Visualization of retinal vasculitis in Eales' disease.

Area of Science:

• Ophthalmology
• Retinal Vascular Diseases

Background:

• Eales' disease is a rare condition affecting young adults, characterized by inflammation and occlusion of retinal vessels.
• It often presents with vitreous hemorrhage and can lead to significant vision loss.

Purpose of the Study:

• To analyze the clinical characteristics, progression, and visual outcomes of Eales' disease.
• To emphasize the importance of regular monitoring and fluorescein angiography for early detection and management.

Main Methods:

• Retrospective analysis of 466 patients diagnosed with Eales' disease between 1970 and 1991.
• Detailed examination of fundus changes, vitreous hemorrhage, retinal lesions, and visual acuity.
• Utilized fluorescein angiography to assess vascular abnormalities.

Main Results:

• The mean age at diagnosis was 30 years, with a mean follow-up of 43.5 months.
• Vitreous hemorrhage was observed in 257 eyes; common retinal lesions included neovascularization and vascular sheathing.
• Initially unilateral cases (110) showed a risk of bilateral involvement, with 49 progressing to bilateral disease.
• Visual acuity improved from 68.1% to 77.9% (vision 0.1 and better) over the follow-up period.

Conclusions:

• Eales' disease requires close monitoring, especially unilateral cases, due to the risk of bilateral progression.
• Fluorescein angiography is crucial for early detection of vascular changes and effective patient management.
• Early intervention and consistent follow-up can lead to improved visual outcomes in Eales' disease.
