A 35 year old male, otherwise asymptomatic presented for some travel induced irritation of his eyes.
his 6/6 vision in both eyes;
but
cupping of 0.8 in RE and 0.9 in LE, NRR thin but no notching. No obvious nerve fibre defect seen.
IOP 14 mm applanation in both eyes;
normal fields both eyes.
Gonio open in all quadrants.
No history whatsoever suggestive of intermittant angle closure.
In other words, all parameters except disc are normal.
He had been seen 3 years ago at Tadepalligudem, and apparently his condition was exactly the same even then including vision and fields.
Any explanation for this isolated disc picture, a rather alarming but apparently innocuous cupping with no other supporting symptoms/ signs of glaucoma?
