As an ophthalmologist, there is no greater sense of fulfillment and happiness than to be infected by the intense joy that passes through a patient the moment he or she removes the gauze and sees the light again. As an ophthalmologist who has worked for more than 20 years and operated on nearly 20,000 patients, this sense of joy often haunts me. However, the recent admission of a patient with ocular trauma has made me feel that I have the heart to ask for help, but I am powerless to do anything about it! A week ago, a tall, thin, middle-aged male patient walked into my office and said that his left eye had been suffering from recurring redness and pain for a month, and that he had bought some eye drops for himself, which did not help much, and that’s why he wanted to come to the hospital for a checkup. Detailed history, he said six years ago when playing stone seems to have something splashed in the eye, because the vision is not affected, so did not pay attention, nearly a year vision slowly decline but did not pay attention to it, thought it was the cause of age. This month, it has obviously worsened. Listening to him say here my heart has a foreboding, when in the slit lamp to see the patient’s eyes the moment, confirmed my speculation. This is what kind of eye ah, just can see the light in front of the eyes, the cornea is very cloudy, the interlayer and the cornea after a large number of rust deposits, the iris is like about to be crumpled up yellow paper, hanging there lifelessly, there is no reaction to the light, the surface of the surface is also adhering to a piece of dark-colored objects, as if the rust, and the surrounding tissues are connected very tightly, the crystalline all mixed with the over-ripe cataract, the posterior part of the eye can not see the situation at all. I immediately reacted that it was an iron foreign body. A series of special examinations confirmed my diagnosis: intraocular foreign body, ferruginous. I couldn’t help but be saddened by the fact that this eye trauma patient had missed the best time for treatment. Six years of rust covering the entire eyeball had severely impaired the eye’s visual function, and even with surgery, it was impossible to restore vision. In order to save the eye, he was given intraocular foreign body removal combined with cataract surgery after three days of anti-inflammation. During the surgery, he encountered an unexpected situation that made the surgery very difficult: the whole iris and lens were like rotten mud completely different from normal cataracts. The foreign body and cataract were carefully removed and the abnormal tissues were clearly cleaned, but it was not possible or necessary to implant an IOL. Iron rust had severely impaired the patient’s visual function, and the surgery merely saved the eye. If he had taken his injury seriously and treated it in a timely manner, he would have gotten the opposite result. Ocular trauma is a common disease in ophthalmology, with complex etiology, complicated treatment methods, and outcomes that cannot be directly predicted. The timing and treatment of ocular trauma directly determines the outcome of the injured eye. Especially metal foreign body into the eye, must be removed as soon as possible, iron, copper and other metals can lead to rust, copper rust, invasion of multiple tissues in the eye and seriously affect the visual function. Some may even develop sympathetic ophthalmia and affect the other eye. In production, life should pay attention to protect the eyes, once the eye trauma, should be timely and correct treatment: chemical injury (acid or alkali) should be as soon as possible to the nearest rinse with water, and then sent to the hospital. Occurrence of mechanical eye trauma, must promptly seek medical attention. In case of open wounds, avoid squeezing and applying eye ointment, and send to the hospital as soon as possible after applying a hard cardboard box cover for simple protection. Time is light, don’t wait until the light disappears to know how to pay attention!
