ABSTRACT

PURPOSE: To compare the efficacy and safety of Botox and Neuronox in the management of benign essential blepharospasm (BEB). METHODS: We performed a triple-masked, randomized control study to compare Botox and Neuronox in 48 eyes of 24 patients with BEB. All 24 patients randomly received Botox or Neuronox in the periorbital region in a masked, randomized split-face manner, keeping the injection sites and doses uniform. The toxin preparation, injection, and clinical evaluations were done by three independent observers. Objective outcome measures included improvement in the severity of spasm, grading of the functional visual status, changes in palpebral fissure height, lagophthalmos, superficial punctate keratitis and Schirmer's test at 2 weeks, 6 weeks, and upon conclusion of the effect of the toxin. Subjective outcome measures included duration of the effect and a forced choice stating which half of the face was better. Evaluations were performed through clinical measurements, external digital photography, and high-definition videography. RESULTS: The mean duration of relief from spasms was 3.78 months (standard deviation, 1.58 months; range, 1 to 6 months). The improvement in the objective parameters like severity of spasm and functional visual status was statistically significant at the 2-week and 6-week follow-up visits (p < 0.001). The changes in palpebral fissure height, lagophthalmos, and superficial punctate keratitis were equally observed in both groups. At 2 and 6 weeks, three of 24 (12.5%) and one of 24 (4%) patients, respectively, reported an unequal effect between the two sides of the face, but this difference was not statistically significant. At final follow-up (conclusion of the toxin effect), patients reported equal effect with no preference for either hemiface. No statistically significant differences were found in the comparative analysis between the Neuronox and Botox groups. CONCLUSIONS: Neuronox and Botox are comparable in terms of their safety and efficacy in the management of BEB.

ABSTRACT

The human lacrimal gland is an essential component of the lacrimal functional unit [LFU]. Any perturbation of this unit can lead to the debilitating morbid condition called the dry eye syndrome [DES]. The current line of therapy available for dry eye remains supportive and palliative with the patient being dependent on life long and frequent administration of lubricating eye drops. Even advanced therapies like punctual plugs, cyclosporine B administration, and salivary gland auto-transplantation have led to a limited success. Under these scenarios, the option of cell based therapy needs to be explored to provide better and long term relief to these patients. This review gives an overview of the efforts in lacrimal gland regeneration and examines the past and ongoing research in cell based therapies in animals as well as human lacrimal gland cultures. The authors discuss their first of its kind functionally viable human lacrimal gland in vitro culture system from fresh exenteration specimens. A brief overview of research in near future and the potential implications of lacrimal gland regenerative therapies have been discussed

ABSTRACT

To report the outcomes of endoscopic guided anterograde 3 mm balloon dacryoplasty with silicone intubation in patients with acquired partial nasolacrimal duct obstructions in adults. Retrospective case series, included 21 eyes with partially obstructed nasolacrimal ducts of 12 patients. All the 21 ducts were initially probed and the probe confirmed with an endoscope in the inferior meatus. After confirming the presence of probe in the inferior meatus, a 3 mm balloon was used for dilating the distal and proximal portions of nasolacrimal duct, followed by stenting of ducts with Crawford tubes. Main outcome measures were anatomical patency of the passage and resolution of epiphora. Of the 12 patients, 9 had bilateral and 3 had unilateral acquired partial nasolacrimal duct obstructions. All the patients underwent bicanalicular stenting under endoscopic guidance which were retained for a period of 12 weeks. A minimum follow up of 6 months following stent removal was considered for final analysis. 15 of the 21 ducts [71%] were freely patent on irrigation but 13 of the 21 reported improvement of epiphora. Two nasolacrimal ducts showed similar partial regurgitation and partial patency on syringing as before with no improvement of symptoms. Four nasolacrimal ducts were completely obstructed with complete regurgitation of fluid on syringing with worsening of the epiphora. Two eyes persisted with symptoms of epiphora despite patent nasolacrimal duct with grade 2 dye retention on dye disappearance test. 3 mm balloon dacryoplasty is an alternative and safe way to manage partial nasolacrimal duct obstructions with an anatomical success in 71% and functional success in 62% of the patients. Further studies with a large sample size and longer follow-up are required to ascertain the long term benefits

ABSTRACT

Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. It may be performed through an external skin incision or intranasally with or without endoscopic visualization. This article will discuss the indications, goals, and simple techniques for a successful outcome of an external DCR

ABSTRACT

Orbital solitary fibrous tumor [SFT] is a rare tumor originating from the mesenchyme. Initially described in the pleura and subsequently in other mesenchymal structures, orbit continues to be one of the uncommon extrapleural sites. The diagnosis of orbital SFT cannot be made with certainty on clinical or radiological evaluation and requires histologic studies with immunohistochemical confirmation for which CD 34 is the most specific diagnostic test. We describe clinical presentations, radiological and operative findings, and pathological features of a patient with orbital SFT along with a review of literature
