6 Blindness with Blepharoplasty and Injectables
Summary
Blindness is fortunately a rare, yet devastating, complication that may occur following blepharoplasty or filler injections. Knowledge of the etiology and risk factors is key to preoperative preparation and adoption of appropriate measures to minimize risk and ensure patient safety. Avoidance strategies include: reduction in risk factors, optimization of the patient’s health, surgical technique in the operating room, and close postoperative monitoring. Early recognition and timely management are key for a successful resolution of blindness. A variety of medical and surgical techniques have been described and should be tailored to tackle the initial insult. This chapter explores the incidence, avoidance strategies, and management of blindness following blepharoplasty or filler injections.
6.1 Incidence
Blindness is fortunately a rare, yet devastating, complication that may occur following blepharoplasty or filler injections. Every physician operating on the eyelids or injecting fillers in the periorbital should be aware of this risk, take precautions to minimize it, and be prepared for emergency treatment.
The first report of blindness following blepharoplasty was published in 1962 by Hartmann et al, and since then, there have been several other publications discussing current strategies for prevention, diagnosis, and management of this complication (Table 6-1). The incidence of blindness following blepharoplasty was first published by DeMere et al in 1974. The authors surveyed 3,000 ophthalmologists and plastic surgeons in the United States, who reported 40 cases of blindness out of the 98,514 eyelid operations, an incidence of approximately 0.04%. Hass et al surveyed 237 members of the American Society of Ophthalmic Plastic and Reconstructive Surgery in 2004. The authors collected reports of 269,433 blepharoplasties, with 48 cases of orbital hemorrhage associated with temporary blindness and 12 cases of orbital hemorrhages associated with permanent blindness. The incidence of temporary blindness was 0.0425%, and that of permanent blindness was 0.0045%. In 2011, we published a large international study where we surveyed a total of 648 members of the American Society for Aesthetic Plastic Surgery (ASAPS) and 72 members of the British Association of Aesthetic Plastic Surgeons (BAAPS). Of the 752,816 blepharoplasties performed by the respondents, blindness was reported in 39 cases: 25 permanent and 14 temporary. The overall incidence of blindness following blepharoplasty was 0.0052% (5 in 100,000, or 1 in 20,000); the incidence of temporary blindness was 0.0019% (2 in 100,000, or 1 in 50,000) and that of permanent blindness was 0.0033% (3 in 100,000, or 1 in 30,000). A summary of the studies reporting the incidence of blindness following blepharoplasty is presented in Table 6-2.
Blindness is also seen following injection of fillers and adipose tissue. As yet, no incidence rate has been identified. However, a few studies summarized the current strategies for prevention, diagnosis, and management of this complication. Park et al in 2012 reported a consecutive series of 12 patients who suffered ophthalmic, central retinal, and branch retinal vascular occlusions following cosmetic filler injections: 7 patients following adipose tissue injections, 4 following hyaluronic acid, and 1 following collagen. Lazzeri et al published in 2012 a systematic review of 32 cases of blindness following cosmetic filler injections: 15 patients following adipose tissue injections and 17 patients following injections of hyaluronic acid, calcium hydroxyapatite, corticosteroids, silicone oil, paraffin, polymethylmethacrylate, and bovine collagen. Ozturk et al in 2013 published a review of 61 cases of facial vascular occlusion following cosmetic filler injections other than adipose tissue. They reported that 12 patients were complicated by blindness following injections with hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, collagen, and dermal matrix. More recently in 2014, Park et al conducted a national survey of the members of the Korean Retina Society who reported a total of 44 cases of blindness following cosmetic filler injections: 22 patients following adipose tissue injections, 13 following hyaluronic acid, 4 following collagen, 2 following poly-L-lactic acid, 1 following calcium hydroxyl apatite, and 2 cases of unknown injections.
