  Abstract 


Ocular trauma is a disabling but preventable cause of blindness which can lead to disproportionate personal, social and economic handicaps. This snapshot deals with individuals belonging to different cohorts: a young child and an elderly lady who inadvertently injured their eyes by thorns. Peculiarity about the thorns' trajectory was such that the large-sized thorns pierced the outer coats of the eye without actually puncturing them. Rapid diagnosis and management ensured the quick anatomic restoration and visual recovery.

Ocular thorn injury is a completely avoidable form of blindness. Early diagnosis and prompt management are must to prevent sight-threatening sequelae.

Case-1 describes a 5 year-old-male child presented with complaints of pain, watering, foreign-body (FB) sensation in the right eye (RE). His father revealed that the child injured his eye 1-day back while playing in a field. Torch-light examination showed wooden particles lodged in the cornea with conjunctival congestion and apparently formed anterior chamber (AC). Being uncooperative for visual acuity (VA) assessment and slit-lamp examination (SLE), an examination under general anesthesia was carried out. Under microscope [Figure 1], two thorns were noted, the larger one had created a partial-thickness corneo-limbo-scleral tract at 2 O'clock with surrounding infiltrates. The smaller one had penetrated into the AC creating a valvular wound. Fortunately, the lens was clear and limited view during fundoscopy showed unremarkable posterior segment. Both thorns were extracted out followed by the application of 10-0 Nylon sutures on the entry wound and side-port. Routine postoperative medications including topical Natamycin (5%) two-hourly were administered. Corneal infiltrates resolved in follow-ups and sutures were removed at 6-weeks, following which the child achieved the best-corrected VA of 20/20.

Case-2 shows a 60 year-old-female who injured her RE by a thorn while working in a farmland 2 days back. She presented with complaints of pain, FB sensation and redness. SLE revealed a wooden-particle having pierced conjunctiva and probably sclera temporally, roughly at 10 mm posterior to limbus without compromising globe integrity. There was diffuse conjunctival congestion and senile cataract, but otherwise normal anterior and posterior segments. Uncorrected-VA was 20/60 and IOP was 16 mmHg. B-scan showed no internal breach. The patient was taken to the operation theatre. Under peribulbar anaesthesia, the FB was grasped, gently manoeuvred and brought out of the wound in-toto [Figure 2]. It was a thorn, 8 mm in length and had partially lacerated the sclera. A (8-0) vicryl suture was applied at the partial-thickness scleral wound followed by conjunctival closure. Routine postoperative medications were administered. She had uncomplicated follow-ups and maintained the same vision and was advised to undergo cataract surgery later.

Both cases are interesting since the large-sized thorns had created lamellar tract in structures as thin as the ocular surface (sclera/cornea) without actually perforating it.

Ocular thorn injuries can result in conjunctival granuloma, fungal keratitis, AC perforation, traumatic cataract, vitritis, or even endophthalmitis.[1],[2]

However, as the saying goes “Ounce of prevention is worth a pound of cure”, proper use of safety goggles at the workplace and restriction of unsupervised activities by children will drastically reduce the incidence of ocular trauma.[3]
