휴대용 안압 측정을 비전 센서 기반 정렬 시스템 개발

초록

Elevated intraocular pressure(IOP) is a primary cause of glaucoma, rendering IOP measurement essential for diagnosis. Traditional IOP measurement devices are bulky and stationary, necessitating movement between consultation and measurement rooms. Portable tonometers address this issue but face challenges in ensuring proper alignment between the cornea and the device for precise measurements. This study proposes a method enabling medical professionals or third parties to determine this alignment using a portable tonometer. The proposed alignment system is designed considering structural compactness and cost competitiveness and comprises three light sources and vision sensors. To validate the proposed system, experiments were conducted, proving its ability to determine the alignment between the cornea and the system.
