Abstract
In the management of orbital disorders and defects, minimally invasive surgical approaches have become increasingly efficient for their reduction of operative trauma and access without compromise of therapeutic benefit or diagnostic yield. Various approaches have focused on bone- and canthal-sparing techniques and concealed and small skin incisions. We review the current state of knowledge of procedures to enter the orbit via the conjunctiva. Any quadrant of the orbit can be accessed via the conjunctiva. Surgical incisions involve the orbital palpebral, forniceal, and bulbar conjunctiva. According to the location, nature, and size of the lesion, the transconjunctival orbitotomy can be used as a single procedure, in combination with a caruncular approach or as an adjunct in a multidisciplinary procedure for lesions extending deep into or outside the orbit. The working space and field of operating view can be expanded by releasing the horizontal tension of the eyelid with a lateral cantholysis, lateral paracanthal blepharotomy, or medial lid split procedure. Complications related to the conjunctival incision are reduced to dry eye disease.

Surgical Antimicrobial Prophylaxis in Patients of Neonatal and Pediatric Age Subjected to Eye Surgery: A RAND/UCLA Appropriateness Method Consensus Study. Antibiotics (Basel) 2022; 11:antibiotics11050561. [PMID: 35625205 PMCID: PMC9137626 DOI: 10.3390/antibiotics11050561] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/14/2022] [Accepted: 04/19/2022] [Indexed: 01/25/2023] Open
Abstract
Ocular surgery encompasses a wide range of procedures, including surgery of the tear ducts, eyelid, cornea and conjunctiva, lens, ocular muscle, and vitreoretinal and iris surgery. Operations are also performed for the removal of tumors, repairs of ocular trauma and, finally, corneal transplantation. Antibiotic prophylaxis for the prevention of surgical site infections (SSIs) in ocular surgery is a complex field in which shared lines of action are absent. In light of the scarcity of shared evidence in the use of ocular antimicrobial prophylaxis for the pediatric population, this consensus document aims to provide clinicians with a series of recommendations on antimicrobial prophylaxis for patients of neonatal and pediatric age undergoing eye surgery. The following scenarios are considered: (1) intraocular surgery; (2) extraocular surgery; (3) ocular trauma; (4) ocular neoplasm; (5) ocular surface transplantations; (6) corneal grafts. This work has been made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies and represents, in our opinion, the most complete and up-to-date collection of recommendations regarding clinical actions in the peri-operative environment in eye surgery. The application of uniform and shared protocols aims to improve surgical practice, through the standardization of procedures, with a consequent reduction of SSIs, also limiting the phenomenon of antimicrobial resistance.

Povidone iodine treatment is deleterious to human ocular surface conjunctival cells in culture. BMJ Open Ophthalmol 2020; 5:e000545. [PMID: 32995498 PMCID: PMC7497553 DOI: 10.1136/bmjophth-2020-000545] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 08/07/2020] [Accepted: 08/19/2020] [Indexed: 12/27/2022] Open
Abstract
Objective To determine the effect of povidone iodine (PI), an antiseptic commonly used prior to ocular surgery, on viability of mixed populations of conjunctival stratified squamous and goblet cells, purified conjunctival goblet cells and purified conjunctival stromal fibroblasts in primary culture. Methods and analysis Mixed population of epithelial cells (stratified squamous and goblet cells), goblet cells and fibroblasts were grown in culture from pieces of human conjunctiva using either supplemented DMEM/F12 or RPMI. Cell type was evaluated by immunofluorescence microscopy. Cells were treated for 5 min with phosphate-buffered saline (PBS); 0.25%, 2.5%, 5% or 10% PI in PBS; or a positive control of 30% H2O2. Cell viability was determined using Alamar Blue fluorescence and a live/dead kit using calcein/AM and ethidium homodimer-1 (EH-1). Results Mixed populations of epithelial cells, goblet cells and fibroblasts were characterised by immunofluorescence microscopy. As determined with Alamar Blue fluorescence, all concentrations of PI significantly decreased the number of cells from all three preparation types compared with PBS. As determined by calcein/EH-1 viability test, mixed populations of cells and fibroblasts were less sensitive to PI treatment than goblet cells. All concentrations of PI, except for 0.25% used with goblet cells, substantially increased the number of dead cells for all cell populations. The H2O2 control also significantly decreased the number and viability of all three types of cells in both tests. Conclusion We conclude that PI, which is commonly used prior to ocular surgeries, is detrimental to human conjunctival stratified squamous cells, goblet cells and fibroblasts in culture.

J Pediatr Ophthalmol Strabismus 2019; 56:354-359. [PMID: 31743402 DOI: 10.3928/01913913-20190808-01] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Accepted: 08/07/2019] [Indexed: 11/20/2022]
Abstract
PURPOSE To characterize the practice patterns of pediatric ophthalmologists regarding infection prophylaxis for strabismus surgery and timing of the first postoperative visit. METHODS A ten-question multiple-choice, close-ended questionnaire was e-mailed to members of the American Association for Pediatric Ophthalmology and Strabismus listserv. Survey responses were summarized using frequencies and percentages. Univariable tests of association between prophylactic measures and surgeons reporting a prior episode of postoperative cellulitis or endophthalmitis were performed. RESULTS Three hundred eighty pediatric ophthalmologists completed the survey. Most ophthalmologists instill 5% povidone-iodine solution during surgical preparation (88.4%), use topical antibiotics with or without steroids at the conclusion of surgery (90%), and prescribe oral or topical antibiotics postoperatively (85.5%). Eighty-five percent of strabismus surgeons routinely see patients for the first postoperative visit within the first week, although there is no consensus as to which day is preferred. Responders previously reporting experience with a postoperative infection were more likely to use intraoperative intravenous antibiotics (P = .002) and Tegaderm tape (3M, St. Paul, MN) or other adhesive drape to isolate the eyelids/eyelashes (P = .047). CONCLUSIONS A common practice pattern appears to exist regarding the use of 5% povidone-iodine solution in surgical preparation, application of topical antibiotics at the end of surgery, and a postoperative regimen of topical antibiotics/steroids. There is no prevailing practice pattern regarding the timing of the first postoperative visit. Previous experience with postoperative cellulitis or endophthalmitis may lead to the adoption of more formidable infection prophylaxis measures such as intravenous antibiotics prior to surgery.

Abstract
An extensive literature review of various types of infections following strabismus surgery was facilitated by using the search engines PubMed and Google Scholar. In both search engines, the phrases "infection following strabismus surgery," "infection strabismus surgery," "complications of strabismus surgery," "endophthalmitis strabismus surgery," and "strabismus scleral perforation" were used for the review. The type of infection, surface involved, and site of the infection determined the type of therapy. Infections involving deeper tissues, such as periocular infection or orbital cellulitis, required systemic therapy. Sub-Tenon's abscesses required incision and drainage, as well as systemic antibiotics. The development of endophthalmitis following strabismus surgery was rare, but was usually devastating to the visual result. Symptoms of an adverse intraocular condition began by mean postoperative day 3, but the definitive diagnosis and treatment of endophthalmitis was not made until mean postoperative day 6. Despite early detection of this latter type of infection and early surgical intervention with vitreous paracentesis and intraocular injection of antibiotics, the visual result was extremely poor in more than two-thirds of the reported cases. Although there is no known way to truly prevent all infections following strabismus surgery, several techniques may be prudent for the strabismus surgeon to adopt to decrease the bacterial load and minimize the risk of infection. The surgeon should be encouraged to consider preoperative use of povidone-iodine on the operative field and avoid scleral perforation during surgery.

Abstract
BACKGROUND AND PURPOSE Good surgical results following strabismus surgery depend on several factors. In this article, detailed steps for planning strabismus surgery will be reviewed for basic horizontal strabismus surgery, vertical, and oblique muscle surgeries. The thought process behind each case will be presented to help in selecting the best surgical approach to optimize postoperative results. PATIENTS AND METHOD The surgical planning for strabismus will be developed with clinical examples from easy cases to more complex ones. Preoperative pictures of the ocular alignment are an integral part of planning surgery and help in documenting the strabismus before and after surgery. RESULTS Three cases of strabismus cases will be reviewed with several key factors for planning surgery, including visual acuity, refractive error, potential for stereovision, and risk of postoperative diplopia. The most important factor is accurate orthoptic measurements. The surgical planning for each patient is detailed along with preoperative pictures. CONCLUSION Strabismus surgery results can be improved by careful preoperative planning. The surgeon has the ability to discern potential pitfalls that can alter the surgical outcome. Surgical planning allows a dedicated time of reflection before surgery, foreseeing potential problems, and avoiding them during the surgery.
