Sclerotomy

Sclerotomy

A sclerotomy is a surgical procedure that involves making an incision into the sclera, the white outer coating of the eyeball. This procedure is commonly performed in various ophthalmic surgeries, particularly in the treatment of retinal detachment and other vitreoretinal disorders.

Indications

Sclerotomy is indicated in several ophthalmic conditions, including:

• Retinal Detachment: To provide access for the repair of a detached retina.
• Vitreous Hemorrhage: To allow for the removal of blood from the vitreous cavity.
• Macular Hole: To facilitate the surgical repair of a hole in the macula.
• Epiretinal Membrane: To enable the peeling of membranes from the retinal surface.

Procedure

The sclerotomy procedure involves the following steps:

1. Anesthesia: The patient is typically given local or general anesthesia, depending on the complexity of the surgery and patient factors. 2. Incision: A small incision is made in the sclera, usually with a microvitreoretinal (MVR) blade. The location of the incision is carefully chosen to avoid damage to the retina and other ocular structures. 3. Insertion of Instruments: Surgical instruments, such as a vitrector or endoilluminator, are inserted through the sclerotomy to perform the necessary intraocular procedures. 4. Closure: After the procedure, the sclerotomy may be closed with sutures or left to self-seal, depending on the size of the incision and the surgeon's preference.

Complications

While sclerotomy is generally safe, potential complications include:

• Infection: Endophthalmitis is a rare but serious infection that can occur postoperatively.
• Bleeding: Hemorrhage can occur during or after the procedure.
• Retinal Detachment: The procedure itself can sometimes lead to retinal detachment.
• Hypotony: Low intraocular pressure can result if the sclerotomy does not seal properly.

Postoperative Care

Postoperative care is crucial to ensure proper healing and to monitor for complications. Patients are typically prescribed topical antibiotics and anti-inflammatory medications. Follow-up visits are scheduled to assess the healing process and visual recovery.
