title: The vascularization process after intravitreal ranibizumab injections for aggressive posterior retinopathy of prematurity

description: ABSTRACT Purpose: To evaluate the retinal vascularization process after intravitreal ranibizumab was administered to infants with aggressive posterior retinopathy of prematurity (AP-ROP). Methods: Twenty-six eyes of 13 infants with AP-ROP who received 0.25 mg intravitreal ranibizumab were retrospectively investigated. The patients were evaluated at weekly follow-up visits, and the findings were analyzed after retinal vascularization was complete. Results: The results showed regression in the AP-ROP of all the patients within the first 48-72 h. Average time for complete vascularization of the nasal quadrant (zone II) was postmenstrual week 45 (range 41-56), and vascularization of the temporal quadrant (zone III) was completed in the postmenstrual week 56 (range 50-65). Reactivation was observed in seven patients, on average at postmenstrual week 42; two of these patients underwent additional treatment. Two patients presented with avascular areas in the peripheral retina despite being 1 year old. Conclusion: These results showed that retinal vascularization following intravitreal ranibizumab was completed after a delay in patients with AP-ROP. Further studies are necessary to evaluate when and how vascularization occurs after intravitreal anti-vascular endothelial growth factor treatments.

title: Frequency of fibromyalgia syndrome in patients with central serous chorioretinopathy

description: ABSTRACT Purpose: To ınvestigate frequency of fibromyalgia syndrome (FMS) among patients with central serous chorioretinopathy (CSCR). Methods: The study included 83 patients with CSCR and 201 age- and sex-matched healthy controls; the mean age was 47.5 ± 11.3 years in the CSCR group (18 women; 21.7%) and 47.2 ± 11.2 years in the control group (44 women; 21.9%). All participants were assessed for FMS based on 2010 American College of Rheumatology diagnostic criteria and for depression and anxiety with the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). Results: FMS was diagnosed in 35 patients (42.2%) from the CSCR group and in 21 individuals (10.4%) from the control group (p&lt;0.001). It was found in 77.77% of the women (14/18) and 32.3% of the men (21/65) in the CSCR group and in 22.7% of the women (10/44) and 7.0% of the men (11/157) in the control group. Familial stress, BDI and BAI scores were higher in the patients with FMS than in those without. When independent risk factors were evaluated by logistic regression analysis, it was found that only the presence of familial stress was a significant risk factor for FMS. Conclusions: Patients with CSCR should be assessed for the presence of FMS, and this should be taken into consideration when developing a treatment plan. Further studies with a larger sample size are needed to clarify the relationship between FMS and CSCR.

title: Translation and validation of the Portuguese version of a dry eye disease symptom questionnaire

description: ABSTRACT Purposes: A symptom questionnaire is an important tool used to quantify and qualify the impact of a disease on a patient's related quality of life and to estimate the prevalence of a certain condition within a population. Ophthalmologists frequently encounter patients with dry eye disease (DED), and therefore, evaluating the symptoms reported by these patients influences diagnosis, therapeutic monitoring, and evaluations of disease progression. The latest consensus on dry eye (Dry Eye Workshop, DEWS), published in 2007, led to the standardization of several questionnaires and a better understanding of the prevalence, severity, and overall effect of DED on the patient's quality of life. Methods: In this study, we translated into Portuguese a symptom questionnaire from DEWS that has already been used in several other population-based studies. For subsequent validation, the translated questionnaire was applied by two independent observers to a population of 30 subjects, and the results were compared in a concordance analysis. Results: The processes of translating to Portuguese and back translating the dry eye symptom questionnaire were conducted without difficulty. The high-correlation coefficients obtained when comparing the results of the initial application and the re-administration of this questionnaire to a sample of 30 individuals indicated excellent concordance with regard to results, repeatability, and reliability. Conclusions: This translated and validated questionnaire can be applied to a larger population with the intent to determine the prevalence of DED symptoms in the overall Brazilian population, as well as in distinct regions of the country.

title: Changes in the conjunctival bacterial flora of patients hospitalized in an intensive care unit

description: ABSTRACT Purpose: To identify the changes in aerobic conjunctival bacterial flora and to correlate culture results with physical health and the duration of patients' hospitalization in an intensive care unit (ICU). Methods: Patients hospitalized in the ICU were included in this study. Conjunctival cultures from all patients were obtained using a standard technique on days 1, 3, 7, and 14. Swabs were plated on nonselective (blood agar) and enriched (chocolate agar) media within one hour. Visible colonies were isolated, and standard microbiological techniques were used to identify the bacteria. The frequency, identity, and correlation of culture results with patients' physical findings and the duration of hospitalization were determined. Results: We obtained 478 cultures (day 1, 270; day 3, 156; day 7, 36; and day 14, 16) from 135 patients; 288 (60.2%) cultures were positive, and 331 microorganisms were isolated. The most frequently isolated microorganism from the cultures was coagulase-negative Staphylococcus species (n=210/331, 63.5%), and the others were Corynebacterium diphtheriae (n=52/331, 15.7%), S. aureus (n=26/331, 7.9%), gram-negative bacilli other than Pseudomonas (n=14/331, 4.2%), Neisseria species (n=8/331, 2.4%), Pseudomonas aeruginosa (n=6/331, 1.8%), Haemophilus influenzae (n=7/331, 2.1%), Acinetobacter species (n=6/331, 1.8%), and Streptococcus species (n=2/331, 0.6%). The frequency of positive cultures significantly increased (p&lt;0.03) with time. Conclusions: Prolonged hospitalization significantly predisposes to bacterial colonization. The colonization rate of S. aureus and Neisseria spp. increased significantly after one week.

title: Tear osmolarity and ocular surface parameters in patients with psoriasis

description: ABSTRACT Purpose: The aim of this study was to evaluate tear osmolarity, tear film function, and ocular surface changes in patients with psoriasis. Methods: At a single center, 30 eyes of 30 patients with psoriasis (group 1) and 30 eyes of 30 healthy individuals (group 2) were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT) test, scoring of ocular surface fluorescein staining using a modified Oxford scale, and tear osmolarity measurement. Results: Tear osmolarity values, OSDI, and Oxford scale scores were significantly higher in group 1 (309.8 ± 9.4 mOsm, 38.9 ± 1.1, and 0.7 ± 1.1, respectively) than in group 2 (292.7 ± 7.7 mOsm, 4.2 ± 0.3, and 0.1 ± 0.3, respectively; p&lt;0.01 for all). TBUT was significantly lower in group 1 (8.7 ± 3.6 s) than in group 2 (18.1 ± 2.8 s; p&lt;0.001). No significant differences were detected in Schirmer I test values between the groups (16.2 ± 2.5 mm in group 1 and 16.6 ± 2.3 mm in group 2; p=0.629). Conclusions: The results of this study showed that psoriasis may influence tear osmolarity and tear film function. Patients with psoriasis showed tear hyperosmolarity and tear film dysfunction.

title: Visual rehabilitation using mini-scleral contact lenses after penetrating keratoplasty

description: ABSTRACT Purpose: To report the visual rehabilitation outcomes and complications of patients fitted with mini-scleral rigid gas-permeable (RGP) contact lenses (mini-SCLs) after penetrating keratoplasty. Methods: We retrospectively reviewed 27 eyes (21 patients) that were fitted with mini-SCLs between October 2013 and December 2014. We analyzed demographic data, previous corneal disorders, visual outcomes, interval from keratoplasty to contact lens fitting, topographic and specular microscope data, fitted contact lens parameters, and complications. The patients were divided into two groups according to the elapsed time since surgery: Group A, grafts with &lt;10 years (n=14 eyes); and Group B, grafts with ≥10 years (n=13 eyes). Results: Lens use was discontinued in four eyes, and microbial keratitis developed in one eye during follow-up. No corneal graft rejection was observed. The mean interval between grafting and initial contact lens fitting was 10.6 ± 7.3 years (range: 1-29 years). The most frequent reason for keratoplasty was keratoconus (22 eyes, 81.4%). The mean contact lens-corrected visual acuity (CLCVA) was 0.09 ± 0.12 logMar (range: 0.50-0.00 logMar). The average topographic astigmatism, mean steepest keratometry (Kmax), and average cellularity on specular microscopy were 6.19 ± 3.49 diopters (D), 58.4 ± 7.8 D, and 1,231 ± 723 cells/mm2, respectively. Conclusions: Mini-SCL use allowed successful visual rehabilitation after corneal keratoplasty, particularly in patients who required corrective lenses for low visual acuity and were unable to wear RGP contact lenses. Our results indicate that mini-scleral lenses may be an option for the treatment of corneal irregularities, such as those associated with keratoplasty.

title: Bilateral retinal vasculitis in a patient with lichen planus

description: ABSTRACT Lichen planus (LP) is an autoimmune, inflammatory disease of unknown etiology that commonly affects the skin and mucous membranes. Retinal vasculitis is a group of vision-threatening disorders, in which autoimmunity is thought to play a role in pathogenesis. We present the case of a patient who was diagnosed with retinal vasculitis and who was followed up for mucosal LP. LP has not been reported as a cause of retinal vasculitis in the literature. We believe that the retinal vasculitis in this case was related to LP because cellular immunity plays a role in the pathogenesis of both entities.

title: Pupilloplasty in a patient with true polycoria: a case report

description: ABSTRACT Here we report a case of surgical pupilloplasty in an adult with true polycoria. A 44-year old man was referred to our clinic with a best-corrected visual acuity (BCVA) of 0.5 diopters (D) in his left eye. Biomicroscopy revealed two pupils within a 2.5-mm central zone, with diameters of 1.2 and 1.1 mm. Both pupils had real iris sphincters and responded to light and chemical stimulation. Therefore, we surgically cut the bridge between the two pupils without any intraoperative or postoperative complications. One month after the surgery, BCVA had improved to 0.9 D, and the final pupil was almost round, measuring 2.7 mm in diameter.

title: Extraconal cystic schwannoma mimicking an orbital dermoid cyst

description: ABSTRACT To our knowledge, we report the first case of an extraconal orbital cystic schwannoma in Brazilian literature. The tumor grew slowly and progressively and was associated with minimal eccentric proptosis and diplopia. The radiologic study (orbital computed tomography) revealed a rounded, encapsulated, and extraconal cystic mass in the superior medial region of the right orbit in the supraorbital and supratrochlear nerve topography. An anterior orbitotomy with full excision of the tumor was performed, and the histopathology examination revealed that the tumor was a schwannoma. After the surgery, the patient experienced total remission of his symptoms.

title: Iris metastases from systemic cancer: a report of three cases

description: ABSTRACT Ocular metastasis is relatively uncommon, with a reported incidence of approximately 8%, according to the results of autopsy evaluation. The majority of ocular metastases are located within the choroid, while metastatic tumors affecting the iris are rare. Metastatic tumors may manifest as stromal nodules or ill-defined iris thickening, or they may present with nonspecific features such as pain, iridocyclitis, and hyphema. Here, we describe three patients with iris metastasis and discuss the diagnostic challenges and unusual findings associated with these cases.
