Peripheral ulcerative keratitis secondary to severe hidradenitis suppurativa.

Purpose: To describe a unique case of peripheral ulcerative keratitis secondary to isolated, severe hidradenitis suppurativa (HS).

Observation: A 31-year-old male with HS presented with a red painful right eye with best corrected visual acuity of count fingers at 3 feet with peripheral corneal thinning, inferior descemetocele, and adjacent infiltrate. Work-up revealed negative corneal cultures and positive ANA, ANCA, and rheumatoid factor without other autoimmune or rheumatologic history or symptomatology.

Primary Nasolacrimal Duct Obstruction Visualized on I Preablation Scan for Papillary Thyroid Carcinoma.

A 56-y-old man underwent total thyroidectomy and bilateral central and right lateral neck dissection for papillary thyroid carcinoma with lymph nodes metastases. Before radioiodine ablation, a I scan established the diagnosis of primary nasolacrimal duct obstruction (dacryostenosis).

The Effects of Glaucoma Drainage Devices on Oxygen Tension, Glycolytic Metabolites, and Metabolomics Profile of Aqueous Humor in the Rabbit.

Purpose: Glaucoma drainage device (GDD) implantation can lead to corneal decompensation. We evaluated changes over time in oxygen tension and in the metabolic environment of the aqueous humor after GDD implantation in the rabbit eye.

Methods: Ahmed Glaucoma Valves were implanted in the left eyes of eight male New Zealand white rabbits.
