1/123. Malignant glaucoma after diode laser cyclophotocoagulation.PURPOSE: To report a case of malignant glaucoma after diode laser cyclophotocoagulation. METHOD: Case report. RESULTS: A 45-year-old man with uncontrolled secondary glaucoma in his right eye after corneoscleral graft and cataract extraction underwent diode laser cyclophotocoagulation. The right eye was aphakic, with an intact posterior capsule. Two weeks later, the patient presented with blurred vision, edematous cornea, and flat anterior chamber. The posterior capsule was touching the endothelium. intraocular pressure was 20 mm Hg. Repeated Nd:YAG laser capsulotomy was effective in reversing the malignant glaucoma attack, and the anterior chamber deepened. CONCLUSION: Malignant glaucoma can occur after diode laser cyclophotocoagulation.- - - - - - - - - - ranking = 1keywords = eye, ocular (Clic here for more details about this article) |
2/123. Unusual intermediate-term outcome in three cases of limbal autograft transplantation.OBJECTIVE: To report an unusual intermediate-term outcome after limbal autograft transplantation for unilateral, severe chemical burns. DESIGN: case reports of three consecutive cases. PARTICIPANTS: Three patients with a history of chemical burns. The fellow eye was clinically uninvolved in all patients. Surgery was indicated for conjunctivalization (cases 1 and 3) and persistent epithelial defect (case 2). INTERVENTION: Three (cases 2 and 3) or four (case 1) 1.25-clock-hour-wide limbal grafts were harvested from the fellow eye and transplanted to the limbus in the affected eye. Surface re-epithelialization, improvement in visual acuity, and maintenance of surface stability were monitored. RESULTS: Limbal grafts were effective in re-epithelialization of the corneal surface within 4 weeks in all cases. Symptomatic relief and improvement in visual acuity were noted during early follow-up. However, a progressive conjunctival ingrowth that tended to override the grafts and encroach the visual axis was noted over the course of a year in all three recipient eyes. CONCLUSIONS: Limbal autograft transplantation is an effective method for surface re-epithelialization in strictly unilateral chemical burns. Caution should be exercised in case selection. The authors' experience suggests a variable degree of attenuation in viability of transplanted limbus. Close follow-up of operated eyes is necessary to determine the long-term efficacy of limbal transplants as a source of corneal phenotypic cells.- - - - - - - - - - ranking = 2.4773920298667keywords = eye (Clic here for more details about this article) |
3/123. Clinical course of phacoemulsification wound burns.PURPOSE: To present 3 cases illustrating the outcomes of phacoemulsification corneal wound burns. SETTING: A university referral center. methods: This was a retrospective case series. RESULTS: Three patients developed corneal wound burns during phacoemulsification of cataract. All eyes developed from 7.00 to 15.00 diopters of astigmatism in the axis of the incision. In 2 eyes, the astigmatism decreased over several months. The third had permanent high astigmatism and corneal edema requiring corneal transplantation. CONCLUSIONS: Corneal wound burns occurring during phacoemulsification can have serious effects on the cornea, including corneal edema and severe astigmatism. In the milder cases, the astigmatism decreases spontaneously over several months.- - - - - - - - - - ranking = 0.9909568119467keywords = eye (Clic here for more details about this article) |
4/123. Cyanoacrylate tissue adhesive augmented tenoplasty: a new surgical procedure for bilateral severe chemical eye burns.PURPOSE: To report on cyanoacrylate tissue adhesive augmented tenoplasty, a new surgical procedure for bilateral severe chemical eye injuries. methods: A 26-year-old man presented with bilateral severe (grade IV) chemical burns involving the eye, periorbital tissues, face, and neck. Despite adequate medical therapy, corneal, limbal, and scleral ulceration progressed in both eyes. Secondary pseudomonas keratitis necessitated therapeutic penetrating keratoplasty in the right eye. Tenoplasty and glued-on rigid gas permeable contact lens were unsuccessful to arrest progression of corneolimboscleral ulceration in the left eye. We applied n-butyl cyanoacrylate tissue adhesive directly on the ulcerating corneal, limbal, and scleral surface to augment tenoplasty. RESULTS: The left ocular surface healed with resultant massive fibrous tissue proliferation and symblepharon on the nasal side. Ocular surface rehabilitation resulted in a vascularized leukomatous corneal opacity with upper temporal clear cornea. The patient achieved visual acuity of 6/36 in the left eye. CONCLUSION: We suggest that cyanoacrylate tissue adhesive-augmented tenoplasty can be undertaken to preserve ocular integrity and retain visual potential in a severe chemical eye injury.- - - - - - - - - - ranking = 5.4683488418134keywords = eye, ocular (Clic here for more details about this article) |
5/123. Limbal transplantation after chemical injuries of the eye.PURPOSE: To illustrate the benefit of limbal stem cell transplantation in three eyes with severe ocular surface failure due to chemical burns. methods: In two patients with monocular corneal scarring and vascularization after chronic chemical burns, a limbal tissue autograft was transferred from the unaffected fellow eye. A complete superficial keratectomy was performed on the host eye. One patient with bilateral ocular surface disorder received an eccentrically trephined corneolimbal allograft. To prevent immunologic rejection of the transplanted limbus, this patient was treated with systemic Ciclosporin A. RESULTS: Postoperatively the limbal autografts grew a normal epithelium on the recipient eye with less vascularization and scarring. Our two patients reported a significant reduction in symptoms (redness, pain, photophobia) and an improved visual acuity. The corneolimbal allograft has remained clear for five months postoperatively. CONCLUSION: In strictly unilateral conditions of limbal deficiency, transplantation of healthy limbal tissue from the normal fellow eye may result in a stable ocular surface and a quiet and comfortable eye. Transplantation of an eccentrically trephined corneolimbal allograft under systemic Ciclosporin A cover may be an option in the rehabilitation of patients with severe bilateral stem cell deficiencies.- - - - - - - - - - ranking = 4.9909568119467keywords = eye, ocular (Clic here for more details about this article) |
6/123. Electric cataract: a case report and review of the literature.A case of electrically induced cataract in both eyes in a 12-year-old boy, after a high-voltage electric shock, is reported. He sustained skin burns on the neck, chest, abdomen, and inner left arm. The cataract developed first in the left eye and later on in the right eye. The child regained normal vision in both eyes after cataract extraction and aphakic correction with spectacles. The need for awareness of the possibility of this complication and screening of all cases of electrical injuries is stressed. The majority of cases respond well to surgery, but final visual acuity will depend on the other ocular damage due to electrical current. The clinical features and pathogenesis of this condition are briefly reviewed.- - - - - - - - - - ranking = 1.9909568119467keywords = eye, ocular (Clic here for more details about this article) |
7/123. Orbicularis oculi myocutaneous flap in reconstruction of postburn lower eyelid ectropion.The management of postburn lower eyelid ectropion is difficult, since the contraction of the skin graft may give rise to secondary deformities especially around the lateral 1/3 of the lower eyelid. In this paper, the results of reconstruction in lower eyelid ectropion with a laterally based orbicularis oculi myocutaneous flap from the upper eyelid in 7 young patients are presented. Satisfactory function and cosmesis were obtained in the evaluation of the patients up to 40 months follow-up. The method proved versatile as the donor scar was well-hidden in the supratarsal fold and the temporally based myocutaneous flap provided additional support to the lower eyelid by exerting an upward pull against the gravity. It is concluded that usage of this flap in postburn ectropion cases is worthwhile to avoid any recurrences. reserved.- - - - - - - - - - ranking = 4.4593056537601keywords = eye (Clic here for more details about this article) |
8/123. Total eyelid reconstruction with free dorsalis pedis flap after deep facial burn.A case of severe facial and corneal burns with complete loss of upper and lower eyelids is reported together with the acute management and surgical options for total eyelid defects secondary to thermal injury. An acutely burned man with 78 percent total burn surface area presented with complete exposure of the left cornea. Because of the severe thermal injury, no facial tissues were available as donor sources for reconstructing the eyelid. A free dorsalis pedis flap was used to cover the exposed cornea after bilateral conjunctival advancement flaps, with septal cartilage graft for structural support. A conjunctivodacryocystorhinostomy was performed at the time of the coverage. The patient was unable to perform an exact visual acuity test; however, his gross vision was intact.- - - - - - - - - - ranking = 3.4683488418134keywords = eye (Clic here for more details about this article) |
9/123. Combined use of an amniotic membrane and tissue adhesive in treating corneal perforation: a case report.We report a new method combining the use of an amniotic membrane and cyanocrylate tissue adhesive to seal a corneal perforation. A 47-year-old male suffered from an alkali injury complicated with corneal melting and perforation in the left eye. We placed an amniotic membrane of optimal size in the anterior chamber directly under the corneal perforation lesion. The cyanocrylate tissue adhesive was then applied over the perforation site and sealed successfully. Three weeks later, the tissue adhesive had dislodged. The amniotic membrane had sealed the perforated lesion and was well adhered to the surrounding corneal tissue with complete epithelial covering. Vision was 20/25 six months after the operation. The combined use of an amniotic membrane and tissue adhesive is a promising method in the treatment of corneal perforation.- - - - - - - - - - ranking = 0.49547840597335keywords = eye (Clic here for more details about this article) |
10/123. Amniotic membrane transplantation for acute chemical or thermal burns.PURPOSE: To determine whether preserved human amniotic membrane (AM) can be used to treat ocular burns in the acute stage. DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: Thirteen eyes from 11 patients with acute burns, 10 eyes with chemical burns and 3 with thermal burns of grades II-III (7 eyes) and grade IV (6 eyes), treated at 7 different facilities. methods: patients received amniotic membrane transplantation (AMT) within 2 weeks after the injury. MAIN OUTCOME MEASURES: Integrity of ocular surface epithelium and visual acuity during 9 months of follow-up. RESULTS: Ten patients were male and one patient was female; most were young (38.2 /- 10.6 years). For a follow-up of 8.8 4.7 months, 11 of 13 eyes (84.63%) showed epithelialization within 2 to 5 weeks (23.7 /- 9.8 days), and final visual acuity improved > or = 6 lines (6 eyes), 4 to 5 lines (2 eyes), and 1 to 3 lines (2 eyes); only one eye experienced a symblepharon. Eyes with burns of grade II to III showed more visual improvement (7.3 /- 3 lines) than those with burns of grade IV (2.3 /- 3.0 lines; P < 0.05, unpaired t test). In the group with grade II or III burns, none had limbal stem cell deficiency. All eyes in the group with grade IV burns did experience limbal stem cell deficiency. CONCLUSIONS: Amniotic membrane transplantation is effective in promoting re-epithelialization and reducing inflammation, thus preventing scarring sequelae in the late stage. In mild to moderate burns, AMT alone rapidly restores both corneal and conjunctival surfaces. In severe burns, however, it restores the conjunctival ocular surface without debilitating symblepharon and reduces limbal stromal inflammation, but does not prevent limbal stem cell deficiency, which requires further limbal stem cell transplantation. These results underscore the importance of immediate intervention in the acute stage of eyes with severely damaged ocular surface. Further prospective randomized studies including a control group are required to determine the effectiveness of AMT in acute chemical and thermal burns of the eye.- - - - - - - - - - ranking = 5.9819136238934keywords = eye, ocular (Clic here for more details about this article) |
