Abstract

PURPOSE

To investigate the effects of serial intravitreal injections (IVIs) on the ocular surface and meibomian glands (MGs) in patients treated with anti-vascular endothelial growth factor (anti-VEGF) for neovascular age-related macular degeneration (nAMD).

DESIGN

Retrospective, controlled, observational study.

PARTICIPANTS

Patients with nAMD receiving unilateral IVIs with anti-VEGF agents. The fellow eye was used as control.

METHODS

Tear film and ocular surface examinations were performed on a single occasion at a minimum of 4 weeks after IVI. A pre-IVI asepsis protocol with povidone-iodine (PVP-I) was applied.

MAIN OUTCOME MEASURES

Upper and lower MG loss, tear meniscus height (TMH), bulbar redness (BR) score, noninvasive tear break-up time (NIBUT), tear film osmolarity (TOsm), Schirmer test, corneal staining, fluorescein tear film break-up time (TBUT), meibomian gland expressibility (ME), and meibum quality.

RESULTS

Ninety patients with a mean age of 77.5 years (standard deviation [SD], 8.4; range 54-95) were included. The median number of IVIs in treated eyes was 19.5 (range, 2-132). Mean MG loss in the upper eyelid was 19.1% (SD, 11.3) in treated eyes and 25.5% (SD, 14.6) in untreated fellow eyes (P = 0.001). For the lower eyelid, median MG loss was 17.4% (interquartile range [IQR], 9.4-29.9) in treated eyes and 24.5% (IQR, 14.2-35.2) in fellow eyes (P < 0.001). Mean BR was 1.32 (SD, 0.46) in treated eyes versus 1.44 (SD, 0.45) in fellow eyes (P = 0.017). Median TMH was 0.36 mm (IQR, 0.28-0.52) in treated eyes and 0.32 mm (IQR, 0.24-0.49) in fellow eyes (P = 0.02). There were no differences between treated and fellow eyes regarding NIBUT, TOsm, Schirmer test, corneal staining, fluorescein TBUT, ME, or meibum quality.

CONCLUSIONS

Repeated IVIs with anti-VEGF with preoperative PVP-I application was associated with reduced MG loss, increased tear volume, and reduced signs of inflammation compared with fellow nontreated eyes in patients with nAMD. This regimen may thus have a beneficial effect on the ocular surface.
