Abstract

Purpose
To report a case of excessive axial length elongation following vitrectomy for rhegmatogenous retinal detachment.
Case summary
A 21-year-old male patient presented to our hospital with visual impairment. The patient had previously undergone computed tomography in our emergency room for a facial contusion 3 years prior to his current visit. Axial lengths of 27.23 mm in the right eye and 27.62 mm in the left eye were recorded at that time. The patient had no previous ocular history. Fundus examination revealed extensive retinal detachment with macular involvement and hypotony retinopathy in the left eye. Retinal detachment surgery was subsequently performed on the left eye. Following the surgery, intraocular pressure in the left eye increased and intraocular pressure-lowering medications were administered. At 3 months postoperatively, the patient developed additional retinal detachment in the right eye, prompting retinal detachment surgery. Unlike the contralateral eye, the intraocular pressure remained well-controlled postoperatively. Axial length measurement was performed due to the complaint of left eye protrusion. The axial lengths were 27.76 mm and 31.41 mm in the right and left eyes, respectively. There was a significant increase in the axial length of the left eye but not in that of the right eye compared to 3 years prior.
Conclusions
Gas tamponade, preoperative ocular hypotension, and postoperative ocular hypertension can cause excessive axial length elongation in cases of rhegmatogenous retinal detachment in young patients with high myopia.
