The retina is the great meetting place between Ophthalmology and general medicine. So in many systemic conditions, fundus examination helps in the diagnosis and/or prognosis of the condition.
This study describes the fundus changes in patients with blood dyscrasias and attempts to answer as to about their incidences, their relationship with the different factors like blood count and their diagnostic as well as prognostic importance.
| Materials and methods|| |
Astudy of 100 patients ofvarious types and forms of the blood dyscrasias was done, when they attended M.P. Shah Cancer Hospital, Ahmedabad, or Civil Hospital, Ahmedabad.
The detailed history was taken general and ocular examinations were carried out. All the necessary investigations were done.
The pupils were dilated and direct as well as indirect ophthalmoscopic examinations were done. Note was made of any abnormalities in media, appearance of disc and blood vessels and of the presence and haemorrhages and exudates. Whenever possible, the retinal abnormalities were photographed.
| Observations|| |
The proportion of patients with retinal abnormalities in each group is shown in [Table - 1] out of 100 patients. 50% are of leukemias, 40% are of all types of anemias and remaining 10% are of leukopenia, purpura, polycythaemia and hemophilia. It shows that all types of leukaemia constitute a major group in various types of blood dyscrasias and next is anaemia.
The higher incidence of retinal haemorrhages is seen in leukaemia while the pallor of disc is seen more commonly in anaemias.
Anaemias: Only 6 out of 40 patients had retinopathy and all these were severely anaemic. But the appearance of pale disc was seen in 18 patients. It seems that severely anaemic patients with Hb less than 3 gm% and R.B.Cs. count less than 2 million/cmm were more likely to develop fundus changes.
The retinal abnormalities were invariably cleared on treatment.
[Table - 5][Table - 6][Table - 7][Table - 8][Table - 9] show comparison of Hb cone, platelet count, blast cells and W.B.C. count with retinal changes in patients of acute and chronic leukaemias. The number in brackets indicating no. of patients having retinal lesions.
Eighteen out of 33 patients had a retino pathy. The retinal abrnomalities showed no distinguishing features. All the patients were having flame shaped and discrete haemorrhages and 3 developed subyhyaloid haemorrhages. The haemorrhages in a number of patients had white centres, but these were not related to a high total white cell count.
As shown in [Table - 5][Table - 6][Table - 7][Table - 8] retinopathy was observed when the patients were more anaemic and had a lower platelet count and a higher percentage of circulating blast cells. No significant correlation between the presence of retinopathy and the W.B.C. count could be established.
The survival of patients with retinal abnormalities did not differ significantly from those in whom the fundus oculi was consistently normal.
Ten out of sixteen patients were having retinal haemorrhages and dilated tortuous veins. The presence of retinopathy did not depend upon the platelet count or white blood cell count but occurred at a lower Hb. concentration. The prognosis of patients with retinopathy was no worse than that of those without it.
Other Blood Diseases:
The number of other cases being very less no definite conclusion can be drawn. But the observations were that:
a) In Leukopenias and hemophilia retinopathy is rare.
b) While in polycythaemia retinal haemorrhages are common.
c) Retinopathy occurs more frequently when platelet count is less than 1 lac/cmm and Hb less than 3 gm%.
| Summary|| |
The fundus oculi of 100 patients with blood diseases seen at the M.P. Shah Cancer Hospital, Ahmedabad and a Civil Hospital, Ahmedabad, were carefully examined in
order (a) to define the incidence of retinopathy in various disorders of blood, (b) to determine the diagnostic and/or prognostic importance of lesions seen and (c) to relate the abnormalities found to the blood count.
Retinal haemorrhages were more common in lenkaemias, while the pale disc was the unique feature of severe anaemias. The retinal abnormalities had no characteristics of diagnostic and/or prognostic significance.
