abstract = {Background:To characterize the effects of intravitreal
injections of iodoacetic acid (IAA) in comparison to its
systemic application as a measure to induce unilateral
photoreceptor degeneration.Methods:Seven-week-old C57BL/6 J
mice received either intravitreal injections of IAA or
systemic treatment (intraperitoneal vs intravenous) and were
observed in the following 5 weeks using ERG, OCT, and
histology.Results:Systemic treatment with IAA induced high
toxic effects and a high mortality in contrast to the
intravitreal injection. Intraperitoneal application had no
effect on the retina. Intravenous application of 2 × 30
mg/kg BW IAA (time between injections 3.5 h) resulted in an
extinction of the ERG and a thinning of the retina, in
particular of the outer nuclear layer (ONL) indicating
photoreceptor degeneration. Animals receiving intravitreal
injections developed cataracts already at low concentrations
(up to 100 $\%$ at 0.25 mg/kg BW). Higher intravitreal IAA
doses led to extinguished ERGs. In histology, a thinning of
the entire retina was observed that was most prominent in
the inner part of the retina.Conclusions:In contrast to
intraperitoneal administration, intravenous application of
IAA led to a selective photoreceptor degeneration. After
intravitreal injection, dense cataracts were already
observed at concentrations lower than those needed to induce
changes in the ERG. ERG results must be interpreted
carefully. A thinning of all retinal layers rather than a
specific outer retinal degeneration was observed upon
intravitreal injection. IAA is not a useful model to induce
outer retinal degeneration in mice.},
