The analysis of cornea morphology using corneal topographers is a clinical practice for the diagnosis of keratoconus in contact lens fitting. The recently technique has developed with the possibility of achieving a great number of measuring points of both anterior and posterior corneal surfaces in c...

각막이란 무엇인가? | 각막은 인간 눈의 전체 굴절의 약 2/3을 차지 하는 시력에 큰 영향을 미치는 조직이다. | |
현재 각막의 지형은 어디에 기초를 두고 개발한 것인가? | 현재 각막의 지형은 1880년에 Antonio Placido da costa3)에 의해 Goode Keratoscope에 기초를 두고 개발하였다. 그가 개발한 장치는 각막위에 동심원상의 투사를 통해서 각막 전방 표면의 정확한 측정을 하도록 하였다. | |
19세기 후반기에 Javal가 고안한 것의 목적은 무엇인가? | 19세기 후반기에 Javal은 각막형태의 양적 분석을 최초 수행한 것으로 각막계에 Placido discs를 결합하여 각막영상의 넓은 시야를 영상으로 획득하는 것을 고안하였다. 그는 나타난 영상을 사진으로 재생되도록 하였고, 모식도 위에 이것이 나타나도록 고안하였다. 즉 각막 표면에서 관찰된 곡률에서 변화에 대한 분석을 하는데 목적을 두었다. |
