REVIEW
Laura E Downie, Ljoudmila Busija, Peter R Keller
BACKGROUND: An intraocular lens (IOL) is a synthetic lens that is surgically implanted within the eye following removal of the crystalline lens, during cataract surgery. While all modern IOLs attenuate the transmission of ultra-violet (UV) light, some IOLs, called blue-blocking or blue-light filtering IOLs, also reduce short-wavelength visible light transmission. The rationale for blue-light filtering IOLs derives primarily from cell culture and animal studies, which suggest that short-wavelength visible light can induce retinal photoxicity...

A 47-year-old male presented with bilateral 4 + circulating pigment in the anterior chamber, diffuse iris transillumination, dilated pupils unresponsive to light, and high intraocular pressure (IOP) levels in both eyes. Visual acuity and IOP improved bilaterally with topical steroid and antiglaucomatous therapy. In the 10th month, bilateral cystoid macular edema (CME) was developed and resolved after subtenon triamcinolone injections. CME recurred after cataract surgery in the right eye which was treated with intravitreal dexamethasone implant injection...

Purpose: To report the application of 25 MHz B-scan ultrasonography (MHzB) to determine the integrity of the posterior capsule (PC) in posterior polar cataract (PPC). Methods: Patients with whom PPC was clinically diagnosed using slit lamp microscopy who underwent 25 MHzB before phacoemulsification were retrospectively reviewed. The status of the PC was determined by 25 MHzB before phacoemulsification and confirmed during cataract surgery. Results: In total, 21 eyes in 14 clinically diagnosed PPC patients were enrolled in this study...

BACKGROUND: This meta-analysis evaluated the effectiveness and safety of dexamethasone (DEX) implant and intravitreal anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular edema (DME). METHODS: The PubMed, Embase, clinicaltrials.gov website and Cochrane Library databases were comprehensively searched for studies comparing DEX implant with anti-VEGF in patients with DME. Best-corrected visual acuity (BCVA), central subfield thickness (CST) and adverse events were extracted from the final eligible studies...

Several mutations associated with congenital cataracts in human beings target conserved arginine residues in αA-crystallin. The N-terminal region of αA-crystallin is a "mutational hotspot," with multiple cataract-related mutations reported in this region. Two mutations at arginine 21 in the N-terminal domain of αA-crystallin - αA-R21L and αA-R21W have been associated with congenital cataract. A third mutant of R21, αA-R21Q, was recently identified to be associated with congenital cataract in a South Australian family...

With the prominent progress of biomedical engineering, materials with high biocompatibility and versatile functions are urgently needed. So far, hierarchical structures in nature have shed some light on the design of high performance materials both in concept and implementation. Inspired by these, the hierarchical micro-/nanostructures of human hair are explored and human hair is further broken into hierarchical microparticles (HMP) and hierarchical nanoparticles (HNP) with top-down procedures. Compared with commercialized carriers, such as liposomes or albumin nanoparticles, the obtained particles exhibit high hemocompatibility and negligible immunogenicity...

MYH9-related disease is an autosomal dominant disorder caused by mutations of the MYH9 gene, which encodes the non-muscle myosin heavy chain IIA on chromosome 22q12. It is characterized by congenital macrothrombocytopenia, bleeding tendency, hearing loss, and cataracts. Nephropathy occurs in approximately 30% of MYH9-related disease in a male patient carrier of a de novo missense mutation in exon 1 of the MYH9 gene [c.287C > T; p.Ser(TCG)96(TTG)Leu]. He presented all phenotypic manifestations of the disease, but cataracts...

Robert Ritch
Exfoliation syndrome (XFS) is characterized by numerous ocular manifestations, the most important of these being glaucoma and cataract. Its ocular manifestations affect all of the structures of the anterior segment as well as conjunctiva and orbital structures. Exfoliation material is seen most prominently as characteristic white deposits on the anterior surface of the lens and the pupillary border of the iris. Both open-angle and angle-closure glaucoma are intimately associated with XFS. Other findings include zonular disruption, iris sphincter fibrosis, keratopathy, ocular surface disease, and retinal vein occlusion...

BACKGROUND: In developed countries, genetically inherited eye diseases are responsible for a high percentage of childhood visual impairment. We aim to report our experience using preimplantation genetic diagnostics (PGD) in order to avoid transmitting a genetic form of eye disease associated with childhood visual impairment and ocular cancer. MATERIAL AND METHODS: Retrospective case series of women who underwent in vitro fertilization (IVF) and PGD due to a familial history of inherited eye disease and/or ocular cancer, in order to avoid having a child affected with the known familial disease...
