An unusual retinal manifestation of arteriovenous communications is reported in a case showing a combination of Sturge-Weber and Kippel-Trenaunay syndromes. The arteriovenous communications are thought to be similar to those seen in the limbs in Parkes-Weber syndrome. This retinal finding indicates that the three syndromes are intricately related to each other and may be an incomplete manifestation of a single pathophysiologic entity which may be named neurocutaneous angiomatosis.
Keywords: Sturge-Weber syndrome, encephalofa-cial angiomatosis, retinal arteriovenous anastomosis, Klipel-Trenaunay Syndrome, Parkes-Weber Syndrome.

Sturge-Weber syndrome or encephalofacial angiomatosis is a phakomatosis with the usual presentation of facial nevus flammeus, glaucoma and epilepsy of early onset. , Ocular manifestations apart from glaucoma or buphthalmos are choroidal angioma, iris hypochromia, nevoid marks or vascular dilations of the episclera and retinal detachment. Overlapping of clinical findings of Kippel-Trenaunay and Sturge-Weber syndromes have been reported ,[5 ]suggesting a nosocomial relationship between the two syndromes. We report an unusual case with overlapping features of Klippel-Trenaunay and Sturge-Weber syndromes and retinal manifestation of arteriovenous communications on fluorescein angiography. This finding has not been reported in the literature to the best of our knowledge. Its relevance in the understanding of pathogenesis of these syndromes is discussed.

NS, a 15-year-old male attended the outpatient department with the complaints of recurrent seizures since the age of 11/2 years. These were described as complex parietal fits by the neurologist. The parents had observed a large, flat, red birth mark and inequality in size of the hands since birth. Developmental history suggested delayed milestones.
On examination, the patient was of average build with a large port-wine stain on the left side of the face with left sided facial hem i-hypertrophy[Figure - 1]. The nevus flammeus descended on to the neck, chest, left arm and hand and both legs from thighs to soles. The stain blanched on pressure and the left hand was larger than the right hand[Figure - 2]. The cardiovascular, respiratory and genito-urinary system were normal. Neurological examination revealed diminution of vibration sense in the upper and lower limbs.Otological examination suggested left sided sensori-neural deafness and hemangioma of the left tympanum. Electroencephalography showed multifocal epilepsy arising from the left and the right temporal region with left hemispheric damage. Radiological examination of the skull showed occipital tram-track calcifications.
Ocular examination revealed best corrected vision to be 6/6 on the Snellen's chart with +0.5 D sphere lenses in either eye. The right eye was essentially normal while in the left eye conjunctiva, cornea and anterior chamber were normal. There were no signs of rubeosis iridis which was confirmed by iris fluorescein angiography. Gonioscopic examination revealed prominent iris processes with blood in Schlemm's canal. Ophthalmoscopy showed glaucomatous cupping of the disc, retinal tortuosity and arteriovenous shunts with venous sheathing of the suprotemporal vein. On fluorescein angiography venous tortuosity, venous venous communications and arteriovenous communication were seen [Figure - 3],[Figure - 4],[Figure - 5]. No leak was observed. No choroidal or retinal angioma was seen. The intraocular pressure on applanation tonometry was 12 mm. in the right eye and 32 mm in the left eye. Visual fields showed a left homonymous hemianopia.
The epilepsy was controlled medically and the intraocular pressure was controlled by Timolol maleate drops 0.5% adminstered twice a day in the left eye.

Sturge-Weber syndrome classically involves three systems: ocular, cutaneous and neurological, all of which are neuroectodermal in origin. Variants from the classical presentation are known, which may be trisymptomatic or bisymptomatic. Besides these variants, combinations with Klippel-Trenaunay have been reported , suggesting nosocomial relationship between these syndromes which may manifest completely or incompletely.
Retinal manifestations reported in Sturge-Weber syndrome have been tortuosity and dilation of retinal vessels particularly veins,  pronounced reduction of size of the retinal arteries and sheathing of both arteries and veins  and anastomotic veins surrounding the macula.  Observation of artiovenous communication in the retina is an unusual finding observed by us. In light of the presence of features of Klippel-Weber syndrome, this finding of arteriovenous anastomosis brings into the picture the third syndrome which usually forms a triangular association with Parkes-Weber syndrome. It was Schnyder et al  who first bridged the gaps between these three syndromes i.e. Klippel-Trenaunay, ParkesWeber and Sturge-Weber syndromes. They suggested that these three syndromes are variants with a common feature of local gigantism and hemangioma. Involvement of the head and neck with manifestations of meningeal angiomatosis causing epileptic fits and choroidal hemangioma or glaucoma results in a manifestation of Sturge-Weber syndrome. Local gigantism and hemangioma of the limbs with osteohypertrophy presents as Klippel-Trenaunay or Parkes-Weber syndrome, depending on whether there are peripheral varices which causes Klippel-Trenaunay Syndrome or arteriovenous anastomosis which would result in a picture of Parkes-Weber syndrome. It suggests that the basic pathology of all the three is the same but different presentations are observed depending on differential involvement. The other feature of the syndromes are supposed to be secondary to the primary involvement of the neuro-ectodermal vasculature.
The presence of the features of Sturge-Weber syndrome i.e. nevus flammeus, unilateral glaucoma and epileptic fits with characteristic radiological tram-track signs and features of Klippel-Trenaunay syndrome (Osteohypertrophy of the left upper and both lower limbs) and a new retinal manifestation of arteriovenous anastomosis which is similar to the arteriovenous anastomosis of the peripheral limbs described in Parkes-Weber syndrome indicates a rare combination. It indicates a common pathogenetic basics for the three syndromes known by various names. We would like to refer them as 'Neuro-cutaneous Angiomatosis' which encompasses the entire spectrum of variegated appearance of this group of three syndromes.
