Summary
Pingueculae, typically linked to sun and dust exposure, are rarely associated with Sjögren's syndrome. This report details two novel cases of pinguecula development in patients with Sjögren's syndrome.
Area of Science:
- Ophthalmology
- Rheumatology
- Immunology
Background:
- Pinguecula is a common conjunctival degeneration.
- It is typically associated with chronic exposure to ultraviolet radiation, dust, and wind.
- The pathogenesis involves conjunctival microtrauma and inflammation.
Observation:
- Two cases of pinguecula formation in patients with Sjögren's syndrome are presented.
- Sjögren's syndrome is an autoimmune disease primarily affecting exocrine glands, leading to dry eyes and mouth.
- The conjunctival nodules appeared in the temporal or nasal limbus.
Findings:
- This represents a previously undescribed association between pinguecula and Sjögren's syndrome.
- The development of pinguecula in these cases may be linked to the chronic ocular surface inflammation characteristic of Sjögren's syndrome.
- Further research is needed to elucidate the underlying mechanisms.
Implications:
- This finding suggests a potential link between autoimmune conditions and the development of pingueculae.
- Ophthalmologists should consider Sjögren's syndrome in patients presenting with pingueculae, especially those with other autoimmune risk factors.
- This association may warrant further investigation into the role of systemic inflammation in ocular surface diseases.
