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 کاملLong-term results after limited macular translocation surgery for wet age-related macular degeneration
PURPOSE To evaluate the long-term results of limited macular translocation (LMT) surgery with radial chorioscleral outfolding in patients with wet age-related macular degeneration (AMD) and subfoveal choroidal neovascularization (CNV). In addition, to identify the factors associated with the final best-corrected visual acuity (BCVA). METHODS The medical records of 20 eyes of 20 consecutive pa...
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 کاملA portable instrument for measuring macular pigment with central fixation.
PURPOSE To evaluate the reliability and validity of a portable instrument for measuring macular pigment optical density. METHODS The instrument is small, uses light emitting diodes as light sources and the principles of heterochromatic flicker photometry of comparing foveal and extra-foveal minimum flicker matches. It uses central fixation for the extra-foveal matches, which subjects found ea...
متن کاملFixation stability, fixation location, and visual acuity after successful macular hole surgery.
PURPOSE This study examined whether changes in fixation stability and fixation location are good predictors of visual acuity after successful macular hole surgery. METHODS Ten patients with macular hole were tested before surgery and at 1 and 3 months after surgery. Visual acuity was measured with the ETDRS; fixation stability and fixation location were assessed with the MP-1 Microperimeter (...
