At present, phacoemulsification and trabeculectomy are the most widespread surgery methods in cataract and glaucoma treatment, generally recognized as the gold standard. Among elderly patients, comorbid glaucoma and cataract are extremely prevalent, so the order of the two surgeries and the time interval between them are pivotal choices when planning treatment strategy. The reason for it is that almost any eye surgery is considered a risk factor for long-term trabeculectomy effectiveness. In attempts to solve this problem, numerous studies have been conducted on the impact of cataract surgery on filtration bleb scarring. The problem of determining the time interval between surgeries, as well as other treatment nuances, remains relevant despite the long history of research and publications. Some results are cited as general recommendations on treatment tactics (increasing the time interval between operations, using antimetabolite and anti-inflammatory therapy, minimizing intraoperative traumatism). However, currently there are no specific recommendations for one of the most important factors - the time interval between cataract extraction and trabeculectomy.

The main reason of surgical treatment failure in cases of chronic dacryocystitis concurrent with nasolacrimal duct obliteration is scarring of the newly created ostium. This outcome is caused by the continued activity of myofibroblasts that leads to the formation of a rough scar. Mitomycin C is currently considered to be the most preferred anti-fibrotic drug. Nonetheless, contradictory evidence of the drug efficiency stimulates further research for finding alternative anti-fibro-tic therapeutics. Recently, several advances were made in developing new anti-fibrotic drugs, including monoclonal antibodies, small RNA molecules, and other gene therapy formulations, nanoparticles and small-molecule therapeutics. This review article aims to provide up-to-date information on the efficacy of mentioned agents and on prospects of their use in dacryology.

The healing process in the adult rabbit conjunctiva and sclera tissues after translimbal microdrainage with the use of either biodegradable antiglaucomatous drainage (BDAD) or iGen was studied. Wound areas showed similar acute inflammatory response to the implantation of both matrixes on the 7th day. Complete lysis degradation of iGen and BDAD was observed on 30th day and 60th day, respectively. Within 60 - 90 days after BDAD implantation, the wound areas of conjunctiva and sclera showed intensive angiogenesis and poor extracellular matrix scarring. In contrast, on the 90th day after iGen implantation, a decrease in angiogenesis and intensive extracellular matrix scar formation were observed. As a result of scarring the thin-walled vessels were compressed, which led to the reduction of aqueous humor outflow.
