The most common complaints in Salzmann’s nodular degeneration are reduced visual acuity, excessive tears, photosensitivity and a sensation of sand grit. However, the condition can also be asymptomatic. It shows up as greyish-white to bluish thickening at the front of the cornea.
To date, no clear cause for this condition has been described. Chronic corneal diseases could increase the risk of Salzmann’s nodules. It often co-occurs with chronic dry eye, chronic blepharitis, trichiasis (eyelashes growing towards the eye), and previous eye trauma and surgery. Still, it seems to occur without such a history in many cases. There may also be a hereditary factor, and there seems to be a connection with Crohn’s disease.
The eye and the cornea are first examined in detail to make a proper diagnosis and draw up a treatment plan. In addition to the standard examinations, the following ones are specifically important in the case of Salzmann’s nodular degeneration:
When the eye feels uncomfortable, eye drops may be prescribed. The eye drops moisturise the eye. They can be used throughout the day.
If you experience reduced vision, a phototherapeutic keratectomy may be considered.
