Corneal Edema Associated With Degenerating Soemmering Ring Cataract: Clinical-Pathologic Correlation, Jordan P Safran, Nathan Nataneli, Jayesh Vazirani, Ralph C. Eagle Jr, Tatyana Milman

Wills Eye Hospital Papers

Purpose: To report three patients with an uncommon delayed complication of cataract extraction: corneal edema following dispersion of calcific lens particles from a degenerating Soemmering ring cataract.

Observations: We report three patients, 75-92 years old, presenting with corneal edema and dispersed, degenerated calcific lens material in the anterior chamber and vitreous 20-30 years after cataract surgery. In all patients, calcific particles studded the posterior surface of the cornea in a gravity-dependent distribution without apparent inflammation and were associated with localized corneal edema. In one patient, calcific particles were also associated with secondary open angle glaucoma. Deposits originated from the calcified …

In Vivo Determination Of The Human Corneal Elastic Modulus Using Vibrational Optical Coherence Tomography, Marcos A. Crespo, Hiram J. Jimenez, Tanmay Deshmukh, Jose S. Pulido, Ahmed Saeed Saad, Frederick H Silver, Dominick A Benedetto, Christopher J Rapuano, Zeba Syed

Purpose: To determine the in vivo elastic modulus of the human cornea using vibrational optical coherence tomography (VOCT).

Methods: Vibrational analysis coupled with optical coherence tomography (OCT) was used to obtain the resonant frequency (RF) and elastic modulus of corneal structural components. VOCT corneal thickness values were measured using OCT images and correlated with corneal thickness determined with Pentacam (Oculus, Wetzlar, Germany). Moduli were obtained at two locations: central cornea (CC) and inferior cornea (IC). Measurements were obtained with and without anesthetic eye drops to assess their effect on the modulus measurements.

Results: VOCT thickness values correlated positively (R2 = …

Ocular Adnexal Metastases From Renal Cell Carcinoma: An Update And Comprehensive Literature Review, Tejal Magan, Tejus Pradeep, Madalina Tuluc, Jurij R. Bilyk, Tatyana Milman

PURPOSE: The purpose of this study was to review the clinical presentation, systemic work-up, and outcomes of all previously reported ocular adnexal (OA) metastases from renal cell carcinoma (RCC). METHODS: This was a literature review. PubMed and Google Scholar databases were searched for all well-documented cases of OA metastases from RCC. RESULTS: Final analysis identified 44 patients with either biopsy-confirmed (41/44, 93%) or treatment response-documented (3/44, 6%) OA metastases from RCC. Thirty-four (77%) patients were male. The median age was 60 years (mean: 60, range: 22-87 years). The most common presenting signs were proptosis (19/44, 43%) and OA mass (14/44, …
