Title: The value of anterior segment OCT

Lecturer: Professor James Wolffsohn

Level of user: Any level

While most optical coherence tomography (OCT) instrumentation has been focused on retinal imaging, the same advantages of cross sectional imaging through biological tissue are also of importance in anterior eye imaging. For many years only time domain OCT was commercially available for anterior eye imaging, while now retinal OCTs using Fourier /spectral domain or swept source frequency domain technology have been adapted to image the anterior eye using coupling lenses in addition to a small number of dedicated anterior eye devices. Some biometry devices have also adopted OCT with deep penetration allowing simultaneous imaging from the cornea through the crystalline lens to the macular. Issues of calibration, resolution and depth penetration will be explored along with applications to better understand corneal/scleral shape, soft, RGP and scleral lens fitting, optical implant metrology, tear meniscus height, the anterior chamber angle in angle closure glaucoma and its application. Click here to book

 

Title: The value of OCT in chronic glaucoma diagnosis and monitoring

Lecturer: Professor Stepen Vernon

Level of user: Any level

Current research and practice supports the use of both retinal nerve fibre layer and macular thickness imaging in chronic glaucoma. For diagnosis, an understanding of the normal measurement ranges and in particular the influence of myopia is vital as well as recognising common artefacts. For progression detection, machine reproducibility is vital and varies with anatomical position (nasal worst). On rnfl scans, widening of an existing defect is the commonest finding when progression occurs, whereas with macular scans both may occur with research data suggesting peripapillary scans are more sensitive in early glaucoma. Click here to book

 

 

KEYNOTE LECTURE: OCT in high Myopia

Lecturer: Professor Magdy Moussa

Level of user: Any level 

Pathological Myopia is one of the most frequent causes of secondary visual disturbances worldwide. SD-OCT and recently introduced Swept source SS-OCT has revolutionized the diagnosis and management of myopic retinopathy by delineating vitreoretinal interface abnormalities. In this lecture, myopic traction maculopathy with subsequent retinoschisis and posterior retinal detachment ending by macular hole formation will be discussed in details. The role of OCT in management of such disorders (follow up , referral or surgical interference)  will be illustrated by clinical cases.  Finally, the role of OCT in management of myopic CVN will also be highlighted. Click here to book

 

Title: OCT in Diabetes

Lecturer: Mr Nigel Davies

Level of user: Any level 

This presentation will review some of the problems that are caused by macular diseases, in particular diabetes and with reference to potential differential diagnosis. The effects on vision and the OCT appearances changes that occur will be demonstrated. The underlying pathophysiology will be discussed, with examples. Current gold standard management will be reviewed so that an understanding of the disease and the process of management is obtained. Click here to book

 

Title: Integrating structure and function in glaucoma

Lecturer: Mr Nicholas Rumney

Level of user: Any level

The holy grails of glaucoma research have been i) demonstrating unequivocally that reducing IOP slows the rate of progression of vision field loss and ii) demonstrating a clear link between the functional loss of vision (visual fields) and the alteration in structure in the nerve fibre layer and optic nerve head.

The conclusion of i) was reached some years ago but ii) has remained elusive until much more recently. This presentation builds on the work of Hawerth and Hood by linking the OCT and field loss measures that define early glaucoma. Specifically tuned to the primary care optometrist whose role is to identify glaucoma cases and glaucoma suspects whilst maintaining a statistically unusually low false positive referral rate.

The presentation will demonstrate which OCT scan to use, when to use it and how to interpret it alongside making the correct choice of visual fields. The absence of OCT imaging from the 2009 NICE CG85 guidance is calling into question the proposed structures for primary and secondary care management of glaucoma. The advent of Swept-source OCT has further opened the door beyond normative database interpretation. Click here to book
