Evaluation of Retinal Circulation Times in Rhegmatogeneous Retinal Detachment with SLO

ABSTRACT

This study was designed to evaluate the association between rhegmatogenous retinal detachment and retinal circulation times. We observed retinal circulation times in 30 patients with rhegmatogeneous retinal detachment before and after operation using the scanning laser ophthalmoscope. We measured arm to retina time(ART) and arteriovenous passage time(AVT) before the operations and after(average 2.5 weeks) successful reattachment of detached retina. Preoperative ART and AVP were 13.83 +/- 3.08 see and 2.91 +/- 0.69 see respectively, whereas postoperative ART and AVP were 13.60 +/- 2.99 see and 2.90 +/- 0.63 see in detached areas. There was no statistically significant difference between pre- and post-operative ART and AVP in detached retina(P>0.05). Preoperative ART and AVP in flat retinal area were 13.82 +/- 3.08 and 2.91 +/- 0.69 see respectively. There was no statistically significant difference between flat and detached area preoperatively (P>0.05). No significant correlation was noted between retinal circulation times and rhegmatogeneous retinal detachments by scanning laser ophthalmoscope.
