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.

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.

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.

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.

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.

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.
