Primary ductal adenocarcinoma of the lacrimal gland is an aggressive neoplasm and can be seen either as a de novo malignancy or in the setting of a carcinoma ex pleomorphic adenoma. Carcinoma ex pleomorphic adenoma carries an overall unfavorable outcome; however, prognosis depends on the type and grade of the malignant component, presence of retained myoepithelial component, and extend of invasion beyond the capsule. Herein, the authors describe a 78-year-old man diagnosed with an incidental, intracapsular, high-grade ductal adenocarcinoma in situ ex pleomorphic adenoma, who is free of disease at 9 months subsequent to complete resection. It is important to recognize the morphologic features of intraductal and intracapsular neoplasms to prevent unnecessary morbidities due to extensive surgical interventions or radiotherapy.

A retrospective review of the medical reports of a patient who was undergoing treatment for graft versus host disease following bone marrow transplant for acute myeloid leukemia was conducted. The patient presented with persistent ocular irritation and injection. For an unclear period of time, he developed proptosis and binocular diplopia with limitation of extraocular motility insidiously. MRI revealed gross enlargement of extraocular muscles and bone marrow aspiration trephine confirmed relapse of leukemia. He then underwent chemotherapy with marked improvement of proptosis and extraocular motility. This case report highlights the importance of the eye care provider's careful assessment of patients with a history of malignancy. The presence of ocular irritation must not distract from the detection of other signs. Proptosis and extraocular motility limitation are rarely associated with graft versus host disease. The presence of these signs warrants orbital imaging to rule out recurrence of the primary malignancy.This case report highlights how proptosis and extraocular motility limitation seen in a patient with graft versus host disease may point to recurrence of the primary malignancy.

PURPOSE To describe the clinicopathological features and report the outcomes of treatment in lymphoma involving the extraocular muscles (EOM), the largest reported case-series. METHODS A retrospective case series of patients with lymphoma involving the EOM from a single tertiary referral orbital center, between March 1992 and March 2018. Patients with other histopathologic diagnoses or who did not have an EOM biopsy were excluded. The main outcome measures were histologic evaluation and clinical follow-up including tumor response, recurrence, and survival. RESULTS Twenty-five patients were included, 16 female; 9 male; median age 64.7 years (range 33.8-92.6 years). Unilateral involvement was present in 23 cases (92%). Lymphoma was found to be primary in 15 patients (60%), and any EOM could be affected by disease. Fourteen patients (56%) displayed impaired duction in the direction of the affected muscle. The commonest histologic type was extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue in 16 cases (64%) followed by follicular lymphoma in 3 cases (12%), diffuse large B-cell lymphoma in 2 cases (8%), gamma delta T-cell lymphoma in 2 cases (8%), small lymphocytic lymphom and lymphoplasmacytic lymphoma in 1 case each (4%). All 4 patients with high-grade lymphomas (diffuse large B-cell or T cell lymphoma) were found to have systemic disease. Patients were treated with combinations of radiotherapy, chemotherapy, or immunotherapy, with low toxicity. Two patients developed treatment-related complications. With a median follow-up of 26 months (range 3-108 months), there was only 1 recurrence, which was successfully salvaged with Rituximab, and no deaths due to lymphoma. CONCLUSIONS Lymphoma of the EOM is a rare tumor with good response to treatment, few treatment-related complications and low risk of recurrence or mortality.

PURPOSE Myopathic blepharoptoses (ptoses) is a complex group of disorders. To date, no formal categorization scheme has been developed based on associated ocular and systemic findings, genetic fingerprint, treatment, and prognosis for each ptosis in this group. We report a new classification scheme for myopathic ptoses. METHODS Literature review and classification development. RESULTS A new classification scheme of myopathic ptoses includes isolated static myopathic ptosis (congenital ptosis), static myopathic ptosis associated with aberrant innervation and those associated with periocular abnormalities, and progressive myopathic ptoses that affect the levator muscle and other muscle groups in childhood and adulthood. CONCLUSIONS Making the distinction of myopathic ptosis type early will maximize patient outcomes by optimizing surgical and systemic management and facilitating the recruitment of subspecialists to care for patients with these challenging conditions.

PURPOSE Evaluate visual outcomes in relation to time from injury to intervention in patients who undergo lateral canthotomy with cantholysis (LCC) for retrobulbar hemorrhage (RBH). METHODS Retrospective study of patients with orbital compartment syndrome (OCS) secondary to RBH who underwent LCC. OCS due to RBH was defined by a combination of decreased vision, proptosis, resistance to retropulsion, increased intraocular pressure, and relative afferent pupillary defect. Time from injury to intervention and change in visual acuity were calculated, with regression analysis identifying predictors of vision recovery. RESULTS Fifteen participants were included. Three (20%) participants presented with no light perception, 7 (47%) with count fingers (CF) to light perception, and 5 (33%) with better than count fingers vision. All 5 participants who had LCC within 3 hours (twice the standard 90 minutes) gained some vision, and 6 of 10 participants who had LCC after 3 hours recovered some vision. The latest intervention with visual acuity improvement was performed 9 hours postinjury. Of 3 participants who presented with no light perception vision, 1 regained vision to 20/40 (intervention 1.7 hours postinjury), and 2 did not regain any vision (interventions at 5 and 8.7 hours postinjury). Duration from injury to intervention was associated with decreased amount of vision recovery (P = 0.03). CONCLUSIONS Increased time to intervention with LCC was associated with less vision recovery after OCS from RBH. However, over half of participants with intervention more than 90 minutes after injury still showed visual acuity improvement. The authors recommend LCC in all patients who present with OCS regardless of the time since injury.Patients with orbital compartment syndrome may see visual recovery after lateral canthotomy and cantholysis, even if performed outside of the previously accepted 3-hour window.

PURPOSE The aim of this study was to examine the ultrastructural features of the canalicular entrance into the lacrimal sac. METHODS Ten openings of the common canaliculus into the lacrimal sac from 10 lacrimal sacs obtained during a dacryocystectomy were studied. Each of the openings were completely excised with 3-4 mm margins on all sides and transported to the laboratory in 2.5% glutaraldehyde. The analysis was performed using the standard protocols of scanning electron microscopy (SEM). The openings, their edges, canalicular lacrimal sac-mucosal folds, and internal surfaces were studied. RESULTS Of the 10 common canalicular openings studied, the upper and lower canaliculi opened into a common canaliculus in all the cases. The terminal portion of the 2 canaliculi had a common wall, which appeared like a septum, just proximal to the beginning of the dilated common canalicular portion. In 60% (6/10) of the cases, a diverticular or a type III sinus of Maier (SOM) was noted. The surface of this diverticulum was smooth and lined by stratified columnar epithelium, reflecting its lacrimal sac origins. Interestingly, the junction of the epithelial change from stratified squamous to columnar could be appreciated clearly in 80% (8/10) of the cases and was mostly located just within from the edge of the internal common opening (ICO). The canalicular lacrimal sac-mucosal folds could be appreciated in 70% (7/10) samples, being very defined and prominent in 30% (3/10). CONCLUSIONS The common merged wall of the 2 canaliculus is the most proximal and prominent structure noted on an end-on view of the ICO. Diverticular variant of the sinus of Maier is common. The junction of the epithelial change from stratified squamous to columnar is appreciated just within the edge of the ICO.
