Emerging developments in dry eye
An estimated 344 million people worldwide suffer from dry eye [1]. This chronic syndrome is characterised by a vicious cycle of tear film hyperosmolarity, tear instability and corneal stress, leading to increased friction, inflammation, ocular surface damage and decreased visual...
Essentials of OCT in Ocular Disease
Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...
High myopia macular thickness
The purpose of this study was to compare macular thickness and volume in 15 highly myopic (>-6D) young children with 11 age-matched controls (-2 to +4D refractive errors) using Stratus third generation OCT. Mean spherical equivalent was -9.42 ±2.81D for...
A comparison of colour vision tests in the presence of contrast sensitivity loss
This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...
Managing orbital compartment syndrome
This experimental study using cadaveric models was done to evaluate the surgical technique effective in relieving orbital compartment syndrome. Twelve cadaveric orbits were injected with blood analogue stained with fluorescein. Pressure probes were inserted in superotemporal (advanced 40mm into orbit)...
Lucentis for pseudophakic CMO
Pseudophakic cystoid macular oedema (CMO) develops angiographically in up to 20-30% after uneventful phacoemulsification. This study aimed to evaluate the potential efficacy and safety of intravitreal ranibizumab in patients with pseudophakic CMO after cataract surgery. Seven eyes were included in...The management of watery eye in an infant with facial dysmorphism
A six-month-old child with facial dysmorphism is brought to the eye clinic with history of watery right eye since birth. How will you manage this child? Causes for watery eye in an infant 1. Overproduction of tears a. Infections b....Pioneering professor performs 30,000th laser eye procedure
A Moorfields Eye Hospital NHS Foundation Trust and Moorfields Private Hospital consultant has performed his 30,000th refractive laser eye procedure (at Moorfields Private), 36 years after he carried out the first of its kind in the UK. In 1989, while...Portable corneal topography – exploration of a prototype
Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...
