CATARACT SURGERY AND VISUAL OUTCOMES: SINGAPORE MALAY EYE STUDY
In a population-based study of 3280 Singapore Malays aged 40–80 years (response rate 78.7%), the participants underwent a standardised interview and comprehensive ocular examination. Lavanya et al observed that 284 patients had unilateral cataract extractions (4.7%) and 154 (54%) had bilateral extractions. Older age, male sex and the presence of diabetes were significant factors associated with having had cataract surgery. Poor visual outcomes (visual acuity of 20/60 or worse) were present in 11%. Diabetic retinopathy (26%), glaucoma (17%), ARMD (15%), and posterior capsular opacification (15%) were the main causes of poor visual outcome. Under-corrected refractive errors were observed in 60% of patients with post-operative presenting visual acuity of 20/60.

DETECTION OF VISUAL-FIELD DETERIORATION BY GPA AND TNT PROGRAMMES
Diaz-Aleman et al compared the ability of Glaucoma Progression Analysis (GPA) and Threshold Noiseless Trend (TNT) programmes to detect visual-field deterioration in 42 patients with POAG followed for a minimum of 2 years. Progression was assessed subjectively by four masked glaucoma experts (gold standard) and compared with GPA and TNT results. TNT showed …
