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.

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.

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.

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?

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.

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.
