Diagnosis of Diabetic Retinopathy

 The diagnosis of diabetic retinopathy begins with a comprehensive eye exam by an eye care professional. During the exam, the eye care professional will dilate the pupils and examine the retina for any signs of damage. In addition to the eye exam, the following tests may be used to diagnose diabetic retinopathy:

  1. Funduscopic examination: This is an examination of the back of the eye using a special instrument called an ophthalmoscope. The eye care professional will look for any signs of swelling or bleeding in the retina.
  2. Fluorescein angiography: This test involves injecting a dye into the bloodstream and taking photographs of the retina as the dye passes through the blood vessels. The dye helps to highlight any abnormalities in the blood vessels, such as leakage or blockage.
  3. Optical coherence tomography (OCT): This test uses light waves to create detailed images of the retina. It can help to detect swelling or thickening in the retina caused by leaking blood vessels.
  4. Retinal photography: This test involves taking photographs of the retina using a special camera. The photographs can be used to track any changes in the blood vessels over time and help to determine the best treatment plan.

It is important for people with diabetes to have regular eye exams to detect diabetic retinopathy as early as possible. Early detection and treatment can significantly reduce the risk of vision loss and help preserve vision.

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...
