Purpose: To identify risk factors for late presentation in chronic glaucoma. Materials and Methods: In a hospital‑based case–control study, 312 newly diagnosed consecutive patients with chronic glaucoma were recruited to study in Nikookari Hospital in Tabriz – Iran. Cases were defined as patients presenting with absolute field loss within 5° of fixation or a cup to disc ratio >0.8 in one or both eyes (188 patients). Controls were patients with no absolute field loss within 20° in either eye but otherwise glaucomatous field loss and a cup to disc ratio >0.5 or a difference of 0.2 or greater between the discs (124 patents). Results: In logistic regression model, there was a significant association between late presentation and male gender, lower education status, pseudoexfoliative glaucoma, high intraocular pressure (IOP) in the first presentation and no eye exam in last 2 years. Patients with pseudoexfoliative glaucoma had 1.5 times more odd for late presentation (1.52 confidence interval [CI]: 1.14–2.24 P = 0.004). Patients that visited by an ophthalmologist in the last 2 years had 0.5 less likely to present with advanced glaucoma (0.54 CI: 0.32–0.92 P = 0.025). Higher IOP in initial examination was associated with advanced glaucoma. We estimated 1.08 increase in odd (CI: 1.03–1.04 P = 0.001) per increase in 1 mmHg in IOPs above 25 mmHg. Conclusion: Our study shows that several risk factors present for late presentation in chronic glaucoma. Our results suggest planning screening programs in high‑risk individuals for early detection of glaucoma and prevention of blindness.
