purpose of this study was to assess the impact of telemedicine on ophthalmic screening and blood glucose control for patients with diabetes in remote areas of Northern Taiwan during the coronavirus disease 2019 (COVID-19) pandemic. Methods: Telemedicine was implemented in Shiding and Wanli Districts using a 5G platform from April 2021 to December 2022. Patients with poorly controlled diabetes received real-time consultations from endocrinologists at Far Eastern Memorial Hospital, 50 km away, for medication adjustment, diet control, and lifestyle recommendations. The study also provided cloud-upload blood glucose meters for self-monitoring and regular medical advice from hospital nurses. Ophthalmic screenings included fundus imaging, external eye image, and intraocular pressure measurement, with instant communication and diagnosis by ophthalmologists through telemedicine. A satisfaction questionnaire survey was conducted. Results: The study enrolled 196 patients with diabetes. Blood glucose and glycosylated hemoglobin levels were significantly reduced after applying telemedicine (p = 0.01 and p = 0.005, respectively). Ophthalmic screenings led to hospital referrals for 16.0% with abnormal fundus images, 15.6% with severe cataract or anterior segment disorders, and 27.9% with ocular hypertension or glaucoma. Fundus screening rates remained high at 86.3% and 80.4% in 2022, mainly using telemedicine, comparable with the traditional screening rate in the past 5 years. The overall satisfaction rate was 98.5%. Conclusions: Telemedicine showed effectiveness and high satisfaction in managing diabetes and conducting ophthalmic screenings in remote areas during the COVID-19 pandemic. It facilitated early diagnosis and treatment of ocular conditions while maintaining good blood glucose control and fundus screening rates.

Clinical and Epidemiological Profiles of Retinal Vasculitis in Northern Taiwan.

PURPOSE: To investigate the epidemiological and clinical profiles in retinal vasculitis in an Asian cohort. METHODS: A 5-year retrospective study of 487 uveitis patients in a tertiary referral center at northern Taiwan. RESULTS: Overall, 18.5% of the cases were associated with retinal vasculitis (RV). Sarcoidosis and cytomegalovirus retinitis were two leading diagnoses. Cases with RV were younger (mean: 39.7 years), less unilateral (50%), and had more chorioretinal involvement (95.5%). Definite diagnosis was reached in 86.7% of RV cases, of which 38.5% had infectious uveitis. While sole arteritis was presented in 8.9% of cases, 63.3% showed phlebitis, and 27.8% involved both. Three distinctive patterns were associated with a higher likelihood of infection: nodular sheathing, continuous perivascular sheathing (OR 4.79), and continuous fluorescein leakage (OR 4.11). CONCLUSION: The presence of RV, especially arteritis, is highly suggestive of identifiable etiology. Distinctive clinical patterns help differentiation of infectious versus noninfectious causes.

Clinical Manifestations and Implications of Nonneoplastic Uveitis Masquerade Syndrome.

PURPOSE: To investigate the clinical manifestations and systemic and ocular implications of nonneoplastic uveitis masquerade syndrome (NNUMS). DESIGN: Retrospective case series. METHODS: The clinical data of 830 consecutive patients who presented with uveitis at a tertiary referral center in northern Taiwan between August 2013 and August 2020 were analyzed. The clinical characteristics and outcomes of patients with NNUMS were evaluated. RESULTS: Overall, 3.7% of patients were determined to have uveitis masquerade syndrome. Among them, 24 patients (77%; 34 eyes) were diagnosed as having NNUMS. The main presenting anatomical location was posterior uveitis (58.8%). In the NNUMS group, a high chorioretinal involvement rate (94.1%) and delayed diagnosis from symptom onset (45.8% cases were diagnosed after more than 90 days) were found. Multimodal imaging was the major decisive diagnostic factor. Systemic condition alterations requiring urgent treatment were noted in 29.2% of cases. Ocular complications were noted in 58.8% of cases; 60% of those were observed on referral. Following appropriate treatment, visual acuity could be maintained in 88.3% of cases. The 5 major categories of NNUMS were retinal vascular disorders, rhegmatogenous retinal detachment, retinal dystrophy, central serous chorioretinopathy, and uveal effusion syndrome. CONCLUSION: NNUMS is a group of heterogeneous diseases with a complex diagnostic process and significant ocular and systemic effects. High awareness regarding common clinical manifestations is crucial for physicians to make the appropriate diagnosis and management.

Ocular inflammatory manifestations following COVID-19 vaccinations in Taiwan: A case series.

As a continuing demand for booster shots against SARS-CoV-2, ocular adverse events following the coronavirus disease-2019 (COVID-19) vaccines can cause significant visual impairment, and they warrant a high awareness and detailed documentation of possible ocular inflammatory manifestations. We present a case series of 11 patients presenting with ocular manifestations relevant to vaccine-associated autoimmune response within 6 weeks after the vaccination of the Oxford-AstraZeneca, the Moderna, and Pfizer-BioNTech vaccines at the main tertiary referral center in the most populated and most vaccinated city in Taiwan. Their diagnosis included five acute anterior uveitis, two multiple evanescent white dot syndrome, one probable Vogt-Koyanagi-Harada disease, one anterior scleritis, one relapsed idiopathic panuveitis, and one autoantibody-related central retinal artery occlusion. This report presented a broad spectrum of the ocular inflammatory events following the vaccination of COVID-19. Early recognition of the clinical manifestations mentioned herein with prompt management is crucial in recovering the patients' vision.

Risk of obstructive sleep apnea among patients with Cushing's syndrome: a nationwide longitudinal study.

OBJECTIVE: Previous studies have demonstrated the association between Cushing's syndrome (CS), obstructive sleep apnea (OSA), and the risk factors for OSA, but rarely provided the evidence within a large population. Using the Taiwan National Health Insurance Research Database, we attempted to investigate the association between CS and OSA, and to provide persuading evidences. METHODS: In our study, 1612 patients with CS and 1612 age-, sex-, and comorbidities-matched controls were included, and followed up to the end of 2011. Cases of OSA were identified during the follow-up. RESULTS: Among patients with CS, 53 developed OSA (incidence: 4.11 per thousand person-year) compared with 22 in the control group (incidence: 1.70 per thousand person-year) during the follow-up (p < 0.001). CS patients had a 2.82-fold higher risk of developing OSA (HR = 2.82; 95% CI: 1.67-4.77) in later life. DISCUSSION: Our study was the first longitudinal study to support the temporal association between CS and risk of OSA. Patients with CS were associated with an increased likelihood of OSA. Further studies would be required to investigate the exact underlying mechanisms between CS and OSA, and elucidate whether the prompt intervention for CS may reduce the risk of subsequent OSA.
