Translacrimal transnasal laser-assisted dacryocystorhinostomy.

Chronic dacryocystitis is due to an obstruction in the nasolacrimal duct, with subsequent infection of the lacrimal sac. The goal of surgery is to reestablish intranasal drainage of the lacrimal sac. Classic dacryocystorhinostomy (DCR) requires an external incision and drilling through the lacrimal bone into the middle meatus.

Use of the Shaw scalpel in ophthalmic surgery.

A resistively heated scalpel (Shaw scalpel) was used in ten patients for orbital and lid surgical procedures. The blade temperature is set from 110 degrees to 270 degrees C producing a remarkable hemostatic effect with minimal thermal damage to the incision margins. The instrument has proven useful in preserving a good view of the anatomy during dissection and specifically it simplifies excision of orbital fat in blepharoplasty and orbital decompressions for Graves' orbitopathy.

Ocular toxocariasis presenting as leukocoria in a patient with low ELISA titer to Toxocara canis.

A 4-year-old white female presented with leukocoria of the right eye. White punctate lesions were observed posterior to the retrolental membrane, which suggested retinoblastoma of some examiners. A full history, physical examination, ultrasonography, and CT scan failed to rule the diagnosis of retinoblastoma in or out.

Posterior ocular abnormalities after irradiation for retinoblastoma: a histopathological study.

Radiation-induced ocular lesions in the posterior eye and orbit were investigated in 33 surgical specimens of patients with retinoblastoma. The eyes were obtained from children 7 months to 6 years of age. Seventeen eyes were irradiated; 16 eyes had not received irradiation and served as controls.

Rubeosis iridis in "pseudogliomas".

A total of 85 eyes (75 patients) with pseudogliomas (i.e., certain conditions which simulate retinoblastoma, were examined histopathologically to determine the incidence of rubeosis iridis.
