Prcis: Glaucomatous changes in high myopia are difficult to detect due to the similarity of functional and structural alteration in both disease. Optical coherence tomography (OCT) shows relatively high diagnostic accuracy in glaucoma with high myopia (HM).
Purpose: This study aims to evaluate the thickness differences of OCT parameters between HM and HM with glaucoma (HMG), and to verify which parameters have a higher diagnostic value on this issue according to area under the receiver operating characteristic (AUROC) curve.
Materials and methods: A comprehensive literature search was performed on PubMed, Embase, Medline, Cochrane, CNKI, and Wanfang. Eligible articles were identified by reviewing the retrieved results. The weighted mean difference and 95% CI for continuous outcomes and pooled AUROC were calculated.
Results: Fifteen studies with a total of 1304 eyes, including 569 high myopia and 735 HMG were comprised in this meta-analysis. Our results showed that, in comparison with HM, HMG had a significantly thinner thickness for retinal nerve fiber layer except for nasal sector, macular ganglion cell inner plexiform layer thickness except for superior sector and macular ganglion cell complex thickness. In contrast, the inferior sector and average thickness of retinal nerve fiber layer, macular ganglion cell complex and ganglion cell inner plexiform layer had relatively high AUROC.
Conclusion: Based on the current study of retinal OCT measurement differences between HM and HMG, ophthalmologists should pay more attention to the thinning in inferior sector and the average thickness of macular and optic disc during the management of HM.
