Early symptoms of cataracts
The early symptoms of cataracts can manifest as day blindness or night blindness. When the cloudiness of the lens originates from the middle of the eye, the strong daylight and illumination can cause the pupil to contract, which then blocks the light from entering the eye, resulting in day blindness. When the cloudiness of the lens is located around the periphery of the eye, the dim light at night cannot reach the peripheral retina, thus causing night blindness. Other early symptoms of cataracts include the following: when the cloudiness of the lens is located at the pupil, patients may see fixed dots or patches of shadow in front of their eyes. However, since cataracts share similar characteristics with floaters, they should be distinguished; the shadows in floaters can move, while the shadows in cataracts are fixed. Varying degrees of blurry vision are also early symptoms of cataracts. Patients may experience gradually increasing blurriness of vision, often perceiving halos around lights or seeing colors of objects as dull and unclear. The early development of cataracts is quite slow and can be determined by the deepest and most obvious part of the lens cloudiness and its development condition.
How is the surgery for nearsightedness?
The choice and design of myopia surgery methods need to be comprehensively considered based on factors such as the patient's preoperative examination results and postoperative vision requirements. Generally, patients can choose laser myopia surgery. If high visual acuity is needed due to study or work, or if there is high physical activity after surgery, it is recommended to choose a safer surgical option. This is because minimally invasive technology causes less trauma to the corneal nerves, which can more effectively improve postoperative night vision, greatly enhance visual quality, and better stabilize postoperative vision.
Early symptoms of glaucoma
Glaucoma is a condition where the intraocular pressure exceeds the tolerance limits of the tissues within the eyeball, especially the optic nerve, causing characteristic optic nerve atrophy and visual field defects. In the early stages of glaucoma, the following symptoms may occur: First, there is eye pain, which may also be accompanied by headaches; Second, transient phenomena of rainbow vision or foggy vision, resembling the appearance of rainbow-like halos around light sources such as light bulbs; Third, there is a family history of glaucoma, especially if suspicious symptoms are present; Fourth, the eyeball becomes harder, and may feel as hard as a stone. Fifth, unexplained decrease in vision or visual field defects. Some glaucomas have atypical early symptoms, but the presence of the above symptoms should be taken seriously and prompt a hospital visit for diagnosis. High-risk groups for glaucoma should undergo annual eye exams to prevent the disease.
How to treat high myopia?
High myopia refers to a degree of nearsightedness above 1000 degrees. High myopia brings great troubles to people, even affecting their diet and preventing them from participating in high-intensity physical exercise. It may also lead to complications such as retinal detachment, cataracts, macular hemorrhage, macular degeneration, vitreous liquefaction degeneration, and glaucoma. The treatment of high myopia has always been a major challenge in ophthalmology. With the advent of refractive lens exchange surgery, after extensive clinical practice, it has now become a better option for correcting vision in patients with extremely high myopia. The refractive state of the eyeball is mainly determined by the refractive power of the eyeball and the length of the eye axis. In cases of nearsightedness, the lengthening of the eye axis causes the light to focus in front of the retina, making it difficult for patients to see distant objects clearly. During refractive lens exchange surgery, a concave lens specifically tailored to the patient is implanted into the eyeball to change the focal point of the light so that it accurately focuses on the retina, achieving the purpose of correcting nearsightedness. Refractive lens exchange surgery maintains the integrity and accommodative function of the eye's physiological structure, has a larger optical zone, eliminates aberrations, and has a wider range of adaptability compared to corneal refractive surgery. Post-surgery, patients experience less discomfort, faster vision recovery, stable refraction, and no regression phenomenon.
Conjunctivitis symptoms
Conjunctivitis is an inflammation that occurs in the thin layer of structure on the surface of the white eyeball and the inner surface of the eyelid. Conjunctivitis can be caused by infections such as bacteria, viruses, chlamydia, fungi, parasites, etc., and by environmental factors like sand, smoke, ultraviolet exposure, and chemical injuries from acids, alkalis, or toxic gases. It can also be an inflammatory response of the conjunctiva due to allergic or systemic diseases including tuberculosis, syphilis, thyroid disorders, or surrounding tissues of the eye such as the cornea, sclera, eyelids, nasal cavity, and sinuses. Common symptoms of conjunctivitis include red eyes, a sensation of a foreign body in the eye, burning, itching, photophobia (sensitivity to light), tearing, and increased discharge. Sometimes it can also cause eye pain.
