1/6. Congenital sensory neuropathy. Ophthalmological implications.The authors examined a patient presenting with congenital sensory neuropathy with selective loss of small myelinated nerve fibres. The appearance of (bilaterial) keratitis or corneal ulceration in early childhood is strongly suggestive of congenital corneal anaesthesia. Concomitant symptoms such as anisocoria, abnormal pupillary reaction, diminished tear production and disturbed sensibility to pain and temperature point to a generalized disease: one of the hereditary sensory and autonomic neuropathies. In order to establish a definite diagnosis, elaborate neurological examination, including ultrastructural study of a muscle-nerve biopsy, is required. Tarsorrhaphy, therapeutic flushfitting PMMA scleral lenses and hydrophilic HEMA contact lenses are advocated, in order to protect the cornea. The results with high-water-content hydrophilic contact lenses are promising, those of keratoplasty limited.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/6. Orbital swelling as a sign of live Dirophilaria repens in subconjunctival tissue.This report presents a case of live dirophilaria found in the subconjunctival space in a woman, in whom the main symptoms were swelling of the orbital tissue. After subconjunctival anaesthesia the dirophilaria were removed surgically. A histopathological examination revealed an adult, non-gravid female dirofilaria repens s. acutiuscula. To the authors' knowledge this is the first case of subconjunctival live dirophilaria reported in a human.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
3/6. Conjunctival rhinosporidiosis.Conjunctival rhinosporidiosis is usually a surprise diagnosis in histological section of an excised conjunctival mass. The condition is rarely encountered outside the endemic coastal areas of South india. Accurate diagnosis of this rare condition is infrequent in clinical practice; tumour, neoplasm, papilloma being the common misdiagnoses. Herein, a report of a case of an 18-year-old otherwise healthy male who attended outpatient department of Regional Institute of ophthalmology, Medical College, Kolkata with a red fleshy papillomatous growth about 7 mm x 4 mm in size, in the palpebral conjunctiva just behind the intermarginal strip of his right upper lid. His routine blood examination was within normal limits. The growth was excised under local anaesthesia and histopathological examination revealed rhinosporidiosis. There was no recurrence of the growth within one month of follow-up.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
4/6. Conjunctival inclusion cyst following sub-Tenon's local anaesthetic injection.Sub-Tenon's local anaesthesia has become a popular technique of infiltrative anaesthesia for small incision cataract surgery. We report the development of an inclusion cyst of the conjunctiva following this technique. The aetiology of this complication and how it can be avoided are discussed.- - - - - - - - - - ranking = 2keywords = anaesthesia (Clic here for more details about this article) |
5/6. First report of ophthalmomyaisis externa in pakistan.Two individuals presented to the Aga Khan University Opthalmology service with foreign-body sensation, pain and redness in one of their eyes. Slit-lamp biomicroscopy revealed tiny larvae crawling around the conjunctival sac. They were mechanically removed under topical anaesthesia and preserved for light microscopy and photography. Comprehensive liaison was established with the Australian Centre for International agriculture research for identification of these larvae. Their morphology characterized them as members of fruit-fly, Oestridae family. At least one of them was positively identified as first instar larva of Oestrus ovis. This report describes the first instance of such infections in Southern pakistan, as concluded after a medline search.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
6/6. Sub-Tenon's anaesthesia: an efficient and safe technique.AIM: To evaluate sub-Tenon's anaesthesia as an alternative to peribulbar anaesthesia. methods: 109 consecutive patients listed for various eye operations (including cataract, trabeculectomy, and vitrectomy) under peribulbar anaesthesia were operated on under sub-Tenon's anaesthesia instead. After topical anaesthesia a buttonhole was fashioned through the conjunctiva and Tenon's capsule 10 mm posterior to the limbus. 1.5 ml of lignocaine 2% was then delivered to the posterior sub-Tenon's space using a blunt cannula. The surgical procedure was performed immediately after the completion of the anaesthetic procedure. Chemosis, conjunctival haemorrhage, degree of akinesia, and pain scoring were analysed. RESULTS: There were no anaesthesia related complications. The administration of the block was painless for 99.1% of the patients. In all, 97.3% reported no pain during surgery. There was no akinesia when assessed just after the completion of the block and akinesia was limited when assessed after surgery. Chemosis and conjunctival haemorrhage were frequent but caused no intraoperative problems. CONCLUSION: Sub-Tenon's anaesthesia is an efficient and safe anaesthetic technique. It is a good alternative to peribulbar anaesthesia.- - - - - - - - - - ranking = 12keywords = anaesthesia (Clic here for more details about this article) |
