Purpose: To report the efficacy of inferior oblique Z-myotomy for the treatment of hypertropia in children.
Methods: Consecutive prospective analysis of all patients undergoing inferior oblique Z-myotomy for the treatment of hypertropia and inferior oblique overaction between June 2011 and June 2015 at a single tertiary centre. Pre- and post-operative hypertropia measurements were compared and analysed using the Wilcoxon signed ranks test.
Results: A total of 8 patients were included in the study. Average age at time of surgery was 7.6 years. Average hypertropia measurements in primary position improved from 8.4 prism dioptres pre-operatively to 3 prism dioptres post-operatively for distance and from 6.9 prism dioptres pre-operatively to 2 prism dioptres post-operatively for near at final follow-up (p < 0.05). Inferior oblique overaction and acquired head posture resolved post-operatively in all cases.
Conclusions: Inferior oblique Z-myectomy is a simple and effective procedure for the management of hypertropia in the paediatric population.

Purpose: Since the H1N1 Influenza Pandemic of 2009, increasing attention has been paid to the use of alcohol-based hand sanitizers. Significant research has been conducted regarding the formulation, use, and effectiveness against various types of bacteria and viruses. Adenovirus ocular infections such as Epidemic Keratoconjunctivitis, follicular conjunctivitis (EKC), and pharyngeal conjunctival fever are common ocular viral infections that present a unique challenge to the ophthalmological community because of their hardiness and lack of effective treatment options. Prior research on the use of alcohol-based hand sanitizers to combat viral strains associated with EKC has either been limited in its scope or suffered from inadequate inactivation of antivirals during the testing phase. This study evaluated the virucidal activity of Purell Hand Sanitizer against adenovirus in vitro.
Methods: Log reduction, direct incubation antiviral assays were performed with both Purell Gel Hand Sanitizer and PBS control using stocks of Adenovirus 3, 4, 5, 7a, 8, 19, and 37. Samples were inactivated and serially diluted at 10 seconds, 2 minutes, and 5 minutes and plated. Assays were done in duplicate.
Results: The hand sanitizer reached a 3-log10 decrease in viral titers at 10 seconds of exposure with adenovirus types 3, 5, 19, and 37. Two minutes of exposure was required to achieve similar results with 4 and 7a. Sufficient decrease was never achieved with type 8 despite 5 minutes of exposure.
Conclusion: Purell Gel Hand Sanitizer effectiveness is inconsistent across viral types typically associated with EKC and can potentially still be transmitted to other vectors.

Corneal opacities in infants and children pose unique management challenges. Penetrating Keratoplasty (PKP) has been used in order to clear the visual axis and prevent amblyopia, but has been historically associated with high rates of graft failure and other complications [1,2].

Leigh Syndrome is a fatal mitochondrial disease with variable ophthalmologic manifestations. Ptosis can be the initial sign in patients with this rare inherited neurometabolic disorder. Misdiagnosis of conditions including juvenile myasthenia gravis and congenital ptosis delay proper identification and palliative care. We present a noteworthy case of a 16-month-old girl with acquired progressive bilateral ptosis who was diagnosed with Leigh Syndrome after further work up suggested by our examination.

Cornea is the outermost anterior layer of the eye ball which has unique optical and physio-mechanical properties to maintain good vision. A stratified squamous epithelium is continued with the conjunctival epithelium in the limbal area and create a protective stratum on the ocular surface to defend internal structure from environmental threats . The dynamic equilibrium of the epithelial turnover is maintained by limbal niche where the Limbal Epithelial Stem Cells (LESCs) reside in an excellent arrangement.
