Abstract Background: Transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. This study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. Methods: In a ...

PURPOSE Research shows wide variation in macular pigment density between individuals. As are other ocular pigments, this variation may be genetic. To test this hypothesis, the authors measured macular pigment density, serum carotenoid concentrations, and general dietary patterns in 10 pairs of identical twins. METHODS Macular pigment was measured psychophysically by a 1 degree test stimulus. ...

incontinentia pigmenti is a rare inherited disorder involving abnormalities of the skin, hair, eyes, musculoskeletal system, central nervous system, and the teeth. dental abnormalities are the most common manifestations of this disorder. the purpose of this case report was to present the clinical and radiological findings of a seven-year-old girl as well as the results of her five-year follow u...

PURPOSE Increasing evidence implicates macular pigment in protecting the retina and retinal pigment epithelium from light-initiated oxidative damage. Little information, however, is available regarding "average" levels of macular pigment in the general population. This study was designed to assess macular pigment in a high-light environment and to determine what personal characteristics influen...

PURPOSE To map the photopigment distribution of central foveal cones in healthy adult subjects before potential onset of age-related macular degeneration. To compare alterations in cone photopigment distribution to those of macular pigment and examine those loci for subretinal changes. METHODS Eleven healthy subjects (age range, 31-59 years) underwent reflectometry with a scanning laser ophth...

Macular pigment is key to the healthy eye. Direct determination of macular pigment optical density using single-wavelength reflectometry with a fundus camera has allowed to identify changes in macular pigmentation in patients with dry or exudative macular degeneration. This approach could be useful for individualised patient follow-up, particularly in those with age-related macular degeneration.

We present a technique for estimating the density of the human macular pigment noninvasively that takes advantage of the autofluorescence of lipofuscin, which is normally present in the human retinal pigment epithelium. By measuring the intensity of fluorescence at 710 nm, where macular pigment has essentially zero absorption, and stimulating the fluorescence with two wavelengths, one well abso...

Light absorption by macular pigment may attenuate visual discomfort, or photophobia, for targets composed of short-wavelength light. Macular pigment optical density (MPOD) and photophobia light thresholds were measured psychophysically in 10 subjects. The energy necessary to induce photophobia for a short-wavelength target relative to a long-wavelength target was linearly related to MPOD, as we...
