ESASO classification relevance in the diagnosis and evolution in diabetic macular edema patients after dexamethasone implant treatment.

Purpose: To assess the clinical relevance of The European School for Advanced Studies in Ophthalmology (ESASO) classification in patients with diabetic macular edema (DME) after their first dexamethasone implant (DEXI) treatment.

Methods: Retrospective real-world study conducted on consecutive DME patients who underwent DEXI treatment and were controlled at month-2. Subjects were initially classified according to the ESASO classification stages.

Influence of prior treatment protocol on intravitreal dexamethasone implant behavior in patients with diabetic macular edema in real-world practice.

Background And Objective: Intravitreal dexamethasone implant (DEXI) has been placed as an effective option to treat diabetic macular edema (DME). However, there is no consensus on the best time to introduce it. We conducted a study to evaluate anatomical and functional behavior after the first DEXI according to previous treatment.

Comparison between standard and wide-field autofluorescence in detection of retinal displacement after rhegmatogenous retinal detachment surgery.

Purpose: To analyse the differences between 30° blue autofluorescence (BAF30), 55° blue autofluorescence (BAF55) and 200° green Ultra-Wide Field autofluorescence (UWF200) imaging to detect retinal displacement (RD) after vitrectomy surgery for rhegmatogenous retinal detachment (RRD).

Methods: This cross-sectional study considers forty-nine consecutive patients who underwent RRD surgery in the time period 4-8 months previous to image acquisition. The exclusion criteria contemplate previous retinal pathology, under 18-year-olds and non-assessable images in any of the 3 devices.

Acute dacryoadenitis in a patient with SARS-CoV-2 infection.

We describe a retrospective case report of dacryoadenitis associated with orbital inflammatory disease in a patient with confirmed SARS-CoV-2 infection.A 22-year-old previously fit and healthy male presented with 4-day history of right ocular redness, eyelid swelling and blurred vision associated with discomfort and pain in the lacrimal gland area. He was found to have right acute dacryoadenitis based on clinical examination and orbital imaging.

WDR36 and P53 gene variants and susceptibility to primary open-angle glaucoma: analysis of gene-gene interactions.

Purpose: To investigate the role of WDR36 and P53 sequence variations in POAG susceptibility.

Methods: The authors performed a case-control genetic association study in 268 unrelated Spanish patients (POAG1) and 380 control subjects matched for sex, age, and ethnicity. WDR36 sequence variations were screened by either direct DNA sequencing or denaturing high-performance liquid chromatography.

CYP1B1 mutations in Spanish patients with primary congenital glaucoma: phenotypic and functional variability.

Purpose: To analyze the contributions of cytochrome P4501B1 (CYP1B1) mutations to primary congenital glaucoma (PCG) in Spanish patients.

Methods: We analyzed, by polymerase chain reaction (PCR) DNA sequencing, the presence of promoter (-1 to -867) and exon CYP1B1 mutations in 38 unrelated Spanish probands affected by PCG. Functional analysis of nine identified mutations was performed measuring ethoxyresorufin O-deethylation activity and CYP1B1 stability in transiently transfected human embryonic kidney 293T (HEK-293-T) cells.

R124C and R555W TGFBI mutations in Spanish families with autosomal-dominant corneal dystrophies.

Purpose: Mutations in the transforming growth factor beta I (TGFBI) gene cause several types of autosomal-dominant corneal dystrophies. We investigated the role of this gene in two Spanish families affected by lattice type I or granular type I corneal dystrophies.

Methods: We recruited 13 subjects from two unrelated families diagnosed with autosomal dominant lattice type I or granular type I corneal dystrophies.

Heterozygous CYP1B1 gene mutations in Spanish patients with primary open-angle glaucoma.

Purpose: To investigate CYP1B1 gene mutations in Spanish patients with ocular hypertension (OHT) or primary open angle glaucoma (POAG).

Methods: The two coding exons of CYP1B1 were screened for sequence alterations by direct PCR DNA sequencing in 37 and 82 unrelated Spanish subjects diagnosed with OHT and POAG, respectively. As a control we used a group of 93 subjects from whom OHT or glaucoma were ruled out.
