4 Ophthalmic Pathology and Intraocular Tumors
Part I: Ophthalmic Pathology
Chapter 5: Conjunctiva
Highlights
-
Developmental lesions such as dermoids and dermolipomas of the conjunctiva can occur in the bulbar or forniceal conjunctiva.
-
Inflammation of the conjunctiva is common and may be infectious or noninfectious. Histologic examination may be helpful in some cases of inflammation.
-
Pinguecula and pterygium share the histologic feature of elastotic degeneration in the conjunctival stroma.
-
Ocular surface squamous neoplasia typically affects the interpalpebral limbal zone and involves varying amounts of epithelial dysplasia and cellular atypia, ranging from mild dysplasia to invasive squamous cell carcinoma.
-
Pigmentation of the conjunctiva can result from a variety of processes. These lesions may involve epithelial cells or melanocytes and often require biopsy to determine the clinical course and treatment options.
