Intralenticular neovascularization in a cataractous crystalline lens. 白内障晶体晶状体内新生血管的形成。

Neovascularization results secondary to hypoxic conditions within the eye. A natural balance of angiogenic and antiangiogenic factors are critical for the eye to prevent the formation of neovascularization. Various factors can upset this natural balance, resulting in angiogenesis. Due to the lack of an intrinsic blood supply, intralenticular neovascularization is rare.</p><p><strong>Case report: </strong>A 61-year-old black male presented with a previous diagnosis of proliferative diabetic retinopathy (PDR).

Dry-eye--is inflammation just the tip of the iceberg? 干眼症——炎症只是冰山一角吗?

{"title":"Dry-eye--is inflammation just the tip of the iceberg?","authors":"Edward S Jarka, Mark Kahrhoff, John B Crane","doi":"","DOIUrl":"","url":null,"abstract":"<p><strong>Background: </strong>Dry eye syndrome (DES) has been described by The International Dry Eye WorkShop as ''multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tear instability with potential damage to the ocular surface.'' Inflammation has been recognized as a primary contributor to the disease and was a tremendous step forward in the description and treatment of DES. Although most treatments of DES treat inflammation, the signs and symptoms of DES usually return shortly after discontinuing the use of the anti-inflammatory agent;</p><p><strong>Case: </strong>We present a case of a 70-year-old patient who presents with significant dry eye symptoms for 2 years. She reports the need to wear sunglasses during all waking hours, both indoors and out, and had discontinued her hobby of gardening. She had ocular rosacea diagnosed at a previous ophthalmology practice and did not respond to any past treatments.

A comparision of short and long reading passages in symptomatic vs. asymptomatic subjects. 有症状和无症状受试者的短文和长文阅读比较。

{"title":"A comparision of short and long reading passages in symptomatic vs. asymptomatic subjects.","authors":"Dustin Dixon, Marc B Taub, Richard Hoenes, W C Maples","doi":"","DOIUrl":"","url":null,"abstract":"<p><strong>Background: </strong>The visual system is necessary for reading. Understanding the mechanics of eye movements during reading can give insight into the reading process. The ReadAlyzer is an electronic recording system that measures eye movements while reading. Long passages on the ReadAlyzer of 800 words have recently been introduced as a tool to assess the efficiency of reading eye movements. Previously, short passages of 100 words have been used exclusively. This project was designed to determine if passage length influences the quality of reading eye movements;</p><p><strong>Methods: </strong>Optometry students (N = 40) at Southern College of Optometry were separated into 2 equal groups (symptomatic vs. asymptomatic) based on the College of Optometrists in Vision Development Quality of Life questionnaire score. Each subject then performed two reading passage recordings with the ReadAlyzer: one short, one long. The order of the passages was alternated to reduce fatigue effects. Data were collected based on the ratio of fixations-to-regressions;</p><p><strong>Results: </strong>A multivariate analysis of variance indicated that the difference between short and long paragraphs for the symptomatic and asymptomatic groups combined was significant (P = 0.001) but was not significant for the symptomatic group vs. the asymptomatic group ( P = 0. 651) . Post-hoc comparisons using estimated marginal means indicated for asymptomatic, short vs. long, P = .036 and for symptomatic, short vs. long, P = 0.008. Additionally, for short length, symptomatic vs. asymptomatic, P = 0.242 and for long length, symptomatic vs. asymptomatic, P = 0.176;</p><p><strong>Conclusion: </strong>This information indicates that both symptomatic and asymptomatic patients will have more difficulty on longer reading passages.
