The Fundus Part II,The macular area is the most sensitive part of the retina for photopic or daylight vision, and is represented in the occipital lobes by the largest area on the visual cortex. Macular disease is one of the commonest causes of blindness and results in the loss of the central visual field.

Trauma to the Eye Part I,The exposed position of the eye makes it very susceptible to injury. While the bony orbital margin provides some protection from blunt injury by large objects, the lids are not an effective barrier to small sharp objects.

Debility

Trauma to the Eye Part II,Damage to the constrictor muscle fibres of the iris causes a dilation of the pupil as a result of the unopposed action of the dilating fibres. This mydriasis tends to be permanent.

Squint,There are many different terms used in the English language to describe a squint—for example, strabismus, cast, turn, wall-eyed and cross-eyed—but they may mean different things to different people. Even the term squint may be used to describe the screwing up of the eyes.

The Eye in Systemic Disease,The fundus of the eye offers a unique opportunity for the easy examination of part of the vascular tree and for the early diagnosis of conditions affecting this system.

Neuro-ophthalmology,Many conditions involving the central nervous system affect the eye. The ocular symptoms may be obvious, as with visual loss or double vision. Occasionally, however, the symptoms may be slight and only careful investigation will reveal unsuspected signs that can help to localize the possible site of the lesion.
