RAF near point rule for near point of convergence—a short review

:-
 

Abstract: RAF near point rule (RNPR) is a routinely used instrument in ophthalmology and optometry practice as well as for research purposes to measure the near point of convergence (NPC). The measurement of NPC is an important criterion for diagnosis and management of convergence insufficiency. The RNPR forms an important tool for ophthalmic clinicians however, only a very little is understood about it. This article tries to describe and review the designs, measurement techniques, merits and demerits of the RNPR and establish the need for its modification. It recommends that clinicians and researchers consider these findings while measuring NPC with the RNPR.

Tweaking the immune system as an adjuvant for the treatment of retinal degenerations

:-
 

Abstract: Blinding diseases such as photoreceptor degenerations are debilitating conditions that severely impair daily lives of affected patients. This group of diseases are amenable to photoreceptor replacement therapies and recent transplantation studies provided proof-of-principle for functional recovery at the retinal and behavioral level, though the actual mechanism of repair still needs further investigations. The immune system responds in several ways upon photoreceptor engraftment, resulting in T-cell and macrophage infiltrations and, consequently, decrease in graft survival. Most studies on the role of the immune system suggest a detrimental effect in a therapeutic setting. Conversely, the opposite idea wherein the immune system can be activated towards a protective state was also explored in other experimental paradigms. Here, Neves and colleagues explored the potential of cross-species studies and, to a certain extent, the concept of a protective immune system in retinal degeneration and therapy. Mesencephalic astrocyte-derived neurotrophic factor (MANF) was identified in this study as a novel factor that, by modulating the immune system, can slow down photoreceptor degeneration and improve transplantation outcome.

The use of aflibercept in ophthalmology: a review of randomized controlled trials

:-
 

Abstract: We reviewed randomized controlled trials associated with the intravitreal use of aflibercept for this article. These studies proved that aflibercept is an effective anti-vascular endothelial growth factor agent for the treatment of neovascular age-related macular degeneration (nAMD), myopic choroidal neovascularization (mCNV), diabetic macular edema (DME), and macular edema associated with retinal vein occlusion. The incidence of severe ocular or systemic complications after intravitreal administration of aflibercept was low.

Clear lens extraction as the first line treatment of primary angle closure/primary angle closure glaucoma

:-
 

Abstract: Angle closure glaucoma (ACG) is one of the major causes of blindness. Angle closure occurs from the obstruction of the trabecular meshwork by the peripheral iris, which results in increased intraocular pressure (IOP) through impaired aqueous flow. Considering pupillary block by crystalline lens is the most frequent mechanism, lens extraction is regarded as an effective therapy. Recently, to validate the effect of lens extraction, the EAGLE study was reported. In this study, subjects were 50 years or older, did not have cataracts, and had newly diagnosed primary angle closure (PAC) with intraocular pressure 30 mmHg or greater or primary angle-closure glaucoma (PACG), and were divided into clear-lens extraction group and standard care group (laser peripheral iridotomy and topical glaucoma medication). This study suggested that clear-lens extraction showed greater efficacy and was more cost-effective than laser peripheral iridotomy. Initial clear lens extraction showed better clinical course and patient-reported outcomes. This study provided evidence to support clear lens extraction as the first line treatment for PAC with high IOP or PACG patients.
