1. DIAGNOSTIC EVALUATION FOR STRABISMUS Ms. JayaRajini Vasanth Mphil, B.S (opt) Assistant Professor – Optometry Ophthalmology Department Sri Ramachandra University

5. In high myopia the, the fovea lies nasal to the optical axis. So, the corneal reflex lies temporal to the center of the cornea simulating esotropia. Negative angle kappa (myopia) leads to pseudo-esotropia. Large positive angle kappa (hypermetropia) leads to pseudo-exotropia.

11. Tests for sensory anomalies Worth four-dot test a - Prior to use of glasses b - Normal c - Left suppression/ amblyopia Bagolini striated glasses a - Normal or ARC b- Diplopia c - Suppression d - Right suppression/ amblyopia e - Diplopia d - Small suppression scotoma

17. Monocular eye movements A- elevation B- depression C- adbuction d- adduction E–extortion F- intortion

18. Ocular movement examination

21. Right esotropia ( RET ) Right exotropia ( RXT ) Right hypertropia ( RHT )right hypotropia Left esotropia ( LET ) Left exotropia ( LXT ) Left hypertropia ( LHT )left hypotropia Alternating esotropia ( ALT ET ) Alternating exotropia ( ALT XT )

22. E esophoria X exophoria RH right hyperphoria LH left hyperphoria E(T) intermittent esotropia X(T) intermittent exotropia RH(T) intermittent right hypertropia LH(T) intermittent left hypertropia

24. Motility tests Tests versions and ductions Grades under/overaction Left inferior oblique overaction Left lateral rectus underaction

25. Hirschberg‘s test Amount of deviation: note location of corneal light reflex 1 mm = 7 ° or 15 Δ Reflex at border of pupil = 15 ° Reflex at limbus = 45 °

28. Krimsky Test
