To use a 25-gauge chandelier for retinal visualization during scleral buckling surgery for rhegmatogenous retinal detachment.
Department of Ophthalmology, Peking University Third Hospital, Beijing, 100191 China
A 25-gauge chandelier was inserted through the pars plana for intraocular illumination, and a corneal contact lens was used for intraocular visualization under a surgical microscope. With this method, the retinal hole could be identified, and 46 patients (age 12-62) with rhegmatogenous retinal detachment were performed with trans-scleral cryotherapy and episcleral buckle. After surgery 1，3and 7days, the intraocular pressure was measured by non-contact tonomator. After surgery 3 months, ultrasound biomicroscopy was taken for the eyes.
In the surgical procedure, there was not lens or retinal damage duo to the chandelier. After surgery, there was not inflammation or hemorrhage to be observed in the vitreous. There was not leakage to be found from pars plana incision after surgery. The intraocular pressures were respectively 15.55±3.17mmHg, 15.75±2.99mmHg and 16.19±2.61mmHg at 1, 3 and 7 days after surgery. In one case, retinal detachment was recurrent due to proliferative vitreoretinopathy. There is not complication of incision of pars plana to be found.
Comparing with the standard indirect ophthalmoscopy, surgical microscope with chandelier illumination could provide positive and variable magnified image for retinal visualization during the surgery. The learning curve for this technique may be shorter than indirect ophthalmoscopy.
