“…Crosssectional studies of RNFL thickness using scanning laser polarimetry also have found a decrease in RNFL thickness with age. [9][10][11][12] The human RNFL loses approximately 5000 axons per year from birth to death, approximately 2500 per year before age 50 and 7500 per year after 50. 3 It is not surprising, then, that RNFL thickness decreases with age.…”

“…1,4,5 Previous studies have shown that NFLT measurements are useful to distinguish glaucoma patients from normal and ocular hypertension patients, and that NFLT decreases with the increasing severity of glaucoma. [6][7][8][9][10][11] However, with the previous version of the nerve fiber analysis program, it was not possible to make an analysis of the NFLT divided into the upper and lower regions on the horizontal meridian. Thus, most of the reports on NFLT and visual field defects heretofore were obtained from the relationship between RNFL THICKNESS IN POAG AND NTG the relative ratio of NFLT divided into four quadrants (superior, inferior, temporal, and nasal) and the mean deviation (MD), and not based on the relationship between the absolute value of the NFLT and the visual field defects.…”

“…Esta birrefringência se deve à disposição paralela dos microtúbulos nos axônios daquelas células. A luz polarizada passa através da CFN retiniana, sofrendo um retardo que é proporcional à espessura da CFN.Esta correlação foi demonstrada através de estudos anatomopatológicos em macacos que tiveram suas córneas e cristalinos removidos 2 , e em olhos humanos intactos 1,3 .Estas estruturas podem porém, in vivo, polarizar a luz, afetando os resultados.Com o objetivo de minimizar estes efeitos, foi incorporada ao aparelho a luz com espectro infravermelho (780nm), e um dispositivo que compensa a polarização causada por aquelas estruturas birrefringentes.Vários estudos mostram ser a análise da CFN pela polarimetria a laser um método promissor e com aplicabilidade clínica [4][5][6] .Neste estudo, objetivamos determinar a especificidade do analisador de fibras nervosas em um grupo de pacientes não glaucomatosos (denominados normais), assim como os índices que mais freqüentemente são causa Descritores: Fibras nervosas; Especificidade; Técnicas de diagnóstico oftalmológico; Lasers/uso diagnóstico. …”
