Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of pressure patching versus no patching for corneal abrasions due to trauma or foreign body removal. Corneal Abrasion Patching Study Group.
To evaluate the effectiveness of pressure patching in the treatment of noninfected, noncontact lens-related traumatic corneal abrasions and abrasions secondary to removal of corneal foreign bodies. ⋯ Noninfected, noncontact lens-related traumatic corneal abrasions as well as abrasions secondary to foreign body removal can be treated with antibiotic ointment and mydriatics alone without the need for a pressure patch.

Randomized Controlled Trial Clinical Trial
A prospective, randomized, double-masked trial to evaluate the role of topical anesthetics in controlling pain after photorefractive keratectomy.
To investigate the role of 1% tetracaine in controlling pain after photo-refractive keratectomy (PRK) and determining its effect, if any, on epithelial healing, refractive outcome, and visual performance. ⋯ Tetracaine in conjunction with coproxamol is effective in reducing pain after PRK without adversely affecting corneal wound healing or visual performance.

Comparative Study
Ocular adnexal lymphoma. A clinicopathologic study with identification of lymphomas of mucosa-associated lymphoid tissue type.
Extranodal marginal zone B-cell lymphoma (low-grade B-cell lymphoma of mucosa-associated lymphoid tissue [MALT] type) is a distinctive type of lymphoma that usually arises in association with mucosa or other epithelial structures and has an indolent clinical course. The frequency and clinical features of MALT lymphomas in the ocular adnexa have not been well studied. ⋯ Ocular adnexal lymphomas are B-cell tumors that develop in older adults, predominantly among women. Primary orbital lymphomas have a favorable prognosis; a high proportion of them have MALT characteristics.
