Post-Vitreous Surgery: Addressing Concerns About Shadows - Ophthalmology

Share to:

Retinal detachment surgery


Hello Doctor, I would like to ask you about my condition.
I underwent a vitrectomy two months ago, and since then, I have been seeing a small shadow in my vision.
I have been diligently lying down, hoping the shadow would disappear, but it has actually grown larger and obstructs my sight.
Eventually, the shadow dispersed into smaller floating spots that move around when I shift my gaze.
It has not disappeared to this day, and I feel very anxious.
Is this situation normal?

It is recommended that you return to the original hospital for an examination, as it is not possible to determine if there are any abnormalities based solely on your description.

After undergoing a vitrectomy, it is not uncommon for patients to experience visual disturbances, including the appearance of shadows or floaters. These symptoms can be concerning, especially when they seem to worsen over time. In your case, the presence of a small shadow that has expanded and transformed into multiple smaller moving shadows can be attributed to several factors related to the surgery and the healing process.

Firstly, during vitrectomy, the vitreous gel that fills the eye is removed. This gel can sometimes pull on the retina, leading to the formation of new floaters or shadows as the eye adjusts to the absence of the vitreous. These floaters are typically harmless and may diminish over time as the eye heals. However, if they are accompanied by flashes of light or a sudden increase in the number of floaters, it could indicate a more serious issue, such as retinal detachment, which requires immediate medical attention.

The fact that you are experiencing an increase in the size and number of these shadows is concerning. While some changes in vision can be expected post-surgery, a significant worsening of symptoms should prompt a thorough evaluation by your ophthalmologist. It is essential to rule out any complications, such as retinal detachment or other issues that may arise after vitrectomy.

Your doctor may recommend regular follow-up appointments to monitor your condition closely. These appointments often include imaging tests, such as wide-angle photography or optical coherence tomography (OCT), to assess the status of the retina and ensure that it remains attached and healthy. The frequency of these follow-ups is crucial, especially in the early stages after surgery, to catch any potential complications early.

In terms of your specific situation, the shadows you are seeing could be related to the healing process or the formation of new floaters. However, it is essential to communicate your concerns with your ophthalmologist, especially if the shadows are affecting your daily life or causing you significant anxiety. Your doctor can provide reassurance and guidance on what to expect during your recovery.

Additionally, it is important to follow your doctor's instructions regarding post-operative care, including any recommendations for positioning (such as lying face down) to promote proper healing and retinal attachment. While it may be uncomfortable, adhering to these guidelines can significantly impact your recovery.

In summary, while some visual disturbances after vitrectomy can be normal, the worsening of shadows should be evaluated by your ophthalmologist. Regular follow-ups and open communication with your healthcare provider are key to ensuring a successful recovery. If you have any further questions or concerns, do not hesitate to reach out to your doctor for clarification and support. Your vision and peace of mind are paramount, and your healthcare team is there to help you navigate this challenging time.
