Before CXL, cones of pediatric keratoconic corneas were located more centrally than in the two older age groups. After CXL, pediatric corneas showed more corneal flattening and more corrected distance visual acuity improvement. Pediatric CXL was equally safe compared to adolescent and adult CXL.

ABSTRACT.The aim of this study was to review the literature on predictive factors for postoperative visual acuity (VA) in surgery for idiopathic epiretinal membrane (ERM). A systematic review of the literature in the databases of PubMed and Embase was performed. The risk of bias was assessed based on predefined criteria and the results were summarized. In total, 1927 studies were retrieved of which 35 were potentially eligible. Nineteen studies were of adequate quality in terms of bias. Preoperative VA, central foveal thickness (CFT) and inner segment/outer segment (IS/OS) integrity on optical coherence tomography (OCT) were most extensively studied. Other preoperative factors studied were severity of metamorphopsia, several OCT parameters, fundus autofluorescence and multifocal electroretinogram. In the current literature, preoperative VA is the only variable consistently associated with postoperative VA. IS/OS integrity on OCT is probably associated, and the severity of metamorphopsia, cone outer segment tips integrity and fundus autofluorescence are possibly associated with postoperative VA. CFT is not associated with postoperative VA. Further studies with adequate methodological quality are needed to confirm these findings. Therefore, an overall prediction model, including different parameters, is still awaited.

This meta-analysis suggests that scleral buckling for macular detachment must preferably be performed within 3 days to optimize visual outcome.

Stabilization after CXL was achieved in mild to moderate cases and advanced cases of progressive keratoconus. The amount of failure was comparable in the 2 subgroups. The CXL-induced flattening was more pronounced in the advanced subgroup.

Background To compare the tolerability of commonly prescribed topical glaucoma medications by determining frequency and bother of side effects, patient satisfaction with their medication, and the chance of discontinuation of eye drops. Methods The tolerability of topical glaucoma medication was studied in glaucoma patients from nine hospitals. The frequency and severity of side effects was investigated together with patient satisfaction with the medication and the probability to change medication due to reported side effects. To register side effects of topical glaucoma medication, patients were requested to fill in a questionnaire based on "the Comparison of Ophthalmic Medications for Tolerability" (COMTOL) questionnaire supplemented with items based on the most frequently observed and severe side effects.Results The number of patients responding was 3,333 (87%). Most patients (79%) were satisfied with their eye medication. The median score for ocular side effects was 58 on a scale ranging from 0 to 320. The probability that medication would be changed by the ophthalmologist at the next visit due to reported side effects occurring since the patients' last or last but one visit to the ophthalmologist was 9%. The most frequently prescribed drugs were timolol, latanoprost, and the fixed combinations of dorzolamide/ timolol (Cosopt®) and latanoprost/timolol (Xalcom®). Only small differences in tolerability were found between these drugs. Conclusions The tolerability of timolol, latanoprost, and the fixed combinations of latanoprost/timolol (Xalcom®) and dorzolamide/timolol (Cosopt®) seem to be comparable. Patients are satisfied with their glaucoma medication and have a low chance of discontinuation of eye drops due to side effects.
