Immature Cataract

Presentation

These symptoms do not necessarily indicate cataract, but if any of them are present, an ophthalmologist should be consulted immediately. Treatment. [medical-dictionary.thefreedictionary.com]

Signs and symptoms A patient with senile cataract often presents with a history of gradual progressive visual deterioration and disturbance in night and near vision. [emedicine.medscape.com]

Blue-light filtering IOLs[edit] Blue light filtering IOLs filter the UV and high-energy blue light present in natural and artificial light, both of which can cause vision problems;[citation needed] however too much filtering of blue light can increase [en.wikipedia.org]

Eyes

  • Marcus-Gunn Pupil

    Gunn pupil or a relative afferent pupillary defect (RAPD) indicative of optic nerve lesions or severe diffuse retinal involvement Slit lamp examination - Should concentrate on the evaluation of not only lens opacity but also other ocular structures [emedicine.medscape.com]

  • Prolapse

    Some of these complications include anterior capsular radial tears, which in turn may destabilize the capsular bag leading to difficulty in removing cortical lens material, posterior capsular tears, vitreous prolapse and IOL instability [10]. [eyewiki.aao.org]

Treatment

Treatment. The only known effective treatment for cataract is surgical removal of the lens (lens extraction or cataract extraction). The procedure of choice was formerly intracapsular extraction, with total removal of the lens within its capsule. [medical-dictionary.thefreedictionary.com]

Risk Factors Risk factors include excessive alcohol consumption, tobacco, UV exposure, chronic steroid use, previous radiation treatment, thalassemia, previous chemotherapy [4]. [eyewiki.aao.org]

Management Lens extraction is the definitive treatment for senile cataract. [emedicine.medscape.com]

Intraocular lens A posterior chamber IOL (with haptics) ICD-9-CM 13.72 MeSH D054120 OPS-301 code 5-984 [edit on Wikidata] Intraocular lens (IOL) is a lens implanted in the eye as part of a treatment for cataracts or myopia. [en.wikipedia.org]

Dr. de Schweinitz, referring to the medicinal treatment of cataract, stated that no drugs were known which could dissipate lenticular opacities. [jamanetwork.com]

Prognosis

[…] a very promising visual prognosis of gaining at least 2 lines in the Snellen distance vision chart. [emedicine.medscape.com]

Etiology

Etiologies There are numerous factors that may lead to the formation of an intumescent cataract. [eyewiki.aao.org]

Diagnosis can also include the following: Examination of the ocular adnexa and intraocular structures - May provide clues to the patient's cataract etiology, concomitant disease, and eventual visual prognosis Swinging flashlight test - Detects a Marcus [emedicine.medscape.com]

Epidemiology

Cataracts as an epidemiologic problem. Am J Ophthalmol. 1977 Mar. 83(3):334-9. [QxMD MEDLINE Link]. Sommer A, Tielsch JM, Katz J, Quigley HA, Gottsch JD, Javitt JC, et al. [emedicine.medscape.com]

Epidemiology Cataract severity ranges from incipient, immature, intumescent, mature corticonuclear, hypermature Morganian, and finally shrunken Morganian. [eyewiki.aao.org]

Pathophysiology

Pathophysiology On slit-lamp exam, the first sign of intumescent cataracts is vacuole and cortical spoke formation. [eyewiki.aao.org]

Pathophysiology The pathophysiology behind senile cataracts is complex and yet to be fully understood. [emedicine.medscape.com]

Prevention

Simultaneously, these epithelial cells are forming new layers of cells on top of damaged layers in order to prevent gap formation[4]. [eyewiki.aao.org]

Prevent Blindness America currently estimates that more than 22 million Americans aged 40 years and older have a cataract. [emedicine.medscape.com]
