MAIN Sir, Fibrocellular epiretinal membrane formation and subretinal neovascularisation (SRN) are documented sequelae of traumatic choroidal rupture. We herein report a case that illustrates
the development of these complications at different time points following injury and the successful surgical management of both pathologies. CASE REPORT An 18-year-old male sustained a left
closed-globe contusion injury in a road traffic accident, and developed vitreous haemorrhage. He was referred for vitreoretinal management 3 months later following initial observation at a
local hospital. His visual acuity was 6/12 with marked distortion. Fundoscopy revealed a crescent-shaped choroidal rupture concentric to the optic disc and an epiretinal membrane extending
from the rupture (Figure 1). His vision returned to 6/6 after vitrectomy and surgical peeling of this membrane, despite a faint subretinal haemorrhage. Fluorescein angiography confirmed a
subretinal neovascular membrane extending from the rupture towards the fovea (Figure 2a). Given his good visual acuity, and previous experience of spontaneous neovascular membrane
regression, we elected to observe his progress. After 4 months, his visual acuity was 6/12 and the membrane had extended subfoveally (Figure 2b). Surgical removal of the membrane was
planned, prior to which his visual acuity had deteriorated to 6/24 with clinical evidence of membrane extension and increased subretinal haemorrhage. Following surgical removal via a small
retinotomy nasal to the choroidal rupture, his vision improved and was stable at 6/9 (with no significant distortion) 3 months after surgery, without membrane recurrence. Histological
examination of the subretinal neovascular membrane demonstrated RPE cells on one surface and within a fibrovascular core, and no evidence of photoreceptors or Bruchs membrane components.
COMMENT This patient demonstrates two complications of blunt ocular trauma:1 epiretinal membrane formation and SRN.1,2 The sequential development of these complications has not previously
been reported in the same patient. The case supports previous reports of successful management of subretinal neovascular membranes secondary to blunt ocular trauma by surgical removal.3,4
The clinical behaviour and pathological appearance of the subretinal neovascular membrane in this case suggests that it was a ‘type 2’ membrane5 (ie neovascularisation below neurosensory
retina but internal to viable RPE), increasing the likelihood of a good visual outcome from subretinal surgery. Gass has previously noted that choroidal neovascularisation arising at the
site of an old choroidal rupture is usually type 2.6 Glial proliferation has a central role in epiretinal membrane formation—retinal glial cells can extend through defects in the inner
limiting membrane (ILM), and may also be capable of producing ILM breaks through which they can extend processes onto the ILM surface.7 In the case we have described, the epiretinal membrane
appeared to extend from the choroidal rupture towards the fovea. It is likely that inner retinal disruption and microscopic breaks in the ILM at the time of traumatic choroidal rupture
provided the basis for subsequent glial extension and epiretinal membrane formation. In addition, the fibroglial scar at the site of the choroidal rupture provides an anchor for the
epiretinal membrane, any subsequent membrane contraction enhancing the clinical appearance of the membrane extending from the rupture. Management of epiretinal membranes invariably involves
vitrectomy surgery; however, other treatment options are now available for SRN. Photodynamic therapy (PDT) may limit progression (although not widely available at the time of presentation of
this case) in some age-related macular degeneration SRN; however, the value of PDT in post-trauma SRN is unproven. Likewise, trans-pupillary thermotherapy may offer a benefit in SRN
treatment, but its efficacy requires further investigation. It is uncertain whether any of the alternative novel treatment options for SRN could result in a visual improvement from 6/24 to
6/9, which was achieved by surgical management of the SRN in this case. REFERENCES * Williams DF, Mieler WF, Williams GA . Posterior segment manifestations of ocular trauma. _Retina_ 1990;
