Vitreous hemorrhage after laser treatment?


My mother suddenly noticed many black spots in her vision and went to a clinic for evaluation.
The clinic physician diagnosed her with a retinal tear and performed laser treatment.
She experienced some improvement in the days following the laser procedure.
However, her vision suddenly became blurry again recently.
Upon returning for a follow-up, the doctor mentioned vitreous hemorrhage and recommended a B-scan at a larger hospital.
At Chang Gung Hospital, the doctor examined her with an ophthalmoscope and decided she needed another laser treatment, but did not perform the B-scan.
After the laser treatment, the doctor advised her to return for a follow-up in a week, but her vision remains very blurry.
Is this normal? Should she return for an earlier follow-up? Thank you for your response.

Hello Sun: When the vitreous body pulls on the retina and causes a tear, the release of pigment cells beneath the retina and bleeding from the torn blood vessels at the edge of the tear can lead to a significant increase in floaters and blurred vision.
Laser treatment is performed around the tear to encircle it and prevent further retinal detachment.
However, the blood vessels at the edge of the tear may continue to bleed, causing blood to flow into the vitreous body, resulting in blurred vision.
The laser does not remove the blood from the vitreous, so temporary blurred vision will persist until the blood gradually settles or is absorbed, at which point vision will improve.
Please follow your doctor's instructions for follow-up visits.
In Taiwan, the ophthalmology department at Puzi Hospital is open: Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM, and Wednesday from 2:00 PM to 4:30 PM.
Online responses are for reference only; if necessary, you should seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.

Post-laser vitreous hemorrhage can be a concerning condition, especially when accompanied by symptoms such as sudden changes in vision. In your mother's case, it appears that she underwent laser treatment for a retinal tear, which is a common procedure aimed at preventing further complications, such as retinal detachment. The initial improvement in her vision following the laser treatment is a positive sign, but the subsequent return of blurry vision and the presence of vitreous hemorrhage raises some important considerations.

Vitreous hemorrhage occurs when blood leaks into the vitreous cavity of the eye, often as a result of retinal tears or other underlying conditions. After laser treatment, it is not uncommon for patients to experience some degree of blurred vision as the eye heals. The recovery process can vary significantly from person to person, and several factors can influence the duration and extent of visual recovery.

1. Healing Process: After a vitreous hemorrhage, the body typically reabsorbs the blood over time. This process can take several weeks to months, depending on the amount of blood and the individual’s healing response. During this time, vision may fluctuate, and it is not unusual for patients to experience periods of clarity followed by blurriness.

2. Follow-Up Care: It is crucial for your mother to follow her doctor's recommendations regarding follow-up appointments. If her vision remains blurry or worsens, it is advisable to contact her healthcare provider sooner than the scheduled follow-up. Persistent blurriness could indicate that the hemorrhage is not resolving as expected or that there may be other complications requiring attention.

3. B-scan Ultrasound: The recommendation for a B-scan ultrasound is typically made to assess the status of the retina and vitreous in cases of significant hemorrhage. If the doctor at Chang Gung Hospital suggested another laser treatment without performing the B-scan, it may be worth discussing the rationale behind this decision. A B-scan can provide valuable information about the presence of any retinal detachment or other issues that may not be visible during a standard eye examination.

4. Symptoms to Watch For: If your mother experiences any new symptoms, such as increased floaters, flashes of light, or a sudden decrease in vision, these could be signs of complications that require immediate medical attention. It is essential to be vigilant and proactive in monitoring her condition.

5. Patient Education: Understanding the nature of vitreous hemorrhage and the expected recovery timeline can help alleviate anxiety. It is important for patients and their families to have realistic expectations about the healing process and to communicate openly with healthcare providers about any concerns.

In summary, while some blurriness after laser treatment for vitreous hemorrhage can be normal, it is essential to monitor the situation closely. If your mother’s vision does not improve or worsens, it would be prudent to seek an earlier follow-up appointment. Open communication with her healthcare team will ensure that she receives the appropriate care and support during her recovery.
