Introduction Mental health is a significant concern for patients diagnosed with glaucoma, as visual impairment can have a profound impact on psychological well-being. Conversely, psychological vulnerability in glaucoma patients can negatively influence treatment adherence to ocular hypotensive therapy, thereby potentially exacerbating disease progression in a vicious cycle. The study protocol proposed herein aims to explore the impact of psychological states such as anxiety, depression, and stress on both medication adherence and progression of glaucoma. Materials and methods This study is to be a prospective multicenter study conducted at four tertiary medical centers. Patients recently diagnosed with glaucoma and not yet treated will be enrolled. Anxiety, depression, and stress scales will be administered at baseline, one year, and two years, along with glaucomatous assessments to be performed every six months. Validated questionnaires (Generalized Anxiety Disorder Assessment [GAD-7], Patient Health Questionnaire [PHQ-9], and Perceived Stress Scale-10 [PSS-10]) will assess anxiety, depression, and stress, respectively. The primary objective is to correlate post-diagnosis psychological status with medication adherence and disease progression. The effects of pre- and post-diagnosis changes in anxiety, depression, and stress on disease progression will be analyzed. Kaplan-Meier survival analysis and logistic regression will be performed to identify clinical characteristics associated with increased risk of developing anxiety, depression, and stress in glaucoma patients.
