Most visual field testing is standard automated perimetry (SAP). Field analysis in glaucoma relies primarily on the 24-2 and 30-2 patterns, as the majority of ganglion cells lie within the central 30 degrees of fixation.3 Use of 24-2 has become increasingly prevalent as the test of choice in glaucoma due to its faster testing time and reduced trial lens and lid artifact errors. For instance, if testing was performed at age 59 and, on subsequent examinations, age 60, the second test would be compared with a different database than the first test. Reis A, Vidal K, Kreuz A, et al.

It is intended to reflect ganglion cell loss and function. A comparison of visual field progression criteria of 3 major glaucoma trials in early manifest glaucoma trial patients. In 7 fields the supero-temporal defect extended to fuse with the blind spot, mimicking a superior arcuate scotoma. Even in light of 21st century technology, serial visual field testing remains the most accurate means of determining progression in glaucoma. 10 In patients with congenital and myogenic ptosis, the upper eyelid crease is often absent or subtle. It is commonly associated with orbital fat herniation, known as steatoblepharon, and drooping of the eyelids, known as blepharoptosis. Heijl A, Bengtsson B, Chauhan B, et al.
