BACKGROUND: Postoperative endophthalmitis after cataract surgery is a severe eye infection that can lead to irreversible blindness in the affected eye. The characteristics, treatment and prognosis of this disease vary because of its association with different pathogens. Here, we report what is possibly the first case of endophthalmitis after cataract surgery to be associated with the rare pathogen Earliella scabrosa. CASE PRESENTATION: A 56-year-old man from Hainan Island (China) with a history of phacoemulsification and type II diabetes mellitus underwent intraocular lens (IOL) implantation...

Although the possibility of using drug-loaded ophthalmic lens to promote sustained drug release has been thoroughly pursued, there are still problems to be solved associated to the different alternatives. In this work, we went back to the traditional method of drug loading by soaking in the drug solution and tried to optimize the release profiles by changing the temperature and the time of loading. Two materials commercially available under the names of CI26Y and Definitive 50 were chosen. CI26Y is used for intraocular lenses (IOLs) and Definitive 50 for soft contact lenses (SCLs)...

BACKGROUND/PURPOSE: To describe a novel use of the flexible nitinol loop membrane scraper (FINESSE Flex loop; Alcon, Fort Worth, TX) for rescue and refixation of a dislocated intraocular lens (IOL). METHODS: A 27-gauge nitinol flex loop was used to lasso each haptic of a dislocated 3-piece IOL. By retracting the loop, the haptic could be effectively locked to the instrument and externalized through a scleral tunnel, thereby fixating it to the sclera in a sutureless fashion...

We have developed a simple method for the induction of cataracts in adult zebrafish using hydrogen peroxide. Our method uses a corneal puncture followed by intraocular injection of hydrogen peroxide into the anterior chamber. The procedure can be done rapidly, forming a highly opaque cataract almost immediately, and fish recover quickly. The optical clarity of the lens is gradually regained over time, showing the innate ability of zebrafish to regenerate healthy lens tissue. This technique provides a simple in vivo system with which to assess mutant strains or targeted disruptions to genes expressed in the lens...

Mineo Ozaki
The most important characteristic of exfoliation syndrome (XFS) is that it involves a greater risk of developing glaucoma. In comparison with other forms of open-angle glaucoma, exfoliation glaucoma (XFG) is more resistant to medical therapy and progresses faster. Possible pathological mechanisms of glaucoma development in XFS comprise: (1) elevated intraocular pressure (IOP) caused by functional impairment of aqueous humor outflow due to deposition of exfoliation material (XFM) in the trabecular meshwork and trabecular cell dysfunction, (2) XFS-associated connective tissue elastosis leading to structural and functional alterations of the lamina cribrosa which increases the vulnerability toward elevated IOP and development of glaucomatous optic neuropathy, (3) elevated IOP due to closure of the anterior chamber angle accompanied by forward displacement of the crystalline lens due to zonular weakness, (4) presumable primary functional impairment of retinal ganglion cells...

We report the case of an emmetropic 32-year-old female with decreased uncorrected visual acuity and diplopia due to intermittent episodes of spasm of the near reflex. Neurologic, general, and ophthalmic examination could not find an organic cause. Attempts at spontaneous recovery, psychogenic therapy, and cycloplegic therapy were unsuccessful and the symptoms persisted for almost 5 years, leading to psychogenic distress. Final treatment with refractive lens exchange and implantation of a toric trifocal intraocular lens resolved the spasm of the near reflex, resulting in an uncorrected distance and near visual acuity of 20/20...
