Malcolm Long speaks with Daniela Nosch who explains her findings from a study carried out in 2011 suggesting that the presence of contact lenses does not alter the accuracy of dynamic contour tonometry measurements. She then discusses the benefits it can have for some groups of patients. 

Topics: Dynamic contour tonometry, Cornea, Goldman, GAT, IOP, Glaucoma, Ocular pulse amplitude, OPA, Intra-ocular pressure.

The pre-ocular tear film (POTF) is an important measure of the health of the surface of the eye. There are a number of pre-existing techniques for the assessment of the POTF, and one of the less well-known ones is the tear ferning test. In this interview, Helen Tilly talks to Dr Christine Purslow about tear ferning and its application in research and clinical diagnosis.

Topics: Tear film, Dry eye, POTF, Contact lens, Ocular surface, Mucous, Meniscus, Microscope, Protein, Electrolytes, Patterns, Grading scale.
