PurposeTo report the effect of intravitreal ranibizumab therapy for serous and vascular pigment epithelial detachments (PED) associated with choroidal neovascularisation (CNV) secondary to age-related macular degeneration (AMD).MethodsIn a prospective study, best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) data were collected for 62 eyes of 62 patients, with serous or vascular PED associated with CNV secondary to AMD. Intravitreal ranibizumab 0.5 mg was administered with a loading phase of three consecutive monthly injections, followed by monthly review with further treatment, as indicated according to the retreatment criteria of the PrONTO study. The change in visual acuity and PED height from baseline to month 12 after the first injection was determined.ResultsSixty-one eyes of 61 patients (one of the patients developed retinal pigment epithelial tear and was excluded from the study) were assessed at the 12-month follow-up examination. There were two types of PED, including vascular PED in 32 patients (Group A) and serous PED (Group B) in 29 patients. The mean improvement of mean BCVA from baseline to 12 months was 0.09 logMAR (Logarithm of the Minimum Angle of Resolution) in Group A and 0.13 logMAR in Group B. Both groups showed significant improvement of the mean BCVA 12 months after the first injection compared with the baseline value (P < 0.05). In relation to the PED height, the mean decrease of mean PED height from baseline to 12 months was 135 μm in Group A and 180 μm in Group B. Both groups showed significant reduction of the PED height during the follow-up period (P < 0.01). The PED anatomical response to ranibizumab was not correlated with the BCVA improvement in any of the groups. Apart from one patient who developed pigment epithelial tear no other complications were documented.ConclusionRanibizumab is an effective and safe treatment for improving vision in patients with serous and vascular PED, although the anatomical response of the PED to ranibizumab may not correlate directly with the visual outcome.

Although decompression retinopathy has previously been described after penetrating glaucoma surgery, the condition can also occur after uncomplicated deep sclerectomy. Despite the dramatic presentation, the prognosis remains favorable.

Purpose Contemporary monovision techniques use premium intraocular lenses (IOLs), either in both eyes or at least in the non-dominant one. Primary objective of this study was to compare the efficacy of premium monovision (implantation of the trifocal diffractive Panoptix IOL in the non-dominant eye and the bifocal hybrid refractive-diffractive Restor IOL in the dominant eye), against bilateral myopic monovision (implantation of the monofocal SN60WF IOL targeting −0.50 D in the dominant eye and −1.25 D myopia in the non-dominant one), hybrid monovision (implantation of Panoptix in the non-dominant eye and SN60WF in the dominant eye) and bilateral trifocal implantation (with bilateral Panoptix implantation). Methods This is a prospective, comparative, clinic-based trial. Cataract patients populated four study groups: Monovision Group (MoG), Multifocal Lens Group (MfG), Hybrid Monovision Group (HmG) and Premium Monovision Group (PmG). Binocular Uncorrected Distance Visual Acuity (UDVA), Uncorrected Reading Acuity and Critical Print Size at 60cm (UIRA, UICPS) and at 40cm (UNRA, UNCPS), contrast sensitivity, vision-related functional impairment, dysphotopsia symptoms and spectacle dependence were evaluated 6 months following the operation of the second eye. A mathematical model was constructed, which calculated the relative efficacy of each surgical intervention. Results A total of 120 participants were recruited and populated equally the study groups. Significant improvement of preoperative UDVA was observed in all study groups. No significant differences could be detected in postoperative UDVA and UIRA (p = 0.24) among study groups, while significant differences were noticed in UICPS (p = 0.04), UNRA (p = 0.02) and UNCPS (p = 0.01). Dysphotopic phenomena (glare and shadows) were significantly more in the MfG arm followed by the PmG group (p = 0.04 and p = 0.02, respectively), while perceived difficulty and spectacle independence rates were significantly better in PmG group. PmG presented the best overall relative efficacy. Conclusion All surgical techniques present satisfactory outcomes. Premium monovision seems to demonstrate the best outcomes.

Purpose Primary objective of this study was to identify potential difficulties and/or discomfort when using a facemask. Moreover, to explore the impact of spectacles, contact lenses and visual acuity on the compliance to the facemask directive. Methods This is a prospective study that was conducted at the Department of Ophthalmology, University Hospital of Alexandroupolis, Greece between June 2020 and August 2020. Greek speaking citizens with permanent residency in Greece above 18 years old were included. A custom questionnaire (DeMask-20) was constructed and validated, which pertained to the perceived difficulty and discomfort when using a facemask. It contained 20 items grouped in 8 subscales (driving, near vision, distance vision, ocular discomfort, role limitation, collaboration, dependency on others, emotional stress). Perceived difficulty and discomfort when using a facemask, compliance and correlations of compliance with DeMask-20 scores, demographics, spectacle and/or contact lens use, and visual acuity were evaluated. Results The number of factors was determined through factor analysis. Cronbach’s alpha ranged from 0.716 for the “Role limitation” subscale to 0.938 for “Ocular discomfort” subscale. 1,214 participants (402 men, 812 women, mean age 36.79±12.50 years) completed the DeMask-20 instrument. Mean DeMask-20 score of all study participants was 3.79±0.71. Significant differences in DeMask-20 score were detected in gender (p = 0.009), spectacle use (p = 0.034), contact lens use (p = 0.049), and binocular distance visual acuity (bDVA) (p = 0.001). Mean compliance of all participants was 4.05±0.96. Men, people <50 years and spectacle wearers showed significantly worse compliance (p<0.05). Moreover, professional workers and professional drivers demonstrated significantly better compliance (p = 0.008 and p = 0.047). Significant correlation was detected between compliance and DeMask-20 score (p<0.001, R2 = 0.471). Significant correlations were detected with driving, near vision, distance vision, collaboration, role limitation, emotional stress (p<0.05, R2: 0.386–0.493). Conclusions Factor analysis suggested that the DeMask-20 instrument demonstrates adequate validity, while Cronbach’s alpha indicated sufficient internal consistency of all subscales. This study provided the necessary methods that could evaluate compliance trends and the efficacy of healthcare interventions against COVID-19. Our outcomes suggest that young males who use spectacles should be targeted by Greek Healthcare authorities in order to improve compliance rates.
