Orbital Venous Anomalies

An unusual case, Bilateral orbital varices

“…Bilateral orbital varices are quite rare (Safran et al 1984). In the reviewing study of 158 patients with orbital venous anomalies which include both lymphangiomas and primary orbital varices, Wright et al (1997) did not report any bilateral lesions.…”

Late ocular manifestation of a childhood venous-lymphatic malformation

“…4 Phleboliths occur in one-third of cases. 3 Histology can confirm the diagnosis by revealing irregular dysplastic endothelial channels, with a dense stroma containing smooth muscle, haemosiderin-laden macrophages, and lymphocytes. 3,4 In this case, it is difficult to elucidate whether ocular involvement is due to a primary OVLM or secondary to extension.…”

“…3 Histology can confirm the diagnosis by revealing irregular dysplastic endothelial channels, with a dense stroma containing smooth muscle, haemosiderin-laden macrophages, and lymphocytes. 3,4 In this case, it is difficult to elucidate whether ocular involvement is due to a primary OVLM or secondary to extension. If it is due to primary involvement, an earlier ocular presentation might be expected, although it is possible that the decrease in left visual acuity is related to a long-standing OVLM, rather than 'true amblyopia'.…”

“…Conjunctival and episcleral involvement is common. 3 Lesions can extend to ipsilateral hard or soft palate and face. Intervention is advised only in cases of compressive optic neuropathy, strabismus, or cosmetic deformity.…”

“…Intervention is advised only in cases of compressive optic neuropathy, strabismus, or cosmetic deformity. 1,3 MRI shows irregular, multi-loculated, heterogeneous masses that are not confined to any fascial planes. 4 Phleboliths occur in one-third of cases.…”
