A 6 years old child has a cycloplegic refraction OD +6.00 D, OS +2.00 D. What is the best way to manage the anisometropia?

. Partial correction

. Pleoptic therapy

. Give +4.00 D both eyes and occlude left eye

. Full optical correction

. Prescribe atropine eye drop and full optical correction

Transposition: Identify the incorrect answer:

. – 3.00 / - 1.25 x 180 = - 4.25 / + 1.25 x 180

. +2.00/ -4.00 x 180 = -2.00/ +4.00 x 90

. + 1.00 / + 3.00 x 90 = + 4.00 / - 3.00 x 180

. + 5.00 / - 1.00 x 75 = + 4.00 / + 1.00 x 165

. - 6.00 / + 2.50 x 125 = - 3.50 / -2.50 x 35

Using Spherical Equivalent: Identify the incorrect answer

+ 5.00 / -1.00 x 75 = + 4.50

. -1.50/ +3.25 x 45 = +0.25

. – 3.00 / - 1.25 x 20 = + 1.75

. + 2.00 / - 4.00 x 180 = plano

. – 6.00 / + 2.50 x 125 = - 4.75
