The contents become less homogenous and develop a "scrambled-egg" appearance (stage 2a). The lesion eventually develops a fluid, yellow-colored vitelline substance (pseudohypopyon or stage 3) and finally breaks down, leaving a scar that causes central visual acuity deterioration (20/200). This may be complicated by a subfoveal choroidal neovascular (CNV) membrane (rare in children).

Gaucher disease encompasses a continuum of clinical findings from a perinatal lethal disorder to an asymptomatic type. There are three major clinical types (1, 2, and 3) and two other subtypes (perinatal-lethal and cardiovascular). Type 1 is characterized by the presence of clinical or radiographic evidence of bone disease, hepatosplenomegaly, anemia and thrombocytopenia, lung disease, and the absence of primary central nervous system disease. GD types 2 and 3 are characterized by the presence of primary neurologic disease. Type 2 has an onset before age two years, limited psychomotor development, and a rapidly progressive course with death by age two to four years. Type 3 may have onset before age two years, but often have a more slowly progressive course, with survival into the third or fourth decade. The perinatal-lethal form is associated with ichthyosiform or collodion skin abnormalities or with nonimmune hydrops fetalis. The cardiovascular form is characterized by calcification of the aortic and mitral valves, mild splenomegaly, corneal opacities, and supranuclear ophthalmoplegia. Cardiopulmonary complications have been described with all the clinical subtypes, although varying in frequency and severity. The incidence is 1/60,000 and the prevalence is approximately 1/100,000. | 250,600 |

The age of onset is infantile. It is characterized by impaired synthesis of alpha-globin chains leading to a variable clinical picture depending on the number of affected alleles. The disease can be classified into clinical subtypes of increasing severity: silent alpha thalassemia, alpha thalassemia trait (or alpha thalassemia minor), hemoglobin H disease (HbH), and Hb Bart's hydrops fetalis (see these terms). A rare form called alpha-thalassemia-intellectual deficit syndrome has also been identified (see these terms). Alpha thalassemia trait causes microcytosis and hypochromia with absent or mild anemia (often detected on routine blood tests), generally with no other symptoms. HbH patients develop moderate hemolytic anemia with variable amounts of HbH along with occasionally severe splenomegaly, sometimes complicated by hypersplenism. Hb Bart's hydrops fetalis involves a severe deficiency in alpha-globin with serious developmental implications.
