A 10-year-old retarded child was seen by an ophthalmologist because of strabismus. Examination of the optic nerve heads revealed cupping consistant with glaucoma and initiated a referral. The appearance of this girl, with flat-broad based thumbs and toes, small head, low set ears, high arched brows, antimongoloid slant to the eyes, high arched palate, associated with mental retardation, and strabismus suggested the Rubinstein-Tabyi Syndrome. Gonioscopy revealed a high iris insertion, while tonometry indicated mildly elevated pressures in the right eye. Examination of the optic nerve heads showed large glaucomatous type cups, more so on the right with compromise of the temporal rim. Trabeculectomy was effective in controlling the intraocular pressure in the right eye. The association of juvenile glaucoma with the Rubinstein-Taybi Syndrome requires that ophthalmic referral to assess glaucoma be an essential part of the evaluation.

Sturge-Weber syndrome (SWS) is rare congenital disorder presenting facial port-wine stains (PWS) eye abnormalities and cerebrovascular malformations. The frequency of SWS is estimated at 1 in 50 000. Cerebrovascular abnormalities can be responsible for seizures, hemiparesis, mental retardation and ophthalmologic abnormalities cause intraocular pressure, glaucoma. Etiopathogenesis of SWS remains elusive. We present a case of a 7-year-old girl with SWS type II. A port-wine stain involves the upper right part of half face and has been associated with glaucoma of both eyes. In the Department of Dermatology in 2009-2012 we performed 23 procedures within 2 months. We have been using PDL laser at wavelength 595 nm and very good cosmetic results were achieved. Given positive treatment effects, the laser therapy of port-wine stains is a method of selection. Port-wine stains in the course of SWS requires a large number of laser treatment.

Sturge-Weber syndrome (SWS) (encephalotrigeminal angiomatosis) is a phakomatosis associated with port-wine stains of the face, seizures, mental retardation, and usually ipsilateral meningeal vascular malformations. The classic form affects leptomeninges, eyes, and face. Although the precise etiology and pathogenesis are unclear, the postulated defect is primary venous dysplasia with failure of the primordial embryonic venous plexus to regress. A spontaneous somatic mutation in fibroblast fibronectin gene expression in the vascular malformation may occur during embryonic development. Ocular involvement is characterized by conjunctival, episcleral, retinal, and choroidal vascular abnormalities. The vascular lesions have been inconsistently described as angiomas, hemangiomas, and vascular malformations. Based on the endothelial cellular activity, they can be considered vascular malformations (or port-wine stains), which never regress spontaneously. Congenital, developmental, and adult-onset glaucoma are often seen when the malformations involve the distribution of the first branch of the trigeminal nerve.Both mechanical and vascular causes have been proposed to account for the development of glaucoma. The mechanical theory is based on obstruction of aqueous outflow secondary to developmental anterior chamber angle abnormalities, and the vascular theory is based primarily on elevated episcleral venous pressure. Management of glaucoma in patients with SWS is often challenging and is aimed at controlling intraocular pressure and preventing progressive visual loss and blindness. It also carries an increased risk for surgical complications. This review summarizes the literature regarding the genetics, clinical features, and management of ocular complications of SWS with special focus on glaucoma.

Glaucoma drainage device implantation is efficacious for the treatment of pediatric glaucoma patients when multiple angle surgeries fail. However, tube touching of the corneal endothelium is one of the major postoperative complications to deal with. A 15-month-old male patient with Wilms' tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome was diagnosed with bilateral developmental glaucoma. He underwent Baerveldt glaucoma implant (BGI) surgeries in both eyes after multiple failed trabeculotomies. The tube in his right eye was touching the cornea 15 months after BGI surgery. To avoid corneal endothelium damage, BGI tube repositioning with scleral fixation was performed without serious complications. The bilateral BGI surgeries achieved successful intraocular pressure reduction for over 2 years and tube repositioning with scleral fixation of BGI tube was successful for BGI tube malposition. Although careful attention to intraocular pressure and tube malposition is essential after glaucoma drainage device implantation, especially in pediatric cases, BGI surgery is effective in the management of developmental glaucoma following unsuccessful angle surgeries.

Lowe syndrome (the oculo-cerebro-renal syndrome of Lowe, OCRL) is a multi-system disorder that affects the eyes, nervous system, and kidney. OCRL is a rare X-linked recessive disease with a prevalence of approximately 1 : 500,000. The clinical features of OCRL include congenital cataracts, growth and mental retardation, areflexia, hypotonia, and renal tubular dysfunction (Fanconi-type). Chronic metabolic acidosis and hypotonia may be the most important component affecting management of the peri-anesthetic period during general anesthesia. However, problems such as electrolyte imbalance, seizure, fragility of the bone structures, and increased intraocular pressure should also be considered during the perioperative period. We report here the perioperative management of a patient with Lowe syndrome during the removal of multiple scalp cysts under general anesthesia.
