Outline of Final Research Achievements

We investigated the difference in laser irradiation conditions between the conventional probe (Rev1) and the new probe (Rev2 Straight type) for the probe to be performed for micropulse trans-scleral diode laser cyclophotocoagulation (MPCPC). It was found that the Rev2 Straight type has better operability than Rev1 but is inferior in the permeability of the laser through sclera. When the Rev2 ball type was created as an improved version of the Rev2 Straight type, it was found that the Rev2 ball type is superior to the Rev2 Straight type in the permeability of the laser through sclera.

Academic Significance and Societal Importance of the Research Achievements

MPCPCで使用する従来型プローブの欠点である操作性に着眼し、操作性を重視した新型プローブ(Rev2 Straight型)について、プローブ特性や最適な照射条件について検証した。
その結果、レーザー先端形状を改善することでレーザー透過性に優れたことが判明したことで、改良型の新型プローブ(Rev2 ball型)が開発された。今後さらなる操作性・強膜透過性を目指したプローブ開発を進めることで、操作性良好かつ患者眼への負担が少ない新しいプローブ開発・臨床応用が期待できる。
