Grand Rounds Conference Eric Downing MD University of Louisville Department of Ophthalmology and Visual Sciences Subjective CC: “Can’t control my eye movements” HPI: 41M fell off a forklift suffered a concussion. Complains of intermittent diplopia, blurry vision, and uncontrollable blink reflex. History POH: none PMH: none Eye Meds: none Meds: Cyclobenzaprine, Nortriptyline Objective VA: Pupils: IOP: EOM: OD 20/70 3->1 24 OS 20/40 3->1, no rAPD 23 (squeezing) Clinical Video Refraction M -1.75 +0.25 x 005 -2.00 +0.25 x 170 20/20 20/20 C -0.75 +0.25 x 016 -0.75 +0.75 x 010 20/20 20/20 Objective SLE: All WNL DFE: All WNL Imaging: CT head: WNL Additional example Assessment 41M with h/o anxiety disorder, s/p concussion with spastic eye movements, inappropriate accommodation, pseudomyopia, and horizontal diplopia at near > distance x 6 months. Dx: Spasm of the near reflex Plan Referral to Neuro clinic Trial of Atropine daily with reading glasses Two week follow up Patient reported no alleviation of symptoms with Atropine Addition of trial of Phospholine Iodide Follow up again in 3 weeks Convergence Spasm First described by Cogan in 1955 Inappropriate occurrence of the near triad 1. 2. 3. Convergence Miosis Accommodation Diagnosis 1. 2. 3. Intermittent episodes of sustained maximal convergence Accommodative spasm Pupillary constriction Pathophysiology Primarily a functional etiology, associated with somatization disorders, such as hysteria or neurosis Organic causes: encephalitis, tabes, labyrinthe fistulas, Arnold-Chiari malformation, posterior fossa neurofibroma, trauma, or pituitary adenomas Organic Jampel localized the near triad to Brodmann areas 19 and 22, but also there are at least 3 areas involved in the near reflex: 1. 2. 3. Cerebral cortex Pretectum of the midbrain Oculomotor nuclear complex Epidemiology Reported occurrence is very variable, and ranges from 0.1-1%. Most patients are young in age 2-3/1 Female to male predominance Occurrence of visual symptoms occurs in ~16% of patients with conversion disorder History & Physical History Decreased VA Blurry vision/horizontal diplopia, especially at near Eye strain HAs Physical Variable esotropia, convergence overaction Accommodative spasm Miosis Work-up Imaging and lab studies indicated in cases that don’t have an antecedent event, other focal neurologic signs, or absence of psychiatric history Treatment Atropinization with reading glasses, sometimes for up to one year Botox injection Miotics, such as Phopholine Iodide Antidepressants +/- psychological counseling Minus lenses Placebo drops Retrospective study 17 pts 3 resolved with treatment 14 were over-corrected 7 needed continued treatment 7 saw no benefit, and discontinued treatment Case report 10 year old boy with convergence spasm Given phospholine iodide and phenylephrine Resolution within 8 weeks Similar reports by Moore and Stockbridge 7 yr old girl with 10.5 diopters of pseudomyopia Initial therapy with Atropine and reading glasses with no resolution She was placed on Sertraline and Diazepam, and saw resolution within one month. Summary The varied range of disease entities and nomenclature makes it difficult to present a unified etiology Variety of cases presented under the umbrella of accommodation abnormalities and convergence disorders. With and without miosis With and without gaze paralysis of vertical gaze With and without accommodative spasm Summary Varied treatments leads one to the conclusion that the natural history of the disease may be toward spontaneous resolution.
