Sturge–Weber syndrome (SWS) or encephalotrigeminal angiomatosis is a rare congenital and dermatological disorder. It is one of the phakomatoses and is associated with unilateral port-wine stain of the face, ipsilateral glaucoma, seizures, mental retardation, and ipsilateral leptomeningeal angioma. However, different variants have been described. We describe the case of a 13-year-old female patient with bilateral SWS associated with advanced glaucoma in both the eyes and absent neurological involvement. Surgical treatment with Ahmed glaucoma valve was performed in both the eyes at an interval of 2 weeks for achieving a lower level of intraocular pressure.

  Introduction Top

Sturge– Weber syndrome More Details (SWS) is one of the hamartomatoses or phakomatoses. It is a rare neuro-oculocutaneous disorder with an estimated incidence of one in 50,000 births.[1] Clinically, the neurological manifestations include epilepsy, mental retardation, and hemiplegia; the ocular manifestations include glaucoma and vascular malformations of the conjunctiva, episclera, choroid, and retina; and the dermal manifestations include nevus flammeus or port-wine stain.[2]

Glaucoma is a frequent association with SWS. It is seen in as many as 50% of the cases when the port-wine stain involves the maxillary and ophthalmic branches of the trigeminal nerve.[3] However, the prognosis of glaucoma associated with SWS, despite treatment, is often poor.[4]

In this case report, we describe the case of a 13-year-old female patient with bilateral SWS associated with advanced glaucoma in both the eyes and absent neurological involvement.

Case Report

A 13-year-old female patient was referred from the Paediatric Department for the evaluation of the ocular manifestations of SWS and low visual acuity in the right eye. She had a bilateral facial angioma sparing the right side of the forehead since birth [Figure 1]. Best-corrected visual acuity was 1/60 in the right eye [−4.50 diopter cylinder (DC) × 90°] and 6/9 in the left eye (−3.0 DC × 90°). Grade 3 relative afferent papillary defect was present in the right eye. Dilated episcleral vessels were noted in both the eyes [Figure 2]. Intraocular pressure measured by Goldmann applanation tonometer on presentation was 50 mmHg in the right eye and 42 mmHg in the left eye at 10.00 AM. Fundoscopy revealed total glaucomatous optic atrophy in the right eye and cup-to-disc ratio of 0.7 in the left eye [[Figure 3] and [Figure 4]]. Central corneal thickness was 508 and 525 μm in oculus dexter (OD) and oculus sinister (OS), respectively. Horizontal and vertical corneal diameter was 13 mm in both the eyes. On gonioscopy, anterior chamber angle was open in both the eyes with blood in the Schlemm’s canal. A visual field assessment of the left eye showed severe constriction with a sparing of central vision [[Figure 5] and [Figure 6]]. A visual field assessment of the right eye was not possible due to low visual acuity. No evidence of choroidal vascular malformations was seen in either eye. Axial length was 22.76 mm in the right eye and 22.32 mm in the left eye. Ultrasound B scan revealed increased optic nerve head cupping in both the eyes. The magnetic resonance imaging (MRI) of the brain revealed normal findings.

The patient was started on oral and topical medical therapy for the control of intra ocular pressure (IOP) and planned for glaucoma surgery in the left eye with a drainage device.

A decision for surgical management in the form of Ahmed glaucoma valve implantation in both the eyes was taken because trabeculectomy in patients with SWS is associated with higher chances of failure due to trabecular dysgenesis and higher chances of postoperative complications such as choroidal effusion. The patient underwent Ahmed glaucoma valve implantation in the left eye [[Figure 7] and [Figure 8]] and was continued on topical medical therapy in the right eye. The valve was secured to the sclera using a 10-0 nylon suture and the conjunctiva was closed using 6-0 silk sutures, because both these steps warranted the use of nonabsorbable sutures. Postoperative outcome was satisfactory in the left eye. After 2 weeks, the patient underwent glaucoma valve implantation in the right eye as well. At 1-month follow-up, the IOP was 12 and 10 mmHg in OD and OS, respectively. Best-corrected visual acuity was maintained at 6/9 in the left eye. Visual acuity in the right eye was 1/60 with the projection of rays accurate in all quadrants due to advanced glaucomatous optic neuropathy.

  Discussion Top

Glaucoma associated with SWS is usually a unilateral condition.[3] The case described in this study is that of a bilateral presentation with asymmetric optic disc damage.

The pathophysiology of glaucoma in SWS has been under investigation for many years, and various mechanisms for the same are theorized. When glaucoma is present at birth, it is due to a malformation of the anterior chamber angle, and patients manifest the typical signs of congenital glaucoma, including buphthalmos, anisometropia, and amblyopia. In later-onset juvenile glaucoma, the anterior chamber angle mostly appears normal. It is suggested that elevated episcleral venous pressure plays an important role in glaucoma associated with SWS.[5] Another mechanism of glaucoma is thought to be caused by the premature ageing of the trabecular meshwork and Schlemm’s canal complex leading to early-onset chronic open angle glaucoma.[6]

Medical therapy for glaucoma in SWS is often inadequate, and most patients require surgical intervention for the control of intraocular pressure. Trabeculectomy is associated with a number of postoperative complications including choroidal effusion.[7] Goniotomy and trabeculotomy have been described as treatment modalities in early-onset glaucoma.[3] Less frequent complications have been found to be associated with glaucoma drainage devices.[8],[9] This was the reason for the choice of this procedure as primary treatment modality in our case.
