Spectrum of metastatic tumours to orbit over the last twenty years in a tertiary care eye hospital-A retrospective study.

OBJECTIVE

To assess the type and presentation patterns of tumours metastasising to orbit.

METHODS

The retrospective study was conducted at the Al Shifa Trust Eye Hospital, Rawalpindi, Pakistan, and comprised data of all patients with orbital metastatic lesions over a 20-year period, from January 1, 2004, to December 31, 2023. Data was analysed using SPSS 22.

RESULTS

Of the 30 patients, 17(56.7%) were males and 13(43.3%) were females. The highest incidence of orbital metastatic disease was among those aged <10 years 9(30%) and >60 years 11(36.7%). Roof was the commonest site of involvement within the orbit 13(43.3%). Proptosis was the main feature at presentation. Diagnosis was made clinically in 14(46.7%) patients and histologically in 16(53.3%). All the 30(100%) cases were referred to the oncology service for further management. Of them, 2(6.7%) patients were lost to follow-up, 20(66.7%) died within one year of diagnosis, and 8 (26.6%) patients were still under treatment.

CONCLUSIONS

The diagnosis of orbital metastasis should always be considered for orbital lesions in all age groups, especially in patients with a known cancer elsewhere. Orbital metastasis usually becomes evident at an advanced stage of underlying malignancy, leading to a high mortality rate..
