10 layers of Retina

 

  1. Photoreceptor layer: This layer contains the rods and cones, which are responsible for converting light energy into electrical signals.
  2. Outer nuclear layer: This layer contains the nuclei of the rods and cones.
  3. Outer plexiform layer: This layer contains the synapses, or connections, between the rods and cones and the bipolar cells.
  4. Inner nuclear layer: This layer contains the nuclei of the bipolar cells, horizontal cells, and amacrine cells.
  5. Inner plexiform layer: This layer contains the synapses between the bipolar cells and the ganglion cells.
  6. Ganglion cell layer: This layer contains the ganglion cells, which transmit the electrical signals generated by the photoreceptors to the brain via the optic nerve.
  7. Nerve fiber layer: This layer contains the axons of the ganglion cells, which form the optic nerve.
  8. Inner limiting membrane: This is a thin layer of tissue that separates the retina from the vitreous humor, a gel-like substance that fills the inside of the eye.
  9. Choroid layer: This layer is a vascular layer of tissue that lies beneath the retina and provides it with blood flow and nutrients.
  10. Retinal pigment epithelium (RPE): This layer is a layer of cells that sits between the choroid and the retina. It helps to nourish the retina and remove waste products. It also helps to absorb light and protect the retina from damage.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
