A 42-two-year-old male—a laborer by occupation—presented with chief complaints of foreign body sensation and conjunctival redness in the right eye. A month ago, the patient underwent ocular trauma while working at the construction site. He consulted a nearby vision center. The patient was managed conservatively on an antibiotic and steroid combination for four weeks but was later referred to a higher center due to persistent congestion. On examination, his visual acuity was 20/20 in both eyes, but there was the presence of mild conjunctival congestion in the right eye. Intraocular pressure was 14 mmHg in both eyes. On slit-lamp evaluation, a self-sealed corneal perforation of 1.5 mm was noted in the right eye; Seidel's test was negative and the anterior chamber showed occasional cells and a solid creamy white lesion at the 6 o'clock position [Figure 1]a. Anterior segment examination of the left eye was within normal limits. Fundus examination was also unremarkable in both eyes. X-ray orbit showed the presence of a foreign body [Figure 1]. However, the exact location could not be determined. Therefore, a gonioscopy of the right eye was performed, which revealed a suspicious foreign body lodged in the inferior angle [Figure 1]b. The findings were confirmed on anterior segment optical coherence tomography (ASOCT) [Figure 1]c. On surgical exploration, a metallic foreign body of 2.5 mm in largest diameter was retrieved from the inferior angle [Figure 1]e. | Figure 1: (a) Solid, creamy, white mass lesion at 6 o'clock position (arrow) and self-sealed corneal perforation (arrowhead) seen on slit-lamp evaluation.

Penetrating ocular trauma is a potentially vision-threatening injury, and retained intraocular foreign bodies often pose a significant challenge to the treating ophthalmologist.[1],[2] If undetected, they may present with persistent or recurrent inflammation in the eye. Our case is unique as the foreign body was diagnosed only after one month with the help of gonioscopy.[3],[4]
Besides, radiological investigations like X-ray, ancillary investigations, gonioscopy, ultrasound biomicroscopy, and ASOCT should be done in suspected cases to rule out any retained foreign bodies in angles. These tests not only aid in diagnosing metallic and non-metallic foreign bodies but are also helpful in determining their exact location. However, among them also, gonioscopy is the cheapest and most readily available investigation.
