Abstract
Purpose :
Epiretinal membrane (ERM) remains to be unknown as a potential risk factor for primary open-angle glaucoma (POAG). The purpose of this study was to compare glaucoma progression in an eye with or without ERM in the same POAG patient.
Methods :
Retrospective chart review on 179 consecutive patients with ERM and/or POAG was conducted. ERMs were grouped into 4 stages defined by Govetto et al. according to OCT images. Age, visual acuity, intraocular pressure (IOP), mean deviation (MD) on Humphry field analyzer and the number of anti-glaucoma eye drop scores were evaluated. Predominant cupping in optic disc was evaluated using fundus photograph.
Results :
Of 16 patients which met our criteria, mean age was 67.9 ± 8.5 y.o. and the number of male was 9 (56.3%). The number of eyes in each ERM stage was 1 eye in stage 1 (6.3 %), 9 eyes in stage 2 (56.3 %), 4 eyes in stage 3 (25.0 %) and 2 eyes in stage 4 (12.5 %). Mean IOP were 12.7 ± 2.0 mmHg in eyes with ERM (ERM group) and 13.4 ± 2.2 mmHg in eyes without ERM (w/o ERM group) (p=0.25). Predominant optic disc cupping in eyes with ERM compared to fellow eye, namely eyes without ERM was detected in 12 eyes (75.0 %). Fair progression between an eye with ERM and without ERM was detected in 4 eyes (25.0%). Mean MD were -12.2 ± 8.7 dB in ERM group and -6.9 ± 7.2 dB in w/o ERM group (p=0.0398). Eye drop scores was 1 in ERM group and 0 in w/o ERM group (p=0.0156)
Conclusions :
Association of ERM might potentiate to worsen glaucoma progression in eyes with POAG.
