Floater syndrome and retinal detachment generally have no necessary connection.

Floater syndrome is the clouding of the vitreous body. Mild vitreous clouding does not affect vision and manifests as floating objects in front of the eyes. Pathological vitreous clouding that affects vision requires further examination by an ophthalmologist, including an ocular B-ultrasound to diagnose the extent of the vitreous clouding, and proactive treatment should be administered.

Retinal detachment generally involves the separation of the retina from the choroid. Once a clear diagnosis of detachment is made, active treatment should be pursued promptly to restore vision as soon as possible. If the treatment is delayed, it can easily lead to retinal atrophy, resulting in the shrinkage of the eyeball.

How to perform surgery for retinal detachment?

Firstly, there are three types of retinal detachment: rhegmatogenous, tractional, and exudative retinal detachment. For rhegmatogenous and tractional retinal detachment, surgical treatment is generally adopted. There are two common surgical methods: one is external surgery, known as scleral buckling, and the other is internal surgery, involving vitrectomy with complex retinal detachment repositioning. The choice of surgical method requires assessment by an ophthalmology specialist before a decision can be made. Exudative retinal detachment is generally treated by addressing the underlying disease and does not require surgery.

Does retinal detachment cause eye pain?

After retinal detachment, there is usually no pain in the eye. Symptoms include low ocular pressure, blurred vision, and visual field defects, which means seeing things partially or missing a half. In such cases, it is important to actively seek an ophthalmological examination. This includes checking the uncorrected visual acuity, corrected visual acuity, intraocular pressure, eye ultrasound, and fundus photography. Once diagnosed, it is crucial to undergo surgery as soon as possible. The earlier the surgery is performed, the better the potential recovery of vision. Generally, there is a high possibility of restoring vision after surgery.

What is the vision like after the removal of silicone oil for retinal detachment?

Silicone oil is temporarily used to support the retina in our eyes, and its refractive power is roughly equivalent to that of a 600-degree pair of glasses. Thus, if you are not myopic, you might become nearsighted after the silicone oil is used. After the retina detaches and the silicone oil is removed, the vision mainly depends on the function of the retina, which has no relation to the silicone oil. Just as with myopia, wearing a pair of glasses might change the vision, but once the glasses are removed, the vision will revert to the retina's vision. Therefore, it mainly depends on how much vision was left before the retina detached. The recovery of the retinal function and the optic nerve function is related, and this doesn't have much to do with the silicone oil. The vision primarily depends on the remaining function of the retina.

When is the second surgery for retinal detachment?

The question you asked is about when the second surgery for retinal detachment should take place, which implies that the first surgery for retinal detachment failed, necessitating a second surgery. Due to the proliferation of the retina, which generally peaks around two to three weeks, it is recommended that if the first surgery fails, the second surgery should be conducted about 10-14 days after the first surgery, which is about half a month later. This timing can help reduce the failure rate of the surgery and avoid the peak proliferation period of the retina.

Can retinal detachment heal by itself?

Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina. Based on its cause, it can be categorized into rhegmatogenous retinal detachment, tractional retinal detachment, and exudative retinal detachment. Rhegmatogenous retinal detachment requires repositioning of the retina and closure of the break. If it is tractional retinal detachment, it is necessary to remove the cause, generally requiring vitrectomy and retinal reposition surgery. Exudative retinal detachment generally occurs due to inflammation or other irritations causing exudation or bleeding in the retina, resulting in detachment, typically without retinal breaks. This type of retinal detachment only requires treatment for the underlying disease, and aggressive treatment of the primary disease can generally lead to a cure. Therefore, retinal detachment must be treated; it cannot heal on its own.
