Objective To report the visual outcome in patients with a neovascular membrane
(NVM) associated with idiopathic juxtafoveolar telangiectasis (IJFT).
Methods We performed a retrospective, noncomparative analysis of 26 eyes of
16 patients with an NVM associated with bilateral IJFT (Gass classification
group 2A). Eyes were divided into 2 groups: group WO (n = 11) included eyes
with IJFT without evidence of an NVM on initial examination; eyes in group
W (n = 15) had an NVM at the initial diagnosis of IJFT. In group WO, the initial
visual acuity and the time between the initial examination to the diagnosis
of an NVM were evaluated. Characteristic fundus findings, including the presence
or absence of a chorioretinal anastomosis, intraretinal pigmentary plaques,
and crystalline deposits, as well as the final visual acuity were reviewed
for both groups.
Results The initial visual acuity for eyes in group WO ranged from 20/20 to
20/70 (median, 20/30); in group W, from 20/20 to 4/200 (median, 20/70). The
average time from initial diagnosis of IJFT to the development of an NVM was
73 months (range, 5-142 months). In group WO, chorioretinal anastomosis and
concurrent perivascular retinal pigment epithelial hyperplasia were observed
before the development of an NVM. The final visual acuity for all eyes ranged
from 20/40 to 2/200 (median, 20/200). Eighty-one percent of eyes (21/26) had
a final visual acuity of 20/200 or worse.
Conclusions The stable final visual acuity in patients with an NVM associated with
IJFT is generally poor, with 80% of eyes in this series having a final visual
acuity of l20/200 or worse. In patients with IJFT, the presence of a chorioretinal
anastomosis and retinal pigment epithelial hyperplastic plaques always preceded
the development of an NVM.
