October 22nd 2008The combination of low antioxidant levels and exposure to sunlight may damage vision and also is linked to age-related macular degeneration, according to a study published in the October issue of the Archives of Ophthalmology.
Sirion Therapeutics launches corticosteroid for postoperative ocular inflammation and pain
October 15th 2008Sirion Therapeutics Inc. announced that a difluprednate ophthalmic emulsion 0.05% (Durezol) indicated for the treatment of inflammation and pain associated with ocular surgery is now commercially available.
Viscoelastic receives FDA approval
October 15th 2008Advanced Medical Optics (AMO) announced that the FDA has granted premarket approval of a viscoelastic (Healon D), a clear dispersive ophthalmic viscosurgical device (OVD) for use as a surgical aid in cataract extraction, IOL implantation, corneal transplant, and glaucoma filtration surgery.
Bascom Palmer gains top spot in annual survey
October 15th 2008The Bascom Palmer Eye Institue, University of Miami School of Medicine, sweeps three categories-Best Overall, Best Residency, and Best Clinical (Patient Care) Programs-in the 13th annual Ophthalmology Times' Best Programs survey. The Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, takes the top honors for Best Research Program. Chairpersons and residency directors from U.S. departments of ophthalmology ranked programs nationwide.
Telemedicine: well-established in ROP
October 15th 2008The value of telemedicine is well established, but some limitations in image quality do exist. An objective evaluation of the images overrides the limitations, however. Imaging provides a great opportunity for research. More data on cost effectiveness of various screening modalities are needed in patients with retinopathy of prematurity.
Demands: Striving for sense of balance in personal and professional lives
October 15th 2008Ophthalmic practice administrators often find heavy demands on their time and attention and so, like many managers, risk losing sight of what's important in the rest of their lives. But while it isn't possible to avoid the stresses and strains that accompany the job, there are ways administrators can maintain or restore a sense of balance in their lives.
Details key to increasing patient volume, maintaining ophthalmic business
October 15th 2008Reimbursements for ophthalmic practices are steadily declining while costs are going ever higher, leaving practices scrambling as never before to find new sources of revenue and ways of cutting costs. But unless these goals are approached wisely they can lead to stress among both staff and doctor.
2008's new modifiers should be used correctly
October 15th 2008Current Procedural Terminology (CPT) is updated regularly, often in response to difficulties reported by practitioners. Practices that fail to keep up with the changes experience negative consequences on revenue and compliance. Staying familiar with changes in CPT can be very useful, and potentially quite rewarding.
Researchers examine effect of horizontal strabismus surgery on refraction
October 15th 2008Significant changes in cylindrical measurements were observed following unilateral horizontal strabismus surgery in a retrospective study. In addition, investigators found clinically significant changes in a large number of operated eyes as well as a portion of control eyes.
Ab-interno trabeculectomy with novel ablative device encouraging based on case series outcomes
October 15th 2008Outcomes data for ab-interno trabeculectomy with a novel ablative device (Trabectome, NeoMedix) to ablate thermally the trabecular meshwork consist of case series. So far, this procedure has been associated with favorable IOP lowering, but a direct comparison with standard trabeculectomy is needed, according to one glaucoma specialist.
Cell loss, retinal thinning found after excitotoxic damage
October 15th 2008A study in a rat model found retinal ganglion cell loss and retinal thinning following excitotoxic damage. This finding has led researchers to speculate that axonal damage and excitotoxicity are related, and that the connection may be through the Wallerian degeneration gene. Future research into this pathway could lead to new forms of treatment for glaucoma and other neurologic diseases.
Mini glaucoma shunt viable surgical alternative
October 15th 2008Surgical outcomes were compared in a retrospective study of 76 eyes with a miniature glaucoma shunt (Ex-PRESS, Optonol) implanted and 77 eyes that underwent standard trabeculectomy. The two procedures were associated with similar IOP-lowering efficacy, but the shunt procedure had a benefit for reducing the risk of hypotony.
Dry eye a serious public health problem
October 15th 2008Considerable progress has been made in recent years in the understanding of the epidemiology of dry eye disease. Here, two doctors discuss some of the studies that have helped ophthalmologists understand the prevalence, burden, and risk factors of dry eye disease. They also highlight how improved diagnosis will have a significant effect on the quality of life of patients with dry eye.
Flap creation technique, ablation depth affect biomechanical results
October 15th 2008A retrospective study of eyes undergoing wavefront-guided PRK, LASIK with a mechanical microkeratome, or LASIK with a femtosecond laser shows that biomechanical changes are affected by flap creation technique and ablation depth.
Concept of mixing and matching various IOLs not always advantageous, study shows
October 15th 2008Is bilateral implantation of an IOL better than contralateral "mixing and matching" of lenses? In one cross-study comparison, postoperative visual outcomes were examined to compare the effectiveness of bilateral implantation of an apodized diffractive IOL versus contralateral implantation of one apodized diffractive IOL and one refractive zonal progressive IOL.
Study supports safety of femtosecond LASIK
October 15th 2008A retrospective study evaluated complications and associated outcomes in eyes that underwent LASIK with femtosecond laser flap creation at a university-based refractive surgery center. A direct or indirect complication due to flap creation occurred in 44 (0.92%) of 4,772 eyes; there was no loss of best spectacle corrected visual acuity in any of the 44 eyes.
Aberrometer aims to improve refractive, cataract outcomes
October 15th 2008A Talbot-Moiré wavefront aberrometer developed for use during cataract surgery is being investigated for its potential to enhance the accuracy of astigmatic correction with limbal relaxing incisions, toric IOL alignment, and IOL power selection.
Collagen crosslinking shows promise for keratoconus
October 15th 2008Accumulating experience with corneal collagen crosslinking indicate it is a safe and effective treatment for arresting progression of keratoconus. However, further studies are needed to better characterize its indications and contraindications.
Surface ablation does not prevent ectasia in forme fruste keratoconus eyes in review
October 15th 2008Review of a small series of eyes shows surface ablation procedures do not eliminate the risk of postoperative ectasia in eyes with forme fruste keratoconus, even in eyes without other ectasia risk factors.
