Design- Descriptive study Animals- 12 short haired “Tomcats” weighted about 3.9± 0.9 Kg no e general and optic disease in clinical, paraclinical and ophthalmoscopic examinations. Pr...

Nail histopathology.

The structure of the nail unit is complex and many dermatologists and dermatopathologists have an incomplete understanding of it. Familiarity with the anatomy and histology of this unit, however, is a key factor in improving the diagnostic yield of nail biopsy. Inflammatory or infectious conditions that affect the nail can have a marked impact on a patient's quality of life. A wide-ranging vari...

Ophthalmic Ultrasound

In 1956, Mundt and Hughes used an A-scan on an intraocular tumor, demonstrating the possible use of ultrasound in ophthalmology. Soon a body of research developed on the sound velocities of various tissues and compartments of the eye, and in the 1960s, ultrasound began to be used to measure distances in the eye. B-scan instruments developed in the 1970s, were originally used through closed eyel...

Ophthalmic Pterygium

Pterygia are common ocular surface lesions thought to originate from limbal stem cells altered by chronic UV exposure. Traditionally regarded as a degenerative condition, pterygia also display tumor-like features, such as a propensity to invade normal tissue and high recurrence rates following resection, and may coexist with secondary premalignant lesions. This study was initiated to determine ...
