PURPOSE: To highlight tomographic structural changes of retinal layers after internal limiting membrane (ILM) peeling in macular hole surgery. METHODS: Nonrandomized prospective, interventional study in 38 eyes (34 patients) subjected to pars plana vitrectomy and ILM peeling for idiopathic macular hole. Retinal layers were assessed in nasal and temporal regions before and 6 months after surgery using spectral domain optical coherence tomography. RESULTS: Total retinal thickness increased in the nasal region and decreased in the temporal region...

PURPOSE: The hypothesis that oral supplementation of the epilutein/lutein combination could augment the macular pigment optical density (MPOD) in patients with age-related macular degeneration (AMD) was tested. METHODS: In a prospective randomized interventional study, 40 consecutive patients with early-stage AMD were recruited. After a 2-week run-in period, patients were randomly treated with a daily oral administration of 8 mg epilutein and 2 mg lutein (group 1) or 10 mg lutein (group 2) for 2 months...

AIMS: To evaluate and compare peripapillary choroidal thickness (PPCT) in a wide area around the optic disk and various choroidal established zones in healthy controls and primary open-angle glaucoma (POAG) patients using a new swept-source (SS) optical coherence tomography (OCT) device. METHODS: A total of 246 eyes were finally included in this observational, prospective, cross-sectional study: 111 healthy controls and 135 POAG patients. The healthy subjects were divided into 2 populations: the teaching population (25 used to establish choroidal zones) and the validating population (86 used for comparing choroidal thickness with POAG patients)...

BACKGROUND: This study aimed to explore the inhibitory effect of biodegradable scleral plugs containing curcumin on rabbits with proliferative vitreoretinopathy (PVR). MATERIALS AND METHODS: The biodegradable scleral plugs containing curcumin were prepared by dissolving PLGA [poly(lactide-co-glycolide)] and curcumin. In total, 30 rabbits were divided into 2 groups: the model group received a vitreous injection of self-blood, and the treatment group received a vitreous injection of self-blood plus biodegradable scleral implants containing 1...

BACKGROUNDS: There is still a lack of consensus about how to assess the risk of peripheral arterial disease (PAD) and cardiovascular disease (CVD) in patients with diabetic retinopathy (DR). AIMS: We investigated the risk factors for DR and their association with PAD and CVD in patients with type 2 diabetes (T2D). METHODS: A total of 1,421 patients diagnosed with T2D participated in this study. DR stages were classified as non-DR, nonproliferative DR (NPDR), or proliferative DR (PDR)...

PURPOSE: To investigate the influence of hormone therapy with tamoxifen or estrogens on morphological changes in macular telangiectasia (MacTel) type 2 patients as revealed clinically in multiple imaging modalities. METHODS: Patients with a history of tamoxifen or estrogen use were selected from the cohort of the MacTel Study. A race-, age- and best-corrected visual acuity-matched group of MacTel participants not under hormone therapy served as the comparison group...

AIM: To compare ganglion cell (GCL) and inner plexiform layer (IPL) thickness in patients at different stages of primary open-angle glaucoma (POAG), determine their sensitivity and specificity values, and correlate thickness values with mean deviations (MD). METHODS: This prospective, cross- sectional study was conducted in a group of patients with confirmed POAG who were compared to an age- and gender-matched control group. Glaucomatous damage was classified according to the Hodapp-Parrish-Anderson scale: glaucoma stage 1 (early), glaucoma stage 2 (moderate), and glaucoma stage 3 (severe)...

PURPOSE: The purpose of this study was to investigate the potential association between rhegmatogenous retinal detachment (RRD) and BAX and BCL2 polymorphisms. METHODS: This is a case control study of 99 patients with RRD and 120 healthy control subjects of Greek origin, surveyed for BAX and BCL2 polymorphisms (rs2279115 and rs4645878) and a potential correlation to RRD. RESULTS: The rs4645878 AA genotype was found to be significantly associated with RRD (p = 0...

Glaucoma is one of the leading causes of irreversible blindness worldwide. However, there are no biomarkers that accurately help clinicians perform an early diagnosis or detect patients with a high risk of progression. Metabolomics is the study of all metabolites in an organism, and it has the potential to provide a biomarker. This review summarizes the findings of metabolomics in glaucoma patients and explains why this field is promising for new research. We identified published studies that focused on metabolomics and ophthalmology...

Compared to intravitreal injection, subretinal injection has more direct effects on the targeting cells in the subretinal space, which provides a new therapeutic method for vitreoretinal diseases, especially when gene therapy and/or cell therapy is involved. To date, subretinal delivery has been widely applied by scientists and clinicians as a more precise and efficient route of ocular drug delivery for gene therapies and cell therapies including stem cells in many degenerative vitreoretinal diseases, such as retinitis pigmentosa, age-related macular degeneration, and Leber's congenital amaurosis...

PURPOSE: To identify current challenges facing ophthalmic pharmaceutical start-ups in developing new products. METHODS: Surveys were distributed to the chief executive officer (CEO) or president of ophthalmic start-ups. RESULTS: The survey attracted 24 responses from 78 surveys distributed (31%). The CEOs stated that a lack of financial capital (n = 18, 75%), FDA regulations (n = 6, 25%), and failure to meet clinical endpoints (n = 6, 25%) were their greatest development hurdles...

PURPOSE: To investigate the repeatability and reproducibility of mapping the entire corneal thickness using spectral domain optical coherence tomography (SD-OCT). METHODS: Thirty normal eyes, 30 post-laser in situ keratomileusis (LASIK) surgery eyes, and 30 keratoconus eyes were analyzed. A custom-built long scan depth SD-OCT device was used to obtain entire corneal images. Ten-millimeter-diameter corneal thickness maps were generated by an automated segmentation algorithm...

PURPOSE: Our experiment evaluated the biomechanical effects of riboflavin and ultraviolet A illumination, in terms of covalent bonding, permeability, and indentation rupture force, on excised cattle conjunctiva. MATERIALS AND METHODS: Cattle conjunctiva was extracted and divided into the treatment group, which was soaked in riboflavin, followed by ultraviolet light illumination, and the control group. Samples were subsequently analysed on a Fourier transform infrared spectrum test to identify the presence of amide bonds, a permeability test to assess the diffusion of methylene blue across conjunctiva, and an indentation rupture force test...

Qi Wan, Jing Tang, Yu Han, Dan Wang, Hongquan Ye
OBJECTIVE: The purpose of this study was to evaluate the efficacy and safety of 0.1% tacrolimus eye drops in the tarsal form of vernal keratoconjunctivitis (VKC) and to survey the changes of dendritic cells at the palpebral conjunctiva in patients with VKC by in vivo confocal microscopy. METHODS: A total of 17 patients (34 eyes) with the tarsal form of VKC were enrolled in this prospective, nonrandomized case series. They were treated with 0.1% tacrolimus eye drops twice daily after discontinuation of all other topical medications...

PURPOSE: To determine whether intravitreal unconjugated tissue plasminogen activator (tPA) (alteplase) can penetrate the intact neural retina and reach the subretinal space in an experimental model. METHODS: This study was performed in 24 Sprague-Dawley rats aged 12 weeks. Under general anesthesia, the right eye was injected with either 0.75 μg of 3 μL tPA (14 rats; study group) or saline (10 rats, control group) into the vitreous. Animals were euthanized at 3, 24, and 48 h...
