Background: The aim of this study was to evaluate the quantitative morphological changes in lamellar macular holes (LMHs) based on SD-OCT examinations and to assess the correlations among minimal retinal thickness (MRT), reading vision (RV), and best corrected visual acuity (BCVA) over a 36-month follow-up period. Methods: A group of 40 patients (44 eyes) with LMH was evaluated, with an average age of 69.87 (SD = 10.14). The quantitative parameters monitored in the follow-up period (at 0, 3, 6, 12, 18, 24, 30, and 36 months) were tested for normality of distribution by Shapiro–Wilk and Kolmogorov–Smirnov tests. Results: The RV and BCVA values were stable, and no significant changes were found at any of the check-ups during the 36-month follow-up period (BCVA p = 0.435 and RV p = 0.0999). The analysis of individual quantitative LMH parameters during the 36-month follow-up period did not demonstrate statistically significant differences: MRT (p = 0.461), Max RT temporal (p = 0.051), Max RT nasal (p = 0.364), inner diameter (ID) (p = 0.089), and outer diameter (OD) (p = 0.985). Conclusions: The observations at 0, 6, 12, 18, 24, 30, and 36 months revealed moderate and significant correlations between RV and MRT. No significant correlation between BCVA and MRT was observed.

Purpose:  To find the effectiveness of sub-threshold (810nm) micropulse diode laser treatment (SMT) in chronic central serous retinopathy (CSR). Study Design:  Interventional case series. Place and Duration of Study:  Layton Rahmatulla benevolent trust eye hospital, from April 2019 to July 2020. Methods:  The patients of chronic CSR (≥ 6 months) participated in the study. We used Spectral Domain Optical coherence tomography (SD-OCT) to record baseline central retinal thickness (CT). Best corrected visual acuity (BCVA) was recorded with Snellen’s chart and converted to Log MAR for statistical analysis. All patients underwent treatment with sub-threshold laser (810nm) in micropulse mode with 5% duty cycle (DC). Results:  Twenty five eyes with chronic CSR were enrolled in the study. The patients were treated with laser and final assessment was made at 6 months. Mean BCVA at presentation was 0.46 Log MAR ± 0.12 and a mean baseline CT of 362.2 μm ± 32.6µm. At final follow-up there was a mean decrease in CT of 97.2 μm ± 21.8 from the baseline. After treatment mean BCVA was 0.33 Log MAR ± 0.12 and mean CT was 266 μm ± 20.9. Nineteen out of twenty-five eyes (76%) achieved a gain of vision between 1 to 3 lines and gain of 3 lines was achieved in 8% of cases. At the final follow-up there was incomplete resolution of sub retinal fluid in 4 eyes (16%) with no improvement in BCVA. Conclusion:  SMT (810 nm) is an effective and minimally invasive treatment modality for chronic CSR. Key Words:  Sub-Threshold micropulse laser, Central serous retinopathy, Central retinal thickness, sub retinal fluid.

Purpose.To explore the structural progression of X-linked retinoschisis (XLRS) in patients by using spectral-domain optical coherence tomography (SD-OCT).Design.Retrospective, observational study.Methods.Patients who were diagnosed with XLRS by genetic testing underwent comprehensive ophthalmological examinations from December 2014 to October 2016. Each eye was measured by SD-OCT using the same clinical protocol. A correlation between best-corrected visual acuity (VA) and SD-OCT measurements was observed.Results.Six patients demonstrated retinoschisis (12 eyes) and typical foveal cyst-like cavities (10 eyes) on SD-OCT images with a mean logMAR VA of 0.48. The median age was 7.5 years at the initial visit. Their foveal retinal thickness (516.9 μm) and choroid thickness (351.4 μm) decreased at a rate of 38.1 and 7.5 μm, respectively, at the 10.5-month follow-up visit; however, there were no significant differences (P=0.622andP=0.406, resp.). There was no significant correlation between VA, the foveal retinal thickness, and subfoveal choroid thickness.Conclusions.SD-OCT images for XLRS patients during the juvenile period revealed no significant changes in the fundus structure, including the foveal retinal thickness and choroid thickness within one-year follow-up. There was a lack of correlation between VA, foveal retinal thickness, and subfoveal choroid thickness.

Purpose: To compare the efficacy of intravitreal injections (IVI) of ranibizumab (Lucentis®, Novartis, Basel, Switzerland; RAN), aflibercept (Eylea®, Bayer, Leverkusen, Germany; AFL) and dexamethasone implant (Ozurdex®, Allergan, Irvine, California; DXI) in the treatment of naive diabetic macular oedema (DME) during a 12-month follow-up, in real life. Methods: Nineteen eyes treated with RAN, 20 with AFL and 21 with DXI were analysed from inclusion up to 12 months (M12) with intermediate analysis at M6. Best corrected visual acuity (BCVA), fundus and central retinal thickness (CRT) using spectral-domain optical coherence tomography (SD-OCT; Spectralis/HRA, Heidelberg Engineering, Germany) were performed at inclusion, M3, M6 and M12. Results: BCVA improved until 67.9 letters ±13.3 SD (+5.5 letters) at M6 and 69.6 letters ±12 SD (+7.2 letters) at 12 months for RAN group ( p = 0.036). For the AFL group it improved until 63.6 letters ±15.2 SD (+6.6 letters) at M6 and 67.5 letters ±12.2 SD (+8.5 letters) at 12 months ( p = 0.014). Lastly DXI group improved by 66.9 letters ±15.1 SD (+7.9 letters) at M6 and 68.4 letters ±11.2 SD (+9.4 letters) at 12 months ( p = 0.0023). CRT decreased by 124.4 µm at M6 and 99.3 µm at M12 in RAN group, 144.3 µm and 101.5 µm in AFL group and finally 95.6 µm and 162.7 µm in DXI group. Conclusion: In summary, these three drugs provide an efficient treatment option with an acceptable benefit-risk ratio for the treatment of naive patients with DME, whether on BCVA or CRT on the first year of treatment.

Postmortem pathological examinations, animal studies, and anecdotal reports suggest that coronavirus disease 2019 (COVID-19) could potentially affect intraocular tissue. However, published evidence is scarce and conflicting. In our study, we screened 100 eyes of 50 patients hospitalized for COVID-19. Relevant medical and ophthalmological history was assessed as well as symptoms, laboratory results, specific treatments, clinical course, and outcome. Ophthalmic exams including assessment of best corrected visual acuity (BCVA), intraocular pressure (IOP), color perception, ocular motility, ophthalmoscopy as well as optical coherence tomography (OCT) of the macula and the optic disc was performed at hospital admission and 29 to 192 days later. Of the 50 patients included, 14 (28%) were female. Median age was 64.5 (range 29–90) years. COVID-19 severity was mild in 15 (30%), severe in 30 (60%), and critical in five cases (10%). At baseline, median BCVA was 0.1 (0–1.8) Logarithm of the Minimum Angle of Resolution (LogMAR) and median IOP was 16 (8–22) mmHg. At follow-up, no relevant changes in BCVA and IOP were documented. No signs of active intraocular inflammation or optic nerve affection were found and OCT findings were widely stable during the observation period. Our findings suggest that COVID-19 does not regularly affect intraocular tissue.

Keratoconus is a progressive degenerative disease in which, due to the weakening of the biomechanical strength of the cornea, its cone-shaped deformation occurs, leading to the development of induced myopia and astigmatism, as well as to a decrease in corrected visual acuity. Treatment of this disease consists in achieving stabilization of the process by strengthening the structure of the cornea, as well as in correcting refractive disorders caused by corneal deformation. Purpose. The purpose is to evaluate the effectiveness of correction of refractive disorders by implanting a closed MyoRing ring in the corneal stroma of patients with keratoconus. Material and methods. The data of 98 MyoRing implantation operations using CISIS technology using the PoketMaker ultraceratom for stage 3-4 keratoconus were analyzed. The observation period is up to 9 years. The initial myopia averaged -9.23 D ±3.82, astigmatism-6.13 ±2.51. Results. Stabilization of the refractive effect occurred usually within 3-6 months after surgery. On average, the following correction of refractive disorders was achieved: myopia-8.14 D ± 2.67 and astigmatism-4.28 D ± 2.12. Keratometry indicators also in most cases stabilized within 3-6 months after surgery and remained unchanged throughout the entire follow-up period. Conclusions. Implantation of a closed MyoRing ring in keratoconus makes it possible to significantly correct refractive disorders and prevents further progression of the disease. Key words: keratoconus, MyoRing, SISI, ring implantation in keratoconus.

Purpose: To analyze the anatomical and functional outcomes in patients with choroidal neovascularization (CNV) secondary to pathological myopia (PM). Methods: Retrospective review of the medical records of 40 patients with CNV secondary to PM treated exclusively with intravitreal ranibizumab 0.5 mg and at least 24 months of follow-up. The initial dose comprised 1 or 3 monthly injections followed by a pro re nata regimen. Best-corrected visual acuity (BCVA), central retinal thickness (CRT) measured with spectral domain optical coherence tomography (OCT), and ocular and systemic adverse event were recorded. Results: Mean patient age was 62.5 ± 12.5 years. The mean spherical equivalent refractive error was −12.3 ± 6.9 diopters, and a single intravitreal injection was initially performed in 72.5% of cases. Mean baseline BCVA was 0.33 ± 0.20 logMAR (Snellen equivalent, 20/60), and mean CRT by OCT was 340.65 ± 80 µm. Both BCVA and OCT revealed significant improvement compared to baseline at all established cutoff points ( P < .001). Final BCVA was 0.50 ± 0.3 logMAR (Snellen, 20/40), and final CRT was 255.69 ± 47.7 µm ( P < .001). The mean number of ranibizumab injections was 2.75 ± 1.97. No cases of endophthalmitis or retinal detachments were reported, and no serious adverse systemic events were identified. Conclusion: Excellent anatomical and functional outcomes were obtained after treatment with intravitreal ranibizumab for CNV secondary to PM.

Purpose: to study the efficiency of Bowman layer transplantation (BLT) in corneal stroma for the treatment of progressive keratoconus (KC).Material and methods. 30 patients (30 eyes) with progressive KC stages III to IV (according to Amsler — Krumeich classification), underwent BLT into a mid-stromal pocket. At the time of surgery, the patients were 14 to 37 (averagely 26.6 ± 6.2 years). Before and after the surgery, the maximum keratometry index (Kmax) and the corneal thinnest point (CTP) values were determined. Also, we evaluated visual acuity before and after surgery in scleral contact lenses, endothelial cells density (ECD) and the depth of graft location. The indication for surgery was the refusal of corneal transplantation, progression of KC, contraindications for ultraviolet crosslinking or implantation of intracorneal ring segments based on the CTP and Kmax values. The follow-up continued 6 to 36 months (averagely, 26.6 ± 6.0 months).Results. Throughout the observation period, no intra or postoperative complications associated with BLT or deterioration of CTP, Kmax or best corrected visual acuity (BCVA) in scleral lenses were noted.Conclusions. Kmax, CTP and ECD values remaining stable during the follow-up is the evidence of a stabilizing BLT effect on the KC progression. The absence of BCVA decrease in scleral lenses indicates a functional safety of BLT.

Purpose: To compare the clinical findings and outcomes of vitrectomy for lamellar macular holes (LMH) versus epiretinal membrane foveoschisis (ERMF). Materials and methods: This retrospective study enrolled 36 eyes of 35 patients with a minimum follow-up of 6 months. Spectral domain optical coherence tomography (SD-OCT) parameters and best-corrected visual acuity (BCVA) were analyzed preoperatively and postoperatively. Results: The 19 (52.8%) ERMF and 17 (47.2%) LMH were included. Preoperatively, eyes with LMH were characterized by a lower central foveal thickness (CFT) (102.18 ± 31.44 µm vs 159.37 ± 25.25 µm, p < 0.001) and a greater incidence of outer retinal disruption ( p < 0.001). Primary anatomical success was achieved in 34/36 eyes (94.4%). Preoperative BCVA was better in ERMF (0.16 – IQR 0.09 – logarithm of the minimal angle of resolution (LogMAR) – 20/28 Snellen) than LMH (0.40 – IQR 0.30 – LogMAR, 20/50 Snellen) ( p = 0.008). At 6 months after surgery, BCVA significantly improved in the ERMF group ( p < 0.001), but showed insignificant change in LMH ( p = 0.125). Two cases, both in the LMH group, developed full thickness macular hole after surgery. Conclusion: Eyes with LMH showed visual stabilization after surgery, whereas the eyes in the ERMF group were susceptible to functional improvement. These differences in BCVA outcomes may be the consequence of a higher damage in the outer retina in the LMH group; an accurate SD-OCT examination is a fundamental step when deciding to proceed or not to the surgery.

Purpose: To evaluate the 1-year results of 25-gauge microincision vitrectomy surgery (MIVS25) combined with intraoperative dexamethasone (DEX) implant for persistent diabetic macular edema (DME). Methods: This study enrolled patients who had a history of DME for ≥12 months and underwent MIVS25 and DEX implant injection. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) were assessed postoperatively. Results: Eighteen eyes were included in the analysis. Preoperatively, logMAR BCVA was 0.90 and CRT was 594 µm on average. CRT decreased until the 3-month follow-up visit and tended to increase at 6 months, but stabilized at 12 months with additional treatments in five eyes at 5 months postoperatively. Statistically significant improvement in BCVA was noted 1 month after treatment and at each subsequent follow-up visit (p < 0.001). Conclusion: MIVS25 combined with DEX implant injection might be utilized as an effective and safe alternative treatment for intractable DME.

Objective: Analysis of clinical efficacy and subjective satisfaction of patients with post-thrombotic macular edema after intravitreal administration of Ozurdex (dexamethasone).Methods: Thestudy included 33 patients (33 eyes) aged from 51 to 75 years with post-thrombotic macular retinal edema. The results were assessed before the intravitreal implantation, after one day, after a month, and three months later after the surgery.Results: The central retinal thickness significantly decreased on the first day after the surgery remaining almost the same after one and three months. The average retinal thickness had the similar dynamics. The macular volume reduced by 1.5 times in a day after the surgery. The maximum corrected visual acuity gradually increased over the time, remaining on average at the level of 0.5 diopters after one and three months. The subjective evalua‑ tion of quality of life (according to the VF-14 questionnaire) during the observation period progressively increased reaching 47.1 points by the end of the study.Conclusions: The study findings convincingly indicate the clinical efficacy of the intravitreal administration of dexamethasone and the subjective satisfaction of patients with the quality of treatment both in the early and late postoperative periods.
