A review of the literature indicates that this is a disease of infrequent occurrence. eye (1936) reported a case of a man aged 64 years who com­plained of diminution of vision of both the eyes. A retinal cyst was seen in each fundus in the lower temporal region, but there was no detachment of the retina and there was no tear.

A similar case of bilateral symmetri­cal cysts of the retina was reported by Kornzweig (1940). This was the case of a man aged 33 years who complain­ed of poor vision. In each fundus at the extreme periphery of the lower field at 6 O'clock, a spherical sharply de­fined elevation of the retina was seen. The colour of the elevation was greyish pink and the surface was slightly irregular and pitted.

Another case of bilateral symmetrical retinal cysts was reported by Paine (1955) in a man of 48 years.


  Case Report Top


Mrs. K. B. aged 23 years, married, complained of sudden diminution of vision accompanied with headache, pain and redness of both the eyes of fifteen days duration.

On examination both the eyes were congested. The pupil reacted sluggish­ly to light and accommodation. Ocular tension on the day of examination was within normal limits.

Ophthalmoscopically in the right eye the media were clear and five cystic elevations of the retina of greyish pink colour with the vessels coursing over them were seen. The cysts were located at 12, 4, 7, 9, and 11 O'clock positions. The macula could not be seen. The arteries were slightly attenuated. The disc was pinkish in colour. The fundus was studded with flame-shaped haem­orrhages and soft white exudates [Figure - 1] .

Left Eye media were clear and three cystic elevations of the retina were seen. The cysts were of greyish pink colour and the vessels were coursing on their surface. The anterior limit of the cysts could not be seen, as they were very far forwards. The cysts were located at 4, 7 and 9 O'clock positions. The fundus revealed a pinkish disc, flame-shaped haemorrhages and soft white exudates [Figure - 2].

No retinal tears could be made out in either eye.

General examination revealed an anaemic patient with a blood pressure of 162/120 mm. of Hg. The patient gave a history of having suffered from pulmonary tuberculosis in 1948 and 1950. She was treated along anti­tubercular lines. The lungs were clear when examined here.


  Laboratory Investigations Top


Urine was loaded with Albumin ( + + +) , but there were no casts of renal epithelium.

X-ray chest showed a healed lesion in the right lung.

Sputum was negative for any acid fast bacilli.

Blood Examination

Haemoglobin : 6o to 75%.

Total R.B.C.: 3.15 mill/cmm

Total W.B.C.: 13120/Cmm. with a relative leucocytosis of 72%.

E.S.R. (Westergren) : 75 mm. first hour.

The patient was put on complete bed rest and streptomycin injections and Isoniazid with Vitamin B Complex by mouth.

A tentative diagnosis of bilateral reti­nal cysts with albuminuric retinopathy was made.

After a few days it was decided to aspirate the cysts in one eye. The left eye cysts were aspirated. The aspirated fluid was straw coloured and chemical analysis indicated sugar 50 mgm. /l00cmm., proteins less than 3%. Cytology of the fluid did not indicate the pre­sence of cells. The culture of the fluid was sterile. Intradermal Casoni's test was negative.


  Discussion Top


Cyst formations along with detach­ment have frequently been reported in literature. Some of these cases have been found to occur in one eye by Ridley(1936) , (Weve (1936), Kurz (1938), and Jancke (1935). Weve (1936) reported 5 such cases where cys­tic formations were noticed in the far temporal periphery accompanied with retinal tears. Reports of infrequent occurrence of bilateral symmetrical cysts of the retina have appeared less frequently in literature by Kornzweig (1940), and Paine (1955).

Pathogenesis of bilateral retinal cysts has been rather obscure. Kornzweig (1940), Roveda and Riva (1951) re­garded them as physiological as long as they stayed as small spaces. Histo­logically these spaces commence in the inner nuclear layer. They enlarge gra­dually till they occupy the whole space between the inner and outer limiting membrane. It was also remarked by Wolff (195i) that these cystic spaces were more common on the temporal side where the teeth of the ora serrata were small. Their origin is attributed to lack of blood supply at that region. Teng and Katzin (1953), who studied a large number of normal eyes removed postmortem for the purpose of corneal grafting, showed that cystoid changes at the ora serrata are part of the ageing process and that confluence and/or dila­tion of the microcysts is of frequent occurrence.

Teng and Katzin strongly support the theory, introduced by Ochi (1927) that accommodation is responsible, by reason of the motility which it causes in the neighbourhood of the ora for the development of peripheral cystoid degeneration.

Cyst formation in the retina has also been attributed to retinal oedema, to a break down of new formed glia, after a difficult labour, iridocyclitis, perfora­ting injuries - Fuchs (1905), degene- rative conditions - Nuel, in syphilitic retinochoroiditis - Murakami (1901) and glaucoma - Holmes, Spicer and Parsons quoted by Wolff (1951).

Retinal folds occasionally occur in the early life of the embryo, specially near the ora serrata. It is possible that in rare cases such a told persists in adult life and at some period the space bet­ween the two layers of the folds en­larges to become a cyst (Elwyn 1947) A bilateral symmetrical situation of such embryonic folds which later develop into cysts is possible.

In the case described I am of the opinion that the patient did have reti­nal cysts of a small size to start with. The size being small, the patient never noticed any change in vision. As to the etiology of the cysts, it is conjectured that most likely it was a developmen­tal anomaly to start with. Superimpo­sed inflammation (albuminuric retino­pathy) and anaemia caused a degenera­tive enlargement of the cyst, so much so as to interfere with vision. This sudden enlargement is however, un­explainable. It is quite possible though that the cysts may have been enlarging gradually, and, it was after the onset of retinopathy with papilitis that the patient became conscious of the dimi­nution of vision. Francois and Rabaey (1953) regard such cases as exaggerations of peripheral cystoid degenerations.

Another interesting feature is the simultaneous onset in both the eyes. It may be pointed out that even in the retinal detachments affecting both eyes, usually there is an interval between the occurrence of the detachment in the first and the second eye, - Elwyn (1947). It is interesting to note that in such cases the tears and holes in the retina are frequently of the same kind in both the eyes and are often situated in symmetrical areas. These interesting points have been pointed out by Elwyn (1947), Bartel (1936), Gonin (1934) Arruga (1949), De Roth (1939), Gifford (1936), and Dunnington and Macnic (1935).


  Summary Top


1. A case of bilateral retinal cysts is described and illustrated.

2. The age and sex of the patient indicates that the occurrence of bila­teral cysts as reported in literature has no bearing on the disease.

3. The probable etiology in the face of lack of pathological evidence seems to be a developmental anomaly with a superimposed inflammation.

4. A brief review of the literature is given. It is pointed out that very few cases in literature have been record­ed of bilateral retinal cysts.
