PURPOSE: To investigate the relationships between preoperative factors and intraocular pressure (IOP) reduction after phacoemulsification in normal, open-angle glaucoma (OAG) and angle-closure glaucoma (ACG) patients. METHODS: IOP was measured before and 3 months after cataract surgery in 30 normal, 24 OAG and 31 ACG patients. The relationship between IOP reduction after cataract surgery and preoperative parameters including anterior chamber depth (ACD), axial length (AL), preoperative IOP/ACD ratio (PD ratio), preoperative IOP/AL ratio (PL ratio) were investigated in the 3 groups. RESULTS: Significant IOP reduction was observed in all 3 groups after surgery (paired sample t-test; p < 0.05), and IOP reduction was correlated with preoperative IOP level in all 3 groups (Pearson's correlation; p < 0.05). Other preoperative parameters such as ACD and AL were not correlated with IOP reduction, and PD ratio was significantly correlated with IOP reduction only in the OAG group (Pearson's correlation; p < 0.001). PL ratio was significantly correlated with IOP reduction in all 3 groups (Pearson's correlation; p < 0.05) and showed the best sensitivity and specificity to predict significant reduction in IOP after cataract surgery among parameters including preoperative IOP, PD ratio and PL ratio. CONCLUSIONS: PL ratio was significantly correlated with IOP reduction after cataract surgery in all 3 groups and showed a higher predictive value for IOP reduction in the OAG group than in the other groups.

Purpose: The purpose of this qualitative study was to describe the illness experiences of people with young-onset dementia who live in a community. Methods: Six community-dwelling patients with young-onset dementia, aged 65 or under, were recruited. Data were collected from August 2019 to July 2020 and analyzed using qualitative thematic analysis. Results: The data were classified into five themes and eleven sub-themes. The following themes emerged: 1) Anguish enough to want to die from dementia symptoms that hit the prime of one's life; 2) Being thrown from middle age to old age; 3) Becoming a burden due to changing roles within the family; 4) Experiencing difficulties in the diagnosis and treatment process due to onset before old age; and 5) Living with young-onset dementia in one's own life. Conclusion The findings suggest that people with young-onset dementia have unique experiences associated with middle age Korean traits. Therefore, based on their illness experiences, effective psychosocial nursing interventions tailored to their age should be developed.
