Background: Intrastromal corneal ring segment (ICRS) implantation is one of the treatment options of keratoconus. This study is aiming to evaluate safety and effectivness of ICRS implantation at Al-Dharan Eye Specialist Hospital.Methods: This study is a descriptive retrospective case series study. The target population of this study is patients diagnosed with corneal ectasia who underwent ICRS implantation in Al-Dharan Eye Specialist Hospital, Al-Dharan, Saudi Arabia. Preoperative and postoperative data about uncorrected visual acuity (UCVA), best spectacle–corrected visual acuity (BSCVA), manifest refraction, keratometry, applanation tonometry, corneal topography, and slit-lamp biomicroscopy and indirect ophthalmoscopy were retrieved from medical records of department of Medical Archive. Paired students t-test was used to compare preoperative and postoperative means of study variables.Results: The total number of recruited patients in this study was 57 patients where 62% of them were males. Sixty-six treated eyes were included in this study where no intra-operative complications were recorded. Upon comparing the mean preoperative data to the mean postoperative data at three months, six months and one year intervals, an overall improvement in the measured outcomes was witnessed. UCVA, BSCVA, and keratometric readings exhibited a statistically significant improvement when comparing preoperative with one-year postoperative findings (p<0.001).Conclusions: The findings of this study indicate that ICRS implantation is a safe and effective treatment for keratoconus.

Importance: This study shows that a newer long-arc length intrastromal corneal ring segment is efficient and safe for keratoconus treatment. Background: To evaluate visual, tomographic results and complications of a 320-degree intrastromal corneal ring segment implantation with the femtosecond laser for keratoconus treatment. Design: A prospective, nonrandomized, and interventional study. Participants: A total of 34 eyes of 31 patients diagnosed with keratoconus were enrolled. Methods: Patients were divided into two groups based on the strategy used for 320-degree intrastromal corneal ring segment thickness selection. In one group, this selection was based on spherical equivalent (SE group) and in the other on the mean asphericity (Q group). The uncorrected and corrected distance visual acuities, spherical equivalent, K1, K2, Km, Kmax, and mean asphericity ( Q) on corneal tomography were evaluated preoperatively and at 3 and 6 months postoperatively. For astigmatism improvement, we analyzed the corneal tomographic vectorial astigmatism change preoperatively and at 6 months postoperatively. The mean follow-up period was 6.63 ± 0.96 months. Results: The mean uncorrected distance visual acuity and corrected distance visual acuity improved with a significant spherical equivalent improvement ( p < 0.05), with no differences between the 320-degree intrastromal corneal ring segment groups. All corneal tomographic parameters improved significantly ( p < 0.05) between the preoperative and postoperative intervals, with a significant better performance when we used spherical equivalent for the 320-degree intrastromal corneal ring segment thickness selection. Finally, the mean vectorial corneal tomographic astigmatism significantly improved after 6 months, again with no differences between groups. Conclusion: This study suggests that implanting a 320-degree intrastromal corneal ring segment is a safe and effective procedure for treating patients with keratoconus. It also suggests that for thickness selection spherical equivalent is the better strategy.

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.

Purpose: To assess the indications and visual outcome of eyes undergoing posterior iris fixated intraocular lens (IFIOL) implantation for aphakia, to identify reasons for poor visual outcome, and report occurrence of complications. Methods: In this retrospective case series study, all cases of posterior IFIOL fixation performed over a 30-month period were identified retrospectively. Preoperative and postoperative evaluations comprised objective and subjective refraction, best corrected visual acuity (BCVA), slit lamp biomicroscopy, applanation tonometry, and dilated fundus examination. Results: Fifty-six eyes of 56 patients were analyzed. Mean age was 60.55 ± 17.2 years. The most common indication for IFIOL implantation was surgical aphakia following complicated cataract surgery (n = 33; 58.9%) followed by trauma (n = 10; 17.9%), dropped nucleus/IOL during primary surgery (n = 6; 10.7%), and subluxated/dislocated lens-induced glaucomas (n = 5; 8.9%). BCVA better than or equal to their preoperative BCVA was achieved in 96.43% patients. The surgical aphakia and paediatric/adolescent groups had the best visual results while the dropped nucleus/IOL group and subluxated lens-induced glaucoma groups fared poorly. On the long-term follow-up visit, the most common complication noted was pigment dusting on the corneal endothelium (65.7%). Conclusion: The long-term results suggest that posterior IFIOL implantation is a safe and effective method for correction of aphakia and can be used for a wide range of indications in eyes without adequate capsule support. It may be considered an easier and faster alternative with minimal manipulation to anterior segment structures in paediatric and post-traumatic aphakic eyes.

Abstract Purpose: To evaluate the anatomical effects of implantable phakic contact lens (IPCL) (Care Group, India) on anterior segment and its visual outcomes .Patients and methods: In a prospective interventional case series study, 60 highly myopic eyes of 32 patients were subjected to IPCL implantation in the Ophthalmology Department of Minia University Hospital, Egypt from January 2019 to June 2021. All patients had complete ophthalmic examination and were followed up for 1 year. Pentacam was used for preoperative and postoperative estimation of anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV) and IPCL vault in the 1st, 3rd, and 12th months. Assessment of corneal endothelium was done using specular microscope preoperatively and after 12 months. Preoperative and postoperative refraction and visual acuity were measured. Results: There was a statistically significant decrease in ACD, ACA, and ACV. There was no significant difference between preoperative and postoperative mean intraocular pressure (IOP) by the 12th month (P=0.163). The mean preoperative endothelial cell count (ECD) was significantly reduced from 2929.3±248 cells/mm2 to 2737.9±303 cells/mm2 at the 12th month (P<0.001). with a statistically highly significant improvement of mean Log Mar uncorrected visual acuity (UCVA) from 1.48±0.19 preoperatively to 0.46±0.11 by the end of follow up (P<0.001) with insignificant difference between preoperative best corrected visual acuity (BCVA) and postoperative UCVA (P=0.209). In the 12th month, the mean vault was 240±540 μm. No sight threatening complications occurred.Conclusion: Although IPCL induced anatomical changes, it was safe and effective for correction of high myopia.

BackgroundCorneal neurotisation is a rapidly evolving procedure treating neurotrophic keratopathy. The variety of surgical techniques used and corresponding outcomes after corneal neurotisation are not well understood. This study describes the techniques and outcomes in the largest case series of corneal neurotisation using processed nerve allografts to date.MethodsThis is a retrospective case series of patients who underwent corneal neurotisation with human cadaveric processed nerve allografts. All patients had preoperative and postoperative description of best corrected visual acuity and measurement of corneal sensation. Comparative studies after stratification of techniques were performed.ResultsA total of 17 patients were identified. The cause of corneal anaesthesia was prior infection in eight cases, trigeminal nerve palsy in eight cases and ocular trauma in one case. There were no intraoperative or postoperative complications. Following neurotisation surgery, the time to first gain of corneal sensation and maximal gain of sensation occurred at a mean of 3.7 months (range 1–8 months) and 6.6 months (range 3–15 months), respectively. The mean preoperative and postoperative corneal sensation as measured by Cochet-Bonnet aesthesiometry was 0.36 cm (range 0–3.2 cm) and 4.42 cm (range 0–6 cm), respectively (p<0.01). Visual acuity was unchanged after neurotisation. There were no statistical differences in outcomes based on end-to-end versus end-to-side coaptations, donor nerve selection or laterality of donor nerve.ConclusionCorneal neurotisation with processed nerve allografts is a safe and effective procedure. This study provides further evidence for the use of processed nerve allografts for corneal neurotisation.

Abstract Background and Aims Idiopathic retroperitoneal fibrosis (IRF) is a rare disease characterized by fibroinflammatory periaortic tissue that affects the ureters, causing obstructive nephropathy and impairment of renal function. Findings strongly suggest an autoimmune etiology. Medical treatment includes immunosuppressive drugs, but the optimal treatment has not been established. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) represent markers of active inflammation in the early phase of the disease, and hence could be sensitive predictors of the treatment response. Method This retrospective case series study includes patients with IRF treated with two different protocols: corticosteroids in combination with mycophenolate mofetil (MMF) and corticosteroids combined with azathioprine (AZA). The total number of 28 patients (13 in the first group and 15 in the second group) were treated and followed in the Clinic of nephrology in Military Medical Academy. Results At presentation 92.3% of patients had elevated levels of ESR and CRP, and 67.8% of them had acute renal insufficiency. Systemic symptoms resolved after four weeks in all patients. The kidney function improved significantly in both groups after first moth of treatment, although the creatinine level was higher in the MMF group because of the disease recurrence in 23% of the patients. In MMF group was observed faster reduction in the periaortic mass after six months and 53.8% of patients achieve 100% of the mass reduction at the end of the treatment while 33.3% in AZA group. The levels of ESR and CRP after one month of treatment in AZA group correlated with the fibrotic mass reduction after six months and after one year. In MMF group, only the CRP level after one month correlated with the fibrotic mass reduction achieved after one year. Conclusion MMF had more rapid and complete effect in hydrnephrosis withdrawal and total reduction of the fibrotic tissue, comparing with AZA whose effect was slower and without complete mass reduction. CRP strongly correlated with the remission of the disease in both therapeutic protocols.

Purpose: To compare VA outcomes in patients with advanced keratoconus wearing SCL or after ICRS or DALK. In addition, determine the percentage of complimentary treatments after ICRS and DALK, and which of these was fitting a SCL, and final visual acuity (f-VA) results. Methods: Retrospective case series analyzed 55 eyes with advanced keratoconus fitted with SCL, or after ICRS or a DALK between 2010 and 2018. The variables analyzed were sex, age, UDVA, CDVA, SEQ, K-readings, and f-VA after complimentary treatments. Results: Twenty-eight eyes underwent a DALK, 14 were fitted with a SCL, and other 13 underwent ICRS insertion. Patients after DALK and after ICRS showed statistically significant improvement in UDVA and CDVA after surgery, with no difference between these groups. Patients fitted with SCL showed statistically higher CDVA improvement when compared to ICRS. After DALK and ICRS, respectively, nine eyes (32.14%) and seven eyes (53.85%) were fitted with SCL. Comparison between f-VA with SCL in three groups showed that the best result was achieved in DALK + SCL, with statistically significant difference to only SCL. Conclusion: We showed that the CDVA of eyes fitted with SCL without any surgical treatment was statistically better than CDVA of eyes after ICRS insertion. After DALK and ICRS insertion, many patients needed a complimentary treatment to improve CDVA. The most chosen treatment was fitting a SCL. After this, all eyes showed statistically significant improvement in f-VA, with statistically better results for DALK + SCL when compared to SCL fitted in advanced keratoconus without any surgical treatment.

Abstract Background: To evaluate the efficacy and safety of subconjunctival triamcinolone acetonide (TA) injections for treating uveitic macular edema (UME). Methods: This retrospective case series study included patients with UME who received subconjunctival TA injections with a minimum follow-up period of 6 months. The main outcome was central macular thickness. The secondary outcomes included the best corrected visual acuity, recurrence rate and intraocular pressure. Results: In total, 68 patients (83 eyes) were enrolled in this study. The mean CMT decreased from 456.9 ± 171.1 μm at baseline to 324 ± 175.9 μm, 305.6 μm ± 147.7 μm, 331.8 ± 154.3 μm and 281.1 ± 147.6 μm at 1, 2, 3 and 6 months postinjection, respectively (all P < 0.01). A total of 21/83 eyes exhibited elevated IOPs, which was controlled with topical IOP-lowering agents in 14 eyes, whereas 7 eyes got subconjunctival TA deposit surgically removed. Conclusion: subconjunctival TA injections appear to be safe and effective for UME.Key Words: Triamcinolone acetonide; subconjunctival injection; uveitis; macular edema

Background: Uncontrollable bleeding during thoracic surgery has been a challenging problem faced by surgeons. The aim of this study was to clarify the usefulness of pleural packing as a good alternative to control hemorrhage and to deduce the common point between those patients.Methods: This was a retrospective case series study of eight patients who underwent thoracic surgery with uncontrollable intrathoracic haemorrhage and shock which required intrathoracic packing from January 2014 to December 2019.Results: During the study period, eight patients underwent thoracic surgery with uncontrollable intrathoracic haemorrhage and needed packing.  Successful hemostasis was achieved in all cases after pleural packing. The mean age was 58.5 years and six patients were males. The common point was the history of pulmonary tuberculosis which was with invasive pulmonary aspergillosis for two patients. Incision was a posterolateral thoracotomy in all cases and six patients required pulmonary resection (five lobectomy and one bilobectomy), one patient required decortication, and one had tumorectomy of a paragonglioma located in the Barety’s space. The unpacking took place right after 48 hours. An arrest of the bleeding was noticed in all the remaining patients. The mean time of the mechanical ventilation was 11 days. Complications included atelectasis and infectious pneumonitis. We noted one case of death.Conclusions: Intrathoracic packing may be an effective and feasible technique in managing uncontrollable post-operative hemorrhage when the life of patients is in danger. This technique should always be considered for patients with tuberculosis history.
