Glaucoma evidence gap map

What this map shows

At Sightsavers, our EGMs summarise, appraise, and present evidence from systematic or literature reviews.

The glaucoma EGM summarises evidence from 64 reviews. Most reviews (26) address treatment of glaucoma, followed by quality of clinical care (11). Of the remainder, nine reviews look at risk factors/prevention and another nine address case detection/screening of glaucoma, three cover quality of life, two reviews each address quality of non-clinical care and cost-benefit, one review looks at technology and one looks at epidemiology.

This gap map shows that there are clear gaps in evidence at the health-systems sector level. No reviews were identified around access to glaucoma services and cost benefit analysis.

35 reviews provide strong evidence in response to the authors’ research questions; 22 reviews show inconclusive evidence, and in seven reviews the results are weak. 33 reviews are graded low methodological quality, 17 reviews are medium quality, and 14 reviews are graded high quality.
