The Achievement of IOP Target Among a Sample of Iraqi Patients with Glaucoma: A Retrospective Study.

ABSTRACT

Background: Glaucoma is a chronic progressive eye disorder. It is the primary cause of blindness. To prevent glaucomatous damage and blindness, the intra-ocular pressure (IOP) must be lowered to certain levels, this level is known as "IOP" target. Many studies conducted in developed countries have found that the majority of glaucoma patients failed to reach their target IOP. Purpose: This study aimed to assess the achievement of IOP target among Iraqi patients with glaucoma and to determine the factors affecting it. Patients and Methods: A single-center retrospective cohort study was conducted by inspecting the records of all patients with confirmed cases of glaucoma who were admitted to the Ibn-Al-Haitham Hospital outpatient unit from January 2020 to December 2022. To be included in the study, the patient must be newly diagnosed with glaucoma. In addition, full information on the patient's demographics, medical therapy used, and IOP at baseline and after 1 month of treatment must be available in the patient's case sheet. After considering the study inclusion criteria, the records of 760 patients were excluded, and only 100 patients were eligible. Results: The included patients were mostly males, with an average age of 57.86 years. A 70% of the patients had elevated IOP in both eyes. Most patients (38%) were treated with two anti-glaucoma drugs. Only 35% of the patients achieved their targeted IOP. Regarding the factors influencing the achievement of the IOP target, all demographic data (age and gender) had a non-significant effect, while the number of prescribed drugs affected the ability of the patient to reach the IOP target. Conclusion: Most of Iraqi glaucomatous patients do not achieve their IOP target. The number of prescribed eye drops can significantly affect the ability of glaucoma patients to reach their targeted IOP.
