Two patients developed corneal opacities resembling infectious crystalline keratopathy. Predisposing factors included a recent corneal transplant with suture replacement in one patient and postradiation keratoconjunctivitis with disposable therapeutic contact-lens wear in the other patient. Both patients were using a topically applied corticosteroid and an aminoglycoside antimicrobial. Smears of corneal scrapings showed numerous yeasts without inflammatory cells. Culturing yielded Candida albicans and Staphylococcus haemolyticus in the first case and C. albicans and S. epidermidis in the second case. Combined antifungal and antimicrobial therapy, with initial withdrawal of corticosteroid use, was effective. The microbial cause of pauci-inflammatory keratitis includes not only viridans streptococci and other bacteria but fungi as well.

We present a case of infectious crystalline keratopathy occurring after 5-fluorouracil filtering surgery. The patient had discrete, branching, white crystalline lesions in the anterior corneal stroma. Cultures grew Streptococcus viridans, and gram-positive cocci were demonstrated in corneal tissue biopsy specimens. Toxic and immunosuppressive properties of 5-fluorouracil may have participated in the pathogenesis of the infectious crystalline keratitis.

In patients with keratitis sicca (exposure keratopathy) in whom treatment with topical tear solutions and ointments is not effective, closure of the lacrimal puncta is performed with insertion of plugs or by cautery, hypercation, or laser. If punctal occlusion fails with these modalities, surgical excision of the canaliculi is recommended. Canaliculectomy successfully relieved ocular irritation and keratopathy in three patients with keratitis sicca, with no complications (follow-up, 10 to 26 months).

Five out of 430 patients (1.16%) undergoing kidney transplantation developed an atypical clinical picture of herpetic dendritic keratitis within four weeks after surgery. It was manifested by multiple dendrites, located mainly in the corneal periphery or the limbus, developing in relatively uninflamed eyes. The response to acyclovir therapy was prolonged and took at least three weeks. Additionally, subepithelial infiltrates with ultimate scarring developed in all patients. Disciform keratopathy was not found. This clinical course is ascribed to the patients' immunosuppressed state.

A retrospective analysis was undertaken of the clinical diagnoses of 1594 eyes that underwent penetrating keratoplasty performed in a private-referral corneal practice over a 9-year period, 1980-1988. The seven most common indications for surgery were keratoconus (24.0%), pseudophakic or aphakic bullous keratopathy (21.2%), corneal scarring (13.9%), Fuchs' endothelial dystrophy (12.5%), regraft (8.1%), and herpetic keratitis (5.3%). Keratoconus was the leading indication from 1980 to 1985. From 1985 to 1988, pseudophakic bullous keratopathy became the leading indication and correlates well with known complications associated with closed-loop anterior chamber lenses, which were widely used during the early 1980s. Less frequent indications for penetrating keratoplasty included the following: infectious (nonviral) keratitis (3.5%); acute or chronic ulcerative keratitis (2.7%); interstitial keratitis (1.8%); mechanical trauma (1.5%); other (non-Fuchs') corneal dystrophies (1.4%); congenital opacities (0.8%); and chemical burns (0.5%).

We describe four patients who, using extended-wear soft contact lenses for myopia, abruptly developed ocular irritation and injection associated with elevated granular opacities initially confined to the central corneal epithelium. Cultures of the granular epithelial lesions were positive for Pseudomonas aeruginosa in all patients. Cultures of the contact lenses and lens case solutions grew Pseudomonas species and other gram-negative organisms. All patients responded to discontinuation of lens wear and frequent topical antibiotics. All recovered baseline visual acuity, and three have successfully resumed contact lens wear. These cases document that Pseudomonas keratitis may be manifested as a granular epithelial keratopathy.

Facial paralysis can result in serious keratopathy because of corneal exposure and inadequate lacrimation. Thirty-seven patients underwent thirty-eight gold weight upper lid implants to rehabilitate paralysis of the eyelid from various causes. When indicated, implantation was combined with lower lid ectropion repair, medial canthoplasty or brow lift. Because of encouraging results in patients with longstanding facial paralysis, "early" implantation (within 1 month of paralysis) was offered to patients with severe lagophthalmos in whom (1) a severe neural injury was documented at the time of transtemporal surgery or (2) delayed, incomplete return of function was expected. Gold weight implantation resulted in excellent eyelid closure, protection, and cosmesis. There were no infections or extrusions. Lagophthalmos and exposure keratitis resolved or were significantly improved in all patients, and most were able to dispense with eyedrops and salves. Visual acuity improved in 95% of patients--a benefit even those without preoperative keratitis often achieved. A mild worsening of one patient's pre-existing astigmatism developed, which resolved after reimplantation with a lighter weight. The implant is easily removed from those patients who, having undergone early implantation, eventually recover adequate function. Gold weight loading has become our procedure of choice for eyelid rehabilitation.

Indications for penetrating keratoplasty (PK) were assessed by clinicopathological review of 659 corneal buttons submitted from 1978 to 1987 to the Ophthalmic Pathology Service in Vancouver. Leading indications for PK were bullous keratopathy (22.2%), keratoconus (17.1%), scarring with or without chronic inflammation (13.5%), graft failure (12.1%), scarring or active keratitis secondary to virus (9.0%) and Fuchs' dystrophy (8.3%). The principal factors responsible for graft failure were also judged by clinicopathological correlation. The authors compare their findings with those in other series.

Corneal affections cause severe ocular morbidity in leprosy. Poor nutrition and low socio-economic status make the eyes prone to repeated secondary infections which makes the pattern of corneal disease in this country different from that reported in western literature. A study of 250 patients shows that leprotic keratopathy has 4 different patterns. Primary leprous keratitis was seen in 56.5% of cases, while secondary leprous keratitis (groups B, C & D) constituted 57.7%. In the latter group the ocular morbidity could be prevented by controlling infection and prevention of concomitant diseases. Cases of lepromatous leprosy showed a consistently higher incidence of different types of corneal involvement than tuberculoid cases.

The authors implanted intraocular lenses (IOL) in 780 eyes and considered complications of this surgery, dividing the complications into intraoperative and postoperative, the latter early and late. The most frequent intraoperative complications were: hyphema, vitreous injury, pupil deformation with an IOL in the anterior chamber (AC), and hyphema and corneal lesions with an IOL in the posterior chamber (PC). Among the early postoperative complications of an IOL in the AC the authors noticed striate keratopathy and uveal flare and postoperative transitory ocular hypertension and striate keratitis with an IOL in the PC. Moreover, in late postoperative complications in AC implantation they observed: cystoid macular edema, bullous keratitis, retinal detachment, late uveitis, opacification of posterior capsule, eccentric displacement of the IOL, and less frequently, cystoid macular edema in PC implantations. The authors prefer IOL implantation in the PC after extracapsular cataract extraction, since this surgery causes less problems in the cornea, vitreous, and retina.
