4 Ophthalmic Pathology and Intraocular Tumors
Part I: Ophthalmic Pathology
Chapter 5: Conjunctiva
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.
