Seeing beyond Gaucher disease: Early detection and treatment of ocular complications
Background: Gaucher disease is a rare genetic disorder caused by a deficiency in the enzyme glucocerebrosidase, which impairs the body's ability to break down certain fats. This leads to the accumulation of glucosyl sphingosine and glucosyl ceramide in the liver, spleen, and bone marrow. Gauche...

| Summary: | Background: Gaucher disease is a rare genetic disorder caused by a deficiency in the enzyme glucocerebrosidase, which impairs the body's ability to break down certain fats. This leads to the accumulation of glucosyl sphingosine and glucosyl ceramide in the liver, spleen, and bone marrow. Gaucher disease has two major types: nonneuropathic (Type 1) and neuropathic (Type 2 and Type 3). Gaucher disease can have various ophthalmologic manifestations, particularly in Type 3, including posterior segment abnormalities, such as vitreous opacities, condensations, and/or preretinal white dots. We present a case of a patient with Gaucher disease Type 3 who had severe bilateral vitreous and extensive retinal deposits, leading to challenges during surgery. Purpose: This video reports surgical outcomes for an uncommon ophthalmologic manifestation in a patient with Gaucher disease Type 3. We focus on the challenges and results of surgery for severe bilateral vitreous and extensive retinal deposits. Synopsis: A 16-year-old female patient with a history of Gaucher's disease since birth presented with a one-year history of blurred vision in both eyes. Her best-corrected visual acuity was 20/200 in the right eye and 20/100 in the left eye, as measured by Snellen's chart. Intraocular pressure was normal in both eyes, and anterior segment examinations were unremarkable. However, fundus evaluation revealed extensive vitreous deposits that obscured the details of the fundus. Additionally, an epiretinal membrane was observed over the macula in both eyes. Optical coherence tomography (OCT) confirmed the presence of deposits in the vitreous cavity and on the surface of the retina. The patient underwent pars plana vitrectomy with epiretinal membrane removal. A transconjunctival 23-G pars plana vitrectomy was performed to the extent possible. Multiple instruments were used to remove the fluffy vitreous deposits, as they were extremely adherent to the underlying surface of the retina, and brilliant blue dye was used to stain the internal limiting membrane. The epiretinal membrane and internal limiting membrane were removed from the macular area, and the entire cassette fluid was sent for histopathological examination to identify Gaucher cells. At one week postoperative, the patient's visual acuity improved to 20/125 in the right eye, and the fundus picture showed a cleared macular area. OCT showed a reduction in deposits over the retina. The histopathological examination revealed crumpled, barrel-like cytoplasm with an oval nucleus in a hemorrhagic background, suggestive of Gaucher cells. Highlights: Early detection and treatment of ocular manifestations of Gaucher's disease are important to prevent permanent damage to vision. An ophthalmological assessment involving a dilated fundus examination and optical coherence tomography can facilitate early diagnosis and follow-up of ocular manifestations. Timely surgery may be required to preserve functional vision in patients with severe ocular disease.
