Orbital NHLs are rare and manifest themselves primarily in localized stages. The value of radiotherapy is discussed, reviewing retrospectively the treatment results obtained in 41 patients irradiated for orbital NHL between 1958 and 1966. All were histologically verified. There were 15 lymphomas of low and nine of high malignancy according to the Kiel classification. Among the 17 remaining patients, 15 cases had been classified as reticulum cell sarcoma and two as lymphosarcoma. Fourteen cases were in stage IE, 19 in stage IIE, and eight in stage IIIE/IVE. After surgical biopsy (n = 25) or resection (n = 5), megavoltage irradiation was delivered in conventional fractionation from 20 Gy up to a total dose of 50 Gy. During the last decade treatment has been based on CT scans and corresponding computer assisted treatment planning. Clinically, complete remission was achieved in 13 out of 14 patients (93%) with stage IE, in 17 out of 19 patients (90%) with stage IIE, and in five out of eight patients (63%) with stage IIIE/IVE. The nonrecurrence rate is 65% (10 out of 14) for stage IE and 75% (13 out of 17) for stage IIE after a mean follow-up time of 36 months. As regards lymphomas of low and high malignancy, the nonrecurrence rate is 89% and 43% respectively. Recurrence (n = 8) and dissemination (n = 6) occurred only twice more than two years after radiotherapy had been discontinued. The incidence of side effects was low. Two patients developed a "dry eye." In two eyes the lens had to be removed because of progressive cataract. Radiotherapy with individual treatment planning based on CT scans is the curative treatment of choice fo localized orbital NHL.

Uveitis is one of the most common ocular diseases and one of the most common causes of blindness in dogs. The purpose of this retrospective study was to correlate the signalment, history, clinical signs and ophthalmic findings of dogs with uveitis with the underlying etiology. We conducted a retrospective study of 102 dogs presented to the NCSU-VTH from 1989 to 2000 with clinical signs of uveitis. Medical records of dogs presented for uveitis were reviewed. Dogs were included in the study only if a complete diagnostic work-up database was collected, if sufficient follow-up was documented, and if the uveitis was not secondary to trauma or a hypermature cataract. The mean age +/- SD of all dogs in this study was 6.2 +/- 3.6 years. There were 33 intact and 16 castrated males, and 14 intact and 27 neutered females. Fourteen breeds were represented, with the Golden Retriever (n = 14) most common. Fifty-nine dogs (58%) were diagnosed with idiopathic/immune-mediated uveitis, neoplasia was diagnosed in 25 dogs (24.5%) and 18 dogs (17.6%) were diagnosed with infectious causes of uveitis. Aqueous flare was the most common clinical sign, occurring in 88 dogs (86%). The most common infectious organisms associated with uveitis in the dogs of this study were Ehrlichia canis (n = 7). Lymphosarcoma (n = 17) was the most common neoplasm. In approximately 60% of dogs presenting for uveitis an underlying cause was not found, and a diagnosis of immune-mediated or idiopathic uveitis was made. However, approximately 25% of dogs had ocular and/or systemic neoplasia (with 17% of cases having lymphosarcoma) and 18% with an underlying infectious cause for uveitis. Because of the high percentage of systemic disease associated with uveitis in dogs, extensive diagnostic testing is recommended before instituting symptomatic anti-inflammatory therapy.
