摘要: | 對於青光眼的患者而言,監控眼壓變化為重要的診斷項目,所以需要有觀察裝置。眼壓監控是普遍用於調控抗青光眼藥劑劑量和頻率的必要條件。
在論文中,我們提出一個完全被動的,非侵入性的光學裝置,且可監控眼壓。此裝置是利用隱形眼鏡上做圖案結構,再利用兩層疊合形成莫列條紋進而量測,並利用豬眼為樣本,量測豬眼角膜的曲率半徑隨者注入水壓的變化情形。我們並利用TracePro光學追跡軟體建立光學模型,以模擬光場情形。也製做了兩種眼壓光學傳感器置,於豬眼上做檢測。與一些其他眼壓計比較,我們的裝置較單純,被動式,沒有嵌入電路,並預期能用於監測青光眼患者的眼壓變化。 Monitoring intraocular pressure (IOP) has been known as an important diagnostic procedure to treat glaucoma patients; therefore, to have a convenient monitoring tool is essential. Additionally, continual IOP monitoring is required for administrating the dosage and the frequency of anti-glaucomatous medicine for the patients. In this work, a fully passive, non-invasive optical device is proposed for continual IOP monitoring. The device is fabricated with structured pattern on the contact lens, and does the measuring by the moiré pattern obtain from double layer covered together. Porcine eye was used as the sample, and measured the variation of radius of curvature while the water injected in the porcine eye. We have set up optical models in ray-tracing software, which is called TracePro, to simulate the optical characteristics. We also fabricated two types of optical intraocular sensor and settled them on porcine eye for sensing. Compared to other contact lens-based sensors, our device is simple, passive, no imbedded electric circuit, and capable for monitoring the IOP variability of glaucoma patients. |
