VITREO RETINAL PROCEDURES Intravitreal Injection antibiotics

An intravitreal injection is a technique that involves injecting a medicine straight into the vitreous cavity, which is filled with a jelly-like fluid called vitreous humour gel in the back of the eye. In most cases, the operation is carried out in the office by a skilled retina expert.

Intravitreal injections are used to deliver drugs to the retina to treat a number of disorders. The most prevalent disorders treated with intravitreal anti-VEGF medications are age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusion. In certain eyes with diabetic retinopathy, retinal vein blockage, or uveitis, intravitreal steroids are administered.

Anti-VEGF medicines and steroids aid in the reduction of fluid leakage caused by these illnesses. Patients with infections of the eye, such as endophthalmitis and retinitis, are treated with antibiotics, antifungal, and antiviral medicines. In rare situations, a tiny gas bubble is injected into the eye to help in the healing of a retinal detachment.

Disease Overview:

Age-related macular degeneration (AMD)

AMD (age-related macular degeneration) is an eye condition that causes central vision blurring. It occurs when the macula — the region of the eye that regulates crisp, straight-ahead vision — is damaged as a result of ageing. The macula is located in the centre of the retina (the light-sensitive tissue at the back of the eye).

Disease Signs and Symptoms:

• Vision that is hazy or blurred.
• Recognizing familiar faces is difficult.
• Lines that are supposed to be straight seem wavy.
• In the centre of vision, a dark, empty space or blind spot emerges.
• Central vision loss, which is required for driving, reading, recognising faces, and close-up work.

Disease Causes:

Dry AMD is characterised by the formation of tiny yellow deposits called drusen underneath the retina. These are the retina's collected waste products, which can expand in size. This can cause the light-processing retinal cells in the macula to die, resulting in impaired vision.

Disease Diagnosis:

• An Amsler grid is a visual field test that consists of a grid of straight lines with a huge dot in the centre.
• Eye drops dilate (or enlarge) your pupils during a dilated eye test.
• Fluorescein angiography: A yellow dye called fluorescein is injected into a vein in your arm by your healthcare professional.

Disease Treatment:

Although there is no cure, visual aids can assist to lessen the impact on your life. Find out what it's like to live with AMD. Wet AMD — To keep your vision from deteriorating, you may require frequent eye injections and, in rare cases, a light treatment called photodynamic therapy.
