Imaging Retinal Activity in the Living Eye.

Area of Science:

• Neuroscience
• Ophthalmology
• Vision Science

Background:

• Traditional human studies of retinal function rely on psychophysical methods.
• Invasive physiological approaches have limited detailed functional vision studies in animal models.
• The electroretinogram is an exception, offering non-invasive retinal assessment.

Purpose of the Study:

• To review recent advances in in vivo retinal imaging for understanding retinal neuron function.
• To highlight novel methods revealing new patterns of retinal function in animal models.
• To emphasize the shift towards functional assessment of healthy and diseased retinas.

Main Methods:

• In vivo retinal imaging techniques.
• Optophysiology for novel functional insights.
• Review of existing and emerging retinal imaging technologies.

Main Results:

• Optimized existing imaging methods are enhancing retinal studies.
• New methods like optophysiology reveal novel patterns of retinal function.
• In vivo imaging provides a functional perspective beyond anatomical studies.

Conclusions:

• Advances in in vivo retinal imaging are crucial for understanding retinal neuron function.
• These techniques offer a new paradigm for studying both healthy and diseased eyes.
• The field is moving towards a functional understanding of the retina, complementing anatomical knowledge.
