Medical & Surgical Retina

Medical and surgical retina is a subspecialty within ophthalmology that focuses on the diagnosis and treatment of diseases affecting the retina and vitreous. The retina is a thin layer of tissue located at the back of the eye that is responsible for converting light into signals that are sent to the brain, allowing us to perceive visual images. The vitreous is a gel-like substance that fills the inside of the eye.

Conditions that fall under the purview of medical and surgical retina include:

Age-related macular degeneration (AMD): A progressive condition that affects the macula, the central part of the retina responsible for sharp, central vision.

Diabetic retinopathy: A complication of diabetes that affects the blood vessels of the retina, leading to vision impairment and blindness if left untreated.

Retinal detachment: A serious condition where the retina pulls away from its normal position, leading to vision loss if not promptly treated.

Macular holes and epiretinal membranes: Conditions where there are abnormalities in the macula, causing distortion or loss of central vision.

Retinal vascular diseases: Conditions such as retinal vein occlusion or retinal artery occlusion, which affect the blood vessels of the retina.

Retinal tears and breaks: Structural abnormalities in the retina that can lead to retinal detachment if left untreated.

Treatment options for these conditions may include:

Medical therapy: This can involve the use of medications, such as anti-VEGF injections, steroids, or immunosuppressive agents, to manage conditions like AMD, diabetic retinopathy, or retinal vascular diseases.

Laser therapy: Laser treatment may be used to seal leaking blood vessels in diabetic retinopathy, treat retinal tears, or reduce abnormal blood vessel growth in conditions like AMD.

Surgical intervention: Surgical procedures such as vitrectomy may be necessary for conditions like retinal detachment, macular holes, or epiretinal membranes. During a vitrectomy, the vitreous gel is removed and replaced with a saline solution.

Regular eye examinations are essential for the early detection and management of retinal diseases, as many of these conditions can cause irreversible vision loss if left untreated. If you have any concerns about your vision or retinal health, it's important to consult with an ophthalmologist, particularly one specializing in medical and surgical retina.

Intravitreal injections and retinal laser treatments are common procedures used to manage various eye conditions, particularly those affecting the retina.

Here's an overview of each:

Surgical options:

  • Purpose
    Intravitreal injections deliver medication directly into the vitreous, the gel-like substance inside the eye, to treat conditions such as age-related macular degeneration (AMD), diabetic retinopathy, and macular edema.
  • Types of Medications:
    Common medications include anti-vascular endothelial growth factor (anti-VEGF) drugs, steroids, and antibiotics, depending on the specific condition being treated.
  • Procedure
    The procedure is typically done in an office setting. The eye is numbed with local anesthesia, and the medication is injected into the vitreous using a fine needle. Patients may need multiple injections over time, depending on the condition's response to treatment.

Retinal Laser Treatment:

  • Purpose
    Retinal laser treatment is used to treat a variety of retinal conditions, including diabetic retinopathy, retinal tears or detachments, and certain types of macular disorders.
  • Types of Laser Treatments:
    Common medications include anti-vascular endothelial growth factor (anti-VEGF) drugs, steroids, and antibiotics, depending on the specific condition being treated.
    • Panretinal Photocoagulation (PRP):
      Used to treat proliferative diabetic retinopathy by creating scattered laser burns in the peripheral retina to reduce abnormal blood vessel growth.
    • Focal/Grid Laser Treatment:
      Targets specific areas of the retina, such as leaking blood vessels in macular edema or abnormal blood vessels in AMD, to seal or shrink them.
    • Laser Retinopexy:
      Used to treat retinal tears by creating a laser seal around the tear to prevent fluid from entering and causing a retinal detachment.
  • Procedure :
    During the procedure, the patient may receive numbing eye drops, and a special contact lens may be placed on the eye to help focus the laser. The ophthalmologist then uses a laser to deliver precise bursts of light to the targeted areas of the retina.

Both intravitreal injections and retinal laser treatments are effective in managing various retinal conditions. The choice of treatment depends on factors such as the specific condition, its severity, and the patient's overall eye health. These procedures are typically performed by retina specialists or ophthalmologists with expertise in retinal diseases. Regular follow-up visits and monitoring are essential for patients undergoing these treatments.
