Fundus autofluorescence findings in central serous chorioretinopathy using two different confocal scanning laser ophthalmoscopes: correlation with functional and structural status.

PURPOSE: To compare autofluorescence (AF) findings using wide-field (Optomap) and conventional (HRA-AF) confocal scanning laser ophthalmoscopy (cSLO) systems in patients with central serous chorioretinopathy (CSC), and to investigate the correlations between AF findings and functional and anatomical status. METHODS: Optical coherence tomography (OCT) and AF images were compared in 73 eyes with serous retinal detachment (SRD) (group A) and 30 eyes without SRD (group B). We evaluated AF findings from the SRD region, atrophic area, and foveola. Correlations between AF findings and outer retinal abnormalities in OCT and visual acuity (VA) were analyzed. RESULTS: Optomap-AF was more effective than HRA-AF in identifying the margins of a detached area (P = 0.001) in group A, and for monitoring mild outer retinal damage (P = 0.041) in group B. The foveolar AF grades in both instruments were significantly correlated with VA and central foveal thickness (CFT) in both group A (Optomap, VA r s = 0.33, P = 0.012; CFT r s = -0.38, P = 0.002; HRA, VA r s = 0.62, P < 0.001; CFT r s = -0.70, P < 0.001) and group B (Optomap, VA r s = 0.71, P < 0.001, CFT r s = -0.78, P < 0.001; HRA, VA r s = 0.40, P = 0.026, CFT r s = -0.40, P = 0.030). CONCLUSIONS: Optomap-AF was found to be advantageous for monitoring subretinal status in eyes with SRD, and more accurately reflected mild outer retinal changes in eyes without SRD. Foveolar AF grades of both imaging modalities were significantly correlated with functional and anatomical status.

Anti-Vascular Endothelial Growth Factor with Gas for Submacular Hemorrhage.

PURPOSE: To investigate the treatment outcome of pneumatic displacement and intravitreal anti-vascular endothelial growth factor (VEGF) for submacular hemorrhage (SMH) from exudative age-related macular degeneration (AMD). METHODS: Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were measured at baseline and at 1, 3, and 6 months after initial treatment in 72 eyes of 72 patients treated with a combination of pneumatic displacement and anti-VEGF injection for SMH from exudative AMD. RESULTS: Best-corrected visual acuity and CFT showed significant improvement from baseline during the 6-month follow-up period (logarithm of the minimum angle of resolution BCVA from 1.80 to 1.00, CFT from 886 to 383 µm, p < 0.001, respectively). The decrease in subretinal hemorrhage was greater than that in subretinal pigment epithelial hemorrhage at 1 month after initial treatment (p < 0.001). In eyes with symptoms for less than 30 days, higher reflectivity of hemorrhage on optical coherence tomography and higher CFT were associated with lower BCVA after 6 months of treatment (reflectivity B = 0.335, p = 0.007; CFT B = 0.001, p = 0.003). CONCLUSIONS: The combination of pneumatic displacement and intravitreal anti-VEGF is a useful treatment option for SMH secondary to AMD. Higher baseline CFT and higher reflectivity of hemorrhage were associated with lower BCVA 6 months after initial treatment.

Primary and additional treatment preference in aggressive retinopathy of prematurity and type 1 retinopathy of prematurity.

OBJECTIVE: This study aimed to evaluate the preference for antivascular endothelial growth factor (anti-VEGF) versus laser ablation therapy as primary and additional treatment in aggressive retinopathy of prematurity (ROP) and type 1 ROP. METHODS: This multicentre retrospective study was conducted at nine medical centres across South Korea. A total of 94 preterm infants with ROP who underwent primary treatment between January 2020 and December 2021 were enrolled. All eyes were classified as having type 1 ROP or aggressive ROP. Data on the zone, primary treatment chosen, injection dose, presence of reactivation and additional treatment were collected and analysed. RESULTS: Seventy infants (131 eyes) with type 1 ROP and 24 infants (45 eyes) with aggressive ROP were included. Anti-VEGF injection was selected as the primary treatment in 74.05% of the infants with type 1 ROP and 88.89% with aggressive ROP. Anti-VEGF injection was selected as the ROP was located in zone I or posterior zone II, and laser ablation was selected when it was located in zone II. The anti-VEGF injection doses varied and tended to be higher in the aggressive ROP group. Infants with aggressive ROP were 2.08 times more likely to require additional treatment than those with type 1 ROP. When ROP reactivation occurred, laser therapy was preferred as an additional treatment. CONCLUSION: In Korea, the preference for anti-VEGF therapy or laser therapy differed according to ROP subtype, zone and primary or secondary treatment. These findings suggest that ROP treatment are considered according to ROP subtype, location and reactivation.

Clinical outcomes of combined pars plana vitrectomy and scleral fixation of the intraocular lens with a suspension bridge method in eyes with aphakia or insufficient capsular support.

PURPOSE: To describe a modified technique of scleral fixation for intraocular lens (IOL) implantation and report the clinical outcomes of combined pars plana vitrectomy and scleral IOL fixation using the suspension bridge method. METHODS: This retrospective case series included 57 eyes (56 patients) of aphakia or phakic and pseudophakic eyes with insufficient capsular support that underwent IOL implantation or dislocated IOL repositioning with scleral fixation using the 'suspension bridge' method by a single surgeon between 1 July 2010 and 1 March 2019. Preoperative status, changes in visual acuity, refractive outcomes as spherical equivalent and related complications were assessed with a minimum follow-up of 3 months. RESULTS: The mean follow-up period was 25.5 ± 25.4 months. Preoperative visual acuity (logarithm of the minimum angle of resolution) was 1.32 ± 0.68 (20/400 Snellen), and it significantly improved to 0.80 ± 0.53 (20/125), 0.59 ± 0.56 (20/80) and 0.24 ± 0.37 (20/35) at 1 week, 1 month and 3 months, respectively (p < 0.001). Postoperative complications included corneal wound dehiscence (n = 1), vitreous incarceration (n = 1), optic-iris capture (n = 6) and cystoid macular oedema (n = 1). The above-mentioned complications were successfully corrected with simple procedures. However, one case of IOL dislocation required reoperation. CONCLUSION: The modified technique of the suspension bridge method precludes the need for a scleral flap, with the advantage of easy adjustment of the IOL position. It is a simple and feasible technique with good surgical results and low complication rates.
