Normal‑tension glaucoma (NTG) is a multifactorial optic neuropathy which, similar to open‑angle glaucomas, is characterized by progressive retinal ganglion cell death and glaucomatous visual field loss. The major distinction of NTG from open‑angle glaucomas is that the intraocular pressure (IOP) does not exceed the normal range. Missing the major risk factor and target of therapy, the elevated IOP, NTG poses a clinical challenge. Several insightful reviews have been published on the pathophysiology of NTG describing the possible underlying mechanisms. The current literature available also suggests that a significant percentage of patients with NTG (as high as 21%) have a family history of glaucoma, indicating a genetic predisposition to the disease. These facts strengthen the indication that NTG remains an enigmatic process. The aim of this review was to summarize the vascular, mechanical and genetic components considered to be responsible for NTG development and to discuss the mechanisms through which they are involved in the pathogenesis of NTG.

Glaucoma is a group of progressive optic neuropathies that have in common characteristic optic nerve head changes, loss of retinal ganglion cells and visual field defects. Among the large family of glaucomas, primary open‑angle glaucoma (POAG) is the most common type, a complex and heterogeneous disorder with environmental and genetic factors contributing to its pathogenesis. Approximately 5% of POAG is currently attributed to single‑gene or Mendelian forms of glaucoma. Genetic linkage analysis and genome‑wide association studies have identified various genomic loci, paving the path to understanding the pathogenesis of this enigmatic, blinding disease. In this review we summarize the most common variants reported thus far and their possible clinical correlations.

Introduction: We aimed to describe and review the epidemiological aspect of the disease pattern of a series of perimenopausal and postmenopausal women with a histology confirmation of endometriosis. Material and Methods: We retrospectively examined the clinical records of 184 perimenopausal and 46 postmenopausal women with endometriosis. Data were collected and analyzed from 1100 patients’ charts with confirmed endometriosis and involved cases from two different geographical areas, New Haven (US) and Greece. The statistical methods included ײ and the Mann-Whitney U test. In the perimenopausal group (age 45–54 years), there were 184 patients (16.7%) and the postmenopausal group (55–80 years) had 46 (4.2%). The average age of diagnosis was (49 ± 2.3) and (61.2 ± 5.1), respectively (p < 0.01). Results: Advanced endometriosis was more aggressive in the perimenopausal group (p < 0.05); in the same group, we observed a higher left-sided predisposition of endometriosis in comparison with the right side (p < 0.01). Endometrioma was the most common gynecological condition among patients with perimenopausal endometriosis in relation to the postmenopausal group (p < 0.001). Additionally, we found uterine leiomyomata more prominent in the perimenopausal group (p < 0.05). In contrast, adenomyosis was found higher in postmenopausal patients (p < 0.05); further, 24 cases with dry eye we observed. Conclusions: Postmenopausal endometriosis is an important underestimated condition. Although the reported situation is not common, various clinicopathological characteristics were observed in both groups. Clinicians should be aware that there is a correlation between endometriosis and endometriosis-associated ovarian cancer in perimenopausal and postmenopausal age.

To evaluate the efficacy and safety of the low-power, high-frequency electrical current treatment administered by the Rexon-Eye device, in a cohort of patients affected by mixed-type dry eye disease (DED) of medium to severe level. In this prospective, non-randomized, interventional clinical study, eighteen mixed type DED patients were treated. Treatment was a specific type of electrotherapy, Quantum Molecular Resonance (QMR®), administered by means of the Rexon-Eye® device (Resono Ophthalmic, Sandrigo, Italy) with a protocol of one 20-min session per week, for 4 weeks. Patients were examined at baseline and one month after the last treatment, utilizing the Ocular Surface Disease Index (OSDI) questionnaire and clinical signs: non-invasive tear break-up time (NIBUT), Oxford staining, meibum quality, meibography, meibomian gland expressibility, tear meniscus height (TMH), Schirmer's test, ocular inflammation expressed by MMP-9 concentration. Subjective benefit in OSDI was reported (p = 0.013). Improvement was also observed in NIBUT (p < 0.001), Oxford staining (p = 0.002), expressible meibomian glands number (p = 0.001) and meibum quality (p < 0.001). A remarkable benefit was present in inflammation, as evidenced by the reduction of MMP-9 (p = 0.003). Changes, although not statistically significant, were also present in TMH (p = 0.076) and Schirmer's test (p = 0.675), whereas no change was observed in meibography score. No adverse event was reported. In this mixed-type DED patients’ cohort, Rexon-Eye proved to be effective and safe in improving subjective and objective ocular parameters, as well as capable to normalize inflammatory markers.

The purpose of our study is to present a quick surgical procedure for the treatment of Conjunctivochalasis (CCH) and to evaluate its effectiveness. Thirty consecutive patients, in whom CCH was diagnosed on clinical examination, were investigated for the presence of symptoms of dry eye. The 60 eyes were evaluated according to their symptomatology and the 40 symptomatic eyes were grouped in two stages using the LIPCOF (stage 1, one small fold; stage 2, more than two folds but not higher than the tear meniscus) classification and included in the study. After a subconjunctival injection of lidocaine 20 mg/mL, a medium frequency alternating current (RF) was used, adjusted in low power. With a wide tip, redundant conjunctiva was ablated leaving space between the ablations. Postoperative treatment included eye oint.gentamicin 0.3% with dexamethasone 0.03% three times a day for 5 days. At postoperative day 10, conjunctival edema had subsided and conjunctival epithelium was intact after fluorescein staining. Symptoms had improved in all patients. During follow-up, no complication was detected. Mild conjunctival hyperemia was present in all cases but resolved with standard postoperative medications. To conclude, CCh treatment with RF appears to be a safe, quick, and effective surgical technique. Operation time is less than 10 min and can be performed in an outpatient clinic.

Background: We aimed to investigate the clinical importance of conjunctivochalasis (CCH) and, further, to implement a new CCH classification system. Methods: 60 eyes of patients with whom, upon clinical examination, CCH was diagnosed were investigated for the presence of symptoms and signs characteristic of dry eye. The eyes were grouped based on two stages of severity, Stage 1 (minimal/mild) and Stage 2 (medium/severe), for each nasal, middle, and temporal position, and on the extent of CCH folds in each site. Results: In 40 (66.6%) out of 60 eyes, symptoms and signs of CCH were manifest: pain in 25 (41.6%), epiphora in 25 (41.6%), and lacrimal punctum obstruction from conjunctival folds in 22 (36.6%) eyes. Depending on the position of CCH, a greater percentage of symptoms appeared in Stage 2 in the nasal position (78.9%), followed by middle (68.7%) and temporal positions (60%). When TBUT values were compared, statistically significant differences were found proportional to grading (p < 0.001) and position (nasal more severe than temporal, p < 0.001), and such differences were also found when TBUT values of all eyes were compared with those of symptomatic eyes (p = 0.01) and with those of symptom-free eyes (p = 0.002). Conclusions: CCH is a rather frequent and commonly unrecognized condition that should always be considered in differential diagnoses of dry eye.
