What are the symptoms of cataract early?

1, blurred vision

Blurred vision, depending on the material gradually blurred, and sometimes feel the light around the aperture and the color of the object is not bright enough. If the cataract patient is driving at night, there will be a kind of opposite the car headlights too dazzling and feel uncomfortable or irritable feeling. But in general, early cataract symptoms of the development process is quite slow, and depending on the lens of the most turbid location and its development process

2, color vision abnormal

Abnormal color vision, cataract early because the lens absorbs more water and swelling, the epithelial cell gap increases and filled with droplets of water droplets, light through it will occur when the refraction and color halo, commonly known as rainbow.

What are the early symptoms of cataracts?

3, in front of the shadow

Early cataract, part of the lens opacity in the pupil area, in front of the location can be fixed, the shape of the same point or sheet shadow. It is caused by the vitreous opacity of the mosquitoes are different, the latter's shadow is moving, although the scope of activities is not large, but when the hidden, the shape of changeable.

4, day blindness or night blindness

Day blindness or night blindness, if the lens opacity first in the central part of the beginning, daytime light intensity, pupil shrink, the light into the eye blocked, resulting in day blindness; such as the lens opacity in the peripheral part of the evening dark light into the equatorial retina blocked, and Equatorial retinal rod-like cells are liquid-based vision, which will appear fluid blindness, which is one of the early symptoms of cataracts.

5, eye flowers to reduce

Elderly usually need to wear reading glasses to read the newspaper, but they will suddenly find themselves do not need to wear presbyopic glasses see also very clear, and some old happy, in fact, this is not a good sign , This is because the initial cataract early, the lens convexity increased, refractive point near the point of change, is one of the early symptoms of cataracts.

What are the hazards of astigmatism?

1, visual fatigue: astigmatism due to the meridian of the meridian of the different parallel to the refraction of light can not focus on the formation of two focus line, so the brain is very easy to produce the choice of the elephant read. Because the astigmatism is easy to produce on the direction of the focus of the retina of the focal plane of the scene; another astigmatism in order to see the relative view of the scene as much as possible to adjust the size of the circle to reduce the size of the circle to improve the quality of the astigmatism if the correction of improper words Or do not wear a mirror easily lead to headaches. As fatigue and other symptoms, so astigmatism is very easy to produce visual fatigue.

2, amblyopia: more common in a high degree of astigmatism, especially hyperopia astigmatism, because it is not very far from the distance is very clear, vision is not exercise. Prone to amblyopia, followed by the tendency of strabismus

3, what are the hazards of astigmatism? In fact, regardless of the distant objects, as the object, are blurred, the patient often have the habit of narrowing the eyelids into a gap, in an attempt to make the object see more clearly.

4, vision loss: astigmatism away from the retina of the coke line direction of the visual color fades, the edge of the hair is not clear, not easy to identify, decreased vision, severe cases of diplopia. In addition to physiological astigmatism, the various astigmatism are likely to cause vision loss.

What are the symptoms of trachoma?

1, the symptoms

Mostly acute onset, the patient has foreign body sensation, photophobia, tears, a lot of mucus or mucous secretions. A few weeks after the acute symptoms subsided, into the chronic phase, this time without any discomfort or only easy to feel tired. If at this time to cure or self-healing, can not leave scars. However, in chronic disease, in the popular areas, often repeated infection, exacerbations. Corneal with active pannus, the irritation becomes significant, vision loss. Late often due to sequelae, such as eyelid varus, trichiasis, corneal ulcers and dry eye, the symptoms are more obvious, and seriously affect the vision, or even blindness.

2, signs

⑴ acute trachoma: showing the symptoms of acute follicular conjunctivitis, eyelid swelling, conjunctival hyperemia, due to nipple hyperplasia eyelid conjunctiva rough, upper and lower dome conjunctiva follicular follicles, combined with diffuse keratitis and anterior lymphadenopathy. After a few weeks of acute inflammation subsided, to chronic phase.

⑵ chronic trachoma: may be due to repeated infection, duration of several years to more than 10 years. Although the degree of congestion is reduced, but with subcutaneous tissue diffuse cell infiltration, conjunctiva was fouling hypertrophy, while nipple hyperplasia and follicular formation, follicular size ranging from plastic samples can be above the dome and tarsal upper conjunctiva significantly The The same lesion is also found in the lower palpebral conjunctiva and the lower dome conjunctiva, severe cases can even invade half of the wrinkles. Corneal pannus: it is from the cornea outside the normal capillary network, through the corneal limbus into the transparent cornea, affecting vision, and gradually to the pupil area development, accompanied by cell infiltration and development of shallow ulcers, healed after the formation of cornea Small face. Cell infiltration can form a thick flesh-like pannus (pannus crassus).

3, trachoma follicles

In the chronic disease, conjunctival lesions gradually replaced by connective tissue, the formation of scar. The earliest appeared in the upper eyelid conjunctiva under the tarsus, was horizontal white stripes, then gradually reticular, until the active lesions completely subsided, the lesion conjunctiva all become white smooth scar.

4, trachoma scar

The course and prognosis of trachoma, due to the severity of infection and whether the repeated infection is different. Light or no repeated infection, a few months can be more, conjunctival left scar or no obvious scar. Repeated infection of critically ill patients, the course of disease can be lingering for several years to 10 years, chronic diseases, can be infected by other bacteria and repeated infection is often an acute attack. Finally, a wide range of scar is no longer contagious, but there are serious complications and sequelae, often make vision loss, or even blind.

What are the causes of dry eye?

(1) water layer lacrimal tear lacrimal secretion: is the most common cause of dry eye; congenital absence of lacrimal gland aging lacrimal gland, reduced function or some autoimmune diseases caused by lacrimal gland inflammation trauma infection autonomic dysfunction, long-term point of some eye Pills (such as some of the treatment of fatigue glaucoma drugs stop) or taking certain drugs (such as certain high blood pressure medications, etc.) will cause tear secretion is not enough; easy as long as wearing contact lenses due to reduce the sensitivity of the cornea Affect the secretion of each tear.

                            http://www.wehealthweb.com/ophthalmology/
(2) lack of fat layer: due to eyelid disease caused by eyelid sebaceous gland dysfunction.

(3) mucin layer secretion: lack of vitamin A1 chronic conjunctivitis pemphigus chemical burns and so on.

(Such as a long time to concentrate on driving, has been staring at watching TV, computer and reduce the number of blinks) for a long time only in the air-conditioned room work or outdoor strong winds (4) tearing the tear film uneven distribution: eyelid disease caused by poor eyelid blinks The

Myopia treatment methods are what

(1) non-surgical treatment of myopia

Wearing a pair of suitable glasses is the most effective way to treat myopia. Children with myopia, the performance is not lively, on the focus of attention, can not see the blackboard led to decline in academic performance, and sometimes may produce strabismus. If you wear the appropriate glasses of myopia, you can move the image back of the retina, so that the image just fell on the retina, so you can immediately see things, remember not to blindly borrow other people's glasses. In addition, the treatment of myopia can also be through the eye, according to the temple, do massage exercises, add vitamins and so on.

(2) surgical treatment of myopia

Surgical treatment of myopia mainly after scleral reinforcement, excimer laser myopia surgery two methods, excimer laser myopia surgery is the most popular way to treat myopia.

Posterior scleral reinforcement: suitable for the control of high myopia axial extension, the purpose is to control and reduce myopia. For children 8 years before the occurrence of myopia, the prognosis may be poor, so this part of the child can take active surgical treatment. Adult myopia continue to deepen, do posterior scleral reinforcement can prevent the development of myopia, to be stable after a period of time to do other refractive surgery better.

Excimer laser myopia surgery: is a correction of high myopia commonly used surgical procedures, can correct 100-3000 degrees of myopia. Excimer laser surgery requires age over 18 years of age, 2 years no significant change in the degree, and check no surgery contraindications.

What are the hazards of vitreous opacity?

(1) vitreous hemorrhage. What are the hazards of vitreous opacity? Vitreous itself without blood vessels, where the bleeding is foreign, especially to see the retina of large blood vessels, high blood pressure, diabetes, retinal vein plugs and other common in the elderly, trauma is also a common cause. Bleeding, such as long-term non-absorption, can occur in the machine, proliferation, leading to retinal detachment.

(2) vitreous inflammatory exudation. Common in uveitis, suppurative endophthalmitis, sympathetic ophthalmia, syphilitic retinal choroiditis and so on. Examination can be found in the vitreous floating point-like, flocculent inflammatory cells, if serious, may have vitreous empyema, eventually leading to traction retinal detachment.

(3) vitreous pigmentation, can be seen in primary retinal detachment, endophthalmitis, trauma and so on. What are the hazards of vitreous opacity? Pigment particles may be derived from the retinal pigment layer or intravitreal hemorrhage.

(4) intraocular tumors. Infants and young children the most common intraocular malignant tumor is retinoblastoma, and reticulocyte sarcoma is found in the elderly, will lead to vitreous opacity.

(5) vitreous parasites in the vitreous body can also lead to vitreous opacity to pigs, tapeworm cercariae most common, although the age group can occur, but there are obvious regional distribution tendencies. What are the hazards of vitreous opacity? Once the cysticercosis release toxins, can cause severe vitreous opacity, retinal detachment.
