Editor’s Note When a school-aged male child experiences a decline in vision in both eyes, and after excluding refractive diseases, visual function issues, glaucoma, and other conditions, if the fundus shows no abnormalities, yet OCT indicates a lattice-like change in the temporal side of the macular nerve epithelium, and VEP shows a slight decrease in … Read more
This study aims to use frequency-domain OCT (FD-OCT) to assess the changes in GCC thickness and RNFL thickness in patients with AION, exploring the sensitivity of both metrics in evaluating AION severity. [Clinical Research] Assessment of GCC and RNFL Thickness in AION Diagnosis Hu Liying Li Zhiqing Li Xiaorong 300384 Tianjin Medical University Eye Hospital … Read more
Abstract Objective To explore the significance of detecting the thickness of the ganglion cell complex (GCC) in the macular region for diagnosing patients with preperimetric glaucoma (PPG). A self-controlled study and case-control study design were employed. The study subjects included 20 patients with primary open-angle glaucoma (POAG) (20 eyes without visual field defects in the … Read more
The Significance of GCC and GCA Examination The structure parameters of the Circumpapillary retinal nerve fiber layer (cpRNFL) and the optic nerve have always been important detection indicators for OCT in the application of glaucoma diseases. However, due to the large range of optic nerve cup-to-disc ratio, changes in the vascular structure of the … Read more

☞ Different reflective signals of normal retinal tissue in OCT: 1. The nerve fiber layer and the retinal pigment epithelium exhibit high reflectivity. 2. The plexiform layer and nuclear layer show moderate reflectivity. 3. Photoreceptor cells have low reflectivity. ☞ Normal retinal thickness: 1. The distance from the vitreoretinal interface to the anterior surface of … Read more
