The protein content of the aqueous rises significantly in uveal inflammation, mostly due to increased permeability of anterior uveal capillaries. There are some evidences to suggest that immunoglobulines may be getting manufactured in the uveal tissue as a local immulogic response to a variety of antigen including lens proteins. Besides, ocular inflammation does influence the globulin factors in the circulating serum. Thus, a qualitative analysis of protein fraction of aqueous and serum is expected to be valuable in the understanding of pathophysiology of uveitis.
With this background the present work was undertaken.
| Material and methods|| |
All cases were adults. Following groups of cases were taken for study:
(1) Traumatic iritis with macroscopic and microscopic hyphaema (10).
(2) Post traumatic lens induced uveitis with escape of lens matter in anterior chamber. In this group hypermature cataract with lens induced uveitis and secondary glaucoma were also included (15).
(3) Uveitis of non-specific nature; both recurrent and with hypopyon (5).
(4) Control group of senile cataract cases (20).
In each case 2 specimens were:
1. Aqueous was withdrawn by an ordinary syringe and needle.
2. 5 ml. blood from same patients was collected for the serological tests.
(i) Sera and aqueous were subjected to electrophoresis.
(ii) The sera of patients were tested for compliment fixing antibodies against lens proteins in cases of traumatic uveitis and also against non specific antigen in cases of other uveitis.
No significant difference was seen between age group and sex hence these factors were eliminated from report.
The results of CFT and RBC agglutination ran almost parallel to each other. At times CET appeared simpler, more sensitive as well as more specific for antibodies.
| Conclusions|| |
1. An effort has been made to recognise and isolate presence of immune responsible gamma globulins in cases of uveitis than simple mention of proteins as a result of inflammation.
2. Electrophoretic pattern of aqueous protein is slightly different in cases of nongranulomatous as against lens induced granulomatous response. There being no protein in normal subject, the bands are absent.
3. Presence of gamma globulins in aqueous in all types of uveitis cases is indicative of local immunological response of uveal tissue to different antigen (T cell immune response) and there being no effect in titre of compliment fixing antibody of serum, as, response is not humoral, except that of lens induced variety where compliment fixing antibodies are present in all cases.
4. Presence of compliment fixing antibodies in serum in cases of lens induced uveitis seems to be a humoral response and chain of B-cell mediated response is affected producing circulating antibodies. This explains the hypersensitivity of uveal tissue in non-injured eye in case of sympathetic ophthalmitis as reported by other workers.
5. Electrophoretic bands of aqueous in traumatic uveitis with hyphaema and serum were similar probably because of presence of blood in aqueous.
| Summary|| |
A simple technique of recognising gamma globulin has been described. Work for specific varieties of antibodies and positive control is still in progress.
