Inflammatory Granulomatous Corneal Disease: Ocular Granuloma Annulare.

Granuloma annulare is a well-known skin disease characterised by small papules arranged in a ring around a lesion with a normal atrophic centre. It may have variable clinical presentations and associations. Herein, we describe its novel ocular association with inflammatory granulomatous corneal disease (IGCD). It was observed in a young patient diagnosed with granuloma annulare. His symptoms included blurring of vision associated with photophobia in both eyes. There was marked stromal oedema with corneal haze at variable depths and mild anterior chamber flare. It resolved completely with topical steroids. This case discusses a unique manifestation of multisystemic IGCD with granuloma annulare that may co-exist with skin lesions. To the best of our knowledge, this unique entity has not been described in the literature previously.

Bilateral post-LASIK exacerbation of granular corneal dystrophy with epithelial ingrowth.

A male patient in his 30s, with a history of bilateral microkeratome-assisted myopic laser-assisted in situ keratomileusis (LASIK) 8 years ago at another centre, presented to us with gradually progressive diminution of vision and glare in both eyes for the last 4 years. On presentation, uncorrected distance visual acuity (UDVA) was 6/24 and 6/15 in the right eye and left eye, respectively, with normal intraocular pressures. Slit-lamp examination and anterior segment optical coherence tomography revealed well-defined white deposits, limited to an area within the LASIK flap. The deposits were confluent, at the level of the LASIK flap interface, and few discrete opacities were present in the posterior stroma. His father also had a similar clinical picture in both eyes. A diagnosis of both eyes post-LASIK exacerbation of granular corneal dystrophy with epithelial ingrowth was made. He underwent right eye femtosecond laser-assisted sutureless superficial anterior lamellar keratoplasty. At 6-month follow-up, UDVA improved to 6/12 with graft clarity of 4+ and coexistent grade 1 epithelial ingrowth.

Intracameral vent and flush technique for silicone oil blockade in Ahmed glaucoma valve.

The presence of emulsified silicone oil in the eye can lead to many complications, glaucoma being one of the most common. Adequate IOP control is difficult to achieve with medical management alone; surgical intervention is often required. Glaucoma drainage device implantation is often the preferred line of surgical intervention in such cases due to trabeculectomy failure from emulsified silicone oil droplets and associated conjunctival scarring. However, the silicone tube of Ahmed glaucoma valve (AGV) may attract the silicone oil droplets, causing blockade of the tube with persistent raised IOP postoperatively. We report one such case where post-AGV silicone oil tube occlusion was treated with semi-conservative surgical management instead of revising the entire surgery or implantation of another drainage device. Our surgical technique of intracameral "vent and flush" offers rapid and effective IOP control in such cases. Postoperatively, normal IOP was achieved. Patency of tube continued to be maintained along with normalization of IOP on subsequent follow-ups.
