The term cataract has evolved over centuries. Constantinus Africanus (1018–1085), a famous Carthaginian monk of the school of Salerno, translated into Latin an Arabic expression depicting cataract as a flowing down of water (nuzul-el-ma) as gutta pacta or cataracta.1,2 The Arabic terminology was derived from the Alexandrian word hypochyma or its Latin translation suffusio to describe the cataract.1,2

Along the river Nile, construction of dams has led to the formation of waterfalls, and these are called cataracts (Figure 1). 3 The photographs of a gorge in Watkins Glen State Park, New York, USA, illustrate the flowing down of water (cataract) and a view through the “cataract” (Figure 2).
