In this edition of Advances in Eyecare we hear from four experts about their fields of research as applicable to optometric practice:

  • Dr Deacon Harle and Paddy Gunn discuss the use of selective laser trabeculoplasty as an alternative to topical drug management of glaucoma and ocular hypertension. They clarify what it is, how it is done and who can do it.
  • Dr Shelby Temple describes the latest technique for macular pigment assessment and the implications for its use in community practice eye health screening.
  • Dr Keyur Patel explains the use of intense pulsed light (IPL) treatment for persistent and chronic lid margin disease.

    Macular pigments absorb shorter wavelength visible light, act as anti-oxidants and reduce degenerative processes. They may also play a role in vision: specifically contrast sensitivity and glare reduction. Accurate measurement of the pigments is useful clinically as a means of assessing macular protection, especially in those susceptible to degeneration. In this interview, we speak to Dr Shelby Temple about a new macular pigment screening tool that has been recently developed at Bristol University.
