We developed a coinsized occlusion dose monitor (ODM) to measure compliance with patch-wearing during the treatment of amblyopia objectively. It measures the temperature difference between the front and back of the ODM every 2-5 minutes by means of two thermistors. The data is stored in EEPROM memory and read out after recording for a week by connecting it to a PC. The ODM measures 35x23x4 mm and weighs 6 g. The back of the ODM is glued to the front of the amblyopia patch with double-sided Scotch tape. When the patch with the ODM is on the eye, the temperature at the back of the ODM is higher than at the front. Compliance is being studied in children taking part in a large amblyopia cohort study. The parents were instructed during home visits every three months to put the ODM on the patch. After a week, the ODM was collected and read out. Although the parents knew that a recording was being made, compliance was mediocre in many cases. Children were patched infrequently, for 5 minutes only, for long periods on the last days of the recording, at night, etc. Diaries detailing patch time were unreliable.
我们开发了一种硬币大小的遮盖剂量监测仪（ODM），用于客观测量弱视治疗期间眼罩佩戴的依从性。它通过两个热敏电阻每2 - 5分钟测量一次ODM前后的温差。数据存储在电可擦可编程只读存储器（EEPROM）中，记录一周后通过连接到个人电脑（PC）读出。ODM尺寸为35×23×4毫米，重6克。ODM的背面用双面 Scotch 胶带粘在弱视眼罩的正面。当带有ODM的眼罩戴在眼睛上时，ODM背面的温度高于正面。正在对参与一项大型弱视队列研究的儿童的依从性进行研究。每隔三个月家访时，指导家长将ODM放在眼罩上。一周后，收集并读出ODM的数据。尽管家长知道正在进行记录，但在很多情况下依从性一般。儿童很少佩戴眼罩，仅佩戴5分钟，且在记录的最后几天、晚上等长时间佩戴。详细记录佩戴时间的日记并不可靠。
