● Tear film assessment should be undertaken with minimal invasion of the structure – non-invasive techniques should be used whenever possible ● Assessment must be made both prior to and during contact lens wear. Tear film quality should be assessed both with the lens in situ and without the lens ● Use of the Tearscope in clinical practice allows a more detailed examination of the tears to be un...

This paper addresses the problem of image-based surface reconstruction. The main contribution is the computation of the exact derivative of the reprojection error functional. This allows its rigorous minimization via gradient descent surface evolution. The main difficulty has been to correctly take into account the visibility changes that occur when the surface moves. A geometric and analytical...

A n active ciliary body controls the eye’s accommodation process, allowing near focusing to occur. The ciliary body is made up mainly of smooth muscle, known as the ciliary muscle. Accommodation occurs when the muscarinic receptors within the ciliary muscle are stimulated by the parasympathetic neurotransmitter, acetylcholine (see Part 1 Optician 29.06.12). The ciliary muscle then contracts, pu...

M acular oedema refers to the accumulation of fluid in retinal layers around the fovea, usually as a result of blood-retina barrier dysfunction. Macular oedema is not a specific entity, but rather a non-specific response to an abnormal retinal environment. Vision is impaired due to disruption of the normal cellular relationships in the retina, mechanical stress, and a mild inflammatory response...
