[Conjunctival semi-lunar fold nevus of presumed late onset].

Conjunctival nevi are lesions observed commonly occasionnally and can be found later in a life. Such a lesion was observed on the conjunctival semilunar fold in a 76-year-old female patient. It was oval in shape, pigmented, and was mainly visible when the affected eye was in abduction. As no accurate anterior clinical history was available, surgical resection was performed. Hitopathological study disclosed a subepithelial nevus, which was completely resected. Regular follow-up was recommended, as is usual after surgical resection of a conjunctival pigmented tumor.

[Pseudotumoral eyelid inflammation. Apropos of an anatomo-clinical case].

A clinicopathological case of a 76-year-old male patient with a chronic inflammatory change of the inferior left eyelid is reported. The inflammation appeared as a reddish area of the inner part of the eyelid, without sharp limits, but with loss of lashes. Numerous local treatments did not to cure this condition. As some true eyelid tumors may mimic an inflammation during growth and, for example, sebaceous carcinoma may clinically present as chronic unilateral blepharitis, a surgical excisional biopsy was performed on this left eyelid. Its histopathological study showed a granulomatous inflammation, which was typical of a simple chalazion. This case clearly illustrates that the chalazion may not always appear as a limited nodular inflammation of the eyelid, but may have a more diffuse clinical presentation.

[Eyelid neurofibroma affecting a young woman].

A 43-year-old female patient had an amelanotic single tumor thickening the upper right eyelid and observed since early childhood. Clinically, it appeared as a firm mass, without sharp margins, giving a thickened appearance to the superior eyelid. The ophthalmic clinical examination was normal but some subcutaneous nodules attested to the diffusion of the disease recognized as a limited form of neurofibromatosis 1. Although well tolerated, it gave rise to a cosmetic disturbance and the patient was willing to undergo an excision. A complete surgical excision was performed on the lesions and the pathological study disclosed a typical neurofibroma. Regular observation of the different cutaneous nodules was recommended.

[Eyelid precancerous keratosis].

A 25-year-old-male patient had one keratinized tumor on the inferior right eyelid, first observed 5 months before. Its size had been increasing for the last three weeks. The visual function was normal. Clinical examination disclosed a papillomatous lesion on the cutaneous middle part of the eyelid. A surgical excision was performed under local anesthesia. The histopathological study found a papillomatous epidermal proliferation with both structural and cytological atypias, concluding with a precancerous keratosis of the eyelid.

[Bilateral keratoconus: a case report].

Among corneal dystrophies, the keratoconus is one of the most frequently observed among young adults. A clinico pathological case is reported in a 13-year-old-girl of African origin. The diagnosis of bilateral keratoconus was established based on the obvious changes of the corneal curvature and thickness. After an unsuccessful attempt to improve vision with contact lenses, a keratoplasty was finally performed on one side to remove the pathological cornea. Its histopathological study found the characteristic changes of keratoconus: breaks of Bowman's layer and corneal thinning.

[Inflammation of an ectopic pinguecula].

An 80-year-old male patient experienced recently diagnosed swelling of the limbal conjunctiva. In his clinical history were found cataract surgery on the right eye 3 months before, chronic open angle glaucoma effectively treated by local eye drops, treated systemic hypertension and hypercholesterolemia. On ophthalmic examination, a conjunctival mass was present in the inferior lateral conjunctival quadrant next to the limbus, with numerous vessels visible at its top. Treatment with topical corticosteroids failed to obtain regression, but decreased the local inflammatory signs. The persistence of the mass led to its surgical excision under local anesthesia. Histopathology found a subepithelial accumulation of modified collagen bundles typical of elastotic degeneration. Capillary vessels were seen in the superficial subepithelial area, attesting to the high degree of vascularization observed clinically. The final diagnosis was a pinguecula, which was not exactly located on the horizontal meridian area as it is usual.

Silicone punctal plug extrusion resulting from spontaneous dissection of canalicular mucosa: A clinical and histopathologic report.

PURPOSE: To report on an uncommon, previously unidentified, progressive silicone punctal plug extrusion. DESIGN: Small, retrospective case series. PARTICIPANTS: Five cases of punctal plug extrusion were identified among a series of 424 consecutive implantations. Histopathologic analysis was obtained in one case. One additional referred case was included in this report. RESULTS: The plugs were completely extruded from the punctal lumen 6 to 14 months after insertion after an otherwise uncomplicated postoperative course. All plugs were retained at the punctal margin by an encircling band of vascularized mucosal tissue originating from the canalicular lumen. The band consisted of connective tissue of canalicular mucosal origin, attached just below the junction of the punctal and canalicular epithelium. Mild mononuclear infiltration was present in the connective tissue component of the punctal region. There was no cytologic or architectural evidence of abnormal epithelium or connective tissue or of pyogenic granuloma. CONCLUSIONS: These observations suggest that progressive lacrimal punctal plug extrusion may relate to mucosal dissection by the plug edges. We speculate that mechanical stress induced by eyelid closure on an improperly sized or placed implant may result in plug tilt. Subsequent epithelial hyperplasia further enhances the tilt, and the sharper edge of the conical bulb promotes separation of the canalicular mucosa from its distal luminal aspect. At the completion of the extrusion, the mucosal surface is separated from its connective tissue base, at a proximal subpunctal level, causing formation of an encircling tissue band.

[Limbal dermoid and Goldenhar syndrome. Report of an anatomoclinical study].

Dysembryoplastic neoplasm, the limbal dermoid is a benign congenital tumor involving the outer coat of the eye. This congenital tumor affected the right eye of a 6-year-old girl. The lesion was typically hemispheric, covered with pink skin, located in the inferior and temporal part of the cornea, and devoid of any major consequences except the cosmetic appearance of the eye. There were no other major abnormalities in the clinical examination but a single skin tag could be observed at the homolateral preauricular area without any visible cutaneous fistula next to it. This additional change allowed us to establish the diagnosis of a minor form of Goldenhar syndrome. This malformative syndrome typically includes several changes: dermoid and/or dermolipoma, preauricular tags and/or cutaneous fistulas in the same area, vertebral abnormalities etc. These findings may be limited to dermoid and cutaneous tags, as in our report. Such changes must be looked for in all limbal dermoids.

[Endonasal dacryocystorhinostomy (DCR) with protected drill].

PURPOSE: To analyze the interest of protected drills to perform endoscopic endonasal DCR. MATERIAL AND METHODS: [corrected] Fifty patients suffering from chronic epiphora were operated successively. None of those patients had had prior nasal surgery. The same surgeons (BF and ER) did the surgical procedure for all the cases. The technical steps were: endoscopic visualization of the middle meatus and evaluation of the anatomic variations of the nose; identification of the lacrymal bag with a 1 mm light in the canaliculus; unciformectomy; the maxillary bone was drilled with a 3.2 mm bit (straightshot Xomed), protected and irrigated; the lacrymal bag was opened by cissors and the flap was pushed in the ethmoid and coagulated. RESULTS: The suction-irrigation system was efficient to clean the surgical site, with a good endoscopic control. The protected bit didn't damage the 4-mm optics and the septal wall mucosa, even in narrow noses. The staightshot bit (Xomed) was tough enough to drill the maxillary bone in only 68 % of the surgical cases. In 28 % the drilling was unsatisfactory and in 4 % it was inefficient. The functional results at 6 month were good in 85 %. There was no difference between normal and narrow noses. CONCLUSION: The concept of protected bits perfectly matches the endoscopic endonasal DCR. The visual comfort and security of the surgical procedure are increased. Short term results are equivalent to external DCR, but are rather inefficient and expensive.

[Is the uncinate process resection the key to endonasal dacryocystorhinostomy?].

Endonasal dacryocystorhinostomy is technically more difficult than the classic method and apparently less rational. The nasal fossa is a variable and potentially dangerous anatomic region. The uncinate process "opens the door" to the middle meatus and covers, in almost all cases, the junction between the lacrymal bone and maxillary concha. A marker almost always found. Uncinate process resection is a natural way to access the lacrymal apparatus. Associated with transillumination of the lacrymal duct, uncinate process resection, is in our opinion, a reliable and, most importantly, reproducible method for an endonasal approach to the lacrymal sac. With resection, endonasal dacryocystorhinostomy becomes a simple, safe and rapid procedure.

[Eyelid and lacrimal abscesses].

Nonspecific eyelid abscesses are rare, whereas periorbital infections occur more frequently. Localisation of a maximum number of inflammatory signs is essential for diagnosis. A superior external localisation suggest dacryoadenitis or infection of a dermal cyst and the end of the eyebrow. An internal canthal localisation would reflect lacrimal disorder. In the adult, the main cause of infection is acute dacryocystitis. After antibiotic and anti-inflammatory drug treatment, dacryocystorhinotomy is necessary to preclude recurrence. In the newborn, bilateral forms of dilatation of the lacrimal sacs can lead to respiratory distress. The treatment of choice is resection of the endonasal pouches.

[Internal transient palpebral inclusion following dacryocystorhinostomy].

The authors report two cases of postoperative lagophthalmos immediately following ab externo dacrycystorhinostomy (DCR). Two female patients, aged 67 and 62 years, underwent under general analgesia for chronic dacryocystitis with mucocele. An inferior surgical approach, sparing the inner canthal ligament was chosen in both cases. Lagophthalmos was observed on the operated side on the first postoperative day. Normal lid occlusion was present on the contralateral side. Impairement of palpebral occlusion was predominant in the nasal portion of the lid fissure. Upon voluntary and reflex blinking, a reduction in the downward movement of the superior lid was observed. This reduction was not as apparent when the patients were asked to produce a forced blink. Lagophthalmos disappeared progressively over 3 postoperative months in both cases. Neither epiphora nor any corneal complications were observed. Lagophthalmos following DCR via an inferior approach is a previously unreported complication and may be related to the disinsertion of the nasal portion of the orbicularis muscle and periosteum at the time of periosteal cleavage. Recovery of normal lid function may be due to reattachment of the periosteum.
