Lens Capsule, Crystalline: The thin noncellular outer covering of the CRYSTALLINE LENS composed mainly of COLLAGEN TYPE IV and GLYCOSAMINOGLYCANS. It is secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears.Anterior Capsule of the Lens: The anterior aspect of the casing that surrounds the natural CRYSTALLINE LENS.Capsulorhexis: The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (Dorland, 28th ed)Lens DiseasesLenses, Intraocular: Artificial implanted lenses.Joint Capsule: The sac enclosing a joint. It is composed of an outer fibrous articular capsule and an inner SYNOVIAL MEMBRANE.Cataract: Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)Cataract Extraction: The removal of a cataractous CRYSTALLINE LENS from the eye.Lens Implantation, Intraocular: Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.Capsules: Hard or soft soluble containers used for the oral administration of medicine.Acrylic ResinsLens, Crystalline: A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.Phacoemulsification: A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1)Polymethyl Methacrylate: Polymerized methyl methacrylate monomers which are used as sheets, moulding, extrusion powders, surface coating resins, emulsion polymers, fibers, inks, and films (From International Labor Organization, 1983). This material is also used in tooth implants, bone cements, and hard corneal contact lenses.Laser Therapy: The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.Lenses: Pieces of glass or other transparent materials used for magnification or increased visual acuity.Contact Lenses: Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999)Bacterial Capsules: An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.Capsule Endoscopy: Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.Contact Lenses, Hydrophilic: Soft, supple contact lenses made of plastic polymers which interact readily with water molecules. Many types are available, including continuous and extended-wear versions, which are gas-permeable and easily sterilized.Lens Cortex, Crystalline: The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.Capsule Endoscopes: A pill sized videocamera encased in a capsule. It is designed to be swallowed and subsequently traverse the gastrointestinal tract while transmitting diagnostic images along the way.Lens Nucleus, Crystalline: The core of the crystalline lens, surrounded by the cortex.Crystallins: A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.Internal Capsule: WHITE MATTER pathway, flanked by nuclear masses, consisting of both afferent and efferent fibers projecting between the WHITE MATTER and the BRAINSTEM. It consists of three distinct parts: an anterior limb, posterior limb, and genu.Contact Lenses, Extended-Wear: Hydrophilic contact lenses worn for an extended period or permanently.Lens Subluxation: Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.Contact Lens Solutions: Sterile solutions used to clean and disinfect contact lenses.Posterior Capsule of the Lens: The posterior aspect of the casing that surrounds the natural CRYSTALLINE LENS.Presbyopia: The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation.Fungal Capsules: An extracellular layer outside the cell wall of a fungus composed of polysaccharides. It may serve a protective role amongst others.Bowman Capsule: A double-walled epithelial capsule that is the bulbous closed proximal end of the kidney tubular system. It surrounds the cluster of convoluted capillaries of KIDNEY GLOMERULUS and is continuous with the convoluted PROXIMAL KIDNEY TUBULE.Accommodation, Ocular: The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances. (Cline et al., Dictionary of Visual Science, 4th ed)Subrenal Capsule Assay: In vivo method of screening investigative anticancer drugs and biologic response modifiers for individual cancer patients. Fresh tumor tissue is implanted under the kidney capsule of immunocompetent mice or rats; gross and histological assessments follow several days after tumor treatment in situ.Capsule Opacification: Clouding or loss of transparency of the posterior lens capsule, usually following CATARACT extraction.Refraction, Ocular: Refraction of LIGHT effected by the media of the EYE.Eye ProteinsSilicones: A broad family of synthetic organosiloxane polymers containing a repeating silicon-oxygen backbone with organic side groups attached via carbon-silicon bonds. Depending on their structure, they are classified as liquids, gels, and elastomers. (From Merck Index, 12th ed)Eye: The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.beta-Crystallins: A class of crystallins that provides refractive power and translucency to the lens (LENS, CRYSTALLINE) in VERTEBRATES. Beta-crystallins are similar in structure to GAMMA-CRYSTALLINS in that they both contain Greek key motifs. Beta-crystallins exist as oligomers formed from acidic (BETA-CRYSTALLIN A CHAIN) and basic (BETA-CRYSTALLIN B CHAIN) subunits.Polysaccharides, Bacterial: Polysaccharides found in bacteria and in capsules thereof.Aphakia: Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.Eyeglasses: A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.alpha-Crystallins: A subclass of crystallins that provides the majority of refractive power and translucency to the lens (LENS, CRYSTALLINE) in VERTEBRATES. Alpha-crystallins also act as molecular chaperones that bind to denatured proteins, keep them in solution and thereby maintain the translucency of the lens. The proteins exist as large oligomers that are formed from ALPHA-CRYSTALLIN A CHAIN and ALPHA-CRYSTALLIN B CHAIN subunits.Epithelial Cells: Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

Quantitative analysis of SOD2, ALDH1A1 and MGST1 messenger ribonucleic acid in anterior lens epithelium of patients with pseudoexfoliation syndrome. (3/3)PURPOSE: The aim of the study was to investigate the expression of selected genes encoding enzymes involved in the antioxidant defense system (superoxide dismutase 2, SOD2; aldehyde dehydrogenase 1, ALDH1A1; microsomal glutathione S-transferase 1, MGST1) in fragments of anterior lens capsules of patients with pseudoexfoliation syndrome (PEX). The specificity and sensitivity of these molecular markers for PEX development were also assessed. METHODS: The study group consisted of 20 patients (9 women and 11 men) with diagnosed PEX and cataract. The control group included 23 patients (8 women and 15 men) who needed cataract surgery but did not have PEX. Quantification of SOD2, ALDH1A1, and MGST1 messenger ribonucleic acid (mRNA) was performed with quantitative real-time PCR. RESULTS: SOD2, ALDH1A1, and MGST1 mRNAs were detected in all studied samples. The examined genes had statistically significant higher expression in the group of patients with PEX than in the control group (SOD2, p=0.0015; ALDH1A1, p=0.0001; MGST1, p=0.0001, Mann-Whitney U test). The areas under the curve (AUC) of SOD2, MGST1, and ALDH1A1 were 0.766, 0.818, and 0.957, respectively. CONCLUSIONS: Differential expression of SOD2, ALDH1A1, and MGST1 genes in the anterior lens capsules of patients with PEX suggest that diseased tissue appears to respond to the previously reported oxidative stress. A possible role of ALDH1A1 mRNA level as a risk factor or marker for PEX needs further confirmation. (+info)

To determine exon-intron structures and genomic organization, the human and (rhesus) macaque genomes were analyzed using BLAT. The first exon (noncoding) of macaque MGST3 was predicted from the human MGST3 sequence because the identified cynomolgus/rhesus MGST cDNAs contained only the coding sequence. Among the macaque MGST sequences analyzed, the largest was MGST2 (,37 kilobases), followed by MGST3 and MGST1, similar to human sequences (Supplemental Fig. 1). Macaque MGST1, MGST2, and MGST3 contained 4, 5, and 6 exons, respectively, similar to humans (Supplemental Fig. 1). Other than the first and last exons, whose sizes vary due to inclusion of noncoding sequences, the sizes of the MGST1, MGST2, and MGST3 exons were the same in macaques and humans, ranging from 58 base pairs (bp) to 124 bp, except for exon 2 of MGST1 (158 bp in macaques and 148 bp in humans). This discrepancy might be attributable to the use of a splice acceptor site (AG) in macaque MGST1, 10 bp upstream of that of human MGST1. ...

Model of Plasma Characteristics across the Anterior Lens and Aqueous Boundary | IOVS | ARVO Journals
Purpose: The purpose of this study was to investigate the expected laser plasma characteristics across the anterior lens and aqueous boundaries.. Methods: A laser plasma model was developed that describes the evolution of plasma developed from focusing a short pulse laser. This model included plasma shielding characteristics in the description of the plasma evolution. The model characteristics in water where compared the moving breakdown model to validate performance. The model was then applied to the anterior boundary between the lens and the anterior chamber where the characteristics of the boundary was described by using an energy level model to represent the different constituents of the boundary. The aqueous, capsule, and fibrous mass were modeled having a binding energy of 6.5eV, 7.5eV, and 6.8eV respectively. The focal position of the laser pulse in an F/4 system relative to the boundary was then analyzed to determine the characteristics of the laser interaction across the boundary. The ...

Pseudoexfoliation syndrome is an age-related systemic disease that mainly affects the anterior structures of the eye. Despite a worldwide distribution, reported incidence and prevalence of this syndrome vary widely between ethnicities and geographical areas. The exfoliative material is composed mainly of abnormal cross-linked fibrils that accumulate progressively in some organs such as the heart, blood vessels, lungs or meninges, and particularly in the anterior structures of the eye. The exact pathophysiological process still remains unclear but the association of genetic and environmental factors are thought to play a role in the development and progressive extracellular accumulation of exfoliative material ...

An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a layer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.
Pseudoexfoliation syndrome, often abbreviated as PEX and sometimes as PES or PXS, is an aging-related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. Its cause is unknown, although there is speculation that there may be a genetic basis. It is more prevalent in women than men, and in persons past the age of seventy. Its prevalence in different human populations varies; for example, it is prevalent in Scandinavia. The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision (pseudoexfoliation glaucoma, exfoliation glaucoma). As worldwide populations become older because of shifts in demography, PEX may become a matter of greater concern. Patients may have no specific symptoms. In some cases, patients may complain of lessened visual acuity or changes in their perceived ...
The patient presents with a fine, flaky material on the anterior lens capsule at the pupillary margin. Over time, this coalesces into a characteristic "bulls-eye" pattern seen in pseudoexfoliation. There is often increased transillumination of the iris at the pupillary margin and there may be pigment granules on the endothelium and iris surface. Within the angle, there may be observable pigment or clear flaky material. Initially, intraocular pressure is unaffected; however, elevated IOP develops in up to 80 percent of patients. In these cases, glaucomatous cupping and visual field loss may ensue ...

Cataract surgery in patients with pseudoexfoliation syndrome: current updates Luigi Fontana, Marco Coassin, Alfonso Iovieno, Antonio Moramarco, Luca Cimino Ophthalmology Unit, Arcispedale Santa Maria Nuova – IRCCS, Reggio Emilia, Italy Abstract: Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc.), the risk of intraoperative complications may be much reduced, allowing
Aging | Laminin α4 overexpression in the anterior lens capsule may contribute to the senescence of human lens epithelial cells...
Senescence is a leading cause of age-related cataract (ARC). The current study indicated that the senescence-associated protein, p53, total laminin (LM), LMα4, and transforming growth factor-beta1 (TGF-β1) in the cataractous anterior lens capsules (ALCs) increase with the grades of ARC. In cataractous ALCs, patient age, total LM, LMα4, TGF-β1, were all positively correlated with p53. In lens epithelial cell (HLE B-3) senescence models, matrix metalloproteinase-9 (MMP-9) alleviated senescence by decreasing the expression of total LM and LMα4; TGF-β1 induced senescence by increasing the expression of total LM and LMα4. Furthermore, MMP-9 silencing increased p-p38 and LMα4 expression; anti-LMα4 globular domain antibody alleviated senescence by decreasing the expression of p-p38 and LMα4; pharmacological inhibition of p38 MAPK signaling alleviated senescence by decreasing the expression of LMα4. Finally, in cataractous ALCs, positive correlations were found between LMα4 and total LM, as well as
