Study: Visual field loss impacts driving performance
August 1st 2014Results of a randomized study show both superior and inferior visual field defects impair drivers’ performance on the computerized Hazard Perception Test. However, superior visual field loss is associated with significantly greater worsening than inferior visual field loss.
Patient expectations high as level of surgery advances
August 1st 2014In this ongoing series of one-on-one interviews with key ophthalmic leaders, J.C. Noreika, MD, MBA, talks with Samuel Masket, MD, clinical professor of ophthalmology, David Geffen School of Medicine, Jules Stein Eye Institute, University of California, Los Angeles (UCLA). In his practice, Dr. Masket sees a high volume of patients referred for dysphototopsia and addresses issues related to the condition. Dr. Masket also highlights some of his many achievements and contributions to cataract and refractive surgery and tracks the field’s trends-from the infancy of phacoemulsification and lens implant cataract surgery to femtosecond lasers and extended depth-of-focus IOLs.
Episcleral venous fluid wave offers intraoperative guide during canal-based surgery
July 29th 2014Observation of the episcleral venous fluid wave while performing canal-based glaucoma surgery provides intraoperative confirmation of accurate device placement, correlates with the extent of surgically induced canal cleavage, and may be a prognostic indicator for surgical success, said Ronald L. Fellman, MD.
Iodine may alleviate retinitis pigmentosa swelling
July 29th 2014Researchers from Massachusetts Eye and Ear, Harvard Medical School, and Boston University School of Medicine have found that the extent of retinal swelling due to cystoid macular edema (CME) was inversely related to dietary iodine intake in patients with retinitis pigmentosa (RP).
Why balanced tip increases phaco with less energy
July 22nd 2014A new surgical advance-the Intrepid Balanced phacotips designed specifically for microcoaxial torsional ultrasound-has been found to have a significantly increased emulsification effect and markedly reduced shaft action compared with the traditional Kelman flared and mini-tips, said Khiun Tjia, MD.
Examining advances in AAV vector for retinal gene therapy
July 15th 2014Much work is being done with Adeno-associated virus (AAV) vectors for application in retinal gene therapy, with modifications being made to the capsid and genome of the vector to generate novel variants with unique transduction profiles, according to Shannon Boye, PhD.
