Purpose: To examine the effect of combined blepharoplasty and Müller muscle-conjunctival resection (MMCR) compared to an upper blepharoplasty on dry eye syndrome.
Design: Prospective, comparative clinical study.
Methods: This is prospective, comparative case series. Two groups of patients participated in this study: the blepharoplasty group included adult patients with dermatochalasis and the ptosis group consisted of adult patients with dermatochalasis and ptosis that showed significant improvement after phenylephrine 10% instillation. The following parameters were compared for all patients before the procedure (baseline) and on postoperative day 90: MRD1, Ocular-Surface-Disease-Index (OSDI), Schirmer test 2, tear break-up time (TBUT), fluorescein staining, Lissamine-green staining (LG).
Results: Fifty-four patients participated in this study (blepharoplasty group: 23 patients, ptosis group 31 patients). There were significant increases in the postoperative LG scores and in fluorescein staining post ptosis surgery compared with the preoperative values (paired t test, P = .05 and P = .02, respectively). The postoperative OSDI score was significantly higher post ptosis surgery compared with the preoperative score (25.38 vs 17.24, respectively, paired t test, P < .01). There were no significant differences, in the blepharoplasty group, between the postoperative and preoperative objective and subjective dry eye tests.
Conclusions: MMCR surgery causes an increase in the subjective feeling of dry eye as well as an increase of signs of dry eye. This increase was not noticed after blepharoplasty surgery. Physicians should be aware of the risk of dry eye after ptosis surgery and discuss dry eye as a complication of MMCR surgery with their patients before surgery. Those patients should be examined carefully and treated for dry eye during follow-up.

Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.

Background: Cystic fibrosis (CF) is caused by variants in a gene that encodes a protein essential for water and ion transport in the epithelial cells of exocrine organs. Given the possible relationship of this protein and conjunctival and corneal epithelium, the aim of this study was to evaluate ophthalmologic alterations in people with CF.
Methods: Forty-five people with CF underwent pulmonary evaluation including inflammatory score (IS).

Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver, with no evidence of lymphomatous involvement in other organs. Here, we report a case of diffuse large B-cell lymphoma (DLBCL)-type PHL in a patient with a long history of primary biliary cholangitis (PBC) and Sjögren's syndrome (SS). A 78-year-old woman presented with epigastralgia and was found to have a solitary liver tumor by contrast-enhanced computed tomography (CT).

Background: The ocular surface is directly exposed to environmental influences. Noxae that have already been identified for the ocular surface are heat, air dryness, pollutant gases, fine dust particles and ultraviolet radiation.
Methods: The current literature was used to investigate the relationship between frequent ocular surface diseases and various environmental factors and to analyze their development over the years.

Purpose: In the aging retina, persistent activation of microglia is known to play a key role in retinal degenerative diseases like age-related macular degeneration (AMD). Furthermore, dysregulation of the alternative complement pathway is generally accepted as the main driver for AMD disease progression and microglia are important producers of local complement and are equipped with complement receptors themselves. Here, we investigate the involvement of anaphylatoxin signaling, predominantly on Iba1+ cell activity, in light-induced retinal degeneration as a model for dry AMD, using anaphylatoxin receptor knockout (KO) mice.
