ABSTRACT
Background: Preeclampsia is one of the hypertensive disorders in pregnancy that contributes significantly to maternal and fetal morbidity and mortality, with the impact felt more in developing countries. It is characterized by endothelial dysfunction and vasospasm of vessels which can be observed by an ocular fundal examination. The aim of this study was to determine the ocular fundus findings of women with preeclampsia. Methods: This was a cross-sectional study, carried out at the University of Benin Teaching Hospital involving a total of 220 pregnant women. The women were divided into two groups of 110 pregnant women (A&B).Their Age and Gestational age was cross-matched and retinopathy graded according to Keith and Wagner classification. Group A was made up of Preeclamptic women and Group B was made up of healthy pregnant women. Visual acuity was measured using Snellens' chart, and the fundus was examined with direct ophthalmoscope. Results: This showed that the retinal changes observed in the preeclamptic women were associated with their age (P = 0.009), gestational age (P = 0.044), blood pressure (P = 0.001), Proteinuria (P = 0.001), Severity of the disease (P = 0.001), visual acuity (P = 0.035) as well as with the visual symptoms (P = 0.001) but not statistically significant with the gravida (P = 0.799). Conclusion: Our study highlights the importance of timely ophthalmoscopy which helps to assess severity of disease (pre-eclampsia) which affects the decision of induction of delivery to predict and prevent possible complications which in turn immensely helps in judicious management of disease. Also, the study revealed that preeclamptic women who are multigravida are more likely to have retinopathy than primigravid

0.05). Similarly, no significant difference was detected in retinal arteriolar tortuosity (Z=0.91) and venular tortuosity (Z=1.31) (both p>0.05). However, the retinal arteriolar FD (mean difference: −0.03, 95% CI: −0.05, −0.01) and venular FD (mean difference: −0.03, 95% CI: −0.05, −0.02) were associated with cognitive impairment.CONCLUSIONS: A smaller retinal microvascular FD might be associated with cognitive impairment. Further large-sample and well-controlled original studies are required to confirm the present findings.

PURPOSE: To compare the intraocular pressure (IOP) in diabetic macular edema (DME) patients and macular edema associated with branch retinal vein occlusion (BRVO) patients after intravitreal preservative-free Triamcinolone injection.METHODS: This study included 36 patients diagnosed with DME and 44 patients diagnosed with BRVO with macular edema. Both groups were treated with intravitreal preservative-free Triamcinolone (Maqaid®, Wakamoto Pharmaceutical Co., Ltd., Tokyo, Japan) injection, and we compared the IOPs of the two groups determined before injection and at 1, 2, 3, and 6 months after injection. We also compared the IOP elevation ratios and durations, and central foveal thickness (CFT) changes using optical coherence tomography.RESULTS: In both groups, there was no statistical significance in the IOP before injection and at 1, 2, 3, and 6 months after injection. However, the IOP elevation ratio in the DME patients (38.9%) was significantly higher than that in the BRVO patients (15.9%) (p = 0.02). The duration of IOP elevation in the DME patients (1.14 ± 1.85 months) was significantly longer than that in the BRVO patients (0.30 ± 1.20 months) (p = 0.03). When the IOP was not controlled, we used IOP-lowering agents, and two patients in the DME were treated with glaucoma surgery. There was no statistical significance in the CFT before injection and at 1, 2, or 3 months after injection between the two groups (p = 0.72, p = 0.26, p = 0.66, p = 0.34, respectively). However, the CFT after 6 months was 328 ± 103 µm in the DME group and 434 ± 189 µm in the BRVO; this difference was significant (p < 0.01).CONCLUSIONS: Intravitreal injection of preservative-free Triamcinolone was effective in the treatment of both DME patients and macular edema patients associated with BRVO. Furthermore, Triamcinolone was more safely injected in macular edema associated with BRVO patients than in DME patients.

PURPOSE: To evaluate the effectiveness of 0.1% topical bromfenac as an adjunctive treatment with intravitreal bevacizumab (IVB) injection for branch retinal vein occlusion (BRVO) patients.METHODS: We retrospectively evaluated 68 eyes of 68 patients with macular edema (ME) secondary to BRVO who were treated with IVB injection and followed up for at least 12 months. Of the 68 eyes, 38 were treated with IVB combined with 0.1% topical bromfenac and 30 were treated with IVB alone. IVB reinjection was performed in cases of recurrence. The primary outcome measurement was the number of IVB injections. Changes in the best-corrected visual acuity (BCVA) and central foveal thickness (CFT) during the 12-month follow-up were compared.RESULTS: There was no significant difference in the BCVA or CFT between the two groups at the initial and final examinations. However, the number of IVB injections was significantly lower in the 0.1% bromfenac-treated eyes (p < 0.01) than in the control eyes (4.1 ± 0.7 vs. 5.0 ± 0.6 times).CONCLUSIONS: Compared to IVB monotherapy, topical bromfenac as an adjunctive treatment with IVB injection of eyes with ME secondary to BRVO did not affect visual outcomes, but it reduced the number of IVB injections.

PURPOSE: To report a case of non-glaucomatous retinal nerve fiber layer (RNFL) defect associated with paravascular inner retinal defect (PIRD) in a patient with idiopathic epiretinal membrane (ERM).CASE SUMMARY: A 70-year-old male who was diagnosed with ERM in his right eye and pseudoexfoliative glaucoma in his left eye visited our clinic. His intraocular pressure was 14 mmHg in both eyes while using topical hypotensive medications in both eyes. His right eye showed no glaucomatous change of the optic disc head, and also no glaucomatous visual field defect on standard automated perimetry. Red-free fundus photography and swept-source optical coherence tomography showed an ERM and wedge-shaped RNFL defect starting from the PIRD, not the optic disc head. He was diagnosed with non-glaucomatous RNFL defect in the right eye and was told to stop using topical hypotensive medication for the right eye. After 2 years of discontinuing the medication, the IOP was within the normal range, the RNFL defect showed no progression, and the visual field remained stationary.CONCLUSIONS: A non-glaucomatous RNFL defect can develop in association with PIRD in patients with idiopathic ERM. Examinations for PIRD as well as evaluation of the optic disc head are therefore necessary in patients with ERM and RNFL defect.

PURPOSE: To compare the visual acuity and retinal thickness in patients with an idiopathic epiretinal membrane (ERM) after vitrectomy and membranectomy using two different methods.METHODS: This retrospective observational study included 77 eyes (32 eyes in the diamond-dusted membrane scraper [DDMS] group, and 45 eyes in the intraocular forceps [IOF] group) of 77 patients with idiopathic ERM who underwent pars plana vitrectomy and membranectomy. The main outcome measures were best-corrected visual acuity (BCVA, logMAR) and mean retinal thickness.RESULTS: In the IOF group, the BCVA at postoperative 1 week was significantly lower than at baseline and had improved at 12 weeks after surgery. In the DDMS group, the BCVA at postoperative 1 week showed no significant difference at baseline and had improved at 4 weeks after surgery. The central macular thickness at postoperative 6 months was significantly lower than at baseline (all, p < 0.001); there was no significant difference between the two groups (p = 0.400). The postoperative macular thickness of the DDMS group was significantly lower than that of the IOF group in the inner inferior and outer inferior areas at postoperative 12 weeks and 4 weeks (p = 0.046 and p = 0.039, respectively). Five eyes of the DDMS group and 15 eyes of the IOF group developed cystoid macular edema, 14 eyes of that improved without treatment.CONCLUSIONS: In patients with ERM, the use of DDMS or IOF for vitrectomy and membranectomy both resulted in improved visual acuity and decreased mean retinal thicknesses.

PURPOSE: To investigate correlations between macular retinal ganglion cell (RGC) layer thickness and best-corrected visual acuity (BCVA) and visual field parameters in patients with bilateral temporal optic atrophy.METHODS: Thirty eyes of 15 patients with bilateral temporal optic atrophy and 30 eyes of 15 normal subjects that were age- and sex-matched were included in the study. We measured the thicknesses of the RGC layers of posterior poles using optical coherence tomography volume scanning. The RGC layer was divided into nine zones based on the Early Treatment of Diabetic Retinopathy Study baseline. Possible correlations of the RGC layer with the BCVA and visual field parameters were determined.RESULTS: The RGC layer thickness was significantly thinner in all patients compared to those in the control group (p = 0.001). The RGC layer thicknesses in the inner superior, inner temporal, inner inferior, and inner nasal areas were significantly correlated with the BCVA (r = −0.650, r = −0.626, r = −0.616, and r = −0.636, respectively; p = 0.000). The RGC layer thicknesses in the outer superior, outer temporal, outer inferior, and outer nasal areas were significantly correlated with the mean deviation of the visual field test (r = 0.470, r = 0.349, r = 0.496, and r = 0.469, respectively; p < 0.05).CONCLUSIONS: In patients with bilateral temporal optic atrophy, the RGC layer thickness in the medial region was correlated with the BCVA, and the RGC layer thickness in the lateral region was correlated with the mean deviation of the visual field test.

PURPOSE: To report a case of retinal toxicity after an intravitreal ganciclovir injection to treat acute retinal necrosis in an eye filled with silicone oil.CASE SUMMARY: A 56-year-old male presented with ocular pain and visual loss in his right eye. His best-corrected visual acuity was 20/25, inflammatory cells in the anterior chamber, multiple retinitis lesions and retinal vessel occlusions in the peripheral retina and vitreous opacity were showed. Acute retinal necrosis was suspected, anterior chamber polymerase chain reaction (PCR) test was done. Aciclovir 2,400 mg/day intravenously and ganciclovir 2.0 mg were administered by intravitreal injection. After 4 days, retinitis was worsened and PCR test was positive for varicella zoster virus. Ganciclovir intravitreal injections were increased twice a week. After 16 days, retinal detachment occurred, so scleral encircling, vitrectomy, laser photocoagulation, and silicone oil tamponade were conducted. Ganciclovir 1.0 mg was injected at the end of surgery. The patient's visual acuity decreased to hand motion, and multiple crystal deposits with multiple retinal hemorrhages were observed in the right eye the next day. Visual acuity did not recover and optical coherent tomography showed that the macula was thinned.CONCLUSIONS: Visual loss seemed to be related with the retinal toxicity of ganciclovir. The increased local concentration due to the silicone oil tamponade is thought to have caused the toxicity.

Herpes simplex virus (HSV) is a common pathogen, that causes a broad spectrum of diseases, ranging from minor skin infections to severe encephalitis and widespread infections. Acute retinal necrosis (ARN), one of the most serious manifestations of HSV infection, is defined as a rapidly progressing necrotizing retinopathy that presents discrete areas of circumferential retinal necrosis, along with signs of uveitis, vitreitis, and retinal vasculitis. We encountered a case of a female infant, born at 33 weeks of gestation with a body weight at birth of 2,080 g, who had ARN and encephalomalacia due to HSV infection. ARN associated with HSV infection should be suspected when nonspecific retinal exudates are observed in neonates, especially preterm infants.

PURPOSE: To assess the clinical efficacy for early detection of glaucoma using custom-built image software visualizing translucent retinal nerve fiber layer thickness (RNFLT) that is graphed based on a normative database. METHODS: This prospective study was conducted using a normative database constructed with RNFLT data of 151 healthy Korean eyes. The reference lines of the mean, the lower 5%, and the lower 1% limit were visualized as a translucent RNFLT graph produced by our software after inputting each subject's major retinal artery position and overlaying the results onto the RNFLT measurements. Fifty-eight additional healthy control and 79 early-glaucoma eyes were collected for the validation group. If a subject's RNFLT graph was outside the reference line of the lower 1% limit, the graph was defined as abnormal. The lower 1% limit, which was generated by three criteria (criterion 1, built-in software; criterion 2, axial-length data; criterion 3, major retinal artery data), was used to address the difference of agreement with a standard answer. RESULTS: For criteria 1, 2, and 3, the accuracy of our custom-built software was significantly higher than that of the manufacturer's database (kappa of 0.475 vs. 0.852 vs. 0.940; sensitivity of 62.0% vs. 91.1% vs. 97.5%, respectively) maintaining high specificity (87.9% vs. 94.8% vs. 96.6%, respectively). CONCLUSIONS: The custom-built imaging software with the constructed RNFLT normative database showed high clinical efficiency for early detection of glaucoma with negligible user-related variability.

PURPOSE: To evaluate the efficacy of switching to aflibercept in diabetic macular edema (DME) with suboptimal response to previous anti-vascular endothelial growth factor (anti-VEGF) injections. METHODS: A prospective interventional case series study recruited patients from a single center diagnosed with DME with suboptimal response to anti-VEGF injections. Three consecutive monthly injections of aflibercept were performed. The primary outcome measure was mean change in visual acuity after switching to aflibercept. RESULTS: Forty-two patients (42 eyes) were included. Baseline logarithm of the minimum angle of resolution (logMAR) visual acuity was 0.87 ± 0.23 and improved significantly to 0.62 ± 0.29, 0.56 ± 0.34, and 0.46 ± 0.35 at 1, 2, and 3 months, respectively, after the first injection. Mean baseline retinal thickness was 451.57 ± 107.09 µm and decreased significantly at 1, 2, and 3 months after switching to aflibercept (346.52 ± 79.03, 328.24 ± 81.98, and 313.71 ± 85.79 µm, respectively). Both visual improvement and mean change in retinal thickness were significant in patients with pre-aflibercept best-corrected visual acuity less than 1.0 logMAR but were not significant in patients with best-corrected visual acuity more than 1.0 logMAR. CONCLUSIONS: Switching to aflibercept in DME patients with an unsatisfactory response to previous anti-VEGF injections provided acceptable short-term visual and retinal architectural improvement.

PURPOSE: We detected retinal nerve fiber layer (RNFL) defects using a confocal scanning laser ophthalmoscopy (CSLO) with both blue and green laser sources and evaluated image quality based on laser wavelength. METHODS: This was a retrospective observational case study. Blue and green CSLO images of 181 eyes with suspected glaucoma were evaluated and compared. Three independent observers identified the presence of RNFL defects and determined which CSLO imaging source provided superior visibility of the defect. After assessing the defect imaging by laser source, demographics and image quality indices of optical coherence tomography between blue better and green better groups were analyzed. RESULTS: Both blue and green CSLO showed high discriminating ability for RNFL defects. The discriminating ability of blue CSLO was significantly greater than that of green CSLO (p = 0.004). Among eyes with a detectable RNFL defect, 61.8% were better visualized with the blue laser compared to the green laser. Compared with the blue better group, the green better group was significantly older (p = 0.009), had a greater proportion of females (p = 0.005), had poorer best-corrected visual acuity (p = 0.001), more severe cataracts (p = 0.001), lower signal strength (p = 0.003), and poor image quality indices (p = 0.001). CONCLUSIONS: Both blue and green CSLO imaging was useful for detecting RNFL defects, but blue CSLO was superior to green CSLO in quality of RNFL defect imaging in most patients with clear media.

PURPOSE: To determine the origin of epiretinal proliferation (EP), a condition that is occasionally observed in lamellar hole and macular hole cases, and EP outcomes after vitrectomy. METHODS: This is a retrospective observational case review of 17 eyes with EP that underwent vitrectomy, EP dissection, and internal limiting membrane peeling between January 2013 and December 2016. Surgical specimens of EP tissue were successfully obtained from 5 cases and they were analyzed after immunohistochemical staining. Postoperative outcomes, including best-corrected visual acuity (BCVA) and macular configuration in spectral domain-optical coherence tomography, were reviewed. RESULTS: Mean BCVA improved from 0.54 ± 0.36 logarithms of the minimum angle of resolution preoperatively to 0.32 ± 0.38 logarithms of the minimum angle of resolution postoperatively (p = 0.002). BCVA improved in 13 eyes and remained unchanged in four eyes. No cases experienced vision decline after surgery. All 17 patients' lamellar hole or macular hole were successfully closed. Despite hole closure, ellipsoid zone defects were not corrected in 11 of the 17 patients. In immunohistochemical analyses, anti-glial fibrillary acidic protein and pan-keratin (AE1/AE3) were positive, but synaptophysin, anti-α-smooth muscle actin, and anti-CD68 were negative. CONCLUSIONS: The epiretinal proliferative membrane seems to originate from Müller cells, not from the vitreous. It is unclear whether retinal pigment epithelia also contribute to EP formation. Gentle handling and preservation of the epiretinal proliferative tissue is crucial for successful surgical outcomes.

PURPOSE: To compare parameters of confocal scanning laser ophthalmoscopy (Heidelberg Retinal Tomograph [HRT] II) in high myopia with age- and sex-matched emmetropes. METHODS: A hospital-based cross-sectional study was conducted among Nepalese subjects aged 18 to 35 years at BP Koirala Lions Centre for Ophthalmic Studies, Institute of Medicine, Maharajgunj, Kathmandu from November 2015 to October 2016. Fifty consecutive subjects with high myopia (spherical equivalent ranging from −6.00 to −12.00 diopters) and age- and sex-matched emmetropic subjects were enrolled for comparison. Correlations between disc area and other HRT parameters, asymmetry between the right and left eyes, and comparisons between male and female subjects in both high myopic and emmetropic groups were evaluated. RESULTS: Disc area was not significantly (p = 0.11) larger in high myopic eyes than in emmetropic eyes. HRT parameters in highly myopic eyes involved smaller cup parameters and greater rim parameters compared with emmetropic eyes. Disc area was found to be significantly positively correlated with inter disc parameters and significantly negatively correlated with rim to disc area ratio in the high myopia group. Disc area and other intra-disc parameters showed significant correlations between right and left eyes in both high myopia and emmetropia, and no significant differences between males and females from a Nepalese population. CONCLUSIONS: Characteristics of HRT parameters in high myopic eyes involved smaller cup parameters and greater rim parameters compared with emmetropic eyes in a Nepalese population. The effect of disc area on HRT parameters differed significantly only in height variation contour by emmetropic eyes.

PURPOSE: To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after resolution of serous retinal detachment. METHODS: A total of 31 patients diagnosed with idiopathic unilateral CSC were included in this study. The changes of AXL according to serous retinal detachment were examined. The keratometric value and AXL were measured using partial coherence interferometry. Serous retinal detachment and central macular thickness (CMT) were measured by spectral domain optical coherence tomography. RESULTS: The mean age of the 31 CSC patients, including 19 males, was 42.7 years. The AXL was significantly increased from 23.41 to 23.58 mm after resolution of serous retinal detachment (p < 0.001). The CMT was significantly decreased from 413.4 to 226.8 µm after resolution of serous retinal detachment (p < 0.001). The differences in AXL correlated with CMT differences and subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively), and the best-corrected visual acuity was significantly different after resolution of serous retinal detachment (p < 0.001). CONCLUSIONS: In unilateral idiopathic CSC with serous retinal detachment, a shortened AXL in the acute phase was restored after resolution of serous retinal detachment.

PURPOSE: To evaluate the effect of epiretinal membrane (ERM) on the outcomes of intravitreal dexamethasone implant (Ozurdex®, Allergan, Irvine, CA, USA) treatment for macular edema (ME) secondary to branch retinal vein occlusion (BRVO). METHODS: Thirty eyes of 30 patients who received Ozurdex treatment for ME secondary to BRVO, and were followed-up for at least 6 months were retrospectively reviewed. Patients were divided into two groups based on the presence (ERM [+] or absence ERM [−]) of ERM at baseline. The best-corrected visual acuity (BCVA), central foveal thickness (CFT), recurrence of ME, and retreatment rate were evaluated at baseline, 1, 3, and 6 months after Ozurdex injection. RESULTS: Ten eyes of 30 eyes (33%) showed ERM at baseline. While the mean CFT was significantly reduced at 1 month after Ozurdex injection, it began to increase gradually thereafter in both groups. The ERM (+) group showed a significantly higher mean CFT than the corresponding values of the ERM (−) group at 1 (p = 0.022) and 6 months (p = 0.001) after Ozurdex injection. However, no significant difference was found in the BCVA between the two groups at every visit. The proportion of eyes with ME was significantly higher in the ERM (+) group (90%) than that in the ERM (−) group (35%) at 6 months after Ozurdex injection (p = 0.009). There were no significant differences between the two groups in the percentage of retreatment, time to retreatment, and type of materials used for retreatment. CONCLUSIONS: In patients with ME secondary to BRVO, the treatment effect of Ozurdex was low and the duration of treatment was short when ERM was concurrently present. However, the presence of ERM did not significantly affect visual outcomes after treatment with Ozurdex.

PURPOSE: To evaluate the efficiency of a surgical method using original breaks to drain subretinal fluid without using retinotomy and perfluorocarbon liquid for patients with rhegmatogenous retinal detachment (RRD). METHODS: A retrospective chart review comparing 41 eyes of 41 patients who received vitrectomy, and used original breaks to drain subretinal fluid without using perfluorocarbon liquid, and 40 eyes of 40 patients who received vitrectomy using perfluorocarbon liquid for simple RRD between February 2014 and December 2017 was conducted. All patients were followed for a minimum of 6 months after surgery. RESULTS: The primary anatomical success percentages were 97.6% and 97.5% for groups that did not and did use perfluorocarbon liquid, respectively. Retinal detachment recurred in one eye from both groups. The final success percentage was 100%. The preoperative mean logMAR best-corrected visual acuity (BCVA) of 0.87 ± 0.80 improved to 0.30 ± 0.30 at postoperative 6 months for the group that did not use perfluorocarbon liquid, while it improved from 0.86 ± 0.71 to 0.42 ± 0.52 for the group that did use perfluorocarbon liquid. Both groups showed significant BCVA improvement (p < 0.01). There was no significant difference in the incidence of complications caused by the use of perfluorocarbon liquid. CONCLUSIONS: Using original breaks to drain subretinal fluid without perfluorocarbon liquid in cases with RRD may be an effective and safe surgical technique for functional and anatomical recovery without serious complications.

PURPOSE: To measure the thicknesses of the circumpapillary retinal nerve fiber layer (RNFL) and macular retinal ganglion cell-inner plexiform layer (GCIPL) by optical coherence tomography (OCT) in healthy Korean children and adolescents. METHODS: Circumpapillary RNFL and macular GCIPL thicknesses were measured by OCT in 352 healthy eyes of 352 children and adolescents (child-adolescent group) aged 5–17 years and in 159 healthy eyes of 159 adults (adult group) aged 18-75 years. The difference in RNFL and GCIPL thicknesses between the groups and the effects of age and refractive errors on the measurements were evaluated. RESULTS: The mean age of the children and adults were 9.7 ± 3.6 and 44.7 ± 15.7 years, respectively. The mean of the average RNFL and GCIPL thicknesses were 103.1 ± 9.2 and 85.7 ± 4.6 µm, respectively, in the children group and 97.8 ± 8.2 and 82.9 ± 4.4 µm, respectively, in the adult group. The child-adolescent group had greater RNFL and GCIPL thicknesses compared to the adult group in all areas (p < 0.05) with the exception of the RNFL thickness in the temporal quadrant (p = 0.555). A thinner RNFL and thinner GCIPL were significantly associated with older age and greater myopia (p < 0.001). CONCLUSIONS: The mean RNFL and GCIPL thicknesses measured by OCT in the healthy eyes of children and adolescents were 103.1 and 85.7 µm, respectively. Children and adolescents had a thicker RNFL and GCIPL compared to adults.

PURPOSE: To report a rare case of Sjögren's reticular retinal dystrophy. CASE SUMMARY: A 54-year-old male presented with blurred vision and metamorphopsia in both eyes since a few years prior to his initial visit. There was a bilateral reticular network of yellow deposits throughout the posterior pole on fundus examination, which was hyperautofluorescent in fundus autofluorescence photographs. The pigment alterations were more visible with fluorescein angiography, which showed hypofluorescent lesions with hyperfluorescent borders. Spectral-domain optical coherence tomography showed elevations of the outer retina associated with the presence of subretinal hyperreflective material. Based on the conclusive correlation with clinical features, we diagnosed Sjögren's reticular retinal dystrophy. CONCLUSIONS: Sjögren's reticular retinal dystrophy is characterized by its specific pigment changes at the level of clinical manifestations and the retinal pigment epithelium. In cases of Sjögren's reticular retinal dystrophy, close monitoring is required because it has a lifetime risk of choroidal neovascularization.
