ABSTRACT

Glaucoma is an optic neuropathy characterized by the loss of retinal ganglion cells and their axons. Two cases are presented, both myopic and with suspected glaucoma, with the purpose of assessing the role of ganglion cell analysis in their diagnosis. Evaluation of structural glaucomatous changes in myopic eyes is a difficult task, due to the considerable morphological variations occurring in the optic nerve head and other structures from the posterior segment of the eye. Optical coherence tomography allows in vivo quantitative analysis of the optic disc, the retinal nerve fiber layer, and the macular area, but interpreting the findings in myopic eyes, particularly in highly myopic eyes, may be a real challenge. Recent studies have shown that macular measurements have advantages over retinal nerve fiber layer analysis to determine whether the retinal thickness defects are related to glaucoma or to myopia. However, several studies should be considered in the attempt to reach an accurate diagnosis.
