1/3. Von Willebrand's disease type I as a cause for subvitreal, retinal and subretinal haemorrhages.BACKGROUND: Young patients with vitreous, retinal and subvitreal haemorrhages without neovascularisation or prior trauma are a diagnostic challenge for the physician. In this case report, a patient is presented who developed unilateral, spontaneous, subvitreal, retinal and subretinal haemorrhages and was diagnosed with von Willebrand's disease. CASE REPORT: A 33-year-old Caucasian woman presented at our clinic with unilateral subvitreal, retinal and subretinal haemorrhages. The haemorrhages occurred spontaneously without prior trauma, and the patient had no history of prior bleeding complications. Analysis of the coagulation-fibrinolysis system and von Willebrand multimer analysis led to the diagnosis von Willebrand's disease type I. CONCLUSIONS: Spontaneous subvitreal, retinal and subretinal haemorrhages may be associated with coagulation disorders. Especially in young patients, von Willebrand's disease should be considered as a possible cause.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/3. Ultrasound-guided cryotherapy for retinal tears in patients with vitreous hemorrhage.BACKGROUND AND OBJECTIVE: The goal was to utilize ultrasound-guided cryotherapy as an immediate, low-risk, noninvasive, precise method of treating retinal tears obscured by vitreous hemorrhage. patients AND methods: Eleven patients with sudden onset of vitreous hemorrhage were referred for diagnosis and management. ophthalmoscopy with scleral depression was unsuccessful at localizing peripheral retinal tears, and all of the patients were examined with ultrasound using the techniques of standardized echography. The cryoprobe was positioned for cryotherapy using both transverse and longitudinal B-scan approaches following the indentation of the globe as it appeared on the oscilloscope. RESULTS: On follow-up examination after the vitreous hemorrhage cleared, 10 of the 11 tears were examined by ophthalmoscopy and were thought to have been adequately treated. One patient had a retinal detachment after remaining stable for 3 months. Two patients were treated with laser to enhance the cryotherapy seal. One patient was observed by another physician and underwent vitrectomy due to vitreous hemorrhage that persisted 2 months following cryotherapy. After vitrectomy, the physician reported a successful cryotherapy reaction at the treated tear. One final patient in the series required vitrectomy and scleral buckle before the hemorrhage had cleared, and the treatment did not appear to be complete. CONCLUSION: Ultrasound-guided cryotherapy provides a noninvasive, inexpensive treatment alternative for retinal tears obscured by vitreous hemorrhage.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
3/3. endophthalmitis in eyes following vitrectomy.The authors describe two patients who underwent pars plana vitrectomy for nonclearing vitreous hemorrhage. Both patients had severe pain, increased intraocular pressure, and orbital swelling. The anterior chamber became flat in a phakic eye. The infection progressed rapidly, and ultimately evisceration was required in both cases. The presence of a flat anterior chamber in gas-filled, phakic eyes and a severe orbital inflammatory reaction in the early postoperative period should alert the physician to the possibility of endophthalmitis.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
