Office-based vitrectomy: proceed with caution

AsianOphthalmology Alliance logo Office-based vitrectomy: proceed with caution

In a pro/con session during AAO 2013 Retina meeting, Thomas M. Aaberg Jr, MD, and Steven T. Charles, MD, argued the merits of office-based vitrectomy.

Rationale for. Primary reasons for making the switch include cost, convenience, and control, Dr. Aaberg said. Proper patient and case selection is essential, he cautioned. With that as the starting point, “In every case we’ve performed, we’ve been able to achieve all of our surgical goals,” he added.

He noted that safety (more…) (636)

FDA accepts Regeneron’s Eylea sBLA for standard review

AsianOphthalmology Alliance logo FDA accepts Regeneron’s Eylea sBLA for standard review

The supplemental Biologics License Application (sBLA) on Eylea intravitreal injection (aflibercept, Regeneron, Tarrytown, N.Y.) for the treatment of diabetic macular edema (DME) has been accepted by the Food and Drug Administration, with a targeted Prescription Drug User Fee Act date of August 18, 2014.

The submission was based on positive data from Regeneron’s VIVID and VISTA studies. Eylea is currently approved in the U.S. for neovascular age-related macular degeneration and for macular edema following central retinal vein occlusion.

NSAIDs Speed Central Serous Choroidopathy Recovery

AsianOphthalmology Alliance logo NSAIDs Speed Central Serous Choroidopathy Recovery

Patients with central serous choroidopathy treated with nonsteroidal anti-inflammatory drug (NSAID) eyedrops recover faster than when they are not treated, according to a new study.

“We found that we could cut the average time to resolution by 50% with the NSAID eyedrops, which is the way we have been treating patients in our own practice,” said Michael Singer, MD, from Medical Center Ophthalmology in San Antonio.

He presented the results here at the American Academy of Ophthalmology 2013 Annual Meeting.

Central serous choroidopathy is characterized by spontaneous serous detachment of the neurosensory retina in the macular region, with or without retinal pigment epithelium detachment. Its cause is not known, but one theory suggests that increased (more…) (864)

First large population-based study investigating long-term risks supports need for ophthalmologic follow-up of children and adults born before 32 weeks of gestation

SAN FRANCISCO – Nov. 7, 2013 – Children born extremely prematurely have up to a 19 times greater risk of retinal detachment later in life than peers born at term, according to a Swedish study published this month in Ophthalmology, the journal of the American Academy of Ophthalmology. In the first large population-based, long-term investigation of the association between preterm birth and later retinal detachment, (more…) (892)

Anti-VEGFs possibly linked to increased heart attack risk

AO LogoAnti-VEGFs possibly linked to increased heart attack risk
This large retrospective study examined health records from Western Australian eye clinics to determine the risk of thromboembolic and gastrointestinal bleeding events in the 12 months after injections of bevacizumab or ranibizumab, compared with photodynamic therapy and untreated community controls. Though all adverse events were rare, anti-VEGF-treated patients were 2.3 times more likely to have a heart attack compared with controls. There was no difference in adverse events between bevacizumab and ranibizumab (1.6 and 2.1 events/100 persons, respectively). It’s unclear if the increased risk is associated with AMD itself or anti-VEGF treatment.

Delayed-onset endophthalmitis associated with better visual outcomes

AO LogoDelayed-onset endophthalmitis associated with better visual outcomes
This large retrospective series included all patients treated for culture-proven endophthalmitis after cataract surgery at a single university center between 2000 and 2009. Patients with delayed-onset endophthalmitis (>6 weeks after surgery) generally presented with better initial visual acuities, had a lower frequency of hypopyon, and better visual outcomes compared to acute-onset patients (≤6 weeks after surgery). Propionibacterium acnes and coagulase-negative Staphylococcus species were the most common organisms cultured in both groups and were associated with the best visual acuity outcomes in both groups.

AREDS formula requires tinkering

AO LogoAREDS formula requires tinkering
Five-year results from the AREDS2 study shows that adding lutein and zeaxanthin, and/or omega-3 fatty acids to the original AREDS formula did not further reduce the risk of AMD progression. However, they found some benefit in two subgroups: Subjects who took an AREDS formulation with lutein and zeaxanthin but no beta-carotene cut their risk by about 18 percent, while those who had very little lutein and zeaxanthin in their diets but took an AREDS formulation with lutein and zeaxanthin were about 25 percent less likely to develop advanced AMD compared with participants with similar dietary intake who did not take lutein and zeaxanthin. The authors recommend a new formula consisting of 400 IU of vitamin E, 500 mg vitamin C, 10 mg lutein and 2 mg zeaxanthin, 80 mg zinc and 2 mg copper.

Short-term external buckle shows promise for retinal detachment

AO LogoShort-term external buckle shows promise for retinal detachment
This retrospective case series reports two-year outcomes in 31 patients (33 eyes) with a rhegmatogenous retinal detachment with inferior retinal breaks. The external buckle consisted of a 505 sponge sutured along the blunt side of a 279 tyre. It was deeply embedded into the inferior fornix without suture after pneumatic retinopexy. The buckle remained in place for three days. Twenty-nine eyes achieved successful reattachment within six months with no more treatment. While the procedure failed in four eyes, reattachment was achieved with further treatment.

Longer axial length may be protective against diabetic retinopathy

AO LogoLonger axial length may be protective against diabetic retinopathy
This literature review evaluated the potential mechanisms, both refractive and structural, by which myopia protects against diabetic retinopathy. Longer axial length was the only variable consistently associated with a lower risk and severity of diabetic retinopathy in patients with myopia. The authors speculate that the decrease in blood flow and/or increase in ocular volume associated with increased axial length may be the mechanism for this protective effect.
