To assess resident surgical experience in vitreoretinal surgery (VRS) in the United States. ⋯ This self-reported electronic survey of third-year residents suggested that VRS experience at ACGME-accredited programs as primary surgeon was suboptimal for surgeries. A modest majority of residents reported comfort and satisfaction with VRS training for surgery, but a majority was satisfied and had adequate experience with office procedures such as intravitreal injection and laser treatment. Unfortunately, the majority of residents were unaware of the actual numeric ACGME VRS requirements for ophthalmology residency programs.

To report the immediate postoperative complications and the 6- and 12-month clinical results in a large series of cases undergoing the new triple-procedure Descemet's stripping automated endothelial keratoplasty (DSAEK) and concurrent cataract surgery. ⋯ The new triple-procedure DSAEK combined with cataract surgery provides rapid visual recovery and allows selection of an appropriate intraocular lens. Dislocations are rare (1.8%) and primary graft failure did not occur.

To assess trends in tenure for chairs of academic departments of ophthalmology and to assess characteristics that may be correlated with longevity. ⋯ The average turnover rate for chairs of departments of ophthalmology has shown a slight upward trend over the last 25 years with a corresponding decrease in mean tenure length. Although this trend is not particularly alarming compared with those of other disciplines, academic leaders must be aware of this trend to estimate future leadership needs and to take steps to ensure tenure length does not decrease in such a way that it hinders the field.

To investigate whether nasal peripapillary retinal nerve fiber layer (RNFL) attenuation is associated with visual field loss attributed to the anti-epileptic drug vigabatrin. ⋯ Vigabatrin-attributed visual field loss is associated with a characteristic pattern of RNFL attenuation: nasal quadrant thinning and normal temporal quadrant thickness with, or without, superior or inferior quadrant involvement. Nasal attenuation may precede visual field loss. Ocular coherence tomography of the peripapillary RNFL should be considered in patients previously exposed to vigabatrin. It should also be considered at baseline and follow-up in those commencing vigabatrin for treatment of epilepsy or in trials for anti-addiction therapy. The pattern of RNFL thinning seems to be a useful biomarker to identify vigabatrin toxicity.

Multicenter Study
Prevalence of diabetic retinopathy in rural China: the Handan Eye Study.
To describe the age- and gender-specific prevalence, characteristics, and severity of diabetic retinopathy (DR) in a rural population in northern China. ⋯ Our study reports a high prevalence of DR among adults 30 years and older with diabetes in rural China. On the basis of estimates obtained from our study, we projected that in rural China, 21.1 million persons aged 30+ years have diabetes and 9.2 million have DR, including 1.3 million with vision-threatening DR. There is a pressing need for appropriate screening and management of diabetes and its complications in rural China.
