[Results of 35 keratoplasties following corneal injuries].

We have performed 40 keratoplasties in 35 eyes presenting with corneal wounds. These injuries follow accidents of which the most frequent are:--metallic foreign bodies;--windscreen. The following results have been obtained after these grafts;--49 p. 100 success;--51 p. 100 failure. In fact 51 p. 100 of the eyes did not benefit from a satisfactory functional result despite the fact that the graft remained clear in 63 p. 100. Our failures are due to two principle complications: cataract and its subsequent surgical management in 28 out of 35 cases, and detachment of the retina in 3 out of 35 cases. The remaining failures are related to the usual complications of other keratoplasties. These keratoplasties are special since a contussion of the posterior pole is often associated with the corneal wound. The indications for these grafts cannot wait until an accurate assessment of the state of the posterior segment is possible, and this is why these grafts are special and why there should be reservations on the prediction of the final visual result. Keratoplasty however remains the only hope for visual recovery and in children the only means of preventing the development of definite amblyopia. Nevertheless in children the prognosis remains the most pessmistic (4 failures out of 5 cases in children under 10).

Acute corneal injury by mustard gas.

Described is an acute ocular injury caused by mustard gas. The clinical course was similar to what has been established by laboratory research. Some of the histopathologic events have been discussed in theory since no tissue sample from this reported case was available for examination.

Silicone in ophthalmic plastic and reconstructive surgery: a review and laboratory trial.

Silicone is a material with wide application as an exogenous implant in ophthalmic surgery. Animal trials have indicated that extreme care must be taken in the use of this material in the presence of a viable eye. Acute corneal injury was seen in 10 of 14 rabbit eyes tested with a topical application of RTV silicone in the conjunctival cul-de-sac. Two of the 10 eyes demonstrated delayed healing of the corneal injury. Pretreatment with a viscous ocular lubricant, limited corneal contact time of the hardened forms, thorough and frequent corneal evaluation and prompt appropriate treatment of abnormalities are recommended for the successful use of silicone as an orbital molding material in the presence of the viable globe. For use as an orbital expander or as a stent after soft tissue socket reconstruction, despite its relative softness compared to acrylic orbital conformer, similar precautions must be observed to prevent mechanical corneal injuries.

Pseudomonas ulceration of the cornea following major total body burn: a clinical study.

If periorbital or facial areas are involved in burn injury, the eyes must be given prophylactic care. The importance of these cases is not to point out the danger of corneal injury as a direct result of thermal trauma; rather, it is to emphasize the seriousness of corneal abrasions and the danger of subsequent Pseudomonas infection during convalescence of the postburn patient. Once the corneal epithelium is damaged, ulceration rapidly occurs and when infected with Pseudomonas aeruginosa presents one of the most difficult ophthalmologic situations. The convalescent burn patient is in jeopardy of corneal abrasion during general anesthesia for grafting or debridement. Neither of the patients who underwent anesthesia was noted to have corneal abrasion. Nor did either ectropion or lid contracture develop in the three patients described herein. Lid contracture may lead to corneal exposure and should be corrected by expeditious lid tarsorrhaphy. Once ulceration has occurred, as with these patients, corneal transplantation may be indicated.

[Thoughts on a case of perforating flying-stone injury on a 10-year-old boy (author's transl)].

After a left-sided perforating corneal injury caused by a stone, with iris prolaps and wound cataract suffered by a 10-year-old boy, retinal detachment or shrinking of the eye (phthisis bulbi) can occur. On the other hand vision with contact lenses excludes only a few occupations, e.g. in the armed forces, railways, ships etc. The possibility of retirement neurosis (money for suffering!) must also be considered.

[Spontaneous rupture of nylon sutures in the cornea spontaneously (author's transl)].

In 8 patients rupture of nylon sutures in the cornea occurred spontaneously. This happened four times after a corneal cataract extraction, three times after a perforating keratoplasty and once after a perforating corneal injury. The rupture appeared three times 6 1/2 to 7 months after the operation, once after 1 1/2 months. In the other 4 cases the time of rupture is not known. The examination of the nylon sutures with a microscope showed a lamellar-concentric reduction in the straight parts of the sutures and superficial and deep sagittal in the curved parts of the sutures.

Recurrent keratitis due to Acremonium potronii.

In a 15-year-old boy a culture-proved keratitis after a corneal perforation healed without antifungal agents after corneal suturing and application of tissue glue. Eight months later a posterior corneal abscess developed. Diagnostic and therapeutic penetrating keratoplasty was performed when the lesion failed to respond to pimaricin. Cultures were positive for Acremonium potronii, the same fungus isolated from the original corneal laceration eight months previously. To our acknowledge, this is the first case report of a central corneal ulcer or abscess due to this specific organism.

Management and rehabilitation of the facial nerve in parotid surgery.

The facial nerve is the single most important consideration in the surgical management of most parotid disorders. Its surgical anatomy should be well known by the head and neck surgeon. Very few conditions of the parotid gland necessitate the sacrifice of the facial nerve. When this decision is made, the benefits to be derived should be very thoughtfully measured against the tremendous cosmetic and functional sequelae that follow, and the patient should understand preoperatively to the fullest the magnitude of this decision and all its consequences. Most facial nerve deficits resulting from injury or sacrifice of the nerve can be and are best repaired by either direct anastomosis or autografting using a donor sensory nerve. Such restorations of the neuromuscular mechanism yield a physiologic result that is as close to the preinjury state as possible, and this is reflected in cosmetic and functional recoveries that are generally superior to any other of a variety of rehabilitative techniques. In all patients with a paralyzed face, extremely close attention must be given the involved eye to minimize the hazards of corneal injury.

Evaluation of the McCarey-Kaufman technique of corneal storage.

We present our evaluation of the McCarey-Kaufman (M-K) method of corneal storage. Sixty-six rabbit corneas were stored in the M-K medium at 4 C for periods of four, eight, and 12 days. Endothelial viability was assessed, using the specular microscope, the phenomenon of temperature reversal, and known inhibitors of endothelial cell function. Our results support those of McCarey and Kaufman, who showed that rabbit corneas will remain viable when stored by this technique. We were unable to support the contention that M-K medium-stored corneas are functionally superior to those corneas stored in moist chambers in the conventional manner. An unsuccessful attempt was made to correlate the function of the endothelium with either its morphological appearance as seen through the specular microscope or changes in ultrastructure as shown by transmission electron microscopy.

Endocrine influences on ulceration and regeneration in the alkali-burned cornea.

Subconjunctival dibutyryl 3',5' cyclic adenosine monophosphoric acid (DBcAMP) produced a statistically significant reduction of ulceration in the alkaliburned rabbit cornea. No effect on epithelial cell growth was observed. DBcAMP also caused a statistically significant acceleration of corneal neovascularization in the first two weeks postburn. Medroxyprogesterone acetate also affected the development of corneal ulcers postalkali burn, but in a less well-defined manner. Dinoprost and indomethacin did not seem to influence this lesion. Cyclic adenosine monophosphoric acid may therefore possess a potential for use in the alkali-burned human eye.
