RESUMO
This article describes the nonablative laser and light source technologies that are currently available for the rejuvenation of photodamaged skin. A brief overview of the etiology of solar skin damage is followed by an explanation of how nonablative technologies induce repair of photoaged skin. An overview of the various light sources is provided, with particular attention to their mechanism of action and clinical use.

The oculo-facial surgeon's quest for non-invasive procedures is a response to increasing patient demands for enhanced results without any downtime. Technology has obliged us with multiple injectable and light therapeutic modalities that tighten skin, relax and fill in wrinkles, and improve skin dyspigmentation and texture. When these techniques are combined, the results are superior to the use of individual therapies alone. The foundation for combination therapies are: botulinum toxin, filling agents, chemical peels, intense pulsed light, non-ablative and ablative lasers.

A 39-year-old black man with sickle cell trait presented with a rapidly progressive, painful proptosis of the left eye. A computed tomographic scan was interpreted as revealing a cavernous hemangioma. Medial orbitotomy revealed a hard, gray mass supranasal to the optic nerve and invading the medial rectus muscle. Intraoperative frozen section specimens were read initially by the pathologist as metastatic adenocarcinoma. On gross examination, the conspicuous hemorrhage, necrosis, and bright yellow color characteristic of renal cell carcinoma were not present. Final pathologic analysis of the orbital lesion revealed metastatic renal medullary cell carcinoma. The primary lesion was located in the right kidney. Renal medullary carcinoma is a rare tumor, often affecting young individuals with sickle cell trait or disease. We report the first confirmed case of renal medullary carcinoma metastatic to the orbit with orbital symptoms preceding the diagnosis of the primary tumor.
