Abstract

The macula region bears the highest density of retinal ganglion cells (RGC).¹ Macula damage is seen early in glaucoma using the ganglion cell complex (mGCC or mGCL++) of the Optical Coherence Tomography (OCT).² Standard Automated Perimetry (SAP) is an integral tool in glaucoma diagnosis and management in our local clinics. On SAP, this macula region falls within 10 degrees from fixation. This area is better tested using the 10-2 visual field (VF) tests than the 24-2 VF test because the former tests 68 points while the latter tests only 4 points within this 10 degrees.³ Early structural macula defects detected by OCT may correspond to functional defects detected using the 10-2 test. The aim of this study is to investigate the correlation of structure to function in glaucoma evaluation, if any, in order to improve timely glaucoma diagnostic ability among African descents.
