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.

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.)
Can nearsightedness with astigmatism undergo laser surgery?
Myopia and astigmatism are common eye diseases that are two different types of refractive errors but often occur together. Patients with both myopia and astigmatism who are over 18 years old and have stable prescriptions for more than a year can undergo laser surgery treatment. During the laser surgery, both myopia and astigmatism can be corrected simultaneously. Before undergoing surgery, patients need to visit the ophthalmology department of a hospital for an in-person consultation and examination. The exact degrees of myopia and astigmatism are determined through refraction tests, while corneal topography and ophthalmic ultrasound are used to assess the corneal curvature and thickness to determine if the patient is suitable for corrective laser surgery.
Will strabismus get worse if not operated on?
Strabismus left untreated may either worsen or remain stable. Strabismus is a common eye condition where the eyes do not look in the same direction. When one eye looks directly at an object, the other eye may be misaligned. Depending on the direction of the misalignment, strabismus can be classified into different types such as esotropia, exotropia, and hypertropia. Moreover, based on the different causes of strabismus, it can be divided into accommodative strabismus, paralytic strabismus, concomitant strabismus, and restrictive strabismus. Patients need to visit the ophthalmology department of a hospital for a comprehensive strabismus examination to diagnose the specific type of strabismus, and then receive the corresponding treatment to improve symptoms. For example, accommodative strabismus can be corrected with glasses to adjust refractive errors, thereby eliminating the symptoms of strabismus, while non-accommodative strabismus may require surgical treatment for a cure.
How long will it take for photophobia from keratitis to recover?
Keratitis presents with symptoms of photophobia and generally recovers about two weeks after treatment. Keratitis is a common ophthalmic disease caused by neglect of eye hygiene or external eye injuries, leading to infection in the sclera of the eye. The main symptoms include conjunctival congestion, redness, pain, foreign body sensation, photophobia, tearing, and decreased vision. It is necessary to promptly treat with antibiotic eye drops to eliminate the infection and alleviate the symptoms mentioned. Commonly used medications include levofloxacin hydrochloride eye drops, tobramycin eye drops, and moxifloxacin eye drops. During the treatment period, patients must pay attention to eye hygiene and avoid dirty water entering the eyes to prevent worsening of the infection.
Is night blindness a recessive genetic disease?
Night blindness is not a recessive genetic disease; it is merely a symptom caused by many ophthalmic diseases. The primary manifestation is difficulty seeing in dim environments and requiring a longer time to adapt when moving from bright to dim settings. There are various causes of night blindness, with common ones including vitamin A deficiency, malnutrition of rod cells, and advanced glaucoma. Therefore, when a patient exhibits symptoms of night blindness, it is crucial to seek medical attention promptly. A doctor can determine the specific cause through a comprehensive examination and implement targeted treatment. The primary diseases causing night blindness are mostly non-hereditary; for example, vitamin A deficiency is mainly related to malnutrition and picky eating, which can be treated by supplementing vitamin A.
Can people with night blindness see things at night?
Individuals with night blindness can still see at night, but with less clarity compared to those with normal vision. Night blindness can be caused by various conditions, such as advanced glaucoma, retinal pigment degeneration, Vitamin A deficiency, and poor nourishment of the rod cells in the retina. It occurs due to damage to the rod cells on the retina, which are responsible for dark vision, preventing them from functioning normally. Diagnosis can be confirmed through dark adaptation tests and electroretinography at an ophthalmology department in hospitals. Treatment for night blindness should be based on the underlying cause; for instance, if caused by Vitamin A deficiency, the condition can be treated by supplementing Vitamin A, thus either restoring health, or preventing and slowing further deterioration of the condition.
Is it normal for keratitis to occur every year?
Keratitis is a common ophthalmic disease, occurring as an infection in the black eyeball area of the eye. Recurrent viral keratitis is a normal phenomenon, as the virus can remain dormant within the corneal nerve fibers even after recovery. Triggers such as fatigue, colds, or weakened immunity can cause the virus to replicate again, leading to a recurrence of keratitis. Symptoms include eye congestion, redness, stinging, foreign body sensation, photophobia, tearing, and decreased vision. Doctors use a slit-lamp microscope to observe the cornea, where dendritic or map-like lesions can be seen. Treatment involves using antiviral eye drops to alleviate symptoms, such as acyclovir eye drops, ganciclovir eye drops, and interferon eye drops.
