Naso-orbital fractures designate a backward displacement of the bones of the nasoskeletal framework into the interorbital space. This anatomical disruption results in deformities, lacrimal dysfunction, medial canthal deformities, ptosis, blow-out fractures, ocular complication, and most severely, penetration of bony fragments into the anterior cranial fossa. Early and late treatment methods are considered. Restoration of the bony contour of the nose and medial canthoplasty procedures are discussed.

Six cases of adnexal cysticercosis, (1 in the lacrimal gland, 3 orbital, and 2 palpebral) have been reported. In the lacrimal gland it presented as a painless, translucent cyst which closely simulated a simple dacryops. In the orbit, two of the cases presented as an acute abscess in the upper and inner quadrant. However, one of them initially presented and existed as a case of simple ptosis for a period of 8 months. The third orbital case appeared as a painless cyst in the upper and outer quadrant. In the lid the larva presented as a subcutaneous nodule in one case and in the other it was lodged in the orbicularis oculi muscle. The cyst was surgically removed in all cases and the diagnosis was confirmed by histopathological examination. Lodgement of cysticercus cyst in the lacrimal gland and in the orbicularis oculi muscle is reported for the first time.

Fourteen patients with tuberculosis of the orbit and lacrimal gland seen over a period of 20 years have been presented. The majority of them were between the ages of 4 to 15 years. Males were affected twice as frequently as females. Left side was affected four times as frequently as the right side. There were eight patients of periostitis of orbital margin, one patient of dacryoadenitis, three patients of tuberculoma of orbital tissues, and two patients of tuberculoma of maxillary sinus. One patient with periostitis had involvement of the greater and lesser wings of sphenoid in addition to the involvement of upper-outer orbital margin. Two periostitis patients had prolapse of the palpebral portion of the lacrimal gland. The clinical presentation and gross appearance of the tuberculoma of the lacrimal gland was similar to those found in benign mixed tumor. The patients with tuberculoma of orbital tissues presented as pseudotumors. The mimicry of tuberculoma of maxillary sinus to carcinoma has been mentioned. Associated tuberculous lesions were pulmonary in eight patients, cervical lymphadenitis in ten patients, intestinal in one patient, and caries spine in one patient. In two patients the disease developed in the absence of any other tuberculous lesion discovered in the body. The cases were cured by wide surgical removal of all the diseased tissues combined with antituberculous chemotherapy.

The authors describe a patient who had epiphora and lacrimal outflow obstruction associated with proptosis and prolapse of orbital fat into the eyelids. The patient's puncta remained opposed throughout the blink cycle. A bilateral transcutaneous orbital fat decompression was done via upper eyelid crease and lower eyelid infraciliary incisions. Significant extraconal fat was removed. Two months after surgery, the epiphora had completely resolved, and proptosis and eyelid fullness had decreased.

Congenital nasolacrimal duct mucocele is an uncommon condition in the newborn. Prolapse or expansion of the mucocele into the nose may lead to respiratory distress and difficulty in feeding, as newborns are preferential nose breathers. Infants with congenital lacrimal sac distension should be examined for signs of respiratory distress and nasal pathology. In the presence of respiratory distress, nasal examination and imaging studies should be done to ensure the diagnosis of nasolacrimal duct mucocele. If significant respiratory distress exists, endoscopic marsupialization of the nasolacrimal duct mucocele in conjunction with nasolacrimal duct probing by the ophthalmologist and possible insertion of lacrimal drainage tubes should be considered. At our institution the nasolacrimal duct mucocele was expectantly managed in two of three cases. Only one of the three patients manifested a significant degree of respiratory distress and required intervention. Endoscopic marsupialization of the nasolacrimal duct mucocele resulted in complete resolution of the mucocele and improvement in symptoms.

The lateral temporal fullness of the upper eyelid in patients presenting for a blepharoplasty is sometimes due to a prolapse of the lacrimal gland. The operative procedures that attempt to reposition the migrated lacrimal gland have been either dangerous in that they cause a dry-eye syndrome or unsatisfactory in that they have a high rate of recurrence or other complications. A new and different operative approach to a herniated or prolapsed lacrimal gland deals with an extraglandular concept of repositioning the gland that corresponds to the general principles of hernial surgery.

Myasthenia gravis (MG) is a rare complication of allogeneic bone marrow transplantation (BMT). We present the 11th case in the medical literature, a 23-year-old female 100 months post-allogeneic bone marrow transplantation for acute myelogenous leukemia (AML). After discontinuation of immunosuppression for chronic graft-versus-host disease (GVHD) involving skin, gastrointestinal tract and lacrimal glands, the patient developed severe, progressive dysphagia initially attributed to esophageal candidiasis. With the development of muscle weakness, ptosis, and dysphonia the diagnosis of generalized myasthenia gravis was suspected, and confirmed by elevated anti-acetylcholine receptor antibody titer and a positive edrophonium challenge. Prednisone and pyridostigmine produced improvement, and thymectomy was performed without pathologic evidence of thymoma. Recurrent post-operative respiratory distress required transient mechanical ventilation. Twenty-seven months after diagnosis, the patient requires maintenance prednisone to control symptoms of myasthenia gravis. The clinical features of all reported cases of MG post-allogeneic BMT are reviewed, and universal features include an association with decreasing immunosuppression, the presence of other manifestations of chronic GVHD, anti-acetylcholine receptor antibodies, and the absence of an associated thymoma. HLA Cw1, Cw7 and DR2 were identified at frequencies significantly above that expected from HLA antigen prevalance studies, and may be markers for increased risk of developing MG post-allogeneic BMT. No statistically significant associations with HLA A2, B7, B35 or donor-recipient sex mismatch were present. Reinstitution of immunosuppression and standard therapies for myasthenia gravis were effective in the majority of cases. The role of thymectomy in this population remains unclear.

The authors present 3 patients with subconjunctival fat prolapse treated at their oculoplastic unit. Albeit rare, orbital fat is a well-recognized entity, and is described in the literature as being associated with trauma and surgery. The 3 patients reported herein, however, presented with no history of trauma or surgery. This condition is produced by herniation of the intraconal fat between the conjunctiva and the sclera, presumably due to dehiscence of the Tenon's capsule. Differential diagnosis should be made with lacrimal gland ptosis, lacrimal gland tumors, and lymphoid tumors.

A mandibular block injection produced temporary uniocular blindness, total ophthalmoplegia, mydriasis, and ptosis of the eyelid, with diplopia developing as the sight returned. These effects lasted 25-30 minutes. The explanation offered as to the cause of the anaesthetic phenomenon is an intra-arterial injection into the maxillary artery with backflow of anaesthetic solution into the middle meningeal artery. The instantaneous blindness results from the anaesthetic agent being carried into the central artery of the retina through an anastomosis of the ophthalmic and middle meningeal arteries via the recurrent meningeal branch of the lacrimal artery. Although of short duration, the symptoms mimic a more serious carotid artery embolus occluding the ophthalmic artery. Complications of mandibular blocks have been reported in the literature, however total blindness and ophthalmoplegia are extremely rare. This case report highlights an event where individual anatomical variation of the maxillary and middle meningeal arteries has allowed anaesthetic solution to be delivered to an ectopic site.

Rubinstein-Taybi syndrome is a constellation of clinical findings characterized by mental and motor retardation, broad thumbs and broad first toes, typical facies. Ocular and adnexal abnormalities are quite common and include antimongoloid slant of the palpebral fissures, epicanthal folds, congenital obstruction of the lacrimal excretory system, ptosis, strabismus, congenital cataract and congenital glaucoma. The authors describe the case of a 1-year-old male with the Rubinstein-Taybi syndrome associated with unilateral congenital glaucoma. The case emphasizes the importance of detailed complete ocular examinations in patients with Rubinstein-Taybi syndrome, and also highlights the occurrence of ocular abnormalities rarely associated with this disease.
