ABSTRACT

Central serous chorioretinopathy (CSC) is a disease of unknown etiology, but half-dose photodynamic therapy (hPDT) is well known to be effective for CSC. Infrared reflectance (IR) has been shown to be effective for detecting retinal pigmented epithelial and choroidal lesions, but no reports have focused on chorioretinal changes using IR images after as compared to before hPDT. This study aimed to clarify the features of IR images as well as retinal and choroidal morphological changes before and after treatment with verteporfin hPDT for CSC. We also examined prognostic factors associated with CSC treatment. This was a retrospective study that included 140 eyes of 140 patients (male/female ratio 122:18, mean age 53.4 ± 10.8 years) diagnosed with CSC who underwent hPDT in our hospital during the period from April 2015 to December 2018. We determined changes in visual acuity, therapeutic efficacy, central retinal thickness (CRT), central choroidal thickness (CCT), and IR images at one and three months after hPDT as compared to before treatment. Dry macula was defined as a complete resolution of serous retinal detachment after hPDT. History of smoking, disease duration, presence of drusen, presence of retinal pigment epithelium abnormalities, type of fluorescein angiographic leakage, and presence of choroidal vascular hyperpermeability were investigated as prognostic factors associated with treatment efficacy. CRT and CCT were measured using optical coherence tomography (Spectralis HRA-2; Heidelberg Engineering), and IR images after versus before treatment were compared using ImageJ software (version 1.52) to calculate the mean luminance for a 3 × 3 mm area in the macula. Compared with the values before treatment, CCT, CRT, and visual acuity showed significant improvements at one and three months after treatment, and the mean luminance of IR images was also significantly increased. Furthermore, the luminance on IR images tended to rise, though the values at one month and three months after treatment did not differ significantly. Disease duration was significantly associated with dry macula one month after treatment, and visual acuity and CRT before hPDT were both significantly related to dry macula three months after treatment. IR images tended to improve over time, from before treatment through one and three months after hPDT.

ABSTRACT

A patient with acquired optic disc pit (ODP) maculopathy underwent vitrectomy with anterior capsule transplantation to the ODP and gas tamponade. Structural changes were evaluated by enhanced depth imaging optical coherence (OCT) tomography. During vitrectomy, the eye was confirmed to have preexisting posterior vitreous detachment. Postoperative OCT showed complete closure of the optic pit resulting in rapid absorption of subretinal fluid. The authors' observations suggest that the anterior capsule is a useful material for achieving optic pit closure. To the authors' knowledge, this is the first report describing application of the anterior capsule to the treatment of ODP maculopathy. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:649-652.].

ABSTRACT

BACKGROUND: To evaluate the efficacy of epiretinal membrane removal in patients with good best-corrected visual acuity (BCVA) for improving visual function and quality of life (QOL). METHODS: This prospective case study compared 37 subjects with preoperative BCVA ≦ 0.046 logMAR (Good group) to 35 patients with 0.10-0.52 logMAR (Moderate group) at 3 and 6 months. Linear mixed-effect models were used for statistical analysis. The primary outcome was the horizontal metamorphopsia score (MH) at 6 months postoperatively (post-6 M), while secondary outcomes were postoperative BCVA, vertical metamorphopsia score (MV), aniseikonia, stereopsis and central foveal thickness. In the Good group, QOL was assessed using the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) at 6 and 12 months. RESULTS: MH was significantly improved at post-3 M and post-6 M in the both groups but there were no significant differences between the two groups. MV showed no improvement at the final observation in either group. LogMAR BCVA was significantly improved at post-6 M in the Good group, which had significantly better vision than the Moderate group. Preoperative vertical and horizontal aniseikonia scores remained unchanged in the Good group at post-6 M but worsened in the Moderate group. The NEI VFQ-25 score improved in the Good group, reflecting improved general health, general vision, and mental health. CONCLUSIONS: Early epiretinal surgery for patients with BCVA ≦ 0.046 logMAR was effective for improvement of HM, BCVA, and QOL and prevented worsening of aniseikonia.

ABSTRACT

PURPOSE: The aim of this study was to clarify the 1-year outcomes of pro re nata (PRN) and bimonthly intravitreal injections of aflibercept (IVA) for typical neovascular age-related macular degeneration (tAMD) after the initial 3 monthly IVA. METHODS: We conducted a prospective, interventional study. Fifty-eight treatment-naïve patients with tAMD were randomly assigned to the PRN (30 patients) or the bimonthly (28 patients) treatment group. Both groups initially received 3 monthly IVA. Visual acuity, central macular retinal thickness (CRT), and central choroidal thickness (CCT) were evaluated at 12 months. Subanalysis was performed to identify factors associated with the best-corrected visual acuity (BCVA). RESULTS: BCVA was significantly improved only in the bimonthly group at 12 months. CRT and CCT were significantly decreased in both groups. Subanalysis showed that the only factor associated with BCVA improvement at 12 months was the existence of pigment epithelial detachment at baseline. CONCLUSIONS: BCVA showed significant improvement only in the bimonthly group but not in the PRN group at 12 months.
