Comparative StudyHigh-volume intraocular lens surgery in a rural eye camp in India.
The appropriate surgical treatment for the enormous number of patients in developing nations who are blind due to cataract is a hotly debated issue. The authors objective is to demonstrate that modern surgical techniques (extracapsular cataract extraction and intraocular lens implantation, phacoemulsification and intraocular lens implantation) can be performed in a high-volume, cost effective manner, even in temporary settings. The authors believe that the approach to cataract blindness is not simple intracapsular cataract extraction, but rather the challenge of (1) training all ophthalmic personnel in modern techniques (microsurgery, biometry), (2) training managers in higher levels of organizational skill, and (3) doing these things in the face of limited resources. ⋯ For this type of camp to operate efficiently, there must be standardization of skills among ophthalmic personnel, costs must be contained, and the organizational skills necessary to ensure smooth functioning of the camp must exist. However, on the basis of their data, these authors believe that with suitable organizational and surgical facilities, IOL implantation can be successfully performed in high-volume surgical eye camps.

Case ReportsCluster headache presenting with orbital inflammation.
Acute, noninfectious orbital inflammations often defy a specific diagnosis despite a thorough medical evaluation and are grouped in the nonspecific diagnostic category of idiopathic inflammation of the orbit (pseudotumor). An atypical case of cluster headache presenting with intermittent migratory facial swelling and orbital inflammation, and 3 mm of exophthalmos simulating idiopathic orbital inflammation is presented. ⋯ After unsuccessful treatment directed at potential infectious and inflammatory causes, the patient responded well to methysergide, an established treatment for cluster headaches. A review of the known mechanism for this disorder, peripheral and central nervous system mechanisms of pain, and migratory angioedema reveals overlapping pathophysiology, clinical findings, and associated symptoms.
