How to perform Posterior Chamber Examination?

 he posterior chamber is the space behind the iris (the colored part of the eye) and in front of the lens and the vitreous humor (the clear gel-like substance that fills the back of the eye). It is filled with aqueous humor, a clear fluid that helps maintain the shape of the eye and provides nutrition to the structures within the eye. The posterior chamber is an important part of the eye and any abnormalities in its shape or depth can indicate the presence of certain eye conditions.

One way to assess the posterior chamber is through a posterior chamber examination. This can be done during a routine eye examination or when a patient has symptoms such as redness, pain, or decreased vision.

There are several methods for performing a posterior chamber examination, including:

  1. Direct ophthalmoscopy: This method involves using a handheld ophthalmoscope to examine the eye. The ophthalmoscope allows the practitioner to see the front and back of the eye, including the posterior chamber.
  2. Slit lamp examination: A slit lamp is a specialized microscope with a light attached to it. It allows the practitioner to examine the front of the eye, including the cornea, iris, and anterior chamber, in great detail. The practitioner will typically use a narrow beam of light (called a "slit") to examine the eye and can adjust the width and intensity of the beam as needed. While the slit lamp cannot directly examine the posterior chamber, it can be used to assess the iris and the angle between the iris and the cornea, which can provide information about the health of the posterior chamber.
  3. Fundus examination: This method involves using an ophthalmoscope or a specialized camera called a fundus camera to examine the back of the eye, including the posterior chamber. The practitioner will shine a light into the eye and use the ophthalmoscope or fundus camera to view the inside of the eye and assess the health of the posterior chamber and other structures.

During the examination, the practitioner will look for any abnormalities in the shape or depth of the posterior chamber, as well as the presence of any foreign bodies or other abnormalities within the chamber. The practitioner will also assess the iris and pupil for any abnormalities and may test the patient's eye movement and reaction to light.

It is important for the patient to remain still during the examination and to follow the practitioner's instructions. The practitioner may ask the patient to look in different directions or to focus on a specific object.

After the examination, the practitioner will discuss the findings with the patient and may recommend further testing or treatment if necessary.

Posterior chamber examination is an important part of eye care and can help identify and diagnose a variety of eye conditions. It is important for individuals to have regular eye exams to ensure the health of their eyes and 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...
