Ocular Tuberculosis with Progressive Unilateral Corneal Melting

OBJECTIVES In this case report, we present a patient with ocular tuberculosis presenting with progressive unilateral corneal melting. PATIENT A 47-year-old female was admitted with melting at the inferior half of the peripheral cornea and inferior subconjunctival nodules. Biopsy material of the nodules was negative for tuberculosis bacillus. However, polymerase chain reaction of the biopsy sa...

Missed punctal foreign body: A cause for chronic ocular irritation

Case 1 A 48‐year‐old male, financial advisor by occupation, presented with swelling of eyelids, redness, foreign body (FB) sensation, and watering of the right eye for 2 weeks. He gave history of consulting two ophthalmologists but did not get relief. There was no history of any trauma or surgery.

Phacoemulsification in eyes with corneal opacification.

We describe a technique in which transcorneal illumination with a fiber-optic light probe is used to safely perform phacoemulsification in cataractous eyes with dense corneal opacification. The technique was used in 3 eyes of 3 patients. No surgical complications occurred, and all eyes had improved visual acuity. Indications and further refinement of the technique and instrumentation are discus...

An in Vitro Evaluation Method to Test Ocular Irritation using a Human Corneal Epithelium Model

Recently, safety evaluation tests that do not involve animal experiments have been prosperously developing. However, the optimal evaluation materials and methods for assessing ocular irritancy have not been well investigated. In this study, we determined the optimal evaluation method for testing ocular irritation using a human cultured corneal epithelium model (corneal model). In order to asses...
