5th Year Research Project
As part of their 5th year research project, UNSW Optometry and Vision Science students Sheila Lam and Clarissa Lin conducted a study with CFEH researchers Henrietta Wang, Jack Phu, Michael Kalloniatis and A/Prof Sieu Khuu (UNSW) to evaluate a new computer-based test, the Line Sag test, for assessing metamorphopsia in patients with epiretinal membranes.
The Line Sag test was designed to address the current pitfalls of the Amsler grid such as the perceptual filling-in effect and unstable fixation which affect its sensitivity in detecting distortions.
This study concluded the Line Sag test was able to detect more cases of metamorphopsia, particularly in asymptomatic patients.
