Evidence of a Hardening in the Cosmic Ray Proton Spectrum at around 166 TeV Observed by the GRAPES-3 Experiment.

We present the measurement of the cosmic ray proton spectrum from 50 TeV to 1.3 PeV using 7.81×10^{6} extensive air shower events recorded by the ground-based GRAPES-3 experiment between 1 January 2014 and 26 October 2015 with a live time of 460 day.

Comparison of pupil size in patients of migraine with photophobia versus normal subjects and correlation of the pupil size to severity of headache.

Purpose: To compare the pupil size of patients having migraine with photophobia versus normal subjects and to correlate the pupil size to the severity of headache.

Methods: This was a prospective case-control study. One hundred eyes of 50 patients who had migraine with photophobia were compared with same number of control subjects who had no history of headache.

Binocular Function in Subjects with Orthotropic Duane Retraction Syndrome.

: The aim of this study is to evaluate binocular vision parameters such as near point of accommodation (NPA), near point of convergence (NPC), fusional vergence ranges in subjects with orthotropic Duane retraction syndrome (DRS) and to compare with normal age-matched controls : A total of 24 subjects (14 Type 1, 2 Type 2, 8 Type 3 DRS) who were diagnosed to have DRS and 15 normals were included in the study. The following binocular vision parameters were assessed in all subjects: amount of the deviation (for near and distance in all gazes), NPC, NPA, positive and negative fusional vergence (PFV and NFV) reserve and stereopsis. : Accommodative amplitude was normal in subject with DRS (median (95% confidence interval (CI):15D (11.

Outcomes of Frontalis Sling Versus Levator Resection in Patients With Monocular Elevation Deficiency Associated Ptosis.

Purpose: To compare outcomes of frontalis sling (FS) silicone and levator resection (LR) in ptosis associated with monocular elevation deficiency.

Methods: Retrospective interventional comparative case series of FS and LR in monocular elevation deficiency associated ptosis. Favorable outcome was defined as difference in margin reflex distance 1 of ≤1 mm between the 2 eyes in unilateral cases and margin reflex distance 1 of 4 mm in bilateral cases at last follow-up visit.

A simple and novel grading method for retraction and overshoot in Duane retraction syndrome.

Strabismus in Duane retraction syndrome is frequently associated with significant globe retraction and overshoots. However, there is no method to objectively grade retraction and overshoot. Our purpose is to describe a novel objective grading method.
