Abstract

Health examination center-based screening provide good supplement to clinic-based glaucoma care by detecting early stage glaucoma, especially those with normal intraocular pressure and less visual impairment.Opportunistic glaucoma screening for early cases identification is of great value in prevention of severe visual impairment, however, novel, low-cost models are needed. We aimed to determine whether health examination center-based glaucoma screening identifies diseases earlier than out-patient cases in China.In this case control study, 76 patients with primary glaucoma identified from a health examination center-based glaucoma screening program and 272 consecutive out-patient cases at the same hospital were enrolled from March 21 to September 30, 2016. Demographic characteristics, best-corrected visual acuity, intraocular pressure (IOP), mean deviation (MD) and pattern standard deviation (PSD) on Humphrey visual field testing in the better-seeing eye were compared between groups.Screening-detected glaucoma patients had significantly lower IOP (18.3±4.2 mmHg) than out-patient cases (26.7±12.6 mmHg, P0.001). Most (71.1%) of the screening-detected patients had IOP21 mmHg compared to 37.1% in the clinic group (P0.001). Seventy-five patients (98.7%) in screening group were diagnosed as primary open angle glaucoma, compared to 44.1% in the clinic group (P0.001). Screening-detected patients had significantly less visual impairment than the clinic group (6.6% vs. 38.6%, P0.05). Mean MD (-4.4±5.0 dB) and PSD (4.4±3.6 dB) for the screening group were superior to the clinic group (MD:-16.5±10.5 dB, P0.001; PSD: 6.5±3.7 dB, P0.001).The glaucoma screening program was effective at detecting early disease, especially normal tension glaucoma and supplemented opportunistic detection of glaucoma.
