Abstract Background and purpose Idiopathic multifocal choroiditis (MFC) is part of the group of choriocapillaritis entities. The clinical definition of the disease has evolved with time. The aim of this article was to undertake a review on MFC, on its present-day appraisal and nomenclature and we also report a series of patients with emphasis on the clinical presentation and the importance of vigorous immunosuppressive management. Methods A review of the literature and a retrospective case series study which was performed in the Centre for Ophthalmic Specialised care (COS), Lausanne, Switzerland. Patients diagnosed from 1994 to 2020 with idiopathic multifocal choroiditis (MFC) treated with multiple immunosuppressants were included. Exclusion criteria were insufficient follow up and cases not treated with vigorous immunosuppressive therapy. Imaging analysis included spectral domain optical coherence tomography (SD-OCT) / enhanced depth imaging OCT (EDI-OCT), OCT angiography (OCT-A). Fluorescein and Indocyanine angiography (FA, ICGA) before and after the instauration of treatment. Best corrected visual acuity (BCVA), intraocular pressure (IOP), routine ocular examination, laser flare photometry (LFP) were performed at presentation and follow-up. Immunosuppression comprised at minimum two among the following agents: prednisone, cyclosporine, azathioprine, mycophenolic acid or infliximab. Mean duration of therapy was calculated. Results 26 (52 eyes) of 2102 new patients (1.24%) were diagnosed with MFC. 25 (96%) patients were female and 1 (4%) was male. 43/52 (82%) eyes were myopic with a mean dioptre of − 5.87 ± 2.94, six (12%) eyes were hypermetropic with mean dioptres 2.0 ± 2.68 and three (6%) were emmetropic. 14/52 (27%) eyes had at least 1 anti-VEGF injection because of choroidal neovascularisation (CNVs), 1 eye had a phototherapy laser and 37/52 (71%) had no complication of CNVs during the follow-up. 5/26 (19%) fulfilled the inclusion criteria for our study. Mean age was 26.4 ± 9.3 years. Snellen best corrected visual acuity (BCVA) at presentation was 0.955+/-0.26. Mean follow up was 84+/-55 months. LFP at presentation was 6.34 ± 2.94 ph/ms. None of four patients with prolonged treatment and prolonged follow-up showed disease activity. One patient still under therapy after 4 months’ follow-up still showed an active neovascular membrane. Conclusion Treatment with multiple immunosuppressive agents was shown to stop the progression of the disease.

Purpose. To evaluate visual results of phacoemulsification in eyes with neovascular age-related macular degeneration (AMD) treated with anti–vascular endothelial growth factor (VEGF) intravitreal injections. Methods. This retrospective noncomparative interventional case-series study assessed best-corrected visual acuity (BCVA) at 4 timepoints: 1) baseline, immediately before first anti-VEGF injection; 2) preoperative, immediately before phacoemulsification; 3) postoperative, 1 month after phacoemulsification; 4) endpoint, at the last visit. Anti-VEGF retreatment regimen was based only on optical coherence tomography. The median time between anti-VEGF injections was evaluated for the time period before and after phacoemulsification. Results. Sixteen eyes of 16 patients were included. The median (range) baseline, preoperative, post-operative, and endpoint BCVA was 0.7 (0.3–1.3), 0.72 (0.4–1.3), 0.5 (0.05–1.0), and 0.36 (0.0–1.0) logMAR, respectively. Best-corrected visual acuity significantly improved after phacoemulsification (mean 3 logMAR lines) and remained stable during follow-up (median 14 months, range 7–28). There was no statistically significant difference in the median time interval between injections before phacoemulsification and after phacoemulsification. Conclusions. Phacoemulsification significantly improved BCVA in patients with choroidal neovascular AMD. This effect persisted during follow-up with no increased need for anti-VEGF injections to keep macula dry.

Aphakic Retinal Detachment

Introduction: Retinal detachment remains one of the most serious complications of cataract surgery. Treatment of this condition has represented a challenge for vitreoretinal surgeons. Scleral buckle (SB) surgery is one of the treatment options in pseudophakic and aphakic retinal detachment (RD). Aims: To find out the anatomical and visual outcome of SB in pseudophakic and aphakic RD. Subjects and methods: Retrospective case series of 46 consecutive eyes of 46 patients with RD (38 pseudophakic and 8 aphakic eyes) that had undergone conventional SB surgery were reviewed from patient files. Postoperative retinal status at 3 weeks, 6 weeks and 3 months were recorded to see the anatomical success rate after retinal reattachment surgery. Best corrected visual acuity (BCVA) at 3 months follow-up was noted. Results: The mean age of the patients was 54.28 ± 13.49 years. Forty eyes (86.9 %) had primary attachment by 6 weeks duration. Five eyes had undergone repeat surgery within a six-week duration (pars plana vitrectomy). Forty patients had follow-up visit to 12 weeks, achieving retinal attachment in 37 eyes (80.5 %). Best corrected visual acuity (BCVA) at 3 months was better than 6/60 in 18 eyes (39.1%), BCVA better or equal to 1/60 but less than 6/60 in 18 eyes (39.1%) and BCVA less than 1/60 in 4 eyes (8.7 %). Conclusion: Conventional scleral buckling has good outcome for pseudophakic and aphakic RD and can be useful for patients in peripheral eye hospitals where patients cannot afford high cost surgeries.

Abstract Purpose: To audit phacoemulsification cataract surgeries performed independently after a short - term training completed in a rural hospital in Kenya, and to benchmark the outcomes against WHO recommendations. Methods: This retrospective case-series study recruited patients who had had phacoemulsification cataract surgery at Sabatia Eye Hospital from January to December 2018. All the surgeries were performed by a single surgeon following a brief training in the same center. Data were collected retrospectively using a detailed questionnaire. Results: Of the one hundred and twenty eyes operated on during this period, one-hundred and sixteen eyes of 86 patients met the inclusion criteria. The mean age was 62 years and the majority of the eyes (83.6%) had vision less than 6/18 preoperatively. Co-morbidities included diabetic retinopathy (3.4%), age-related macular degeneration (2.6%), trauma (1.7%) and glaucoma (0.9%). Surgical complications were not severe enough to affect the final best-corrected visual acuity, unlike the comorbidities that were negatively correlated with visual outcomes (p-value< 0.001). Good outcomes were 81% against a WHO target of 80% for uncorrected visual acuity category, and 96.6% in the best-corrected visual acuity category against a target of 90%. The Royal College of Ophthalmology database of cataract surgery outcomes and the European Registry of Quality Outcomes for cataract and refractive surgery had comparable results. Conclusions: This local training model was based on apprenticeship and skills transfer. It can achieve high-quality visual outcomes meeting WHO recommendations.

Purpose To analyze the tomographically non-affected second eyes of keratoconus patients using the Corvis ST to detect any biomechanical abnormalities or subclinical keratoconus. Methods In this retrospective, single-center, consecutive case series 244 eyes of 122 keratoconus patients were analyzed between November 2020 and February 2021. Fourteen fellow eyes fulfilled the inclusion criteria and showed no clinical or tomographic signs of keratoconus. Main outcome measures included best-corrected visual acuity, tomographic and biomechanical analyses using Scheimpflug imaging: Pentacam and Corvis ST (Oculus, Wetzlar, Germany). Tomographic analyses included anterior and posterior simulated keratometry, K-Max, central corneal thickness, thinnest corneal thickness, Belin/Ambrosio Ectasia Display, and the ABCD grading system. For biomechanical analyses, the corneal biomechanical index (CBI) and tomographic biomechanical index were used. Results The mean best-corrected visual acuity was 0.01 ± 0.10 logMAR. Mean K-Max was 43.79 ± 1.12 D, mean central corneal thickness 529 ± 25 µm, mean thinnest corneal thickness 524 ± 23 µm, and mean Belin/Ambrosio Ectasia Display 1.0 ± 0.32. The mean CBI was 0.30 ± 0.21. Regular CBI values were found in six of 14 patients. The mean tomographic biomechanical index was 0.47 ± 0.22 with regular values observed in only two of 14 patients. No signs of tomographic or biomechanical abnormalities were shown in only one of 14 keratoconus fellow eyes, with regular ABCD, Belin/Ambrosio Ectasia Display, CBI and tomographic biomechanical index values. Conclusions Tomographically normal fellow eyes of keratoconus patients are rare. In these cases, a biomechanical analysis of the cornea may help detect a subclinical keratoconus. The tomographic biomechanical index was the most sensitive index to verify a mild ectasia.

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.

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.

Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Background: Amblyopia is more common in children with high astigmatism, but factors contributing to development of amblyopia and visual outcomes are not fully understood. Objective: To evaluate the effect of amblyopia on the clinical outcomes in children with ⩾1.75 diopter (D) astigmatism. Methods: We reviewed the medical records of children with ⩾1.75 D astigmatism with and without amblyopia (amblyopes group and non-amblyopes group). The mean age, gender, amount and type of ocular deviation, presence of convergence insufficiency (CI), stereopsis, time of initial spectacle use and follow-up time, differences in best-corrected visual acuity (VoD) and spherical equivalent (SE) between eyes were assessed and compared between the groups. Best-corrected visual acuity (BCVA), mean SE, astigmatism measurements were assessed and compared between amblyopic, fellow, and non-amblyopic eyes. Results: The records included 68 eyes of 34 children with amblyopia and 56 eyes of 28 children without amblyopia. The mean age, gender, amount and type of ocular deviation, presence of CI, stereopsis, time of initial spectacle use, follow-up time, and the difference in SE did not differ between groups. In amblyopes, exodeviation was more common and statistically greater in near (33 cm) than at distance (6 m) (p = 0.005). The mean BCVA and astigmatism values were statistically different between amblyopic, fellow, and non-amblyopic eyes. Conclusion: A greater near than distance exodeviation and higher mean astigmatism value were found in amblyopic children with astigmatism.

Purpose To evaluate postoperative safety of femtosecond laser deep anterior lamellar keratoplasty performed with an innovative anvil profile in keratoconus patients. Methods This is a single-center, retrospective cohort study. We reviewed medical records of 89 keratoconus patients that underwent femtosecond laser deep anterior lamellar keratoplasty surgery (46 eyes) and manual deep anterior lamellar keratoplasty (47 eyes). Inclusion criteria required: age > 18 years old, best-corrected visual acuity < 0.3 LogMAR, continuous suture of the graft, postoperative immunomodulant regimen with dexamethasone 0.1% for 6 months and at least 12 months follow-up. Previous eye surgery, hydrops, and other ocular disease were excluded. The main outcome measures were postoperative events: rejections, persistent epithelial defects, and graft failures. Results During the follow-up (20 ± 6 months) graft rejection was diagnosed in 0 of femtosecond laser deep anterior lamellar keratoplasty versus 6 (17%) of manual deep anterior lamellar keratoplasty [ p 0.027], persistent epithelial defect in 0 of femtosecond laser deep anterior lamellar keratoplasty versus in 4 (11%) of manual deep anterior lamellar keratoplasty [ p 0.048] and graft failure occurred in 4 (11%) of manual deep anterior lamellar keratoplasty. The best-corrected visual acuity, after removal of sutures, was better in the femtosecond laser deep anterior lamellar keratoplasty group 0.09 ± 0.08 LogMAR versus 0.16 ± 0.13 LogMAR in manual deep anterior lamellar keratoplasty [ p 0.035] group although refractive spherical equivalent and cylinder, topographic average keratometry and cylinder were similar. Conclusions Anvil-shaped femtosecond laser deep anterior lamellar keratoplasty in keratoconus surgery increases safety and readiness of recovery, decreasing the incidence of corneal rejection, epithelial defects, graft failures, and producing better best-corrected visual acuity after removal of sutures.
