A common in-office procedure is an eye injection for treatment of various eye conditions, such as wet macular degeneration, diabetic retinopathy, or vein occlusion.
It is normal to be anxious prior to your first eye injection but knowing what to expect may alleviate some anxiety.
Your eye will be numbed with topical anesthetic drops. Usually, a cotton-tipped applicator soaked in anesthetic will be held against the white part of the eye to numb it. Sometimes, a thick gel may also be used for numbing. Once the eye is numbed, it will then be cleaned and a small instrument will be used to hold the eye open. During the actual injection, some patients feel pressure while others may feel a quick sting. Each person will have a different experience and each injection will be different.
The medicine is injected into the white part of the eye. Sometimes a blood vessel may be encountered during the injection and you may notice a little redness on the outside of the eye. This is purely a cosmetic symptom and the redness will disappear within the next couple of days. Patients may also experience some mild irritation after the injection due to the drops that are placed in the eye. I usually recommend over-the-counter artificial tears to use after the injections. Usually, the eye should feel normal by the next day.
Another common symptom after an injection are floaters. These floaters usually appear as small bubbles in the lower half of your vision, but they will disappear in in a day or two.
There are no activity restrictions after the injection and no antibiotic drops are needed.
Things to watch for after the injection:
- If your eye gets painful or redness develops a couple of days after the injection, then you should call your doctor.
- If your vision declines or you notice increased or hundreds of floaters then you should call to be seen.
Otherwise, patients are usually initially seen once a month after they first start injections.

We all know that during pregnancy, a woman's body goes through a great deal of change hormonally and physiologically. But did you know her eyes change as well? Below are some of the most common effects pregnancy can have on the eye.
- Corneal changes. In some cases, pregnancy can cause the cornea, the front window of the eye, to change curvature and even swell, leading to shifts in glasses and contact lens prescriptions. In addition, changes in the chemistry of the tear film can lead to dry eyes and contact lens intolerance. It is for these reasons that it is generally not recommended to have any new contact lens fitting or new glasses prescription checks until several months postpartum. We want to get the most accurate measurements possible.
- Retinal changes. Many different conditions can affect the retina during pregnancy. If the pregnant woman has diabetes, diabetic eye disease can progress by 50%. In women with preeclampsia, a condition where blood pressure rises significantly, over 40% of women can show changes in the retinal blood vessels, and 25% to 50% complain of changes to their vision.
- Eye Pressure Fluctuation. Intraocular pressure (IOP) usually decreases during pregnancy. The exact mechanism causing this is unknown, but it is usually attributed to an increase of flow of intraocular fluid out of the eye. This is good news for pregnant women with glaucoma or high IOP. In fact, the drop in IOP is larger when you start with a high IOP compared to one in the normal range.
There are many more effects that pregnancy can have on the eye, but these are the most common. One other thing to keep in mind is that though the likelihood of any adverse effect is extremely low, we try not to use any diagnostic eye drops on pregnant patients during the eye exam. Unless there is a medical necessity to dilate the pupils or check IOP, it is a good rule of thumb to put off using drops until after the patient has given birth in order to protect the developing baby.
