retina

(ˈrɛtɪnə)
n, pl -nas or -nae (-ˌniː)
(Anatomy) the light-sensitive membrane forming the inner lining of the posterior wall of the eyeball, composed largely of a specialized terminal expansion of the optic nerve. Images focused here by the lens of the eye are transmitted to the brain as nerve impulses

n., pl. ret•i•nas, ret•i•nae (ˈrɛt nˌi)
the innermost coat of the posterior part of the eyeball that receives the image produced by the lens, is continuous with the optic nerve, and consists of several layers, one of which contains the rods and cones that are sensitive to light.

Diffuse Retinal Thickening due to Epiretinal Membrane in a Patient with Idiopathic Parafoveal Telangiectasia.
The Blue Reflectance (BR; 488nm) predominantly displays the particulars of the Inner Retina and the Vitreoretinal Interface such as the Macular pigment changes, Retinal nerve fiber layer thinning and the Epiretinal membranes.
Exclusion criteria were as follows: History or evidence of any ocular disease such as age-related macular degeneration, diabetic retinopathy, central serous chorioretinopathy, epiretinal membrane, and macular dystrophy; best-corrected visual acuity of <20/25; history of intraocular surgery, trauma, and ocular inflammation; evidence of glaucoma; and poor image due to cataract, refractive errors (myopia or hyperopia) >3 dpt, and astigmatism >1.5 dpt.
They had the same success rate in eyes with concurrent epiretinal membrane (ERM) (5 out of 6 eyes, 83%) and in eyes previously treated with ocriplasmin (5 out of 6 eyes, 83%) (16).
retinal venous occlusive disease, the epiretinal membrane and vitreomacular traction, infectious chorioretinal inflammatory conditions, and posterior segment complications of anterior segment surgery.
The epiretinal membrane (ERM) is an avascular proliferative fibrous tissue composed of extracellular matrix and a polymorphous population of cells, which develops between the vitreous and the internal limiting membrane (ILM).
In this study, cataract and epiretinal surgeries are considered [10].
To minimize the diffuse distribution, researchers separated the vitreous cavity from the retina [3]; however, a thin cluster along the epiretinal membrane was formed at 2 days after surgery.
In mice, LAMA1 was shown to be expressed in the internal limiting membrane (ILM) between the retina and the vitreous body and in Bruch's membrane of the choroid, and it was reported that LAMA1 deficiency could cause abnormal cell adhesion and migration, leading to altered retinal angiogenesis, persistent vitreal fibroplasias, epiretinal membrane formation, and peripheral retinal degeneration [15, 16].
Complications such as macular hole, retinal detachment, epiretinal membrane formation, and persistent premacular cavity may develop after Nd:YAG laser treatment [3].
Laser-induced damages to the macula include outer retinal disruption, foveal hemorrhage, macular edema, epiretinal membrane, full thickness macular hole, etc.[sup][1],[2] There are some case reports of visual improvement following the use of oral corticosteroids, but till date, there is no known effective treatment for this condition.[sup][3],[4] We report a case series of laser-induced maculopathy treated with standard doses of oral corticosteroids.
