# A Case of Total Retinal Detachment With Multiple Retinal Cysts Showing a Favorable Postoperative Course

## TL;DR

A 29-year-old man with severe retinal detachment and multiple retinal cysts showed improved vision after surgery without removing the cysts.

## Contribution

This case suggests that retinal cysts from prolonged detachment may resolve post-surgery without direct intervention.

## Key findings

- The patient's vision improved to 20/22 after retinal detachment surgery.
- Retinal cysts resolved postoperatively without requiring surgical removal.
- Prolonged retinal detachment may lead to the formation of retinal cysts.

## Abstract

A 29-year-old man was aware of vision loss in his left eye that had been present for about two years. At the time of his visit to our clinic, his best-corrected visual acuity (BCVA) was 20/16 in the right eye and 20/200 in the left eye. There were no abnormal findings in the anterior or intermediate translucent areas of either eye. The fundus examination revealed a retinal dialysis in the inferior nasal retina of the left eye, followed by multiple retinal cysts on the pole side, and total retinal detachment. The fundus of the right eye showed no abnormal findings of note. A diagnosis of rhegmatogenous retinal detachment (RRD) of the left eye was made, and cataract surgery, encircling, and vitrectomy were performed. Intraoperatively, retinal cysts that did not seem to affect closure of the tear were left untreated. Postoperatively, the fluid in the retinal cyst disappeared and retinal restoration was achieved. The BCVA recovered to 20/22. In this case, the retinal cyst may have formed as a result of prolonged retinal detachment. The results of this case suggest that surgical treatment of the retinal cyst and complete removal of the intraretinal fluid may not be necessary.
