The Quality of Life of Medically Versus Surgically Treated Primary Open-angle Glaucoma Patients at a Nigerian Hospital.
PURPOSE: The purpose of this study is to compare the quality of life (QoL) of medically treated versus surgically treated primary open-angle glaucoma (POAG) patients attending Lagos University Teaching Hospital, Lagos, Nigeria.
METHODS: The study was a hospital-based, comparative cross-sectional study. Consecutive consenting POAG participants who met the inclusion criteria were recruited until the sample size was achieved. QoL of all participants was assessed using the glaucoma QoL-15 and National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) questionnaires. Analysis was done using the IBM statistical package for the social sciences version 25.0.
RESULTS: The study involved 81 participants who were only on medical treatment for POAG and 81 age- and sex-matched POAG participants who had trabeculectomy surgery. Surgically treated participants had a lower mean intraocular pressure 11.68 mmHg when compared to the medically treated participants 14.82 mmHg. Medically treated participants however had a better overall mean glaucoma QoL using the glaucoma QoL-15 (medical 34.36 ± 10.4, surgical 39.11 ± 13.9 P = 0.015) and NEI-VFQ-25 questionnaires (medical 68.32 ± 15.0, surgical 62.44 ± 18.8 P = 0.029). Controlling for the severity of glaucoma using the glaucoma QoL-15 questionnaire, medically treated participants had a better QoL only among participants with severe POAG (medical 49.13 ± 5.9, surgical 54.06 ± 4.6 P = 0.003). While using the NEI-VFQ-25 questionnaire, medically treated participants had a significantly better QoL only among participants with moderate (medical 74.70 ± 6.6, surgical 67.07 ± 15.6 P = 0.012) and severe POAG (medical 54.52 ± 6.3, surgical 45.51 ± 10.0 P = 0.004).
CONCLUSION: The study demonstrated that although participants that had trabeculectomy had a lower mean intraocular pressure, their overall mean QoL was reduced compared to the medically treated participants.
