Light sensors present in 2% of retinal cells relate to the body's internal clock and not to vision, according to research published in the journal PLoS ONE.

A lamellar sliver is a devastating complication resulting from recutting flaps during LASIK enhancement procedures.

An intellectual property database has already revealed great insights into R&D, and it opens up a whole new world of information, according to Dr Hermann Mucke.

The use of an artificial cornea in patients who have experienced multiple immunologic graft rejections is more likely to result in good-quality vision than is performing another corneal transplant.

The safety of intracameral moxifloxacin (Vigamox, Alcon Laboratories) for post cataract surgery endophthalmitis prophylaxis was investigated in a prospective, randomized, controlled study. Statistical analyses of multiple postoperative outcome measures demonstrated no significant differences between patients who received intracameral moxifloxacin and controls treated with intracameral balanced salt solution.

Acuvue Oasys, a contact lens designed for astigmatic eyes, has been introduced at the American Optometric Association (AOA) annual meeting by Vistakon, a division of Johnson & Johnson Vision Care.

Alcon and Advanced Medical Optics (AMO) are to share proprietary information on their designs for intraocular lenses (IOL).

Durezol (difluprednate ophthalmic emulsion; Sirion Therapeutics) 0.05%, a topical steroid, has received US Food and Drug Administration (FDA) approval for the treatment of postoperative ocular inflammation and pain.

High caffeine intake is associated with an increased risk of high-tension primary open angle glaucoma (POAG) in subjects with a positive family history of glaucoma, according to a study published in the May 2008 issue of Investigative Ophthalmology & Visual Science.

Oxidative stress may play a role in the pathogenesis of primary open angle glaucoma (POAG), according to a study published in the June/July 2008 issue of the Journal of Glaucoma.

A revolutionary, needle-free technology that has been designed to deliver retina therapies non-invasively, to the back of the eye, has been launched.

Surgical therapy for age-related macular degeneration in the form of macular translocation, injection of tissue plasminogen activator, and gas tamponade provides some improvements in visual acuity for patients whose conditions do not respond to the anti-vascular endothelial growth factor drugs.

Fundus autofluorescence imaging, one of the modes available in a new instrument (Spectralis HRA+OCT, Heidelberg Engineering), enhances its utility as a diagnostic device and a tool for monitoring therapy of patients with retinal and macular diseases.

Trivaris (triamcinolone acetonide injectable suspension; Allergan), a synthetic glucocorticoid corticosteroid, has been approved by the FDA for the treatment of inflammatory ophthalmic conditions.

Animals undergoing lens removal surgery were treated with non-steroidal anti-inflammatory drugs pre- and postoperatively. On the first day after surgery, aqueous humor samples were taken at times corresponding to trough drug levels. The mean aqueous prostaglandin E2 concentration was significantly lower in animals being treated with ketorolac 0.4% (Acular LS, Allergan) compared with those receiving bromfenac 0.09% (Xibrom, ISTA Pharmaceuticals).

Few well-designed studies evaluate endophthalmitis prophylaxis. Available evidence suggests a role for intracameral cefuroxime. The benefit must be weighed against the potential risk of errors in formulation, however.

In a point-counterpoint debate at the annual meeting of the American Academy of Ophthalmology, one clinician contended that the rate of post-LASIK ectasia is declining and that, with careful screening and other preparatory steps, the rate of ectasia can be kept very low. The counter-argument by another clinician suggested that the multifactorial basis of ectasia as well as unknown risk factors make it impossible to prevent a certain percentage of cases from developing.

In a prospective, randomized, contralateral study of 75 adults, eyes in which an aspheric IOL (AcrySof IQ model SN60WF, Alcon Laboratories) had been implanted demonstrated better mesopic contrast sensitivity, significantly less spherical aberration, and significantly less total higher-order aberrations compared with eyes in which a standard spherical IOL (AcrySof model SA60AT, Alcon Laboratories) had been implanted. Cumulative uncorrected visual acuity and best-corrected visual acuity were equivalent between both groups.

A new study shows that costs associated with glaucoma will more than double by 2025.

OT134, a laser therapy for the reduction of intraocular pressure, has completed the follow-up period of its first human clinical study.

The EyeRoute Image Management System, which provides a remote view of a Spectral Domain OCT system, has been introduced by Topcon Medical Systems.

A new model can predict the percentage of people who will develop advanced age-related macular degeneration (AMD) at various ages. The model, which is based on well-established risk factors for the disease such as age, smoking, and genetics, considers high-risk, intermediate-risk, and low-risk genotypes. Genotypes are more predictive of the risk of developing advanced AMD than is age.

Scientists who produced a visual prosthesis giving rudimentary sight to the blind are to receive the Joseph von Fraunhofer Prize 2008 in recognition of their achievement.

A research project developing new technologies for laser treatments for the retina has been launched by the German Federal Ministry for Education and Research.

Eating a diet rich in omega-3 fatty acids seems to correlate with a low incidence of age-related macular degeneration (AMD), according to a study published in the June 2008 issue of the Archives of Ophthalmology.

Peeling the internal limiting membrane (ILM) may reduce the rate of premacular fibrosis (PMF) formation, according to a study published in the June 2008 issue of Retina.

The higher level of advanced glycation end products (AGE) in senile diabetic patients may correlate to a higher rate of cataract development, according to a study published in the May?June 2008 issue of the Journal of Diabetes and its Complications.

Ophthalmology organizations voice concerns to FDA on contact lens safety.

Further study is needed to establish the role of multifocal IOLs in eyes with glaucomatous damage, according to Ike Ahmed, MD, who was speaking during the glaucoma subspecialty day at the annual meeting of the American Society of Cataract and Refractive Surgery.

Following positive clinical trial results, Allergan, the makers of bimatoprost, are submitting a new drug application (NDA) to the US Food and Drug Administration (FDA), seeking a new indication for the prostaglandin analogue as an eyelash growth stimulant.
