Terms & Conditions of Use

Pars plana vitrectomy for asteroid hyalosis and synchisis scintillans offers limited visual recovery. Cataract surgery and macular pucker were common complications following the procedure.

Area of Science:

Ophthalmology
Retinal Surgery

Context:

Asteroid hyalosis and synchisis scintillans can significantly impair vision.
Pars plana vitrectomy is a surgical option for these vitreous opacities.

Purpose:

To evaluate the effectiveness of pars plana vitrectomy in improving visual acuity for patients with asteroid hyalosis and synchisis scintillans.
To assess complications and visual outcomes following the procedure.

Summary:

A retrospective study of 15 patients (17 eyes) undergoing pars plana vitrectomy for visual decline due to asteroid hyalosis and synchisis scintillans.
Pre-operative vision averaged 20/60, with best post-operative vision reaching 20/40 and final vision stabilizing at 20/50.
Complications included post-operative cataracts (50%), macular pucker (17%), and one macular hole.

Impact:

Pars plana vitrectomy in this cohort yielded suboptimal visual recovery.
Higher incidence of asteroid hyalosis noted in elderly males with vascular risk factors.
Significant rates of secondary cataract and macular pucker necessitate careful patient selection and monitoring.
