Macular pigment and age related macular degeneration.
The present concepts of the pathogenesis of AMD include cumulative light damage by oxidative processes in the macular photoreceptors as environmental co-factor for the development of AMD. The direct causative connection of this hypothesis has still to be established but wide circumstantial evidence from epidemiological and basic scientific investigations are strongly supportive. Macular pigment...
متن کاملMacular pigment distribution in Stargardt macular disease.
PURPOSE To investigate macular pigment optical density (MPOD) and distribution in patients with Stargardt disease. METHODS Prospective observational case series. The study included 13 eyes of 13 consecutive patients. A modified confocal scanning laser ophthalmoscope (SLO, Heidelberg, Germany) was used for MPOD measurement. It calculated the MPOD at 0.5° of the center of the fovea, and MPOD in...
متن کاملMacular pigment shows ringlike structures.
PURPOSE The spatial distribution of macular pigment is generally assumed to monotonously decrease to very low values in the periphery. However, there are indications that this picture may be too simple. The purpose of this study was to examine the spatial distribution of the macular pigment optical density. METHODS Fundus reflectance and autofluorescence maps at 488 and 514 nm Argon laser wav...
متن کاملMacular pigment and ocular biometry
This study is designed to investigate the relationship between macular pigment optical density (MPOD) and ocular biometric parameters. The following details were recorded for 180 healthy subjects: demographic profile; best-corrected visual acuity; refractive status; ocular biometric parameters [axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and vitreous chamber depth (VCD)...
متن کاملMacular pigment deposits in rhegmatogenous retinal detachment.
This is a study of 20 cases of macular migration after operation for retinal detachment. The frequency of pigment deposits on the macula among the total number of operated detachments was 6.4%. The evolution of pigment migration depened on the form and type of the deposits. In some cases the pigment diminished or disappeared. In 6 of the 20 eyes with pigment migration puckering of the macula oc...
