Abstract

PURPOSE
To analyse the outcomes of pneumatic displacement of sub macular haemorrhage (SMH)
METHODS
Retrospective study of 20 eyes of 20 consecutive patients presenting with SMH. Treated with intravitreal expansile gas (0.5ccSF6 / 0.3cc C3F8) +/- anti-VEGF injection. Outcome measures were change in BCVA, SMH displacement, complications and need for additional treatment.
RESULTS
Mean duration of symptoms 13days (1-90). Etiology: PCV/CNVM (n=14), trauma (n=3), Valsalva retinopathy(n=2), RAM (n=1). Mean pretreatment SMH size was 3.75 DD (1-8DD). Anti-VEGF injections used in 16 eyes [mean 3.6]. BCVA improved in 13 and worsened in 5 cases at a mean final follow up of 8.5 months.. SMH disappeared completely (n=12), displaced extrafoveally in 2. Complications: VH (n=5), Macular hole (n=1), RRD (n=1). Vitrectomy was needed in 3 eyes
CONCLUSIONS
Intravitreal expansile gas injection can be an effective and convenient procedure for pneumatic displacement of SMH secondary to various etiologies
