Ophthalmomyiasis interna [Figure 1] is a rare infestation of the retina and vitreous due to larvae of a fly. The larvae penetrate inside the eye and migrate in the subretinal space resulting in hypopigmented tracks. They appear hyporeflective on optical coherence tomography and hyperfluorescent on fluorescein angiography. Live larva if seen in the subretinal space can be immobilized and killed by focal laser before more damage is done. Larvae can burst into the vitreous cavity. Dead larvae can cause severe vitritis, fibrovascular proliferations, focal hemorrhages, or disc edema. Vitrectomy can be performed for these complications. Ivermectin is effective against active larval infection.
Figure 1: A 52-year-old woman reported a 3-year history of severe vision loss to counting fingers in the left eye. Multiple subretinal, depigmented tracks were visible in the left eye mainly around the macular area along with a large, full-thickness macular hole. The tracks were confluent in the inferior macular area. They resembled the larval migration tracks seen in ophthalmomyiasis interna. No larva could be identified. No antibiotic treatment was given as there was no active infection seen. Due to the extensive subretinal scarring, surgery for the macular hole was deferred
