Epibulbar molluscum contagiosum.

PURPOSE: To report a case of epibulbar conjunctival nodules from molluscum contagiosum in a patient with atopic dermatitis. METHODS: A 39-year-old man with atopic dermatitis who was treated with oral prednisone was initially examined with ocular itching, foreign body sensation, and conjunctival injection of the right eye and was found to have three discrete conjunctival nodules. Excision of the nodules led to complete resolution of the signs and symptoms. RESULT: Histopathologic examination of the conjunctival specimen disclosed molluscum contagiosum. CONCLUSION: Patients with defective or suppressed cell-mediated immunity are at increased risk of unusual ocular involvement with molluscum contagiosum.

Suction cup/contact lens complications following penetrating keratoplasty.

PURPOSE: Rigid gas permeable (RGP) contact lenses facilitate visual rehabilitation in cases of high or irregular corneal astigmatism following penetrating keratoplasty. A variety of plunger-like suction cup devices are available to assist in the removal of these lenses. METHODS: We report three patients with serious complications associated with the use of a suction cup device for contact lens removal following penetrating keratoplasty. RESULTS: Two patients suffered corneal wound dehiscence following contact lens removal; one contact lens was removed by the patient's spouse and the other was removed by a trained technician. A third patient triggered a graft rejection, and ultimately, graft failure, after a vigorous attempt at lens removal. CONCLUSIONS: Forces generated by suction cup devices during removal of RGP contact lenses are sufficient to cause significant trauma. Contact lenses with an apical clearance fit may augment these forces, with the potential for complications following penetrating keratoplasty.

Infectious keratitis with corneal perforation associated with corneal hydrops and contact lens wear in keratoconus.

BACKGROUND: Corneal perforation is an uncommon complication associated with keratoconus. The first cases of infectious keratitis and corneal perforation associated with corneal hydrops and contact lens wear are reported in two keratoconus patients. METHODS: A retrospective chart review and histopathological examination were carried out. RESULTS: Both patients progressed to corneal perforation and emergency penetrating keratoplasty. One patient cultured Fusarium and the second patient Serratia marcesens. Both patients wore contact lenses against medical advice. CONCLUSIONS: The tear in Descement's membrane, stromal oedema, and epithelial bedewing associated with corneal hydrops results in loss of the epithelial-endothelial barrier of the cornea, creating a conduit for infectious organisms through the cornea. Acute hydrops associated with epithelial keratitis, stromal swelling, and a Descement's membrane tear may be a significant risk factor for infectious keratitis and corneal perforation. Contact lenses should not be worn during an active corneal hydrops owing to the increased risk for severe infectious keratitis and corneal perforation.

Psoriatic corneal abscess.

PURPOSE/METHODS: We examined a patient with psoriasis and stromal infiltrate that was treated with topical corticosteroids. RESULTS/CONCLUSIONS: The patient gradually improved and the stromal infiltrate diminished. The cause of psoriasis and its ocular manifestations remains unknown. A corneal abscess without epithelial infiltration that responds to topical corticosteroid therapy may represent a specific ocular manifestation of psoriasis.

Streptococcal preseptal cellulitis complicated by the toxic Streptococcus syndrome.

BACKGROUND: After decades of decline in the incidence of severe infections secondary to group A streptococci, a dramatic increase in the frequency and severity of infections with these organisms has been reported since 1984, including a "toxic Streptococcus syndrome," resembling staphylococcal toxic shock syndrome. To the authors' knowledge, this entity has never been described after ocular infection. METHODS: In a previously healthy 3-year-old boy, preseptal cellulitis developed secondary to minor trauma to the eyelid, progressing rapidly to hypotension, respiratory distress, and an erythrodermic desquamating rash. Ocular and blood cultures grew group A beta-hemolytic streptococci. Appropriate antibiotic coverage and management of systemic manifestations led to rapid improvement, although necrosis developed in the right upper anterior eyelid, requiring skin grafts. RESULTS: More than 3 years since the incident, the patient is free of infection and has a good cosmetic result after skin grafting and revisions for scarring and adhesions. CONCLUSIONS: Streptococcal preseptal cellulitis is not unusual, particularly after trauma. Ophthalmologists must be aware of the re-emergence of more virulent organisms with increased potential for morbidity and mortality.

Progressive Schnyder's corneal dystrophy.

BACKGROUND: Schnyder's crystalline dystrophy is a central anterior bilateral corneal dystrophy characterized by the deposition of crystals composed of cholesterol and other lipids. This condition classically is described as nonprogressive after childhood, but a series of recent studies following patients over time has challenged this teaching. PATIENTS: The authors present a family pedigree including a patient first reported in 1954 and followed for 25 years with dramatic progression of the corneal condition in a dense, discoid pattern of crystals. Best-corrected visual acuity decreased from 20/30 to 20/80 in both eyes. This patient now has three children, all with typical corneal involvement. RESULTS: Ocular pathologic examination performed on corneal biopsies submitted for light and electron microscopy demonstrated cholesterol deposition consistent with a diagnosis of Schnyder's. CONCLUSION: Schnyder's corneal dystrophy may progress significantly over time. The characterization of this condition as stationary may need to be reconsidered.

Glued-on, rigid gas-permeable contact lens for severe radiation-induced keratitis.

A 68-year-old woman with severe radiation-induced keratoconjunctivitis sicca became progressively unresponsive to conventional medical treatment. Her left eye deteriorated rapidly and required total tarsorrhaphy. In an attempt to stabilize the right eye and preserve some functional vision, we glued a high-Dk rigid, gas-permeable contact lens with tissue-grade cyanoacrylate adhesive to Bowman's membrane. This glued-on contact lens induced rapid and dramatic improvement of the patient's comfort and sight. Recent developments in high-permeability, rigid, contact-lens materials now make artificial replacement of the epithelium a potentially useful treatment for severe ocular surface disease when conventional treatment has failed.

Soemmering's ring support for posterior chamber intraocular lens implantation during penetrating keratoplasty. Changing trends in bullous keratopathy.

BACKGROUND: Changing trends in cataract extractions have resulted in a new category of bullous keratopathy: corneal decompensation after complicated extracapsular cataract extraction. These cases of bullous keratopathy are associated with rupture of the posterior capsule, vitreous loss, and significant intraocular inflammation at the time of the original complicated extracapsular cataract extraction. METHODS: The authors reviewed 14 consecutive cases of penetrating keratoplasty for bullous keratopathy in which posterior chamber intraocular lens implantation was supported by remnants of the posterior capsule and/or Soemmering's ring without suture fixation. All 14 patients had a history of complicated extracapsular cataract extraction with capsule rupture and vitreous loss. RESULTS: All 14 patients had clear, compact grafts without migration of the intraocular lens with a mean follow-up of 12.1 months. Vision improved in 93% of cases, and there was no significant worsening of glaucoma. CONCLUSIONS: Pseudophakic bullous keratopathy after traumatic extracapsular cataract extraction with an anterior chamber intraocular lens and aphakic bullous keratopathy after traumatic extracapsular cataract extraction are two relatively new clinical entities that present new intraocular lens management options. Bullous keratopathy after complicated extracapsular cataract extraction should be recognized as a distinct clinical entity. Intraocular lens implantation into the ciliary sulcus with Soemmering's ring and peripheral capsular support provide the advantages of a posterior chamber intraocular lens without the risk of iris or scleral sutures. The authors predict that bullous keratopathy associated with traumatic extracapsular cataract extraction will become one of the more common indications for penetrating keratoplasty.

Keratoconus associated with floppy eyelid syndrome.

Floppy eyelid syndrome is a recently described entity, which characteristically involves overweight individuals. The characteristic findings are an upper lid that may be readily everted, tarsal laxity, and diffuse papillary conjunctival changes. The cause of floppy eyelid syndrome is believed to be a mechanical disorder due to the eversion of the lids while sleeping. The cause of keratoconus remains uncertain. There are strong proponents to a mechanical etiology for this disease. The authors report five cases of floppy eyelid syndrome with concomitant keratoconus. One patient with bilateral keratoconus had bilateral symmetric floppy eyelid syndrome. The other four patients had asymmetric keratoconus and floppy eyelid syndrome. In all four patients, the keratoconus was significantly worse in the eye with the more severe case of floppy eyelid syndrome. In addition, these four patients all gave a history of sleeping with their head facing predominantly on the side with the floppy eyelid syndrome and keratoconus. Two patients with keratoconus and floppy eyelid syndrome were able to undergo successful contact lens rehabilitation of their keratoconus after treatment of the floppy eyelid syndrome.

Massive suprachoroidal hemorrhage in penetrating keratoplasty.

We studied the frequency of massive suprachoroidal hemorrhage during and after penetrating keratoplasty. Nine cases of intraoperative or immediately postoperative massive suprachoroidal hemorrhage were identified in 830 consecutive patients (1.08%) undergoing penetrating keratoplasties at the Manhattan Eye, Ear, and Throat Hospital over a 2 1/2-year period. Six of the nine patients had atherosclerotic disease or hypertension, six of nine patients had glaucoma, and eight of nine patients had undergone previous intraocular surgery. Surgery was performed under general anesthesia in 714 patients, and four of these patients (0.56%) suffered hemorrhages. Five of 116 (4.3%) local anesthesia patients experienced expulsive choroidal hemorrhage. The increased resistance to venous outflow associated with retrobulbar anesthetic injection may significantly contribute to the risk of massive suprachoroidal hemorrhage.

Radial keratotomy. Clinicopathologic case report.

A 36-year-old man underwent radial keratotomy in both eyes to correct mild myopia, with good visual results. The corneoscleral buttons were obtained following the patient's death 17 months after the second procedure and were examined by light, transmission, and scanning electron microscopy. The average depth of the scars was 86.8% of the corneal thickness, and the deeper portions of the wounds healed by fibrous scarring, with no vascularization. The superficial portion of the incision healed by epithelial ingrowth. The average depth of epithelium within the wounds was 25.3% of the corneal thickness. The presence of epithelium in the wounds of radial keratotomy may play a role in decreased wound strength and flattening. The gradual replacement of epithelium by fibrous scarring may be a factor in the regression of corneal flattening.
