A prospective study of the role of intralesional bleomycin in orbital lymphangioma.

PURPOSE: To evaluate the efficacy of intralesional bleomycin injection in the management of lymphangiomas of the orbit. METHODS: This prospective noncomparative interventional case study included 13 patients with orbital lymphangiomas. Reconstituted bleomycin 1-5 ml (0.5 IU/kg body weight; maximum, 15 IU/ml) was injected with 2% lignocaine in the lesion as seen on imaging or, in deeper lesions, under ultrasound guidance. Repeat injections were administered when required after every 4 weeks. The decision to retreat was based on clinical and radiological evidence of response. RESULTS: Patients were treated with 1-6 injections of bleomycin 0.5 IU/kg body weight. Dramatic response was achieved in all cases. During the mean follow-up period of 19.69 months (range, 7-26 months) none of the patients experienced recurrence or significant complication. CONCLUSIONS: In this patient cohort lymphangiomas of the orbit showed favorable and promising results with intralesional injections of bleomycin. This treatment should be considered as a first-line therapy for lymphangiomas of the orbit.

The diagnostic yield of neuroimaging in sixth nerve palsy--Sankara Nethralaya Abducens Palsy Study (SNAPS): Report 1.

AIMS: The aim was to assess the etiology of sixth nerve palsy and on the basis of our data, to formulate a diagnostic algorithm for the management in sixth nerve palsy. DESIGN: Retrospective chart review. RESULTS: Of the 104 neurologically isolated cases, 9 cases were attributable to trauma, and 95 (86.36%) cases were classified as nontraumatic, neurologically isolated cases. Of the 95 nontraumatic, isolated cases of sixth nerve palsy, 52 cases were associated with vasculopathic risk factors, namely diabetes and hypertension and were classified as vasculopathic sixth nerve palsy (54.7%), and those with a history of sixth nerve palsy from birth (6 cases) were classified as congenital sixth nerve palsy (6.3%). Of the rest, neuroimaging alone yielded a cause in 18 of the 37 cases (48.64%). Of the other 19 cases where neuroimaging did not yield a cause, 6 cases were attributed to preceding history of infection (3 upper respiratory tract infection and 3 viral illnesses), 2 cases of sixth nerve palsy were found to be a false localizing sign in idiopathic intracranial hypertension and in 11 cases, the cause was undetermined. In these idiopathic cases of isolated sixth nerve palsy, neuroimaging yielded no positive findings. CONCLUSIONS: In the absence of risk factors, a suggestive history, or positive laboratory and clinical findings, neuroimaging can serve as a useful diagnostic tool in identifying the exact cause of sixth nerve palsy. Furthermore, we recommend an algorithm to assess the need for neuroimaging in sixth nerve palsy.

Cataract surgery in a case of carotid cavernous fistula.

A carotid-cavernous fistula (CCF) is an abnormal communication between the cavernous sinus and the carotid arterial system. The ocular manifestations include conjunctival chemosis, proptosis, globe displacement, raised intraocular pressure and optic neuropathy. Although management of CCF in these patients is necessary, the ophthalmologist may also have to treat other ocular morbidities such as cataract. Cataract surgery in patients with CCF may be associated with many possible complications, including suprachoroidal hemorrhage. We describe cataract extraction surgery in 60-year-old female with bilateral spontaneous low-flow CCF. She underwent phacoemulsification via a clear corneal route under topical anesthesia and had an uneventful postoperative phase and recovered successfully. Given the various possible ocular changes in CCF, one must proceed with an intraocular surgery with caution. In this communication, we wish to describe the surgical precautions and the possible pitfalls in cataract surgery in patients with CCF.
