Intravitreal injections deliver medicine directly into the jelly filled cavity of the eye to treat retinal conditions such as macular degeneration, diabetic swelling, and vein occlusions.
Why medicines are injected into the eye
Drugs given as eye drops or tablets often cannot reach the retina in high enough concentrations. Injecting small amounts into the vitreous allows targeted treatment to reduce leakage, swelling, or inflammation and helps protect central vision.
- Common medicines include anti VEGF agents and steroids
- Treatments are usually given as a course over months or longer
- Retinal scans and vision tests monitor response between visits
- Many people maintain or gain vision with ongoing therapy
What happens during and after an injection
The eye is cleaned, numbed with drops, and a small device keeps the lids gently open. A very fine needle then delivers the medicine through the white of the eye.
- You may feel pressure but sharp pain should be brief if present
- Temporary floaters, grittiness, or mild redness are common afterwards
- Serious infection or retinal problems are rare but need urgent attention
- Contact the clinic immediately if you notice severe pain, worsening redness, or sudden vision loss
