The role of the volume of endolaser coagulation in the appearance of perisilicone proliferation in retinal detachment surgery

Abstract

Background. Endolaser coagulation (ELС) is an integral part of endovitreal retinal detachment (RD) surgery. The study of the role of ELC volume (total laser energy and the amount of applied coagulates) in the formation of perisilicone oil proliferation (POP) after RD surgery of various origins is necessary to prevent postoperative complications.

The purpose of this study was to study the role of the ELC volume in the formation of POP in RD surgery of various genesis.

Materials and methods. The study was conducted in the private clinic “SIHAT KO’Z” from 2019 to 2021. 88 (88 eyes) patients with retinal detachment of different genesis were examined. The age range varied from 21 to 67 years, the average age was 47.4 ± 3.1 years. 61 (69%) patients had rhegmatogenous RD, 27 (31%) tractional RD. The macular area was involved in RD in 64 (73%) cases, and was intact in 24 (27%) cases.

Results. In 11 patients PP formed the day after surgery, in 4 (4.5%) exudate and fibrin were formed in the anterior chamber, in 4 (4.5%) re‑injection of silicone oil was required due to incomplete retinal adhesion. In 2 (2.3%) cases iridocorneal adhesions were formed. The study showed that the occurrence of the above complications was directly related to the intensive effect of ELC during surgery for retinal detachment.

Conclusion. Thus, increased coagulation and energy volume in ELC during surgical treatment of retinal detachment is important in the occurrence of PP. The analysis revealed a clear relationship between the development of a proliferative membrane and the volume of ELC. Since PP is a factor that reduces the effectiveness of surgical treatment of retinal detachment, the recommendation is to reduce the volume of ELC to the minimum necessary.
