Ciliary Muscle Electrical Stimulation for Intraocular Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for glaucoma, such as eye drops and surgeries, often cause side effects or provide only temporary relief, and there is a need for a method to permanently reduce intraocular pressure without unacceptable side effects.
Innovation Solution
Electrical stimulation of the ciliary muscle using electrodes and a microcontroller to regulate intraocular pressure through a closed-loop system, adjusting pulse parameters based on measured pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If eye drops are used to treat glaucoma, then intraocular pressure is reduced, but side effects occur including eye irritation and severe heart problems
Solution Approach 1:
The patent replaces chemical treatment (eye drops) with electrical stimulation of the ciliary muscle. Electrical pulses are delivered through electrodes to stimulate the ciliary muscle, which in turn increases aqueous humor outflow and reduces intraocular pressure without the harmful side effects of chemical medications.
Solution Approach 2:
The patent changes the mechanism of action from chemical to electrical parameters. By controlling electrical pulse parameters (amplitude, frequency, duration), the system achieves precise control over ciliary muscle stimulation and intraocular pressure reduction, avoiding the unpredictable side effects of chemical drugs.
2Stress or pressure
If surgeries are used to treat glaucoma, then intraocular pressure is reduced successfully, but surgical risks occur and relief is only temporary
Solution Approach 1:
The patent employs a dynamic, adjustable electrical stimulation system that can be modified based on patient response and disease progression. Unlike static surgical interventions, the electrical parameters can be adjusted to maintain long-term pressure control and adapt to changing clinical conditions.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor intraocular pressure and adjust electrical stimulation parameters accordingly. This closed-loop control ensures sustained effectiveness and allows for long-term management of glaucoma without the need for repeated surgeries.
3Stress or pressure
If electrical stimulation is applied to the ciliary muscle, then intraocular pressure is reduced, but the system complexity increases
Solution Approach 1:
The patent divides the electrical stimulation system into separate functional components: electrodes for application, a pulse generator for signal delivery, and control mechanisms for parameter adjustment. This modular segmentation allows for easier implementation and reduces overall system complexity while maintaining therapeutic effectiveness.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces intraocular pressure chronically and safely, avoiding side effects and the need for repeated surgeries by targeting the underlying mechanisms of fluid flow in the eye.
Implementation Method 1
Electrical stimulation of the ciliary muscle using electrodes and a microcontroller to regulate intraocular pressure
Implementation Method 2
The stimulation signal causes the ciliary muscle to contract, which increases the outflow of aqueous fluid from the eye
Data Source
AI summary
An arrangement for reducing intraocular pressure includes a pulse signal source, a probe coupling, and at least one electrode. The probe coupling is configured to be supported on a portion of a living eye. The electrodes are supported on the probe coupling.
