Ocular adnexal marginal zone lymphoma arising in a patient with immunoglobulin-G4-related ophthalmic disease: A 4-year delay in diagnosis.

Ocular adnexal marginal zone B cell lymphomas (MZBLs) make up the majority of lymphomas arising from the ocular adnexa. Immunoglobulin-G4 (IgG4)-related disease is a recently proposed entity with several unique clinicopathological features, such as enlargement of affected organs, elevated serum IgG4 level, and infiltration with IgG4-positive plasma cells. Ocular adnexal MZBLs are reported to arise in IgG4-related sclerosing dacryoadenitis, indicating a possible link between the two conditions.

Congenital Eyelid Anomalies: What General Physicians Need To Know.

The eyelids are important structures that maintain the health of the ocular surface and have an important role in facial esthetics. Any interruption in eyelid development can lead to congenital eyelid deformities. Eyelid abnormalities in children may present at birth due to abnormal embryogenesis (congenital) or may occur at a later stage as the child matures (developmental).

Microphthalmos-anophthalmos-coloboma (MAC) spectrum in two brothers with Renpenning syndrome due to a truncating mutation in the polyglutamine tract binding protein 1 () gene.

: Patients with intellectual disability syndromes frequently have coexisting abnormalities of ocular structures and the visual pathway system. The microphthalmos, anophthalmos, and coloboma (MAC) spectrum represent structural developmental eye defects that occur as part of a syndrome in one-third of cases. Ophthalmic examination may provide important diagnostic clues in identifying these syndromes.
