The review presents an analysis of clinical trials results for autologous cultured oral mucosal epithelium transplantation (COMET) in patients with bilateral corneal limbal stem cell deficiency (LSCD) over the past 15 years. Detailed characteristics and evaluation are given for anatomical outcomes, visual acuity changes, and complication rates. The results obtained during the analysis confirm the consistency of the concept of corneal re-epithelization by means of COMET. COMET promoted persistent corneal re-epithelization in 81.5% of cases, and visual acuity improvement in 78.8% of patients with LSCD. COMET does not require systemic immunosuppression, and it is accompanied by much smaller numbers and significantly lower grades of complications compared with keratoprosthesis. About 15% of patients experienced developing superficial peripheral corneal neovascularization regressed spontaneously by 12 months of observation. Based on the COMET clinical trials results, the management of patients with bilateral LSCD is under optimization by reference to the pathogenesis of the underlying disease. Thus, autologous cultured oral mucosal epithelium transplantation seems promising for further studies and introduction into routine clinical practice. Key words: limbal stem cell deficiency, ocular surface reconstruction, corneal epithelium, oral mucosal epithelium, transplantation.

Abstract Background This study assesses the areas and extent of impact of the Coronavirus Disease of 2019 (COVID-19) pandemic on rare disease (RD) organisations in the Asia Pacific region. There is no existing literature that focuses on such impact on RD organisations in any jurisdictions, nor RD populations across multiple jurisdictions in the Asia Pacific region. A cross-sectional survey was distributed to RD organisations between April and May 2020. Quantitative and qualitative data on the impact of COVID-19 on RD organisations and patients were collected from the organisation representative’s perspective. Qualitative data was analysed using thematic analysis. A follow-up focus group meeting was conducted in August 2020 to validate the survey findings and to discuss specific needs, support and recommendations for sustainable healthcare systems during the pandemic. Results A total of 80 RD organisations from Australia, Hong Kong Special Administrative Region of China, India, Japan, mainland China, Malaysia, New Zealand, the Philippines, Singapore and Taiwan participated in the study. Of all, 89% were concerned about the impact of pandemic on their organisations. Results indicate that 63% of the organisations functioned at a reduced capacity and 42% stated a decrease in funding as their biggest challenge. Overall, 95% believed their patients were impacted, particularly in healthcare access, social lives, physical health, psychological health and financial impact. Specifically, 43% identified the reduced healthcare access as their top impact, followed by 26% about the impact on daily living and social life. Focus group meeting discussed differential impact across jurisdictions and point towards telemedicine and digitalisation as potential solutions. Conclusions This serves as the first study to assess the impact of COVID-19 on RD patients and organisations across multiple jurisdictions in the Asia Pacific region, identifying major themes on the impact on both RD patients and organisations. By including 80 organisations from ten jurisdictions, our study presents the most comprehensive assessment of the pandemic’s impact to date. It highlights the need for mental health support and sheds light on moving towards telemedicine and digitalisation of organisation operation, which constitutes a sustainable model in times of pandemics and beyond.
