Percutaneous radiofrequency ablation of the Gasserian ganglion or posterior root, or both, was performed in 140 patients. Of the 135 patients with trigeminal neuralgia, satisfactory analgesia was achieved in 121. Postoperative complications included unintentional first-division analgesia (10), transient sixth-nerve palsy (1), neuroparalytic keratitis (2), and anesthesia dolorosa (2). The phenomenon of facial blush may be helpful in avoiding unwanted first-division analgesia. In four of five patients with other forms of neuralgia, the procedure did not relieve pain; the fifth patient experienced significant relief from pain due to carcinoma of the mandible.

Four hundred and forty ocular and orbital tumours seen in Ibadan over 11-year-period (1980-1990) are reviewed. Three quarters of the 252 patients who had enucleation had malignant neoplasms, of which 55% were retinoblastomas. The mean age of patients with retinoblastomas (3.2 years) was less than that of patients with carcinoma and malignant melanomas (47 years). Malignant melanomas were rare neoplasms in Ibadan. The commonest orbital lymphoma was Burkitt's lymphoma. Only 24% of the enucleated eyes had inflammatory conditions, of which 38% gave a positive history of trauma. Inflammatory lesions were the commonest benign ocular diseases accounting for 33% of these latter cases. Postmeasles keratitis was a significant associated finding in these patients.

An 81-year-old man with metastatic prostate carcinoma underwent a penetrating keratoplasty for phlyctenular keratitis. Two years later he developed a fleshy, vascular mass in the superotemporal corneal graft wound, at the site of prior graft sutures. An excisional biopsy of the mass was performed to rule out metastatic carcinoma. Histopathological findings were consistent with pyogenic granuloma. To our knowledge there have been no prior case reports illustrating pyogenic granuloma as a late complication of penetrating keratoplasty.

Dendritic herpetic keratitis developed in a 49-year-old patient during topical acyclovir treatment. A positive herpes simplex culture was obtained. After acyclovir was replaced by trifluorothymidine and interferon, the dendritic lesion disappeared and herpes simplex culture became negative. Six months later a carcinoma of the larynx was diagnosed. The acyclovir-resistant herpetic keratitis may be associated with the carcinoma because resistant herpes simplex virus strains are predominantly described in patients suffering from immune deficiency.

We describe 2 cases of the rare entity of bilateral infiltration of the eyelids by metastatic breast carcinoma. In 1 case, this was the first manifestation of the tumor. Both women had ptosis and lagophthalmos with secondary exposure keratitis.

Because of the wide variety of x-rays now available, selectivity is possible and important in treatment of diseases of the eye. By the use of short-range radiation, newly developed eye shields and the insulation of the eyelid itself, and by careful angulation of the beam, the desired irradiation can be given where it is needed without injury to surrounding tissues. The authors have found the 50 kv x-ray unit to be the most reliable and adaptable for most circumstances. The skin of the eyelid reacts to irradiation more sensitively than other tissues. The cornea reacts with keratitis and sometimes intractable ulceration. The iris, uveal tract and retina are less seriously affected. At the University of California Hospital irradiation has been found satisfactory for treatment of corneal ulcer, keratitis, pterygium, certain types of conjunctivitis, episcleritis, corneal vascularization, iritis, uveitis, and hemangioma. Irradiation may be of great benefit in absolute glaucoma with pain and blindness. Of 42 patients with carcinoma of the eyelid treated between 1935 and 1946, 27 had no recurrence in five years, 5 had recurrence, 7 died of other causes and follow-up was incomplete on 3. Good cosmetic result was usually achieved. No recurrence has been observed in 22 patients treated since 1946. Irradiation has been used with success in other kinds of cancer of the eye structures.

Using an appropriate animal model is crucial for mimicking human disease conditions, and various facets including genetics, anatomy, and pathophysiology should be considered before selecting a model. Rabbits (Oryctolagus cuniculus) are well known for their wide use in production of antibodies, eye research, atherosclerosis and other cardiovascular diseases. However, a systematic description of the rabbit as primary experimental models for the study of various human infectious diseases is unavailable. This review focuses on the human infectious diseases for which rabbits are considered a classic or highly appropriate model, including AIDS (caused by HIV1), adult T-cell leukemia-lymphoma (human T-lymphotropic virus type 1), papilloma or carcinoma (human papillomavirus) , herpetic stromal keratitis (herpes simplex virus type 1), tuberculosis (Mycobacterium tuberculosis), and syphilis (Treponema pallidum). In addition, particular aspects of the husbandry and care of rabbits used in studies of human infectious diseases are described.

Herpesviruses infect the majority of the human population and can cause significant morbidity and mortality. Herpes simplex virus (HSV) type 1 causes cold sores and herpes simplex keratitis, whereas HSV-2 is responsible for genital herpes. Human cytomegalovirus (HCMV) is the most common viral cause of congenital defects and is responsible for serious disease in immuno-compromised individuals. Epstein-Barr virus (EBV) is associated with infectious mononucleosis and a broad range of malignancies, including Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's disease, and post-transplant lymphomas. Herpesviruses persist in their host for life by establishing a latent infection that is interrupted by periodic reactivation events during which replication occurs. Current antiviral drug treatments target the clinical manifestations of this productive stage, but they are ineffective at eliminating these viruses from the infected host. Here, we set out to combat both productive and latent herpesvirus infections by exploiting the CRISPR/Cas9 system to target viral genetic elements important for virus fitness. We show effective abrogation of HCMV and HSV-1 replication by targeting gRNAs to essential viral genes. Simultaneous targeting of HSV-1 with multiple gRNAs completely abolished the production of infectious particles from human cells. Using the same approach, EBV can be almost completely cleared from latently infected EBV-transformed human tumor cells. Our studies indicate that the CRISPR/Cas9 system can be effectively targeted to herpesvirus genomes as a potent prophylactic and therapeutic anti-viral strategy that may be used to impair viral replication and clear latent virus infection.
