ICG TTT for retinoblastoma
Transpupillary thermotherapy (TTT) is a specific form of ocular TT using infrared radiation (diode laser). Indocyanine green (ICG) is also used to achieve the optimal phototherapy effect in eyes with minimal pigment. Twenty-one patients with 42 retinoblastomas in 30 eyes...The results of the last survey Jun21
Thank you so much again for participating in the survey. I have been asked to give several talks at regional teaching sessions about some of the issues I discuss in these articles and I am happy to continue to do...
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...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...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...
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)...
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...
OCT in peripheral corneal thinning
This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...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....
