PurposeTo determine whether the inverted internal limiting membrane (ILM) flap technique contributes to high reattachment and closure rates in patients with macular hole-associated retinal detachment (MHRD).Patients and methodsIn all, 15 eyes of 15 patients with MHRD undergoing 25-gauge pars plana vitrectomy with the inverted ILM flap technique or ILM peeling. The patients were divided into the inverted ILM flap technique group (6 eyes) and ILM peeling group (9 eyes). The logarithm of minimal angle of resolution best-corrected visual acuity (BCVA) and retinal attachment and macular hole closure rates were compared between the two groups before and after surgery...

PURPOSE: To determine the long-term changes in the intraocular pressure (IOP) following vitrectomy for rhegmatogenous retinal detachment (RRD), epiretinal membrane (ERM), and macular hole (MH), and to investigate the relationship between the retinal disease and the incidence of late-onset IOP elevation. METHODS: This was a retrospective, observational, comparative study. We reviewed the medical records of 54 eyes of 54 RRD patients, 117 eyes of 117 ERM patients, and 75 eyes of 75 MH patients who underwent 20-, 23- or 25-gauge vitrectomy...

PURPOSE: To analyze the structures of schisis in eyes with hereditary juvenile retinoschisis using en-face optical coherence tomography (OCT) imaging. METHODS: In this retrospective observational study, we reviewed the medical records of patients with hereditary juvenile retinoschisis who underwent comprehensive ophthalmic examinations including swept-source OCT. RESULTS: OCT images were obtained from 16 eyes of nine boys (mean age ± standard deviation, 10...

BACKGROUND: To evaluate demographic, functional, and morphological parameters of idiopathic lamellar macular hole (ILMH). METHODS: Observational longitudinal retrospective study. Optical coherence tomography examinations and corresponding clinical charts of a series of consecutive patients affected by ILMH, between January 2010 and March 2015, from the database of the Department of Ophthalmology of Trento Hospital, Italy, have been collected and examined. Demographic and functional parameters were: age (year), gender (male/female), eye (right/left), lens status, best-corrected visual acuity (BCVA) in logarithm of the minimum angle of resolution (LogMAR)...

AIM: Posterior vitreous detachment (PVD) is a physiological phenomenon due to aging characterized by separation of the vitreous cortex from the retina and may induce a variety of pathological events at the vitreoretinal junction. The aim of this study is to highlight in vivo anatomical and functional changes in early stages of PVD allowing the correct treatment. MATERIAL AND METHODS: Non-consecutive case series; optical coherence tomography (OCT) relies on analyzing the reflectivity of coherent light from different anatomical interfaces within posterior vitreous and retinal histological layers, thus acquiring transverse sections through vitreoretinal interface, sensory retina, retinal pigment epithelium and choroid...

PURPOSE: To determine the outcomes of vitrectomy with scleral imbrication in highly myopic eyes with either myopic traction maculopathy (MTM) or macular hole retinal detachment (MHRD). METHODS: The medical records of 17 patients who had undergone vitrectomy with internal limiting membrane (ILM) peeling and scleral imbrication for MTM or MHRD were reviewed. The best-corrected visual acuities (BCVAs), the axial length, the macular hole (MH) closure rate, and the shape of the posterior segment determined by optical coherence tomography were evaluated...

Graphene has attracted extensive attention in biological and biomedical fields due to its unique physical properties and excellent biocompatibility. We combine graphene field-effect transistors and scanning photocurrent microscopy with microfluidic platforms to investigate electrical signals in mouse retina. Remarkable photocurrent signals were detected from the graphene underneath the optic nerve head (ONH) of the retina, where the electrical activity from this region can modulate the carrier concentration of the graphene and induce local potential gradients...

The indications of point-of-care ultrasound (POCUS) in the management of multiple trauma patients have been expanding. Although computed tomography (CT) scan of the orbit remains the gold standard for imaging orbital trauma, ultrasound is a quick, safe, and portable tool that can be performed bedside. Here we report two patients who had severe eye injuries with major visual impairment where surgeon-performed POCUS was very useful. One had a foreign body injury while the other had blunt trauma. POCUS was done using a linear probe under sterile conditions with minimum pressure on the eyes...

Purpose. The purpose of this study was to determine the long-term changes in the circumpapillary retinal nerve fiber layer (RNFL) thickness following macular hole surgery with internal limiting membrane (ILM) peeling combined with phacoemulsification. Methods. Thirty-eight eyes of 37 patients who had pars plana vitrectomy (n = 36) between 2010 and 2014 were studied. The average thicknesses of the global and the six sectors of the RNFL were determined before and at 1, 3, 6, 12, and 24 (n = 22) months (M) after the surgery by spectral-domain optical coherent tomography...

Introduction. Intravitreal drug injections and implants are generally safe but do carry some risk, from both the procedure itself and adverse effects of the medications. We report a case of an eccentric macular hole after dexamethasone implant (Ozurdex®) administration. Ex vitro force testing was performed to evaluate dexamethasone implant injection force. Methods. Five dexamethasone implant (Ozurdex) applicators were placed 16 mm from a force plate and the force of the injected dexamethasone pellet was recorded in Newtons...

PURPOSE: The true prevalence of retinal detachment and other vitreoretinal disorders in different ethnic groups is not well-established. Understanding differences in vitreoretinal disease prevalence is important to appropriately allocate resources to meet demand where ethnic variation in the community exists. The aim of this study is to provide hospital-based data on the proportion of people with vitreoretinal disorders in the 3 main ethnic groups in the United Kingdom: Caucasian, Afro-Caribbean, and South Asian...

PURPOSE: To investigate the impact of macular pigment (MP) on fundus autofluorescence (FAF) lifetimes in vivo by characterizing full-thickness idiopathic macular holes (MH) and macular pseudo-holes (MPH). METHODS: A total of 37 patients with MH and 52 with MPH were included. Using the fluorescence lifetime imaging ophthalmoscope (FLIO), based on a Heidelberg Engineering Spectralis system, a 30° retinal field was investigated. FAF decays were detected in a short (498-560 nm; ch1) and long (560-720 nm; ch2) wavelength channel...

CASE REPORT: A 14 year-old boy attended our clinic complaining of a scotoma after an accidental exposure to a 10W, 450nm laser beam from a blue-light handheld laser device. Optical coherence tomography confirmed a full thickness macular hole. As visual acuity (VA) remained 20/20 Snellen, observation was decided. Spontaneous closure was confirmed after one month. DISCUSSION: Reckless use of high-power handheld laser devices may induce severe retinal lesions, including full thickness macular holes...

PURPOSE: To evaluate the efficacy of the inverted internal limiting membrane (ILM) flap technique in vitrectomy for macular hole (MH) with retinal detachment (RD) compared with vitrectomy using ILM peeling. METHODS: A retrospective case series study was performed. Twenty-two eyes of 22 patients who underwent vitrectomy for MH with RD and followed-up more than 12 months after the surgery were included in this study. We retrospectively reviewed the medical records of patients who underwent vitrectomy with inverted ILM flap technique or vitrectomy with ILM peeling...

PURPOSE: To report the clinical features, possible associations and treatment outcomes of patients with macular hole after pars plana vitrectomy (PPV) (single or multiple) for rhegmatogenous retinal detachment (RD). METHODS: Retrospective consecutive case series from July 2009 to July 2014. RESULTS: In the 15 study patients, the average time from RD surgery to macular hole diagnosis was 119 days (range: 41-398 months). Possible associations include epiretinal membrane (73%, 11/15 patients), macula-off RD (60%, 9/15 patients), recurrent RD (47%, 7/15 patients), and high myopia (56%, 5/9 patients)...
