Proliferative Vitreoretinopathy and Its Impact on Vision - Ophthalmology

More Info

---

Proliferative Vitreoretinopathy (PVR) is a significant complication that can arise after retinal detachment surgery, particularly in cases involving extensive retinal tears or multiple surgeries. It is characterized by an abnormal healing response where retinal pigment epithelial (RPE) cells migrate, proliferate, and transform into fibroblast-like cells, leading to the formation of cellular membranes on the retinal surface. This can result in tractional retinal detachment, which may severely impact vision.

1. Post-Surgery Complications and Symptoms: After undergoing retinal laser treatment, it is not uncommon for patients to experience an increase in floaters, which can be attributed to the changes in the vitreous gel and the potential development of PVR. The strong energy used in laser treatments can indeed contribute to the proliferation of these cells, leading to the symptoms you are experiencing. Floaters are often a result of the vitreous gel pulling away from the retina, and in cases of PVR, the presence of membranes can exacerbate this condition.

2. Understanding Retinal Laser Treatments: Retinal photocoagulation, often referred to as laser treatment, is a procedure used to treat various retinal conditions, including diabetic retinopathy and retinal tears. It involves using laser energy to create small burns in the retina, which helps to seal leaks and prevent further detachment. The term "electrocoagulation" generally refers to a different technique that uses electrical current rather than laser energy.

3. Symptoms of PVR: One of the symptoms associated with PVR is indeed an increase in floaters. These floaters can appear as spots, cobwebs, or strands in your vision, and they may become more pronounced as the condition progresses. If you are experiencing a significant increase in floaters, it is essential to monitor this closely, as it may indicate changes in the vitreous or the development of PVR.

4. Risk of Tractional Retinal Detachment: The concern regarding floaters causing tractional retinal detachment is valid. If the vitreous gel is pulling on the retina, it can lead to tears or detachment. However, not all floaters will cause this issue. It is crucial to have regular follow-ups with your ophthalmologist to assess the condition of your retina and vitreous.

5. Follow-Up and Diagnosis: If your ophthalmologist did not mention PVR during your last examination, it may suggest that they did not observe any signs of this condition. However, if you continue to experience significant floaters or other visual disturbances, it is advisable to seek a second opinion or request a more thorough examination, including a detailed assessment of the vitreous.

6. Comparison of Laser Treatments: The laser treatments for diabetic retinopathy and retinal degeneration may differ in technique and application. Diabetic laser treatment often involves treating a larger area of the retina to prevent further damage, while treatments for retinal tears may focus on specific areas. The number of laser spots used can vary based on the extent of the condition being treated. Your experience of having around 300 laser spots is not uncommon for certain conditions, but the severity of floaters following treatment can vary from person to person.

In conclusion, if you are experiencing significant changes in your vision, including an increase in floaters or any other symptoms, it is crucial to maintain open communication with your eye care provider. Regular monitoring and follow-up examinations are essential to ensure that any potential complications, such as PVR, are identified and managed promptly. If you have concerns about your current symptoms or the implications of your previous treatments, do not hesitate to seek further evaluation.
