PRCIS: Health examination center-based screening provide a good supplement to clinic-based glaucoma care by detecting early-stage glaucoma, especially those with normal intraocular pressure (IOP) and less visual impairment.
PURPOSE: Opportunistic glaucoma screening for early case identification is of great value in the 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 outpatient cases in China.
MATERIALS AND METHODS: In this case-control study, 76 patients with primary glaucoma identified from a health examination center-based glaucoma screening program and 272 consecutive outpatient cases at the same hospital were enrolled from March 21 to September 30, 2016. Demographic characteristics, best-corrected visual acuity, IOP, mean deviation (MD), and pattern standard deviation (PSD) on Humphrey visual field testing in the better-seeing eye were compared between groups.
RESULTS: Screening-detected glaucoma patients had significantly lower IOP (18.3±4.2 mm Hg) than out-patient cases (26.7±12.6 mm Hg, P <0.001). Most (71.1%) of the screening-detected patients had IOP<21 mm Hg compared with 37.1% in the clinic group ( P <0.001). Seventy-five patients (98.7%) in the screening group were diagnosed as primary open angle glaucoma, compared with 44.1% in the clinic group ( P <0.001). Screening-detected patients had significantly less visual impairment than the clinic group (6.6% vs. 38.6%, P <0.05). 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, P <0.001; PSD: 6.5±3.7 dB, P <0.001).
CONCLUSION: The glaucoma screening program was effective at detecting early disease, especially normal tension glaucoma and supplemented opportunistic detection of glaucoma.
