Objective: To examine the reliability of clinical examination and in vivo confocal microscopy (IVCM) in distinguishing ocular surface squamous neoplasia (OSSN) from benign conjunctival lesions.Design: Case-control study.Participants: Sixty individuals…
Contact lenses can deliver glaucoma drugs for a month
Scientists from Massachusetts have created a contact lens that will deliver controlled amounts of medicine directly into the eyes of glaucoma patients continuously for up to a month.
Lateral Rectus Superior Compartment Palsy – Corrected Proof
Purpose: To employ magnetic resonance imaging (MRI) to seek evidence of compartmental lateral rectus atrophy consistent with a lesion involving selective denervation of only 1 of the 2 neuromuscular compartments of the lateral rectus.Design: Prospective observational case-control series.Methods: At a single institution, surface coil coronal MRI was obtained at 312 μm resolution in quasi-coronal planes 2 mm thick throughout the orbit in 20 normal volunteers and 18 patients with unilateral lateral rectus palsy fixated monocularly on a target placed in central gaze. Maximum cross sections and posterior volumes of the superior and inferior lateral rectus compartments were computed and correlated with clinical (Read more...)
HLA-DR, DQ Class II DNA Typing in Pediatric Panuveitis and Tubulointerstitial Nephritis and Uveitis (TINU) – Accepted Manuscript
Abstract: Purpose: To describe chorioretinal lesions in pediatric uveitis that are strongly associated with the HLA-DR,DQ Class II type associated with tubulointerstitial nephritis and uveitis (TINU).Design: Retrospective, observational case series.Methods: Results: Fourteen of the 15 patients (93%) with otherwise unexplained pediatric panuveitis typed HLA-DRB1*01-HLA-DQB1*05. Eleven of 15 (73.3%) had bilateral sharply demarcated, usually inferior, 200-300 micron spots of chorioretinal atrophy, and 4 of 15 (27.7%) had bilateral clusters of 500-750 micron poorly defined orange choroidal lesions without overlying atrophy of the retinal pigment epithelium. None had interstitial nephritis. Four of the 6 definite TINU cases had Class II typing and (Read more...)
Comparison of Wide-Field Fluorescein Angiography and Nine-Field Montage Angiography in Uveitis – Accepted Manuscript
Abstract: Purpose: To qualitatively and quantitatively compare Optos© fundus camera fluorescein angiographic images of retinal vascular leakage with 9-field montage Topcon© fluorescein angiography (FA) images in patients with uveitis. We hypothesized that Optos images reveal more leakage in uveitis patients.Design: Retrospective, observational case series.Methods: Images of all uveitis patients imaged with same-sitting Optos FA and 9-field montage FA during a 9 month period at a single institution (52 eyes of 31 patients) were graded for the total area of retinal vascular leakage. The main outcome measure was area of fluorescein leakage.Results: The area of apparent FA leakage was greater in (Read more...)
Comparison of refractive stability after non-toric versus toric intraocular lens implantation during cataract surgery – Accepted Manuscript
Abstract: Purpose: To compare refractive state changes in eyes implanted with toric intraocular lenses (IOLs) versus non-toric IOLs, after cataract extraction.Design: Retrospective, comparative.Methods: In a single-institution, 121 eyes underwent phacoemulsification and implantation with either non-toric IOLs (AcrySof® IQ SN60WF) or toric IOLs (AcrySof® Toric IOL). The spherical value, cylindrical value, spherical equivalent (SE) of refractive error, and visual acuity were measured preoperatively and 1, 3, and 6 months after surgery. Main outcome measures were the pattern of changes of spherical, cylindrical, and SE values based on postoperative time, between different IOL types.Results: The groups included patients who underwent surgery with (Read more...)
