Pupil dilation typically begins within 15 minutes and may last for 3–8 hours. [6] [7] After the pupil has been dilated, an ophthalmoscope can be used to examine the fundus. This allows for 15x magnification of the optic disc, also known as the optic nerve head, and retina to better evaluate for any ophthalmic pathology. [9]
The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.
Tropicamide, sold under the brand name Mydriacyl among others, is a medication used to dilate the pupil and help with examination of the eye. [3] Specifically it is used to help examine the back of the eye. [4] It is applied as eye drops. [3] Effects occur within 40 minutes and last for up to a day. [3]
Greater pupil diameter was observed after the items were heard (depending on how many items were heard), and decreased after items were repeated. [57] The more difficult the task, the greater pupil diameter observed from the time preceding the solution [ 58 ] until the task was completed. [ 59 ]
The Marcus Gunn pupil is a relative afferent pupillary defect indicating a decreased pupillary response to light in the affected eye. [3] In the swinging flashlight test, a light is alternately shone into the left and right eyes. A normal response would be equal constriction of both pupils, regardless of which eye the light is directed at.

The results of both tests and teacher assessments were reported using a common scale of attainment levels, numbered 1 to 8 across the three key stages, with the national expectation that pupils would achieve Level 2 at the age of 7; Level 4 at the age of 11; and Level 5 or 6 by the age of 14.
In 2005, 51,077 pupils sat for the examination, a 0.4% increase from the previous year. The majority (or roughly 97.8%) of the pupils qualified for secondary school. 62.2% of those who passed were eligible for the Special (Integrated Programme or The International Baccalaureate) or the Express stream (Either one for 4 years only) and the remaining 35.6% were eligible for either the Normal ...
