The correct answer is  Diurnal variation of IOP: Usually, there is a tendency of higher IOP in the morning and lower in the evening. This has been related to diurnal variation in the levels of plasma coisol. Normal eyes have a smaller fluctuation (< 5 mm of Hg) than glaucomatous eyes (> 8 mm of Hg).
