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.

Does nearsightedness imaging fall in front of or behind the retina?

The image in a nearsighted eye forms in front of the retina, whereas in farsighted eyes, the image forms behind the retina. Nearsightedness means seeing clearly up close but blurry at a distance. When nearsighted, appropriate measures such as pupil dilation, optometric examination, and corrective lenses should be taken, or orthokeratology may be used. Once the degree stabilizes and no further progression occurs, surgical treatment can be considered after the age of 18. When the eye is unaccommodative, and parallel light rays enter, they focus in front of the retina. After these occurrences, with proactive treatment and proper rest, efforts should be made to prevent further increase in the degree. Especially in children, attention should also be paid to the development of strabismus and amblyopia.

What is the vision like after the removal of silicone oil for retinal detachment?

Silicone oil is temporarily used to support the retina in our eyes, and its refractive power is roughly equivalent to that of a 600-degree pair of glasses. Thus, if you are not myopic, you might become nearsighted after the silicone oil is used. After the retina detaches and the silicone oil is removed, the vision mainly depends on the function of the retina, which has no relation to the silicone oil. Just as with myopia, wearing a pair of glasses might change the vision, but once the glasses are removed, the vision will revert to the retina's vision. Therefore, it mainly depends on how much vision was left before the retina detached. The recovery of the retinal function and the optic nerve function is related, and this doesn't have much to do with the silicone oil. The vision primarily depends on the remaining function of the retina.

Is retinal detachment a minor surgery?

Retinal detachment surgery is considered major surgery in ophthalmology, where retinal detachment refers to the separation of the retinal neuroepithelium from the pigment epithelium. There are many surgical methods for retinal detachment, including external scleral buckling, internal vitrectomy, gas injection into the vitreous, and the use of silicone oil, among others. Generally, internal procedures carry a greater risk than external ones. Retinal detachments can be categorized into rhegmatogenous retinal detachment and non-rhegmatogenous retinal detachment. Rhegmatogenous retinal detachment usually requires surgical treatment and is commonly seen in cases of high myopia, artificial intraocular lenses, aphakia, and ocular trauma that cause retinal detachment. Non-rhegmatogenous retinal detachment can be divided into tractional retinal detachment and exudative retinal detachment. Tractional retinal detachment often requires surgical treatment, whereas exudative retinal detachment usually 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.

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.
