It cannot be used, however, to identify causes of poor vision related to retinal or optic nerve damage, such as retinal dystrophy or optic atrophy... For this, appropriate referral is needed... Use a direct ophthalmoscope with the lens power set at ‘0’... Make sure the batteries are charged... Sit about half a metre (50 cm) away... Hold the ophthalmoscope close to your eyes... Encourage the child to look at the light source and direct the light at the child's eyes individually and together... You should see an equal and bright red reflex from each pupil... To determine whether the red reflex is normal, comparison with the red reflex of a parent of the child maybe helpful... If you are not sure whether the reflex is normal, dilate the pupil for a complete examination.

Figure 4. The red reflex is less bright in the left eye and the corneal reflection is not centred. This is a squint, which maybe the result of a serious underlying condition. Even if there is no underlying condition, squint may lead to amblyopia (loss of function in the visual cortex), which is irreversible if not treated urgently. Refer the child to a specialist

Figure 6: Figure 4. The red reflex is less bright in the left eye and the corneal reflection is not centred. This is a squint, which maybe the result of a serious underlying condition. Even if there is no underlying condition, squint may lead to amblyopia (loss of function in the visual cortex), which is irreversible if not treated urgently. Refer the child to a specialist

Mentions: Pay attention to the colour and brightness of the red reflex. It should be identical in both eyes (Figure 1). Any difference between the eyes, an absence of the red reflex or an abnormal colour (Figures 2–4) may indicate a serious illness.
