SiRNA targeting EGFR effectively prevents posterior capsular opacification after cataract surgery. (3/20)

PURPOSE: We investigated the effect of epidermal growth factor receptor (EGFR) siRNA on human lens epithelium (HLE) cells and the development of posterior capsular opacity (PCO). METHODS: We designed EGFR siRNA and used it to knockdown the expression of EGFR in HLE cells. Cell proliferation was examined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), cell growth curve assay and cell cycle analysis. Next, we selected an adaptable concentration of recombinant epidermal growth factor (EGF) for stimulating the growth of HLE cells to further test the suppressive effect of siRNA. At last, we established the model of PCO in rats to further investigate whether knocking down EGFR would prevent the progression of PCO in vivo. RESULTS: The cell proliferation of EGFR siRNA group was apparently inhibited no matter in short or long term and cell cycle was arrested in G(1) phase. Over expression EGF cannot rescue the inhibition of EGFR siRNA on HLE cells and the proliferation activity in HLE cells greatly decreased when EGF-EGFR signal pathway blockaded. In vivo experiments, the extent of PCO of EGFR siRNA group is much lower than the control group. CONCLUSIONS: Our results demonstrate that EGFR siRNA can effectively inhibit the progression of PCO. Thus, siRNA targeting EGFR may provide a totally new way for preventing PCO or even cataract.  (+info)

The impact of capsulorhexis diameter, localization and shape on posterior capsule opacification. (5/20)

BACKGROUND: The aim of this study was to evaluate the impact of capsulorhexis diameter, localization and shape on posterior capsule opacification (PCO) development after cataract extraction with phacoemulsification. MATERIAL/METHODS: We retrospectively analyzed of 297 patients who underwent phacoemulsification and AcrySof SA60AT implantation. In a first group of 97 patients, 53 received small capsulorhexis (3.9 to 4.9 mm in diameter) and 44 patients received large capsulorhexis (5.0 to 5.9 mm in diameter). Another group of 99 patients was split into subgroups--66 patients whose capsulorhexis were centrally located and 33 patients whose capsulorhexis were paracentral. A third group of 101 patients was split into subgroups--a subgroup of 59 patients were classified as having a regularly rimmed capsulorhexis and a subgroup of 42 patients as having an irregularly rimmed capsulorhexis. At 6 months follow-up, PCO was classified as none, mild, moderate, or severe, depending on the number of quadrants involved. RESULTS: 86.79% of the patients with a small capsulorhexis had no or mild PCO (p<0.001), whereas, 68.18% of the patients with a large capsulorhexis experienced moderate or severe PCO; 89.4% of the patients with a central capsulorhexis had no or mild PCO (p<0.001), whereas, 75.75% of the patients with a paracentral capsulorhexis had moderate or severe PCO; 86.44% of the patients with a regularly rimmed anterior capsulorhexis had no or mild PCO (p<0.001); and 69.04% of the patients with an irregular capsulorhexis rim had moderate or severe PCO. CONCLUSIONS: A small capsulorhexis diameter, its central localization and regular shape result in less PCO following phacoemulsification.  (+info)

Zebularine suppresses TGF-beta-induced lens epithelial cell-myofibroblast transdifferentiation by inhibiting MeCP2. (6/20)

PURPOSE: Posterior capsular opacification (PCO) is a common long-term complication of modern cataract surgery. Remnant lens epithelial cells (LECs) undergo a myofibroblast transdifferentiation that is thought to be the initial step of PCO pathogenesis. The purpose of this study is to determine the effects of zebularine on transforming growth factor-beta (TGFbeta)-induced, LEC-myofibroblast transdifferentiation. METHODS: The expression levels of methyl CpG binding protein 2 (MeCP2) and alpha-smooth muscle actin (alpha-SMA) in human PCO membranes were evaluated by confocal microscopy. The role that MeCP2 played in TGFbeta2-induced alpha-SMA expression was analyzed by western blotting both before and after MeCP2 knockdown with MeCP2-specific siRNA. The effect of zebularine on MeCP2 expression was analyzed over time using a variety of dosages. The effect of zebularine on TGFbeta2-induced alpha-SMA expression was determined by western blot analysis. RESULTS: MeCP2 and alpha-SMA co-localized in human PCO membranes. When MeCP2 was depleted, TGFbeta2 could not induce alpha-SMA expression. Zebularine decreased MeCP2 expression in lens epithelial cells in a time- and dose-dependent pattern and reversed TGFbeta2-induced alpha-SMA expression. CONCLUSIONS: MeCP2 plays an important role in TGFbeta2-induced alpha-SMA expression in lens epithelial cells. Zebularine could reverse the TGFbeta2-induced alpha-SMA expression by inhibiting MeCP2 expression. Therefore, zebularine could potentially prevent PCO formation.  (+info)

Posterior capsule opacification (PCO) is a fairly common complication of cataract surgery. Sometimes you can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place.This thickening of the capsule causes your vision to become cloudy. If this happens you may need to have laser treatment to make vision clear again. Once you have had the laser treatment for PCO it doesnt normally cause any long term problem with your sight.

Purpose : Many drugs have been loaded onto IOLs by different methods to achieve a sustained and controlled release of drugs to treat posterior capsular opacification (PCO). This study tested the hypothesis that the sustained release of genistein (GEN) from negative charged nanoparticles surface modified IOL by ester bond can prevent the PCO in rabbit eyes effectively and safely.. Methods : Nanostructured lipid carriers (NLCs) loaded with GEN (GEN-NLC) were made by melt emulsification method. GEN-NLCs were attached on IOLs by ester bond formed by the dehydration between the carboxyl group offered by the sodium deoxycholate on the NLC surface and the hydroxy group of hydrophilic acrylic IOLs. The morphology and release of the GEN-NLC on the surface of IOLs and was measured. Sixty New Zealand albino rabbits undergoing phacoemulsification in left eye were randomly and equally divided into three groups. Group A: original IOL; group B: anterior chamber (AC) injection GEN-NLC and original IOL; group C: ...
Aslam and colleagues6 have presented, in the BJO, a systematic analysis of strategies to evaluate posterior capsule opacity and have pointed out that at present there is no entirely satisfactory method of comprehensively quantifying capsule opacity in vivo. In addition to regional quantitation of the optical density of capsule opacity, typically scored subjectively or by analysis of digitised photographs, capsule opacity has fibrotic and lens epithelial proliferative components that require three dimensional measurement. In order to assess the extent of opacification, researchers such as Sacu and colleagues have resorted to multiple modes of evaluation including a subjective score that ranks subtypes of fibrotic opacity, automated analysis of digitised photographs, and need for Nd:YAG laser capsulotomy.4 Hayashi and Hayashi7 have argued that multiple methods are indeed required to adequately describe these various features, and have suggested that retroillumination photography is helpful in ...
Injury to lens epithelial cells (LECs) leads to epithelial-mesenchymal transition (EMT) with resultant fibrosis. The tropomyosin (Tpm) family of cytoskeleton proteins is involved in regulating and stabilizing actin microfilaments. Aberrant expression of Tpms leads to abnormal morphological changes with disintegration of epithelial integrity. The EMT of LECs has been proposed as a major cause of posterior capsule opacification (PCO) after cataract surgery. Using in vivo rodent PCO and human cataractous LECs, we demonstrated that the aberrant expression of rat Tpm and human Tpm1α/2β suggested their association in remodelling of the actin cytoskeleton during EMT of LECs. Expression analysis from abnormally growing LECs after lens extraction revealed elevated expression of α-smooth muscle actin (α-SMA), a marker for EMT. Importantly, these cells displayed increased expression of Tpm1α/2β following EMT/PCO formation. Expression of Tpm1α/2β was up-regulated in LECs isolated from cataractous ...

Purpose : The goal of this research is to develop polymers to prevent posterior capsule opacification (PCO) by inhibiting adhesion of lens epithelial cells (LECs). PCO is the most common complication of cataract surgery, reported in as many as half of all patients 2-5 years after surgery. Previous studies demonstrate conflicting evidence about the impact of intraocular lens (IOL) hydrophilicity on LEC adhesion. These conflicting reports indicate that there is likely an optimal intermediate surface energy, or that there may be another factor in addition to surface energy that is influencing LEC response. This study seeks to determine both the chemical and mechanical factors that influence LEC adhesion and proliferation. Methods : A series of amphiphilic polymers covering a range of surface energies ranging from very hydrophilic to very hydrophobic were synthesized by free radical copolymerization. The monomers used in designing the amphiphilic polymers have been used previously in ophthalmic ...

Cataracts are a degenerative change of the lens, resulting in an opacity and interference with optical clarity and vision. Cataracts are the most common cause of blindness in dogs. Surgical removal of the cataract and replacement with an artificial intraocular lens implant (IOL) restores vision. The leading complication of cataract surgery in dogs and humans is posterior capsular opacification (PCO), a hazy opacity of the lens capsule developing post-operatively that results in diminished vision. This is treated with laser surgery in humans which cannot be performed in dogs. Therefore, an alternative method for preventing or decreasing PCO must be found. A capsular tension ring (CTR) is a device that can be placed within the lens capsule, with the IOL, at the time of cataract surgery. Previous studies in humans have shown that CTRs significantly decrease PCO formation. We hypothesize that CTRs will significantly diminish PCO formation in canine lenses using an ex vivo model and in clinical canine

The pathological development of lens epithelial cells (LECs) leads to posterior capsular opacification (PCO). This studywas undertaken to investigate the effects of microRNA-486-5p (miR-486-5p) on TGF-b2-induced proliferation, invasionand epithelial-mesenchymal transition (EMT) in the lens epithelial cell line SRA01/04, and to explore the underlyingmolecular mechanisms. The expression of miR-486-5p in TGF-b2-induced SRA01/04 cells was down-regulated, and theexpression of Smad2, p-Smad2 and p-Smad3 was up-regulated. A dual-luciferase reporter assay revealed that miR-486-5pdirectly targets the 30-UTR of Smad2. MiR-486-5p mimic transfection markedly down-regulated the expression levels ofSmad2, thus inhibiting the expression of p-Smad2 and p-Smad3. MiR-486-5p overexpression in SRA01/04 cells markedlysuppressed TGF-b2-induced proliferation and invasion, inhibited protein expression of CDK2 and CDK4, down-regulatedfibronectin, a-SMA and vimentin and up-regulated E-cadherin; these effects were partly ...

Electrophysiology. Experiments were performed on posterior hypothalamic slices from 3- to 4-week-old male Wistar rats. After decapitation, the brain was placed in an ice-cold solution made up of (in mm): 208 sucrose, 26 NaHCO3, 10 glucose, 2.1 MgCl2, 1.8 KCl, 1.5 CaCl2, and 1.2 KH2PO4. The solution was bubbled to a pH of 7.4 with a mixture of 95% O2 and 5% CO2. Slices were cut at a thickness of 300-400 μm as described previously (Stevens and Haas, 1996) and transferred to artificial CSF (ACSF), which had the same composition as above except that the sucrose was replaced with 125 mm NaCl. The slices were held in ACSF at room temperature (22-24°C) for at least 1 hr before starting the recording. The slices were then transferred to a thermostat-controlled recording chamber, in which they were submerged in ACSF with a flow rate of 1.8-2.0 ml/min−1 and a temperature of 32-33°C. Intracellular recordings were obtained using sharp glass microelectrodes filled with K+acetate (4 m) with resistances ...

For many years, HSUS has supported a kill-all policy in regard to pit bulls from fight busts. It is an attitude that has been promoted by many animal control and humane societies as well. I remember volunteering at a county animal control for three years - the single most people-focused, temperamentally sound dog I met was a dog from a fight bust. I was told a whole host of reasons as to why, when the court case was over, she had to die. I bought it too, even though my heart was screaming at me that I was being stupid, that it was wrong to kill this beautiful, healthy, people-loving dog. That dog deserved so much better, she deserved a chance at life. Thousands of perfectly sound dogs have died because the animal welfare culture, specifically HSUS, said so, that because they were pit bulls and victims of fighting that they had no other worth than the landfill or incinerator. Wrong, wrong, wrong ...
Cataract surgery will not restore vision lost from other eye conditions such as macular degeneration, glaucoma, or diabetic retinopathy.. Your ophthalmologist will talk with you about the risks and benefits of cataract surgery.. Posterior Capsular Opacification. Your vision could become cloudy or blurry weeks, months, or years after cataract surgery. This is not unusual. Your doctor might call this a posterior capsular opacification (or PCO). Its also called secondary cataract or scar tissue. Its not like a scar you get on your skin. But because it happens after the eye has healed from cataract surgery, some people think of it as a scar. It happens when a membrane called the posterior capsule becomes cloudy. It might help to think of the posterior capsule as a transparent pocket. It holds your IOL in place. It also once held your eyes natural lens (what became the cataract) in place. If you notice cloudy vision again, you might need to have a laser procedure. The laser creates an ...
Cataract surgery is a very common procedure with low risks involved. Less than a single percent of patients will suffer from any serious complications that will necessitate further surgeries. If complications do arise, these are, more often than not, successfully treated through additional procedures.. While it is possible that your vision may get worse or that permanent damage may occur after the cataract surgery, these cases are extremely rare. Still, a comprehensive consultation with your eye doctor should be done so that you will be fully informed of all the possible risks.. Posterior Capsule Opacification. The most common risk that a cataract patient may encounter after surgery is the development of a condition called posterior capsule opacification, or PCO. In this condition, a portion of the capsule of your lens may thicken and lead to a cloudy vision. While some may mistake this as a sign of the cataract returning, it is actually cells growing at the back of the artificial lens.. This is ...
0024]Typically the human lens capsule of the present invention may be supported on a solid substrate such as a plastics or glass surface, e.g. the surface of a petri dish. Sigma ligands may be first identified as such by conducting, for example, a radioligand binding assay, such as described in WO 00/00599 to ascertain that the test agent is a sigma ligand, before carrying out the method as described above. Importantly, sigma radioligand binding assays determine only that an agent binds to sigma sites and not whether it acts as an agonist or antagonist in functional terms (whether it acts to stimulate or inhibit the receptor). In WO 00/00599 it was disclosed that different sigma receptor subtypes--or even binding pockets on the same receptor molecule--can act in opposite ways to either promote or suppress apoptosis (cell death).

The Gemini Refractive Capsule (Omega Ophthalmics) takes an open-source approach to providing the option of exchangeability to any modern lens design while also stabilizing ELP. The product is an implant that lines the circumference of the capsular bag and provides a defined plane in the middle of the capsule to securely hold a traditional IOL in place. The company is also developing a proprietary hydrophobic acrylic optic that could be used in conjunction with the Gemini Refractive Capsule, either alone or in combination with traditional IOLs, to create new optical systems for low-vision patients or simply to fine-tune refractive outcomes. Additionally, by keeping the capsular bag open, the Gemini Refractive Capsule has been shown to dramatically reduce posterior capsular opacification (PCO). Other nonrefractive devices, such as biometric sensors, are also being developed to fit inside the real estate that is protected by the Gemini Refractive Capsule. With a protected ...
Six rabbits underwent phacoemulsification with bilater implantation of an IOL. Postoperative power adjustment was performed using the femtosecond laser 2 weeks following implantation, in one eye. The animals were then followed clinically with slit lamp examination for an additional 4 weeks. The rabbits were then euthanized and the globes were enucleated. The globes were bisected coronally and gross examination and photographs from the posterior aspect were performed to assess anterior capsular opacification and fibrosis as well as posterior capsular opacification. After IOL explantation for power measurements, the globes were sectioned and processed for light microscopy following H&E staining ...
A common cataract surgery complications is a posterior capsule opacity in the lens implant. A procedure called a YAG laser capsulotomy can quickly and effectively restore vision following posterior capsular opacification.
YAG capsulotomies are routine procedures used to restore vision after the formation of a secondary cataract, also called posterior capsular opacification.
Intraocular lens coating compositions for reducing the risk of posterior capsule opacification are disclosed. The coating materials, which differ from the substrate material, consist essentially of at least two aryl acrylic hydrophobic monomers of the formula ##STR1##wherein:X is H or CH.sub.3 ;m is 0-10;Y is nothing, O, S, or NR wherein R is H, CH.sub.3, C.sub.n H.sub.2n+1 (n=1-10) iso OC.sub.3 H.sub.7, C.sub.6 H.sub.5, or CH.sub.2 C.sub.6 H.sub.5 ;Ar is any aromatic ring which can be unsubstituted or substituted with CH.sub.3, C.sub.2 H.sub.5, n-C.sub.3 H.sub.7, iso-C.sub.3 H.sub.7, OCH.sub.3, C.sub.6 H.sub.11, Cl, Br, C.sub.6 H.sub.5, or CH.sub.2 C.sub.6 H.sub.5.
Clouding of the portion of the lens covering (capsule) that remains after surgery, often called aftercataract (posterior capsular opacification). This is usually not a big problem and can be treated with laser surgery, if needed. The type of IOL may affect how likely it is to have clouding after surgery ...
After evaluating the emergency signs and a general physical examination, the eye examination begins with sharp eyesight. Patients can significantly reduce visual acuity and even sharp vision without light perception (blindness). There may be a pupil defect in the form of a decreased or missing light reflex on the anterior segment. On posterior segment may reveal damage to the optic nerve in the form of hyperemia and edema in acute conditions, which progress to pallor and atrophy in chronic conditions. These findings occur symmetrically and bilaterally. There may be damage to the retina and its surroundings, such as bleeding spots around the optic disc ...

Glycans are essential regulators of protein function and are now in the focus of research in many physiological and pathophysiological processes. There are numerous modes of regulating their biosynthesis, including epigenetic mechanisms implicated in the expression of glyco-genes. Since N-glycans located at the cell membrane define intercellular communication as well as a cellular response to a given environment, we developed a method to preferentially analyze this fraction of glycans. The method is based on incorporation of living cells into polyacrylamide gels, partial denaturation of membrane proteins with 3 M urea and subsequent release of N-glycans with PNGase F followed by HPLC analysis. Using this newly developed method, we revealed multiple effects of epigenetic inhibitors Trichostatin A, sodium butyrate and zebularine on the composition of N-glycans in human cells. The induced changes were found to be reversible after inhibitor removal. Given that many epigenetic inhibitors are currently

Ideally, the capsulorhexis diameter should be slightly smaller than the optic diameter so that we can achieve 360° overlap. But what if it doesnt? Well, it turns out that it is not that big of an issue because the capsule shrink-wraps in the post-op period and it makes the capsulorhexis diameter about 10% smaller --…
