Rate of endophthalmitis after cataract surgery remains low

WAIKOLOA, Hawaii — Endophthalmitis after cataract surgery is uncommon, but it does happen, according to a speaker, with reported rates varying from 0.03% to 0.15%.When looking back at a single institution’s experience over a 15-year period during which nearly 60,000 cataract surgeries were performed, only 16 cases (0.03%) were identified, OSN Retina/Vitreous Board Member Andrew A. Moshfeghi, MD, MBA, said at Hawaiian Eye 2013.

Study: Pseudophakic dysphotopsia impedes function

WAIKOLOA, Hawaii — Researchers have found a correlation between pseudophakic dysphotopsia and impeded function, suggesting that the unwanted images are more than just an annoyance, according to a speaker here.Of 2,953 pseudophakic candidates considered for a visual quality study, only 70 met the criteria of having uncomplicated surgery, 20/20 results and no obvious ocular disease — no dry eye, no posterior capsule opacification (PCO), no blepharitis and no ocular complaint.

OCT may detect pre-perimetric changes in glaucomatous eyes

WAIKOLOA, Hawaii — Optic nerve head microcirculation is reduced in glaucoma patients, a speaker said here.“Conventionally, OCT is used to measure structure with micron precision, and that has been very useful in terms of characterizing the structure of the optic nerve head, the nerve fiber layer and the ganglion cell complex,” David Huang, MD, PhD, said at Hawaiian Eye 2013. “We developed a technique where we decomposed the OCT image into several spectral bands and analyzed them separately and recombined them to enhance a signal of flow.”

Goniotomy, trabeculotomy produce most successful results in pediatric glaucoma

WAIKOLOA, Hawaii — Goniotomy and trabeculotomy are the most effective surgical methods for infantile glaucoma, a speaker said here.“The first thing that’s most important in these surgeries is visualization,” Ken K. Nischal, MD, FRCOphth, said at Hawaiian Eye 2013. “It’s really important to understand that the goniolens you use will affect how easy or how difficult the procedure becomes.”

Diagnostic vitrectomy for uveitis indicated to obtain tissue for biopsy

WAIKOLOA, Hawaii — The need for a biopsy specimen in a patient with uveitis is an indication for diagnostic vitrectomy, a somewhat technique-based but mostly disease-based procedure, according to a speaker.“Figuring out the disease and what you need to do to control it is an essential part of the surgery, because the disease, in many cases, is going to be ongoing even after the surgical procedure,” Janet L. Davis, MD, told colleagues at Retina 2013.

Small globe size, high concentration of VEGF in vitreous may be risk factor for early AMD

HYDERABAD, India — Small globe size, possibly in correlation with a thicker vitreous and a higher concentration of VEGF, may be a major risk factor for early age-related macular degeneration, according to a speaker here. “In the Beijing Eye Study, hyperopia, short interscleral spur distance and small optic disc size, besides older age, were found to be the main risk factors associated with early AMD. This points to a small globe size, and we may speculate that the vitreous plays a role,” Jost B. Jonas, MD, said at the joint (Read more...)
