Although epikeratoplasty (epikeratophakia) for aphakia in children has achieved a high degree of success, there remains a significant incidence of complications, some of which may result in removal of the lenticule. We report a 2-year-old child in whom epikeratoplasty was followed by an acute suppurative keratitis, necessitating removal of the epikeratoplasty lenticule. The recipient bed remained scarred following removal of the lenticule with anterior stomal fibrosis, which precluded good vision. We were able to avoid a penetrating keratoplasty by performing a superficial lamellar keratoplasty with a repeat epikeratoplasty that has remained clear.

Corneal subepithelial infiltration resembling adenoviral keratitis developed in two patients with serologic evidence of systemic Epstein-Barr viral (EBV) infection and nondetectable antibody levels for adenovirus (ADV). These cases suggest that EBV is capable of mimicking more commonly recognized corneal infectious disease entities.

The expression of HLA class I and class II antigens in corneas from normal donors and patients with quiescent herpetic keratitis was investigated using specific monoclonal antibodies. Keratocytes from diseased corneas showed aberrant expression of HLA class I and class II (DR, DP and DQ) antigens. The expression of HLA antigens in these corneas was not associated with immune cell infiltrates or viral antigens.

A consecutive series of 14 patients with trigeminal schwannoma managed surgically at the Neurological Institute of New York since 1970 is reported. Nine women and five men (mean age 40 years) were diagnosed following a mean symptom duration of 33 months. Abnormalities of trigeminal nerve function were present in 11 patients on admission examination. Facial pain was a prominent feature in eight patients. Two patients, both with schwannomas arising from the trigeminal root, presented initially with typical trigeminal neuralgia. Additional cranial nerve palsies or cerebellar or pyramidal tract signs were noted in eight patients. The surgical approach to these tumors depends on their anatomical location. Four patients had tumors confined to the middle fossa, three patients had tumors limited to the posterior fossa, and seven patients had both supratentorial and infratentorial components of their tumors. Twenty operative procedures were performed on these patients, resulting in complete extirpation in six patients, nearly complete removal in seven patients, and partial removal in one patient. Adherence of the tumor to the lateral wall of the cavernous sinus or the brain stem precluded total removal. There was one postoperative death. In the immediate postoperative period, abnormalities of cranial nerves controlling the extraocular muscles were common. In general, these deficits were transient; however, some permanent loss of trigeminal nerve function occurred in nine patients. Two patients required tarsorrhaphy for neurotropic keratitis, and two patients underwent cerebrospinal fluid (CSF) shunting procedures for hydrocephalus or for a persistent CSF leak. The follow-up period ranged from 4 to 177 months (mean 47 months). The clinical features, anatomical considerations, and surgical approach to these rare tumors are discussed. A clinical review of 106 additional cases of trigeminal schwannoma, reported in the English literature since 1935, is also presented.

Fusarium is a ubiquitous fungus that commonly colonizes ulcerated, burned, or traumatized skin and may cause keratitis and onychomycosis in healthy hosts. Serious disseminated infection due to Fusarium has been reported with increasing frequency in immunocompromised patients. We describe a bone marrow transplant patient who developed fungal septicemia and disseminated skin nodules due to Fusarium solani. Fusarium should be recognized as a potential cause of deep fungal infection in immunocompromised patients.

Fifty-three patients consecutively admitted to Moorfields Eye Hospital for treatment of suspected microbial keratitis were examined to identify predisposing factors. The principal associations were pre-existing corneal disease (22 patients (41.5%] and contact lens wear (22 patients (41.5%]. In 13 cases (25%) contact lens wear was the only factor in patients with otherwise healthy eyes using contact lenses as an alternative to spectacles. Gram-negative keratitis was more frequent in the lens wearers, with the exception of therapeutic lens users, than in other patients (p = 0.0006) and Pseudomonas aeruginosa caused keratitis in cosmetic soft lens users more frequently (p = 0.001). There was no correlation between lens handling or solution contamination in three extended wear soft-lens users. This implies that some soft-lens wearers may be infected by Gram-negative organisms from environmental sources other than contaminated lens care materials. Gram-negative keratitis is strongly associated with contact lens wear, and the diagnosis must be considered in any contact lens user with an acutely painful red eye.

In a retrospective review from 1972 through 1987 of patients with microbial keratitis, fungal infection occurred in four (4%) of 90 cosmetic or aphakic contact lens wearers and in four (27%) of 15 patients using a therapeutic soft contact lens. Predisposing factors included improper lens care by the refractive lens wearers and a chronic epithelial defect with topical corticosteroid use among the therapeutic lens wearers. The responsible organisms in the refractive lens group were Fusarium solani (two patients) and Cephalosporium and Paecilomyces (one patient each), and in the therapeutic lens group Candida (three patients) and Aspergillus (one patient). Filamentous fungi were more likely to be associated with cosmetic or aphakic lens wear, whereas yeasts were more frequently found with therapeutic lens use.

We assessed the comparative sensitivities of acridine orange and Gram stains in the examination of corneal scrapings using an experimental model of Pseudomonas aeruginosa keratitis. Acridine orange was more sensitive than Gram stain, requiring concentrations of about 10(4) colony-forming units/mg of corneal tissue compared to approximately 10(5) colony-forming units/mg. Our clinical experience with 21 consecutive cases of suspected microbial keratitis showed a similar diagnostic accuracy of acridine orange and Gram stain. Acridine orange accurately predicted culture results in 15 of 21 specimens (71%) compared to a diagnostic accuracy of 62% (13 of 21 specimens) for Gram stain.

We describe a rare syndrome in a Finnish family, in which the father and his two sons are congenitally deaf and also exhibit corneal vascularization, and hyperkeratosis of the skin of the palms, soles, elbows and knees. In addition, all 3 suffer from fungal infections of the skin and nails. We also describe a fourth, sporadic case of a 9-year-old girl with the same disease. The KID (k = keratitis, i = ichthyosis, d = deafness) syndrome is an ectodermal dysplasia that probably arises through mutation, and is transmitted as an autosomal dominant in the family described by us.

A total of 16/206 eyes in 14/186 patients developed irreversible immune reactions. 15 of the rejected eyes belonged to the 'classical' risk groups, i.e. systemic immune disorders (3/3), metaherpetic keratitis (6/41), pseudophakic bullous keratopathy with inflammation (2/6), non herpetic keratitis with vessel invasion (1/23) and 3 regrafts not included in these groups (a total of 7/31 regrafted eyes rejected). Only 1 rejection occurred in the low-risk groups: an aphakic eye with bullous keratopathy. Histopathological examination revealed that discs which later developed irreversible immune reactions had invariably been grafted in eyes which had vascular invasion and/or inflammation of the recipient cornea. In all, 55/206 eyes ended up with opaque grafts, i.e. irreversible immune reactions were responsible for about one third to one-quarter of the graft failures in the present material. The irreversible immune reactions in the material must be considered 'minimum values', since possible abortive, torpid immune reactions may have escaped recording.
