traduction Definition and Scope of neuro-ophthalmology Neuro-ophthalmology is the subspecialty of ophthalmology and neurology that studies and treats disorders of the part(s of the eye, orbit and nervous system Neuro-ophthalmologists manage patients with complex and severe neuro- ophthalmological disorders The scope of the clinical practice of neuro-ophthalmology varies widely in part because it blends the skills and services of its two parent disciplines; neurology and ophthalmology
Intraduction • Definition and Scope of Neuro-ophthalmology Neuro-ophthalmology is the subspecialty of ophthalmology and neurology that studies and treats disorders of the part(s) of the eye, orbit and nervous system. Neuro-ophthalmologists manage patients with complex and severe neuroophthalmological disorders. The scope of the clinical practice of neuro-ophthalmology varies widely, in part because it blends the skills and services of its two parent disciplines; neurology and ophthalmology
