Eye cataract comes from the Greek Katarrhakies, England Cataract, and Latin Cataracta which means waterfall. Known as cataract, where vision such as waterfalls closed due to the cloudy lens. Cataracts are any circumstances in lens turbidity that can occur due to hydration (adding liquid) lenses, lens protein denaturation.
Usually the turbidity of both eyes and walked progressive or may not experience a change in a long time.
Eye cataract is generally a disease in the elderly, but can also be caused by congenital abnormalities, or chronic complications local eye disease. Various performance is eye cataracts resulted such as glaucoma, ablation, uveitis, and retinitis pigmentosa. Cataract can be associated with other intraocular disease processes. Cataracts can also be caused by specific toxic materials (chemical and physical). Poisoning several types of diseases can also cause cataracts; like eserin (0,25-0,5%), corticosteroids, ergot, and antikolinesterase topical.
Systemic or metabolic disorders that can cause cataracts are diabetes mellitus, galactosemia, and miotonik dystrophy.
Cataracts can be found in a state without any eye or systemic abnormalities (senile cataracts, juvenile, hereditary) or congenital eye disorders.
Cataracts can be caused by various factors:
* Physical
* Chemistry
* Disease prdisposisi
* Genetic and developmental disorders
* Viral infection fetal growth in the days
* Age
In patients with cataracts usually complain of vision such as smoky and sharp eyesight progressively decreased. This lens turbidity resulting lenses are not transparent, so that pupils will be white or gray.
In the eye lens turbidity will appear in various forms and levels. Turbidity can also be found on a variety of lenses such as localization in the cortex and the nucleus.
Audit performed in patients with cataract is a gap-ray examinations (slitlamp), funduskopi, in both eyes when possible, Schiotz ther than the necessary checks such as an infection in the eyelid, conjunctiva, because it can be severe complications such as post-surgical and panoftalmitis general physical.
In cataract sharp vision examination should be performed before surgery to see if the turbidity is proportional to the sharp decline in eyesight. In thin nuclear cataract with high myopia will look sharp vision that does not fit, so it may come down due to abnormalities of vision in retinal surgery and if done it will give sharper results pengllihatan unsatisfactory. In contrast to the small posterior cortical cataract will lead to a sharp decline in vision that is very heavy on the medium or hard lighting if the patient is a dark place so sharp vision will show much progress.
Treatment of cataracts is surgery. After surgery the lens is replaced with afakia glasses contact lenses.cor intraocular lenses planting.
Cataract classification
Based on age, cataracts are classified into:
* Congenital cataract, cataracts that have been seen at ages under 1 year
* Juvenile cataract, cataract that occurred after age 1 year
* Senile cataract, cataract that occurred after the age of 50 years
When the eye healthy and there is no systemic disorder then this is normally the case in almost all cataract seniliis, hereditary cataracts and congenital.
Congenital cataracts
Congenital cataracts is a starting place before or shortly after birth and gain less than 1 year old. Congenital cataracts cause blindness in infants significantly mainly due to the lack of proper handling.
Congenital cataract in the cataract:
* Kapsulolentikuler where in this class, including cataract and cataract kapsular Polaris.
* Cataract lentikular included in this group the cortex and the nucleus of the lens alone.
In this category including lens turbidity that arises as a primary event or associated with maternal and fetal disease local or general.
To find the cause of congenital cataracts it is important to check such as maternal history of prenatal infection of rubella in the first trimester of pregnancy and drug using during pregnancy. Sometimes pregnant women have a history of seizures, tetani, jaundice or hepatosplenomegaly. If the cataract is accompanied by reduction in urine test positive, cataracts may occur due to galactosemia. Congenital cataracts are often found in premature babies and nervous system disorders such as mental retardation.
Blood tests on congenital cataract needs to be done because there hubungna congenital cataracts with diabetes mellitus, calcium and phosphorus. Almost 50% of congenital cataracts are sporadic and no known cause.
Handling depends on the unilateral and bilateral, other eye abnormalities, and cataracts as they arise. Congenital cataracts prognosis is less satisfactory because it depends on the form of cataracts and may well have occurred in the eye ambliopia. When tredpat nistagmus then this situation indicates a bad thing in congenital cataracts.
In the eye cataract can kongnital known several forms:
* Cataract piramidalis or anterior Polaris
* Cataract piramidalis or posterior Polaris
* Cataract zonularis or lamalaris
* Cataract pungtata and others.
In the infant pupils who suffer from congenital cataracts visible white spots or leukokoria. At each leukokoria required a more thorough examination to rule out other differential diagnosis. Leukokoria examination conducted by pupils dilate.
In total congenital cataract complication that can happen is the macula lutea is not getting enough stimulation. Macula is not fully developed cataract extraction although the visusnya usually will not reach 5 / 5. This is called sensory ambliopia (ex ambyopia anopsia). Congenital cataracts can cause other complications such as nistagmus and strabismus.
Congenital cataracts are often found in babies born to mothers who suffer from rubella, galactosemia, homosisteinuria, inclusion sitomegalik, diabetes mellitus, hipoparatiroidism, toxoplasmosis, and histoplasmosis. Other diseases that accompany congenital cataract is usually a hereditary disease like mikroftalmus, aniridia, iris Coloboma, karatoknus, sliced heterokromia, ectopic lens, retinal dysplasia, and megalo cornea.
Turbidity in congenital cataracts can be found in various forms and morphological description.
