A rare case of overlapping Sturge–Weber syndrome and Klippel–Trenaunay syndrome associated with bilateral refractory childhood glaucoma

A 6-year-old girl presented with blurred vision and was found to have elevated intraocular pressure (IOP) and glaucomatous optic disc damage in both eyes. She also displayed capillary malformations on the face (port-wine stain), upper back and all four limbs, angiomatosis in the brain and had hypertrophy of the left upper and lower limbs typical of overlapping Sturge–Weber syndrome and Klippel–Trenaunay syndromes. She was initially managed with IOP lowering topical medications but required trabeculectomy in the right eye followed by Ahmed valve implantation in both eyes. Despite multiple measures over a 7-year period, her IOP still remained uncontrolled with gradual progression of the glaucomatous damage. This case exhibits a very rare occurrence of overlapping syndromes reported only a handful of times in literature. Most cases with Sturge–Weber syndrome have ipsilateral glaucoma affecting the eye on the same side as the port-wine stain. This case presented with bilateral refractory childhood glaucomas, which is exceedingly rare.
