Macular Vascular Density Analysis Using Adobe Photoshop Software In Diabetic Eyes: Optical Coherence Tomography Angiography Study.

Background: Optical Coherence Tomography Angiography (OCTA) is dye less microvascular visualizing technique. In study we binaries OCTA images of macular vessels in healthy and diabetic subjects without macular oedema using Adobe Photoshop CS3 extended version.

Methods: Prospective, single centered, observational study total of 58 eyes of 108 Diabetic Retinopathy (DR) subjects and 20 eyes of 40 normal subjects with mean age of 58.

[Relationship between gender and posterior pole choroidal thickness in normal eyes].

Objective: To investigate and compare the choroidal thickness between healthy male and female subjects.

Method: Six-hundred and twenty eyes of 310 healthy volunteers with no ophthalmic disease history were recruited, including 152 males and 158 females. All volunteers were subgrouped into Group A to F according to their ages.

[Intervention of nicotinamide on skin melanin genesis after UVA exposed].

Objective: To investigate the interference effect of nicotinamide on UVA-induced melanin genesis and melanin transport in human skin melanocyte.

Methods: The optimum UVA dose expected to cause cell proliferation: 0.2 J/cm(2), nicotinamide was added immediately after the 0.

[The intervention of nicotinamide on skin melanocyte's cell proliferation after UVA (365 nm) exposed.].

Objective: To investigate the interference effect of nicotinamide on UVA-induced cell proliferation in human skin melanocyte.

Methods: To apply the optimum UVA dose expected to cause cell proliferation: 0.2 cm2, nicotinamide was added after the 0.
