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.

Is retinal detachment serious?

Retinal detachment is a very serious disease that affects vision, causing a black fog to appear in front of the eyes that significantly impairs visual function. If retinal detachment is not treated promptly, the eye will gradually lose vision until it finally loses all perception of sight. There are currently three causes of retinal detachment. The common cause is rhegmatogenous retinal detachment, which refers to the appearance of a tear in the retina leading to its detachment. Another type is tractional retinal detachment, commonly seen in diabetic retinopathy and other proliferative retinal disorders, where the retina is pulled away. There is also exudative retinal detachment. All require careful examination by a qualified doctor followed by timely treatment.

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.

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.

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.
