White dots in the eyes usually appear against the background of various pathological changes in the structures of the visual organs. This phenomenon may be a consequence of a variety of diseases.
So, ophthalmic diseases have a disappointing tendency to rejuvenation - now almost a third of all patients with impaired vision are preschool children and adolescents. The rest is represented by people of middle and old age. The high-risk group includes those who have congenital eye diseases, does specific work, and is regularly exposed to the harmful effects of toxic fumes, gases, and chemical compounds.
In the people, the white dot in the eye is often called a thorn. This pathology has long been surrounded by all sorts of myths with mystical principles. However, in reality, vice often leads to visual impairment, up to complete blindness. Especially when it comes to the white point in the pupil of the eye. Such a pathology carries a significant danger not only for vision, but also for the entire health of the visual system.
Causes of the white dot in the eye
There may be several prerequisites for the development of such a problem. To identify them, it is necessary to undergo an ophthalmological examination.
The localization of the white point in the eye can be different: pupils, cornea, vitreous body and other structures. The causes of pathology are not so many. Taking into account the location, it is possible to determine the presence of predisposing factors, which often relate to the work of the brain, heart, blood vessels, nervous system.
Leukoma
In the normal state, the cornea has a convex shape and an absolutely transparent texture. A disease such as leukoma leads to a modification of healthy tissue into connective tissue. A place with transformed tissue ceases to function, changes fibrically, which leads to the appearance of a shapeless scar.
A leukoma is a white spot, sometimes with a milky tint, which is located on the surface of the eye. The closer the growth to the pupil, the faster the vision falls. With abnormal tissue transformation, there is a constant overgrowth of scars.
Flies before the eyes
This phenomenon is a consequence of destruction in the structures of the vitreous body. In normal condition, it has a transparent texture, a jelly-like consistency.
The vitreous body is located in the entire cavity of the eye, helps maintain a healthy spherical shape, controls the elasticity of muscle fibers. Often, the disease is interconnected with existing vascular pathologies. In this case, the colorless structure of the vitreous body changes to connective tissue, gradually becoming cloudy.
The main causes of the defect include the following factors:
- neck osteochondrosis;
- excessive physical activity;
- dystonia of vegetovascular origin;
- atherosclerotic processes;
- hypertension;
- avitaminosis.
Retinal detachment, traumatic brain injury, eye damage, hemorrhage - all these conditions can lead to the appearance of flies and white spots on the surface of the cornea.
Abnormal changes in the lens
The appearance of white dots in the eyes is often a harbinger of cataracts. The clouding of the lens ranges from cream to deep gray. Cataracts can be congenital or acquired. Most often, the pathology is diagnosed in the elderly. The problem can be resolved conservatively and surgically. In the advanced state, the patient is prescribed an operation during which the damaged lens is removed and an intraocular lens is implanted.
Reconstruction in corneal structures
A white spot on the cornea of the eye may not affect the visual capabilities of a person. The normal transparent structure of the shell is replaced by a cloudy fabric. Pathology can be generalized or local. With a pronounced abnormal process, visual impairment gradually occurs.
Corneal opacity can be explained by many factors:
- syphilis;
- chronic form of conjunctivitis;
- keratitis;
- infectious diseases;
- tuberculosis of any type.
Any pathology of the eye of an inflammatory nature can lead to the appearance of white dots. The influence of toxins, chemical and thermal burns, various injuries - all this can very well provoke the appearance of an eyesore.
Retinal Modification
White dots in the eye on the iris are formed against a background of insufficient blood supply to the tissues. Doctors call this condition retinal angiopathy. Pathology develops due to:
- any injuries - mechanical, chemical, thermal;
- atherosclerosis of blood vessels;
- hypertension.
In addition, the defect can occur against the background of diabetes mellitus, hypotension and other diseases. Harmful habits can also lead to a deterioration in the blood supply to the eye. Together with the appearance of white dots in the eye, patients may complain of pain, visual impairment.
Other manifestations of the problem
In addition to the white dot in the eye, patients may also complain of blurred vision, blurred, which is caused by a disturbed process of refraction of the rays. In addition, a person with such a problem may experience excessive lacrimation, a feeling of the presence of a foreign object, conjunctival hyperemia.
If the white point is localized in the center of the eye, visual acuity decreases.
Diagnostics
Which doctor should I contact if white dots appear in my eye? The first thing you need to go to the ophthalmologist. The doctor will conduct several clinical studies, starting with a study of the symptoms, interviewing the patient and collecting the necessary medical history.
To identify the causes of the appearance of a white dot and prescribe further treatment in the clinic "New Look", patients are invited to a series of examinations:
- assessment of refraction of the eyeball;
- determination of the visual field;
- Fundus ultrasound;
- measurement of intraocular pressure;
- assessment of the condition of the eye vessels;
- a thorough examination of the eyeball with a microscope;
- measurement of the depth of the structures of the cornea.
Among other things, it is recommended to diagnose hidden diseases, as well as determine the general condition of the visual apparatus. Passing all stages of the examination is necessary to prescribe appropriate therapy and exclude other pathologies of the internal organs.
How to treat
If the white dot that appears in the eye does not cause obvious visual impairment, then special therapy is usually not prescribed. In general, the treatment tactics are selected taking into account the reasons that provoked the development of pathology. Specialists of the clinic "New Look" offer several ways to solve the diagnosed problem:
- with cataracts and destructive changes in the cornea, surgery is most often recommended;
- with inflammatory processes, special anti-inflammatory drugs in the form of eye drops are prescribed;
- with the formation of connective scar tissue, absorbable preparations are prescribed, for example, Hypromellose, Actovegin, Korneregel.
In this medical center, surgical correction is performed on professional modern equipment. Today, operations are quite affordable and have a short rehabilitation period, which is very convenient.
So do not try to treat your eyes with all kinds of alternative means, as well as a variety of drops without an established diagnosis. Before starting treatment, you should consult an ophthalmologist.
Prevention
The main measure to prevent the appearance of white dots in the eyes is to strengthen the retinal tissues in general. To do this, you should systematically take multivitamin complexes, maintain a healthy lifestyle and visit an ophthalmologist every year for a routine examination. It is especially important to comply with these rules for those with a history of chronic eye pathologies.
In fact, the health of the visual organs is often in the hands of the patient himself. If the pathology has already appeared, then do not delay the visit to the doctor - only he can conduct the necessary diagnostics and prescribe the appropriate therapy.
