Bilateral Sturge- Weber syndrome More Details More Details (SWS) is rare but glaucoma associated with it is common. Diffuse choroidal hemangioma (CH) may be associated with SWS and remain asymptomatic throughout childhood. Its presence, however, poses several sight-threatening challenges in the surgical management of glaucoma.,
| Case Report|| |
Our patient was diagnosed with bilateral SWS [Figure 1]a and glaucoma at 5 years of age. On fundoscopy [Figure 1]b and [Figure 1]c, retinal nerve fiber layer (RNFL) changes were seen mostly inferiorly in OS with multiple drusenoid deposits [Figure 1]c; notably, there was a subtle difference in color [Figure 1]b and [Figure 1]c. CH was excluded by optical coherence tomography (OCT). She had a history of trabeculectomy + mitomycin C in OS at 7 years and massive sight-threatening choroidal detachment (CD) involving the posterior-pole in all quadrants necessitating oral steroids for 3 weeks, in the immediate postoperative period. One-year later, intraocular pressure (IOP) remained uncontrolled in OS. The non-valved glaucoma drainage device (GDD), Aurolab Aqueous Drainage Implant (AADI) was implanted under cover of perioperative propranolol (2 mg/kg) with three occlusive ligatures [[Figure 2] left] along with three pairs of fenestrations anterior to it [[Figure 2] left and right].

Postoperatively there was no hypotony or shallow anterior chamber (AC). Stepwise ligature autolysis ensured that there was no precipitous drop in IOP at around 5–6 weeks. At 1-year follow-up, the vision was 20/30 in OS with controlled IOP (13 mmHg) without medications; fellow-eye is controlled with medications.
| Discussion|| |
When CH is present, a sudden decompression of the globe or prolonged hypotony may lead to rapid transudation of fluid into the extravascular space causing choroidal and retinal effusions. Oral propranolol is hypothesized to stabilize the vascular membrane and was, therefore, used under careful systemic watch, commencing 1-week prior, and continued for 6-weeks postoperatively. CH is best diagnosed with an OCT or B-scan; even though OCT was equivocal, diffuse CH in the LE was suspected clinically—the subtle difference in the fundus color, presence of drusen-like structures, and the history of CD post initial filtration—all heightened that suspicion.
Standard treatment guidelines are not available in SWS but the use of valved GDD is emerging as the preferred option; despite flow restriction, they are not immune to a CD. Budenz et al. did use the non-valved device Baerveldt Glaucoma Implant (BGI) but only as a two-stage procedure, along with prophylactic posterior sclerotomies. We used indigenously manufactured AADI with safety and efficacy comparable to BGI (not available in India), and at a fraction of the cost of the valved device available.
The preemptive measures, in this case, made non-valved surgery safe and the need for a second stage and/or prophylactic posterior sclerotomy was obviated. It also highlights that index for clinical suspicion of CH should be high.
