Differential diagnosis of lower eye lid swelling
lower eyelid swelling infraorbital ecchymosis periorbital edema

This clinical photograph shows a close-up, frontal view of a patient's periorbital region, demonstrating unilateral ecchymosis of the left lower eyelid. A white arrow points to a localized area of significant skin discoloration characterized by deep purple and blue hues, transitioning into yellowish-green tones at the periphery, indicative of blood extravasation in different stages of breakdown. There is associated mild edema and a palpable nodular mass noted in the clinical history, though only the superficial bruising and slight swelling of the infraorbital soft tissue are visually evident. The right eye and periorbital area appear normal, providing a clear comparison of the pathology. This image is used to illustrate clinical findings associated with orbital trauma or an occult foreign body, emphasizing the importance of detailed physical examination and imaging in cases of localized periorbital bruising.

This clinical photograph displays a frontal view of a patient's midface, focusing on the left periorbital and suborbital regions. The image demonstrates significant moderate edema (swelling) and extensive ecchymosis (bruising) localized to the left suborbital area and the lower eyelid, characterized by deep purple and reddish discoloration. A linear incision site is visible at the lateral aspect of the infraorbital rim, secured with medical skin sutures, indicating recent surgical intervention. The surrounding facial skin shows generalized erythema, potentially reflecting inflammatory changes or trauma-induced irritation. The contralateral (right) side of the face appears unremarkable, providing a baseline for assessing the unilateral swelling and facial asymmetry. Clinically, this presentation is consistent with post-traumatic or post-surgical changes following a maxillofacial injury or orbital floor exploration. The visual features highlight key signs of soft tissue trauma and the immediate postoperative state of the orbital frame.

This clinical photograph shows a close-up, frontal view of a 49-year-old female's mid-face, specifically the periorbital region, six days post-orbital surgery. The primary clinical focus is on the postoperative appearance of the left eye compared to the normal right eye. The left infraorbital and periorbital area exhibits significant ecchymosis and edema. A prominent yellowish-green hue (indicative of resolving bilirubin) is visible across the lower eyelid, extending toward the lateral canthus. Within this yellow region, there is a localized reddish-purple area. Inferior to this, on the malar eminence, a larger purplish-red ecchymotic patch suggests deeper tissue involvement or recent hematoma resolution. The left lower eyelid also demonstrates increased skin wrinkling and mild drooping (ectropion or pseudoptosis due to swelling) compared to the contralateral side. The right eye appears healthy with normal skin texture and no discoloration. This image serves as an educational tool for monitoring normal postoperative healing stages, tissue trauma recovery, and the typical color progression of bruising following ophthalmologic or orbital tumor surgery.

This clinical photograph shows a close-up frontal view of a patient's periorbital region, three weeks following bilateral blepharoplasty. The most prominent finding is severe bilateral conjunctival chemosis, characterized by translucent, bulbous swelling and elevation of the bulbar conjunctiva, making it appear thickened and puffy around the corneas. Visible erythema and vascular congestion are present in the ocular tissue. The periocular area shows typical postoperative changes, including moderate edema of the upper and lower eyelids and mild infraorbital ecchymosis (bruising) on the cheeks. Surgical adhesive tapes are applied to the lower eyelids/cheeks, and fine sutures are visible at the lateral canthi. The lower lids appear slightly retracted, likely due to the ongoing edema and surgical healing process. This image serves as an educational example of persistent postoperative chemosis, a known complication of eyelid surgery that requires clinical monitoring and potential medical or surgical intervention.
differential diagnosis lower eyelid swelling periorbital ecchymosis unilateral causes ophthalmology
| Diagnosis | Key Features | How It Fits |
|---|---|---|
| Periorbital ecchymosis ("black eye") | Blunt trauma causing blood vessel disruption; swelling + purple-brown bruising; self-resolving over 2-4 weeks | Strong match - unilateral, ecchymotic discoloration, swelling |
| Orbital fat herniation | Age-related prolapse of orbital fat through the orbital septum; bilateral but asymmetric; painless, chronic | Matches the contralateral eye's chronic puffiness with hyperpigmentation |
| Periorbital/preseptal cellulitis | Bacterial infection anterior to the orbital septum; redness, swelling, warmth, tenderness; no proptosis or restricted EOM | Less likely given the dark bruise color rather than erythema |
