pinguecula

A small, flat, yellowish spot, sometimes raised and fatty-looking, on the CONJUNCTIVA over the exposed areas of the white of the eye. Pingueculas are almost universal in people living in tropical areas and, if large and protuberant, may lead to the development of PTERYGIUM.

pinguecula 

A benign degenerative tumour of the bulbar conjunctiva that appears as a slightly raised, yellowish-white, oval shaped thickening on either side of the cornea, but usually the nasal side. Histologically, it consists of a deposition of hyaline substance. It becomes more common in elderly people, especially those exposed to high levels of ultraviolet radiation, wind and dust. Although benign, surgical excision may be requested for cosmetic reasons (Fig. P10). See pterygium.

La hiperplasia conjuntival, la pinguecula y el pterigio son neoformaciones de la conjuntiva bulbar interpalpebral.
El objetivo del presente trabajo fue explorar la asociacion entre la exposicion ocupacional a polvo de cemento Portland y la ocurrencia de hiperplasia conjuntival, pinguecula y pterigio entre los trabajadores de una empresa cementera de Bogota, despues que una primera aproximacion realizada mediante un programa de vigilancia permitio determinar una elevada ocurrencia entre este grupo de trabajadores.
Las variables incluidas fueron: edad, sexo, cargo y los diagnosticos de hiperplasia conjuntival, pinguecula y pterigio.
Al comparar la prevalencia de las alteraciones conjuntivales entre las secciones de la empresa se encontraron diferencias estadisticamente significativas para el pterigio (p=0,004) y la pinguecula (p=0,018); para la hiperplasia conjuntival no se encontraron diferencias (p=0,907).
