Corneal blindnesses make up a main public health problem in numerous developing countries where they constitute a sign of low sanitary level. The main diseases which cause corneal blindnesses are: Trachoma. Xerophthalmia. Measles. Corneal ulcerations and keratitis. Onchocercosis. Neonatorum ophthalmia. Leprosy. Injuries. Some therapeutic practices. Epidemiological analysis leads to the definition of risk groups: Small children. Isolated rural communities. Unhealthy urban communities. Out of place populations. Under-fed populations. Only a joint prevention can be able to fight against this social, economic, a human plague constituted by corneal blindnesses. Simple prevention measures which are often not very expensive, showed their efficiency. They are as follows: Individual and collective hygiene measures. Improvement of alimentary conditions. Earliness and quickness in ocular care. Vaccination against measles. Improvement of the care to mother and child. Sanitary education for prevention. These prevention tasks are supported by the health workers who are spread out inside the population. Their formation, the means they are granted with constitute a main priority which has to be taken into account in the choices and the decisions to be made in order to fight against blindness linked with cornea opacification with efficacy.

The chief causes of corneal blindness was found to be corneal inflammatory diseases and injury in 83.4% of the 3,499 cases (3,993 eyes) of corneal blindness that presented themselves during 1983-1985 at the authors' hospital. The important diseases in order of frequency were herpes simplex keratitis (42.8%), bacterial keratitis (17.4%), corneal injuries (15.7%), keratomalacia (10.0%), and trachoma (3.8%). Patients of the latter two diseases were mostly old cases. The authors discussed the incidence of corneal diseases and their prevention and treatment.

An epidemiological survey of blindness and low vision in Chongqing showed that in a random sample of 13,832, there were 62 cases of bilateral blindness and 97 cases of bilateral low vision, the prevalences being 0.45% (male 0.38%, female 0.52%) and 0.70% (male 0.50%, female 0.90%) respectively. The prevalences in people over 60 years of age were significantly higher. The important blinding diseases were cataract, infectious keratitis, corneal turbidity, glaucoma, trachoma, and ametropia/amblyopia.

A detailed study was made of the prevalence and associations of trachoma in a prospective, randomised population based study of 9058 Palestinian Arabs living in the West Bank and Gaza Strip, and in a prospective study of 1,000 consecutive unselected ophthalmic outpatients at St John Ophthalmic Hospital, Jerusalem. Trachoma was found to be widely distributed throughout the two regions. This chiefly occurred as a mild, self limited disease, interspersed with discontinuous pockets of blinding disease. The highest prevalence was found in the Hebron and Jericho districts. Sub-populations at increased relative risk included females, older age groups, rural dwellers, patients with pre-disabling or disabling lesions, and patients with moderate to severe active trachoma. An increased recovery of bacteria by culture of the lids and conjunctiva of patients with moderate to severe trachoma was noted. Prevalences of lacrimal disease, dacryocystitis, and acute bacterial ulcer were significantly greater among outpatients with trachoma than among those without trachoma. No difference in prevalence of either mucopurulent conjunctivitis or herpetic dendritic keratitis was demonstrated between patients with and without trachoma. An increased prevalence of trachoma was found in communities without a continuous year-round supply of running water compared with communities with this facility.

The causes of blindness in Sierra Leone were studied in 7286 new patients attending the eye clinic in the year 1981. Blindness, defined as an inability to count fingers at 3 meters with the better eye (WHO, 1973), was present in 762 persons, due to cataract (39%), ocular onchocerciasis (30%), primary glaucoma (8%), measles keratitis (3%), trachoma (3%) and other causes. The prevalence of blindness was estimated from simple field surveys covering 41 villages with an estimated population of 10,559. The average prevalence of blindness was found to be 1.3% of the total population.

In an Egyptian leprosy hospital, 17% of 133 patients had a visual acuity of less than 3/60. Corneal opacity, phthisis bulbi, and cataract accounted for 85% of blindness. Leprosy and trachoma together produce blinding corneal opacity by exposure, leprous keratitis, and trichiasis and entropion. Inturned lids, a late result of conjunctival scarring due to childhood trachoma, were less frequent in patients with lepromatous leprosy than in patients with tuberculoid leprosy; because conjunctival scarring from trachoma depends on cell-mediated immunity, patients with lepromatous leprosy may not have had severe trachomatous scarring develop due to their lifelong abnormality in cellular immunity. In patients with leprosy, even when complicated by trachoma, simple measures to prevent or restore vision include medical treatment of leprosy, surgical correction of lid deformities, sector iridectomy for constricted pupils or central corneal opacities, and cataract extraction.

Eye diseases in 1028 children below 15 years of age, seen at the Eye clinic of the University College Hospital, Ibadan, Nigeria were studied. Refractive error, vernal conjunctivitis, measles keratitis associated with malnutrition and those referrable to injuries were leading causes of eye problems amongst children. Diseases of ocular adnexa (excluding orbital cellulitis) squints, glaucoma, uveitis and trachoma were rare.

We observed 6 cases of secondary keratoconus with Fleischer's ring pattern corneal epithelial iron ring. These 6 cases were 2 males and 4 females. The causes of secondary keratoconus were 2 cases of trachoma, 2 cases of trauma, 1 case of keratitis, and 1 case of unknown origin. All showed thinning of the cornea and Fleischer's ring pattern corneal epithelial iron ring. After penetrating keratoplasty of 1 case, the button of the recipient showed the deposition of hemosiderin in the corneal epithelium stained blue by Prussian blue. At the same time we confirmed the existence of iron in the corneal epithelium by the X-ray ultimate analysis. Fleischer's ring is considered to be characteristic of keratoconus, but we have found that Fleischer's ring is also seen in secondary keratoconus in which the cornea becomes thinner secondarily for some reason.

Ophthalmologist with a 4-year history (1993-1997) of practice at the Russian Red Cross Hospital in Addis Ababa (Ethiopia) shares his experience. More than 30,000 patients were examined and treated. Interesting cases are described: cytomegalovirus retinitis in the presence of AIDS, AIDS-associated involvement of the eyes (uveitis, keratitis, Kaposi's sarcoma), herpes zoster involvement of the eyes, phlyctenar keratoconjunctivitis, vernal conjunctivitis, trachoma, diseases of the eyes concomitant with syphilis, a case with Vogt-Koyanagi-Harada. Clinical course and therapy of these diseases under local conditions are described.

The specific morphology and distribution of corneal surface lesions may point toward a specific diagnosis and pathogenesis in individual cases (see Fig 1). Staining lesions may be fine (e.g., staphylococcal) or punctate (e.g., keratitis sicca). The size and appearance of staining and nonstaining lesions of the epithelium and subepithelial cornea may be characteristic for a particular disease process (e.g., HSV, EKC). Finally, the location of lesions is important. Inferior staining (staphylococcal disease, lagophthalmos) will be incited by a different cause as compared to superior (molluscum, trachoma, vernal keratoconjunctivitis) and peripheral (contact lens-induced, collagen vascular disease) staining patterns. Central lesions are more likely to indicate tear deficiency, superficial corneal dystrophies, viral infections, or metabolic conditions. Knowledge of these patterns of disease can allow accurate diagnosis and more expedient and successful treatment of corneal surface disease.
