The use of eye cosmetics is a popular practice in modern times that dates back to ancient civilizations. This practice, however, is not without hazards. The most common adverse effect of eye cosmetics is eyelid dermatitis, although an array of other adverse effects has been reported. This article reviews the different types of eye cosmetics in current use, their composition and the adverse effects of both commercial and traditional products.
PURPOSE: To describe a modified technique for performing sutureless sclerotomies for pars plana vitrectomy and to examine its efficacy and safety. DESIGN: Retrospective, interventional case series. METHODS: Self-sealing sclerotomies were created in 35 consecutive cases by oblique penetration of the sclera with a 19G MVR blade. RESULTS: All but two (2.9%) of the sclerotomies were watertight without suturing at the end of surgery. A conjunctival bleb was observed during the first postoperative week in one case, but it resolved without intervention. CONCLUSIONS: Construction of sutureless sclerotomies by this technique is simpler and more rapid compared with previously described techniques. The resulting sclerotomies are more resistant to stretching and tearing of the tunnel's roof, they rarely need suturing, and insertion of instruments is facilitated.
PURPOSE: To describe an unusual case of idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome with rapid dynamics in the number and appearance of the aneurysms. DESIGN: Observational case report. METHODS: Clinical and angiographic data of the patient were reviewed. RESULTS: In the course of only 6 months, preexisting retinal aneurysms resolved while new ones appeared. Changes were observed in the shape and size of preexisting lesions. The resolution of lesions in eyes previously untreated by laser is reported for the first time. CONCLUSIONS: Vascular lesions in IRVAN syndrome may show an unusually rapid turnover. The resolution of aneurysms is a part of the natural course of the disease and may occur without previous retinal laser photocoagulation.

PURPOSE: To report the spontaneous resolution of a traumatic macular hole that was considerably larger than in previously reported cases. DESIGN: Observational case report. METHODS: The clinical and angiographic data of the patient were reviewed. RESULTS: A traumatic 600 x 400 micro macular hole was observed to spontaneously resolve 5 weeks after trauma in a 15-year-old patient. Visual acuity only slightly improved consequently (from counting fingers at 4 meters to 20/200). The clinical appearance of the fovea after macular hole resolution raised the suggestion that a postconcussion retinal necrosis was the mechanism behind the lesion formation in this case. CONCLUSIONS: Spontaneous resolution of a traumatic macular hole is an outcome not limited to small lesions. Larger macular holes may represent retinal tissue loss and consequently a less favorable visual prognosis.
