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.

Symptoms of secondary retinal detachment

The symptoms of a secondary retinal detachment are actually not much different from the first detachment; it's like a fixed shadow. Therefore, if you have ever experienced retinal detachment, you can cover one eye and use the other eye to check the visible range. Remember what range you can see now and then pay attention to any changes in the future. This way, you can clearly understand the changes in your field of vision. In the early stages, there may be an increased sensation of flashing lights or some floating dark shadows, so if these symptoms appear, it is important to go to the hospital for an examination.

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.

What does a detached retina feel like?

The professional term for retinal detachment is "retinal detachment." It primarily refers to the separation between the neuroepithelial layer and the pigment epithelial layer of the retina. Early manifestations of retinal detachment may include mild vision loss, accompanied by floaters, flashes of light, or a shadow that obscures vision. As the condition progresses, symptoms gradually worsen, and when the macular area of the retina is involved, significant vision loss occurs.

Retinal detachment refers to the condition where the retina pulls away from its normal position.

The structure of the human eye consists of three layers: the sclera, the choroid, and the retina. Retinal detachment is not actually a separation between the retina and the choroid, but rather a separation between the neural epithelial layer and the pigment epithelial layer of the retina, which means it is a detachment between the inner nine layers and the outermost layer of the retina. Retinal detachment can be classified into three types: rhegmatogenous retinal detachment, which is mainly caused by a tear in the retina allowing the vitreous fluid to enter the subretinal space; tractional retinal detachment, which occurs due to vitreous and retinal proliferation exerting traction on the retina, commonly seen in diabetic retinal detachment; and exudative retinal detachment, which is caused by accumulation of fluid between layers due to abnormal choroiditis.

Causes of Retinal Detachment

Retinal detachment can be categorized into three main types: rhegmatogenous, tractional, and exudative. Rhegmatogenous retinal detachment is commonly seen in the elderly, highly myopic individuals, those having undergone trauma to the eye leading to the absence of the natural lens or having artificial lens implants, and those with a history of retinal detachment or a family history of the condition, which are risk factors. Tractional retinal detachment is caused by proliferative membranes pulling on the retina. It is observed in conditions like diabetic retinopathy, central retinal vein occlusion, and other ischemic retinal diseases leading to neovascular membranes, or due to proliferative scarring from penetrating eye injuries. Exudative retinal detachment typically occurs in conditions such as Coat’s disease, uveitis, and malignant hypertension.
