Purpose: To determine the influence of strabismus and its surgical correction on the preoperative and postoperative functional and psychosocial aspects of patients being treated at the CEROF/UFG Strabismus Outpatient Clinic. Methods: This prospective cross-sectional study included 27 patients, aged >7 years that were divided into two groups (<18 years and >18 years). The AS 20 questionnaire is composed of two domains (psychosocial and functional). Each domain includes 10 questions, which should be answered using a 5-point Likert scale. The questionnaire was administered preoperatively and 3 months postoperatively. In patients aged <18 years, the questionnaire was concurrently administered to their parents and/or guardians. Results: Preoperatively, the average psychosocial and functional scores were 55 (p=0.01) and 57.5 (p=0.025), respectively, in adults, 70 (p=0.03) and 78.7 (p=0.16), respectively, in children and adolescents, and 46.2 (p=0.002) and 57.5 (p=0.003), respectively, in the parents and/or guardians. Postoperatively, the average psychosocial and functional scores were 80 (p=0.01) and 82.5 (p=0.025), respectively, in adults, 81.2 (p=0.03) and 85 (p=0.16), respectively, in children and adolescents, and 83.7 (p=0.002) and 86.2 (p=0.003), respectively, in parents and/or guardians. Conclusion: The postoperative scores in the psychosocial (p=0.001), functional (p=0.001) and general (p<0.001) domains had increased in all the patients, demonstrating an improvement in the quality of life following strabismus correction surgery [ABSTRACT FROM AUTHOR]

Background and Objectives: To compare the needle path during retrobulbar ophthalmic block with that during peribulbar ophthalmic block, its relation with anesthetic spread, and the quality of the anesthesia.Methods: This is a prospective comparative study in selected candidates of ophthalmic blocks for phacoemulsification. The procedure used a 22-gauge 1 needle in a single lateral inferior transcutaneous puncture with 5 mL of anesthetic solution with radiological contrast. Patients were randomly divided into 2 groups: GI, retrobulbar block; GII, peribulbar block. Computed tomography scans of the orbit were performed at the time of the blockade and 10 minutes after anesthetic injection. The quality of anesthesia was assessed by measurement of ocular motility at 3, 5, and 10 minutes after the block.Results: Twenty eyes per group were included. The needle path was intraconal in 10 cases in GI and in no patient in GII, transfixed the muscle cone in 5 cases in GI and in 4 in GII, and was extraconal in 2 cases in GI and in 13 in GII. The anesthetic dispersion was directly related to the needle path. In all extraconal cases, the block was unsatisfactory. It was satisfactory when the path of the needle was intraconal or the cone was transfixed (P = 1.0). The quality of anesthesia was higher in the retrobulbar block (P < 0.01).Conclusions: The path of the needle contributed to the orbital anesthetic solution dispersion and the quality of anesthesia. The retrobulbar block technique provided better-quality anesthesia compared with the peribulbar one. [ABSTRACT FROM AUTHOR]

Objective: To identify the levels of visual impairment and prevalence of eye diseases and refractive errors in children seen at a referral center for ophthalmology in the Central-West region compare findings with published data for other regions of Brazil. Methods: Crosssectional, descriptive and retrospective analysis of medical records of children enrolled in the Center of Reference in Ophthalmology Universidade Federal de Goiás, in the period between april 2009 and march 2010. Results: A total of 2408 patient charts, and 2128 (88.4%) of elective care and 280 (11.6%) of care in the emergency department CEROF. Predominated in the age group 6-10 years (44.2%), followed by 11-14 years (29.6%). The examination was normal in 12.9% (n=274) of elective care and 6.8 (n=19) of emergency visits. The disease most commonly found in children were infectious conjunctivitis (248 cases, 26.4%) and allergic (204 cases, 21.7%), blepharitis (69 cases, 7.3%), chalazion (34 cases, 3.6 %), strabismus (133 cases, 12.06%), diseases of retina and vitreous (24 cases, 2.6%), cataract and lens changes (20 cases, 2.1%). Ametropia frequently told by eye, were hyperopia (46.9%) and astigmatism (42.2%) and systemic diseases were more informed prematurity (30 cases) and diabetes mellitus (26 cases). Conclusion: This study identified the main causes of eye diseases in children seen in a university referral center. The group of diseases more prevalent was the disease of the cornea and conjunctiva (allergic conjunctivitis, dry eye and keratitis). Diseases were the second eyelid (blepharitis, chalazion, and lacrimal obstructions). The refractive errors were the most common hyperopia and astigmatism. The findings in the study population are shown similar to those observed in the national literature. [ABSTRACT FROM AUTHOR]

Background: Conventional vitrectomy technique for macular hole surgery has a good outcome in small and medium macular holes, but for very large macular holes (minimum linear diameter higher than 700 μm) other techniques were developed aiming to achieve greater rates of closure and visual acuity gain. The purpose of this article is to report the anatomical and functional outcomes of four very large macular hole (MH) cases which have undergone vitrectomy with the pedicle internal limiting membrane (ILM) flap technique. Methods: This is a retrospective series of four patients with large MH who were treated with vitrectomy and the pedicle ILM flap technique. Comprehensive ophthalmologic evaluation was performed before surgery and included ETDRS best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography (SD-OCT) for MH measures: height, minimum linear diameter (MLD) and external base diameter. The particular detail of this technique is related to ILM flap creation. During the peeling, the ILM was not removed completely from the retina but was left attached to the edges of the macular hole and subsequently trimmed with the vitrectomy probe using the scissors mode. Results: Four patients with very large MH underwent PPV and the pedicle ILM flap technique was used to pursue macular closure. Median preoperative BCVA was 20/400 (range: 20/320 to 20/400) and median postoperative BCVA was 20/200 (range: 20/320 to 20/200). Of the 4 cases reported, 3 obtained anatomical closure (75%), and also presented BCVA improvement after surgery, considering the last follow-up visit of each case. No additional procedures were performed in either case. One patient demonstrated no anatomic and functional improvement. Conclusion: The present study describes the first Brazilian case series of very large MH treated by the inverted pedicle ILM flap technique. This technique was associated with anatomic and visual improvement in most cases, and represents an alternative therapeutic approach for large macular holes.

In this study, we aimed to analyze the effect of 5-fluorouracil, triamcinolone, and bevacizumab on scar modulation in an experimental rat model of surgical lesions. Rats (Rattus norvegicus albinus) were divided into four groups: bevacizumab, 5-fluorouracil + triamcinolone, bevacizumab + 5-fluorouracil + triamcinolone, and control (received no medication) groups. A linear, dorsal incision was created and sutured for the first intention wound healing, mimicking the surgical incision of upper blepharoplasty. Treatments were initiated on day 7, and the rats were euthanized on day 14. Only in the 5-fluorouracil + triamcinolone group was there a difference in the number of infiltrated monocytes. There was 56%, 86%, and 85% decrease in the number of neovessels in the bevacizumab, 5-fluorouracil + triamcinolone, and bevacizumab + 5-fluorouracil + triamcinolone groups, respectively, compared with the control. Picrosirius red staining showed higher collagen density and more organized collagen in the treatment groups than in the control group. Scar modulation was observed in all groups, but the 5-fluorouracil + triamcinolone group presented the best results. To our knowledge, this is the first study to evaluate the influence of three medications in combination on healing. When used together, these medications can prevent the development of unsightly scars, and are therefore promising alternatives to corticosteroids., (©The Author(s) 2023. Open Access.

Purpose: To establish the prevalence and risk factors for intravitreal dexamethasone implant migration into the anterior chamber in eyes with macular edema., Methods: This was a multicenter, retrospective, observational chart review of data that included patients with macular edema who had been treated with at least one intravitreal dexamethasone injection. Patients with incomplete chart information during the follow-up period were excluded., Results: The prevalence of implant migration in 468 patients, considering the number of injections, was 1.6%, with significant associations between implant migration and cataract surgery (P = 0.043) and intraocular lens status (P = 0.005) and a trend toward statistical significance (P = 0.057) with vitrectomy. A higher rate of implant migration into the anterior chamber was observed in vitrectomized eyes (4.8%) when compared with patients who did not undergo a vitrectomy (1.6%). The implants that migrated were removed with forceps with/without viscoelastic expression or with 20-gauge cannulas connected to the vitreous cutter machine., Conclusion: The risk of implant migration into the anterior chamber was 1.6%. Risk factors were a history of cataract surgery or vitrectomy and aphakia. When anterior migration occurs, rapid removal is advised, especially if corneal edema is present.

Aim: To evaluate the clinical and tomographic outcomes after implantation of a new intrastromal corneal ring segment (ICRS) with 140-degrees of arc in eyes with corneal ectasia., Methods: We evaluated patients with corneal ectasia implanted with Ferrara 140° ICRS from April 2010 to February 2015. Outcome measures included preoperative and postoperative corrected distance visual acuity (CDVA), keratometry simulated (K) reading, tomographic astigmatism and asphericity. All patients were evaluated using the Pentacam Scheimpflug system., Results: The study evaluated 58 eyes. The mean follow-up was 16.81±10.8mo. The CDVA (logMAR) improved from 0.5±0.20 (20/60) to 0.3±0.21 (20/40) ( P <0.01). The average K reduced from 49.87±7.01 to 47.34±4.90 D ( P <0.01). The asphericity changed from -0.60±0.86 to -0.23±0.67 D ( P <0.01). The mean preoperative tomographic astigmatism decreased from -8.0±3.45 to -4.53±2.52 D ( P <0.01)., Conclusion: The new ICRS model with 140-degrees of arc effectively improve the visual acuity and reduce the high astigmatism usually found in patients with corneal ectasia.
