Fuchs' heterochromic iridocyclitis is an atypical form of chronic nongranulomatous anterior uveitis and is almost always unilateral. It presents with cataract, mild anterior chamber reaction, diffuse stellate keratic precipitates, absence of posterior synechiae, iris hypochromia and glaucoma. It is usually bilateral but may be asymmetrical. Unilateral megalocornea has been reported in a case of lamellar icthyosis. Slit lamp evaluation of right eye of a 70 year old revealed diffusely distributed fine, stellate white keratic precipitates, mild anterior chamber reaction and hypermature morgagnian cataract. Examination also revealed large cornea in right eye with normal pachymetry and keratometry values.

| Introduction|| |
Fuchs' heterochromic iridocyclitis is an atypical form of chronic nongranulomatous anterior uveitis and is almost always unilateral. It accounts for 1%–6% of all uveitis. It presents with cataract, mild anterior chamber reaction, diffuse stellate keratic precipitates, absence of posterior synechiae, iris hypochromia, and glaucoma. Megalocornea is an uncommon congenital anomaly, in which the entire anterior segment is abnormally enlarged. Cataract is a well-known association. It is usually bilateral, but may be asymmetrical. Unilateral megalocornea has been reported in a case of lamellar ichthyosis.
| Case Report|| |
A 70-year-old male presented with a gradual loss of vision in the right eye (RE) for 2 years. Ocular examination revealed visual acuity of hand movements in the RE. RE showed large cornea with diameter of 15 mm horizontally and 14.5 mm vertically [Figure 1]. Slit-lamp evaluation of the RE revealed diffusely distributed fine, stellate white keratic precipitates; mild anterior chamber reaction; and hypermature morgagnian cataract [Figure 1]. Intraocular pressure was 27 mmHg. Keratometry values were as follows: for RE, K1 = 42.50 and K2 = 43.25 and for left eye (LE), K1 = 43.25 and K2 = 43.75. Pachymetry values were 525 μ in the RE and 520 μ in the LE. Examination of the LE was essentially normal.

| Conclusion|| |
The case is highlighted for unilateral presentation of megalocornea. This is a previously unrecorded association and the first report of Fuchs' heterochromic iridocyclitis in a patient with unilateral megalocornea.
