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.

Low diastolic ocular perfusion pressure linked to increased POAG risk

AO LogoLow diastolic ocular perfusion pressure linked to increased POAG risk
Investigators evaluated the association of ocular perfusion pressure status with primary open-angle glaucoma (POAG) in the Thessaloniki Eye Study population. They found an association of borderline significance between low diastolic ocular perfusion pressure and POAG. Subgroup analyses confirmed this association in subjects treated for systemic hypertension. No association was found between diastolic ocular perfusion pressure and PEXG. Additionally, there was no association between systolic ocular perfusion pressure and OAG, POAG or PEXG, regardless of the use of antihypertensive treatment.

Femtosecond laser pretreatment reduces effective phaco time

AO LogoFemtosecond laser pretreatment reduces effective phaco time
This prospective study compared the effective phacoemulsification (EPT) time between patients (150 eyes) who underwent pretreatment with the femtosecond laser followed by cataract extraction, and those who had conventional phaco surgery (51 eyes). Mean EPT was reduced by 84 percent in the femtosecond group compared with controls. Using improved lens fragmentation algorithms and a 20-gauge phaco tip in a subgroup, the percentage increased to 96.2 percent. Additionally, 30 in the laser group had 0 EPT, compared with no cases in the control group. The femtosecond group also experienced a 36.1 percent reduction in endothelial cell loss.

Prior trabeculectomy may contribute to refractive surprise post cataract surgery

AO LogoPrior trabeculectomy may contribute to refractive surprise post cataract surgery
Investigators retrospectively compared outcomes in patients who underwent cataract surgery at least three months after trabeculectomy to those with either medically controlled glaucoma or no glaucoma. The trabeculectomy group had significantly greater refractive error than expected compared with each of the two control groups undergoing cataract surgery (P = .005). The refractive difference correlated to IOP change, with 2 mm Hg of IOP rise resulting in a −0.36-diopter shift, suggesting that IOP increase after phaco causes axial length to increase which results in myopic shift.

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.

Topical tacrolimus effective for refractory inflammatory ocular surface diseases

AO LogoTopical tacrolimus effective for refractory inflammatory ocular surface diseases
This retrospective review evaluated the efficacy of 0.02% tacrolimus ointment applied one to three times per day, depending on disease severity, for up to 31 months in 12 consecutive patients previously treated with steroid therapy. Treatment showed an immunosuppressive effect in all disease types, especially scleritis and Mooren ulcer. In chronic cicatrizing conjunctivitis, simultaneous tacrolimus while tapering steroid therapy suppressed inflammatory relapse. Tacrolimus did not elevate IOP as do steroids, and no side effects were observed.
