1/137. Irreversible corneal decompensation in patients treated with topical dorzolamide.

    PURPOSE: To describe irreversible corneal decompensation after topical dorzolamide hydrochloride (Trusopt; Merck and Co, Inc, West Point, pennsylvania) therapy in nine patients who had histories consistent with corneal endothelial compromise. METHOD: Multicenter review of patients' charts. RESULTS: Nine eyes of nine patients developed overt corneal decompensation after starting topical dorzolamide, a condition that did not resolve with drug cessation. This occurred after 3 to 20 weeks (mean, 7.8) of therapy. All nine patients had undergone intraocular surgery. Eight patients had undergone cataract surgery; three were aphakic and three had posterior chamber intraocular lenses. Two patients had anterior chamber intraocular lenses and also had undergone trabeculectomies. Four patients had undergone penetrating keratoplasties, each case complicated by episodes of corneal allograft rejection that were successfully treated. Two patients had asymptomatic Fuchs endothelial dystrophy. Seven patients have since undergone successful penetrating keratoplasties. CONCLUSION: The reports suggest that dorzolamide can cause irreversible corneal edema in a subset of glaucoma patients with endothelial compromise. The findings suggest a rationale for research into the long-term effects of dorzolamide on the corneal endothelium. ( info)

2/137. Clinical and histopathologic findings of iris nevus (Cogan-Reese) syndrome.

    PURPOSE: To report a case of Cogan-Reese syndrome. METHOD: Case report. A 37-year-old man presented with Cogan-Reese syndrome. RESULTS: visual acuity was 0.5 in the right eye and 1.0 in the left eye. There were corneal edema and pigmented nodules on the anterior surface of the iris, iris atrophy and ectropion uvea in the right eye. The intraocular pressure was 42 mmHg in the right eye and there was glaucomatous optic atrophy of the optic disk. trabeculectomy with mitomycin C has been performed as the intraocular pressure did not decrease with the maximum medical treatment. Electron microscopic examination of the trabeculum and the iris tissue revealed a lot of melanocytic cells in the stroma. CONCLUSION: trabeculectomy with mitomycin C might be effective in Cogan-Reese cases with glaucoma resistant to medical treatment. ( info)

3/137. herpes simplex virus in the trabeculum of an eye with corneal endotheliitis.

    PURPOSE: To report an eye with corneal endotheliitis and increased intraocular pressure in which the trabeculum demonstrated immunoreactivity for herpes simplex virus. METHOD: Case report. A 62-year-old man presented with increased intraocular pressure, keratic precipitates, and corneal stromal edema in his left eye. The tissue excised during trabeculectomy was immunohistochemically examined for herpetic viruses. RESULT: Immunoreactivity for herpes simplex virus was identified in the trabeculum. CONCLUSION: herpes simplex virus may cause trabeculitis and increased intraocular pressure in patients with corneal endotheliitis. ( info)

4/137. corneal topography of spontaneous perforation of acute hydrops in keratoconus.

    An unusual case of spontaneous corneal perforation of acute hydrops in the left eye of a 21-year-old man is presented. The patient had a history of atopic diseases. To evaluate the status of the other eye, corneal topographic analysis was performed. This confirmed a subclinical keratoconus in the fellow eye and the association with atopy, eye rubbing, and rapid progression of the ectasia leading to perforation. ( info)

5/137. Neurotrophic corneal endothelial failure complicating acute horner syndrome.

    PURPOSE: The authors report the clinical findings of a unique case of rapid corneal endothelial decompensation in association with acute horner syndrome. STUDY DESIGN: Case report and literature review. methods: The authors followed a 38-year-old woman who developed horner syndrome after right jugular vein catheterization during cardiac valvular surgery. Shortly after the operation, horner syndrome accompanied by conjunctival hyperemia and stromal corneal edema developed in the right eye. Over the course of 4 months, the eye became painful, the corneal endothelial cell count dropped precipitously, and the stromal edema worsened, causing a difference of 100 microm in central corneal thickness compared to the unaffected eye. Deep stromal vascularization started at the limbus, resembling interstitial keratitis. RESULTS: A 3-week course of topical steroid treatment resulted in a dramatic improvement in the stromal corneal edema and regression of the deep stromal vascularization. Ocular and right hemicranial pain subsided shortly thereafter. CONCLUSION: The authors hypothesize that corneal endothelial failure in this unique case may have resulted from traumatic sympathectomy. According to experimental evidence in the reviewed ophthalmologic literature, sympathetic innervation may have a neurotrophic role in the cornea. Corneal pathology similar to the authors' case has been described in hemifacial atrophy (Parry-Robson syndrome), a disorder that is assumed to result from sympathetic denervation and that can be produced in animals by cervical sympathectomy. The authors therefore hypothesize that sympathetic denervation of the cornea may rarely cause endothelial decompensation and corneal edema. To the authors' knowledge, this is the first reported case of corneal endothelial failure in horner syndrome. ( info)

6/137. Iridocorneal adhesions in patients with the marfan syndrome.

    marfan syndrome is an autosomal dominant connective tissue disorder characterized by skeletal, cardiovascular, and ocular anomalies. ectopia lentis is the most common ocular manifestation. We report an ocular sign not previously described in marfan syndrome, iridocorneal adhesions secondary to anterior lens subluxation. Three patients with the marfan syndrome had iridocorneal adhesions on slit-lamp examination. One patient developed adhesions following treatment with pilocarpine. She underwent pars plana vitrectomy and lensectomy in both eyes due to progression of the iridocorneal adhesions. Treatment with miotics rotates the lens-iris diaphragm anteriorly and may contribute to the formation of such adhesions. The two other patients remained stable and did not received lensectomy or vitrectomy. Careful slit-lamp examination of the anterior segment should be conducted in patients with dislocated lenses.

7/137. Acute hydrops in the corneal ectasias: associated factors and outcomes.

    PURPOSE: To identify factors associated with the development of hydrops and affecting its clinical outcome. methods: Chart review of all patients with acute hydrops seen by a referral cornea service during a 2.5-year period between June 1996 and December 1998. RESULTS: Twenty-one patients (22 eyes) with acute hydrops were seen. Nineteen patients had keratoconus, 2 had pellucid marginal degeneration, and 1 had keratoglobus. Twenty-one of 22 (95%) eyes had seasonal allergies and 20 of 22 (91%) eyes had allergy-associated eye-rubbing behavior. Six of 22 (27%) had a diagnosis of Down's syndrome. Six patients were able to identify a traumatic inciting event: vigorous eye rubbing in 4 and traumatic contact lens insertion in 2. The affected area ranged from 7% to 100% of the corneal surface area and was related to disease duration and final visual acuity. Proximity of the area of edema to the corneal limbus ranged from 0 to 2.3 mm and was also related to prognosis. Three serious complications were observed: a leak, an infectious keratitis, and an infectious keratitis and coincidental neovascular glaucoma. Various medical therapies did not differ significantly in their effect on outcome, and ultimately 4 (18%) of 22 patients underwent penetrating keratoplasty. Best-corrected visual acuity was equal to or better than prehydrops visual acuity in 5 of the 6 patients in whom prehydrops visual acuity was known, without corneal transplantation. CONCLUSIONS: Allergy and eye-rubbing appear to be important risk factors in the development of hydrops. Visual results are acceptable in some patients without surgery. Close observation allows for the early detection and treatment of complications such as perforation and infection. ( info)

8/137. corneal edema after pediatric cataract surgery.

    INTRODUCTION: We have encountered idiopathic corneal edema in four patients (five eyes) after pediatric lensectomy. This problem has not been previously described in the pediatric ophthalmology literature. methods: Clinical and operative records were reviewed. The children, who ranged in age from 15 months to 6 years, underwent apparently uncomplicated limbal lensectomy without lens implantation. After surgery, all received subconjunctival hydrocortisone (12.5 mg) and 2 to 4 drops daily of topical prednisolone acetate. The corneal edema developed between 2 and 14 days after surgery. RESULTS: The condition cleared in all patients during a 5- to 14-day course of intensive topical steroids. No sequelae have been apparent. Final visual acuities are 20/30 or better in the three children (four eyes) old enough for recognition acuity testing. The fifth eye has excellent central fixation. CONCLUSIONS: We suspect that the corneal decompensation was a manifestation of sterile inflammation. Two of the children had a history of iritis. Difficulty measuring cellular response at the slit-lamp examination and instilling eyedrops at home may have contributed to the complication. Postoperative corneal decompensation can be responsive to topical steroids, which we now prescribe more intensively even in apparently quiet eyes. ( info)

9/137. Air bag-associated ocular trauma in children.

    OBJECTIVE: To describe a series of children with ocular injuries related to air bag deployment. DESIGN: Retrospective, observational case series. PARTICIPANTS: Seven patients with ocular injuries sustained in motor vehicle accidents in which air bags were deployed. methods: review of medical records. RESULTS: All patients had periocular contusions. Minor injuries included corneal abrasions (n = 5), superficial eyelid laceration (n = 1), and traumatic iritis (n = 2). Serious injuries included corneal edema (n = 1) and a traumatic hyphema with secondary glaucoma and cataract (n = 1). The latter patient required surgery. All other injuries resolved with medical therapy. All patients recovered normal visual acuity. CONCLUSIONS: Serious ocular injuries in children may result from air bag deployment. Most such injuries are minor and resolve without sequela. It is recommended that infants and children travel in the rear seat of automobiles to minimize their risk of injury. ( info)

10/137. Intracorneal inclusion of high-molecular-weight sodium hyaluronate following detachment of Descemet's membrane during viscocanalostomy.

    PURPOSE: Viscocanalostomy in accordance with Stegmann's technique is a new surgical option in the treatment of glaucoma. There are few reports available describing the specific complications of viscocanalostomy. We report a case of intracorneal inclusion of high-molecular-weight sodium hyaluronate following viscocanalostomy. CASE REPORT: A 66-year-old man with uncontrolled primary open angle glaucoma of his right eye and a history of argon laser trabeculoplasty underwent viscocanalostomy in accordance with Stegmann's technique. During the filling of Schlemm's canal, a limited lysis of Descemet's membrane advanced centrally in the clear cornea adjacent to the site of canalostomy forming an intracorneal bubble of high-molecular-weight sodium hyaluronate. Postsurgical slit-lamp biomicroscopy showed an intracorneal clear bubble within the corneal periphery without evidence of adjacent corneal edema and with no contact between the corneal endothelium and the iris. Follow-up examinations determined that the appearance of the corneal inclusion, essentially, was unchanged, with only a slight tendency of resorption. No signs of corneal scarring or endothelial decompensation could be noted. CONCLUSION: To date, we could not determine a significant corneal damage in conjunction with the described complication. However, it is difficult to predict the long-term clinical course of our patient. Corneal decompensation as a result of possible endothelial toxicity of high-molecular weight sodium hyaluronate as well as spontaneous absorption seem possible. ( info)
