Indian Journal of Clinical and Experimental Ophthalmology (IJCEO) is open access, a peer-reviewed medical journal, published quarterly, online, and in print, by the Innovative Education and Scientific Research Foundation (IESRF) since 2015. To fulfil our aim of rapid dissemination of knowledge, we publish articles ‘Ahead of Print’ on acceptance. In addition, the journal allows free access (Open Access) to its content, which is likely to attract more readers and citations of articles published in IJCEO.

Abstract
Aim: Aim of this study was to investigate for a relationship between pupillary oscillations (PO) and blinking rate (B) in various vision deprived states such as in refractive errors (Myopes).
Materials and Methods: A case control descriptive study with 340 individuals, including 220 myopes and 120 emmetropes were compared for pupillary oscillation rate (PO), blinking rate (B) and Pupillary oscillation/blinking rate (PO/B) ratio bilaterally in normal as well as in individual subgroups of decreasing visual acuity, done under slit lamp in dim diffuse illumination.
Results: The pupillary oscillation rate (PO) was 49.23± 8.80 in right eye (POR) and 56.44 ±8.95 in left eye (POL) in the control group whereas it was 46.28 ±11.55 and 52.79 ±11.22 in the right and left eyes respectively of the cases. While PO/B ratio was 12.41±14.11 in the right eye and 14.33±15.9 in the left eye in control group, it was 7.13 ± 7.86 in the right and 8.18 ±9.07 in the left eye of the cases respectively. The blinking rate (B) was 8.62 ±6.06 in the control eyes and in the cases it was 11.69 ±7.91. The comparative analysis of all of the above parameters were statistically significant with p < 0 xss=removed> POL in 7.50% and POR < POL>
Conclusion: This study could be useful in non-verbal patients and comatose patients as diagnostic and prognostic tool, having an implication in different refractive errors and neurological diseases.
Keywords: Blinking rate (B), Pupillary oscillations (PO), Refractive errors.
