Moreover, the stabilization does not appear to be permanent and the drug cannot repair already-damaged retinal tissue.

It is not yet clear why these abnormalities will cause incomplete development of the brain, achlorhydria, and failure in the maintenance of retinal tissue.

The intensity of light at each point on the image corresponds to the pattern of blood vessels surrounded by the brighter reflection of retinal tissue.

Caution should be exercised in treatment with laser surgery since it causes a loss of retinal tissue.

Until this study in 2005, we only knew about the inflammation of the retinal tissue causing AMD, not the genes responsible.

Retinal dysplasia is characterized by folds or rosettes (round clumps) of the retinal tissue.

These limitations have prompted studies of a more selective treatment that can knock out damaging blood vessels without harming the surrounding retinal tissue.

That's recognizable retinal tissue, there, with rods and cones.

The early images allow for the recognition of autofluorescence of the retinal tissues.

The retinal tissue has to heal first.
