Because of that, I try to tape all of my high-risk cases. These include iris injuries, ciliary body trauma, vitreous body detachment, retinal vessel injury, and choroidal rupture.56 Patients with vitreal hemorrhages may present complaining of varying degrees of vision loss and pain. This is a complication of cataract surgery when the technique is done with the intention to preserve the posterior capsule in order to provide support for an intraocular lens. Shoss, Bradley L.; Tsai, Linda M. Postoperative care in cataract surgery, Current Opinion in Ophthalmology: January 2013 - Volume 24 - Issue 1 - p 66-73 doi: 10.1097/ICU.0b013e32835b0716. 18:395-402. Penlight examination will reveal larger hyphemas, while smaller hyphemas and microhyphemas will require a slit lamp evaluation for diagnosis. encountered beneath doi:10.1016/j.ophtha.2016.09.027, Grzybowski A, Kanclerz P. Do we need day-1 postoperative follow-up after cataract surgery?. Emerg Med Clin North Am 1995;13:521-538. Experimental central retinal artery occlusion. A pocket of Patients with small conjunctival defects (smaller than 1 cm) typically will heal without surgical intervention. In addition, you could encounter a cataract thats adherent to the posterior capsule, preventing you from removing it without causing a tear in an area of weakness in the posterior capsule., A posterior chamber rupture can also take you by surprise when youre operating on a patient who has been treated for retinal disease, he points out. 92. For instance, corneal epithelial defects and iris, lens, posterior segment, globe, and orbital injuries often accompany traumatic hyphemas.39 The presence of hyphema in the absence of trauma should prompt investigation for an underlying blood dyscrasia (e.g., leukemia), coagulopathy, or melanoma of the iris. 37. Dr. Lee emphasizes that you shouldnt stop irrigation and pull the phaco tip out of the eye right away. The only exception is if I have an IOL that dislocated posteriorly; then I certainly want to leave the patient aphakic. Medical interventions aimed at reducing intraocular pressures (including mannitol, acetazolamide, topical beta-blockers, etc.) Because the orbit is a closed space, any rise in intraorbital contents (e.g., retrobulbar hematoma) or orbital volume loss (e.g., orbital fracture) will result in an elevation of intraorbital pressure. It is important to exclude elevated IOP in the presence of hyphema or retrobulbar hemorrhage. Airbag-related ocular trauma victims deserve careful ocular examination, including pH measurement, slit lamp examination, fluoroscein staining, IOP measurement, and a funduscopic examination. Despite this concern, authors still recommend copious irrigation of all chemical eye injuries, even when exposure to metallic sodium, metallic potassium, or yellow or white phosphorous is known. 49. facilitate Can J Ophthalmol 1993;28:325-327. limbus. Arch Otolaryngol 1973;98:366-369. haze obscures iris Referral to a retinal specialist is a good idea after any of these cases. If a patient is moving around, even with anesthesia, that alone may be the reason for the tear, he says. 1268-1277.

In contact lens users, there is a higher incidence of Pseudomonal species superinfection, hence antibiotic therapy should provide anti-Pseudomonal coverage (e.g., 0.3% tobramycin ophthalmic drops, 2 drops every 4 hours).26,27 Contact lens users should be instructed to avoid wearing contact lenses until their defects have completely healed. The initial treatment for a majority of ocular chemical injuries is immediate, copious irrigation.112 There is no therapeutic difference between ocular irrigation of chemical injuries with normal saline, normal saline with bicarbonate, lactated Ringers, and balanced salt solutions.113 The lids should be retracted during irrigation and the stream of irrigating fluid should be directed onto the globe and conjunctival fornices. Traumatic hyphema in a defined population. Flare resembles dust specks floating in a bright, sunlit room, whereas the red blood cells that form a microscopic hyphema will look like brown dust.6. Advance the Kelly WM, Paglen PG, Pearson JA. Cataract in the Adult Eye Preferred Practice Pattern. Anatomy. He or she may place air or other gas into your eye to help the retina stay in its proper position. 112. Were going to fall behind. You have to block out all these self-defeating thoughts, deal with the situation, and make the best decisions you can under the circumstances to achieve the best result you can for your patient.. Cochrane Database of Systematic Reviews 2017, Issue 2. Subperiosteal orbital hematoma: Visual recovery following delayed drainage. Additionally, physicians may also prescribe a two-to-four-week regimen of topical cyclosporine. The most significant complication of corticosteroid use is increased intraocular pressure (IOP), which occurs more frequently in younger, highly myopic patients or those with glaucoma. For most people, cataract surgery goes smoothly. 60. The use of depolarizing paralytic agents such as succinylcholine to facilitate endotracheal intubation in the setting of globe rupture is controversial. Philadelphia, PA: JB Lippincott; 1994:22-24. Then I just clean up the vitreous in the anterior chamber and clean up the anterior vitreous in back of the posterior capsule. A detailed history aids in the assessment of injury severity and guides subsequent patient evaluation. region with sterile Once the diagnosis of an acute OCS is made, immediate lateral canthotomy and cantholysis is indicated within one hour of injury and ocular dysfunction 82-85 (See Table 3.). necessary to identify Eye 1993;7:468-471. Emergency physicians must have a comprehensive understanding of ocular anatomy, pertinent patient history, and physical examination findings which will Patients who have increased risk of postoperative inflammation include those with longer operative times, period surgery and extensive procedures at a younger age. Am J Ophthalmol 1980;89:593-597. Inflammatory effects of cataract surgery are also the targets of topical corticosteroids. Chen, Sherleen H., et al. Does Running Prevent Coronary Artery Disease? Sympathetic ophthalmia is thought to arise from sensitization of the immune system to uveal antigens.99 These patients typically complain of bilateral eye pain, redness, photophobia, and decreased vision. Metal splinters from hammering and glass splinters from shattering glass may enter the eye painlessly.101 The initial ocular examination may appear deceptively benign, revealing only slight erythema and local discomfort. Then take a moment to set up the correct instrumentation for vitrectomy and use Triesence or Kenalog (triamcinolone, Bristol-Myers Squibb) to stain the vitreous. The eyelids should be assessed for movement, swelling, ecchymoses, lacerations, margin integrity, or occult foreign bodies. The larger the hyphema, the worse the prognosis. chamber, but less than [15] The use of NSAIDs is based on provider discretion, as evidence of the benefits and risks continues to emerge. The anterior chamber may reveal proteinaceous debris (flare), red blood cells (hyphema), or purulent exudate (hypopyon). Emergent management involves systemic, topical, and intraocular antibiotic therapy. Lacerations that extend through all layers of the eyelid should be referred to an ophthalmologist, as these injuries are a sign of potentially more serious injury such as globe penetration. The lens placement may be depend on the capsular support if can be placed in the bag, sulcus or for an extensive tear and lack of support it may need anterior chamber lens. J Accid Emerg Med 1997;14:40-41. Packer AJ. The anterior and posterior chambers are filled with transparent, protein-free aqueous humor, which provides oxygen and nutrients to the cornea and lens. Referring a patient to a retinal specialist in the presence of a retained nucleus can be critical because of the risk of a retinal detachment and the probability of needing a full vitrectomy., In terms of retained cortical material thats not as dense and likely to dissolve upon observation, you can observe those patients closely, as long as you have a good view on a dilated exam, he adds. the LCT. [15] These drugs act to increase mucin secretion into the tear film, thus stabilizing tears and preserving their ocular protective effects. Arch Ophthalmol 1983;101:919-924. [25][26][27][28] In those with a miotic pupil, pilocarpine 1% or 2% may be added for an additional 1-2 weeks to augment pupillary healing postoperatively. 24. If youre not able to capture the optic of the IOL and need to place the optic in the sulcus, then of course you have to make IOL power adjustments, he says. A teardrop-shaped pupil is suggestive of globe rupture, with the apex of the teardrop pointing to the rupture site.5 Each pupil should be assessed for direct and consensual response to light stimulation (pupillary light reflex). Dr. Grayson, like Dr. Lee, doesnt think implantation of an IOL after a posterior chamber rupture is essential. The lens is off-center, yet still remains partly within the pupillary aperture. getting soap or shampoo in the eye. Patients typically present with ocular pain, proptosis, afferent pupillary defects, and diminished vision. Trauma to the brain or eye can cause a fixed pupil. Foreign bodies should be removed only if the entire foreign body can be visualized, as one end may have penetrated the globe or orbit. , How is Coloboma Diagnosed in Adults and Children? Lens Subluxation and Dislocation. Fleishman JA, Beck RW, Hoffman RO. Krausen AS, Ogura JH, Burde RM, et al. Another complication patients often deal with following cataract surgery is Dry eyes.

Grayson and Wallace have no financial interest in the products discussed. If the anterior vitreous face is intact and not vitreous is noted in the anterior chamber, phacoemulsification may be continued. Survey Ophthalmol 1997;41: Finklestein M, Legmann A, Rubin PAD. Br J Ophthalmol 1965;49:472-477. Ophthalmology 1996;103:1798-1803. Patients with moderate to severe injuries (grades II-IV) warrant emergent ophthalmologic assessment and, likely, hospitalization. While the cornea is often the area of focus, additional areas such as the eyelids and adnexal structures often are damaged. Visual field testing will detect disorders affecting the retina, optic nerve, optic chiasm, and visual cortex. severed (. [16] The effects of topical corticosteroids on postoperative outcomes include decreasing post-surgical incidence of CME and reducing inflammation such as lid edema, lid injection, conjunctival injection, corneal edema, ciliary flush, and anterior chamber cells. But if youre doing an IOL capture, Id say you need to only decrease the power about a quarter of a diopter.
