Outline of Research at the Start

糖尿病黄斑浮腫(DME)は、中心視力の低下を来たすが原因が様々であり、治療に苦慮する疾患である。臨床ではさまざまな治療が行われているが、DMEの治療法選択は担当医師の経験や勘に委ねられており、標準治療が存在しない。
本研究ではわが国の約30の網膜硝子体専門施設の協力を得て、約2500名の未治療のDME患者を対象に、2年間の治療経過データをWEB登録システムによって収集・解析することで、「どのようなDME患者が、どのような治療をされて、どのくらい視機能が改善されたのか」を明らかにし、治療パターンと予後を解析してDMEに対する標準治療を確立するとともに、わが国のDME治療成績を明らかにしていく。

Outline of Final Research Achievements

Two-year visual outcomes for treatment-naive diabetic macular oedema in real-world clinical practice since 2015, when anti-VEGF drugs were approved for insurance coverage, were extracted from the medical records of 37 vitreoretinal specialist centres in Japan and compared by year of treatment initiation.
The 2-year visual outcome improved year by year, increasing by 7 letters, and the proportion of eyes with good visual acuity (>0.5) increased to 73.3%. Anti-VEGF therapy was found to be administered in approximately 90% of eyes, and the proportion of eyes in which it was first-line treatment increased dramatically to approximately 80%. These findings demonstrate the superiority of anti-VEGF therapy and its increasing prevalence.

Academic Significance and Societal Importance of the Research Achievements

糖尿病黄斑浮腫は失明原因ではないが、50才から70才という社会貢献の大きい年代に発症し、社会的な視力である0.5を維持できないことが問題となってきた。本研究の研究成果により、積極的に抗VEGF薬治療を行うことで、視力低下を防止できることが判明し、我が国の網膜硝子体施設では、年々この考え方にそった治療が行われていることが証明された。本研究結果が和学の糖尿病黄斑浮腫治療のガイドラインに与える影響は大きいと思われる。
