Will strabismus worsen if it is not treated?
Strabismus, if not treated, can potentially deteriorate over time. Strabismus is a common ocular disease, often caused by congenital developmental anomalies or external injuries to the eye, leading to misaligned visual axes. It can affect the appearance of the patient and may lead to complications such as amblyopia, as well as symptoms like double vision. Currently, surgery is the primary treatment method. The operation adjusts the position of the eye muscles' attachments and alters the tension of the eye muscles, thereby restoring the normal positional relationship between the eyes and aligning their visual axes. Patients need to visit the ophthalmology department of a hospital for an in-person examination and undergo comprehensive strabismus testing to determine the specific surgical plan. Without treatment, the degree of strabismus may continue to increase, leading to a worsening of symptoms.
Can high myopia with astigmatism be treated with surgery?
High myopia combined with astigmatism can also be treated surgically, but it requires the patient to be at least 18 years old, and both the myopia and astigmatism must have been stable for over a year without worsening. Before undergoing surgical treatment, a detailed eye examination is necessary. This includes an optometric examination to accurately measure the degree of myopia and astigmatism, a corneal topography test, and an ophthalmic ultrasound to understand the corneal curvature and thickness. Based on these parameters, a specific surgical plan is designed. If the patient’s corneal condition allows, laser surgery is the preferred method for correction. If the patient’s corneal condition is poor and not suitable for laser surgery, correction and treatment can be achieved through the implantation of a posterior chamber intraocular lens in phakic eyes.
How to treat trachoma stage 2?
Trachoma stage two requires treatment with antibiotic eye drops to kill the Chlamydia infecting the conjunctival tissue, thus alleviating symptoms. Commonly used eye drops include rifampicin, sodium sulfacetamide, and levofloxacin hydrochloride. Trachoma is a common eye disease caused by poor eye hygiene, such as rubbing the eyes with dirty hands, sharing personal hygiene items like basins and towels with others, or using unclean water to wash the face. It is imperative to treat the infection with medication as quickly as possible and to develop good eye hygiene habits to prevent the condition from worsening or spreading to family and friends. If trachoma is not treated promptly, it could lead to complications such as entropion, dry eye syndrome, and corneal vascularization. (Please follow medical advice regarding medication.)
Crystalline astigmatism is caused by what?
Lenticular astigmatism is a common eye disease, usually caused by the early formation of cataracts, where the lens becomes unevenly opaque. This leads to inconsistent refractive power in different directions, causing astigmatism. Patients can visit the ophthalmology department of a hospital for an optometry examination and a slit lamp microscope examination to confirm whether the astigmatism is due to the lens. For lenticular astigmatism, if the cataract has little impact on vision, it can initially be corrected by wearing glasses to improve vision. If the cataract has already significantly affected vision, cataract surgery can be performed to correct and treat it. After the surgery, the lenticular astigmatism will naturally disappear, and the patient’s vision will be improved.
Early symptoms of night blindness
Night blindness is a common early symptom of eye diseases, manifested by blurred vision in dim environments. When transitioning from bright to dark environments, it takes a longer time to gradually adapt. There are many causes of night blindness, such as common ones including vitamin A deficiency, malnutrition of rod cells, and advanced glaucoma. If symptoms of night blindness occur, it is necessary to visit an ophthalmologist in a hospital soon for diagnostic evaluation to determine the specific cause. For night blindness caused by vitamin A deficiency, recovery can be promoted by taking oral vitamin A capsules. There is currently no effective treatment for night blindness caused by malnutrition of rod cells. For those caused by advanced glaucoma, surgical treatment is needed to delay or prevent the progression of the condition.
How can children with minor astigmatism recover?
Mild astigmatism in children refers to astigmatism below 150 degrees, which can impact vision. Currently, once the degree of astigmatism is established, there are no effective non-surgical treatments available to reduce it. Since children cannot immediately undergo surgery to correct astigmatism, the alternative is to wear frame glasses or rigid corneal contact lenses to correct their vision and enhance their eyesight. In subsequent life, it's important to develop good eye habits, avoid squinting when looking at things, not use the eyes at close range for extended periods, and try to prevent the degree of astigmatism from increasing. After reaching adulthood, astigmatism can be corrected through laser surgery.
What should I do if trachoma causes entropion and trichiasis?
Trachoma is a common ophthalmic disease caused by Chlamydia infection of the conjunctival tissue of the eye, resulting in inflammation. Trachoma can lead to substantial scarring of the conjunctiva. As scar tissue contracts, it can cause the eyelids to curl towards the eyeball, leading to entropion and trichiasis. Initially, it is necessary to use antibiotic eye drops to eliminate the Chlamydia infection and prevent the condition from worsening. Commonly used treatments include Levofloxacin eye drops, Rifampicin eye drops, and Sulfacetamide Sodium eye drops. Once the infection is completely eliminated, surgical correction of the entropion can be performed to alleviate the irritation caused by trichiasis to the patient's eyeball. (Please use medication under the guidance of a doctor.)
Night blindness will have what impact?
Night blindness is a common ophthalmological symptom, primarily characterized by poor vision in dim environments. Many factors can cause night blindness, such as advanced glaucoma, retinal pigment degeneration, vitamin A deficiency, etc. It is crucial to seek timely ophthalmic examination at a hospital to diagnose the specific cause of night blindness and then implement targeted treatments. Otherwise, the condition may gradually worsen. For example, night blindness caused by advanced glaucoma can progressively lead to blindness. If night blindness caused by a deficiency in vitamin A is not treated in time, it can also lead to dry eye syndrome, keratomalacia, and other issues. Regarding treatment, night blindness caused by vitamin A deficiency can be treated with oral vitamin A capsules. For night blindness caused by advanced glaucoma, surgical treatment to reduce eye pressure is necessary to halt the progression of the condition.
Corneal inflammation, should I use hot or cold compresses for swollen eyes?
Keratitis is a common ophthalmic disease, referring to inflammation occurring at the corneal part of the eye. It can be caused by bacterial, viral, fungal, amoebic infections, or autoimmune reactions. Patients with keratitis will experience reactive eyelid edema and conjunctival swelling. In terms of treatment, it is first important to avoid rubbing the eyes, as this can exacerbate the swelling. Alternatively, applying a cold towel can help reduce swelling. Cold compresses lower the temperature of eye tissues, causing the capillaries to constrict and thereby reducing the leakage of fluid into the tissue spaces, which facilitates the reduction of eye swelling. Generally, after cold compresses and anti-infection treatments, the inflammation in the eye will completely subside, and the swelling will disappear.
Is it useful to wear glasses for night blindness?
Patients with night blindness cannot improve their symptoms by fitting glasses. Fitting glasses is mainly used to correct refractive errors, such as myopia, hyperopia, astigmatism, etc., whereas night blindness is not caused by refractive errors. It is usually caused by the following reasons: First, it may be caused by retinal pigment degeneration, for which there is currently no effective treatment. Avoiding strong light stimulation can help delay the progression of the disease. Second, it may be caused by late-stage glaucoma, which requires treatment with medication or surgery to reduce eye pressure in order to stop and delay the progression of the disease. Third, it may be caused by malnutrition of the rod cells, related to genetic factors, for which there is also no effective treatment available. Fourth, it may be caused by a lack of vitamin A, which can be treated by taking vitamin A capsules orally. (Please follow medical advice when using medication.)
