• Neuroanatomy and functional vision: mapping structural–functional relations from the optic thalamus to retina, plus pupillary dynamics and reflexive eye movements to infer perception–action coupling in health and disease. [5], [6], [12], [16], [19].

• Ocular pathology and tissue disease: cross-tissue pathology and inflammation—cornea, iris, retina, and choroid—through histopathology, etiology, and case evidence on sympathetic ophthalmia, retinal glioma, and edema (commotio retinae). [1], [2], [5], [10], [13], [18].

• Genetics and development in vision: hereditary ocular diseases, pigment inheritance in mice, amblyopia-related retinal fusion differences, and embryonic eye development as a window into genetic control of ocular structures. [4], [14], [15], [17].

• Experimental ophthalmology and regeneration: embryo-eyed models, corneal epithelium regeneration under normal and therapeutic conditions, and psychiatric-era ocular reactions highlighting experimental methods. [4], [9], [20].
