Abstract Background/Objectives To re-evaluate diabetic papillopathy using optical coherence tomography (OCT) for quantitative analysis of the peripapillary retinal nerve fibre layer (pRNFL), macular ganglion cell layer (mGCL) and inner nuclear layer (mINL) thickness. Subjects/Methods In this retrospective observational case series between June 2008 and July 2019 at Moorfields Eye hospital, 24 eyes of 22 patients with diabetes and optic disc swelling with confirmed diagnosis of NAION or diabetic papillopathy by neuro-ophthalmological assessment were included for evaluation of the pRNFL, mGCL and mINL thicknesses after resolution of optic disc swelling. Results The mean age of included patients was 56.5 (standard deviation (SD) ± 14.85) years with a mean follow-up duration of 216 days. Thinning of pRNFL (mean: 66.26, SD ± 31.80 µm) and mGCL (mean volume: 0.27 mm3, SD ± 0.09) were observed in either group during follow-up, the mINL volume showed no thinning with 0.39 ± 0.05 mm3. The mean decrease in visual acuity was 4.13 (SD ± 14.27) ETDRS letters with a strong correlation between mGCL thickness and visual acuity (rho 0.74, p < 0.001). Conclusion After resolution of acute optic disc swelling, atrophy of pRNFL and mGCL became apparent in all cases of diabetic papillopathy and diabetic NAION, with preservation of mINL volumes. Analysis of OCT did not provide a clear diagnostic distinction between both entities. We suggest a diagnostic overlay with the degree of pRNFL and mGCL atrophy of prognostic relevance for poor visual acuity independent of the semantics of terminology.

Purpose: To describe the findings of four patients (four eyes) with optic disc melanocytoma (ODM), using multimodal imaging. Methods: Retrospective case series. Results: On ocular ultrasonography ODMs appeared as hyperechogenic lesions with moderate-to-high internal reflectivity. On blue-light fundus autofluorescence, ODMs showed total hypoautofluorescence, while, on infrared reflectance images appeared as bright and well-marginated lesions. MultiColor composite images showed reddish-brown lesions with well-defined margins. Swept-source optical coherence tomography revealed elevated lesions covering the optic disc with an irregular hyperreflective surface, dishomogeneous internal structure with hyperreflective dots, and posterior shadowing. In all cases optical coherence tomography angiography detected intratumoral blood vessels which were not detectable with fluorescein angiography. Conclusion: Multimodal imaging in ODM might be useful both at presentation, increasing the diagnostic accuracy, and at follow-up, providing helpful details, that can help to rule out the possibility of malignant transformation and other ocular complications.

Purpose.To evaluate daily spectral-domain optical coherence tomography (SD-OCT) changes in naive-treatment patients with diagnosis of exudative age-related macular degeneration (AMD) treated with intravitreous bevacizumab (1.25 mg), during a 30-day follow-up period.Methods.In prospective, interventional study, SD-OCT was performed daily for 30 days after the first intravitreal injection. The baseline, initial-decrease, minimal, and final central retinal thicknesses (CRTs) were assessed.Results.Nine eyes of nine patients with neovascular AMD were enrolled. The mean baseline CRT was625.3±182.5 μm, and the mean final CRT was383.4±163.0 μm (mean difference,206.1±167.6 μm), a difference that reached significance (P=0.006). After the first injection, the initial decrease in the CRT was seen as an average of one day after injection (mean CRT,503.6±189.10 μm;P=0.0431). The speed of the reduction in the CRT tended to decrease by day 17. The mean CRT was336.5±105.44 μm and the mean minimal CRT on day 30 was320.75±96.38 μm.Conclusion.The CRT decreased early after the first injection. We observed a tendency for reductions in the speed with which the CRT decreased by day 17 after the first injection, which may affect retreatment regime.

Purpose: To assess morphological optic disc dimensions using spectral-domain optical coherence tomography (OCT) in a Nigerian population. Materials and method: Good quality SD-OCT scans of the optic disc of 147 eyes of 88 participants were selected, enrolled, and retrospectively reviewed. All subjects had optic nerve head and retinal nerve fibre layer OCT imaging, as well as analysis, done using the Topcon 3D OCT-1 Maestro®. The age, sex, and some OCT-generated optic disc dimensions namely disc area (DA), vertical disc diameter (VDD), horizontal disc diameter (HDD) were retrieved from the database and analyzed. Results: The mean age of the study subjects was 52.6±20.9 years with a range of 8–90 years; male to female ratio was 1:1.3. The right eye and left eye accounted for 75 and 72 of the 147 scans respectively. The mean DA, VDD, and HDD were 2.54 ± 0.48 mm2, 1926.5 ± 189.6 μm and 1673.9 ± 173.9 μm, respectively. Males had significantly larger DA than females (2.56 ± 0.53 mm2 vs 2.51 ± 0.44 mm2, p = 0.043). The mean DA and VDD of eyes of subjects aged 21–40 years were significantly higher compared to subjects aged 60 years and more ( p = 0.008 and 0.001, respectively). Conclusion: The mean optic disc area and diameters are larger than those reported in similar studies involving blacks and other races. The mean disc area reduces with increasing age.

Aim. To investigate the clinical features of solar maculopathy in a long run by optical coherence tomography. Methods. 31 patients (40 eyes) complaining on scotoma appeared after sun gazing without protection were referred to an advisory clinic of Republican Clinical Hospital of Ophtalmology, Kazan. The mean age of patients was 25.2 years, mean visual acuity - 0.72. In addition to the standard examinations, all patients underwent optical coherence tomography. The patients were followed up for up to 5 years. The examinations were performed before the treatment initiation and repeated on the 15th, 30th and 90th day after the treatment completion. 7 patients (8 eyes) were followed up for 5 years. Results. According to the results of optical coherence tomography, focal retinal edema was found in 9 patients (18 eyes) at the first week. Patients received antioedematic drugs and antioxidants. According to the results of optical coherence tomography a lamellar defect has been formed in fovea centralis on 15th day of treatment. Mean visual acuity improved to 0.78. On 30th and 90th days of treatment, lamellar defect persisted, visual acuity remained unchanged. After 5 years, 7 patients (8 eyes) were re-examined. The mean visual acuity was 0.78, the lamellar defect was still observed by optical coherence tomography. No macular degenerative and dystrophic changes were observed in followed up patients. Conclusion. Sunlight causes permanent damage of the retina. In the first week after the sunburn, marked focal retinal edema in the foveolar area was observed on the tomography, with further formation of a lamellar defect that was not accompanied by degenerative changes in the long-term period. Optical coherence tomography is an informative method of diagnosing solar maculopathy.

IntroductionOptic neuritis (ON) results in acute loss of vision with pain on eye movement. It may be the first manifestation of multiple sclerosis (MS) and usually follows a resolving course. Here we describe five patients with MS who developed severe unilateral ON resulting in persistent visual loss without significant resolution.MethodsA retrospective clinical review of five cases identified from a database of 550 patients with MS.ResultsAll patients were female and the mean age was 30 years at onset (range 25–40). All patients had no light perception at diagnosis, and received treatment with high dose intravenous methylprednisolone. Two patients also had plasma exchange. All of the patients were subsequently treated with immunomodulatory therapy. The patients were followed for a mean period of 13.3 years (range 2 months to 31 years). None of the patients had significant improvement in their visual acuity, with most achieving vision of 6/60. The mean retinal nerve fibre layer thickness was 66.33 microns (range 46–98 microns) in the affected eye, compared to 86.7 microns (69–105 microns) in the unaffected eye. All patients were aquaporin-4 antibody negative and oligoclonal band positive, with the MRI brain and spine being diagnostic for MS. Interestingly, none of the patients developed significant symptoms in the contralateral eye with vision of 6/5. All patients had an EDSS score of 4.0 predominantly due to visual impairment.ConclusionSevere unilateral ON is rarely seen in MS. This case series highlights a phenotypically distinct group of female MS patients with severe unilateral ON, and no improvement in visual acuity after prolonged follow-up and despite treatment with steroids and potent immune therapies. In such patients, where the diagnosis of MS is confirmed by MRI and CSF analysis, the patient might be reassured that visual loss in the fellow eye is unlikely.References. Wilhelm H, Schabet M.

Purpose: To report outcomes of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) stuffing technique in patients with optic disc pit associated maculopathy (ODP-M). Methods: Data including best-corrected visual acuity (BCVA), central macular thickness (CMT), foveal center point thickness (FCP), and maximum height of fluid (max_fluid) (intraretinal or subretinal) were collected from the medical records of the patients. Results: Six eyes of six patients with a mean age of 28.0 ± 17.68 years (range: 9–53 year) underwent PPV + ILM plug surgery. The mean follow-up duration was 25.62 ± 26.11 months (range: 11.80–78.00 month) duration. The mean BCVA increased from 1.25 ± 1.04 logMAR (20/355, Snellen equivalent) to 0.86 ± 1.09 logMAR (20/144, Snellen equivalent) at last follow-up ( p = 0.043). Compared to baseline, CMT, FCP, and max_fluid significantly decreased at all visits after the surgery ( p < 0.05 for all visits). At last follow-up, 66.6% of the eyes (four eyes) showed complete resolution of fluid at a mean of 5.25 ± 4.99 months (range: 1–12 months) after the surgery. Conclusion: PPV with ILM plug seemed to be an effective surgical technique in ODP-M. Studies with longer follow-up and higher number of patients are needed to confirm our results.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Background/Aims. This study evaluates changes of flow and structure of diabetic retinal neovascularization (NV) treated with intravitreal antivascular endothelial growth factor (VEGF) agents using optical coherence tomography angiography (OCTA). With OCTA, retinal blood vessels are visualized at high resolution to separately look at flow and structure information without the need for dye injection. We introduce a new measurement method including and combining information of flow and structure. Methods. Retrospective observational case series. Patients with proliferative diabetic retinopathy (PDR) were treated with intravitreal antiVEGF injections. Retinal NV were repeatedly imaged using swept-source OCTA (Zeiss PlexElite 9000) at baseline, after initial treatment block with 3-4 monthly injections, and during a follow-up period of up to 51 weeks. Change of size and flow density of the structural and angio area of NV was assessed. Results. Nine NV in eight eyes of five patients were analyzed with a median follow-up time of 45 weeks. After the initial treatment block, en face structural area regressed, 18.7% ± 39.0% (95% CI 44.2–6.8%, p = 0.26 ), and en face angio area regressed, 51.9% ± 29.5% (95% CI 32.6 to 71.2%, p = 0.007 ). Flow density within the en face structural area decreased by 33% ± 19.2% (95% CI 20.5–45.5%, p = 0.0077 ). Flow density within the en face angio area decreased by mean 17.9% ± 25.2% (95% CI 1.4–34.4%, p = 0.066 ). In two fellow eyes, NV recurrence could be observed before the onset of vitreous bleeding in one. Conclusion. Our study introduces a new quantitative measurement for NV in PDR, combining structure and flow measurement. The structure area remained after treatment, while its flow density and angio area regressed. We propose this measurement method as a more physiological and possibly more comparable metrics.
