What is MEM Retinoscopy?
In MEM retinoscopy the patient binocularly fixates a target in the plane of the retinoscope positioned at the near reading distance. The examiner observes the retinoscopic reflex and briefly introduces spherical lenses in front of one of the patient’s eyes until the first neutral reflex is observed.
Which drugs give spasm of accommodation effect in eye?
Cyclopentolate, Atropine, Tropicamide, and Homatropine are the typical cycloplegic eye drops used once daily to treat spasm of accommodation by relaxing the ciliary muscle. One side effect is blurred vision since these induce dilation.
Is accommodative spasm permanent?
Because general accommodative spasm is most often temporary, no treatment is needed. When people suffer from symptoms more often, vision therapy is prescribed. Vision therapy may be simple eye exercises or eye exercises combined with special lenses.
Is accommodative spasm the same as pseudomyopia?

The ratio accommodative-convergence (AC) over accommodation (A) indicates the relationship between the amount of convergence produced by a stimulus to accommodate and the amount of accommodation which produces that convergence.
How do you treat accommodative spasms in adults?
The accommodative spasm is usually treated with cycloplegic or myotic eye drops, plus or minus lenses, but occluders and amytal abreaction may not respond to any treatment and could be problematic[1],[3].
