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.

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.

Can you take a plane with a detached retina?

Retinal detachment and flying are divided into pre-surgery and post-surgery considerations. Before retinal detachment surgery, it is generally permissible to fly, as this typically does not significantly impact the symptoms of retinal detachment. However, what occurs after the surgery must be considered. If, after surgery, only silicone oil is used as a filler, flying is permissible as it does not affect pressure changes. However, if an inert gas is used as a filler after retinal detachment surgery, it can expand due to changes in air pressure at high altitudes. This expansion increases its volume, which can alter the internal pressure of the eye, potentially compressing the eyeball and the retina, leading to ischemia of the central retinal artery. In such cases, where inert or expansible gases are filled within the eye, flying is not advisable until the gas has dissipated.

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.

Treatment methods for retinal detachment

Retinal detachment surgery primarily refers to the treatment of rhegmatogenous retinal detachment. There are two methods of treatment: one is external surgery, also known as scleral buckling. This involves using a compressive object to indent the sclera to support the choroid, and then employing cryotherapy to create a sterile adhesion between the choroid and the retina, thus treating the retinal detachment. Another method is internal surgery, also known as vitreoretinal surgery. This procedure involves making three incisions in the flat part of the sclera, removing the vitreous from the inside, flattening the retina with heavy water, and using a laser to create a sterile adhesion between the retina and the choroid. Currently, the surgical treatment for retinal detachment consists of these two approaches: internal and external surgeries.

Does retinal detachment cause eye pain?

Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina at the back of the eye. Its main symptoms include flashes of light, blurry vision, and visual obstruction. It is characterized by a painless, sudden decrease in vision. Therefore, patients experiencing retinal detachment will notice flashes of light and a rapid decrease in vision prior to the condition developing, without feeling pain, thus there is no pain associated with retinal detachment.
