Purpose: To describe the results of a conservative and reversible technique for the treatment of progressive myopathic blepharoptosis in cases when surgery is not indicated, using octyl-2-cyanoacrylate liquid bandage. Methods: Ten consecutive patients with progressive myopathic blepharoptosis were studied. Octyl-2-cyanoacrylate liquid bandage was applied to the upper eyelid to create a deeper eyelid crease. Margin reflex distance, photographs, and visual fields were obtained prior to and after treatment. Results: All patients described a better appearance after application of the product, and none had an allergic response. All cases had an increase in the margin reflex distance and improvement in visual fields. Conclusion: Octyl-2-cyanoacrylate liquid bandage is an alternative method that is simple, safe, and effective in the management of severe blepharoptosis. Moreover, it can be used in patients without systemic conditions or those who are unwilling to undergo a surgical procedure.

Midori Hentona Osaki; Tammy H. Osaki; Teissy Osaki

PURPOSE In Asian patients, lateral hooding in the aging upper eyelid is prominent and frequently seen. Removal of the redundant skin of this region during classic blepharoplasty tends to produce a resultant prolonged scar. Furthermore, as the height of the eyelid skin excision increases, suturing of the thick upper skin to the thin pretarsal skin can result in upper lid fullness. This study documents the combination of infrabrow skin excision and upper blepharoplasty to address lateral hooding in select patients of Asian ancestry. METHODS This study is a retrospective chart review of patients who underwent infrabrow skin excision associated with upper blepharoplasty. The inclusion criteria were moderate and severe upper eyelid dermatochalasis in patients with high eyebrows and lateral hooding; residual lateral hooding following previous blepharoplasty. RESULTS Thirty-two eyelids of 16 female patients of Japanese ancestry underwent infrabrow skin excision associated with upper blepharoplasty. The mean age of patients was 68.87 ± 7.88 years (57-82 years). Mean follow up was 37.25 ± 18.96 months (9-72 months). Patients were evaluated at 1, 3, 6, and 9 months at least. The Strasser system for evaluation of surgical results was applied at 3 months. All patients had scores indicating good results and were satisfied with the cosmetic outcome and improvement of visual field after surgery. No complications related to wound dehiscence, lagophthalmos, hypertrophic scars, or sensory changes were observed. CONCLUSION The combination of infrabrow skin excision and upper blepharoplasty was effective to address moderate and severe dermatochalasis with lateral hooding in select patients of Japanese ancestry.

Background/aims In patients with hemifacial spasm (HFS), treatment relieves eyelid spasms on the affected side, thus changes in corneal topography and eyelid morphometry may be observed after treatment. We aimed to evaluate these parameters during a 4-month period in patients with HFS treated with botulinum toxin A (BTX-A). Methods This prospective study evaluated eyelid morphometric and corneal topographic changes in patients with HFS before onabotulinum toxin A application, and after 15 days and 2, 3 and 4 months. Results 24 patients were treated with BTX-A. On the normal side, the mean palpebral fissure height (PF), interpalpebral surface area (ISA), steep K and astigmatism values were 8.7±1.98 mm, 122.09±39.37 mm2, 44.99±1.45 D and 0.9±0.64 D, respectively, before treatment. A statistically significant difference was not observed in these parameters after treatment (p>0.05). On the affected side, the mean PF, ISA, steep K and astigmatism were 5.5±1.77 mm, 67.68±28.49 mm2, 46.91±3.57 D and 2.63±2.46 D, respectively, before treatment. We observed a statistically significant (p<0.05) increase in the mean PF and ISA on the affected side 15 days (8.36±1.91 mm and 115.92±34.44 mm2, respectively), 2 months (8.18±1.80 mm and 112.22±33.57 mm2, respectively) and 3 months (7.27±1.65 mm and 95.48±27.80 mm2, respectively) after treatment. A statistically significant decrease in steep K and astigmatism was observed at 2 months (45.14±1.20 D and 1.01±0.58 D, respectively) and 3 months (45.64±1.77 D and 1.36±1.31 D, respectively) after treatment. Conclusions The results suggest that treatment with BTX-A in patients with HFS leads to eyelid and corneal changes on the affected eye that are significant during the known period of action of the toxin. Thus, caution should be taken when performing ophthalmological examination in patients with HFS, since it may vary according to BTX-A period of action.

BACKGROUND Botulinum toxin type A (BTX-A; Botox) is supplied as individual freeze-dried preparations that should be administered within 24 hours after reconstitution. To avoid wasting this expensive drug, some physicians have resorted to storing vials of reconstituted BTX-A beyond the recommended duration. However, there is insufficient evidence to indicate that the sterility of previously reconstituted BTX-A is maintained during storage. OBJECTIVES The authors sought to determine whether bacterial and/or fungal proliferation occurred in vials of reconstituted BTX-A and subsequent storage of the remaining solution under refrigeration for 4 weeks. METHODS A portion of the contents of 88 consecutive 100-U vials of BTX-A was administered aseptically to 108 patients for essential blepharospasm, hemifacial spasm, or facial rejuvenation. The vials were then stored for 4 weeks in a refrigerator, after which the contents were transferred to various media (blood agar, chocolate agar, Sabouraud agar, brain-heart infusion medium, and thioglycolate broth) and assessed for bacterial and/or fungal growth by standard methods. RESULTS None of the BTX-A vials contained detectable bacterial or fungal contamination after 4 weeks of storage. CONCLUSIONS Storing vials of reconstituted BTX-A for 4 weeks after administration to patients was not associated with detectable growth of bacteria or fungi.

PURPOSE To evaluate the use of octyl-2-cyanoacrylate liquid bandage (Band-Aid liquid, Ethicon, Johnson & Johnson, New Jersey, USA) as a temporary treatment in patients awaiting surgical repair for involutional entropion. METHODS Thirteen patients (15 eyelids) with involutional entropion were evaluated while they waited for surgical intervention. The lids were repositioned by the application of octyl-2-cyanoacrylate liquid bandage in the malar fold. Patients were followed-up at days 1, 7 and 15. Assessment and duration of correction were recorded. RESULTS All the patients presented successful correction at day 1, with significant improvements in signs and symptoms. The mean duration of action of the octyl2-cyanoacrylate liquid bandage was three days. No ocular or dermatological reactions were noted. CONCLUSION Octyl-2-cyanoacrylate liquid bandage showed to be a simple, safe and effective option to temporarily treat involutional entropion, while patients waited for surgical intervention.

Purpose To evaluate the effect of eyelid spasm treatment with botulinum toxin‐A (BTX‐A) on corneal curvature assessed with Scheimpflug (Pentacam) and Placido (Atlas) systems. Setting Federal University of São Paulo, São Paulo, Brazil. Design Prospective interventional case series. Methods Patients with hemifacial spasm were evaluated. Steep keratometry (K) and corneal astigmatism (magnitudes and treatment‐induced astigmatism) obtained with the Placido and Scheimpflug systems were evaluated before BTX‐A application and after 15 days and 2, 3, and 4 months. Results The study evaluated 48 eyes (24 affected and 24 normal contralateral eyes) of 24 patients. The mean steep K and astigmatism values obtained with the Placido system on the affected side before treatment were 46.91 diopters (D) ± 3.57 (SD) and 2.63 ± 2.46 D, respectively. A significant decrease in steep K (45.14 ± 1.20 D) and astigmatism (1.01 ± 0.58 D) was observed 2 months (P = .003 and P = .0004, respectively) and 3 months (45.64 ± 1.77 D and 1.36 ± 1.31 D, respectively) (P = .03 and P = .01, respectively) after treatment. The Scheimpflug system did not show significant changes in steep K measurements during the 4‐month period. The mean astigmatism in the affected eye before treatment was 1.27 ± 0.88 D. A significant reduction was observed at 15 days (1.16 ± 1.16 D) and at 4 months (0.91 ± 0.59 D) (P = .02 and P = .03, respectively). Conclusion The Placido system was more sensitive in detecting a temporary reduction in corneal curvature after eyelid‐spasm treatment.

Ultrasound imaging is not traditionally employed to evaluate eyelid lesions. Nevertheless, this technology permits the delineation of static and dynamic changes and could be useful in evaluating eyelid masses by providing additional information to clinicians for optimal surgical planning, especially in facilities where a computed tomography (CT) scan is not readily available. A 63-year-old woman presented in April 2014 with a painless mass in the right upper lid (RUL) associated with ptosis (Figure 1A) that had gradually developed during the previous 10 months. Retinopexy associated with vitrectomy with intraocular silicone oil filling was performed 15 months before to treat a retinal detachment in the right eye. Silicone oil was removed 8 months later. For the past 4 months, patient was under investigation for a breast nodule. Figure 1. (A) This 63-year-old woman presented with a painless mass in the right upper eyelid associated with upper lid ptosis that had gradually developed for 10 months. (B) Final aspect 1 year after excision of the mass and reinsertion of the levator aponeurosis to the tarsus. Marginal reflex distance (MRD-1) was −1 on the right and +3 on the left side. Levator function was 13 and 15 mm. Best corrected visual acuity was counting fingers 2 …

Keratoconus progression is not inhibited by reducing eyelid muscular force with botulinum toxin A treatment: a randomized trial

Teissy Osaki; Midori Hentona Osaki; Flavio E. Hirai; Mauro Campos

Purpose: To evaluate whether reducing eyelid muscular force through the administration of botulinum toxin type A (BTX-A) to the orbicularis oculi muscles of patients with keratoconus affected corneal parameters indicative of disease progression. Methods: In this prospective parallel randomized clinical trial, 40 eyes of 40 patients with keratoconus were randomized into equally sized control and BTX-A groups. Patients in the BTX-A group received subcutaneous BTX-A injections into the orbicularis muscle. The control group received no intervention. Palpebral fissure height, best spectacle-corrected visual acuity (BSCVA), and corneal topographic parameters were evaluated at baseline and at 3-, 6-, 12-, and 18-month follow-ups. Results: The mean ± standard deviation vertical palpebral fissure heights were 9.74 ± 1.87 mm and 9.45 ± 1.47 mm at baseline in the control and BTX-A groups, respectively, and 10.0 ± 1.49 mm and 9.62 ± 1.73 mm at 18 months, with no significant difference between the groups (p=0.337). BSCVA values were 0.63 ± 0.56 and 0.60 ± 0.27 at baseline in the control and BTX-A groups (p=0.643), and 0.52 ± 0.59 and 0.45 ± 0.26 at 18 months, again with no significant difference between the groups (p=0.452). In addition, there were no statistical differences between the groups at 18 months for the three keratometry topographic parameters: flattest (K1), steepest (K2), and mean (Km) keratometry (p=0.562). Conclusion: BTX-A inhibition of eyelid force generation did not result in detectable changes in corneal parameters in keratoconic patients during 18 months of follow-up.

Teissy Osaki; Midori Hentona Osaki; Tammy H. Osaki; Flavio E. Hirai; Mauro Campos

Purpose: To investigate possible temporary differences in corneal topographic parameters between affected and normal eyes in patients with hemifacial spasm (HFS) treated with botulinum toxin-A (BTX-A), over the course of 1 treatment cycle. Methods: This prospective study evaluated corneal topographic differences between affected and normal contralateral eyes during a 4-month period in patients with HFS treated with BTX-A (the duration of action of BTX-A for HFS ranges from 2 to 4 months). Corneal topographic analysis was performed using a conventional topographer (Atlas; Carl Zeiss Meditec, Dublin, CA). Steep K and astigmatism measurements were evaluated before BTX-A application and after 15 days and 2, 3, and 4 months. Results: Twenty-four patients (16 women and 8 men) were evaluated. Steep K [46.9 ± 3.6 diopters (D)] and astigmatism values (2.6 ± 2.5 D) were significantly higher in affected eyes of HFS patients than in nonaffected eyes (45.0 ± 1.4 D and 0.9 ± 0.6 D) before treatment (P = 0.001 for steep K and P = 0.0003 for astigmatism). Astigmatism values also showed significant differences between the affected eye (1.4 ± 0.8 D) and nonaffected eye (0.9 ± 0.6 D) at 4 months (P = 0.006), whereas steep K showed significant differences between both eyes at 15 days (affected eye: 45.6 ± 1.5 D, nonaffected eye: 45.0 ± 1.4 D, P = 0.008), 3 months (affected eye: 45.6 ± 1.8 D, nonaffected eye: 45.1 ± 1.3 D, P = 0.03) and 4 months (affected eye: 45.8 ± 1.2 D, nonaffected eye: 45.1 ± 1.4 D, P = 0.003) after treatment. Conclusions: The differences in steep K, and especially in astigmatism values, between eyes tended to reduce during the period of action of BTX-A. At 4 months, when the BTX-A effect is considered to be over or very reduced, a significant difference between eyes for both parameters was noted again.
