To evaluate the safety and 12-month effect of treatment with pattern scanning laser photocoagulation for ocular surface squamous neoplasia in a low-resource setting with extremely limited access to an operating room. Methods: Adult patients with a clinical diagnosis of ocular surface squamous neoplasia underwent a complete ophthalmologic examination. After topical anesthesia and instillation of toluidine blue 1%, the lesion was treated using pattern scanning photocoagulation for a duration time that varied from 20 to 100 ms and power from 600 to 1,800 mW. Patients were examined on a weekly basis for the first month and underwent weekly retreatment of the remaining lesions, as necessary. Patients had a minimum follow-up of 12 months. Results: Thirty-eight patients (38 eyes) were included. All patients had clinical ocular surface squamous neoplasia that was confirmed by impression cytology. The age of patients ranged from 40 to 83 years (average: 65.5 years) and 28 of them were males (74%). The patients were divided into two groups: group I (immunocompetent) and group II (immunosuppressed). In group I, 23 patients (74%) presented complete response with lesion control after laser treatment alone. In group II, two of seven patients (28%) showed treatment response during the follow-up. The average number of treatments was 2.5 (one to six laser treatments). Procedures were well tolerated. Conclusion: Short-term results of the laser photocoagulation approach for the treatment of ocular surface squamous neoplasia conjunctival lesions were favorable, with a 74% success rate observed in immunocompetent patients. This novel strategy is a less resource-intensive alternative that could demonstrate its usefulness in settings with shortages in operating rooms and in recurrent cases. Studies with longer follow-ups and larger sample sizes are warranted to confirm our findings and evaluate the effectiveness of laser treatment in association with topical chemotherapy.

Introduction:Visually impaired people face many problems when it comes to urban mobility, even though law guarantees their rights. Many of them are able to guide well themselves using white canes and tactile devices, but they still needs some help from the others to successfully complete their journey or assignment, which reduces their autonomy or even their safety. When using public transportation, the visually impaired report lack of awareness and sensitivity of people in general. Improvements of labor field are also important in order to evidence the value of the visually challenged manpower to economy, exercising social inclusion and meliorating their self-esteem. Thus, the idea of a smart city is extremely relevant, because it characterizes progress of infrastructure and services using technology, making city administration, education, public security, health service, housing and transportation even more connected and efficient. The purpose of this study is to show that the combination between concepts related to mobility of unsighted people and to smart cities results in benefits for both the visually impaired and the society.Discussion: Improving visually impaired autonomy in mobility gathering concepts based on smart cities. Conclusion:The fusion of concepts related to visual impairment and smart cities is extremely beneficial for autonomy, mobility and economy.

Introduction: Soccer is the most popular sport in Brazil and worldwide, but there is insufficient data on the eye health of soccer players, and eye conditions may affect the well-being and performance of these athletes. Objective: To perform an ocular evaluation of a representative sample of professional soccer players from Brazil. Methods: This was a cross-sectional study conducted over four consecutive years (2009)(2010)(2011)(2012) at a single professional soccer club in Brazil. The ophthalmology evaluation was performed by the same ophthalmologist in each sample. Prior to the ophthalmology evaluation, all participants filled out a questionnaire to provide the following demographic data: age, position, use of contact lenses or ophthalmic drugs, symptoms, previous ocular surgery, and date of the last ophthalmology evaluation. Visual acuity, intraocular pressure (IOP) and color vision were tested during the ophthalmologic examination, and ophthalmoscopy and biomicroscopy exams were performed. Results: One hundred and twenty bilateral ophthalmology evaluations were performed in 84 professional soccer players between 2009 and 2012. Pinguecula and pterygium were the most common conditions found in the athletes' biomicroscopy exams, corresponding to 63% (38/60) and 17% (10/60) of abnormalities, respectively. In the contrast sensitivity evaluation, only one athlete was color blind. No significant associations were found between the position of the athlete and the results of the biomicroscopy and ophthalmoscopy exams. Conclusion: Despite the high prevalence of abnormalities found in the ophthalmology evaluation, most refractive abnormalities did not require correction, and the biomicroscopy abnormalities were mostly benign. Level III; Study of non-consecutive patients.
