Brown leaves or flowers with white or dark spots can result from a fungal infection in the plant. Fungal infections are often a result of soil that is too moist, or of leaves and flowers that are damp from watering or humidity.
Endolaryngeal microsurgery using a direct straight laryngoscope is a well-established procedure in phonosurgery. It enables the surgeon to perform a precise, exact procedure using the microflap technique for the treatment of small lesions in the vocal folds, such as cysts and polyps.
Your ophthalmologist may be able to create thinner flaps (less than 160 micrometers thick) with either the femtosecond laser or with special types of microkeratomes. Alternatively, you may wish to consider undergoing surface-based laser refractive surgery, where no corneal flaps are created.
