Perception of patients with retinal pathology on aspects of visual function and their management

BACKGROUND AND OBJECTIVE

Age-related macular degeneration (AMD) and diabetic retinopathy (DR) are highly prevalent.

OBJECTIVE

To explore perceptions of patients with AMD or DR about the impact of the disease and treatment on their daily living activities.

MATERIALS AND METHODS

Semi-structured interviews with a questionnaire developed from validated patient reported outcomes questionnaires. The questionnaire consisted of 19 questions about the disease and 9 about the treatment. The questions (items) were answered on a scale from 1 to 9. In addition, the patient interviewed was invited to make free comments on each question. Nine patients with AMD and 9 with DR were interviewed by videoconference or telephone call. A quantitative analysis of the responses and a qualitative analysis of the comments were carried out.

RESULTS

The most relevant item for patients with AMD or DR is "Recognize people when they are nearby", and "Read text in normal size font in a newspaper or book", followed, in patients with AMD, by "Do things what you would like" and, in patients with DR, "Feeling frustrated by the vision problems." Regarding the treatment, the most relevant aspects for both groups is that the treatment works and receiving appropriate information before and after the treatment. The qualitative comments were focused to the disease, the treatment, and to the role of doctors and the health system.

CONCLUSION

Quantitative responses and free comments can be useful to improve the care of patients with AMD or DR by physicians and the health system.

Exploring self-reported visual function and vision-related anxiety in patients with RPGR-associated retinal degeneration

Variants in the retinitis pigmentosa GTPase regulator (RPGR) gene are responsible for the majority of X-linked retinitis pigmentosa cases, which not only affects male patients but also some heterozygous females. Vision-related disability and anxiety of patients with RPGR-associated retinal degeneration have never been explored before. This study aimed to evaluate self-reported visual function and vision-related anxiety in a Portuguese cohort of male and female patients with RPGR-associated retinal degeneration using two validated patient-reported outcome measures. Cross-sectional data of thirty-two genetically-tested patients was examined, including scores of the Michigan retinal degeneration questionnaire (MRDQ) and Michigan vision-related anxiety questionnaire. Patients were classified according to retinal phenotypes in males (M), females with male phenotype (FM), and females with radial or focal pattern. Both M and FM revealed higher rod-function and cone-function anxiety scores (p < 0.017). Most MRDQ disability scores were higher in M and FM (p < 0.004). Overall, positive correlations (p < 0.004) were found between every MRDQ domain and both anxiety scores. In RPGR-associated retinal degeneration, males and females with male phenotype show similar levels of increased vision-related anxiety and disability. Every MRDQ visual function domain showed a strong correlation with anxiety scores.

Quality of life in glaucoma

BACKGROUND

An essential goal of glaucoma management is to prevent a patient's visual impairment that compromises their health-related quality of life (QOL). The disease itself, in addition to the medical or surgical treatment, can have a large impact on one's life. We aim to briefly review and evaluate aspects of QOL in glaucoma.

METHODS

The PubMed database was utilized for the literature examination of this review. Keywords that were searched included glaucoma, quality of life, vision-related QOL (VRQOL), quality of life questionnaire, and glaucoma therapy.

RESULTS

The main topics identified and analyzed during the literature review stages include factors affecting VRQOL, the assessment of VRQOL using questionnaires, QOL in early and severe glaucoma, glaucoma and activities of daily living, glaucoma treatments, and new advances in clinically assessing QOL. The study findings indicate a relationship between the deterioration of visual field and the quality of life. The investigation shows that visual loss can result in a range of daily life challenges, which include compromised mental health status and difficulties with driving, reading, and recognizing people.

CONCLUSION

Glaucoma-induced visual field loss can significantly impact different aspects of patients' life, and several methods exist for evaluating changes in quality of life. Quality of life assessments have their limitations as they are subjective. As potential future steps, we suggest exploring technological advancements such as virtual reality to improve patient care and outcomes.

Self-reported visual function and psychosocial impact of visual loss in EYS-associated retinal degeneration in a Portuguese population

PURPOSE

To evaluate self-reported visual function and the psychosocial impact of visual loss EYS-associated retinal degeneration (EYS-RD) using two patient-reported outcome (PRO) measures: Michigan Retinal Degeneration Questionnaire (MRDQ) and Michigan Vision-related Anxiety Questionnaire (MVAQ).

METHODS

Cross-sectional, single-center study conducted at a tertiary care hospital in Portugal. Patients with biallelic EYS variants were invited to participate. Clinical data including demographics, ETDRS best-corrected visual acuity (BCVA) in the better-seeing eye and genetic testing results were collected. Interviews were carried out during clinic visits or by phone between November 2021 and February 2022. A blind grader used horizontal and vertical spectral domain optical coherence tomography (SD-OCT) scans to manually measure ellipsoid zone (EZ) width in the nasal, temporal, superior and inferior macular quadrants to calculate the EZ area.

RESULTS

Forty-nine patients (53.1% males; mean age 53 ± 14 years) were included. A positive correlation (p < .05) was found between age and most MRDQ domain scores (central vision, color vision, contrast sensitivity, scotopic function, photopic peripheral vision and mesopic peripheral vision). A negative correlation was found between both BCVA and EZ area across all MRDQ domains. In MVAQ, SD-OCT EZ area negatively correlated with both rod function and cone function-related anxiety. Neither age, BCVA or gender correlated with MVAQ domains.

CONCLUSIONS

This study provides strong evidence supporting a correlation between PRO measures and both functional and structural clinician-reported outcomes. The use of MRDQ and MVAQ adds a new dimension to our understanding of EYS-RD and establishes both PRO measures as important disease outcome measures.
