SPOTLIGHT

New Case:

Pembrolizumab (Keytruda®) Induced Uveitis in a Patient with Metastatic Melanoma:  65-year-old male with history of metastatic cutaneous melanoma previously on pembrolizuamb presented to the comprehensive ophthalmology service with blurred vision worse in the left eye for the past 6 months.

Internuclear Ophthalmoplegia: 40-year-old man presented to the emergency room complaining of acute onset blurry vision through his left eye (OS).

Fabry disease: 57-year-old Caucasian female with known history of heterozygous Fabry disease diagnosed in 2005, initially presented asymptomatically at the age of 46 with bilateral corneal verticillata, early cataracts, and vascular tortuosity.

New Atlas:

Downbeat Nystagmus: Downbeat nystagmus (DBN) is characterized by a pathologic upward drift of gaze followed by a corrective downward saccade.

Noncalcified Astrocytic Hamartoma in the setting of Retinitis Pigmentosa: Patient with a history of autosomal recessive retinitis pigmentosa (RP) presented with an amelanotic juxtapapillary retinal lesion consistent with noncalcified astrocytic hamartoma of the left eye.

Severe Proliferative Diabetic Retinopathy: 32-year-old female with poorly controlled type I diabetes mellitus and severe proliferative diabetic retinopathy.

New Tutorial:

Benign Lesions of the External Periocular Tissues: Part of the complete ophthalmic examination includes inspection of the eyelids and lashes. Anatomically, the eyelids are bordered superiorly by the eyebrow and inferiorly by the cheek. The majority of this area is covered superficially by a keratinizing stratified squamous epithelium. Because of this, the eyelid is prone to many of the same dermatologic lesions found elsewhere on the skin covered areas of the body.

Malignant Lesions of the External Periocular Tissues: A thorough ophthalmic examination should always include careful inspection of the external periocular tissues. These tissues include specialized structures that are prone to unique pathology. For example, the eyelid has cilia, sebaceous glands of Zeis, apocrine sweat glands of Moll, eccrine sweat glands, and vellus hairs.

Iris Prolapse: The History of this Ancient (and Present) Surgical Challenge: This article will discuss the history and mechanical theories explaining iris prolapse and an accompanying tutorial will propose ten tips to prevent and treat iris prolapse. Narrated surgical videos will be used to demonstrate these key principles.

Ten Tips to Prevent and Treat Iris Prolapse: This tutorial will propose ten tips to prevent and treat iris prolapse. An accompanying article will discuss the history of iris prolapse as well as several mechanical and fluid dynamics-based theories believed to contribute to iris prolapse.
