Visual Blurring Following Posterior Vitreous Detachment in Fuchs Uveitis Syndrome

Area of Science:

• Ophthalmology
• Vitreoretinal Surgery
• Uveitis Management

Background:

• Fuchs uveitis syndrome (FUS) is a chronic inflammatory condition affecting the eye.
• Posterior vitreous detachment (PVD) is a common age-related condition, but its presentation in FUS patients is less understood.
• Understanding PVD in FUS is crucial for managing visual disturbances and potential complications.

Purpose of the Study:

• To detail the clinical presentation of acute posterior vitreous detachment (PVD) in patients diagnosed with Fuchs uveitis syndrome (FUS).
• To identify diagnostic challenges associated with PVD in the context of FUS.
• To evaluate management strategies and visual outcomes for FUS patients experiencing acute PVD.

Main Methods:

• A retrospective case series was conducted, analyzing consecutive FUS patients who experienced acute PVD.
• Data were collected from patients presenting to a referral center between 2020 and 2024.
• Diagnosis of PVD was confirmed using fundus examination and dynamic B-scan ultrasonography.

Main Results:

• Sixteen eyes of 16 FUS patients (mean age 43 years) presented with acute PVD, reporting sudden blurred vision and floaters.
• Initial best-corrected visual acuity (BCVA) averaged 0.43 logMAR, with B-scan showing echogenic vitreous opacities.
• Spontaneous visual improvement occurred in 62.5% of patients within 3 months (mean BCVA improved to 0.127 logMAR).
• Pars plana vitrectomy (PPV) in three patients with persistent symptoms significantly improved vision (mean logMAR changed from 0.740 to 0.133).

Conclusions:

• Acute PVD in FUS patients causes blurred vision due to inflammatory cell density and vitreous changes.
• While spontaneous visual recovery is common, PPV offers an effective treatment for persistent or severe symptoms.
• This study highlights the importance of recognizing PVD in FUS and considering surgical intervention when necessary.
