Brief Summary
This study aimed to examine the effect of Tiotropium, which is used in the treatment of COPD, on eye symptoms.The study was conducted prospectively. Patients were examined in three groups. Thirty-six patients were included in each group in the study. Anterior chamber parameters, intraocular pressure values, and photopic-mesopic pupil diameters were measured at the initial visit for Group 1 and Group 2 patients, and at the third month of treatment for Group 3 patients.

Outcome Measures
Primary Outcomes (1)
Tiotropium causes narrowing of the eye angles and an increase in intraocular pressure and pupil diameters.
Tiotropium 18 mcg is a long-acting anticholinergic drug used in the treatment of COPD. In patients diagnosed with COPD who do not receive any steroid treatment and who are not diagnosed with hypertension, glaucoma, diabetes mellitus, cataract and who have not undergone eye surgery and using only handhaler Tiotropium 18 microgram, a narrowing of the eye angles, an increase in photopic-mesopic pupil diameters and intraocular pressure were detected in the third month of treatment.
Measurements were made in the third month of Tiotropium treatment.
Secondary Outcomes (1)
Tiotropium did not cause acute angle-closure glaucoma in COPD patients.
Measurements were made in the third month of Tiotropium treatment.
Study Arms (3)
Group 1
Group 1 consisted of COPD patients not receiving any treatment ( inhaled and/or systemic steroids, long-acting inhaled beta-2 agonists alone, theophylline and combined long-acting beta-2 agonists and long-acting anticholinergic ). These patients are early stage COPD patients.
Group 2
Group 2 consisted of healthy volunteers for similar age and gender.
Group 3
Group 3 consisted of COPD patients of the same age and gender with receiving only handhaler Tiotropium 18 mcg for three months.
Interventions
Tiotropium is a long-acting anticholinergic agent and has a bronchodilator effect. According to the COPD Gold 2024 guideline, it is one of the long-acting bronchodilator drugs used as the first choice in the treatment of group A COPD patients.
Eligibility Criteria
Three groups were formed for the study. Group 1 consisted of COPD patients not receiving treatment, Group 2 consisted of healthy volunteers for similar age and gender, and Group 3 consisted of COPD patients of the same age and gender with receiving handhaler Tiotropium 18 mcg. Anterior chamber parameters, intraocular pressure values and photopic-mesopic pupil diameters were measured at the initial visit for Group 1 and Group 2 patients, and at the third month of treatment for Group 3 patients.
