Other terminology include anisometropia, when the two eyes have unequal refractive power, [15] and aniseikonia which is when the magnification power between the eyes differ. [16] Refractive errors are typically measured using three numbers: sphere, cylinder, and axis. [17] Sphere: This number denotes the strength of the lens needed to correct ...
When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%.

[ 2][ 3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye ...
Rod cells are photoreceptor cells in the retina of the eye that can function in lower light better than the other type of visual photoreceptor, cone cells. Rods are usually found concentrated at the outer edges of the retina and are used in peripheral vision. On average, there are approximately 92 million rod cells (vs ~6 million cones) in the ...
