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.

Can a retinal detachment be treated after one year?

If retinal detachment is discovered or diagnosed only after a year, the effectiveness of surgical treatment tends to be poorer. However, if there is no eyeball atrophy, no corneal, lens, or vitreous abnormalities at this time, surgery to reposition the retina can still be considered first, followed by assessment of vision recovery. Additionally, an ophthalmic examination should be conducted, including tests like uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular B-ultrasound, and fundus photography, to decide and predict the outcome of the surgery and post-operative conditions. Nevertheless, even if a year has passed since the retinal detachment occurred, active treatment should still be pursued, and one should not give up.

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?

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.

Can you swim after retinal detachment surgery with a lens implant?

Retinal detachment and having an implanted lens means you cannot swim, and if you wish to swim, it must be at least six months later. There are generally two types of surgeries for retinal detachment: vitrectomy with retinal repositioning, and scleral buckling. If a lens has been implanted, it means the natural lens was removed and replaced with an artificial lens. Therefore, after surgery, it is important to rest properly, maintain correct posture, attend timely follow-up appointments, monitor visual recovery and eye pressure, and use eye drops as prescribed.

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.
