Purpose: Only a few studies have analyzed the potential link between glaucoma and cognitive function impairment. They have found controversial results. This study aims to perform quick cognitive function assessment with clock drawing test (CDT) using two different scoring systems and compare between normal tension glaucoma (NTG) and cataract patients. Methods: Totally, 30 NTG and 30 patients with cataracts were included in a prospective, pilot study. The predrawn circle was given, and patients were asked to draw the clock showing a time of 11:10. The test was evaluated using two methods – Freund method using a 7-point scoring scale (optimal cutoff ≤4) and Rakusa using a 4-point scoring scale (optimal cutoff ≤3). The level of significance was set at P < 0.05. Results: CDT result was significantly better in cataract group than in NTG group: 3.5 (2) versus 2 (2) by Freund, (P = 0.003) and 6.5 (1) versus 4.5 (2.75) by Rakusa, respectively (P = 0.004). Sixty percent (n = 18) of NTG group and 10% (n = 3) of cataract group patients completed the CDT in the specific picture manner (the short hand on 11 and the long hand between 11 and 12), (P = 0.001). Conclusions: Lower CDT results were seen in NTG patients according to two different scoring systems. NTG patients showed a specific manner of drawing. Further prospective studies are needed to investigate the CDT reliability as fast screening test of cognitive function impairment in glaucoma patients.
