ABSTRACT

BACKGROUND: Glaucoma is a progressive optic neuropathy, remaining asymptomatic for a long time, which makes its early diagnosis difficult. Visual field testing is still the gold standard but is less than ideal. The goal of this study is to assess a pupillometric test, administered passively to the subject for one minute, to measure its sensitivity and specificity in the classification of healthy eyes and glaucomatous eyes, and to evaluate its tolerability compared to visual field testing. METHODS: Forty-five participants were included in this single-center, interventional, prospective study. They underwent 3 monocular pupillometric tests with light stimulation: 6 pupillary responses were recorded during full-field multifocal stimulation (performed twice) and pupillary hippus cycle study. RESULTS: Analysis of spectral power and pupillary measurements with full-field multifocal stimulation provides a 0.94 sensitivity and a 0.88 specificity, a virtually perfect discrimination for early stages of glaucoma. Analysis of pupil cycle time provides a 0.92 sensitivity and a 0.88 specificity for early stages. Acceptability of this test by patients is superior to visual field testing. CONCLUSION: These results show that data from our pupillometric recordings provide a good classification of healthy and glaucomatous eyes and must be confirmed on a larger population.

ABSTRACT

PURPOSE: To evaluate the predisposing factors, management and visual prognosis of intraocular Lens (IOL) dislocation into the posterior segment. METHODS: The cases of posterior IOL dislocation from January 2012 to May 2017 at 2 centers were reviewed. Only eyes with dislocations requiring IOL explantation or repositioning were included. Predisposing factors, interval between cataract surgery and IOL dislocation, circumstances of onset, management, and postoperative complications are reported. RESULTS: 72 eyes of 72 patients were included. The mean age was 67.6 years. 47 patients (68%) were men. The mean time interval from cataract surgery to IOL dislocation was significantly shorter in the out-of-the bag group than the in-the-bag IOL dislocation group (3.8 months vs 132 months, P=0.002). Predisposing factors for out-of-the-bag IOL dislocation were mainly capsular rupture and/or zonular dehiscence (83%) after complicated cataract surgery. The predisposing factors for in-the-bag IOL dislocation were high myopia (40%), pseudoexfoliation syndrome (40%), previous vitrectomy (38%), or Marfan syndrome (3%) with uneventful cataract surgery. The type of luxated implant was mainly a 3-piece foldable IOL (50%), followed by foldable one-piece IOL (28%) and a rigid one-piece IOL (17%). Most cases of posterior chamber IOL dislocation occurred spontaneously (80%) without a trigger event. Management consisted of a posterior approach in 24 cases (33%) or an anterior approach in 48 cases (67%), associated with IOL repositioning in 20 eyes (28%), and IOL replacement in 34 eyes (47%). Finally, 18 eyes (25%) were left aphakic. Postoperative complications occurred in 7 cases (9.7%). CONCLUSIONS: Predisposing factors and time from cataract surgery to IOL dislocation were different for out-of-the bag versus in-the-bag IOL dislocation. Management of IOL dislocation varied considerably, depending on surgeon preference and experience. Surgery for IOL dislocation significantly improved best corrected visual acuity and was associated with a low complication rate.

ABSTRACT

This exploratory clinical trial aims to assess the effect on visual acuity and central corneal thickness of an unpreserved hypertonic ophthalmic solution containing sodium chloride (5%) and sodium hyaluronate, in patients with chronic corneal edema caused by endothelial disease reducing their visual acuity. Twenty patients were enrolled and treated with the hypertonic solution (1 to 2 drops per eye, 4 times a day over 28 days). Progression of visual acuity (ETDRS score) and corneal thickness (ultrasonic pachymetry) was measured from baseline (without treatment) through the treatment period (Day 7 and Day 28). The analyses were performed on 18 patients (Full Analysis Set [FAS] population). The causes of corneal edema were Fuchs endothelial dystrophy in 10 cases and post-cataract surgery endothelial decompensation in 8 patients. The mean visual acuity values for the FAS population compared between baseline (Day-7) and one week of treatment (Day+7) show a significant 5-point VA improvement (P<0.001 paired Wilcoxon test). For corneal thickness, there was also a significant decrease (P=0.033 paired Wilcoxon test). Functional improvement was observed at 28 days of instillation. No adverse events were recorded during the clinical study. In conclusion, the unpreserved hyperosmolar solution containing sodium chloride and sodium hyaluronate significantly improved ETDRS visual acuity after one week of use. In this clinical trial, the solution also showed excellent tolerability results.

ABSTRACT

Several clinical and experimental studies have demonstrated that ocular surface disease is common in glaucoma patients receiving chronic glaucoma drops, and that the preservatives in these drops play a major role in the occurrence of ocular surface disease. These ocular surface changes may induce both symptoms reported by the patients and anterior segment clinical signs, and should be systematically assessed by history and exam in all glaucoma patients. In these patients with ocular surface disease, reducing the amount of preservatives administered to the eye should be strived for, rather than adding additional eye drops to alleviate or mask the side effects of the glaucoma drops.

ABSTRACT

In patients with visual hallucinations, diagnostic strategy is unclearly codified. In patients known to have giant cell arteritis, the main diagnostic assumption is disease relapse. Indeed, this should lead to rapid corticosteroid therapy. However, the Charles Bonnet syndrome, that is a poorly known etiology of visual hallucinations usually observed in elderly people, should be part of the differential diagnosis. We report a 87-year-old woman, with a 2-year history of giant cell arteritis who was admitted with an acute onset of visual hallucinations and who met all the criteria for Charles Bonnet syndrome.
