Background: Anterior uveitis is a common manifestation in individuals with rheumatic conditions such as spondylarthritis, Behçet's syndrome, juvenile idiopathic arthritis, and sarcoidosis. Clinical differentiation between granulomatous and non-granulomatous corneal endothelial exudates is crucial to subsequent diagnosis and treatment. Anterior segment optical coherence tomography (AS-OCT) can ensure an accurate differential diagnosis and appropriate follow-up after local and systemic therapy.

The aim of this review was to investigate the novel application of bioscaffolds in stem cell and regenerative treatments for the treatment of corneal disorders. The current literature reports that organic and artificial substances create bioscaffolds that imitate the inherent structure of the cornea, facilitating the attachment, growth, and specialization of stem cells.

Methods: This observational and cross-sectional study included patients affected by idiopathic intracranial hypertension with papilledema (IIHWP) and patients with idiopathic intracranial hypertension without papilledema (IIHWOP). All participants underwent an OCT examination of the macula and optic nerve head.
Article Synopsis
- A 60-year-old male patient with Hereditary Angioedema (HAE) experienced bilateral vision loss during an attack, despite treatment with intravenous C1-esterase inhibitor initially resolving swelling but not the vision issue.
- Imaging revealed bilateral edema of the optic nerve sheath, and treatment with steroids was ineffective.
- After starting a prophylactic regimen of subcutaneous C1-esterase inhibitor, the patient's visual acuity fully restored within two months, demonstrating that such patients can benefit from consistent prophylactic treatment.
The corneal epithelium, representing the outermost layer of the cornea, acts as a barrier to protect the eye against external insults such as ultraviolet B (UV-B) radiations. The inflammatory response induced by these adverse events can alter the corneal structure, leading to visual impairment. In a previous study, we demonstrated the positive effects of NAP, the active fragment of activity-dependent protein (ADNP), against oxidative stress induced by UV-B radiations.

It is subjected daily to different insults, and ultraviolet B (UV-B) irradiation represents one of the main causes of injury. In our previous study, we demonstrated the beneficial effects of pituitary adenylate cyclase-activating polypeptide (PACAP) against UV-B radiation damage in the human corneal endothelium.

Methods: In this cross-sectional multicenter clinical study, eyes with a minimum 12-month follow-up were reexamined. The RPCP VD and RNFL thickness in the rhegmatogenous retinal detachment subfields of the affected eye (study group) were compared with the corresponding areas of the healthy fellow eyes (control group).
Background: In systemic sclerosis (SSc) patients, dry eye syndrome (DES) is the most frequent ocular feature. The aim of this study was to investigate ocular DES-related SSc patients and to establish any correlation with the severity of the disease.
Methods: Retrospectively, data from 60 patients with SSc underwent ophthalmic examination, where non-invasive film tear break-up time (NIF-TBUT), tear film lipid layer thickness (LLT), anesthetic-free Schirmer test I, tear osmolarity measurement (TearLab System), and modified Rodnan skin score (mRSS) data were collected.
Purpose: To analyse the postoperative foveal avascular zone (FAZ) area, superficial vessel density (SVD) and deep vessel density (DVD) and their correlation with functional (best-corrected visual acuity, BCVA) and anatomical outcomes (foveal macular thickness, FMT) after surgery for rhegmatogenous retinal detachment (RRD) repair.
Method: Patients with RRD eyes, successfully treated with a single pars plana vitrectomy (PPV) with gas tamponade and a minimum 12 months follow-up, were re-examined. Foveal avascular zone (FAZ) area, SVD, DVD and FMT were evaluated by using optical coherence tomography angiography (OCTA) and compared to fellow eye.
Purpose: To evaluate the intraocular pressure (IOP) and central corneal thickness (CCT) in premature and full-term newborns.
Methods: IOP and CCT were determined in 33 premature (mean [± SD] gestational age 31 ± 3 weeks, mean birth weight 1474 ± 354 g) and in 33 full-term white newborns (mean gestational age 39 ± 1 weeks, mean birth weight 2763 ± 574 g). The mean age after birth at measurement was respectively 3 ± 1 weeks and 1 ± 1 weeks.
Ocular hypotensive effect of oral palmitoyl-ethanolamide: a clinical trial.
Invest Ophthalmol Vis Sci
August 2011
Purpose: To investigate the effect of oral palmitoyl-ethanolamide (PEA) on intraocular pressure (IOP) in primary open angle glaucoma (POAG) and ocular hypertension (OH).
Methods: In a prospective, randomized, double-blind, crossover clinical trial, 42 patients with POAG or OH who were treated with timolol 0.5% and whose IOP was between 19 and 24 mm Hg received oral PEA (300-mg tablets twice a day) or placebo (PEA vehicle tablets twice a day) for 2 months (period 1), and, after a 2-month washout, received the other treatment for 1 month (period 2).
Purpose: Since, during the menstrual cycle, changes in neuronal activity and in auditory, olfactory, and taste thresholds were found, visual evoked potentials were investigated.
Materials & Methods: In 50 healthy women the latency and the amplitude of P100 wave of pattern reversal visual evoked potentials were measured during the different menstrual phases (follicular, periovular, and luteal), as determined by sonography and serum progesterone level.
Results: Compared with the follicular phase, during the luteal phase significant reduction in latency (101.
