Purpose: To investigate the outcomes of scleral buckling surgery performed under a slit-lamp illumination system(Visulux) with a contact wide-angle viewing lens (Mini Quad) in patients with rhegmatogenous retinal detachment(RRD) and to compare these outcomes with those of surgery performed under an indirect ophthalmoscope. Methods: By retrospective review of electronic medical records, patients with RRD who had undergone scleralbuckling surgery were identified. Scleral buckling surgeries were performed with two illumination instruments,a slit-lamp (SL group) and an indirect ophthalmoscope (IO group). Subretinal fluid drainage, cryopexy, andintravitreal gas injection were performed optionally. At 6 months after surgery, anatomical and functional outcomeswere evaluated and compared between the two groups. Operation time was also compared betweenthe two groups. Results: Of the 45 total patients (45 eyes), 28 were included in the SL group, and 17 were included in the IOgroup. In the SL and IO groups, the primary anatomical success rate was 89.3% and 88.2%, respectively (p =0.92). The logarithm of the minimal angle of resolution change, which reflects improvement in best-correctedvisual acuity after surgery, was -0.19 ± 0.38 in the SL group and -0.21 ± 0.63 in the IO group; this differencewas not statistically significant (p = 0.91). The mean operation time was significantly shorter in the SL group(78.9 ± 11.8 minutes) than in the IO group (100.0 ± 13.9 minutes, p < 0.001), especially for patients who underwentadditional procedures such as subretinal fluid drainage and cryopexy (81.4 ± 12.9 and 103.5 ± 12.3 minutes,respectively, p < 0.001). Conclusions: Scleral buckling surgery performed under a slit-lamp illumination system yielded a similar anatomicalsuccess rate and similar functional improvement in RRD compared with surgery performed under anindirect ophthalmoscope. The slit-lamp system could save time, especially in bullous RRD, which requires additionalsubretinal fluid drainage.
