NEW JOURNAL STUDIES
Late IOL dislocation associated with PFX, glaucoma and zonular dehiscence at cataract surgery
This retrospective study included 84 patients (84 eyes) who underwent secondary IOL fixation surgery for late IOL dislocation. More than 60 percent of patients had pseudoexfoliation and nearly 37 percent had glaucoma at IOL repositioning. Nearly 37 percent had zonular dehiscence at cataract surgery. Primary placement of the IOL in the ciliary sulcus was associated with earlier IOL dislocation. Repositioning surgery using a posterior or anterior approach was successful in many cases. Journal of Cataract & Refractive Surgery, October 2010
Disc hemorrhage appears a risk factor for progression in POAG, NTG and PACG
This retrospective review included 2,417 patients with primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), or primary angle-closure glaucoma (PACG) who had an episode of disc hemorrhage. Over a mean follow-up of nine years, NTG had the highest incidence of disc hemorrhage (7 percent), followed by PACG (5.7 percent) and POAG (5.6 percent). Disc hemorrhage was associated with disease progression in all three glaucoma types. Clinical characteristics of the disc hemorrhage were also similar among the groups. Glaucoma, September 2010
Small head-to-head trial finds no difference between bevacizumab and ranibizuamab
This prospective, double-masked, randomized clinical trial compared outcomes in 15 patients with AMD treated with bevacizumab to seven patients treated with ranibizumab. At one year, there was no difference in visual and anatomic outcomes between the two groups. The bevacizumab group underwent an average of eight injections while the ranibizumab group underwent a mean of four injections (P=0.001). They conclude that further studies with larger sample sizes are warranted. Eye, Oct. 1, 2010 - early online publication
Meta-analysis: LASEK has no significant advantage over PRK for myopia
This meta-analysis evaluated 11 randomized controlled trials and one comparative study of LASEK and PRK for myopia and found no significant difference between the two procedures in terms of clinical outcomes. Postoperative pain, UCVA, reepithelialization time, and SE were similar. Less corneal haze was observed in LASEK-treated eyes at 1 and 3 months postop; however, there was no statistical difference between the groups after six months. Ophthalmology, October 2010
Long-term study finds photoscreening effective in detecting amblyopia in children
Researchers report on their nine-year experience using the MTI PhotoScreener to screen 147,809 preschool-aged children in the state of Iowa. The referral rate was 4.3 percent, and more than 75 percent of referred children received formal eye examinations. Amblyopia risk factors were found in more than 94 percent of examined children. The addition of a part-time follow-up coordinator in 2003 improved the overall follow-up rate from 47 percent to 81.3 percent. The annual cost of the volunteer-led screening was about $9 per child.

Study: AMD patients are not taking their AREDS vitamins
Investigators administered a survey to 64 consecutive patients with AMD seen at a tertiary referral center regarding their use of vitamin supplementation. Of the 40 patients who met the AREDS criteria for vitamin supplementation, 42.5 percent reported taking AREDS vitamins in the recommended dosages and 13 percent took less than the recommended dosage. Among patients using AREDS vitamins as recommended, 100 percent were return patients to the retina center. Most those not taking the supplement were new patients and 75 percent of them reported that vitamin supplementation had never been recommended to them. Retina Journal, September 2010
