Purpose: To assess the outcome of scleral buckling surgery using a non-contact wide-angle viewing system for fundus visualization in patients with rhegmatogenous retinal detachment without proliferative vitreoretinopathy. Patients and Methods: Sixteen eyes of 16 patients underwent scleral buckling using a non-contact wide-angle viewing system combined with a 25-gauge illumination fibre inserted into the sclera at the pars plana. Results: The mean age of the patients was 53.6 ± 13.7 years and the mean follow-up time was 13.4 ± 2.8 months. Retinal reattachment was achieved in 13 of the 16 eyes (81%). Three eyes underwent vitrectomy with silicone oil injection because of development of proliferative vitreoretinopathy in 2 eyes and scleral perforation due to excessive indentation during cryoretinopexy in 1 eye. Two eyes developed limited subretinal haemorrhage during subretinal fluid drainage. Conclusion: Simultaneous use of a non-contact wide-angle viewing system combined with a 25-gauge light fibre illumination for fundus visualization brings the advantages of microsurgery and indirect ophthalmoscopy into scleral buckling surgery.
Silicone oil has an antimicrobial activity against S. aureus, S. epidermidis, P. aeruginosa, C. albicans, and Aspergillus spp., which are common endophthalmitis-causing agents.
ILM peeling at the macula during vitreous surgery with silicone oil for the treatment of complicated retinal detachment may prevent epimacular membrane formation without negatively affecting distant visual acuity.
The Hansatome microkeratome does not always produce a corneal flap of the intended thickness. Factors other than keratometry and pachymetry must affect flap thickness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
