<p><span style="color: #00826a;"><strong>Intravitreal Injection</strong></span> is an injection of a drug group called anti-VEGF into the vitreous humor, which is a widely accepted and commonly used method for treating various retinal diseases, including wet age-related macular degeneration, diabetic macular edema, macular edema from retinal vein occlusion, and abnormal retinal neovascularization.</p>
<h2><span style="color: #00826a;">Preparation Before Receiving Intravitreal Injection</span></h2>
<ol>
<li>Patients can continue their usual routine, especially taking regular medications such as antihypertensives and blood thinners <span style="color: #00826a;"><strong><u>without stopping the medication</u></strong></span></li>
<li>Bring all medications you are currently taking on the day of the intravitreal injection</li>
<li>Inform the doctor and nursing staff beforehand if you have any of the following symptoms: eye discharge, red eyes, fever, or cough, as there is a higher risk of infection</li>
<li>The nurse will measure blood pressure, body temperature, pulse, respiratory rate, visual acuity, and intraocular pressure before the injection</li>
</ol>
<h2><span style="color: #00826a;">Procedure for Intravitreal Injection</span></h2>
<ol>
<li>Administer anesthetic drops to the patient, including the antiseptic povidone iodine</li>
<li>Clean the area around the eye with povidone iodine</li>
<li>Cover the face with a special cloth and use a tool to hold the eyelids open</li>
<li>Inject the medication into the vitreous humor through the white part of the eye</li>
<li>After the injection, visual acuity and any complications may be reassessed</li>
</ol>
<h2><span style="color: #00826a;">Post-Injection Care</span></h2>
<ol>
<li>Avoid rubbing the eyes. Prevent water or foreign substances from entering the injected eye. Clean the face by wiping with a clean damp cloth instead of washing the face. You may shower and brush your teeth as usual but be careful not to get water in the eye for 3-5 days as advised by the doctor</li>
<li>If you experience eye pain, take 500 mg of paracetamol, 1 tablet each time, with intervals of about 4-6 hours. If after taking paracetamol twice the pain does not subside or if you experience radiating pain to the back of the head, nausea, or vomiting, see a doctor immediately</li>
<li>Possible complications after intravitreal injection include:
<ul>
<li>Seeing black spots or round bubbles floating in the visual field of the injected eye, which usually resolve within 2-3 days</li>
<li>Subconjunctival hemorrhage, which usually resolves within 7-10 days</li>
</ul>
</li>
<li>See a doctor immediately if you notice green eye discharge, swelling, redness, severe pain, worsening vision compared to before the injection, or light sensitivity in the injected eye</li>
<li>Attend all scheduled follow-up appointments to monitor treatment progress</li>
</ol>
<h2><span style="color: #00826a;">Patients Who Should Use Anti-VEGF with Caution</span></h2>
<ul>
<li>Patients with a history of stroke or transient ischemic attack (TIA)</li>
<li>Those at high risk as assessed by the Stroke Score Card of the National Stroke Association</li>
<li>Patients with other risk factors should receive information to help make an informed decision before starting treatment</li>
</ul>
