AIM: To evaluate the relationship between damages of visual field and retinal nerve fiber layer (RNFL) thickness in primary open angle glaucoma (POAG) with highly myopia. POAG with highly myopia group (21 eyes of 17 cases), POAG with non-highly myopia group (17 eyes of 16 cases), highly myopia without POAG group (25 eyes of 20 cases) and normal control group (19 eyes of 17 cases). METHODS: The static central visual fields were tested by Humphrey 750 automated perimeter and thickness of RNFL was measured by optical coherent tomography (OCT). Main outcome mean deviation (MD), pattern standard deviation (PSD) and mean sensitivity at superior, inferior, nasal and temporal sectors in total deviation probability plots. Thickness of RNFL at superior, inferior, nasal and temporal sector. RESULTS: There were more obvious general depression of sensitivity in total deviation probability plots of the early POAG with highly myopia than that of POAG without highly myopia, and the early visual field defects of glaucoma in pattern deviation probability plots of this group. MD of POAG with highly myopia was more than those of others (P < 0.05). The differences of MD, PSD and mean sensitivity between POAG with highly myopia and others were significant (P < 0.05). Mean sensitivities in each sector of POAG without highly myopia were similar to those of highly myopia (P> 0.05). The thickness of RNFL of POAG with highly myopia was thinner than that of others and the thickness of RNFL of normality was thicker than that of others. The relationship between mean sensitivity and the thickness of RNFL in each quadrant was significant (P < 0.05). CONCLUSION: Pattern deviation probability plots is an important favor for judgment of the visual field changes in POAG with highly myopia. The relationship between RNFL thickness by OCT and visual field damage may provide clinically relevant information in diagnosis of POAG with highly myopia.
