Vitreous Hemorrhage is a common complication of pediatric pars planitis.
Ophthalmology, 2002Co-Authors: Andreas K. Lauer, Joseph E Robertson, Justine R. Smith, James T. RosenbaumAbstract:Abstract Objective To report the prevalence of Vitreous Hemorrhage in pars planitis and to compare the prevalence of Hemorrhage for children and adults with the disease. Design A retrospective, cross-sectional observational study. Participants One hundred eighteen consecutive patients with pars planitis who were evaluated at the Oregon Health and Science University Uveitis Clinic between September 1985 and April 2000. Method A review of clinical records. Main outcome measures For all patients, we recorded presence or absence of Vitreous Hemorrhage, as well as laterality and cause. Children were defined as being age 16 years or younger at diagnosis, and adults were defined as being aged 17 years or older at diagnosis. Results Fourteen percent of patients with pars planitis experienced Vitreous Hemorrhage. Persons with Hemorrhage were significantly younger at the time of disease diagnosis than persons without Hemorrhage ( P = 0.040). The difference in prevalence of Vitreous Hemorrhage between children (28%) and adults (6%) was statistically significant ( P = 0.003). The difference in prevalence of Hemorrhage as a presenting feature between children (20%) and adults (1%) was also statistically significant ( P = 0.001). Conclusions Children with pars planitis are more likely than adults to experience Vitreous Hemorrhage. Pars planitis should be considered in the differential diagnosis of pediatric Vitreous Hemorrhage.

recurrent Vitreous Hemorrhage after sutured posterior chamber intraocular lenses
Retina-the Journal of Retinal and Vitreous Diseases, 2004Co-Authors: Arthur D Fu, Richard H Mcdonald, Michael J Jumper, Thomas M Aaberg, Joseph E Robertson, Robert N Johnson, William E. Smiddy, A I EverettAbstract:Purpose: To describe the clinical course and management of patients with late Vitreous Hemorrhage after scleral suturing of posterior chamber intraocular lenses (PCIOL). Methods: The authors reviewed patient demographics, ocular findings, and clinical course of six patients with late (>3 weeks) Vitreous Hemorrhage after sclera-sutured PCIOL. Intraoperative endoscopy was performed on two patients to better assess the haptic sulcus interaction. Results: Patient age ranged from 39 to 84 years (median 77 years). The interval between scleral suturing of the PCIOL and Vitreous Hemorrhage ranged from 3 weeks to 68 months (median 5 months). The number of Hemorrhages ranged from one to four. The Hemorrhage cleared spontaneously in three eyes. Three patients underwent surgery after the Hemorrhages including sutured PCIOL removal with concurrent placement of an anterior chamber IOL (ACIOL) (two patients) and resuturing of a PCIOL in a different meridian (one patient). Follow-up ranged from 4 to 36 months, median 19.5 months, starting from the time of the initial postsuturing Vitreous Hemorrhage. Final vision ranged from 20/20 to hand motions, with four eyes having 20/40 or better vision. Endoscopy revealed a haptic embedded into the pars plicata in one eye but no evidence of neovascularization. Conclusion: Recurrent Vitreous Hemorrhage may occur as a complication of scleral suturing of PCIOL. The etiology of these Hemorrhages does not appear to be related to neovascular proliferation at the haptic suture site, but may be secondary to erosion of the haptic into uveal structures. Not all eyes require reoperation after these Hemorrhages; however, good visual results may be achieved by replacing the sutured PCIOL with an ACIOL or by suturing the PCIOL in a different meridian.

current management of Vitreous Hemorrhage due to proliferative diabetic retinopathy
International Ophthalmology Clinics, 2014Co-Authors: Jaafar El Annan, Petros E CarvounisAbstract:Diabetic Vitreous Hemorrhage secondary to proliferative diabetic retinopathy is a cause of severe vision loss in diabetic patients. Laser photocoagulation remains the primary treatment when the view allows. IntraVitreous anti-VEGF injections do not appear to have a role as primary treatment but may have an invaluable role as adjuvant to surgery. Pars plana vitrectomy with endolaser panretinal photocoagulation remains the procedure of choice for non-clearing Vitreous Hemorrhage. The vast majority of patients with vision of 5/200 or less due to diabetic Vitreous Hemorrhage do not clear spontaneously even after 1 year. With improvements in surgical techniques leading to better outcomes, fewer complications, less discomfort and a faster recovery time it is reasonable to operate on such patients sooner than the 3–4 months that had been generally accepted in the past, if there has been no significant spontaneous improvement.

Spontaneous and Traumatic Vitreous Hemorrhage
Ophthalmology, 1993Co-Authors: Mohamad-reza Dana, Marc S. Werner, Marlos A. G. Viana, Michael J. ShapiroAbstract:Purpose: The authors sought to provide relevant data regarding the demographic and clinical aspects of spontaneous and traumatic Vitreous Hemorrhages to guide clinicians in better delineating the expected etiologic patterns of these Hemorrhages in an urban environment. Methods: The records of 253 consecutive patients with newly diagnosed Vitreous Hemorrhage seen in a general eye clinic were selected for retrospective analysis. To minimize selection bias of a tertiary care center, patients who were referred to the clinic by outside ophthalmologists for vitreoretinal consultation or those with a history of recent intraocular surgery, postoperative complications, or loss to follow-up were excluded from study. Demographic, ocular, and general medical variables were tabulated for the 200 patients (230 eyes) who met our inclusion criteria. Results: Fifty percent of the patients were black, 26% were white, 23% were Hispanic, and 1% was Oriental. The causes of Vitreous Hemorrhage were proliferative diabetic retinopathy (PDR) (35.2%), trauma (18.3%), retinal vein occlusion (7.4%); retinal tear without a detachment (7.0%), posterior Vitreous detachment (6.5%), proliferative sickle retinopathy (5.7%), retinal tear with a detachment (4.8%), subretinal neovascularization from macular degeneration (2.2%), hypertensive retinopathy (1.7%), unknown (2.5%), and other causes (8.7%). Among black patients with spontaneous Vitreous Hemorrhage, sickle cell retinopathy and retinal vein occlusion were major causes, each accounting for more than 15% of the cases. Systemic hypertension was associated with Vitreous Hemorrhage from retinal vein occlusion. Conclusion: The authors propose that despite the wide array of causative factors of Vitreous Hemorrhage, the evaluation of demographic, ocular, and medical variables can significantly aid clinicians in identifying its etiologic patterns.
