![]() ![]() Myopia, lattice degeneration, inflammation, retinal injury, atopic dermatitis, and posterior vitreous detachment are identified as predisposing risk factors in RRD. It is more common in males than females and can develop at any age but is more frequent in those aged 20–60 years old. The prevalence of RRD ranges from 6.3 to 17.9 per 100,000 subjects annually. Vitreous traction creates a retinal break allowing liquefied vitreous humor to access the subretinal space and separate the pigmented epithelial and sensory retinal layers. Rhegmatogenous retinal detachment (RRD) can cause permanent vision loss. ![]() Additional surgical procedures should be considered to combine with vitrectomy to achieve better surgical outcomes in these patients. Old age, pseudophakic eye, and presence of macular hole were important risk factors for recurrence after total RRD repair. Patients with total RRD had higher recurrence rate and poorer visual outcome after surgery than patients with focal RRD. Old age, pseudophakic eye, and macular hole as the type of retinal break were highly associated with low success rate. The success rate after primary surgery was 75.0% in the total RRD group, which was significantly lower than partial RRD group ( P < .001). The best-corrected visual acuity (log MAR) before surgery and final best-corrected visual acuity after surgery were 2.23 ± 0.45 and 1.88 ± 0.96, which was significantly poorer than in the partial RRD group ( P < .001). In the total RRD group, retinal breaks were located in both superior and inferior parts of the retina, and macular holes and giant retinal tears were frequently found. Pseudophakic eye, ocular trauma, and proliferative vitreoretinopathy (PVR) were significantly associated with a risk of total RRD ( P = .002, P = .003, and P < .001, respectively). The prevalence of total RRD in all cases of retinal detachment was 4.4%. Two groups were compared for clinical characteristics, risk factors, and prognosis. MethodsĪ retrospective chart review was performed on cases of 44 total RRD and an age- and sex-matched 88 partial RRD. In this study, we investigate the clinical characteristics, risk factors, and prognosis of total RRD.

They may appear like cobwebs, dust, or a swarm of insects-or in the shape of a circle or oval, called a Weiss ring. Floaters are most bothersome when near the center of vision and less annoying when they settle to the side of the vision. If PVD is complicated by vitreous hemorrhage, retinal detachment, epiretinal membrane, or macular hole , the flashes and floaters may be accompanied by decreased or distorted vision. Most patients experience floaters and flashes during the first few weeks of a PVD, but in some cases the symptoms are hardly noticeable. Mild floaters in the vision are normal, but a sudden increase in floaters is often the first symptom of PVD.ĭuring PVD, floaters are often accompanied by flashes, which are most noticeable in dark surroundings. ![]()
