Lens opacity and photoreceptor degeneration in the zebrafish lens opaque mutant.

Belépés Regisztrálás
The zebrafish lens opaque (lop) mutant was identified in a chemical mutagenesis screen. The lop mutant, which develops normally through 4 days postfertilization (dpf), exhibits several signs of lens and retinal degeneration at 7 dpf. Histology revealed disrupted lens fibers and increased numbers of
Refractive lens exchange with a multifocal intraocular lens.

Refractive lens exchange with a multifocal intraocular lens is becoming a more popular method of refractive surgery in the presbyopic patient. The limitations of keratorefractive surgery have led to a resurgence of lens exchange surgery for patients with prescriptions outside the limits of corneal
Teleost lens development and degeneration.

The transparent properties of the lens and its ability to focus light onto the retina are critical for normal vision. Optical clarity of the lens is achieved and maintained by a unique, highly regulated integration of lens cell proliferation and differentiation that persists throughout life.

OBJECTIVE
The purpose of this study is to review and evaluate the advantages and disadvantages of blue light (400-480 nm) filtering intraocular lenses (IOLs) when compared with the ultraviolet (UV)-blocking IOLs.
RESULTS
Theories that blue light could be related to the pathogenesis of age-related
Calcified cataractous lens.

We report a calcified cataractous lens in a 24-year-old man who had retinal degeneration in the right eye since childhood. The visual acuity had dropped to light perception. Clear corneal phacoemulsification was performed, and the shell of a 5.4 mm x 4.0 mm x 2.0 mm calcified substance was removed
Snowflake degeneration of an intraocular lens.

Snowflake degeneration of intraocular lenses is a recently recognized late postoperative complication of cataract surgery. All known cases reported to date in the literature have involved polymethyl methacrylate (PMMA) lens optic material. Reported herein is an atypical variant of snowflake

The lens in the dyl mutant mice shows a persistent lens-ectodermal connection as well as degeneration and extrusion of lens materials after the initial differentiation of the fibres. Immunohistochemical investigation of the ontogeny of the lens crystallins in this developing mutant lens has been
An intraocular telescopic lens for macular degeneration.

Age-related macular degeneration is a leading cause of visual loss in adults older than 60 years of age. Once vision has been seriously compromised, the only means of improving visual function are optical devices that produce magnification of images. These devices fall into three categories: (1)
Bilateral intraocular lens implantation.

A study of 1796 consecutive cataract patients in a posterior chamber intraocular lens implant (IOL) series revealed 373 patients (20.8%) who had bilateral IOLs. Visual acuity was 20/40 or better in 87% of first eyes operated and 90% in second eyes. The major cause of vision less than 20/40 was

OBJECTIVE
To review the current status of phakic intraocular lenses (IOLs), intraocular treatment of presbyopia, and IOLs that filter some blue light.
METHODS
Review of current information on the subject from numerous sources.

A patient with Terrien's corneal marginal degeneration and a previous trabeculectomy had planned extracapsular cataract extraction with intraocular lens implantation. A corneal incision was made with a diamond blade on the degeneration furrow superiorly and was closed with a 10-0 nylon
Disposable contact lens wear systems.

The majority of problems associated with soft lens wear in general are related to lens deterioration, deposits, care systems, and lack of patient compliance. The greatest problem with soft lenses is that they can never be totally cleaned. The point of a disposable lens wear program is to discard the

The etiopathogenesis of iridoschisis is unclear, although age-related degeneration and angle-closure glaucoma are its most common associations. We report the case of a 50-year-old man with lens subluxation (familial) in 1 eye and ipsilateral iridoschisis. The inferotemporal edge of the lens was
