Retinal 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.
Can retinal detachment heal by itself?
Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina. Based on its cause, it can be categorized into rhegmatogenous retinal detachment, tractional retinal detachment, and exudative retinal detachment. Rhegmatogenous retinal detachment requires repositioning of the retina and closure of the break. If it is tractional retinal detachment, it is necessary to remove the cause, generally requiring vitrectomy and retinal reposition surgery. Exudative retinal detachment generally occurs due to inflammation or other irritations causing exudation or bleeding in the retina, resulting in detachment, typically without retinal breaks. This type of retinal detachment only requires treatment for the underlying disease, and aggressive treatment of the primary disease can generally lead to a cure. Therefore, retinal detachment must be treated; it cannot heal on its own.
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.
Does retinal detachment cause eye pain?
Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina at the back of the eye. Its main symptoms include flashes of light, blurry vision, and visual obstruction. It is characterized by a painless, sudden decrease in vision. Therefore, patients experiencing retinal detachment will notice flashes of light and a rapid decrease in vision prior to the condition developing, without feeling pain, thus there is no pain associated with retinal detachment.
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.
Can retinal detachment be treated with laser?
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.
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.
Is vitreous floaters close to retinal detachment?
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.
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.
