Blunt injury to the eye can lead to hyphaema, detachment (due to haemarrhage), dislocation of lens, damage to macula, damage to drainage angle of the eye, orbital fracture or cataract as a late effect. Out of all the options given vitreous detachment is the best suited. Ref: BC of eyes: Volume 1 - Page 31.

Among the options given, temporal lobe tumor compress the inferior retinal fibers resulting in the visual field defect called superior quadrantopia (pie in the sky). If a pituitary adenoma compress the optic chiasma from below, initially it result in upper bitemporal quadrantopsia followed by bitemporal hemianopsia. Craniopharyngioma compress optic chiasma from above, and initially result in lower bitemporal quadrantopsia followed by bitemporal hemianopsia
