Eduardo Arenas, Elena Oudovitchenko Pan Am J Ophthalmol 2007, 6:16 (1 January 2007)
SUMMARY
We present a prospective study analyzing a series of patients with ophthalmic cephalgia, probably induced by an erroneous position of the screen more than five degrees above the level of the sight in VDT users. All patients included in the analysis used the VDT more than 4 hours every day, complained of cephalgia and asthenopia as one of their symptoms and were using the screen computer 15 degrees above eye level. Patients with other causes of cephalgia such as inappropriate refraction, general disorders and use of laptops were excluded. After several weeks and proper positioning of the screen, patients were questioned about their symptoms, and 70% reported a clear improvement. The pathophysiology of this finding called "screen VDT cephalgia" are discussed along with its importance and relevance in the workplace from and ophthalmologic and ergonomic standpoint.
RESUMEN
Se presenta un estudio prospectivo en el que se analizan una serie de pacientes en los que se les sospechó una cefalea oftálmica inducida por la mala posición de uso de los monitores de computador, de acuerdo a un protocolo en el que se recomienda que la altura del mismo este al menos 15 grados por debajo del eje visual. Todos los pacientes incluídos usaban el computador tipo personal por un lapso mayor de 4 horas diarias, tenían cefalea y utilizaban el monitor por encima del eje visual. A todos se les descartó cualquier otra causa oftalmológica o sistémica responsable de la cefalea. Se excluyeron aquellos pacientes usuarios de laptop. La mejoría de los síntomas astenópicos fue del 70% tres semanas o más después de haber corregido la altura de uso del monitor. Se insiste en la importancia desde el punto de vista ocular, laboral y ergológico y se explican las posibles causas fisiológicas responsables de este nuevo síndrome del Monitor.
