Visual outcome in patients undergoing minimally invasive vitrectomy surgery in rhegmatogenous retinal detachment

Background Micro-incision vitrectomy surgery otherwise called minimally invasive vitrectomy surgery (MIVS) is undoubtedly one of the most impressive evolutions in the surgical retina field of the past decade. This self-healing suture less procedure is safe and reliable with rapid visual recovery. The present study enlightens the visual outcome following MIVS for rhegmatogenous retinal detachment.

Methods This prospective study was done in 68 patients who underwent MIVS for rhegmatogenous retinal detachment. A detailed ocular examination of the patients undergoing MIVS was done. Outcome of the surgery was assessed in terms of functional and anatomical success after one week, 6 weeks and third month.

Results Of the 68 patients, maximum number of patients was in the age group of 51-60 years. Risk factors were previous cataract surgery in 28%, lattice degeneration in 26%, trauma in 22%, myopia in 18% and no specific risk factors in 6%. Mean preoperative BCVA was log MAR 2.16±0.37 and mean post-operative BCVA was log MAR 1.22±0.35 with p value of <0.001 on paired t test indicating the difference was statistically significant. Functional success was achieved in 58% and anatomical success in 94% patients.

Conclusions Visual outcome following MIVS was good for rhegmatogenous retinal detachment. Secondary glaucoma and development or progression of cataract was found to be the major complication following MIVS.  MIVS is a suture less safe surgery facilitating early visual recovery and associated with minimal complications.
