Teaching of the lateral tarsal strip technique using a duct tape simulation
A lateral tarsal strip is a surgical procedure commonly used in oculoplastics for the repair of entropion and ectropion. A lateral tarsal strip involves correction of horizontal lid laxity with incision at the lateral canthus. Residents may have difficulties with suture placement of the tarsal strip in the periosteum. In an effort to facilitate the surgical teaching of this technique, we propose a straightforward surgical simulation to reproduce the technique. A plastic skull model, standard duct tape, surgical instruments, and suture are needed.Role of multimodal ocular imaging in Alport syndrome
A 19-year-old man with Alport syndrome presented with diminution of vision in his left eye. Slit-lamp biomicroscopy showed an early anterior lenticonus with an anterior subcapsular cataract in his right eye (Fig. 1A) and a dense anterior polar and anterior subcapsular cataract in his left eye (Fig. 1B). Fundus photography revealed central perimacular dot-and-fleck retinopathy with a dull macular reflex or lozenge in both eyes (Fig. 1C, 1D). The flecks were better visualized on red-free imaging as a ring of fine white stippling around the macula (Fig.IgG4-related orbital disease
A 67-year-old man presented with a 3-week history of diplopia and left ocular pain. Examination showed limitation of abduction of the left eye. Computed tomographic scan demonstrated a soft tissue density mass in the ethmoid sinus (yellow arrow) with extension into the left orbit and infiltration of the medial rectus muscle (Fig. 1A). Incisional biopsy revealed a dense lymphoplasmacytic infiltrate (Fig. 1B), storiform fibrosis, and obliterative phlebitis (yellow arrow, Fig. 1C). Immunohistochemistry was positive for immunoglobulin 4 (IgG4; IgG4+ cells > 30/hpf and IgG4:IgG ratio > 40%) (Fig.A practical approach to slit-lamp smartphone photography
Several approaches to smartphone anterior segment photography that involve purchasing an adapter to attach to the slit lamp have been described in the literature. Given the frequent updates in sizes and shapes of smartphones, a practical stepwise approach to capturing high-quality images without the need for an adapter is essential. First, the illumination is set to be diffuse, using the slit-lamp integrated diffuser (Fig. 1A, 1B). The camera flash is turned off, and the slit lamp is brought into focus on the anterior segment.Retinal racemose hemangioma characterization with multimodal imaging
Racemose hemangioma is an arteriovenous vascular malformation in which the retinal vessels appear abnormally dilated. The arteries are connected with the veins directly, without the interposition of a capillary network (Fig. 1A), forming a fragile vascular mass with turbulent flow that is predisposed to thrombosis phenomena. The fluorescein angiography (Fig. 1B) shows filling of the malformation without exudation. The optical coherence tomography and the optical coherence tomography-angiography en face (Figs.Assistant-controlled directional chandelier
Chandelier endoillumination has become common everyday practice for most vitreoretinal surgeons. The assistant-controlled directional chandelier is a solution to controlling, minimizing glare of, and directing the light when using a chandelier endoillumination device (Video 1, available online). With the use of readily available items within a vitreoretinal operating room setting, the Luer connector is attached to the light pipe with adhesive dressing (A). Approximately 6 mm of residual light pipe is left exposed to stop the assistant from inadvertently advancing the light pipe too deeply into the eye (B).Corneal metallic particles after cataract surgery are safe in magnetic resonance imaging
On close inspection, tiny metallic particles are visible in all corneal incisions after cataract surgery (arrows). They appear to occur after passing cannulas or other instruments through the incisions. The presence of these particles was documented prior to undergoing magnetic resonance imaging (MRI) in 3 patients (Fig. 1A–C). No adverse events occurred during the MRI, and there was no visible artifact on the MRI images (Fig. 1D, axial T2) in the plane of the incisions. These particles appear to be innocuous and do not preclude MRI studies.Commotio retinae secondary to fragmented intraorbital pellets
A 20-year-old man presented with multiple facial gunshot injuries. Visual acuities were 20/20 each eye, with full color vision and normal pupillary responses. Examination showed subconjunctival hemorrhage, mild anterior chamber inflammation, extensive commotio retinae involving the macula, and inferior retinal hemorrhages (Fig. 1A). Computer tomography (Figs. 1B–D) showed orbital emphysema and multiple fragmented left extraconal and intraconal pellets—one in close proximity to the posterior aspect of globe, adjacent to the optic nerve.Retinal vasculitis after intravitreal injection of brolucizumab
An 82-year-old man with age-related macular degeneration presented with painful vision loss in the right eye 42 days after his third brolucizumab injection (Beovu, Novartis, Basel, Switzerland). Visual acuity was light perception (baseline, 20/150). Examination revealed moderate to severe vitritis, arterial sheathing, diffuse arterial and venous narrowing, and perivenular hemorrhages (Fig. 1A,1B). Fluorescein angiography demonstrated extensive arterial and venous filling defects with peripheral nonperfusion (Fig.Retinal crystalline lesions in pseudoxanthoma elasticum
An 11-year-old healthy boy was evaluated for incidental retinal crystalline lesions. Visual acuity was 20/20 in both eyes. Fundus examination of the right (A) and left (B) eyes demonstrated multiple crystalline bodies (blue arrows) scattered throughout the midperipheral and peripheral retina, a peau d'orange pattern of retinal pigment epithelial (RPE), alterations in the temporal retina (white arrow), and angioid streaks (yellow arrow) around the optic nerve on fundus autofluorescence imaging (C).Management of a large metal intraocular foreign body
A 49-year-old man had been seen 1 month prior by a general ophthalmologist for a healing corneal abrasion. On examination, there was a dense vitreous hemorrhage and a subtle iris transillumination defect suspicious for an occult intraocular foreign body (IOFB; Fig. 1A). A computed tomography scan confirmed an IOFB that extended from the inferior posterior iris to the posterior pole (Fig. 1B). Intraoperatively, the traumatic cataract was removed along with the ruptured capsular bag (Video 1, available online).Management of a dislocated 3-piece intraocular lens with an iris prosthesis in situ
A 33-year-old man with a past injury of the left eye involving iris loss and choroidal rupture in 2002, presented with 1-month history of spontaneous blurry vision. On examination he had a dislocated 3-piece Ophtec (Netherlands) intraocular lens (IOL) in the vitreous with an iris prosthesis (Human Optics, Germany) dislocation sutured at 9:00 o'clock and poorly attached at 3:00 o'clock (Supplementary Video 1). The already kinked IOL was cut and explanted (A), and a secondary IOL inserted and fixated to the sclera behind the iris prosthesis using a Yamane technique (B).Secondary vasoproliferative tumor in adult-onset Coats disease
A 20-year-old woman noted a 1-month history of floaters in her left eye. Ultra-widefield multicolor imaging and fluorescein angiography (Figure A, B) showed classic findings of Coats disease (telangiectasia, exudation, subretinal fluid, and peripheral nonperfusion) and an additional yellow-red dome-shaped mass of 3 mm thickness that corresponded to a secondary vasoproliferative tumor encircled by gravitating lipid exudation. Coats disease usually occurs in children but can affect older patients.Third nerve palsy due to influenza A infection
A previously healthy 38-year-old woman presented with new onset left ptosis and diplopia. Two days prior, she developed nasal congestion, cough, fever, and myalgias. Examination revealed left ptosis and a limitation of elevation, depression, and adduction of the left eye (50% of normal). Pupils were equal sizes and reactive to light, and the remainder of the neurological examination was normal. Magnetic resonance imaging with gadolinium revealed mild enhancement (Fig. 1A) and an increased size and T2 signal (Fig.
