Opthamologist News:

I gave up on heroes a long time ago, but I still believe in prophets -- people who have a vision of what needs to be told, and the words and the imagination and the guile to tell it. Here in Minnesota, Bruce Kramer was that kind of person. While social media glowed white hot with icy cold videos of the "ALS Bucket Challenge", Bruce was on year number four of his personal amyotrophic lateral sclerosis challenge: to work through the "dis ease" that the disease brought to his life. Bruce died last Monday like most prophets do -- early. Either we kill them off to shut them up, or they suffocate under the weight of all the troubles borne on our behalf; or, as in Bruce's case, they die of the disease that gave them the prophet's vision. As master communicator, accomplished musician, and dean...

Conclusions The vast majority of patients with RWs will be admitted in a stable condition and haemodynamic instability was almost exclusively seen in the anterior thorax. The most common site was the posterior abdomen. Detailed imagining should be used liberally in stable patients and unplanned extraction in an uncontrolled environment should be strongly discouraged.

Publication date: 25 July 2015 Source:Journal of Alloys and Compounds, Volume 638 Author(s): R.S. Ajimsha , Amit K. Das , P. Misra , M.P. Joshi , L.M. Kukreja , R. Kumar , T.K. Sharma , S.M. Oak We have grown Ga doped ZnO (GZO) thin films at moderate temperatures with Ga concentrations in the range varying from 0.25 to 3at.% on sapphire substrates using buffer assisted pulsed laser deposition. Room temperature resistivity measured was ∼5.1×10−5 Ωcm with a electron mobility of ∼41.9cm2/Vs for an optimum Ga concentration of ∼0.75at.% in the GZO films. Buffer assisted growth methodology maintains relatively good crystalline quality of the GZO thin films, thereby improving the electron mobility even at high dopant concentrations. This plays a key role in decreasing the resistivity ...

The thickness of the Ni buffer layer was varied between 2 and 5nm. As-deposited GZO films that contained the PC substrate show an average optical transmittance of 81.3% in the visible wavelength region and an electrical resistivity of 3.1×10−3 Ωcm, while GZO/Ni bi-layered films show different opti...

Yakuphanoglu Thin film of CuNiO2 was prepared by sol gel method to fabricate a photodiode. The surface morphology of the CuNiO2 thin film was investigated by atomic force microscopy (AFM). AFM results indicated that CuNiO2 film was formed from the nanoparticles and the average size of the nanoparticles was about 115nm. The optical band gap of CuNiO2 film was calculated using optical data and was found to be about 2.4eV. A photodiode having a structure of Al/p-Si/CuNiO2/Al was prepared. The electronic parameters such as ideality factor and barrier height of the diode were determined and were obtained to be 8.23 and 0.82e...

Conclusion. Segmental stability decreases with the number of instrumented segments regardless of the used implant. Comparing the different fixation techniques biomechanically, the locking plate and cage construct was stiffer in all test modes than the anchored devices in multilevel constructs. However, it remains unclear what the clinical significance may be. Level of Evidence: N/A (Source: Spine)

Abstract Congenital glaucoma differs from adult glaucoma in that it represents a panocular disorder defined by structural, functional, and physiologic parameters. In order to achieve excellent visual outcomes, the management of congenital glaucoma involves concurrently controlling intraocular pressure and treating amblyopia, while minimizing any influence of a compromised visual axis. Thus far, difficulty in assessing visual function in pre-verbal children has resulted in a paucity of long-term visual outcome data. However, based on commonly recognized obstacles to structural/physiologic stability and functional rehabilitation status, we propose a congenital glaucoma severity scale in order to provide a cross-sectional stratification of disease severity. As the severity of patholo...

Conclusions: A group of optometrists and academics new to implementing education in EBP displayed positive attitudes to EBP but considered that its application and teaching could be significantly hindered by a lack of time to access and appraise the large volume of available research evidence in the field of eye care.

Conclusions: Biofilms of the emerging pathogen A. xylosoxidans were more resistant to the disinfectants PAPB and BAK than biofilms of P. aeruginosa. Because of the emergence of A. xylosoxidans and the demonstrated greater resistance to the common ophthalmic preservatives BAK and PAPB than the standard Gram-negative organism P. aeruginosa, A. xylosoxidans biofilms should be assessed in antimicrobial challenge tests to assure the safety of multiuse ophthalmic products.

Conclusions: Reduction in equivalent intrinsic blur was greater than the reduction in optical blur after AO correction of wavefront error. This finding implies that visual acuity in subjects with high equivalent intrinsic blur can be improved beyond that expected from the reduction in optical blur alone.

Conclusions: The DESD Reading Test and Spelling Scale had significant correlations with the WRAT-3 Spelling subtest and GORT-4. However, the small correlation between the DESD Reading Test and the WRAT-3 Word Reading subtest indicates that some caution should be used when interpreting the results of the DESD Reading Test. Therefore, practitioners may find the DESD Spelling Scale to be a more useful tool in identifying children who may have reading difficulties. (Source: Optometry and Vision Science)

Conclusions: The Waggoner CCVT is an adequate color vision screening test with several advantages and appears to provide a fairly accurate diagnosis of deficiency type. Used in conjunction with other color vision tests, it may be a useful addition to a color vision test battery. (Source: Optometry and Vision Science)

Conclusions: Heavy alcohol consumption significantly increased the risk of age-related cataract, whereas moderate consumption may be protective for this ocular condition. Clinically, information on a patient’s alcohol drinking history might be valuable to general physicians and ophthalmologists when there is a diagnosis of age-related cataract and should be collected on a routine basis in eye clinics.
