Progression of scleral disease

Area of Science:

• Ophthalmology
• Clinical Medicine

Background:

• Scleritis, an inflammation of the sclera, can be classified based on its anatomical location and clinical presentation.
• Understanding the natural history of different scleritis types is crucial for effective management and predicting outcomes.

Purpose of the Study:

• To evaluate if a classification system for scleritis based on anatomical site and clinical appearance at presentation correlates with its natural history.
• To analyze the progression, recurrence, and visual outcomes associated with different types of scleritis.

Main Methods:

• Retrospective review of clinical features in 290 patients diagnosed with scleral inflammation.
• Classification of patients based on anatomical site (anterior/posterior) and clinical appearance (diffuse, nodular, necrotizing).

Main Results:

• The majority of patients remained in their initial clinical category throughout the disease course.
• Necrotizing scleritis patients were older, more frequently had associated systemic diseases, and showed the highest visual loss (74%).
• Diffuse anterior scleritis had the lowest visual loss (9%), while nodular scleritis (26%) and posterior scleritis (84%) represented intermediate and severe visual impairment, respectively.

Conclusions:

• The proposed classification system for scleritis appears to reflect its natural history.
• Scleritis severity varies significantly, with necrotizing and posterior forms posing the greatest threat to vision.
• Early identification and appropriate management strategies are essential, particularly for severe scleritis subtypes.
