https://www.selleckchem.com/products/cc-885.html The purpose of this case report is to demonstrate the efficacy of an asymmetric peripheral design scleral contact lens in a case of highly irregular corneal-scleral pattern due to trauma. A 63-year-old patient was involved in a jeep accident which caused a partial-thickness penetrating injury to the peripheral cornea of his left eye. The subsequent corneal irregularity extended beyond the limbus into the sclera which made it difficult to stabilize a contact lens. A quadrant specific peripheral curve (quadrant asymmetric periphery) scleral contact lens successfully resulted in improved comfort and visual acuity. This is the first known published case to use this lens design to correct a post-trauma irregular cornea-scleral relationship. Quadrant asymmetric periphery scleral contact lenses can be effective in cases of severe irregular corneal-scleral patterns.Herein, we report a case of acute failure of a previously successful trabeculectomy, following an infection with herpes zoster ophthalmicus (HZO). HZO remains a common infection, especially among elderly and immunocompromised patients. There is a strong link between HZO infection, the incidence of secondary glaucoma, and the need for glaucoma filtering surgery. Though, to our knowledge, there are no cases reporting on the effect that a concomitant infection may have on a previously successful trabeculectomy. In our case, a 76-year-old immunocompetent male with primary open-angle glaucoma in both eyes and a history of a successful right eye trabeculectomy 1 year earlier presented with acute primary HZO involving the ophthalmic branch of the right trigeminal nerve. Appropriate topical and systemic treatment was immediately initiated. Three days later, the trabeculectomy bleb showed hyperemia and flattening and concomitant rise of intraocular pressure was noted. A week later, the cutaneous signs were improving yet the trabeculectomy had failed and high intraocular pre
