Abstract:
AIM: To analyze the clinical features and multimodal imaging features of peripapillary hyper-reflective ovoid mass-like structure(PHOMS).METHODS: Retrospective observation study. Totally 35 patients(56 eyes)with PHOMS that diagnosed in the Affiliated Eye Hospital of Nanjing Medical University from January 2020 to March 2024 were included in the study. All patients underwent fundus photography, fundus fluorescein angiography, fundus autofluorescence, optical coherence tomography, and B-ultrasound.RESULTS:PHOMS occurred across diverse age groups, with an insidious onset often detected incidentally during routine ophthalmic examinations. More patients came to hospital for refractive errors due to blurred vision The boundary of the optic disc is blurred on fundus photography, and the nasal eminence is more significant, showing a “C” shaped halo. No obvious abnormal fluorescence was observed on fundus autofluorescence and fundus fluorescein angiography during different periods. An elevated appearance in vary degrees with more prominent in the nasal parts was showed on different OCT scans. Vertical scanning on the nasal side of the optic disc showed the best PHOMS structure, which could be seen under the retinal nerve fiber layer and on the Bruch membrane, with sharply marginated hyper-reflective ovoid mass-like structures, and no shielding effect on the choroid. The higher the elevation, the larger the volume. Ocular B-mode ultrasound showed a pre-optic disc bulge on the posterior wall of the eyeball, and there was no strong signal echo in it.CONCLUSION:PHOMS can be found frequently in myopic patients and often asymptomatic. Transient vision loss and floaters may occur in symptomatic cases. The most typical OCT feature is a nasally located hyper-reflective ovoid structure with distinct margins.
