Abstract

The relationship between homocysteine levels and glaucoma has been questioned in previous studies without conclusive results. In the current study, we assessed the relationship between homocysteine levels and intraocular pressure which is one of the main factors in the development of glaucoma in men and women. A retrospective cross-sectional analysis of a database from a screening center in Israel which assessed 11,850 subjects, within an age range 20 to 80 years. The relationship between homocysteine and intraocular pressure has been investigated by comparing intraocular pressure in subjects with elevated and normal homocysteine and by comparing homocysteine levels in subjects with elevated and normal intraocular pressure. In addition, we compared the levels of homocysteine in subjects with and without a confirmed diagnosis of glaucoma. The mean IOP (±SD) in subjects with normal homocysteine levels(≤15mmol/L) was 13.2±2.3 mm Hg and 13.4 ±2.4 mm Hg in those with high homocysteine levels (>15 mmol/L) (P<0.008, 95% confidence interval [CI] 0.3-0.09).Nonetheless, after multivariate adjustment for age, gender, vitamin B12, and folic acid statistical significance was no longer demonstrated (P=0.37). Mean homocysteine levels (±SD) in subjects with normal intraocular pressure of≤21 mm Hg was 11.7 ±5.5mmol/L and 12.09 ± 3.43 mmol/L in those with elevated intraocular pressure (P=0.4, 95%CI 1.1-1.8). Mean homocysteine levels (±SD) in subjects with glaucoma were 11.2 ±3.5mmol/L compared to 11.7 ±5.5mmol/L in subjects without glaucoma and normal intraocular pressure≤ 21 mm Hg (P=0.4, 95% CI 1.2-2.1). The current study displays no clinical correlation between the homocysteine level and the intraocular pressure. Homocysteine may not be used as a predictive parameter to recognize those subjects prone to develop elevated intraocular pressure.
