summary "Improvements introduced in field equipment". It is a device (10) for the field of ophthalmology and designed for performing monocular horizontal field exams providing comfort to the user at the time of the examination, in addition to performing it in a short time； the campimetry apparatus (10) provides a base (20) on which the metal tubular profile (30) is orthogonally installed and whose opposite end (31) is fixed to the underside (41a) of the support plate (41) installed on the inner portion of a primary junction box (50) which in turn receives on the upper wall (50a) the double chin rest (60), while the side walls (50b) of the same box (50) provide holes (50c) for the crossing the free ends of the support rod (70) from a pair of occluders (80)； the front face of the primary housing (50) also provides a cut-out for the crossing of a main rod (90), designed for the support of the secondary junction box (51) which has a central light emitter (130) where In turn, a printed circuit board (PCI) is mounted which receives the information from the control (Ct) and base plate (52) provided with limiter (52a) from a pair of articulators (52b) of respective arms (100). Where a set of light-emitting diodes is installed equidistantly? leds? (110)； Is each arm 100 comprised of an arcuate profile whose radius is designed for the gradual arrangement of the LEDs? leds? (110) at angles (a) from 0 ° to 90 ° in order to identify the patient's degree of perception difficulty (p).resumo ?aperfeiçoamentos introduzidos em aparelho para campimetria?. trata-se de um aparelho (10) para campimetria destinado à área oftalmológica e idealizado para a realização de exames de campimetria horizontal monocular proporcionando conforto ao usuário no momento da realização do exame, além de realiza-lo em tempo reduzido； o aparelho (10) para campimetria prevê base (20) onde é instalado ortogonalmente perfil tubular metálico (30) e cuja extremidade oposta (31) é fixada na face inferior (41a) da
