Abstract
Introduction: This study aimed to determine the frequency of posterior vitreous detachment (PVD) in dry and wet age-related macular degeneration (AMD) patients compared with healthy eyes via ultrawide field optical coherence tomography (UWF-OCT). Additionally, the retinal thicknesses in the central and peripheral zones of AMD patients and the control group were compared. Methods: We included 123 eyes from 83 participants with dry AMD, 123 from 87 participants with wet AMD, and 85 from 53 healthy controls. All three study groups were compared according to age, sex, best corrected visual acuity (BCVA), PVD stage, axial length, and retinal thickness in the central, perifoveal, and peripheral zones. Additional analyses included correlations between the BCVA and PVD stage and between retinal thickness and the PVD stage. Results: Complete separation of the vitreous from the macula was significantly more common in AMD patients than in the control group, as noted in 47 eyes (55.29%) in the control group, 92 eyes (74.80%) in the wet AMD group, and 93 eyes (75.61%) in the dry AMD group. The PVD stage did not significantly influence retinal thickness. BCVA in AMD patients did not correlate with the PVD stage. Conclusions: Complete PVD is more common in AMD patients than in healthy controls, as evaluated by UWF-OCT. No relationship between the PVD stage and AMD type or BCVA was observed.
