(b) Accommodation. In the case of myopes accommodation should be

assessed with correcting glasses in position. The acceptable values for
accommodation in various age groups are given in Table 1.

Ocular muscle balance is dynamic and varies with concentration, anxiety,
fatigue, hypoxia, drugs and alcohol. The above tests should be considered

together for the final assessment. For example, cases just beyond the
maximum limits of the Maddox Rod test, but who show a good binocular

response, a good objective convergence with little difference from subjective
convergence, and full and rapid recovery on the cover tests may be

accepted. On the other hand, cases well within Maddox Rod test limits, but
who show little or no fusion capacity, incomplete or no recovery on the cover

tests, and poor subjective convergence should be rejected. Standards for
assessment of Ocular Muscle Balance are detailed in Appendix C to this

chapter.

Any clinical findings in the media (Cornea, Lens, Vitreous) or fundus, which
is of pathological nature and likely to progress will be a cause for rejection.

This examination will be done by slit lamp and ophthalmoscopy under
mydriasis.
