Aphakia is a pathological condition of the organ of vision, which is characterized by the absence of a lens in the eyeball. Clinically, the disease is manifested by a decrease in visual acuity, trembling of the iris, loss of the ability to accommodate and asthenopic complaints. Diagnosis of aphakia includes visometry, gonioscopy, biomicroscopy, ophthalmoscopy, refractometry…
Optic atrophy (optical neuropathy) is a partial or complete destruction of nerve fibers that transmit visual stimuli from the retina to the brain. Atrophy of the optic nerve leads to a decrease or complete loss of vision, narrowing of the visual fields, impaired color vision, paleness of OND. The diagnosis is made when identifying characteristic…
Eyeball atrophy is a condition in which the eyeball is deformed and reduced in size with a significant decrease in visual functions. The main causes of the development of atrophy of the eye are severe injuries of the visual organ, prolonged inflammation, retinal detachment. Symptomatically, atrophy of the eyeball is manifested by a lack of…
Astigmatism is a violation of refraction caused by an irregular, non-spherical shape of the cornea or lens, which leads to the scattering of light rays and the formation of a distorted image on the retina. Disease over 1 dpt is manifested by visual impairment, blurry blurry vision of objects, headache, rapid fatigue with visual loads,…
Asthenopia is a functional visual disorder that is accompanied by increased fatigue when performing visual work. It is clinically manifested by a burning sensation, pain, hyperemia, the appearance of fog in front of the eyes, a feeling of sand, as well as a decrease in visual acuity that develop after intense or prolonged visual work.…
Everyone knows that a sedentary lifestyle is not the most useful for maintaining good health. But in what cases can a person be called sedentary, by what criteria to check whether he leads a “sedentary” life and how serious is the danger of inactivity for cardiac activity? Let’s look into these issues together. What is…
Anophthalmos is an ophthalmopathology characterized by the absence of an eyeball in the orbit. Clinical manifestations of the disease are irreversible loss of visual functions on the side of the lesion, narrowing of the boundaries of the visual field, violation of spatial perception and rapid fatigue when performing visual work with a healthy eye. Diagnostics…
Color vision abnormalities are a complex of pathologies of congenital or acquired genesis, including achromatopsia, color blindness and acquired color vision deficiency. Clinical symptoms are represented by impaired color perception, decreased visual acuity, and nystagmus. Electroretinography, anomaloscopy, Rabkin tables, Ishihara test and FALANT are used to diagnose color vision anomalies. The main principle of treatment…
Lens anomalies are malformations, less often acquired pathologies in which the ability to accommodate, light transmission or light refraction is impaired. Common symptoms for most forms are impaired visual functions, the appearance of “fog” or “shroud” in front of the eyes. Diagnostics includes external examination, biomicroscopy, gonioscopy, visometry, ultrasound in In-mode, OCT. Treatment tactics depend…
Refractive errors are a group of diseases in ophthalmology in which a decrease in visual acuity is caused by a violation of the focus of the image on the retina. Common symptoms for all pathologies: blurred vision, rapid eye fatigue when performing visual work, discomfort or headache with eye strain. Visometry, refractometry, ophthalmoscopy, eye ultrasound,…
