PARS PLANA VITRECTOMY

 Pars plana vitrectomy (PPV) is a surgical procedure that is used to remove the vitreous gel, which fills the inside of the eye, from the vitreous cavity. The vitreous is a clear gel-like substance that helps to maintain the shape of the eye and helps to focus light on the retina. Pars plana vitrectomy is used to treat a range of conditions that affect the vitreous and the retina, including retinal detachment, diabetic retinopathy, and complications from previous eye surgery.

Indications:

  • Pars plana vitrectomy is used to treat a range of conditions that affect the vitreous and the retina, including retinal detachment, diabetic retinopathy, macular hole, epiretinal membrane, and complications from previous eye surgery.
  • It is also used to treat vitreous hemorrhage, which is a condition in which bleeding occurs within the vitreous cavity.

Procedure:

  • Pars plana vitrectomy is typically performed under general anesthesia and usually takes about two to three hours to complete.
  • During the procedure, a small incision is made in the sclera, the white of the eye, and a special instrument called a vitrector is inserted into the eye to remove the vitreous gel.
  • In some cases, the surgeon may also use laser therapy or other treatments to repair or remove abnormal blood vessels or other tissue.
  • In some cases, the surgeon may also use a gas or silicone oil to replace the vitreous gel and help to keep the retina in place.

Recovery:

  • After the surgery, the eye may be bandaged and the patient will need to keep the head elevated and avoid any strenuous activity for several days to a week.
  • The eye will be checked frequently to monitor healing and the patient will be given eye drops to reduce inflammation and prevent infection.
  • Recovery time varies depending on the extent of the surgery and the underlying condition, but most patients can return to normal activities within a few weeks.

Complications:

  • As with any surgery, there is a risk of complications with pars plana vitrectomy.
  • These include bleeding, infection, retinal detachment, cataract formation, and loss of vision.
  • However, the risk of complications is low and the procedure has a high success rate in treating the underlying condition.

Pars plana vitrectomy is a safe and effective surgical procedure that is used to treat a range of conditions that affect the vitreous and the retina. It is important to consult an ophthalmologist or retina specialist for proper evaluation and recommendation if you suspect you have a condition that may need a vitrectomy. With proper post-operative care and follow-up, most patients can expect to recover good vision and return to normal activities.

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...
