Resumen
Purpuse: To describe the behavior the time of posterior vitreous detachment in patients exposed to cataract surgery by biomicroscopy, ocular ultrasound and macular optical coherence tomography.
Materials and methods: A descriptive study of case series of 13 patients was conducted in the Fundacion Oftalmologica Nacional from February to July 2015, 12-month follow-up was performed. For 6 visits they underwent best corrected visual acuity and slitlamp examination. Also they underwent ocular ultrasound and macular optical coherence tomography.
Results: The rate of posterior vitreous detachment by biomicroscopy changed from 7.7% in the visit 0 to 38.4% in visits four. DVP rate by ultrasound in the nasal area changed from 92.3% to 76.9%. In the temporal area changed from 84.6% to 76.9%. In the upper area remained 61.5%. In the lower area it was 69.2% and changed to 76.9%. And finally, in the macular area was 53.8% and in the four visit was 76.9%. The OCT PVD rate change from 69.2% to 76.9%.
Conclussion: Cataract surgery accelerate DVP process. There was an increase of DVP by biomicroscopy and OCT. Ultrasound was not consider an effective tool for diagnosing PVD.
