Abstract

Purpose: The main purpose of this study is to develop a device for the indicative measurement of intraocular pressure (IOP) of eyeball, a key cause for glaucoma. In early diagnosis and treatment of glaucoma accurate measurement of IOP is important. The methods and devices which are available for the measurement of IOP have their own limitations which cause discomfort to the patients during measurement and needs anesthesia. There is a dare need of a device for the measurement of intraocular pressure by making the contact of plunger with closed eyelid eliminating the need of anesthesia and expert ophthalmologist. Method: Additive manufacturing (AM) is an era of technical development and innovation. Developing a device for detecting glaucoma by using AM and TRIZ ‘The theory of inventive problem solving’ (A Collaborative approach) can overcome the disadvantages that classic tonometer have. The field of Ophthalmology will be experiencing a paradigm shift towards the use of collaborative approach of TRIZ with AM. The developed new device was tested on 40 patient’s eye at Government Hospital Bhandara, (M. S.), India. The results of new device were cross verified by expert clinicians using calibrated Schiotz’s tonometer and digital palpation technique. Result: The developed new device was tested on patient’s eye through eyelid and results were compared with calibrated Schiotz’s tonometer. The results from the new device were found in good agreement with results from Schiotz’s tonometer with the average error of 0.033 ± 0.18 (mean ± SD) mm of Hg and mean relative error was -0.0018 ±0.0096 (mean ± SD). Conclusion: There is a substantial need for early detection and diagnosis of glaucoma in rural and remote areas (worldwide). A new device for detection of glaucoma using AM and TRIZ was introduced in this paper and measurements by the new device were by currently well accepted Schiotz’s tonometer. The new device will help the medical practitioners in rural and remote areas for early detection of glaucoma.
