Tribal Odisha Eye Disease Study # 4: Accuracy and utility of photorefraction for refractive error correction in tribal Odisha (India) school screening.

Purpose: To compare the photorefraction system (Welch Allyn Spot™) performance with subjective refraction in school sight program in one Odisha (India) tribal district.

Methods: In a cross-sectional study school students, aged 5-15 years, referred after the preliminary screening by trained school teachers received photoscreening and subjective correction. The photoscreener was compared to subjective refraction in the range of +2D to -7.

Synthesis of a bile acid-based click-macrocycle and its application in selective recognition of chloride ion.

A novel method for the synthesis of a bile acid-based macrocycle has been developed using click chemistry. The 1,2,3-triazolium derivative of the macrocycle shows remarkable selectivity in binding of chloride ion.

Predictors of normal optic nerve head, retinal nerve fiber layer, and macular parameters measured by spectral domain optical coherence tomography.

Purpose: To evaluate the effects of signal strength, age, sex, optic disc size, and axial length on the normal optic nerve head (ONH), retinal nerve fiber layer (RNFL), and macular measurements with spectral domain optical coherence tomography (SD-OCT).

Methods: In an observational, cross-sectional study, 119 eyes of 60 normal subjects of Indian origin underwent ONH, RNFL, and macular imaging with SD-OCT during the same visit. Linear mixed-modeling methods were used to evaluate the effects of signal strength, age, sex, optic disc area, and axial length on ONH, RNFL, and macular measurements.

Evaluation of central corneal thickness measurement with RTVue spectral domain optical coherence tomography in normal subjects.

Purpose: To determine (1) repeatability of central corneal thickness (CCT) measurements by spectral domain optical coherence tomography (RTVue; Optovue, Inc, Fremont, CA) and (2) agreement between CCT measurements by RTVue and those by ultrasonic pachymetry, Orbscan, and anterior segment optical coherence tomography (ASOCT).

Methods: In a prospective observational study, 2 cohorts of normal subjects were recruited. In the first cohort (51 subjects), 5 measurements of CCT were obtained by RTVue during the same visit to determine the repeatability.

Synthesis of click bile acid polymers and their application in stabilization of silver nanoparticles showing iodide sensing property.

A novel method for the synthesis of bile-acid-based polymers has been developed using click chemistry. These 1,2,3-triazole-containing polymers have been found to stabilize silver nanoparticles that show selective colorimetric sensing for iodide ion.

Anion recognition by 1,2,3-triazolium receptors: application of click chemistry in anion recognition.

Cyclic and acyclic bile acid-based 1,2,3-triazolium receptors which show remarkable ability to recognize anions through C-H...
