Ocular prosthesis motility and quality of life in subjects with custom ocular prostheses: A superimposed limbus test approach – A cross-sectional study

AIM: The purpose of this study was to objectively evaluate ocular prosthesis motility and its correlation with quality of life (QoL) among subjects using custom ocular prostheses. SETTINGS AND DESIGN: Cross-sectional analytical observational study conducted at the Dental and Oral Hospital, Hasanuddin University. MATERIALS AND METHODS: Forty subjects with custom ocular prostheses were evaluated. Prosthesis motility was assessed using the limbus test scheme and digitally analyzed using a superimposed method in CorelDRAW. QoL was assessed using a validated questionnaire. STATISTICAL ANALYSIS USED: Mann-Whitney U, Kruskal-Wallis, Wilcoxon signed-rank, and Spearman correlation tests. RESULTS: Compared with the contralateral normal eye, prosthetic motility showed a significant reduction, with an average loss ranging from 68% to 79%. Adduction movement was significantly associated with age (P = 0.016) and the duration of prosthesis use (P = 0.007). A significant positive correlation was found between prosthesis motility (objective measurement) and perceived QoL across several domains (ρ =0.471-0.577, P < 0.05). CONCLUSION: The average QoL of custom ocular prosthesis users was rated as good. Prosthesis motility was significantly associated with age and duration of use. Furthermore, motility has a notable impact on subject satisfaction and overall QoL.
