IRIDOTOMY

 Iridotomy is a surgical procedure that involves creating a small hole in the iris, which is the colored part of the eye that surrounds the pupil. The procedure is typically performed to treat angle-closure glaucoma, a condition in which the iris blocks the drainage angle in the eye, causing an increase in intraocular pressure. In this article, we will discuss the indications, preparation, procedure, and recovery of iridotomy, as well as potential risks and complications.

Indications for Iridotomy

Iridotomy is typically indicated for angle-closure glaucoma, a condition in which the iris blocks the drainage angle in the eye, causing an increase in intraocular pressure. This increase in pressure can lead to damage to the optic nerve and vision loss. Iridotomy can be performed to create a hole in the iris, allowing the fluid to flow out of the eye and decrease the pressure.

Preparation for Iridotomy

Before the procedure, the patient will have a thorough eye exam to check their vision and eye health. They will also have a discussion with the surgeon about the risks and benefits of the procedure, as well as the expected recovery time. The patient will be instructed to stop taking blood-thinning medications for several days before the procedure, and may be given eye drops to dilate the pupils.

Procedure for Iridotomy

Iridotomy is typically performed under local anesthesia, and the procedure typically takes about 30 minutes. The procedure can be done in two ways:

  1. Surgical iridotomy: A small incision is made in the cornea, and a portion of the iris is removed using a surgical instrument called an iris scissors.
  2. Laser iridotomy: A laser is used to create a hole in the iris, which allows the fluid to flow out of the eye and decrease the pressure.

Recovery after Iridotomy

After the procedure, the eye will be patched and the patient will be instructed to rest and avoid strenuous activities for several days. They will also be given eye drops to prevent infection and reduce inflammation. The patient will have follow-up visits with the surgeon to monitor their recovery and check for any complications.

Potential Risks and Complications

As with any surgical procedure, there are potential risks and complications associated with iridotomy. These include:

  1. Infection
  2. Bleeding
  3. Damage to the cornea or other parts of the eye
  4. Loss of vision
  5. Recurrence of the original condition

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...
