- 16. Medial Rectus
- 17. Lateral Rectus : abduction
- 19. In primary position muscle plane of the SR forms angle 23°with optical axis. In this position SR Elevates the globe. Secondary Actions intorsion and adduction
- 21. In 23° abduction, SR complete Elevator, muscle plane coincides with optical axis
- 23. Eye in primary position Muscle plane SO forms angle 54° with optical axis. Action is intorsion Secondary actions abduction and depression RE
- 24. When globe adducted 54°, Optical axis and muscle plane coincide, SO is pure depressor RE
- 25. RE In abduction SO is primarily an intortor
- 28. For right eye read from the top For left eye read from the bottom
- 44. Cover Test with and without AHP

- The condition in which the patient sees not much and the practitioner nothing at all… ! It is always (or almost always) associated with strab, aniso or form deprivation in early life. Diagnosed when there reduced letter acuity, absence of pathology and when any ametropia is corrected. The results of pyschophysical studies & electrophysiological investigations suggest little primary retinal or LGN abnormality. Instead, the most profound effects of the amblyopic process are found in the striate cortex.
