Clinically, the more common eye diseases mainly include eyestrain, red eyes, night blindness, lazy eye, strabismus and nystagmus, colorblindness, uveitis, presbyopia, floaters, dry eyes, excess tearing, cataracts, glaucoma, retinal disorders, conjunctivitis, corneal diseases, eyelid problems, vision changesproblems with contact lenses. The following will analyze the causes of several common eye diseases.
The causes of eye fatigue are mostly due to prolonged exposure to electronic devices such as computers and mobile phones, incorrect reading posture, and poor personal eye hygiene habits. Generally speaking, in response to this situation, it is recommended that you close your eyes, do eye exercises, massage with the palm of your hand, adjust the brightness and contrast of your phone, etc. If these measures do not relieve the symptoms of eye fatigue, please consult a doctor in time.
Bloodshot eyes are a symptom of conjunctival hyperemia. There are many reasons, the most common are conjunctivitis, staying up late, and dry eye. When the eye is irritated by inflammation, the blood vessels of the conjunctiva will have hyperemia. If it is a bacterial infection, there will be yellow-white secretions. If it is a viral infection, the secretions are usually white. When the virus invades the cornea, the cornea is formed. In inflammation, the eyes will appear as ciliary hyperemia. These conditions require symptomatic medication.
There are many reasons for night blindness. The more common diseases are retinitis pigmentosa, optic neuropathy, late glaucoma, and vitamin A deficiency. Some patients are also seen after panretinal photocoagulation surgery, congenital achoroid disease, progressive vision, cone rod cell dystrophy, drug poisoning and so on.
The strabismus of the eyes is mainly due to congenital development, and then there are special reasons that cause the eyeball to be incorrectly positioned. Its treatment methods mainly include surgical treatment and non-surgical treatment. For strabismus, the younger the age is, the better the effect of surgical treatment is. Surgery is not only to correct the position of the eyeballs and improve the appearance, but more importantly, to establish binocular vision in children. Precision instruments used in eye surgery include ophthalmic surgical instruments cannula or corneal cannula, straight eye dressing forceps, wire eye speculum and Miltex 5-310 eye scissors with probe points.
Presbyopia is a normal physiological phenomenon that occurs with age and is a stage that everyone must go through. In addition to age factors, presbyopia is often related to factors such as reading habits, physical fitness, race, and living environment. Reading glasses, contact lenses, LASIK can be used to restore good reading vision.
Vitreous hemorrhage, retinal detachment, and posterior uveitis are common causes of floating objects in the eye. Doctors will give targeted treatment measures based on a clear diagnosis. If vitreous hemorrhage is large and retinal detachment has occurred, surgery may be required. Miltex 5-310 eye scissors with probe points can play a great role in this kind of surgery. According to different causes of posterior uveitis, corresponding treatments are given. If caused by infection, give anti-infective drugs; because of immune factors, it is best to use immunosuppressive therapy.
Cataract refers to a visually impaired disease caused by decreased transparency or color change of the lens. Its pathogenesis is more complicated, and it is the result of the long-term comprehensive effect of internal and external factors on the lens.
Glaucoma is a disease characterized by optic atrophy, visual field defect, and decreased vision. It can be treated with medication, laser treatment and surgery.
Surgical scissors commonly used in surgical operations include long surgical scissors, medical clamp scissors, and surgical steel scissors.
For different surgical operations, surgical scissors are not exactly the same, such as blunt nose surgical scissors for rhinoplasty and straight eye scissors for eye surgery.
In summary, we can see that surgical treatment is one of the solutions to many eye problems today. In addition to the several eye diseases mentioned above, eyelid problems, vision changes and problems with contact lenses are also commonly treated with surgery.
