the Cataract ( the cataracta) then the relating the crystalline lens of eye disease. Depends on partial or total her turbidity, which inflicts, that crystalline lens loses his the most essential optical feature, tzn. transparency.
the connected with age Cataract, tzw. " the cataract is enough” this one of the most frequent wholesome problems in ophthalmology.
connected with age Cataract (tzw. "cataract is enough”) it concerns in equal degree both sexes, her beginnings can step out after 40 year of life, and it comes out with rule about 50 – 60 r. ż. Disease this causes from sometimes the loss of sight. The cataract is on world the main cause of blindness. This is however the of sight reversible loss. At dorosłych, in case of cataract connected with age it moves away the become turbid crystalline lens operacyjnie, and it in this place grafts the artificial crystalline lens and the chory regains the sight. The treatment conducts oneself in case of inborn cataract at children differently.
connected with age cataract the most Often be happened (tzw. "cataract is enough”) – this is over 90% cases of cataract. Inborn cataract is next kind – it concerns children. Toxic cataract be favoured also - this the most often cataract posteroidowa (turbidity crystalline lens appears in course treatment steroidami). To to come into being cataract it can in course such diseases how np. diabetes, it is this tzw. metabolic cataract. To to come into being tężyczkowa cataract it can in course of spontaneous tetany at children, at dorosłych przytarczyc can step out after removal. Tzw. is the next kind the entangling cataract - secondary in relation to different diseases of eye, the most often caused by disease about inflammable character. The injury, tzw. can with cause of cataract be also the posttraumatic cataract - the influence of temperature ( the infra-red radiation), the paralysis the electric current the, radiation, of injury the penetrating optic knobs, strange wewnątrzgałkowe bodies.
connected from lid with Symptoms of cataract, that is tzw. of senile cataract can the sight, deformation of painting, problems be foggy with acuteness of sight in bright light or the leadership of car in night (blinding), the falls or the incidents, injuries (np. the fracture of neck of femoral os) as after-effect of deterioration of sight, in medical investigation the visible turbidity of crystalline lens.
In connected with age cataract, that is in senile cataract continuous, by whole life formation the next layers of fibres of crystalline lens brings to hard rise, the drained testicle of the crystalline lens which enfeebles sight. The aging the organism causes the change of biochemical equilibrium also and osmotic required to maintenance of transparency of crystalline lens. External layers enlarge hydration and they become opaque, reducing the acuteness of sight.
At dorosłych from undertaking decision about treatment operating was not one should wait till moment total the turbidity of crystalline lens. It undertakes her wówczas usually, when sight worsens to this degree, that this normal life makes difficult patient. Because it to development of advanced cataract comes gradually, the patient can be not conscious, she in what degree influenced on change his mode of life ( the patient gets used to gradually and the slowly pogarszać quality of sight).
the Majority the technician operating the grafting the artificial crystalline lens hugs immediately after removal the cataract ( the become turbid crystalline lens of eye). After removal cataract prognosis which to sight is good. At present applied operating methods pozwalać on quick surgical achievement of good function of eye.
In early stage of disease in case of cataract connected with age, in aim it complies the the preventive treatment the progress of turbidity of crystalline lens the preparations in figure of drop to eyes which working has on aim the improvement of lenticular metabolism often (np. in Poland the preparations the Catalin, Vitreolent). Their effectiveness is difficult to proof, because the speed of development of cataract is severally different.
inborn cataract requires at children Separate discussion.
the present turbidity in crystalline lens can be at children with Symptoms of inborn cataract already near birth or in first months of life, often asymptomatic or noticed by parents the child's visual inattention be the squint ( the lazy eye). White reflex from pupil, white pupil - is display this basic. This symptom steps out however also near retinoblastoma it - is then wewnątrzgałkowy bump. Baby can press eyes thumbs or piąstkami ( bilateral cataract). Different symptoms then the squint, nystagmus as well as the incorrect result of investigation of acuteness sight in one or both eyes.
At children near this type symptoms was one should always exclude the presence of wewnątrzgałkowego bump - early diagnosis and treatment retinoblastoma can save life.
Similar how in cataract symptoms can also accompany different diseases and they require proper medical diagnosis always as well as suitable to cause healing conduct.
it usually In taken cause cataract is unknown. The influence of medicines be taken under attention (np. applying the kortykosteroidów in first term of cyesis, the sulphamide). To be connected with diabetes at mother maybe, the galaktozemią of foetus, contagion the wewnątrzmacicznym in first term of cyesis ( the German measles, contagion the virus of cold sore, mumps) as well as the undernutrition the wewnątrzmacicznym.
In case of inborn cataract the total bilateral cataract should be removed in first months of life surgically, to does not allow to deep rise and the durable shortsighness, and make possible the child's correc psychical development also. After operation it necessary is the immediate correction of the insufficient refraction which in the simplest way can glasses be compensated. The implants of wewnątrzgałkowych crystalline lenss ( the artificial crystalline lens) they do not be apply at children poniżej second year of life.
One-sided cataract is relative indication to operation and she be removed in period, it when was can assure optical correction formed after operation bezsoczewkowości. Contact crystalline lenss one-sided bezsoczewkowość be compensated.
child's Rehabilitation requires long-lasting the treatment of shortsighness formed in result of one-sided cataract and it joins with necessity of long-wave surgical care. The co-operation of parents with doctor (manyyears') it, complying to his recommendations, is the basic condition of achievement of therapeutic result.
the Sight is one of these senses which has on man's life the largest influence. Almost 90% of all sensorial experiences then the visual experiences. From here so important the health of eyes is. The connected with age cataract is one of these diseases which can be treated effectively, then the the most frequent oculistic illness, causing tzw. the reversible blindness. Similar to cataract the caused symptoms can be however by many different diseases of organ of sight, or else the central nervous arrangement. They require always medical diagnosis.
In case of wholesome problems and was one should turn after advice to doctor any doubts. Only medical leaning on personal examining patient, interview with sick leave advice and conduct guarantees additional investigations always safe, such, which can give desirable wholesome effect. Above mentioned article gives only general knowledge about problem, what it is cataract. Here introduced data have only informative value and they can not replace professional medical advice.
