Basu A. Central retinal artery occlusion. Indian J Ophthalmol 1974;22:33 |
The effect of central retinal artery obstruction, as Duke Elder [1] describes, is sudden, complete and permanent blindness unless the obstruction is of short duration.
As a rule the macula, owing probably to its precarious blood supply and highly specialised nature, is early affected, and remains permanently functionless unless the obstruction is of comparatively of short duration. [2],[3]
The present case of central retinal artery occlusion is of interest because of the recovery of central vision even after 26 hours of obstruction.
| Case Report | |  |
Miss S., aged 21 years attended the eye department on 24.1.74 with the complaint of sudden loss of vision left eye since yesterday morning. On examination her left pupil was dilated and not reacting to light. Vision in the left eye was reduced to perception of light only. Vision in right eye was 6/6. On Ophthalmoscopy there were typical signs of central retinal artery occlusion in left eye. There was no fragmentation of blood columns in retinal vessels. No cilioretinal artery was detected. Her blood pressure was 125/85 mm. Hg. Other systems revealed no abnormality.
As the patient came alone, no retrobulbar injection could be given nor could she be admitted. However, she was advised immediate admission and the following treatment was prescribed :-
Bradilan (Nicofuranose, a vasodilator) tabs. T.D.S., Ledermycin 300 mg. 1 cap B.D. for 6 days, Cibitina (Vit B & C) 1 tab B.D.
Next day she was admitted and immediately she was given a retrobulbar injection of Duvadilan (Isoxsuprine HC1) 10 mgm in left eye, which was repeated every alternate day. A total of 7 injections were given. During this period Bradilan, Ledermycin (upto 6 days) and Cibitina were continued and Decauron 1 tab T.D.S. started and continued for I week, then gradually withdrawn.
Investigations were noncontributory except Mantoux in 100,000 was one plus (12mm indurtion). She was given a course of antitubercular treatment with I.N.H. 300 mgm and P.A.S. 12 grams daily for 1 month. Injection of neurobion (Vit. 131, B6, B12) 3cc. I.M. given on alternate days for 10 days.
From the third day her vision gradually improved to 6/18. Her visual field slightly enlarged. Left disc was pale, left macula showed slight depigmentaEion, which is commonly seen after a healed case of retinal oedema. Calibres of blood vessels were little enlarged, but still narrower and presently showing sheathing.
She was followed up every week for 2 months, then every fortnight till 3 months. Her vision and field in left eye did not show any further improvement nor any deterioration. Bradilan was withdrawn gradually after two months.
| Summary | | |
A case of central retinal artery occlusion is presented. The patient regained useful central vision even after the lapse of 26 hours before any treatment could be started[4].
