"Pacman" invasion of the retina: Two cases of ophthalmomyiasis interna posterior.

ABSTRACT:

Purpose

To discuss two striking cases of ophthalmomyiasis interna posterior, in which the larval stage of a botfly is found in the posterior segment.

Observations

In the first case, the subretinal maggot is alive and found to be migrating under the retina. The maggot was lasered in the office and killed. In the second case, a dead maggot was discovered in the subretinal space in a child, after it had caused significant subretinal scarring and permanent vision loss.

Conclusions and importance

Ophthalmomyiasis is a rare condition that can often be unrecognized and result in permanent vision loss. Early diagnosis and photocoagulation of the larva (if alive) can halt progression of vision loss in these cases.
