• Symptoms
  • With a cataract, the lens can no longer sharply focus the light onto the retina, this light is scattered and causes the symptoms associated with cataract. (news24.com)
  • Symptoms include life-threatening illnesses such as jaundice, hepatosplenomegaly (enlarged spleen and liver), hypoglycemia, renal tubular dysfunction, muscle hypotonia (decreased tone and muscle strength), sepsis (presence of harmful bacteria and their toxins in tissues), and cataract among others. (wikipedia.org)
  • Although treatment for galactosemic infants is a strict galactose-free diet, endogenous (internal) production of galactose can cause symptoms such as long-term morbidity, presenile development of cataract, renal failure, cirrhosis, and cognitive, neurologic, and female reproductive complications.

  • Causes
  • The mechanism by which galactosemia causes cataract is not well understood, but the topic has been approached by researchers for decades, notably by the ophthalmologists, Jonas S. Friedenwald and Jin H. Kinoshita. (wikipedia.org)
  • This causes cataracts after decades of exposure. (wikipedia.org)
  • phacoemulsification
  • The most common form of cataract surgery today involves a process called phacoemulsification. (medicinenet.com)
  • Day care, high volume, minimally invasive, small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world. (wikipedia.org)
  • Phacoemulsification is the most commonly performed cataract procedure in the developed world. (wikipedia.org)
  • Although it requires a larger incision and the use of stitches, the conventional method may be indicated for patients with very hard cataracts or other situations in which phacoemulsification is problematic. (wikipedia.org)
  • Nepean River
  • The Nepean project consisted of the construction of a weir across the Nepean River to divert of the rivers Cataract, Cordeaux, Avon and Nepean, to the Prospect Reservoir. (wikipedia.org)
  • disease
  • As life span increases in the developed world due to modern technology and new methods of treatment of acute and chronic disease, the incidence of age-related cataracts will continue to increase. (medicinenet.com)
  • Although most pets suffering from cataract are treated with surgery, success depends on the presence of retinal disease and underlying eye conditions. (vetinfo.com)
  • 1937
  • Buzz Holmstrom made a solo trip through Cataract Canyon and Grand Canyon in 1937, eventually ending at the newly constructed Hoover Dam. (wikipedia.org)
  • infants
  • The presence of presenile cataract, noticeable in galactosemic infants as young as a few days old, is highly associated with two distinct types of galactosemia: GALT deficiency and to a greater extent, GALK deficiency. (wikipedia.org)
  • Diseases
  • A basic laboratory evaluation for bilateral cataracts of unknown cause in apparently healthy children includes: - Urine test for reducing substance, galactose 1-phosphate uridyltransferase, galactokinase, amino acids - Infectious diseases: TORCH and varicella titers, VDRL - Serum calcium, phosphorus, glucose and ferritin In general, the younger the child, the greater the urgency in removing the cataract, because of the risk of amblyopia. (wikipedia.org)
  • surgery
  • As a full eye care specialists in Baltimore MD. As a top notch cataract dr baltimore we have years of cataract surgery experience. (metacafe.com)
  • Dropless prophylaxis in patients scheduled to undergo cataract surgery seems to be more practical than and as efficacious as the standard of care for use in this patient population. (modernmedicine.com)
  • Do we absolutely need this technology to perform cataract surgery? (modernmedicine.com)
  • Cataract surgery in patients with coexisting uveitis is more challenging than managing either condition alone. (modernmedicine.com)
  • Surgery is needed only if the cataracts are causing problems and generally results in an improved quality of life. (wikipedia.org)
  • Cataract surgery is not readily available in many countries, which is especially true for women, those living in rural areas, and those who do not know how to read. (wikipedia.org)
  • ECCE utilises a larger incision (10-12mm) and therefore usually requires stitching, and this in part led to the modification of ECCE known as manual small incision cataract surgery (MSICS). (wikipedia.org)
  • Manual small incision cataract surgery (MSICS): This technique is an evolution of ECCE (see below) where the entire lens is expressed out of the eye through a self-sealing scleral tunnel wound. (wikipedia.org)
  • cause
  • These cataracts can exist in isolation or in any combination with each other, and each can cause a wide spectrum of vision problems, from unnoticeable to blinding. (britannica.com)
  • Nuclear cataracts cause a slow, progressive yellowing or browning of the central core of the lens as it undergoes compression and hardening. (britannica.com)
  • Cataracts do not cause the eye to tear abnormally. (medicinenet.com)
  • Ultraviolet light, specifically UVB, has been shown to cause cataracts, and some evidence indicates sunglasses worn at an early age can slow its development in later life. (wikipedia.org)
  • Microwave radiation has also been found to cause cataracts. (wikipedia.org)
  • It is known that different mutations in the same gene can cause similar cataract patterns, while the highly variable morphologies of cataracts within some families suggest that the same mutation in a single gene can lead to different phenotypes. (wikipedia.org)
  • 1999
  • The dam and its associated buildings were listed on the New South Wales State Heritage Register on 18 November 1999 with the following statement of significance: Cataract Dam was the first of the four water supply dams built as part of the development of the Upper Nepean Water Supply Scheme, one of the most important engineering works and items of public infrastructure in Australia. (wikipedia.org)
  • flows
  • A cataract bog is a rare ecological community formed where a permanent stream flows over a granite outcropping. (wikipedia.org)
  • The rapids of Cataract Canyon become difficult at flows above 30,000 cu ft/s (850 m3/s) and extreme at flows above 50,000 cu ft/s (1,400 m3/s). (wikipedia.org)
  • development
  • With the development of cataracts, the affected lens becomes like frosted glass.It is no longer clear and therefore difficult to see through. (news24.com)
  • One of the heartbreaks that happen as animals age is the development of cataracts. (dogster.com)
  • The completion of Cataract Dam was a significant step in the continuing process of providing a reliable water supply for Sydney and surrounding areas and was part of a process of development of the Upper Nepean Scheme which was envisaged when that Scheme was designed in the 1880s. (wikipedia.org)
  • found
  • The prevalence of cataract among classic galactosemics is markedly less than among galactokinase-deficient patients due to the extremely high levels of galactitol found in the latter. (wikipedia.org)
  • Other plants found in cataract bogs are limeseep grass-of-Parnassus (Parnassia grandifolia), Indian paint brush (Castilleja coccinea), stiff cowbane (Oxypolis rigidior), Appalachian bluet (Houstonia serpyllifolia) and northern sundrops (Oenothera tetragona). (wikipedia.org)
