Dacryoadenitis associated with Acanthamoeba keratitis.

OBJECTIVE: To report the incidence of dacryoadenitis as a symptom associated with Acanthamoeba keratitis. METHODS: We investigated all cases of Acanthamoeba keratitis (20 patients and 21 eyes) diagnosed and treated at Tokyo Dental College, Ichikawa General Hospital, Ichikawa, Japan, between May 1, 1994, and November 30, 2005. We recorded the incidence of dacryoadenitis diagnosed using clinical signs of lacrimal gland swelling and pain on pressure, computed tomography, magnetic resonance imaging, and histopathologic analysis. RESULTS: Eight eyes (38%) of 8 patients had dacryoadenitis simultaneously with Acanthamoeba keratitis. Dacryoadenitis was diagnosed using histopathologic analysis and computed tomography in 1 patient, histopathologic analysis and magnetic resonance imaging in 1, magnetic resonance imaging in 2, and clinical signs alone in 4. Histopathologic examination in 2 patients revealed moderate infiltration of lymphocytes and plasma cells in the lacrimal gland compatible with dacryoadenitis. No Acanthamoeba organisms were found in the lacrimal gland. The standard protocol for Acanthamoeba keratitis was performed without particular treatment of dacryoadenitis in all patients. Lacrimal gland swelling improved after a mean of 10 weeks (range, 4-17 weeks) in conjunction with symptoms of keratitis; however, 1 patient (patient 1) required levator muscle surgery and blepharoplasty for residual ptosis. CONCLUSION: Dacryoadenitis is a clinical finding associated with Acanthamoeba keratitis.

Granulomatous dacryoadenitis caused by Schistosoma haematobium.

An 11-year-old boy from Sierra Leone developed a mass in the left lacrimal gland a year after trauma to the left side of the brow. Biopsy of the mass led to the diagnosis of schistosomiasis caused by Schistosoma haematobium, which had not been suspected previously. The initial occurrence in the orbit of such a rare, ectopic lesion in schistosomiasis and the possible relationship to previous trauma are features of special interest.

Radiological and histological findings of the lacrimal passages of newborns.

By means of postmortem dacryocystograms and photomicrographs of histological slides, the topography and morphology of the lacrimal passages in premature and mature newborn infants are demonstrated. Because of the bends in the course of the lower tear duct, a percentage of probings will fail to effect satisfactory perforation of Hasner's membrane. In most cases the soft texture of this membrane requires no more than syringing under pressure using a hollow probe.

Silica granuloma of eyelid and ocular adnexa.

Seven cases of subcutaneous epithelioid granulomas caused by silica and involving the eyelids and periorbital region are described. Histologically, all cases disclosed epithelioid tubercles and varying numbers of foreign-body-type giant cells, areas of scarring, and birefringent crystals. Light microscopy with polarized readily facilitated visualization of the crystals. Scanning electron microscopy and energy dispersive x-ray analysis clearly established that the crystals were composed of silica in both its pure and combined forms. This study emphasizes the need for examination of all epithelioid granulomas with polarized light. If crystalline foreign bodies are identified, further special techniques should be used for chemical characterization of the crystals.

Standardized echography in the diagnosis of lacrimal drainage dysfunction.

Fifteen patients with symptoms of nasolacrimal duct obstruction were evaluated with B-scan and standardized A-scan ultrasonography. Results were correlated with findings on routine clinical tests of lacrimal drainage function, and echographic findings were confirmed at surgery in all cases. Ten normal lacrimal systems were also examined. In all patients the lacrimal sac and duct were easily visualized as an echolucent defect bounded by the bony lacrimal crests. Abnormal dilatation, diverticuli, and inflammatory exudates were readily detected. Surgically created dacryocystorhinostomy ostia were imaged on both A- and B-scans, as were obstructing membranes seen before surgical revision. Physiologic lacrimal pump failure could not be evaluated, and the exact site of obstruction could not be determined.

Through curettage in the treatment of chronic canaliculitis.

While various techniques have been proposed for the treatment of canaliculitis, there have been no published series that evaluate the efficacy of simple curettage in the treatment of persistent or recurrent canaliculitis. We report the effectiveness of thorough, simple curettage (without canaliculotomy) in 11 patients with chronic canaliculitis. All patients had a history of canaliculitis-related symptoms for a minimum of 6 months and clinically detectable canalicular concretions before initial treatment. Thorough, simple curettage (without canaliculotomy) resolved the chronic canaliculitis in all of the patients. Ten of the 11 patients were cured with a maximum of two sessions of curettage. One patient required three treatments of curettage and silicone intubation for common canalicular narrowing to render her free of symptoms. No surgical complications occurred in any of the patients. Our report confirms the effectiveness and low morbidity of thorough curettage in the treatment of persistent or recurrent cases of canaliculitis.

Intraoperative fluorouracil in endonasal laser dacryocystorhinostomy.

BACKGROUND: Although endonasal laser dacryocystorhinostomy (ELDCR) offers many advantages compared with conventional techniques, postoperative scarring leading to occlusion of the rhinostomy is more common with ELDCR. OBJECTIVE: To investigate whether fluorouracil applied to the rhinostomy site intraoperatively has an effect on the outcome. PARTICIPANTS: We randomly allocated 155 consecutive patients (201 procedures) to a control group and a fluorouracil group. Patients and investigators were masked to the choice of treatment. METHODS: All patients underwent ELDCR. A pledget soaked in isotonic sodium chloride solution or 0.5-mg/mL fluorouracil, randomly allocated by the pharmacy, was applied to the rhinostomy site for 5 minutes at the time of surgery. Patients were followed up for 12 months and their symptoms were assessed at each visit. RESULTS: Among patients followed up for 12 months or longer, ELDCR procedures performed with topical application of fluorouracil to the rhinostomy site were successful in 65 (76%), compared with 52 (63%) for the control group. This was not statistically significant when patients who failed to attend follow-up at or after 12 months were not counted as successfully treated (P =.21, chi(2) test). Even if those who failed to attend for follow-up were counted as successes, the effect of fluorouracil did not reach significance at the.05 level (P =.08, chi(2) test). CONCLUSION: The topical application of fluorouracil failed to increase the patency rates in ELDCR.

Endolacrimal KTP laser-assisted dacryocystorhinostomy.

OBJECTIVE: To describe our experience with potassium-titanyl-phosphate (KTP) laser-assisted dacryocystorhinostomy, controlled via endolacrimal and endonasal endoscopy. The development of miniendoscopes enables endoscopy of the lacrimal drainage system via the lacrimal puncta to visualize the exact site of a stenosis. DESIGN: A case series of 78 patients, with 1-year postoperative follow-up. SETTINGS: A university medical center. PATIENTS: Consecutive sample of 78 adult patients who required surgery for dacryostenosis. INTERVENTION: Endolacrimal use of a KTP laser to perform a bony osteotomy of the lacrimal sac into the nasal cavity. The position for the perforation was controlled by endonasal endoscopy. The procedure was performed under either general or local anesthesia. RESULTS: One year after surgery, 65 (83%) of the 78 patients were free of symptoms. Seven patients experienced intermittent tearing, and 6 had revision surgery because of restenosis. CONCLUSIONS: The success rate of 83% achieved with KTP laser-assisted dacryocystorhinostomy, using miniendoscopes for lacrimal endoscopy to visualize the exact site of obstruction, is better compared with that of prior studies without the use of miniendoscopes (with success rates of 47%-85%). The advantages of this technique are that it is a minimally invasive procedure, requires a short operating time, and avoids use of an external incision.

Nasolacriminal dysfunction.

This investigation describes the normal function of the lacrimal drainage system of the eye. The intent of the presentation is to illustrate by clinical examples and pertinent literature, those alterations of normal function occurring from obstruction, trauma, or neoplasm. Sixty-nine patients with lacrimal dysfunction are included; 19 are offered in detail to illustrate principles of surgical management. It is not within the scope of this discussion to examine any condition which may cause primary hyperlacrimation or hypolacrimation, but to discuss: 1. the role of trauma as a cause of lacrimal drainage dysfunction. 2. the role of surgery in the prevention of lacrimal dysfunction, and 3. the role of surgery in the restoration of function. Among 18 patients with non-traumatic obstruction treated by silicone stenting, previous multiple dilatations treatment was associated with a higher rate of failure than in those patients not previously treated by multiple dilatations. Forty percent of 96 patients with facial fractures of the medial orbit had obstructive nasolacrimal symptoms; 79% of the 96 patients' symptoms cleared spontaneously; 15% required treatment. No incidence of significant iatrogenic trauma (requiring surgical treatment) was found in reviewing 1292 cases of rhinoplasty, rhinoseptoplasty, blepharoplasty, or sinus surgery. Normal function and physiology are reviewed. From the experiences of 69 patients emerge clinically proven methods of surgical management of lacrimal system obstruction. These methods are defined and then compared and contrasted to traditional methods and concepts. When there is disagreement or no consensus, alternate theories are discussed in attempting to explain those clinical conditions which seem to defy accepted principles. This presentation includes cases which have been managed by surgeons other than the author and who have been trained in fields other than otolaryngology. The cases offered in detail have been managed by the author.
