Real-world experience of implementing the MOLES score in a virtual choroidal naevi clinic at a tertiary referral centre

Abstract

Introduction

The MOLES score has been validated to clinically differentiate choroidal naevi from melanomas by ocular oncologists and community optometrists. However, its utility in a virtual choroidal naevi clinic at a tertiary eye hospital without specialist ocular oncology services has not yet been evaluated.

Methods

A retrospective case review of 385 choroidal lesions in the virtual choroidal naevus clinic at Bristol Eye Hospital during January–March 2020 and April–August 2021 was performed. Choroidal lesions were assessed using the TFSOM-UHHD risk factor index and MOLES score, respectively. For both study periods, clinical outcome and adherence data were analysed.

Results

Choroidal lesions scored higher with the TFSOM-UHHD index (median 2) compared to the MOLES score (median 0; p < 0.001). Median required follow-up duration was 2 years for lesions assessed with the TFSOM-UHHD index, and 0 years for those graded with the MOLES score. Overall, 215 patients were appropriately discharged to community optometrists based on their MOLES score. Imaging requirements for the TFSOM-UHHD index and MOLES score protocols were met in 69.1% and 94.8% of cases, respectively.

Conclusion

The MOLES score was easily implemented in a virtual choroidal naevus clinic, with good adherence. It increased clinic capacity by facilitating appropriate discharges of low-risk naevi to community monitoring, allowing finite and specialist hospital-based services to monitor higher-risk naevi more closely.
