SEATTLE —The incidence of microbial keratitis after laser vision correction is one in 6,300 patients, according to a poster presented here. Steven C. Schallhorn, MD, told Ocular Surgery News at the Association for Research in Vision and Ophthalmology meeting that he and colleagues were able to calculate this incidence by using a large cohort of consecutive patients who underwent refractive surgery from January 2008 to December 2012.
SEATTLE — The combination of ultra-high resolution adaptive optics scanning laser ophthalmoscope imaging with spectral domain optical coherence tomography can provide detailed assessment of the in vivo interplay of retinal vascular and neural pathology, according to a speaker here.“Microaneurysms are common and can be a hallmark sign of diabetic retinopathy,” Jennifer K. Sun, MD, said at the Association for Research in Vision and Ophthalmology meeting.

SEATTLE — The rate of infectious endophthalmitis after intravitreal anti-VEGF injection is low, according to a meta-analysis presented here in a poster. In cases that were reported over the past 7 years, the most common causative organisms were coagulase-negative staphylococci and Streptococcus species.
SEATTLE — Both selective and non-selective alpha blockers taken before cataract surgery were associated with intraoperative floppy iris syndrome in a retrospective study of a large Veterans Health Administration database, according to a poster here.“Altogether, complication rates were fairly low,” David E. Vollman, MD, told Ocular Surgery News at the Association for Research in Vision and Ophthalmology meeting.
SEATTLE — Fatigue-induced impairments in saccade velocity after prolonged strenuous exercise can be reversed by caffeine, according to a poster presented here.“It has been proven in primates that fatigue affects saccadic eye movement,” poster presenter Charlotte J. Connell told Ocular Surgery News at the Association for Research in Vision and Ophthalmology meeting. With that premise, the researchers randomized 10 cyclists to receive either placebo or caffeine during a 180-minute cycling protocol. Saccadic eye movements and global motion perception were assessed before and after the protocol.
SEATTLE — Both patients and surgeons are satisfied after bilateral implantation of an aspheric diffractive multifocal one-piece IOL, according to a poster presented here.The Tecnis multifocal one-piece IOL (ZMB00, Abbott Medical Optics) was bilaterally implanted in 106 patients with corneal astigmatism by surgeons who had not implanted this lens previously, and then both clinical and satisfaction assessments were made in a prospective, multicenter, open-label observation study.
SEATTLE — Once-daily 0.07% bromfenac ophthalmic solution safely reduces ocular inflammation after cataract surgery, according to a poster here. “Compared to placebo, low-concentration, modified bromfenac ophthalmic solution dosed once daily effectively and safely reduced ocular inflammation associated with cataract surgery,” James A. Gow and colleagues said in a poster presented at the Association for Research in Vision and Ophthalmology annual meeting.

SEATTLE — When considering using ocriplasmin for vitreomacular traction, the most important consideration is the size of the macular traction, but age, presence of epiretinal membrane and whether the eye is phakic also need to be taken into account, according to a speaker here. Speaking at the Cole Eye Institute Retina Summit held before the Association for Research in Vision and Ophthalmology meeting, Peter K. Kaiser, MD, said that if the macular adhesion is broad, patients did not do as well as patients with focal areas of adhesion.
SEATTLE — Despite what many have said, the Comparison of Age-Related Macular Degeneration Treatment Trials showed ranibizumab and bevacizumab are equivalent for visual acuity, according to an expert speaking here. “We are talking about a 0.5 D difference,” Daniel F. Martin, MD, said regarding visual acuity results in the CATT. “People see it the way they want to see it, but one line is really trivial. This is noise. There is no statistically significant difference at 2 years.”
Senju Pharmaceutical will co-develop and market Allegro Ophthalmics’ integrin peptide therapy in Japan under an agreement between the two companies, according to a joint news release.
