Vitamin D Levels in Patients with Noninfectious Uveitis: A Systematic Review and Meta-Analysis.

Purpose: Vitamin D deficiency has been associated with higher rates of autoimmune disease, including noninfectious uveitis. This PRISMA-compliant review and meta-analysis aimed to analyze the correlation between noninfectious uveitis and vitamin D levels.

Methods: We searched PubMed, Embase, Cochrane, and Web of Science databases for studies, published in English, assessing vitamin D levels in patients diagnosed with noninfectious uveitis.

Agreement between corneal diameter measurements obtained with an optical biometer and a Placido-based topographer.

Purpose: The purpose of this study was to compare the white-to-white distance measurements of two devices (IOL Master 500 and Atlas corneal topographer) commonly used in clinical practice to determine if they were interchangeable. Providing information on instrument interchangeability could eliminate several unnecessary tests and consequently reduce the economic burden for the patient and society.

Methods: In this prospective, comparative case series, the white-to-white distance was measured by independent examiners using the Atlas topographer (Carl Zeiss Meditec) and the IOL Master 500 (Carl Zeiss Meditec).

Morphologic and molecular study on the lens anterior capsule in systemic sclerosis.

This study aimed to analyze the anterior lens capsule specimens from both eyes of a patient with systemic sclerosis and compare them to the eyes of a control patient. No significant differences between systemic sclerosis and control eyes were observed in the results from the hematoxylin-eosin and picrosirius staining. In the samples obtained from both systemic sclerosis and control eyes, there were expressions of caspase, a molecule expressed in cell death by apoptosis.

All patients instilled a tear substitute into the eye with the worst eyesight using the technique normally used at home.

Ophthalmic manifestations in patients with inflammatory bowel disease: A review.

Clinical manifestations of inflammatory bowel disease (IBD) are not locally restricted to the gastrointestinal tract, and a significant portion of patients have involvement of other organs and systems. The visual system is one of the most frequently affected, mainly by inflammatory disorders such as episcleritis, uveitis and scleritis. A critical review of available literature concerning ocular involvement in IBD, as it appears in PubMed, was performed.

Is there an association between glaucoma and capillaroscopy in patients with systemic sclerosis?

Purpose: To evaluate the relationship between glaucoma diagnosis and the nailfold capillaroscopy pattern in patients with systemic sclerosis.

Methods: An observational study in a cohort of patients with SSc was conducted. Patients with at least one nailfold videocapillaroscopy and one ophthalmology examination at the same year were included.

Refractive and Quality of Vision Outcomes with Toric IOL Implantation in Low Astigmatism.

To evaluate the refractive and the quality of vision outcomes of toric IOL implantation in patients with low astigmatism. Prospective study of single-arm. Patients with corneal astigmatism range from 0,75 D to 1,5 D and cataract that underwent cataract surgery with toric IOL.

Accelerated corneal collagen crosslinking: Technique, efficacy, safety, and applications.

Unlabelled: Corneal collagen crosslinking (CXL) is an approach used to increase the biomechanical stability of the stromal tissue. Over the past 10 years, it has been used to halt the progression of ectatic diseases. According to the photochemical law of reciprocity, the same photochemical effect is achieved with reduced illumination time and correspondingly increased irradiation intensity.

Comparison of eyedrop instillation technique with and without a delivery device in inexperienced patients.

Purpose: To compare the instillation of eyedrops with and without Xal-Ease® delivery device in inexperienced patients based on patient observation and answers to a questionnaire.

Methods: This prospective study included consecutive patients considered inexperienced in instilling eyedrops. After a short explanation about the methods, drop instillation technique was evaluated with and without the device.

Predictability and Vector Analysis of Laser In Situ Keratomileusis for Residual Errors in Eyes Implanted With Different Multifocal Intraocular Lenses.

Purpose: To investigate potential differences in predictability, efficacy, and safety of corneal excimer laser to correct residual myopia, hyperopia, and astigmatism in eyes previously implanted with multifocal intraocular lenses using distinct optical surfaces and platforms for multifocality.

Role of optical coherence tomography on corneal surface laser ablation.

This paper focuses on reviewing the roles of optical coherence tomography (OCT) on corneal surface laser ablation procedures. OCT is an optical imaging modality that uses low-coherence interferometry to provide noninvasive cross-sectional imaging of tissue microstructure in vivo. There are two types of OCTs, each with transverse and axial spatial resolutions of a few micrometers: the time-domain and the fourier-domain OCTs.
