Purpose: To assess the repeatability of axial biometry of the entire eye using ultra-long scan depth optical coherence tomography (OCT) and to investigate the agreement with IOLMaster measurements (Carl Zeiss Meditec).Design: Prospective, observational case series.Methods: There were 37 adult subjects enrolled in group 1 and 12 adult subjects enrolled in group 2. Using ultra-long scan depth OCT, the left eyes of these groups were measured in 2 separate sessions. The images were processed by a manual method and custom-developed automatic software. A model eye was imaged for verification. The subjects in group 2 were imaged using ultra-long scan depth OCT (Read more...)

High Prevalence of Demodex brevis Infestation in Chalazia – Corrected Proof
Purpose: To investigate the correlation between demodicosis and chalazia in patients with the latter.Design: Prospective, observational, comparative study.Methods: Forty-four adult and 47 pediatric patients with chalazia and 34 adult and 30 pediatric age- and sex-matched patients without chalazia treated at an institutional referral eye center were included. All 155 patients underwent lash sampling followed by microscopic identification and counting of Demodex mites. All 91 patients with chalazia underwent surgical removal, and among them, 74 were followed up for 18 ± 4.3 months after surgery. Statistical correlation between ocular demodicosis and chalazia and its postoperative recurrence was performed.Results: Demodicosis was significantly more (Read more...)

Medicare SGR reform gains ground, but payment plan still undecided
The American Medical Association praised what it called “strong bipartisan votes” by two Congressional committees to replace the current Medicare Sustainable Growth Rate (SGR) formula and end the “annual cycle of draconian Medicare physician payment cuts and short-term patches” on physician reimbursement.The House Ways and Means and Senate Finance committees both passed versions of the bill on Thursday, including what an AMA statement calls a plan to “consolidate and restructure existing quality improvement incentive programs to reduce the administrative and financial burden on physicians.”Action by the full House and Senate (Read more...)
CABP4 Mutations Do Not Cause Congenital Stationary Night Blindness – Corrected Proof
I read with interest the analysis of Dutch patients diagnosed with congenital stationary night blindness (CSNB) by Bijveld et al, particularly what was written regarding patients with recessive mutations in calcium binding protein 4 (CABP4; Mendelian Inheritance in Man *608965). CABP4 encodes a protein that is specifically located in photoreceptor synaptic terminals, where it probably modulates photoreceptor calcium release. Only 3 of 101 patients diagnosed with CSNB in the authors’ series had CABP4 mutations, and all 3 patients (2 families) harbored the same homozygous mutation (c.646C>T; p.Arg216X). These 3 patients had nystagmus and low vision. Two were photophobic. All 3 had (Read more...)
