We may encounter various kinds of trauma in our life, and one of them is very common is ocular trauma, which is often treated poorly and patients often lose useful vision or even their eyes. Therefore, we would like to introduce some basic knowledge of ocular trauma, which we hope will be of some help to you. There are two types of ocular trauma: open and closed. Closed ocular trauma and the wall of the eye is not ruptured, the ball content is not dislodged, and the eye is still intact. The injury usually does not require emergency treatment, and the patient will be given some time for treatment and consultation, so most patients will get a better prognosis. Open ocular trauma is a common condition in which the wall of the eye is broken and incomplete, which means that the eye is leaking or deflated. Patients often feel terrible when they hear that the eyeball is leaking or deflated, and some doctors often think of the seriousness of the condition and the need to remove the eyeball when they see a ruptured eye. In fact, with the current ophthalmology technology, only very few ruptured eyeballs are considered for removal, and most of them can be preserved or even restore useful vision. We introduce some common open eye injury basics and treatment principles: We divide open eye injuries into three zones according to the extent and severity of wound involvement: Zone I injuries: Wounds involving the cornea and corneoscleral rim: this kind of ocular trauma is relatively light, emergency to the cornea and corneoscleral rim wound watertight suture, restore the integrity of the eye, the intraocular situation is injury-dependent, you can treat the traumatic barrier, iris detachment, pupil together. It can also be treated in two stages. Post-operative observation is usually done, and secondary surgery is considered only if necessary. Zone II injury: The wound is within 5 mm behind the corneoscleral rim, a location that does not usually involve the retina, so the next treatment option should be considered based on what is seen intraoperatively. If a large amount of vitreous detachment is seen intraoperatively, with the retina visible in between, then we perform a second vitreoretinal surgery within 10 after suturing the wall of the eye. If there is only a small amount of vitreous and a little bit of uveal detachment, we need to suture the wall of the eye and observe the eye every two weeks postoperatively. Ultrasound is definitely needed to consider the next step of treatment depending on the situation. Zone II wounds are relatively complex to treat and require careful intraoperative examination to make a proper judgment, and these patients often recover useful vision as well. Zone III injury: The wound involves the corneoscleral rim after 5 mm, more vitreous detachment, and likely retinal detachment. We generally suture the wall of the eye to restore the integrity of the eye first, depending on the situation. Vitreoretinal surgery is performed within 10 days after surgery. The prognosis for patients with Zone III injuries is relatively poor, but most patients can preserve their eyes after several surgeries, and some patients even retain better vision. Patients with ocular trauma are relatively complex and difficult to manage, and require the joint efforts of the medical staff and the patient to achieve good results. We are strongly opposed to emergency removal of the eye, and I often tell subordinate doctors the following phrase: not if you can’t handle it, others can’t, not if it’s not handled well here or elsewhere. Everyone has only two eyes, so don’t give up so easily. Severe open eye trauma can only be known to what extent it is injured and what it will look like in the future after vitreoretinal surgery. That’s why we advise ophthalmologists and patients to be careful, careful, and careful again before making a decision to remove the ball!
