Immune responses to injury and their links to eye disease.

Transl Res 2021 May 27. Epub 2021 May 27.

Department of Pathology, Anatomy and Cell Biology, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania; Department of Ophthalmology, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania.

The eye is regarded as an immune privileged site. Since the presence of a vasculature would impair vision, the vasculature of the eye is located outside of the central light path. As a result, many regions of the eye evolved mechanisms to deliver immune cells to sites of dysgenesis, injury, or in response to the many age-related pathologies. Read More

Acute transient macular detachment after uneventful cataract surgery in a highly myopic eye.

Am J Ophthalmol Case Rep 2021 Jun 6;22:101117. Epub 2021 May 6.

Institute of Ophthalmology, University of Modena and Reggio Emilia, Modena, Italy.

Purpose: We report a case of a highly myopic patient who presented a serous macular detachment at 24 hours after uncomplicated cataract surgery.

Observations: Surprisingly, after six days from surgery, a reabsorption of the detachment was noticed and the macular area returned to be anatomically normal without any surgical intervention. This early postoperative complication could be caused by changes in the vitreoretinal interface and ocular fluid dynamics or to a rupture of blood-retinal barriers due to postoperative inflammation.

Inspection of the lens thickness with preoperative biometric measurements prevents an erroneous interpretation of posterior capsule during FLACS.

Sci Rep 2021 May 6;11(1):9702. Epub 2021 May 6.

Department of Ophthalmology, The Jikei University School of Medicine, Tokyo, Japan.

Optical opacity reduces quality of biometry images, making it potentially difficult to find the correct location for irradiation during femtosecond laser-assisted cataract surgery (FLACS). After experiencing a case of posterior capsule (PC) rupture because of optical opacity, we started lens thickness (LT) inspection, which indicates comparison of between intra- and pre-operatively measured LT. We retrospectively investigated the effectiveness of the LT inspection. Read More

Cataract-causing allele in CRYAA (Y118D) proceeds through endoplasmic reticulum stress in mouse model.

Zool Res 2021 May;42(3):300-309

Eye Center of the Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang 310009, China.

As small heat shock proteins, α-crystallins function as molecular chaperones and inhibit the misfolding and aggregation of β/γ-crystallins. Genetic mutations of are associated with protein aggregation and cataract occurrence. One possible process underlying cataract formation is that endoplasmic reticulum stress (ERS) induces the unfolded protein response (UPR), leading to apoptosis. Read More

Department of Ophthalmology, The First Affiliated Hospital of Gannan Medical University, Ganzhou, Jiangxi 341000, P.R.China.

The existing retinal vessels segmentation algorithms have various problems that the end of main vessels are easy to break, and the central macula and the optic disc boundary are likely to be mistakenly segmented. To solve the above problems, a novel retinal vessels segmentation algorithm is proposed in this paper. The algorithm merged together vessels contour information and conditional generative adversarial nets. Read More

Organelle degradation in the lens by PLAAT phospholipases.

Nature 2021 Apr 14;592(7855):634-638. Epub 2021 Apr 14.

Department of Biochemistry and Molecular Biology, Graduate School and Faculty of Medicine, The University of Tokyo, Tokyo, Japan.

The eye lens of vertebrates is composed of fibre cells in which all membrane-bound organelles undergo degradation during terminal differentiation to form an organelle-free zone. The mechanism that underlies this large-scale organelle degradation remains largely unknown, although it has previously been shown to be independent of macroautophagy. Here we report that phospholipases in the PLAAT (phospholipase A/acyltransferase, also known as HRASLS) family-Plaat1 (also known as Hrasls) in zebrafish and PLAAT3 (also known as HRASLS3, PLA2G16, H-rev107 or AdPLA) in mice-are essential for the degradation of lens organelles such as mitochondria, the endoplasmic reticulum and lysosomes.

Intra-operative control of positive vitreous pressure in a graded manner by pars plana sutureless, small gauge trocar-cannula.

Eur J Ophthalmol 2021 Apr 15:11206721211009446. Epub 2021 Apr 15.

Department of Ophthalmology, Shri Jagdamba Charitable Eye Hospital, Sri Ganganagar, Rajasthan, India.

Background: The purpose of this paper is to delineate a technique of using a 23G, single, sutureless transconjunctival pars plana sclerotomy to facilitate anterior segment surgery in eyes with increased positive vitreous pressure (PVP) ascribe to predisposing or intraoperative factors.

Methods: We have implemented this technique in five eyes when PVP was anticipated before the surgery because of risk factors or it was encountered during anterior segment surgery. Different case scenarios in which PVP occurs during the surgery comprising phacolytic glaucoma, corneal tear repair combined with cataract surgery with IOL in a case with traumatic corneal injury, anterior capsule rupture and secondary glaucoma, Trabeculectomy in case of uveitic glaucoma, routine phacoemulsification cataract surgery with PVP encountered during surgery were addressed by using this technique.

Amine oxidase copper-containing 3 (AOC3) inhibition: a potential novel target for the management of diabetic retinopathy.

Int J Retina Vitreous 2021 Apr 12;7(1):30. Epub 2021 Apr 12.

Byers Eye Institute, Stanford University, Palo Alto, CA, USA.

Background: Diabetic retinopathy (DR), a microvascular complication of diabetes, is the leading cause of visual impairment in people aged 20-65 years and can go undetected until vision is irreversibly lost. There is a need for treatments for non-proliferative diabetic retinopathy (NPDR) which, in comparison with current intravitreal (IVT) injections, offer an improved risk-benefit ratio and are suitable for the treatment of early stages of disease, during which there is no major visual impairment. Efficacious systemic therapy for NPDR, including oral treatment, would be an important and convenient therapeutic approach for patients and physicians and would reduce treatment burden. Read More

Semibrittle seismic deformation in high-temperature mantle mylonite shear zone along the Romanche transform fault.

Sci Adv 2021 Apr 9;7(15). Epub 2021 Apr 9.

Università di Modena e Reggio Emilia, Modena, Italy.

Oceanic transform faults, a key element of plate tectonics, represent the first-order discontinuities along mid-ocean ridges, host large earthquakes, and induce extreme thermal gradients in lithosphere. However, the thermal structure along transform faults and its effects on earthquake generation are poorly understood. Here we report the presence of a 10- to 15-kilometer-thick in-depth band of microseismicity in 10 to 34 kilometer depth range associated with a high-temperature (700° to 900°C) mantle below the brittle lithosphere along the Romanche mega transform fault in the equatorial Atlantic Ocean.

Division of Plastic Reconstruction, Department of Ear, Nose and Throat, Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia.

Introduction: Ophthalmic trauma is defined as injuries affecting the ocular structures, including the globe, eyelid, lacrimal system, and surrounding orbital walls. Blunt trauma acts as the leading cause of injury and it may affect both the anterior and posterior parts of the globe. Prompt diagnosis, early management, and sustained follow-up are mandatory for an optimal outcome. Read More

The Latest Evidence with Regards to Femtosecond Laser-Assisted Cataract Surgery and Its Use Post 2020.

Clin Ophthalmol 2021 30;15:1357-1363. Epub 2021 Mar 30.

Vision Eye Institute, Hawthorn East, VIC, Australia.

Femtosecond laser-assisted cataract surgery (FLACS) was introduced with the hope of making cataract surgery safer and making the refractive result more predictable. It is only in the last four years that level 1 prospective randomised controlled trials (RCT) using current technology have been published. These, along with a meta-analysis of recent studies have shown that there seems to be little long-term visual benefit when using FLACS with monofocal lenses. Read More
