Efron Gradings….@ APOC Singapore 2011

Professor Nathan Efron

It’s an exciting experience to be able to attend Professor Efron’s lecture in APOC. I have really learned a lot as well as further understood the usage of Efron Gradings that has been so important. Hope to share something I learned to all.


Nathan Efron completed his BScOptom & PhD at the University of Melbourne in 1981, & after two years of post-doctoral studies in Berkeley, USA & Sydney, he returned to Melbourne as lecturer then senior lecturer responsible for contact lens education. In 1990 he took up the foundation Chair of Clinical Optometry at the University of Manchester, England, and established a contact lens research & consultancy unit known as Eurolens Research.

In Manchester, he served as Head of Department from 1992-97 & Dean of Research for the university from 2001-04, & was admitted to the degree of Doctor of Science in 1995. Professor Efron returned to Australia in 2006 & joined the Institute of Health & Biomedical Innovation in the School od Optometry at the Queensland University of Technology (QUT), as Research Professor. He has served as President of both the Cornea & Contact Lens Society of Australia (1981) & the British Contact Lens Association (1997).

He lectures extensively, particularly in the field of the ocular response to contact lens wear, and has published over 700 scientific papers, abstracts & textbook chapters, and has written/edited 12 books. Professor Efron has won a number of prestigious international awards in the UK, Germany & the US.

The Efron Grading Scales provide a standard clinical reference for describing the severity of contact lens complications. Professor Nathan Efron, international lecturer in the field of the ocular response to contact lens wear and author of over 500 scientific works, developed the unique scales. They provide practitioners with a simple method of ocular condition grading, against which any future tissue change may be assessed and therefore enabling choices as to the best course of action.

The 16 sets of grading images cover the key anterior ocular complications of contact lens wear. The conditions are illustrated in five stages of increasing severity from 0 to 4, with ‘traffic light’ colour banding from green (normal) to red (severe) – providing a simple and convenient aid for the optical professional.

Glaucoma… Steals your Vision…. No Warning


Glaucoma is an eye disorder in which the optic nerve suffers damage, permanently damaging vision in the affected eye(s) and progressing to complete blindness if untreated. Optic nerve is the part of the eye that carries images we see from the eye to the brain. The optic nerve is made up of many nerve fibres (like an electric cable containing numerous wires).

It is often, but not always, associated with increased pressure of the fluid in the eye (aqueous humour). The term ‘ocular hypertension’ is used for cases having constantly raised intraocular pressure (IOP) without any associated optic nerve damage. Conversely, the term ‘normal’ or ‘low tension glaucoma’ is suggested for the typical visual field defects when associated with a normal or low IOP.Glaucoma damages nerve fibres, which can cause blind spots in our vision and vision loss will develop.

The nerve damage involves loss of retinal ganglion cells in a characteristic pattern. There are many different subtypes of glaucoma, but they can all be considered a type of optic neuropathy. Raised intraocular pressure is a significant risk factor for developing glaucoma (above 21 mmHg or 2.8 kPa). One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressure for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

Glaucoma can be divided roughly into two main categories,”open angle” and “closed angle” glaucoma. Closed angle glaucoma can appear suddenly and is often painful; visual loss can progress quickly, but the discomfort often leads patients to seek medical attention before permanent damage occurs. Open angle, chronic glaucoma tends to progress at a slower rate and patients may not notice they have lost vision until the disease has progressed significantly.

Signs and tests

A test called Tonometry is done to check eye pressure. However, eye pressure always changes. Eye pressure can be normal in some people with glaucoma. This is called normal-tension glaucoma. Your doctor will need to run other tests to confirm glaucoma.

Some of the tests your Opthalmologist may perform can include:

  • Using a special lens to look at the eye (gonioscopy)
  • Photographs or laser scanning images of the inside of the eye (optic nerve imaging)
  • Examination of the retina in the back of the eye
  • Slit lamp examination
  • Visual acuity
  • Visual field measurement


The goal of treatment is to reduce eye pressure. Treatment depends on the type of glaucoma that you have.

If you have open-angle glaucoma, you will probably be given eye drops. You may need more than one type. Most people can be treated successfully with eye drops. Most of the eye drops used today have fewer side effects than those used in the past. You may also be given pills to lower pressure in the eye.

Other treatments may involve:

  • Laser therapy called an iridotomy
  • Eye surgery if other treatments do not work

Acute angle-closure attack is a medical emergency. Blindness will occur in a few days if it is not treated. If you have angle-closure glaucoma, you will receive:

  • Eye drops
  • Medicines to lower eye pressure, given by mouth and through a vein (by IV)

Some people also need an emergency operation, called an iridotomy. This procedure uses a laser to open a new pathway in the colored part of the eye. This relieves pressure and prevents another attack.

Congenital glaucoma is almost always treated with surgery. This is done using general anesthesia. This means the patient is asleep and feels no pain.

If you have secondary glaucoma, treatment of the underlying disease may help your symptoms go away. Other treatments may be needed.
