Cone-Specific Filter-Based Neuromodulation: A Proposed Clinical Framework for Amblyopia, Strabismus, and ADHD

Area of Science:

• Neuroscience
• Ophthalmology
• Photobiology

Background:

• Cone-specific neuromodulation offers targeted visual pathway stimulation.
• Standardized protocols are needed for reproducible research in visual disorders.

Purpose of the Study:

• To propose a standardized clinical protocol for cone-specific neuromodulation.
• To classify therapeutic filters for selective S-, M-, and L-cone stimulation.
• To translate optical and safety parameters into condition-specific frameworks for amblyopia, strabismus, and ADHD.

Main Methods:

• Re-evaluation of spectral filters using transmittance and cone-excitation data.
• Integration with α-opic metrology, photobiological standards, and neurophysiological evidence.
• Definition of reproducible ranges for wavelength, illuminance, timing, modulation, and safety.

Main Results:

• Consolidation of eleven monochromatic and six combined filters into operational classes.
• Mapping of filters onto mechanistic profiles for amblyopia, strabismus (esotropia, exotropia, vertical deviations), and ADHD.
• Presentation of time frames and applications as methodological anchors.

Conclusions:

• A structured, safety-anchored framework is provided for designing cone-specific neuromodulation trials.
• The protocol aims to enhance comparability across future studies.
• Therapeutic benefit requires demonstration in prospective clinical investigations.
