The primary break is usually located above the horizontal meridian – the break is connected with the detachment by a shallow peripheral sinus In 95%, the break is within 1.5 clock hours of the highest border In 93% the primary break is between 11 and 1 o’clock Total or superior detachments that cross the 12 o’clock meridian In 98% the primary break lies within 1.5 clock hours of the highest border Lincoff’s Rules Superior temporal or nasal detachments Partial or total obscuration of all vessels Obscuration of major vessels at disc margin Nasal disc margin blurring with temporal sparing Standardization of Uveitis (SUN) Nomenclature

Optic nerve abnormalities consistent with glaucoma AND visual field abnormalities in ONE hemifield and NOT within 5 degrees of fixation. Optic nerve abnormalities consistent with glaucoma but NO visual field abnormalities on any visual field test.

Note: these are all referenced to the original primary literature so that you can learn more about the derivation of each grading system. Use the navigation menu on the left side to quickly find what you need.

Nonetheless, we wanted to catalog as many systems as possible to help you communicate your findings to others. For example, diabetic retinopathy and cell / flare are almost universally accepted, while you will rarely run across formal APD measurements or dry eye grading.

Some grading systems are more popular than others. Grading in ophthalmology is an ever evolving concept.
