Intra-lenticular caterpillar seta in ophthalmia nodosa.

PURPOSE: To report the clinical course of ophthalmia nodosa with a retained lenticular seta misdiagnosed and treated as non-infectious posterior uveitis for 7 consecutive years.

METHODS

Meticulous clinical examination led to discovery of the caterpillar seta embedded in the crystalline lens and the intravitreal setae.

RESULTS

Lens-sparing pars plana vitrectomy and removal of free-floating vitreal seta resulted in complete resolution of vitritis and uveitis.

CONCLUSION

Embedded seta within a clear lens may remain sequestered, and may be left untouched under close observation, precluding a clear lens extraction in such patients.
