Focal Posttraumatic Choroidal Granulomatous Inflammation
MATTHEW W. WILSON, MD., HANS E. GROSSNIKLAUS, MD., AND J. GODFREY HEATHCOTE, MB.
PURPOSE: This study was performed to describe the clinicopathologic features of a group of patients with posttraumatic unilateral focal choroidal granulomatous inflammation. METHODS: Enucleated eyes with focal choroidal granulomatous inflammation without clinical signs of contralateral ocular inflammation were identified. Clinical and pathologic features were recorded. RESULTS: Six enucleated eyes that had been injured by projectiles had focal uveal granulomatous inflammation of the posterior choroid. Four eyes had uvea attached to or incarcerated into the wound. Two eyes had foreign material associated with the granulomatous inflammation, and two eyes had a disrupted lens with lens-induced inflammation. Two eyes exhibited the focal granulomatous inflammation at the site of a choroidal rupture None of the six enucleated eyes contained Dalen-Fuchs' nodules. CONCLUSIONS: Focal choroidal granulomatous inflammation may occur as a result of penetrating ocular trauma. The origin of this condition is unknown, although it likely represents a reaction to a foreign body.

WE IDENTIFIED SIX CASES OF CLINICALLY UN-suspected posttraumatic choroidal granulomatous inflammation. All cases occurred after severe ocular injuries, with each eye undergoing primary repair. All eyes were enucleated within two weeks of initial injury because of poor visual prognosis and the risk of sympathetic ophthalmia. All fellow eyes lacked clinical signs of inflammation. The granulomatous inflammation in the traumatized eyes was focal and minimal. We studied the clinicopathologic findings of these six eyes and determined the possible origin of this posttraumatic focal choroidal granulomatous inflammation.
MATERIAL AND METHODS
BETWEEN 1941 AND 1994, 963 POSTTRAUMATIC ENUCLE-
ated eyes were accessioned in the L. F. Montgomery Ophthalmic Pathology Laboratory, Emory University, Atlanta, Georgia. Six enucleated eyes with the pathologic finding of focal choroidal granulomatous inflammation were retrieved from the group of 963 eyes. Clinical histories and ophthalmic examinations of the six patients with posttraumatic focal choroidal granulomatous inflammation were studied. We stained ten 5^m-thick step sections through the center of the enucleated eyes with hematoxylin and eosin and examined them.
ALL CASES OF GRANULOMATOUS INFLAMMATION Occurred after 1990. All patients were male, and ages ranged from 8 to 34 years (Table 1). All of the

traumatized eyes were left eyes. All injuries were by projectiles, and all eyes were enucleated within two weeks of injury. There was uvea associated with the wound in four eyes, and four eyes were perforated (Table 2). The lens was disrupted in four eyes, with inflammation associated with lens material in two eyes. There was pigment phagocytosis by histiocytes in four eyes and foreign material in two eyes. No eyes contained Dalen-Fuchs' nodules, bacteria, or fungi. None of the patients had any evidence of sarcoidosis or other granulomatous disease. No patients had received immunosuppressive medications.
CASE i: A 34-year-old man sustained multiple gunshots to the head, neck, and chest. The left eye
was perforated by buckshot. Visual acuity was R.E.: 20/20 and L.E.: no light perception. A limbal entrance wound was noted. Computed tomography showed that the buckshot exited posteriorly, nasal to the optic nerve. The anterior wound was repaired and, postoperatively, visual acuity was no light perception in the left eye. The blind left eye was enucleated nine days after the initial injury. The right eye retained visual acuity of 20/20, with no inflammation two weeks postoperatively. The patient failed to return for follow-up examination.
Microscopic examination of the enucleated eye disclosed a full-thickness limbal wound with incorporation of pigmented uveal tissue. The iris was intact and the ciliary body was partially avulsed. The lens was disrupted with an associated granulomatous inflammatory response, including pigment-laden foreign body giant cells (Fig. 1). The vitreous was hemorrhagic and contained lens remnants. The retina was dialyzed. The choroid was ruptured near the optic nerve and exhibited focal granulomatous inflammation with associated eosinophilic debris (Fig. 2). No Dalen-Fuchs' nodules were present. The underlying sclera was torn. The optic nerve head was edematous and contained a mild inflammatory infiltrate. Results of special staining for bacteria and fungi were negative.
CASE 2: A 14-year-old boy sustained a penetrating BB injury to his left eye. The BB entered the eye through the inferocentral cornea. The BB was removed and the wound was repaired. Three days after the injury he underwent a vitrectomy and placement of a scierai buckle with injection of intravitreal antibiotics for possible endophthalmitis. Postoperative

Microscopic examination of the enucleation specimen showed a full-thickness corneal wound with vascularization of the stroma, suture material, and an associated foreign body giant cell reaction. The iris was adherent to the posterior corneal surface, thus occluding the trabecular meshwork. The iris and

CASE 3: A 16-year-old boy sustained a perforating injury to his left eye from a pellet gun. Examination showed visual acuity of R.E.: 20/40 and L.E.: possible light perception. His ocular history was remarkable for amblyopia in his right eye. A
