B
Nuclear cataract
C
Spasm of accomodation
D
Presbyopia
High-Yield 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
