Purpose: To determine the safety and feasibility of human autologous adipose tissue-derived adult mesenchymal stem cells (ASCs) for ocular surface regeneration in patients with bilateral limbal stem-cell deficiency (LSCD).

Methods: A phase IIa clinical trial was designed (https://Clinicaltrials.gov, NCT01808378) with 8 patients, 3 of whom had aniridia, 2 meibomian glands diseases, 2 multiple surgeries and 1 chronic chemical injury.

Article Synopsis
  • * A case study is presented involving a male jeweler with corneal argyrosis, showing small whitish-gray deposits observed through biomicroscopy and confocal microscopy.
  • * The patient experienced significant contrast sensitivity impairment in low light, which suggests that testing could identify retinal issues before structural changes are observable.

Ocular diseases have a strong impact on individuals, the effects of which extend from milder visual impairment to blindness. Due to this and to their prevalence, these conditions constitute important health, social and economic challenges. Thus, improvements in their early detection and diagnosis will help dampen the impact of these conditions, both on patients and on healthcare systems alike.

Posterior polymorphous corneal dystrophy (PPCD), a rare, bilateral, autosomal-dominant, inherited corneal dystrophy, affects the Descemet membrane and corneal endothelium. We describe an unusual presentation of PPCD associated with a previously unknown genetic alteration in the ZEB1 gene. The proband is a 64-year-old woman diagnosed with keratoconus referred for a corneal endothelium study who presented endothelial lesions in both eyes suggestive of PPCD, corectopia and iridocorneal endothelial synechiae in the right eye and intrastromal segments in the left eye.

Purpose: The aim of this study was to report the results of screening peroxiredoxin 3 (PRDX3) and PDZ domain-containing protein 8 (PDZD8) in a previously unreported pedigree with punctiform and polychromatic pre-Descemet corneal dystrophy (PPPCD) to confirm that the PRDX3 mutation c.568G>C is the genetic basis of PPPCD.

Methods: Ophthalmologic examination of the proband and her affected father was performed with slit lamp biomicroscopy.

Article Synopsis
  • - The study investigates three unreported families with punctiform and polychromatic pre-Descemet corneal dystrophy (PPPCD), examining clinical features and genetic factors associated with the condition.
  • - Researchers performed extensive ocular assessments, whole exome sequencing, and Sanger sequencing, identifying a significant increase in corneal stiffness and two specific genetic variants linked to PPPCD across the families.
  • - Findings suggest that PPPCD affects corneal biomechanics and is linked to a novel variant in the PRDX3 gene; further screening of additional families is needed to explore the genetic complexity of the disorder.

Article Synopsis
  • A 68-year-old woman with cancer-associated retinopathy (CAR) experienced a month-long decline in vision, which led to the discovery of retinal atrophy and the diagnosis of small cell lung carcinoma related to anti-recoverin antibodies.
  • The treatment approach included corticosteroids and intravenous immunoglobulin (IGIV), which helped stabilize her visual loss.
  • A literature review revealed only 12 similar CAR cases treated with IGIV, suggesting that early IGIV use may improve or stabilize visual symptoms while minimizing adverse effects when combined with chemotherapy.

Purpose: To describe and analyze the biomicroscopic features and in vivo confocal microscopy of the crystalline form of pre-Descemet corneal dystrophy (PDCD).

Methods: We examined two non-related families using biomicroscopy, in vivo confocal microscopy, and a genetic study using a gene panel test, looking for mutations in the PIKFYVE gene.

Results: A slit-lamp examination of the first family revealed polychromatic crystalline punctiform opacities distributed all over the stroma in 8 of 11 family members in three generations with an autosomal dominant inheritance.

Introduction: To study antibiotic susceptibility in bacterial keratitis (BK), its profile over 10 years and its influence on ophthalmological practice.

Methods: Retrospective review of BK with positive corneal scraping over a 10-year period. Risk factors for keratitis, visual acuity (VA), empirical topical treatment, corneal infection characteristics and outcomes were analyzed for BK due to Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Pseudomonas aeruginosa and Propionibacterium acnes.

Purpose: A case of ocular pythiosis successfully treated with surgery and intraocular and oral minocycline is reported.

Summary: A 30-year-old man who wore corrective contact lenses traveled to Brazil and Colombia where he swam in salt and fresh waters while wearing contact lenses. He sought treatment at an emergency department after 2 weeks of suffering with a painful corneal ulcer, redness, and loss of vision in his right eye that had been treated at other centers with ophthalmic moxifloxacin for 10 days and with fortified topical antibiotics (amikacin and vancomycin) for 2 days.

This article examines the clinical presentation of ocular metastasis from an infiltrating lobular breast carcinoma. We examined a conjunctival biopsy from a 69-year-old woman who developed unilateral conjunctival inflammation together with a neurotrophic corneal ulcer and proptosis. Infiltrating lobular breast carcinoma (ILBC) was diagnosed using routine histology and immunohistochemistry.

Conjunctival impression cytology samples from patients with meibomian gland dysfunction (MGD), dry eye (DE), and healthy subjects (CT) were collected for determination of the degree of squamous metaplasia (SM) by PAS-hematoxylin staining and for comparative proteomic analyses by 2D-DIGE. The protein spots with discriminant expression were identified by MALDI-TOF/TOF mass spectrometry. Three independent statistical studies were conducted: i).

Background: Methylphenidate hydrochloride is used as first-line treatment for attention deficit hyperactivity disorder (ADHD). However, there is concern that this treatment may be associated with increased risk of angle closure glaucoma and disturbance of ocular refraction. The aim of this study was to investigate the effects of methylphenidate treatment on refraction, intraocular pressure, and the anterior chamber in children with ADHD.

We report a case of an immunocompetent woman with atypical marginal keratitis. She presented with recurrent episodes of multiples microabscess distributed in a triangular pattern associated with stromal oedema and anterior chamber uveitis, affecting both eyes, but not simultaneously. The episodes responded to steroid drops, corneal inflammation was coincidental with a worsening of her blepharitis in the affected eye and S.

Objectives: To report a case of atypical herpes keratitis and bilateral conjunctivitis associated with human herpesvirus 6 (HHV-6).

Methods: An immunocompetent 34-year-old man was referred for herpetic epithelial keratitis in his left eye, which was non-responsive to topical acyclovir. Biomicroscopy revealed a central dendritic ulcer with a white stromal infiltrate beneath the ulcer.

Purpose: To evaluate the sensitivity and specificity of a PCR-strip system based on reverse dot blot for detection of MUC5AC mRNA in corneal epithelium samples from patients with limbal stem cell deficiency (LSCD), and to determine the correlation with clinical diagnosis.

Methods: We obtained 87 corneal impression cytology (IC) samples from 55 subjects (37 patients clinically diagnosed with LSCD and 18 control subjects). Total RNA was extracted from each IC sample and retrotranscribed to cDNA.
