Dexamethasone intravitreal implants (0.7 mg) (Ozurdex, Allergan Inc., Madison, NJ) are FDA approved\nfor managing macular oedema (ME) of retinal vein occlusion (RVO). The major complications associated with\nintravitreal Ozurdex implant include increased intraocular pressure and cataract progression. In regard to the\noccurrence of retinal complications, we report an unusual intravitreal Ozurdex implantation-related acute retinal\nnecrosis (ARN).\nCase presentation: A 45-year-old immunocompetent woman with a history of encephalitis presented with\nphotophobia, redness, floaters, and rapidly decreased vision in her left eye. Three and six months ago, she received\ntwo doses of intravitreal Ozurdex implant for ME of RVO. Clinical evaluation, including slit-lamp biomicroscopy,\nretinal photography, and fluorescein angiography, revealed anterior chamber cells, granulomatous keratic\nprecipitates, cells in the vitreous, optic disc oedema, occlusive retinal vasculitis, scattered retinal haemorrhages, one\nquadrant of peripheral white areas with retinal necrosis, optic disc and vessels fluorescein staining, and retinal\nnonperfusion zones. All the above clinical manifestations showed an ARN. Herpes simplex virus was detected in the\naqueous and vitreous humour by quantitative polymerase chain reaction testing. Intravenous acyclovir 500 mg tid\nfor 7 days followed by oral valcyclovir was immediately performed for ARN. At 4 months, the patientâ??s condition\nimproved without retinal detachment, and the best-corrected visual acuity remained stable at 0.3.\nConclusions: ARN might represent a risk of Ozurdex administration....
To compare the clinical outcomes of transepithelial photorefractive keratectomy (TPRK) with\nfemtosecond laser-assisted in situ keratomileusis (FS-LASIK) for correction of high myopia.\nMethods: In this prospective, non-randomised, cohort study, 85 eyes of 46 patients treated with TPRK and 80 eyes\nof 42 patients treated with FS-LASIK were included. All eyes were highly myopic (spherical equivalent refraction.....................
To investigate different tamponade effects of intravitreal silicone oil (SO) and sterilized air on macular\nvasculature and structure after successful retinal repair for macular-on rhegmatogenous retinal detachment (RRD) patients.\nMethod: 21 eyes (21 patients) with macular-on RRD underwent single pars plana vitrectomy following intravitreal SO or\nsterilized air (Gas) tamponade. Optical Coherence Tomography (OCT) and angiography were used to evaluate retinal layer\nthickness and flow density (FD) changes throughout the observation period of 12 weeks. Retinal layers were segmented\ninto 7 sets: NFL, GCL....................
To determine the effect of various factors to the preservation rate of the conjunctival layer\nborderlines of glaucomatous eyes treated with anti-glaucoma eye drops.\nMethods: Anterior segment optical coherence tomography (AS-OCT) images of the bulbar conjunctiva of 328\neyes were analyzed with and without anti-glaucoma eye drops to quantify the preservation rates of the\nconjunctival layer borderlines.\nResults: More anti-glaucoma eye drops and a longer duration of administration were associated with lower\npreservation rates of the borderlines between both the conjunctival stroma/Tenonâ??s capsule.....................
The Heimann-Bielschowsky phenomenon (HBP) is an underrecognized condition characterized by\nslow, pendular, vertical oscillations of the eye accompanying monocular vision loss. Hypotropic dissociated vertical\ndeviation (DVD) is another rare condition induced by asymmetric visual input. This report documents a rare case of\nHBP with hypotropic DVD.\nCase presentation: This report describes a case of a 58-year-old woman with HBP and hypotropic DVD, having\nsuffered monocular vision loss in the left eye due to blunt trauma at the age of 10. Preoperatively, she was\northophoric at near fixation and demonstrated an intermittent, slow hypotropia of the left eye upon distance\nfixation that never rose above the midline. She underwent a 7mm recession of the inferior rectus muscle in the left\neye. After surgery, intermittent, downward drifts became constant vertical oscillations at both distance and near\nfixation.\nConclusions: This case describes the clinical manifestation of an eye movement disorder related to prolonged\nmonocular vision loss....
This study aimed to evaluate the effect of the size of the dots in random-dot stereograms on the\nresults of stereoacuity measurements.\nMethods: A stereopsis measurement system was created using a phoropter and two 4 K smartphones. Three dot.......................
