目标：方法：对70例原发性开角型青光眼或原发性闭角型青光眼患者，自行外用抗青光眼药物治疗至少6个月后，进行滴眼技术评价。所有患者均使用与在家滴注抗青光眼药物相同的技术在1只眼睛中滴注泪液替代品。记录的参数包括滴注第一滴所需的时间、滴注眼药水的次数、滴眼药水的接触位置、与瓶尖的任何接触以及滴注后眼睑或泪管的闭合情况。滴注第一滴所需的平均时间为14.8 +/- 3.7秒（范围：8.7 - 23.5秒）。每次滴注从瓶中挤出的平均滴数为1.8 +/- 1.2滴（范围：1 - 8滴）。22例（31.43%）滴于眼睑或面颊部。53名患者（75.7%）将瓶子尖端接触到地球仪或眼周组织。滴注后20例（28.57%）闭眼，4例（5.7%）泪点阻塞。仅6例（8.57%）患者能正确滴入（挤出1滴入结膜囊内，不接触瓶口）。这可能是青光眼药物治疗中无意不依从的重要原因。
Aim: To evaluate the technique of eye drop instillation in glaucoma patients.Methods: Seventy patients with primary open-angle glaucoma or primary angle-closure glaucoma, self-administering topical antiglaucoma medications for at least 6 months were evaluated. All patients instilled a tear substitute in 1 eye using the same technique they used for instilling antiglaucoma medications at home. The parameters that were recorded included time taken to instill the first drop, number of eye drops instilled, drop contact location, any contact with the tip of the bottle, and closure of the eyelids or tear duct after drop instillation.Results: The mean age of the patients was 54.1 +/- 10.0 years. The mean time taken to instill the first drop was 14.8 +/- 3.7 seconds (range, 8.7 to 23.5 s). The mean number of drops squeezed from the bottle per instillation was 1.8 +/- 1.2 drops (range, 1 to 8 drops). In 22 patients (31.43%), the eye drops fell on the eyelids or cheek. Fifty-three patients (75.7%) touched the tip of the bottle to the globe or periocular tissue. Twenty patients (28.57%) closed eyes after instilling drops and 4 patients (5.7%) occluded the punctum. Only 6 patients (8.57%) were able to correctly instill the eye drops (squeeze out 1 drop and instill it into the conjunctival sac without bottle tip contact).Conclusions: Nearly, 9 of 10 glaucoma patients were unable to instill eye drops correctly. This may be an important cause of unintentional noncompliance in glaucoma medical therapy.
