Purpose: To describe the demographic characteristics and clinical course of Fuchs endothelial corneal dystrophy (FECD) in a Mexican-mestizo population.
Methods: A retrospective observational and longitudinal study was performed in consecutive patients with the clinical diagnosis of Fuchs endothelial corneal dystrophy seen at our institution. Initial and last follow-up best-corrected visual acuity, slit-lamp findings, and specular microscopy endothelial morphometric parameters were analyzed.
Results: One hundred and two eyes belonging to 51 patients were included in the analysis. Median age at the time of diagnosis was 69 years (range, 25-87 years) with a female-to-male ratio of 3.3:1. Visual loss (40%) followed by glare (13.3%) and fluctuating matutine vision loss (13.3%) was the most common complaints at presentation. Regarding FECD staging, 65 (63.7%) were classified as stage-I FECD, 21 (20.6%) stage-II, and 15 (14.7%) as stage-III. A high percentage of eyes (44.1%) presented visual impairment ( ≤ 20/50) at presentation, and the presence of isolated corneal guttata was the most common stage of presentation (64%) at slit-lamp examination. While fifty-nine (57.8%) eyes did not require any medical or surgical management, 17 (16.7%) eyes were managed with hypertonic saline eyedrops alone or in combination with bandage contact lens, and 18 (17.6%) required corneal transplantation. Penetrating keratoplasty alone (8 eyes, 44.4%), or in combination with cataract extraction and intraocular lens implantation (3 eyes, 16.7%), was the most frequent surgical technique performed.
Conclusion: Demographical characteristics of Fuchs dystrophy regarding age at presentation, gender distribution, and clinical stage at the time of diagnosis did not differ significantly from other international reports. Almost 20% of these patients will require keratoplasty during the disease, emphasizing the need for safer and more reproducible keratoplasty techniques.

Background: Nineteen-year follow-up after initial examination on patients with Axenfeld-Rieger anomaly or syndrome (ARAS) and coexisting Fuchs' endothelial dystrophy (FED). All individuals had previously been tested positive for the PITX2 (g.20 913 G>T) mutation.

Purpose: To assess the impact of MitoQ, a mitochondria-targeted antioxidant, on viability of human corneal endothelial cell (hCEnC) lines expressing mutations associated with congenital hereditary endothelial dystrophy (CHED) and Fuchs endothelial corneal dystrophy type 4 (FECD4).
Methods: wildtype () and mutant () hCEnC lines were created to express either variant 2 (V2) or variant 3 (V3) by stable transduction of hCEnC-21T with lentiviruses containing either or one of the following mutations: V2 (V3) mutants c.374 G>A (c.
Purpose: To investigate the effectiveness of mitochondrial-targeted antioxidant mitoquinone (MitoQ) and nontargeted antioxidant idebenone (Idb) in alleviating mitochondrial dysfunction in corneal endothelial cells (CEnCs).
Methods: In vitro experiments were conducted using immortalized normal human corneal endothelial cells (HCEnC-21T; SVN1-67F) and Fuchs endothelial corneal dystrophy (FECD) cells (SVF5-54F; SVF3-76M). Cells were pretreated with MitoQ or Idb and then exposed to menadione (MN) with simultaneous antioxidant treatment.

Purpose: Describe aims, methods, characteristics of donors, donor corneas and recipients, and potential impact of the Diabetes Endothelial Keratoplasty Study (DEKS).
Methods: The DEKS is a randomized, clinical trial to assess graft success and endothelial cell density (ECD) 1 year after Descemet membrane endothelial keratoplasty (DMEK) using corneas from donors with versus without diabetes in a 1:2 minimization assignment. Diabetes severity in the donor is assessed by medical history, postmortem HbA1c, and donor skin advanced glycation end-products and oxidation markers.
