Abstract
Posterior orbital cellulitis is a clinical syndrome in which early severe visual loss overshadows or precedes accompanying inflammatory orbital signs. It is an ocular emergency that can threaten life and vision. Central retinal artery occlusion (CRAO) is a very rare condition leading to sudden onset of decreased vision and can even progress to blindness. We report a case of orbital cellulitis following Caldwell Luc surgery in a middle-aged diabetic woman, resulting in the rare complication of CRAO, leading to blindness in her right eye. The development of retinal artery occlusion after orbital cellulitis has not been well documented in literature. A quick diagnosis and close monitoring following sinus surgery is therefore needed to prevent such rare complications to happen.
Highlights
Central retinal artery occlusion (CRAO) is a very rare condition with an incidence of 1/10,000 of outpatient visits.[1]
Visual loss following orbital cellulitis can still occur despite prompt diagnosis and management
We report a rare case of CRAO with posterior orbital cellulitis in a patient operated by Caldwell Luc surgery for maxillary sinusitis
Summary
Central retinal artery occlusion (CRAO) is a very rare condition with an incidence of 1/10,000 of outpatient visits.[1]. We report a rare case of CRAO with posterior orbital cellulitis in a patient operated by Caldwell Luc surgery for maxillary sinusitis. Orbital cellulitis following Caldwell Luc procedure left eye. The patient reported to the eye department with diminished vision in the right eye. She denied perception of light in the right eye. Fundus examination of the right eye revealed disc pallor, cattle tracking of the vessels in the superior arcade. On 12 April, 2017, she denied perception of light, and fundus of the right eye (Fig. 2) revealed increased cattle tracking along the vessels and a cherry-red spot at the macula. The chemosis in the right eye had increased, pupil in the right eye was non-reacting to light and ocular movements had restricted (Fig. 3)
