Which of the following is called as pseudomyopia 
Select and explain. 
A. Insufficiency of accomodation, B. Nuclear cataract, C. Spasm of accomodation, D. Presbyopia
C: Spasm of accomodation
Answer: C: Spasm of accomodation 
Explanation: Pseudomyopia refers to an intermittent and temporary shift in refractive error of the eye towards myopia, in which the focusing of light in front of the retina is due to a transient spasm of the ciliary muscle causing an increase in the refractive power of the eye ( Spasm of accomodation) Spasm of accomodation: A spasm of accommodation (also known as a accommodative spasm) is a condition in which the ciliary muscle of the eye remains in a constant state of contraction. Normal accommodation allows the eye to "accommodate" for near-vision. Cause Drug Induced Spasm with miotics like echothiophate Spontaneous spasm of children who attempt to compensate refractory errors Diagnosis: It is made with refraction under atropine Treatment -Relaxation of ciliary muscles by atropine
