Evaluating the association between autoimmune disease and normal tension glaucoma: a retrospective case-control study

Area of Science:

• Ophthalmology
• Immunology

Background:

• Autoimmune diseases are proposed as potential risk factors for glaucoma, a leading cause of irreversible blindness.
• Normal-tension glaucoma (NTG) may involve intraocular pressure-independent mechanisms, possibly related to inflammation or immune responses.
• Retinal ganglion cell (RGC) loss is a key feature of glaucoma.

Purpose of the Study:

• To investigate the association between autoimmune disease and normal-tension glaucoma (NTG).
• To determine if autoimmune disease diagnosis, treatment, or related laboratory markers are linked to NTG.

Main Methods:

• Retrospective case-control study.
• Enrolled 277 patients with NTG and 277 age- and sex-matched controls.
• Compared frequency of autoimmune disease diagnosis, treatment, and laboratory markers between groups.

Main Results:

• No significant difference in the overall frequency of autoimmune diseases between NTG patients and controls.
• No significant differences observed for specific autoimmune conditions, including psoriasis, rheumatoid arthritis, and Sjögren's syndrome.
• No significant differences in laboratory values or treatment of autoimmune conditions were found.

Conclusions:

• The study found no significant association between autoimmune disease and normal-tension glaucoma.
• These findings suggest that factors other than autoimmune disease may be more critical in the development of NTG.
• Further research is warranted to elucidate the pathogenesis of NTG.
