Validating and updating the OHTS-EGPS model predicting 5-year glaucoma risk among ocular hypertension patients using electronic records.

Objective: To validate and update the OHTS-EGPS model predicting risk of conversion from OHT to glaucoma using electronic medical records (EMR).

Design: Evaluation and update of a risk prediction algorithm using EMRs and linked visual field (VF) tests.

Participants: Newly diagnosed OHT patients attending hospital glaucoma services in England.

Patient preferences for ocular hypertension monitoring: a discrete choice experiment.

Background/aims: To elicit the preferences and calculate the willingness to pay (WTP) of patients with ocular hypertension (OHT) for eye monitoring services in the UK.

Methods: Patients with OHT aged at least 18 years recruited from four NHS ophthalmology departments were included in the study. Patients' preferences and WTP for an OHT monitoring service in the National Health Service were elicited using a discrete choice experiment (DCE) within a postal survey based on six attributes: (1) how OHT monitoring is organised, (2) monitoring frequency, (3) travel time from home, (4) use of a risk calculator for conversion to glaucoma, (5) risk of developing glaucoma in the next 10 years and (6) cost of monitoring.

Emotional well-being in Charles Bonnet syndrome: exploring associations with negative affect, loneliness and quality of life.

Background: Charles Bonnet syndrome (CBS) is a condition characterised by the occurrence of vivid and complex visual hallucinations in individuals with visual impairment.

Objective: To explore the relationship between emotional distress and the perceived impact of CBS symptoms on participants' lives. We tested the hypothesis that heightened negative affect was associated with a more negative appraisal of CBS symptoms, increased self-reported loneliness, and poorer quality of life (QOL).
