Sensitivity of Computed Tomography for the Assessment of Spontaneous Dermoid Cyst Localized Rupture with Granulomatous Reaction.

Purpose: To assess the sensitivity of computed tomography for the diagnosis of spontaneous localized orbital dermoid cyst rupture with granulomatous reaction.

Methods: The charts of 42 patients with dermoid cysts were reviewed retrospectively. The data collected included demographics, clinical features, CT imaging, and postoperative histopathological analysis of the lesions.

Dacryoliths causing intermittent epiphora associated with a patent lacrimal system.

We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fungal colonization formation may be the first event before dacryocystitis and should be considered as a cause of epiphora.

Hyperostosis Following Orbital Exenteration.

Purpose: To describe CT scan findings following orbital exenteration in 27 patients and to identify the factors involved in the development of post exenteration hyperostosis.

Methods: Noncomparative case series. The authors reviewed the charts of 27 patients ranging in age from 33 to 99 years, who underwent unilateral exenteration at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia and at the School of Medicine of Ribeirão Preto, University of São Paulo, Brazil.

Accessory lacrimal gland duct cyst: 23 years of experience in the Saudi population.

Background And Objectives: Accessory lacrimal gland ductal cyst is a rare clinical entity that has been reported after trauma, infection, or conjunctival inflammation. Trachoma has been postulated as an etiologic factor for this dacryops in Saudis. We studied the prevalence, demographics, clinicopathological features and surgical approach for these lesions.

Iris color: validation of a new classification and distribution in a Spanish population-based sample.

Purpose: To design and validate a standard, simple, and reliable iris color classification and to study its distribution in a Spanish population. Iris color has a geographic distribution and has been correlated with different ocular diseases. However, there is no standard and validated iris color classification allowing comparison among different studies.
