Abstract Background: malignant glaucoma after cataract surgery is still one of the serious complications, if not handled properly，it may lead to serious consequences. It is notoriously difficult to treat. 25G vitrectomy was performed to evaluate the safety and efficacy for the treatment of malignant glaucoma in pseudophakia. Methods: This is a retrospective, comparative case series study. A total of 20 eyes of 20 patients with malignant glaucoma after phacoemulsification were analyzed retrospectively in The First Affiliated Hospital Of Anhui Medical University from May 2015 to January 2018. All Medical Data including the best corrected visual acuity (BCVA), Change of intraocular pressure (IOP), the length of eye axis, and the depth of anterior chamber were recorded. SPSS 17.0 statistical software was used for analysis .Before surgery, the best corrected visual acuity (BCVA) was 1.8±0.6. The intraocular pressure was between 18-57mmHg, with an average of 35.2±10.4mmHg.The depth of anterior chamber was between 0.9-1.9mm, with an average of 1.3±0.2mm.The length of eye axis was 19.7-22.5mm,with an average of 20.6±0.5mm.All the patients were accomplished with 25G vitrectomy. Besides, anterior chamber inflammatory reaction and other complications were also observed postoperation. Results: The patients were followed up for 6-12 months with an average of 9 months. BCVA at the last follow up improved to 0.8±0.1, and there was significant difference compared to that before operation (P<0.01).IOP was from 12-19mmHg, an average of 16.1±2.5mmHg, there was significant difference compared to that before operation (t=7.6, p<0.01).Only one patient occurred low IOP (6mmHg) after surgery, IOP returned to normal level (14mmHg) after conservative treatment. No serious complications including corneal endothelium decompensation, intraocular lens (IOL) capture, intraocular hemorrhage, endophthalmitis and uncontrolled IOP were observed. Conclusions: 25G minimally invasive vitrectomy can treat malignant glaucoma after cataract surgery safely and effectively

Objective- To evaluate and compare efficacy and safety of topical Difluprednate ophthalmic emulsion 0.05% with Nepafenac ophthalmic suspension 0.1% in patients of uneventful cataract surgery with respect to postoperative macular thickness and volume. Design- A prospective, single centric, tertiary care centre based, comparative, interventional study from August 2013 to July 2014 Subjects- Total 206 ( Group N=106, Group D=100) patients were followed up who completed their 12 weeks follow up Methodology- Surgery was performed by phacoemulsification technique by clear corneal incision with foldable PCIOL implantation by a single surgeon having 10 years of surgical experience. Post operative patients were divided into 2 groups. Group N were given topical treatment with Nepafenac ophthalmic suspension  0.1% TID starting 24 hours before surgery  and continued post-op 4 weeks. Group D were given Difluprednate ophthalmic emulsion 0.05% QID post surgery for 2 weeks followed by BID for 2 weeks.  Main outcome measures: Postoperative assessment of patients were done on 1st day and on 1st, 8th and12th  weeks  after the surgery for best corrected visual acuity (BCVA) by logMAR, intraocular pressure by Applanation tonometry and macular thickness and volume by SD-OCT. Statistical test used was sample Unpaired and paired ‘t’ test  and statistical analysis was done with SPSS 20.0 ( IBM, USA). Results- There was increase in the measured mean central subfield thickness( CST) at 8 and 12 weeks as compared to 1 week , in both the study groups (P<0.05). On comparing the volume (in mm3) and average thickness (in µm) at 1 week, it was observed that thickness of group N (266.82±25.06 µm) was statistically higher than that of group D (253.14±22.21µm) (P= 0.03). The comparison of best corrected visual acuity (LogMAR) and the intraocular pressure recordings showed no difference between the patients of two studied groups recorded at 1 week and 8 weeks and 12weeks. Conclusion- Both Nepafenac ophthalmic suspension 0.1% and Difluprednate ophthalmic emulsion 0.05% are equally effective in controlling macular thickness change after uneventful cataract surgery.

Glaucoma is a leading cause of blindness. Surgical and pharmacological treatment of glaucoma aims to lower the intraocular pressure (IOP) and preserve visual function. The severe acute res-piratory syndrome coronavirus 2 pandemic has placed a strain on the healthcare system. We aimed to compare the quantity, type of anti-glaucoma surgeries, and the disease stage before and during the coronavirus disease pandemic. We analyzed 362 eyes of 306 patients and 172 eyes of 149 patients from the pre-pandemic and pandemic groups, respectively. The number of an-ti-glaucoma surgeries was halved during the pandemic compared to a similar pre-pandemic pe-riod, with a significant difference in the procedural structures between the two groups (p&lt;0.001). The most common procedures in the pre-pandemic group were Ex-Press implantation (33.7%) and trabeculectomy (31.5%). Within the pandemic group, half of the eyes underwent tra-beculectomy (50.0%), followed by Preserflo microshunt (11.6%). A significant difference in the average IOPs was revealed among patients who qualified for surgery 22.21 &plusmn; 7.83 mmHg in the pre-pandemic group and 25.16 &plusmn; 9.48 mmHg in the pandemic group; p&lt;0.001). There was no significant difference in the best corrected visual acuity between the groups (p=0.263). Glaucoma treatment remained relatively accessible during the pandemic.

Abstract Background: clinically significant macular edema ( CSME) consider as one of the most critical complications of poorly controlled diabetes and it’s the main reason for decreased vision in that kind of patients, we try in this article to find the relation between glycosylated hemoglobin level and the response to bevacizumab injections in people with macular edema   Materials and methods: Ninety-five patients (55 male:40 female) were recruited in this study, all of them had diabetes type2, age of the participants ranging from 42 to 70 years old, Complete ophthalmic examination was done for all the participants including (best-corrected visual acuity), (intraocular pressure) checking, fundus evaluation, and central macular thickness measurement, serum glycosylated hemoglobin (HbA1C) was also measured, Patients were given 0.05ml(1.25mg) of bevacizumab (Avastin)  intravitreally for three successive months, Follow up visit was at 4,8,12 week post-injection. On each follow up detailed examination was done including the( best-corrected visual acuity) examination, (Intraocular pressure), both fundus examination, and OCT of the macula. Results: This study included 111 patients who had type 2 diabetes mellitus who were classified according to HbA1c into two sub-groups, HbA1c ≤ 7 % (n = 45) and HbA1c > 7 % (n = 66) we found no significant difference in mean age and frequency distribution according to gender between study groups (p > 0.05), but, there was a highly significant difference in mean HbA1c % (p < 0.001). when we compare mean OCT and mean VA before and after the intervention in patients who had diabetes mellitus classified according to HbA1c into (HbA1c ≤ 7 % and HbA1c > 7 %) we found that before the intervention, there was no significant difference in mean OCT between study groups (p > 0.05), but after the intervention, there was a reduction in mean OCT and the reduction was more pronounced in the group of HbA1c of less than 7 % (p < 0.001). About visual acuity, we found no significant difference before the intervention and after the intervention, the changes were comparable between both study groups (p > 0.05). Conclusion: intra-vitreal injections of bevacizumab result in anatomical (macular thickness) and functional (vision ) improvement in those patients who had diabetic macular edema and strict glycemic control affecting the outcome of the treatment where strict regulation of glucose level have yield maximum benefit from the given therapy

Aim: The aim of this study is to evaluate the efficacy of pupil cerclage and a new variant of sliding knot technique for repairing traumatic mydriasis. Design: This is a observational case series study. Setting/methods: A series of consecutive patients affected by traumatic permanent mydriasis who underwent pupil cerclage were recruited at the Department of Ophthalmology of the University of Padova, Italy. Best-corrected visual acuity, measured in logarithm of minimum angle of resolution (logMAR), and intraocular pressure at 1, 3, 6, and 12 months were monitored. Postoperative pupil size and anterior chamber angle were measured. Postoperative cystoid macular edema (CME) and glaucoma were evaluated. Results: Twelve patients were recruited. Phakic patients (7) underwent cataract surgery combined with pupil cerclage. Vitrectomy was performed in nine patients. Best-corrected visual acuity improved from 2.9 ± 1.1 logMAR at baseline to 0.3 ± 0.8 logMAR at 12th month. No significant difference between the preoperative and postoperative intraocular pressure was demonstrated. Mean pupil size at 12th month was 2.82 ± 0.5 mm with round shape. Anterior chamber angle mean was 47° ± 4.5°. Six patients developed a CME, and two patients a glaucoma. Conclusion: Pupil cerclage technique reestablishes the pupil with a precise regulation of the pupil size without distortion of its natural round shape. New sliding knot allows surgeon to reduce the risk of iatrogenic iris damage and to make a security permanent knot.

Purpose: To assess tolerability and efficacy following a switch from benzalkonium chloride–latanoprost to preservative-free latanoprost in patients with glaucoma or ocular hypertension. Methods: A total of 140 patients with glaucoma or ocular hypertension controlled with benzalkonium chloride-latanoprost for at least 3 months were switched to treatment with preservative-free latanoprost. Assessments were made on days 15, 45, and 90 (D15, D45, and D90) and included best-corrected visual acuity, intraocular pressure, slit lamp examination, fluorescein staining, tear film break-up time, patient symptom evaluation, and subjective estimation of tolerability. Results: Mean best-corrected visual acuity remained unchanged during the study. Mean intraocular pressure compared with baseline (D0) remained stable throughout the study (D0, 15.9 mmHg (standard deviation = 2.6); D90, 15.3 mmHg (standard deviation = 2.4); p < 0.006). Tear film break-up time improved or remained unchanged relative to baseline in 92% of patients at D45 and in 93% at D90. Moderate-to-severe conjunctival hyperemia was seen in 56.8% of patients at D0, but this figure decreased to 13.7%, 2.2%, and 1.6% at D15, D45, and D90, respectively. Subjective assessment of tolerability (0–10 scale) indicated improvement with change of therapy (mean score: 5.3 (standard deviation = 2.2) at D0 versus 1.9 (standard deviation = 1.7) at D90; p < 0.0001). Conclusion: Preservative-free latanoprost has at least the same intraocular pressure-lowering efficacy as benzalkonium chloride–latanoprost, with a better tolerability profile. This may translate into greater control of treatment and improved quality of life.

Dry Eye Symptoms

Introduction. Dry eye syndrome has become a common problem after ocular surgeries with a significant impact on the quality of life. Many patients, who have undergone cataract surgery, postop?eratively developed dry eye symptoms. Dry eye syndrome is one of the risk factors associated with cataract surgery. Material and Methods. The prospective study included 80 patients. We recorded the self-reported dry eye symptoms, the values of Schirmer test, tear breakup time, and best corrected visual acuity preoperatively, as well as 7 days and 1 month after the surgery. Results. A total of 80 patients were included in the study, 45 (56.2%) females and 35 (43.8%) males. The mean age of patients was 61.5 years (SD ? 6.2, range 57 - 70 years). The best corrected visual acuity at the time of surgery was 0.4 or less in 70 patients (87.5%). Most patients reported a significant improvement in visual acuity after surgery; 68 (85%) eyes achieved a best corrected visual acuity of 0.5 or higher (median 0.7; range 0.5 - 1.0). The mean tear breaking time in cata?ract patients before surgery was 12.4 sec, 7 days after the surgery it was 8.2 sec (p < 0.05) and 1 moth after the surgery 11.1 sec. The majority of patients had mild (47.5%) and moderate (33.75%) Schirmer test values. Dry eye with wetting < 5 mm after 5 minutes was found in 16.2% of patients before cataract surgery; 7 days after the surgery (p < 0.05) it was found in 23.75% of patients and one month after surgery 11.1 sec. A foreign body sensation and watery eye were the most reported symptoms before cataract surgery. Seven days after the surgery foreign body sensation was present in 48.75% and watery eyes in 40% of patients. Conclusion. Significant increase in dry eye symptoms after cataract surgery was found with increasing age. Self reported dry eye problems are more common in patients with lower Schirmer test and best corrected visual acu?ity values before cataract surgery. Patients with concomitant dry eye disease require preoperative and postoperative treatment of dry eye to prevent aggravation of the existing symptoms that may affect the visual outcome after cataract surgery.

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:The purpose of the study was to identify macular edema after cataract surgery in eyes with and without pseudoexfoliation syndrome. The study was a post-hoc analysis of a randomized, double-blind, prospective single-center study. Patients were enrolled between January 2016 and October 2016 as per the national guidelines for the management of cataract in the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland.Methods:One hundred and fifty-six eyes of 149 patients undergoing routine cataract surgery. Postoperatively anti-inflammatory medication was either dexamethasone (N = 78) or diclofenac (N = 78). Spectral domain optical coherence tomography imaging and laser flare meter measurement of the anterior chamber were conducted before surgery and at the control visit 28 days postoperatively.Results:Baseline variables were comparable between eyes with pseudoexfoliation syndrome (N = 32) and those without (N = 124), except for intraocular pressure ( P = 0.002) and glaucoma medication ( P < 0.001). In patients having pseudoexfoliation syndrome, central retinal thickness increase (mean ± standard error of the mean) was 63.3 ± 35.5 μm for dexamethasone and 17.6 ± 5.8 μm for diclofenac, compared to 28.9 ± 8.0 μm ( P = NS) and 6.9 ± 1.3 μm ( P = 0.014) in eyes without pseudoexfoliation syndrome, respectively. Aqueous flare at 28 days was 25.8 ± 5.4 pu/ms for patients with pseudoexfoliation syndrome and 18.3 ± 1.8 pu/ms for those without ( P = 0.030). Best corrected visual acuity gain and best corrected visual acuity at 28 days were less in patients having pseudoexfoliation syndrome compared to those without (0.39 ± 0.07 vs 0.59 ± 0.03 decimals, P = 0.007; and 0.77 ± 0.06 vs 0.92 ± 0.03 decimals, P = 0.008, respectively).Conclusion:Eyes with pseudoexfoliation syndrome may be predisposed to an increased aqueous flare and macular edema after cataract surgery. This study outlines the need to determine the optimal anti-inflammatory medication after cataract surgery in patients with pseudoexfoliation syndrome.
