Macula-Sparing Rhegmatogenous Retinal Detachment: Is Emergent Surgery Necessary?
The status of the macula is a significant factor in determining final visual outcomes in rhegmatogenous retinal detachment (RRD) and should be considered in the timing of surgical repair. Several studies have shown that macula-involving RRDs attain similar visual and anatomic outcomes when surgery is performed within seven days as compared to emergent surgery (within 24 hours). In contrast, sur...
متن کاملOUTPATIENT RETINAL DETACHMENT SURGERY: A PRELIMINARY REPORT
Retinal detachment surgery has been considered an inpatient hospital procedure requiring preoperative and postoperative hospitalization. In this pilot study, outpatient retinal detachment surgery was performed on sixteen patients and the results (100% success rate after an average follow-up of 8.3 months) were comparable or better than reported overall success rates for retinal detachment ...
متن کاملfoveal reattachment following successful surgery for macula-off retinal detachment: deep vitrectomy versus scleral buckling
purpose: to compare deep vitrectomy and scleral buckling for management of macula-off retinal detachment regarding the time course of foveal reattachment. methods: this non-randomized clinical trial included 25 patients with spontaneous rhegmatogenous retinal detachments. patients underwent deep vitrectomy (11 patients) or scleral buckling (14 eyes) based on the accepted indications. patients u...
متن کاملBlood Vessel Segmentation in Retinal Images
Segmentation of blood vessels in retinal images allows early diagnosis of disease; automating this process provides several benefits including minimizing subjectivity and eliminating a painstaking, tedious task. Previous approaches, while satisfactory in some cases, still leave room for improvement, especially in abnormal retinal images. We propose to utilize a tracking based algorithm based on...
متن کاملBlood Vessel Segmentation in Retinal Fundus Images
The segmentation of retinal blood vessels in the retina is a critical step in diagnosis of diabetic retinopathy. In this paper, we present a new method for automatically segmenting blood vessels in retinal images. Five basic algorithms for segmenting retinal blood vessels, based on different image processing techniques, are described and their strengths and weaknesses are compared. A hybrid alg...
