  • Clinical characteristics of pseudopapilledema combined with peripapillary hyper-reflective ovoid mass-like structures in children

    ObjectiveTo observe the clinical characteristics and optical coherence tomography (OCT) features of pseudopapilledema (PPE) combined with peripapillary hyper-reflective ovoid mass-like structures (PHOMS) in children. MethodsA retrospective observational study. From October 2019 to May 2021, total 22 eyes from 12 children diagnosed as PPE combined with PHOMS in the Neuro-ophthalmology Department of The First Hospital of Xi’an (Affiliated of The First Hospital of Northwest University) were recruited. Among the children, 6 were male and 6 were female. The average age was (10.6±2.7) years. The average course from disease onset to diagnosis of PPE combined with PHOMS was (8.0±7.5) months. All patients underwent best corrected visual acuity (BCVA), relative afferent papillary defect (RAPD), Ishihara's test, fundus photography, OCT, fundus autofluorescence (FAF), ocular B-mode ultrasound, visual field and patternvisual evoked potential (P-VEP). The clinical and OCT characteristics of the patients were observed. ResultsThe anterior segments of the patients were normal. The intraocular pressures and Ishihara's test were all normal. All RAPD were negative. Total 22 eyes, BCVA was 1.0 in 21 eyes and one eye was 0.12. The fundus photography revealed blurred optic discs margin, showing mild to moderate edema-like elevation with more prominent in the nasal parts, presenting as a “C” shape halo. No obvious abnormal fluorescence was observed in FAF. The OCT scan of involvement eyes showed an elevated appearance in vary degrees, and the sharply marginated ovoid hyper-reflective mass-like structures which laterally herniated into the peripapillary region under retinal nerve fiber layer and above the Bruch membrane were detected with consecutive nasal enlargement scanning, corresponding to the nasal parts in the fundus photography. The higher degree of elevation, the larger the volume. Macular retina pigment epithelium layer and ganglion cell thickness were normal. Ocular B-mode ultrasound showed that the head of the optic nerve in the posterior wall of the eyeball (in front of the optic disc) was elevated in all affected eyes, and there was no strong signal echo in it. Visual field examination showed physical blind spot enlargement in 3 eyes and visual field defect in 2 eyes. P-VEP examination showed that the peak was slightly delayed in 3 eyes and the amplitude was slightly reduced in 3 eyes. ConclusionsEnlarged nasal optic disc OCT scan can improve the detection rate of PHOMS. PHOMS were detected bilaterally in the cases with binocular PPE while only in the effected eye in the cases of monocular PPE; the higher degree of PPE, the lager volume of PHOMS. PHOMS were could contribute to the diagnosis of PPE in children.
