11/85. descemet membrane detachment after viscocanalostomy.PURPOSE: To report a case that developed a large descemet membrane detachment after viscocanalostomy. methods: Case report. A 60-year-old man with primary open-angle glaucoma underwent viscocanalostomy RE. One day after surgery, a small, localized detachment of descemet membrane was present at the operation site. Six months after surgery, he had a large superior descemet membrane detachment involving his visual axis. RESULTS: The descemet membrane remained attached after descemetopexy with sodium hyaluronate and air. Final visual acuity was 20/80, and intraocular pressure was 17 mm Hg without medication. CONCLUSION: Detachment of the descemet membrane should be recognized as a potential complication of viscocanalostomy.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
12/85. Retinal fixation of traumatic retinal detachment with metallic tacks: a case report with 10 years' follow-up.BACKGROUND: Retinal rupture and detachment caused by traumatic ocular perforation has a poor prognosis without extensive repair procedures. The authors describe the phases of treatment of a complex injury in a 21-year-old man with a traumatic retinal rupture in whom metallic tacks were used for retinal fixation. The report does not include histopathology. methods: Observational case report and literature review. The outcome of a 10-year follow-up is evaluated at the latest visit by determining the visual acuity (VA) and by observing the state of retina and tacks. RESULTS: A traumatic retinal rupture with detachment was treated with titanium tacks for retinal fixation. By inserting a total of 13 metallic tacks for the repair of a temporal postequatorial retinal rupture and adjacent retinal detachment a successful outcome was achieved. Two additional operations were performed to reattach the retina of nasal hemisphere in the same eye. One dislodged tack was removed at the final operation. Ten years later, at the last intervention, VA was 12/20 in the injured eye. The retina was completely attached, and the remaining 12 tacks were in place, although six of them were partially pushed up by an encircling band. Proliferative vitreoretinopathy (PVR) was absent, and a relatively narrow circumferential zone of scar tissue adjacent to the row of tacks was visible. The patient occasionally experienced glare in the affected eye, but was otherwise symptom-free. CONCLUSION: Reports of long-term experiences with mechanical retinal refixation with metallic tacks are scarce. Especially in extended use, the tacks are claimed to cause several complications, including PVR. Although modern ophthalmic surgery offers a variety of methods for retinal reattachment, the complexity of the damage caused by trauma may lead to a dead end in refixation attempts. Nevertheless, retinal tacks may represent an adjunctive remedy in complex retinal detachment cases.- - - - - - - - - - ranking = 0.5keywords = visual (Clic here for more details about this article) |

14/85. Tear in the trabecular meshwork caused by an airsoft gun.PURPOSE: To report a case of a tear in the trabecular meshwork caused by an airsoft gun, a toy that propels a plastic bullet. methods: Case report. RESULTS: A 7-year-old Japanese boy sustained an ocular injury to the right eye from an airsoft gun. Ophthalmic examination 1 hour after the injury showed a best-corrected visual acuity in the injured eye of hand motion, corneal abrasion and edema, hyphema, and commotio retinae. gonioscopy 6 days after the injury revealed a tear in the trabecular meshwork as well as an angle recession. Ultrasound biomicroscopy (UBM) strongly suggested that the tear extended into Schlemm's canal. Corneal abrasion and edema, hyphema, and commotio retinae resolved over 10 days, and best-corrected visual acuity improved to 20/15. Two months after the injury, the trabecular meshwork had not healed. CONCLUSION: Airsoft guns can cause a full-thickness tear in the trabecular meshwork, which may contribute to development of late-onset glaucoma. UBM is useful to evaluate the tomographic features of the disrupted trabecular meshwork. The potential force of airsoft guns to cause substantial ocular injuries should be recognized. Wearing ocular protection should be mandatory while playing with airsoft guns.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
15/85. Retinal pigment epithelial tear after transpupillary thermotherapy for choroidal neovascularization.PURPOSE: To describe two patients who developed a retinal pigment epithelial tear after transpupillary thermotherapy for choroidal neovascularization. METHOD: case reports. RESULTS: Retinal pigment epithelial (retinal pigment epithelium) tear developed in 2 (8%) of 25 eyes after transpupillary thermotherapy for occult choroidal neovascularization associated with age-related macular degeneration. In both eyes, the retinal pigment epithelium tear developed between the treatment session and first post-treatment examination. In both eyes, the visual acuity was unchanged, but the complication of retinal pigment epithelium tear may result in decreased visual acuity when transpupillary thermotherapy is performed in an eye with good initial visual acuity. CONCLUSION: retinal pigment epithelium tear appears to occur more frequently after transpupillary thermotherapy for poorly defined choroidal neovascularization than after conventional laser photocoagulation for poorly defined choroidal neovascularization.- - - - - - - - - - ranking = 1.5keywords = visual (Clic here for more details about this article) |
16/85. Retinal pigment epithelial tear with vitreomacular attachment: a novel pathogenic feature.BACKGROUND: The development of tears of the retinal pigment epithelium (RPE) has classically been described with or without choroidal neovascularization (CNV) or after laser treatment. Tangential shear forces within the RPE or CNV are usually considered to cause the dehiscence. methods: Three patients with CNV and spontaneous RPE tear and additional vitreomacular traction were examined by fluorescein angiography (FA), optical coherence tomography (OCT) and kinetic ultrasound. RESULTS: From the pre-tear to the tear stage a sudden decrease in vision was observed. Fluorescein angiographic images demonstrated RPE-tear formation with blocked filling in the area of the contracted RPE and a well-demarcated hyperfluorescence in the bed of the torn RPE. OCT-scans demonstrated vitreomacular traction at the foveal area in all three cases. Kinetic ultrasound revealed vitreous attachments at the optic disc and fovea. CONCLUSION: Magnitude, variation of mechanical forces, and the continuous shear stress of the aged vitreous gel transmitted across vitreoretinal attachments may cause a chronic stimulus to retina and RPE. Vitreomacular traction may contribute to the subsequent formation of RPE tears via mechanical or cell mediator pathways.- - - - - - - - - - ranking = 0.023457722008068keywords = pathway (Clic here for more details about this article) |
17/85. rupture of a radial keratotomy incision after 11 years during clear corneal phacoemulsification.We report a case of rupture of a radial keratotomy (RK) incision that occurred during clear corneal phacoemulsification 11 years after the initial surgery. The RK was done in both eyes for correction of high myopia (>8.0 diopters). This was followed by 2 enhancement procedures at 6 month intervals. The patient presented with diminished vision in both eyes. The diagnosis was nuclear cataract in the right eye, and clear corneal phacoemulsification was done. The intraoperative and postoperative courses were uneventful. Nine months later, clear corneal temporal phacoemulsification was done in the left eye. During surgery, 1 of the radial incisions opened to one third its length. The wound was sutured, and the procedure was completed uneventfully. One month later, best corrected visual acuity was 20/20.- - - - - - - - - - ranking = 0.5keywords = visual (Clic here for more details about this article) |
18/85. Dehiscence of radial keratotomy wounds without globe rupture following explosion injury.PURPOSE: To report a case of explosive trauma to a patient with a history of radial keratotomy (RK), which resulted in multiple wound dehiscences but not globe rupture. methods: A 29-year-old male underwent radial keratotomy 1 year before he sustained facial trauma from a gasoline tank explosion. Corneal abrasions were treated with copious irrigation, topical antibiotics, corticosteroids, and scopolamine. He did not have a ruptured globe in either eye. RESULTS: The incision sites from radial keratotomy had evidence of anterior dehiscence in both eyes. One month following the injury, the patient had corrected visual acuity of 20/20-1 in the right eye and 20/25 1 in the left eye. At that time, the RK wounds were well healed with minimal irregularity over the incision sites. CONCLUSION: This case demonstrates the excellent recovery of visual acuity in a patient with a partial thickness traumatic wound rupture 12 months following radial keratotomy.- - - - - - - - - - ranking = 1keywords = visual (Clic here for more details about this article) |
19/85. A case of isolated posterior capsule rupture and traumatic cataract caused by blunt ocular trauma.An isolated rupture of the posterior capsule that is caused by a blunt ocular trauma has been rarely reported and is usually detected incidentally during surgery for a complicated cataract. We found an isolated posterior capsule rupture on the third day after trauma in a 25-year-old man who was admitted for the treatment of traumatic hyphema and we performed a phacoemusification and anterior vitrectomy with PC-IOL, implantation because of the traumatic cataract which had progressed after the injury. The PC-IOL was implanted safely into the capsular bag without severe enlargement of the posterior capsular rupture. The break seems to function as a capsulotomy which provides a clear visual axis. We report this case with a review of the literatures.- - - - - - - - - - ranking = 0.5keywords = visual (Clic here for more details about this article) |
20/85. Ocular explosion after peribulbar anesthesia.We report 3 cases of globe rupture after peribulbar anesthesia. We discuss the predisposing factors, presenting features, and visual outcome after this complication. Globe explosion is a severe complication of inadvertent intraocular injection during peribulbar anesthesia. Visual outcome after vitrectomy is generally poor; however, cases that do not develop a retinal detachment may achieve good results.- - - - - - - - - - ranking = 0.5keywords = visual (Clic here for more details about this article) |
