Ocular trauma in childhood was more frequent in the male schoolchild and was due mostly to traumatism with agents like stone, wood and iron pieces, domestic utensils and leisure objects. The injuries occurred most frequently at home. Closed globe injuries predominated. Programs of education and prevention for ocular trauma in childhood are necessary.

All patients were very satisfied with their results. During the course of the study, the authors determined that the ideal candidates for this treatment are young, with thick skin and a definite hollow.

To describe the epidemiological and laboratory characteristics of microbial keratitis at a referral center in Brazil. Charts of all patients referred to the Ocular Microbiology Laboratory at Federal University of São Paulo (UNIFESP) from July 1975 to September 2007 were retrospectively reviewed. The following data were recorded: age, gender, involved eye, use of ocular medication, previous trauma or surgery, contact lens wear and the results of laboratory cultures. The study included 6,804 corneal cultures. The mean age was 42.1 ± 21.4 years. The male-to-female ratio was 1.5:1. Positive cultures were obtained in 3,309 (48.6%) cases. Of these, bacteria were isolated in 2,699 (39.7%), fungi in 364 (5.3%) and Acanthamoeba in 246 (3.6%) samples. Positive bacterial cultures were 2.7-fold more frequent in patients with previous use of steroids (P < 0.01), and a 30% reduction in positive bacterial cultures was observed in patients with previous use of antibiotics (P < 0.01). A total of 1,524 patients (22.4%) had a past history of ocular surgery. Contact lens wearers showed a 1.7 times greater chance of having an Acanthamoeba-positive culture (P < 0.01). Previous ocular trauma was present in 1,118 (16.4%) cases and injury caused by plants showed a 3.8 times greater chance of a positive fungal culture (P < 0.01). Bacterial organisms were identified as the most frequent agent followed by fungi and Acanthamoeba. Prescription of steroids and antibiotics prior to corneal scrapings may modify the laboratory test results. Previous corneal surgery, contact lens wear and ocular trauma have been shown to be risk factors for bacterial, Acanthamoeba and fungal keratitis, respectively.

Purpose: To describe the demographic characteristics, associated factors and causative agents of infectious keratitis in the elderly in a tertiary referral center in São Paulo, Brazil. Methods: A retrospective review of all patients aged 60 years and over with a presumptive diagnosis of infectious keratitis who had material collected for microbiological analysis, between the years 1975 and 2007 (32-year span). Results: From a total of 7,060 age-independent cases of microbial keratitis, 1,545 cases in the elderly were reviewed, which had a mean age of 71.0 ± 7.8 years, ranging from 60 to 101 years. There were 707 males (45.6%) and 838 females (54.3%). Associated factors were: past ocular surgery (25.1%), ocular trauma (7.2%) and contact lens use (3.0%). Bacterioscopy was positive in 40.5% of cases. Culture positivity for any agent was 53.5% (bacteria 47.0%, fungi 6.1%, Acanthamoeba 0.4%). The most frequent bacteria were the grampositive cocci (mostly coagulase-negative Staphylococci) and gram-negative bacilli (mostly the genera Pseudomonas, Moraxella and Proteus), while the most frequent fungi were the filamentous (mostly the genus Fusarium). Conclusions: This study represents a large series of microbial keratitis in the elderly in a single referral center. The most important factor associated with this condition in the elderly was past ocular surgery. The most frequent causative agents were bacteria, especially gram-positive cocci and gram-negative bacilli. Keywords

Upper blepharoplasty causes more postoperative symptoms and presents worse initial aesthetic outcome when the preseptal orbicularis oculi muscle is excised. However, the final aesthetic outcome is the same when the preseptal orbicularis oculi muscle is excised or preserved.

Demodex folliculorum was more prevalent in diabetic patients than in healthy voluntaries, independently of gender and age.

RESUMOA síndrome de frouxidão palpebral é caracterizada pela fácil eversão da pálpebra que ocorre espontaneamente durante o sono causando exposição dos olhos, com consequente conjuntivite papilar crônica. Sua patogênese ainda não está totalmente definida e é mais comum em pacientes masculinos, obesos, de meia idade e está associada a doenças sistêmicas como apnéia obstrutiva do sono, hipertensão arterial e diabetes. Quando o tratamento clínico não apresenta boa resposta, procedimentos cirúrgicos apresentam bons resultados, com técnicas em constante evolução.Descritores: Conjuntiva/patologia; Conjuntivite; Ectrópio; Obesidade/complicações; Hipertensão/complicações; Diabete Mellitus/complicações; Apnéia do sono tipo obstrutiva/complicações; Doenças palpebrais/cirurgia; Síndrome; Músculos oculomotores/cirurgia; Pálpebras/cirurgia; Doenças da córnea ABSTRACTFloppy eyelid syndrome is characterized by the easy evertion of the upper eyelid which occurs spontaneously during the sleep, causing the exposure of the eye surface and chronic papillary conjunctivitis. Its pathogenesis is not totally defined yet: it is usually more frequent in middle-aged, male obese patients and it is associated with systemic disorders such as obstructive sleep apnea, high blood pressure and diabetes. On the occasions which conservative treatment fails, surgical procedures present good results, including surgical techniques which are constantly evolving.
