Abstract
In this paper, we examine the consequences of data breaches for a breached company. We find the economic consequences are, on average, very small for breathed companies. On average, breaches result in less than -0.3 percent cumulative abnormal returns in the short window around the breach disclosure. Except for a few catastrophic breaches, the nominal difference in cumulative abnormal returns between breach companies and the matched companies disappears within days after the breach. We also test whether data breaches affect future accounting measures of performance, audit and other fees, and future Sarbanes-Oxley Section 404 reports of material internal control weaknesses, but find no differences between breach and matched companies. Our results address the question why companies are not spending more to reduce breaches. We conclude by providing a few explanations of why there appears to be an effect at the economy-wide level, but no noticeable effect on individual company performance.

Abstract
Purpose: The cornea is the most significant refractive medium in the eye. Pathologies affecting the cornea usually have a great impact on vision. The etiology of corneal disorder varies from one geographical location to another. The objective of this study was to determine the pattern of corneal disorders at Ekiti State University Teaching Hospital, Ado-Ekiti. Materials and Methods: A retrospective study of case records of patients with cornea disorders over a 5-year period was carried out. Demographic characteristics, presenting visual acuity, and risk factor for cornea disorders were retrieved. Data were entered into the Statistical Package for the Social Sciences version 20, and statistical significance was inferred at P < 0.05. Results: Corneal disorders accounted for 3.3% of the eye disorders seen during the period of study. The median age was 37 years. Males outnumbered females giving a ratio of 1.9:1 and the age range from 0.25 to 92 years. There were more females than males in the 11-20 years' age group. Students (84, 25.4%) and artisans (62, 18.8%) were the two leading occupational groups. Infectious cases constituted 27.2% of the cases. Visual acuity at presentation was <3/60 in 131 (39.7%) cases. Foreign body entry was the leading etiologic agent in 101 (30.6%) cases. Conclusion: Half of the patients were blind at presentation, and many of them presented after more than 1 week of the onset of symptoms. Corneal foreign body, trauma, and vernal keratoconjunctivitis were the leading known predisposing factors. There will be need to emphasize more on the role of protective eye devices among our people, especially those who engage in outdoor activities.
