Retinal neurons

Retinal neurons are the specialized nerve cells of the neurosensory retina responsible for converting light into electrical signals and processing early visual information before it is sent to the brain. This complex population includes photoreceptors (rods and cones), bipolar cells, horizontal cells, amacrine cells, and retinal ganglion cells, which together form a highly organized circuit for visual transduction [1][2]. Degradation or death of these neurons is the underlying cause of many blinding conditions, including glaucoma, retinitis pigmentosa, and age-related macular degeneration [3][4]. While 'Retinal neurons' as a whole is a cellular category rather than a specific molecular target, individual proteins and receptors within these cells serve as targets for pharmacological interventions, such as alpha-2 adrenergic receptors for neuroprotection or the RPE65 protein for gene therapy [5][6]. Maintaining the survival and functional integrity of these neurons is the primary objective of current ophthalmic drug development and regenerative medicine.
