Abstract
SE PRESENTA UN PERIMETRO EN QUE LA SUPERFICIE DE PROYECCION DEL GLOBO INCLUYE UNA SECCION SEMIESFERICA (H) UNIDA POR UN PERIMETRO CILINDRICO (C) PARA IMPARTIR A LA SUPERFICIE DE PROYECCION INTERIOR DEL INSTRUMENTO UN PERFIL "EN FORMA DE BALA" (S). EL PERIMETRO DE DIMENSION PREFERENTE INCLUYE UNA SEMIESFERA DE DIAMETRO REDUCIDO QUE OCUPA LOS 45 (GRADOS) CENTRALES DE UN ANGULO SOLIDO DESDE EL OJO DEL PACIENTE CON LA MIRADA FIJA (E). EL PERIMETRO CILINDRICO SE ENCUENTRA UNIDO A LA SEMIESFERA Y GENERADO ALREDEDOR DE UN EJE CILINDRICO QUE COMIENZA EN EL CENTRO ESFERICO DE LA SEMIESFERA Y QUE SE EXTIENDE HACIA AFUERA EN PERPENDICULAR DESDE LA SEMIESFERA AL PUNTO DE COLOCACION DEL OJO DEL PACIENTE. EL DIAMETRO DEL CILINDRO COINCIDE Y FORMA UN SERIE CONTINUA DE PROYECCION CON EL RADIO DE LA SEMIESFERA.
