Abstract
Purpose: :
To measure straylight in patients with clinically significant vitreous opacification
Methods: :
Both eyes of 15 subjects with vitreous opacification were included. Full ophthalmologic examination and straylight measurements, using the C-Quant (Oculus GmbH, Germany), were done in all the patients prior surgery. Pars plana vitrectomy using standard 20 and 25 gauge vitrectomy equipment (Alcon, Forth Worth, TX, USA) was performed in all the patients. 3 months after surgery straylight measurements were repeated in the whole sample.
Results: :
The patients in our study had pre-op best corrected visual acuity between 1.0 and 0.8, but all of them had increased pre-operative straylight values if compared to the normal age-matched population.Post-operative patients showed a significant improvement in straylight values even if visual acuity hardly changed, which led to improved quality of vision. Straylight may contribute to surgical decision making, possibly leading to operation on patients with many subjective complaints due to increased straylight but still good visual acuity.
Conclusions: :
Patients with vitreous opacification who underwent pars plana vitrectomy show improved quality of vision, mostly due to decreased straylight values.Straylight measurement is a promising new tool to better understand patients complaints. The straylight meter can contribute to surgical decision making.
