Lecture On Olfactory & Optic Nerve Assessment: Testing, Visual Pathways & Field Defects | MBBS

This comprehensive practical session from Santiniketan Medical College & Hospital, Agartala, is essential for MBBS students preparing for clinical postings and practical vivas. We provide a step-by-step demonstration of examining the Olfactory (CN I) and Optic (CN II) nerves, integrating clinical skills with the relevant anatomy and pathophysiology. In this lecture, we decode the visual pathway, demonstrate how to perform visual acuity and field tests, and explain the interpretation of various visual field defects—vital for high-stakes medical exams. 📌 Lecture Chapters (Key Moments for Google Search): [00:00] - Clinical Testing of Olfactory Nerve (CN I) [01:25] - Understanding Anosmia, Hyposmia, and Hyperosmia [07:29] - Visual Pathway Anatomy & Physiology [16:20] - Visual Acuity: Snellen’s Chart, Jaeger’s Chart & Ishihara Test [23:03] - Significance of 6/6 and 6/60 Vision [31:31] - Visual Field Examination (Confrontation Test) [36:54] - Clinical Significance: Field Defects (Monocular Blindness, Bitemporal Hemianopia) [43:32] - Homonymous Hemianopia & Quadrantanopia Explained [58:22] - Pupillary Reflexes: Direct & Indirect Light Reflex [01:03:46] - Accommodation Reflex Demonstration #CranialNerveExam #MBBS #Ophthalmology #ClinicalSkills #MedicalEducation #Anatomy #SantiniketanMedicalCollege #Agartala #OSCE #VisualPathway #MedicalViva #NEETPG SANTINIKETAN MEDICAL COLLEGE & HOSPITAL Real Classroom Demonstration/Lecture On: PHYSIOLOGY by Dr. Riddhit Mondal MBBS Batch: (2025-26) Conducted on: 05-06-26
