Ultra-wide-field autofluorescence imaging in non-traumatic rhegmatogenous retinal detachment.
ABSTRACT PurposeRhegmatogenous retinal detachment (RRD) affects the function of the retina before and after surgical repair. We investigated ultra-wide-field autofluorescence (UAF) abnormalities in patients with acute RRD to improve our understanding of the functional changes in the retina before and after surgery.Methods
In this retrospective study, we present the UAF imaging findings of 16 patients with acute, non-traumatic RRD. Imaging was obtained with the Optos 200 Tx (Optos) in 14 eyes preoperatively and in 12 eyes postoperatively. Twelve eyes had RRDs that involved the macula (group A), whereas four eyes had macula-sparing RRDs (group B).ResultsAll patients (100%) with bullous retinal detachments demonstrated hypofluorescence over the area of retinal detachment. A hyperfluorescent leading edge (HLE) to the retinal detachment was observed preoperatively in 100% of eyes in group A and 75% of eyes in group B. Preoperative UAF through the fovea of group A eyes was normal (30%), hypofluorescent (50%) or hyperfluorescent (20%). In all patients with a HLE preoperatively, the HLE resolved by the 1-month postoperative visit. A residual line of demarcation remained in 8 of the 12 eyes (67%). In group A eyes, postoperative granular autofluorescent changes were present in four of the nine (44%) eyes, and were associated with worse preoperative (P=0.04) and postoperative (P=0.09) visual acuity.ConclusionUAF imaging reveals abnormalities in RRDs that allow excellent demarcation of the extent of the retinal detachment and assist in preoperative characterization of the detachment and postoperative counselling.

ABSTRACT: To evaluate the factors affecting the anatomic success of treatment of retinal detachments (RD) by scleral buckling surgery. One-hundred and two eyes of 102 patients with rhegmatogenous RD operated on by scleral buckling surgery were included in the study. Results were analyzed according to the anatomic status of the retina at the most recent follow-up examination. The chi-squared test was used to determine the relationship between preoperative and intraoperative variables and anatomic results, and the relative risk of failure was determined for each variable. Retinal reattachment was achieved in 85 of 102 eyes (82.5%) after initial surgery. The success rate for anatomic reattachment was 95% after two operations. After three operations reattachment was achieved for 98 eyes (96%). Predictive factors for anatomic failure (P<0.05) were the presence of grade C(1) PVR and multiple breaks. Grade C(1) PVR and multiple breaks were found to be significant risk factors for anatomic failure in rhegmatogenous RD treated by conventional buckling surgery.International Ophthalmology 07/2005; 26(3):77-81.

ABSTRACT: Rhegmatogenous retinal detachment (RRD) may be caused by a flap tear or by an atrophic hole along the lattice degeneration. The aim of this study was to see whether different types of scleral buckling could achieve comparable reattachment rates in eyes with specific types of RRD. 128 eyes with RRD were assigned to receive 1 of 3 buckling procedures according to the following guidelines: retinal detachments caused by flap tears were treated with radial segmental buckling; retinal detachments caused by atrophic holes with limited lattice degeneration were treated with circumferential segmental buckling, and retinal detachments caused by multiple breaks with extensive lattice degeneration were treated with encircling buckling. 56 eyes received radial segmental buckling, 36 eyes received circumferential segmental buckling, and 36 eyes received encircling buckling. The reattachment rates in these three groups were 83.9, 86.1, and 88.9%, respectively (no statistically significant difference). The visual outcomes were comparable in all groups. Younger age, an increased requirement for subretinal fluid drainage, longer operation time, and myopic shift were noted in the encircling group. Comparable reattachment rates could be achieved in all three groups according to our guidelines. Segmental buckling is appropriate for two thirds of RRD in this study and has fewer complications than encircling buckling. Every retinal detachment behaves differently and should be subjected to its optimal buckling procedure to achieve the best results and to avoid unnecessary operative complications.Ophthalmologica 01/2002; 216(1):33-9. · 1.41 Impact Factor

ABSTRACT: To describe the tomographic features of the neurosensory retina after successful rhegmatogenous retinal detachment surgery. Cohort study. We prospectively examined cross-sectional retinal images using optical coherence tomography (OCT) in 15 eyes of 15 consecutive patients (mean age, 46 years) who underwent scleral buckling surgery for treatment of rhegmatogenous retinal detachment. The retinas appeared reattached upon binocular stereoscopic indirect ophthalmoscopy. All eyes were examined at 1, 3, 6, and 12 months postoperatively. The time from onset of subjective symptoms of retinal detachment to retinal surgery ranged from 4 to 66 days (mean, 14 days). The postoperative OCT findings and best-corrected visual acuity were statistically analyzed using the Mann-Whitney U test. The detached retinas appeared attached on ophthalmoscopy in all eyes 1 month postoperatively. OCT showed residual retinal detachment in four eyes (27%) at the fovea and in three eyes (20%) at the fovea and adjacent area. The remaining eight retinas (53%) were attached when examined tomographically. In six of the seven eyes with residual foveal detachment by OCT, the retinas reattached spontaneously up to 12 months postoperatively. The postoperative best-corrected visual acuity improved gradually during 12 postoperative months in all 15 eyes. A substantial increase in visual acuity occurred when the fovea reattached in the six eyes with residual detachment. Foveal retinal detachment may persist after successful retinal detachment surgery in eyes in which the fovea appeared to be attached on ophthalmoscopy. The residual foveal detachment may explain, in part, the delayed visual acuity improvement after successful scleral buckling.American Journal of Ophthalmology 05/2002; 133(4):516-20. · 3.63 Impact Factor
