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.

IVB injection as monotherapy seems to be a very effective treatment modality for ROP. Based on timely intervention, IVB as a single treatment modality can salvage almost all ROP cases before stage 4.

As trypan blue is a potentially carcinogenic vital dye and its possible long-term side effects are unknown, the lowest effective concentration should be used. A concentration lower than 0.1% was effective in staining the anterior capsule even under dispersive viscoelastic material.

The incidence of ROP observed in this study was higher than that in developed countries and relatively more mature infants were affected. Criteria including gestational age of less than 34 weeks or birth weight of less than 2,000 g would have identified all infants who were at risk.
