Vogt is a very familiar word in ophthalmology and there are several clinical entities linked with this word. Vogt's triad is defined in glaucoma and is often related to a previous acute angle-closure attack. The triad is named after the Swiss Ophthalmologist Alfred Vogt, who first described glaucomflecken, following acute glaucoma. Interestingly, one may find the term Vogt's triad described outside ophthalmology, in tuberous sclerosis to the commonly known acronym epilepsy, low intelligence and adenoma sebaceum (EPILOA).
A 60-year-old female patient presented with sudden-onset headache and right eye pain of 3 days duration. Her right eye vision was counting fingers at 1 m, and intraocular pressure was 62 mmHg. The affected eye was congested and had corneal edema, shallow anterior chamber, mid-dilated fixed pupil, and glaucomflecken [Figure 1]. A 63-year-old female patient presented with a past history of acute angle-closure attack in the left eye 2 years ago. Left eye vision was hand movements close to face. Slit-lamp examination showed a shallow anterior chamber, mid-dilated fixed pupil, iris atrophic patches, and absence of glaucomflecken [Figure 2]. The left eye intraocular pressure was 20 mmHg with topical medications. The fundus examination revealed disk pallor with total cupping.

| Discussion|| |
The above description is about two patients who had acute primary angle-closure attack. But akin to the first patient with acute presentation, iris atrophy, which is a part of the triad, is rarely seen as it is a late feature that develops with time. However, when the patient presents at a later date with a past history of acute primary angle-closure attack, one may or may not be able to find all the features comprising the triad. The second patient though had such a past history, had no identifiable glaucomflecken, and hence no triad. The same holds true about the triad when the affected eyes are subjected to cataract surgery.
