• Salzmann nodular degeneration
  13 March 2021

  Definition : Salzmann’s nodular degeneration SND is a slowly progressive condition in which gray-white to bluish nodules measuring 1-3 mm are seen anterior to Bowman’s layer of the cornea, usually bilaterally.
  These elevated nodules can be located near the limbus or in the mid-peripheral cornea.
  Microscopy
  Light microscopy (figure 1) reveals dense deposits of hyalinized, irregularly arranged collagen fibers anterior to a fragmented and sometimes absent Bowman’s layer.
  The tissue overlying (...)

• ectopic cilia
  16 November 2020

  Definition : Cilia are normally found at the eyelid margin, while ectopic cilia are one or more lash follicles appearing in an abnormal position within the eyelid.
  While anterior ectopic cilia are congenital, ectopic cilia in the palpebral conjunctiva may be acquired, and these aberrant cilia are associated with crypts of Henle and chronic inflammation.

• epiphora
  16 November 2020

  lacrimation, lachrymation
  Patients will frequently present with "a watery eye" or "a tearing eye." Historically, this was called epiphora, but there have been recent variations in the use of different terms. Lacrimation (or lachrymation) is derived from "lacrima," Latin for tear, and essentially means "production of tears," although it is often used to describe the "shedding of tears," or to cry. Lacrimation may be basal (basic tear production), reflexive (to stimuli such as surface (...)

• conjunctival squamous cell carcinoma
  5 October 2019

  PO
  Conjunctival carcinomas are defined asmicroinvasive with ≤0.2 mm invasion of the chorion (miSCC) or over 0.2 mm (invasive SCC).
  Squamous cell carcinoma of the conjunctiva (SCCC) is a relatively common cancer in Africa. About one third of the total cases of SCCC occurring in Africa are HIV-related.
