Pars plana vitrectomy in ocular Behçet's disease

Area of Science:

• Ophthalmology
• Surgical Interventions
• Inflammatory Diseases

Background:

• Behçet's disease is characterized by severe intraocular inflammation.
• Dense vitreous opacities significantly impair vision in affected patients.
• Medical management may be insufficient for controlling severe ocular manifestations.

Purpose of the Study:

• To assess the outcomes of pars plana vitrectomy in Behçet's disease patients.
• To evaluate the impact of vitrectomy on intraocular inflammation frequency.
• To determine the effect on visual prognosis in patients with dense vitreous opacities.

Main Methods:

• Retrospective analysis of nine Behçet's disease patients undergoing pars plana vitrectomy for vitreous opacification.
• Evaluation of indications, postoperative inflammatory episodes, and visual acuity.
• Follow-up duration ranged from 12 to 66 months, with combined lensectomy in cases of complicated cataracts.

Main Results:

• Preoperative visual acuity was hand motions; postoperative acuity improved in five eyes (to counting fingers-0.4).
• No severe postoperative intraocular inflammatory episodes were observed.
• No cases of phthisis bulbi occurred post-surgery.

Conclusions:

• Pars plana vitrectomy demonstrates a beneficial effect on visual prognosis in Behçet's patients.
• Vitrectomy reduced severe intraocular inflammation frequency in patients refractory to maximal medical therapy.
• Further research with larger cohorts is recommended to validate these findings.
