- October 7, 2022
IVOM eye side effects are an important issue that understandably raises questions and concerns for many patients. IVOM therapy (intravitreal surgical drug administration) is a highly effective and often sight-preserving treatment for diseases such as wet macular degeneration (AMD). As your treating ophthalmologist in Frankfurt, Dr. Mareen Schmidt is committed to informing you not only about the great opportunities, but also openly and transparently about the potential side effects and risks. A deep understanding of these aspects is the basis for a trusting and cooperative treatment decision.
Classification of IVOM eye side effects: Common and harmless vs. rare and serious
In the discussion about IVOM eye side effects it is crucial to distinguish between very common but generally harmless side effects and very rare but serious complications. The overwhelming majority of patients tolerate the treatment excellently. The vast majority of side effects are temporary and do not affect the final result. Our entire treatment process, guided by the 5-S method, is designed to reduce all risks to an absolute minimum and offer you the greatest possible safety.
Frequent, mostly harmless side effects after IVOM injection
Immediately after the injection, various side effects may occur, which may be noticed but usually disappear by themselves after a short time. These are normal reactions of the eye to the minor procedure.
- Redness of the eye: A small, harmless hemorrhage can often be seen under the conjunctiva at the puncture site. This red spot sometimes looks dramatic, but is merely a small bruise that disappears on its own within one to two weeks.
- Foreign body sensation: A feeling as if there is a grain of sand or an eyelash in the eye is normal in the first few hours after the procedure. This is caused by the disinfection and the tiny wound on the conjunctiva.
- Perception of „bubbles“ or „streaks“: The injected medication can be perceived as small, moving dots or bubbles in the field of vision for the first one to two days. These dissolve by themselves.
- Slight feeling of pressure or tearing: The eye may be slightly irritated and watery after treatment.
These typical and harmless IVOM eye side effects are no cause for concern and usually do not require special treatment.
Rare but serious IVOM eye side effects to look out for
Although extremely rare, there are serious complications whose early signs you should be aware of. Quick action is crucial here. If the following symptoms occur, you must immediately contact us or the ophthalmologic emergency service:
- Severe, increasing pain in the eye.
- A clear, increasing reddening of the entire eye.
- A sudden and severe deterioration in vision.
- The perception of a „curtain“, „shadow“ or „rain of soot“.
These symptoms may indicate one of the rare but serious IVOM eye side effects such as an infection inside the eye (endophthalmitis) or a retinal detachment. Our strict sterile treatment conditions reduce the risk of infection to an absolute minimum.
IVOM eye side effects in comparison: harmless vs. alarm signals
The following table is intended as a practical guide to help you better classify your symptoms after treatment. If in doubt, please always contact us.
Symptom after the injection | Probable cause (usually harmless) | Possible alarm signal (immediate notification required!) |
Slight scratching / foreign body sensation | Reaction to disinfectant, small puncture wound. | Severe, throbbing, increasing pain. |
Red spot on the white of the eye | Small, harmless hemorrhage of the conjunctiva. | Severe, diffuse redness of the entire eye, often associated with pain. |
Blurred vision immediately afterwards | Ointment residue, disinfectant, the medication in the vitreous humor. | Severe, sudden and increasing visual deterioration hours or days later. |
Small, moving dots / bubbles | The injected medication itself. | Sudden appearance of „soot rain“ (many small dots) or a large shadow. |
Slight sensitivity to light | Temporary irritation of the eye. | Severe sensitivity to light in combination with pain and redness. |
