Pterygia are frequently observed in tropi cal and subtropical countries. In Europe pterygia are seen more frequently on the eastern shores of the Mediterranean than in the northern countries. They are rare in England (Duke-Elder1). The tables com piled by Sous2 and cited by Poncet3 give the incidence of pterygia in Europe for every 100 patients: Copenhagen, 0.23; Glasgow, 0.22; Dublin, 0.27; Paris, 0.37; Lyons, 0.39; Naples, 0.38; Barcelona, 1.05; Cadiz, 1.87. Poncet3 gives the following non-European data: Cuba, 2.54; Madeira, 10 percent of the population (Lawrence4); Borneo, Pontianak, most of the inhabitants between 30 and 40 years (Abrahams5).I have observed that the inhabitants of the island of Aruba, an island lying about 20 miles off the north coast of Venezuela, are frequently affected with pterygia. To esti mate the incidence of pterygium on the island of Aruba, a survey was made of 1,040 patients whose working and living kept them out of doors. These data are combined with those of Diponegoro and Mulock Houwer0 and Ringland Anderson7 in Table 1. Because the average daily sunshine in tropical and subtropical countries is higher than in northern countries, several authors have suggested a correlation between solar radiation and the etiology of pterygium.
