Tất cả các công cụ ngoại trừ ASOCT dựa vào ánh sáng trong quang phổ nhìn thấy được. Về mặt lý thuyết, như với gonioscopy, ánh sáng nhìn thấy có thể ảnh hưởng đến tình trạng góc trong thời gian thi. | 74 M. Baskaran All the instruments except the ASOCT rely on light in the visible spectrum. Theoretically as with gonioscopy visible light may affect the angle status during examination. References 1.

APPENDIX D COST EFFECTIVENESS CEA OF SCREENING FOR PRImArY ANGLE CLOSURE GLAUCOMA Augusto Azuara Blanco Augusto Azuara Blanco and Jennifer Yip Overview Health economics is concerned with the allocation of scarce resources in order to maximize health benefits. This area has become increasingly important as there is greater demand with new technologies demographic changes and increased public awareness. Economic evaluation allows us to compare alternatives based on both costs and consequences and thus assists decision makers in making difficult choices. There are four main types of economic evaluations which differ mainly in their assessment of consequences. Cost minimization analysis - comparing .
