Intraoperative three-dimensional fluorescein angiography-guided pars plana vitrectomy for branch retinal vein occlusion

Purpose. To evaluate the effects of pars plana vitrectomy (PPV) on recurrent macular edema due to branch retinal vein occlusion (BRVO) after intravitreal injections of bevacizumab (IVB).Methods. This retrospective study included 22 eyes of 22 patients who underwent single or multiple IVB injections for macular edema due to BRVO and showed a recurrence of macular edema. All patients then underwent PPV and were followed up for more than 6 months after the surgery with examinations of best corrected visual acuity (BCVA) and optical coherence tomography (OCT). OCT parameters were central macular thickness (CMT) and average retinal thickness in a 1-mm-diameter circular region at the fovea (MRT).Results. Mean BCVA, CRT, and MRT were significantly improved from the baseline after PPV. Greater improvement of BCVA, CRT, and MRT was obtained after 1 month of IVB than after 6 months of PPV. No eyes showed worsening of macular edema after the surgery.Conclusion. PPV improved BCVA and recurrent macular edema due to BRVO, but PPV that was less effective than IVB had been in the same patients. PPV may be one of the treatment options for recurrent macular edema due to BRVO after IVB.

Macular tears rarely occur without trauma. Here, we describe a patient with vitreous haemorrhage, which was caused by an unusual giant macular tear secondary to existing branch retinal vein occlusion. A 60-year-old woman presented with vision loss in the right eye because of vitreous haemorrhage. She had a history of branch retinal vein occlusion and had been treated with retinal photocoagulation 3 years prior. As treatment for vitreous haemorrhage, the patient underwent 23-gauge pars plana vitrectomy combined with silicone oil tamponade. During the operation, a large jagged tear was observed in the macula. We presumed that stretching of the fibrous proliferating membrane secondary to branch retinal vein occlusion was responsible for the macular tear and vitreous haemorrhage. Eventually, the results of pars plana vitrectomy led to anatomical closure of the macular tear and partial restoration of visual acuity.

Even though the diagnosis depends on clinical examination, in cases with branch retinal vein occlusion (BRVO), fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) provide unique data for follow-up, management and prognosis. In FFA, delay of laminar flow phase in the involved branch, hyperfluorescence due to leakage from the vessel wall in the late phases, hypofluorescence due to the blockage by hemorrhage, and soft exudates, and hyperfluorescence due to macular edema can be detected. In OCT, macular thickening, cystic spaces, serous retinal detachment, hyperreflective dots, disorganization of the outer retinal layers – particularly the photoreceptor inner and outer segments line and the external limiting membrane – can be seen. OCTA reveals non-perfusion, particularly in the deep capillary plexus.
