Dear Editor,
We read with interest the paper “Comparison of retinal detachment surgery outcome among patients undergoing pars plana vitrectomy with and without relaxing retinotomy” written by Frenkel T et al. [1]. They reported functional and anatomical outcomes in patients who underwent pars plana vitrectomy for complicated retinal detachment due to various etiologies. They compared the outcomes between pars plana vitrectomy performed without retinotomy and performed with retinotomy. Interestingly, their findings showed that retinotomy itself does not increase the rate of treatment failure or worse outcomes. This may really help clinicians with decision-making when faced with complicated retinal detachments. However, there is no description of the term “complicated retinal detachment”, which is mentioned as a limitation of the current study. We think that at least a general description would really improve the understandings of readers. In addition to this, they did not specify the sclerotomy size (20-, 23- or 25-gauge). This really matters, since the rate of complications such as the rate of postoperative hypotony varies among different sclerotomy sizes, and eventually may affect the final outcome [2, 3]. There were four cases in the vitrectomy plus retinotomy group which developed macular hole after surgery, and were followed up conservatively. We would be keen to know if the authors can share their ideas on the possible mechanisms for macular hole development, and relations with retinotomy. Secondly, what were their objective criteria for not proceeding with macular hole surgery?
