Intraocular-pressure continuous glaucoma detection system and detection method thereof

Abstract

The invention belongs to the technical field of detection and treatment of ophthalmic diseases and particularly discloses an intraocular-pressure continuous glaucoma detection and drug delivery systemwhich comprises a corneal contact lens. An intraocular-pressure detection circuit and a drug delivery circuit are integrated in the corneal contact lens, the intraocular-pressure detection circuit isused for detecting intraocular-pressure information and transmitting the intraocular-pressure information to a single chip microcomputer outside the corneal contact lens in a wireless manner, and thesingle chip microcomputer judges the intraocular pressure according to the received information. When the intraocular pressure is beyond a normal range, the single chip microcomputer wirelessly supplies power to the drug delivery circuit, and a drug is delivered after rectification by the drug delivery circuit. The detection system can continuously detect the fluctuation of the intraocular pressure and the abnormal increase of the intraocular pressure for a long time, can timely adopt an iontophoresis mode to carry out controllable drug delivery when the intraocular pressure exceeds the normal range, and ensures the real-time detection of the intraocular pressure and timely, efficient and controllable drug treatment. In addition, the system has the advantages of portability, small irritation to eyes, no limitation by places and time for diagnosis and treatment of glaucoma, high drug utilization rate and the like.

Description

technical field [0001] The invention belongs to the technical field of detection systems for ophthalmic diseases, and in particular relates to a glaucoma intraocular pressure continuous detection and treatment system and a detection method thereof. Background technique [0002] Glaucoma refers to a common and difficult eye disease in which the intraocular pressure is intermittently or continuously elevated. This persistent high intraocular pressure can cause damage to various parts of the eyeball tissue, atrophy of the optic nerve, resulting in constriction of the visual field, vision loss and even blindness. What is even more worrying is that glaucoma is currently the world's number one irreversible blinding eye disease, and its impact is more serious than cataract. In addition, the intraocular pressure of glaucoma patients can rise sharply in a short period of time, causing patients to feel headache and eye pain. If the intraocular pressure is not controlled to a normal le...

Problems solved by technology

[0009] First, the medicine dripped in the eyes is easily diluted or cleared by tears;

[0010] Second, relevant studies have shown that 50% to 100% of drugs will enter the digestive tract and blood circulation system through the nasolacrimal duct, so the actual utilization rate of eye drops drugs is extremely low, and the retention time in the eyes is short;

[0011] Third, adding eye drops requires certain skills, which is not suitable for the elderly and the disabled. In addition, some drugs for the treatment of glaucoma (such as timolol) can cause arrhythmia and Serious consequences such as bronchospasm
