Purpose To report the phenomenon of spontaneous regression in presumed ocular surface squamous neoplasia (OSSN) Methods Retrospective chart review of clinically diagnosed cases of OSSN during 2016 to 2019 Results Of the 449 OSSN lesions, spontaneous regression was seen in 8 lesions (2%). The mean age at diagnosis of OSSN was 37 years (median, 36 years; range, 21 to 59 years). All were males with unilateral, treatment-naïve tumors. Mean duration of symptoms was 3 months (median, 2 months; range, 1 to 12 months). All tumors arose within the interpalpebral region, located in the nasal quadrant in 88% (n = 7) and in temporal quadrant in 12% (n = 1). The mean tumor diameter was 4 mm (median, 4 mm; range, 3 to 5 mm). Lesions showed nodular (n = 4; 50%) or placoid (n = 4; 50%) morphology. The other features included keratin production and intrinsic vascularity (n = 8; 100%), feeder vessels (n = 4; 50%), and intratumoral pigmentation (n = 4; 50%). The diagnosis of OSSN was confirmed by classic anterior segment optical coherence tomography (AS-OCT) features. Tumors regressed after a mean period of 5 months (median, 4 months; range, <1 to 17 months) from presumed onset and a mean period of 2 months (median, 1 month; range, <1 to 6 months) from presentation to the clinic. No recurrences were noted at a mean follow up of 37 months (median, 35 months; range, 17 to 52 months) after spontaneous regression of tumors. Conclusion OSSN can spontaneously regress in 2% of cases. Immune-mediated reversal of dysplastic changes may explain this phenomenon. Précis In this study, spontaneous regression of presumed ocular surface squamous neoplasia was noted in 2% patients. Tumor regression resulted in restoration of normal epithelial architecture and no recurrences were observed during the follow-up period.

Introduction: Ocular surface squamous neoplasia (OSSN) is the most common nonpigmented ocular surface neoplasm and it can originate from the conjunctiva and/ or corneal epithelium. Since the rate of recurrence after surgical excision is high, chemotherapeutic and immunotherapeutic agents such as interferon alpha-2b (IFN α-2b) have been used for its treatment. Objective: Our objective is to describe the demographic variables of patients with OSSN treated with IFN α-2b and to describe the outcomes of its use in Mexican patients, treated between 2011 and 2017 at Instituto de Oftalmología Fundación Conde de Valenciana. Materials and Methods: This is a non-randomized retrospective interventional case series. We reviewed the files of patients older than 18 years, with clinical and/or histopathological diagnosis of OSSN, treated with IFN α-2b alone or in combination with surgery, with a minimum of 6 months follow-up. We studied demographic variables, such as gender, age, eye affected and associated risks factors; we also studied the type of therapy with interferon (topical, intralesional and/or associated with surgery), time of treatment, time of follow up, recurrences and complications. Results: A total of 39 patients were included. The mean age of diagnosis was 61 ± 16 years and OSSN was more frequent in males (64.1% of cases). Most of the cases (43.6%) had no identifiable risk factors. The mean time of IFN α-2b treatment was 5 ± 2 months, being higher in the intralesional group (6.5 months) than in the topical group (4.2 months). The clinical resolution with the use of IFN α-2b was evidenced between 0.5 and 10 months, being achieved in 87.1% of the patients. Conclusions: The use of IFN α-2b is effective for the treatment of OSSN with a high success rate (87.1%) and a low incidence of relapse (5 cases), with no reported complications during follow up.

Purpose:  This study was conducted to determine the treatment of histologically confirmed ocular surface squamous neoplasia by excision with conjunctival auto graft, and Mitomycin C. Methods: A clinical study of 19 eyes of 19 patients in which excision with conjunctival autograft of ocular surface squamous neoplasia was done and treated with Mitomycin C 0.04% eye drop daily for two to three alternate seven day courses according to the protocol. All patients had weekly follow-up visits till the end of the treatment course, then biweekly visits for three months, and finally monthly visits thereafter. Results: The mean ± SD follow-up period was 39.4±15.3 months (range 06-56 months). Four patients (21.05%) experienced recurrence after the initial treatment; three of them responded to re-treatment and were disease-free, thereafter, till the end of follow-up. Survival analysis with Kaplan-Meier was 94.74%, non-recurrence for 36 months (mean 37.83 months with S.D of 14.73) of follow-up. All patients reported mild to moderate redness and irritation which were controlled with lubricants and mild corticosteroid eye drops. No serious ocular or systemic side effects were seen. Conclusion: Mitomycin C (0.04%) drops used daily for two to three alternate seven day courses were found to be safe and effective with lower recurrence rate for ocular surface squamous neoplasia (OSSN).

Multifocal Recurrence

Corneal ocular surface squamous neoplasia usually begins at the limbus and presents as an avascular translucent sheet over the corneal surface. This case report describes a 67-year-old man with an unusual isolated, keratinous nodular corneal lesion. Slit-lamp examination showed an elevated, avascular, whitish plaque-like lesion at the central cornea surrounded by a normal corneal epithelium, with reduced visual acuity of 20/200 in the right eye. Anterior segment optical coherence tomography displayed a hyper-reflective, thickened epithelium with back shadowing. Histopathology showed keratinising hyperplastic stratified squamous epithelium with parakeratosis and moderate nuclear pleomorphism in lower second/third of epithelium suggestive of moderate dysplasia. His visual acuity returned to 20/20 after surgical excision but he developed multifocal corneal recurrences 6 weeks later, which were successfully managed with seven cycles of topical interferon immunotherapy. There are no recurrences observed at 6 months of follow-up.

Abstract Purpose To observe and describe the anterior segment optical coherence tomography features of limbally localised non-malignant epithelial mass lesions Methods Thirteen patients (age: 66.9 ± 16.3 years) with conjunctival mass suggesting ocular surface squamous neoplasia with biomicroscopic examination were imaged using anterior segment ocular coherence tomography (anterior segment optical coherence tomography)/Cirrus HD-OCT, Model 4000, Carl Zeiss Meditec, Inc., Dublin, CA, and Spectralis HRA + OCT system, Heidelberg Engineering, Vista, CA/. Cases with ocular surface squamous neoplasia-like anterior segment optical coherence tomography (hyperreflective, thickened epithelium and an abrupt transition from normal to abnormal) were included in the study. Maximal thickness of the epithelium was measured. Histological diagnosis was gained from an excisional or incisional biopsy or impression cytology specimens. Results In six patients (age: 68.5 ± 15.4 years) with ocular surface squamous neoplasia-like anterior segment optical coherence tomography features, the histological diagnosis was other than ocular surface squamous neoplasia (papilloma, parakeratosis and a keratotic plaque with mild dysplasia), and ocular surface squamous neoplasia in seven cases (age: 65.6 ± 18.0 years). The maximal epithelial thickness was between 250 and 859 µm in non-ocular surface squamous neoplasia cases and between 252 and 596 µm in ocular surface squamous neoplasia cases. Conclusion Non-malignant epithelial lesions can mimic ocular surface squamous neoplasia on anterior segment optical coherence tomography.

Retrospective Case

Purpose: To describe the risk factors, clinical presentation, management, and outcomes of patients with bilateral ocular surface squamous neoplasia (OSSN). Methods: Retrospective case series. Results: Of the 25 patients with bilateral OSSN, the mean age at diagnosis of OSSN was 31 years (median, 24 years; range, 2–60 years). Risk factors for bilateral OSSN included xeroderma pigmentosum ( n = 15, 60%), human immunodeficiency virus infection ( n = 3, 12%), conjunctival xerosis ( n = 1, 4%), and topical steroid use ( n = 1, 4%). There were no identifiable ocular or systemic risk factors in 7 (28%) patients. Presentation was synchronous in 14 (56%) and metachronous in 11 (44%) patients. Tumor morphology was bilaterally similar in 12 (48%) patients. Histopathological examination ( n = 36) revealed conjunctival intraepithelial neoplasia (CIN) grade 1 in 4 (8%); grade 2 in 7 (14%); carcinoma in situ in 5 (10%), and invasive carcinoma in 20 (40%). Primary management of OSSN ( n = 49) included excisional biopsy ( n = 31, 62%), topical immunotherapy (IFN α2B) ( n = 11; 22%), topical Mitomycin C (MMC) ( n = 3, 6%), enucleation ( n = 1, 2%), orbital exenteration ( n = 2, 4%), and plaque brachytherapy (PBT) ( n = 1, 2%). One patient was lost to follow-up after detection of tumor in the second eye. Recurrent tumors were noted in 16 (32%) eyes and binocular globe salvage was achieved in 16 (64%) patients at a mean follow up of 41 months (median 30 months; range, 1–164 months). Conclusion: OSSN occurrence can be synchronous or metachronous. Meticulous examination of the fellow eye is important for an early diagnosis of OSSN.

Objective: To evaluate the effect of chronicity on the size of the ostium after external dacryocystorhinostomy (DCR) with intubation. Methods: Design: A retrospective chart review of patients who underwent external DCR with intubation over 10 years from January 2003 at a tertiary hospital. All patients were recruited and examined with rigid nasal endoscope. Results: A total number of 66 (85 eyes) patients were included. The mean age at the time of evaluation was 53.1 years with gender distribution of 54 females (81.8 %). The mean duration ±SD between the date of surgery and the date of evaluation was 33.2 ± 33.6 (6–118 months). Our study showed an overall anatomical and functional success of 98.8% and 95.3%, respectively. The mean size of the ostium (±SD) was 23.0 (±15.7) mm2 (ranging from 1 to 80.4 mm2). The size of the ostium was not a significant factor for failure ( p = 0.907). No statistically significant correlation was found between the long-term duration after surgery and the size of the ostium ( R: 0.025, p = 0.157). Conclusions: Nasal endoscopy after DCR is valuable in evaluating the ostium with no observed potential correlation between the long-term follow-up after surgery and the size of the ostium.

PurposeTo investigate the 5-year changes in static and dynamic anterior segment optical coherence tomography (AS-OCT) parameters and their predictors.MethodsThis was a prospective, population-based cohort study of people aged 50 years and older residing in the Liwan District, Guangzhou, China. Standardised AS-OCT scans were performed in November 2008 and November 2013 under dark and light conditions. Customised software was used to analyse horizontal AS-OCT images. Parameters in dark and measurements of light-to-dark changes were used for analyses.ResultsA total of 186 (71.8%) subjects underwent AS-OCT twice, 5 years apart and were included for analyses. The mean age in 2008 was 64.7±7.0 years, and 60.2% were women. The anterior chamber width (ACW) decreased from 11.74±0.44 mm in 2008 to 11.60±0.37 mm in 2013 (p=0.001). There was a trend towards a decrease in dynamic capacity (light-to-dark changes) in the anterior segment, with decreased iris thickness at 750 µm (ΔIT750), ΔACW, Δ anterior chamber area (ACA) and Δ pupil diameter at 5 years (all p<0.05). After adjusting for age and sex, the following baseline parameters were associated with a greater decrease rate in trabecular iris space area at 500 µm (TISA500) at 5 years: TISA500, IT750 and ACA in dark (p<0.001 for all).ConclusionsAnterior chamber angle width decreased and the amount of light-to-dark changes declined during 5-year follow-up. Subjects with greater height, wider angle width and thicker iris at baseline have greater angle narrowing at follow-up.

The diagnostic utility of lower extremity radiographs was evaluated using 84 outpatients 1 to 5 years of age with gait disturbance whose lower extremities appeared physically normal. Chief complaints included limp (65 children [77%]), refusal to walk or stand (37 children [44%]), and frequent falling (6 children [7%]). A total of 43 children (51%) had more than one complaint. The mean age of patients was 26 months and the median duration of symptoms was 1 day. Trauma was reported in 43 (51%) cases and fever in 14 (17%). Results of radiographical studies appeared normal in 81 children (96%), demonstrated soft tissue swelling in 2 children, and revealed a bony island in 1 child. In 1 patient admitted to the hospital for failure to thrive and irritability, and whose radiographic results appeared normal, findings consistent with osteomyelitis later developed. Of the remaining children, 68 (81%) were available for follow-up observation 4 to 28 months after the initial visit and all reported spontaneous resolution of the initial complaint. It was concluded that in a well-appearing child with an otherwise normal physical examination results, an acute gait disturbance is likely to be a self-limiting condition and radiographs are unlikely to contribute to the diagnosis.

Introduction: Atrial fibrillation (AF) is the most common sustained arrhythmia affecting 1-2% of the population. Oral anticoagulation (OAC) reduces stroke risk by 60-80% in AF patients, but only 50% of indicated patients receive OAC. Many patients present to the ED with AF due to arrhythmia symptoms, however; lack of OAC prescription in the ED has been identified as a significant gap in the care of AF patients. Methods: This was a multi-center, pragmatic, three-phase before-after study, in three Canadian sites. Patients who presented to the ED with electrocardiographically (ECG) documented, nonvalvular AF and were discharged home were included. Phase 1 was a retrospective chart review to determine OAC prescription of AF patients in each ED; Phase 2 was a low-intensity knowledge translation intervention where a simple OAC-prescription tool for ED physicians with subsequent short-term OAC prescription was used, as well as an AF patient education package and a letter to family physicians; phase 3 incorporated Phase 2 interventions, but added immediate follow-up in a community AF clinic. The primary outcome of the study was the rate of new OAC prescriptions at ED discharge in AF patients who were OAC eligible and were not on OAC at presentation. Results: A total of 632 patients were included from June, 2015-November, 2016. ED census ranged from 30000-68000 annual visits. Mean age was 71±15, 67±12, 67±13 years, respectively. 47.5% were women, most responsible ED diagnosis was AF in 75.8%. The mean CHA2DS2-VASc score was 2.6±1.8, with no difference amongst groups. There were 266 patients eligible for OAC and were not on this at presentation. In this group, the prescription of new OAC was 15.8% in Phase 1 as compared to 54% and 47%, in Phases 2 and 3, respectively. After adjustment for center, components of the CHA2DS2-VASc score, prior risk of bleeding and most responsible ED diagnosis, the odds ratio for new OAC prescription was 8.0 (95%CI (3.5,18.3) p&lt;0.001) for Phase 3 vs 1, and 10.0 (95%CI (4.4,22.9) p&lt;0.001), for Phase 2 vs 1). No difference in OAC prescription was seen between Phases 2 and 3. Conclusion: Use of a simple OAC-prescription tool was associated with an increase in new OAC prescription in the ED for eligible patients with AF. Further testing in a rigorous study design to assess the effect of this practice on stroke prevention in the AF patients who present to the ED is indicated.

Background: Bronchiectasis is usually caused by pulmonary infections and bronchial obstructions. It is still a serious problem in developing countries, as our country. We reviewed the morbidity and mortal-ity rates and outcomes of bronchiectasis surgical treatment. Patients and methods: Between years 2000 and 2016, one hundred and seven (107) patients, sixty nine (69) of whom female and thirty eight (38) male underwent pulmonary resection for bronchiecta-sis. The mean age was 35years (range, 13–66 years). Mean duration of symptoms was 12 years. Results: Symptoms were copious amount of purulent sputum in 84 patients, expectoration of foul-smelling sputum in 72, haemoptysis in 21 and cough in all patients. The indications for pulmonary resection were: medical therapy failure in eighty two (82) patients, massive haemoptysis in eighteen and lung abscess in seven (7) patients. The disease was bilateral in twenty seven (27) patients and mainly confined in the lower lobe. Eighty six (86) patients had a lobectomy, 7 had a segmentectomy, two patients right pneumonectomy. Operative morbidity was seen in 47 patients (43.9 %) and mor-tality in two (2) patients. Follow-up was complete in 97 patients with a mean of 5 years. Overall, 78 patients were asymptomatic after surgical treatment; symptoms were improved in 24, and unchanged or worse in 5. Conclusions: Surgical treatment of bronchiectasis is more effective in patient with localized disease. It is satisfactory with acceptable ratio of morbidity and mortality.
