Retinal detachment can also be treated with laser therapy.

Retinal detachment is a common eye disease and a type of fundus disease. It is usually caused by eye trauma, or the development of dry breaks or degenerative areas in the peripheral retina.

Patients with retinal detachment experience symptoms such as shadows obstructing parts of their vision, distorted vision, and decreased visual acuity. If the area of detachment is small, it can be treated with laser therapy to seal off the detached area, thereby preventing the condition from worsening.

If the area of retinal detachment is large, it cannot be cured with laser therapy alone. Surgical treatment is needed to reposition the retina, and during surgery, laser treatment is also necessary to seal the tears or deformed areas on the retina to prevent recurrence of the detachment.

Is vitreous floaters close to retinal detachment?

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.

Can a retinal detachment be treated after one year?

If retinal detachment is discovered or diagnosed only after a year, the effectiveness of surgical treatment tends to be poorer. However, if there is no eyeball atrophy, no corneal, lens, or vitreous abnormalities at this time, surgery to reposition the retina can still be considered first, followed by assessment of vision recovery. Additionally, an ophthalmic examination should be conducted, including tests like uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular B-ultrasound, and fundus photography, to decide and predict the outcome of the surgery and post-operative conditions. Nevertheless, even if a year has passed since the retinal detachment occurred, active treatment should still be pursued, and one should not give up.

Is retinal detachment a minor surgery?

Retinal detachment surgery is considered major surgery in ophthalmology, where retinal detachment refers to the separation of the retinal neuroepithelium from the pigment epithelium. There are many surgical methods for retinal detachment, including external scleral buckling, internal vitrectomy, gas injection into the vitreous, and the use of silicone oil, among others. Generally, internal procedures carry a greater risk than external ones. Retinal detachments can be categorized into rhegmatogenous retinal detachment and non-rhegmatogenous retinal detachment. Rhegmatogenous retinal detachment usually requires surgical treatment and is commonly seen in cases of high myopia, artificial intraocular lenses, aphakia, and ocular trauma that cause retinal detachment. Non-rhegmatogenous retinal detachment can be divided into tractional retinal detachment and exudative retinal detachment. Tractional retinal detachment often requires surgical treatment, whereas exudative retinal detachment usually does not require 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.

Can you swim after retinal detachment surgery with a lens implant?

Retinal detachment and having an implanted lens means you cannot swim, and if you wish to swim, it must be at least six months later. There are generally two types of surgeries for retinal detachment: vitrectomy with retinal repositioning, and scleral buckling. If a lens has been implanted, it means the natural lens was removed and replaced with an artificial lens. Therefore, after surgery, it is important to rest properly, maintain correct posture, attend timely follow-up appointments, monitor visual recovery and eye pressure, and use eye drops as prescribed.
