ABSTRACT Objective: To evaluate the tear film and dry eye symptoms before and after phacoemulsification. Methods: Fifty-one patients diagnosed with cataracts participated in this clinical study (55% female; 78% white; 71.2 ± 6.5 years old; without the use of lubricating eye drops) and underwent phacoemulsification at a hospital in Aparecida (SP). Tear film analysis was performed by the tear film break-up test and dry eye symptoms were assessed by the Ocular Surface Disease Index, both before surgery and 30 and […]

ABSTRACT Topography-guided ablation was designed to improve corneal regularity throughout the correction of corneal high order aberrations. The present report described three cases with different indications for topography-guided ablation to correct irregular astigmatism. The patients were monitored in the immediate and late postoperative periods to evaluate long-term corneal stabilization. Surgery indications were based on the patient’s complaint of poor quality of vision associated with previous radial keratotomy, corneal transplant, or keratoconus. In all three cases, the patients reported an improvement […]

ABSTRACT Objective: To study vertex-optical distance variation and estimate its impact on manifest refraction. Methods: Prospective study in a private clinic using the Vision-S™ 700 with five forehead positions. Forehead on the third position showed the closest vertex-optical distance of 12mm. Results: Analysis of 52 eyes from 26 patients revealed mean differences in vertex-optical distance of 12.25mm (right eye) and 11.75mm (left eye). A 2mm change in vertex-optical distance resulted in a 0.05D change for a 5D spherical equivalent and […]

ABSTRACT This case series describes four patients who presented with retinal and optic nerve vascular occlusions after administration of different COVID-19 vaccines. The first patient received the ChAdOx1 nCoV-19 vaccine (AZD1222; Oxford/AstraZeneca) and 42 days later developed central retinal artery occlusion. The second patient developed a painless visual impairment in the left eye and was diagnosed with anterior ischemic optic neuropathy 6 days after receiving the Sinovac-CoronaVac vaccine. The third patient presented with the same condition 22 days after receiving […]

ABSTRACT Objective: To evaluate the epidemiological, clinical, and imaging profile of lesions that mimic choroidal melanoma. Methods: Retrospective study of medical records of suspected choroidal melanoma lesions referred to the Ocular Oncology Service from the Universidade Federal de São Paulo, from 2014 to 2020. Demographic data, clinical history, and exams were evaluated. Results: A total of 104 patients (mean age: 65.57 ± 13.18; 49.04% female) were referred to our service with suspected choroidal melanoma. Of these, 32 (30.77%) were classified […]

ABSTRACT Objective: To determine the prevalence of ocular alterations in patients diagnosed with dengue, admitted to a reference center for infectious and parasitic diseases in Manaus (AM), Brazil. Methods: This was an observational, analytical, and prospective case series study with 33 patients admitted to the hospital with positive clinical pathology tests during a 90-day period of a dengue epidemic in 2011. The investigations included measurement of visual acuity, macular assessment with Amsler grid test, fundus biomicroscopy, retinography and optical coherence […]

ABSTRACT Retinal detachment related to retinopathy of prematurity is a surgical challenge, and vitrectomy can directly release transvitreal traction resulting from fibrous proliferation. The presence of iatrogenic breaks is a poor prognostic factor and has been considered a dismal prognosis. We report a case of premature female baby that underwent a 3-port 23-Gauge pars plana vitrectomy for stage 4A retinopathy of prematurity, with intraoperative progressive rhegmatogenous detachment complication. Lensectomy, extensive membrane dissection and vitreous shaving, followed by a posterior retinotomy, […]

ABSTRACT Ankyloblepharon filiforme adnatum is a rare congenital anomaly, characterized by partial or complete palpebral fusion, with an incidence of 4.4 per 100,000 newborns. Normally, ankyloblepharon filiforme adnatum constitutes a solitary malformation, with sporadic occurrence, however, it can be associated with other malformations. Pediatricians play an essential role in observing clinical changes in newborns and providing guidance on appropriate treatment. The this study aims to report the case of a full-term newborn who had an early diagnosis of ankyloblepharon filiforme […]
