AIM: To describe a case in which vitrectomy was required for vitreous hemorrhage and fibrovascular proliferation after laser-induced chorioretinal venous anastomosis (LCVA) for non-ischemic central retinal vein occlusion (CRVO).METHODS: Observational case report.RESULTS: A 72-year-old man complained of central scotoma in the left eye, and was diagnosed as suffering from non-ischemic CRVO. LCVA was performed in another hospital. Although favorable visual function was briefly maintained postoperatively,severe vitreous hemorrhage developed in his left eye, necessitating vitrectomy. CONCLUSION: Considering that LCVA carries a risk of serious complications, we must apply this treatment with caution, especially in ethnic groups, such as the Japanese, in whom pigmentation reacts to photocoagulation excessively.

Globally, there are currently three major competency models for healthcare professions education: CanMEDS 2015 in Canada, Accreditation Council for Graduate Medical Education Six-Competency model in the United States, and Tomorrow's Doctors in the United Kingdom. An investigation by the Revision Committee for the Japanese National Model Core Curriculum revealed that these competency models had been utilized in seven countries. In each country investigated for revision, medical schools were allowed to implement these major competency models flexibly. Although each university has a high degree of freedom in curriculum design and educational delivery, each country is regulated by a quality assurance system that requires accreditation by the World Federation for Medical Education (WFME) and other organizations. The 2022 Revision of the Japanese National Model Core Curriculum has also been translated into English and released to the global audience in the field.
