Purpose: We investigated the influence of various factors on visual results in patients undergoing surgical removal of choroidal neovascular membranes (CNVM) caused by age-related macular degeneration (AMD).
Subjects And Methods: This study was performed in 55 eyes of 55 patients who underwent surgical removal of CNVM for AMD and followed them for 6 months or more. The criterion for surgical eligibility was active subfoveal choroidal neovascular membrane of 0.5 or more disc diameter above the retinal pigment epithelium with visual acuity of 0.3 or worse. We investigated the influence of various factors on the logarithm of the minimum angle of resolution (log MAR) final visual acuity. The factors were age, symptom duration, preoperative log MAR visual acuity, CNVM diameter, mean deviation with visual field analyzer, previous laser treatment, posterior vitreous detachment, findings of indocyanine green angiography, operative complications, and recurrence of CNVM.
Results: Better preoperative visual acuity, shorter symptom duration, and smaller CNVM diameter were correlated with better postoperative final visual acuity.
Conclusions: Surgical excision of subfoveal CNVM may be the better therapeutic choice in selected cases with AMD.

Background: Dementia and visual impairment are both associated with reduced mobility and impaired functioning in activities of daily living (ADL) and instrumental activities of daily living (IADL). Cognitive deficits in older adults have more difficulties in performing daily tasks, increase the risk of fear of participation and may lead to injury (e.g.

This research was designed to evaluate the efficacy and safety of ab-interno trabeculectomy (Trabectome and Kahook Dual Blade) combined with phacoemulsification, intraocular lens implantation, and goniosynechialysis in eyes with primary angle-closure glaucoma. A total of 47 patients were included in the study and all the patients received the combined surgery. Intraocular pressure, anti-glaucoma medications, best-corrected visual acuity, and the number of peripheral anterior synechiae quadrants were recorded at baseline and at various time points after surgery.

This study aims to analyze the prevalence and severity of posterior capsule opacification (PCO) and glistening in a new hydrophobic biaspheric monofocal intraocular lens (IOLs) 24 months after implantation. By means of a ambispective, observational, case-control design, a total of 297 eyes from 200 cataract surgery patients were included in the study (118 females and 82 males; mean age: 72.31 ± 9.

Non-functioning pituitary adenomas (NFPAs) are hormonally inactive benign tumors, usually diagnosed as macro-adenoma. The aim of our research was to analyze the clinical and hormonal characteristics of NFPAs using Knosp and revised Knosp classifications. Furthermore, we aimed to assess the possibility of predicting surgical remission after surgery.

This systematic review evaluates the long-term effectiveness of scleral lenses in improving visual outcomes, patient satisfaction, and safety in patients with keratoconus. A systematic search of six databases (PubMed, Embase, Web of Science, Scopus, Cochrane Library, and MEDLINE) was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria included studies with more than or equal to three months of follow-up, included a minimum of 20 keratoconus patients, published after year 2020 and outcomes reporting visual acuity, comfort or quality of life.
