![]() Fossilized dental remains indicate that the giant panda committed to bamboo as its principal food source at least three million years ago. As much as 16 out of every 24 hours is spent feeding, and elimination of wastes occurs up to 50 times per day. Pandas solve this problem by rapidly passing prodigious quantities of the grass through their digestive tracts on a daily basis. Despite adaptations in the forepaws, teeth, and jaws for bamboo consumption, the giant panda has retained the digestive system of its carnivore ancestry and is therefore unable to digest cellulose, a main constituent of bamboo.

The authors wish to highlight a group of children who, due to well-meant but harmful traditional practices in combination with neglect and sometimes outright abuse, present with ophthalmic manifestations. This is still not the case in most low-income countries. Helplines are available whereby children can call for help in the event of abuse. In many middle- or high-income countries, there is now emergency guidance and advice. In developing countries, poverty, social and cultural beliefs and taboos and exposure to traditional practices predispose the vulnerable paediatric group to abuse. ![]() ![]() In high-income countries, it is recognised that factors such as broken families, social dysfunction, depression and unemployment play a major role, for instance, in child battering (physical assault of children). However, more information is needed, in particular from Africa. Improved media reporting in recent years has exposed some of the neglect and abuse children are subject to in many societies. It is estimated that childhood blindness causes 90 million blind years (number blind x length of life). The challenge lies in a better understanding of the immense eye problems affecting the under-served and vulnerable paediatric group in developing countries and in devising comprehensive national programmes to deal with these problems. ![]() Most strategies are aimed at the adult group. Yet, they are conspiculously neglected when national eye health and rehabilitation programmes are planned. In developing countries, children may account for 40–50% of the total population. It states that all countries shall ensure good health for children and protect them from neglect and all forms of exploitation. ![]() This calls for special care and protection of children because of their vulnerability. It is partly the increased, multifactorial, infant and young child morbidity and mortality that led to the United Nations Convention on the Rights of the Child. A helpless child, victim of traditional and social practices, enters into a life of almost 50 blind and hopeless years. A ‘concoction’ of various herbs is prepared and prescribed which subsequently leads to bilateral total damage of the corneae, a disruptive ‘keratomalacia-like’ reaction. An old lady takes a grandchild, out of concern and compassion, to a traditional healer for advice and prevention of cataract, a condition the child is likely to develop sixty years later. ![]()
