India. Third molar extraction remains one of the most common surgical procedures performed in dentistry either by intra-alveolar or trans alveolar methods; yet such a common surgical procedure sometimes results in relatively rare complications. The incidence of complications can be reduced by proper preoperative planning, knowledge of the surgical anatomy, good surgical technique and recognition of complications. Sub conjunctival haemorrhage after maxillary third molar extraction is one such complication, which till now not more than three cases of similar findings have been reported in the literature. The purpose of this article is to present a rare case of sub conjunctival haemorrhage after maxillary right third molar extraction in a 56-year-old female reported at The Department of Oral and Maxillofacial Surgery, Sri Manakula Vinayagar Medical College and Hospital, Pondicherry, India. A 56-year- old female reported to the Oral and Maxillofacial Surgery outpatient clinic at the Sri Manakula Vinayagar Medical College and Hospital a day after having her right maxillary third molar extracted by a general dentist with the complaints of mild swelling in right mid face region and redness in her right eye (Figure. 1a & 1b). Detailed history revealed that the patient noticed redness in her right eye on the day of the extraction of her right maxillary third molar. Extraction was performed under local anaesthesia with adrenaline (2 % lidocaine and 1: 200000 adrenaline). Her vital signs recorded were unremarkable and within normal limits. Patient medical history was unremarkable and did not have any history of systemic diseases such as diabetes, hypertension, and bleeding disorders. Extraoral examination revealed mild swelling in right midface region and diffuse Sub conjunctival haemorrhage in her right eye without any disturbances in vision and eyeball movements. Intraoral examination revealed normal-appearing mucosa and healing extraction socket in the right maxillary third molar region. Computed tomogram scan was taken which showed enlarged right superior ophthalmic vein without any signs of maxillary tuberosity fracture and optic nerve compression (Figure. 2). Ophthalmologist opinion was obtained; a conservative approach with antibiotic eye drops and lubricants were prescribed. Close monitoring of the patient’s vision was regularly carried out; there was a significant reduction in sub conjunctival haemorrhage over the next 5 days.
