Purpose. The treatment of idiopathic macular holes has been basically modeled, and vitreoretinal surgery is recognized as an effective treatment. However, the postoperative tamponade of gas will still make the patient uncomfortable and may have related complications. The purpose of this study is to investigate whether air as an intraocular tamponade is equivalent to gas and what advantages may exist. Methods. A retrospective study was performed in one hundred and ninety-eight patients from 2013 to 2017; 112 received gas tamponade and 86 received air tamponade. After receiving retinal surgery, the outcomes of best corrected visual acuity, intraocular pressure, slit lamp examination, fundus examination, and imaging of the macula by spectral-domain optical coherence tomography were analyzed. Results. Before operation, there was no statistically significant difference in age, sex, macular hole diameter, or visual acuity between groups. The median follow-up period for the C3F8 group was 26 months, and the median follow-up for the air group was 25 months. After the operation, the best corrected visual acuity and macular hole closure rate were not significantly different between the two groups. The face-down time after the operation, the incidence of lens opacity on the third postoperative day, the intraocular pressure on the third postoperative day, and the operation time were significantly different between the two groups. Conclusions. In idiopathic macular hole surgery, the effect of air as an intraocular tamponade material can be similar to that of C3F8 but has fewer complications. In particular, it is a better choice for patients for whom the face-down position is not suitable.

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.

Peripapillary Staphyloma

A healthy 4-year-old male presented a fundus examination with a unilateral contractile peripapillary staphyloma surrounded by redundant retina and retinal pigment epithelium atrophy. Five years later, best-corrected visual acuity decreased to hand motion due to a retinal detachment with macular hole. One month after first vitrectomy, scleral buckle and intraocular gas, retina re-detached. Second surgery was performed with silicon oil tamponade and lensectomy without intraocular lens (IOL). Subretinal silicon oil was detected at the third month of follow-up when vitrectomy, inferior retinectomy, and laser photocoagulation of temporal border of staphyloma with silicon oil tamponade were performed. The retina remained attached and best-corrected visual acuity was 20/600 with intraocular silicon oil. A fourth surgery was performed for emulsified silicon oil extraction replaced with intraocular gas. At 6 months of follow-up, the retina re-detached again. This is a challenging vitreoretinal surgery in which re-detachments were due to retinal folds around the contractile staphyloma that raised macular hole. This is the first report of the combined presentation of contractile peripapillary staphyloma, retinal detachment and macular hole with a long-time follow-up period of years.

To study the efficacy of pneumatic induction of posterior vitreous detachment for the treatment of vitreomacular traction syndrome, the analysis of the results of surgical treatment of 10 patients (10 eyes) with vitreomacular traction syndrome was performed, among them 8 patients (8 eyes) had an accompanied immature age-related cataract and 2 patients (2 eyes) - pseudophakia. The average age of the patients was 64.1±4.6 years, among them 8 women and 2 men. The mean best corrected visual acuity on admission was 0.31±0.15, the average length of vitreomacular adhesion and retina thickness in the fovea by optical coherence tomography were 289.3±75.4 and 367.5±50.3 μm, respectively. Patients with pseudophakia underwent pneumatic induction of the posterior vitreous detachment, and patients with cataract underwent the same surgery in combination with phacoemulsification of the cataract and intraocular lens implantation. Within 1 month of follow-up, all patients had a complete posterior vitreous detachment and increased best corrected visual acuity. Intraocular pressure remained normal throughout the follow-up period in 9 out of 10 patients, 1 patient experienced hypertension on day 1 after the surgery, which required decompression during the gas expansion period. Further on, intraocular pressure was normalized and did not require therapy. Pneumatic induction of posterior vitreous detachment is an effective method of treatment of vitreomacular traction syndrome, which allows eliminating vitreomacular traction; the combination of pneumatic induction of the posterior vitreous detachment with phacoemulsification of cataract allows avoiding hypertension during and after operation and avoiding performing vitrectomy.

AimTo determine the outcomes of Aurolab aqueous drainage implant (AADI) placed in the superotemporal versus the inferonasal quadrant in adult eyes with refractory glaucoma.MethodsThis was a retrospective study of eyes that had AADI placement and completed a minimum of 2-year follow-up. The choice of the quadrant was at the surgeon’s discretion and mainly depended on the amount of scarring and conjunctival mobility. The cumulative failure rate of the AADI was defined as intraocular pressure (IOP) >21 mm Hg or not reduced by 20% below baseline on two consecutive follow-up visits after 3 months, IOP ≤5 mm Hg on two consecutive follow-up visits after 3 months, reoperation for glaucoma or a complication, or loss of light perception vision.ResultsWe included 84 eyes with AADI in the inferonasal quadrant versus 69 eyes in the superotemporal quadrant. A significant drop in IOP was seen in both groups (18.4±10.4 mm Hg in the inferonasal group vs 17.7±11.1 mm Hg in the superotemporal group; p=0.63) at 3-month follow-up and this was maintained until last follow-up. Best-corrected visual acuity, IOP, number of IOP-lowering medications and complications were similar between the two groups at all time points. The cumulative success rate at 2-year follow-up without IOP-lowering medications was 57.1% (47.1%–68.1%) in the inferonasal group and 50.7% (39.8%–63.1%) in the superotemporal group (p=0.47).ConclusionsInferonasal AADI placement appears to be an equally safe and effective surgical option compared with superotemporal AADI placement and may be helpful in certain clinical situations.

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

Abstract Background：Vitrectomy and membrane peeling followed by gas filling technique has become a standard procedure of macular hole surgery, the outcomes are affected by many factors, and which kind of intraocular tamponade is the best choice still has some conflicts. The purpose of this study is to investigate whether air filling can achieve comparable effects to long-acting inert gases when different macular hole sizes are enrolled. Methods：116 patients with idiopathic macular hole were enrolled in this retrospective study, 44 received C3F8 tamponade and 72 received sterile air tamponade. Before and after vitrectomy surgery, the best corrected visual acuity, slit lamp examination, fundus examination and intraocular pressure were analyzed. Results：No statistically significant difference was fund in age, gender, axial length, intraocular pressure, or preoperative visual acuity between groups. After the surgery, the closure rates of air group and C3F8 group with macular hole diameter ≤400 microns were 94.4% and 100.0%, with no significant difference between the two groups (P = 0.701). The closure rates of macular hole diameters lager than 400 microns are 66.7% and 91.3%, P = 0.029. The total closure rates of the two groups are 80% and 95.6%, P =0.018. Conclusions：In idiopathic macular hole surgery, the effect of air as an intraocular tamponade material is similar to that of C3F8 in macular hole with diameters less than 400 microns. In patients with larger macular hole (diameter over 400 microns) performed therapeutic surgery with air filling, internal limiting membrane insertion or flap inversion may be recommended get better outcomes.

AIM: To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis. METHODS: Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy (PPV) combined with scleral shortening were reviewed. Axial length (AL), the height of macular retinoschisis, the height of retinal detachment if existed, the diameter of macular hole if existed and best corrected visual acuity (BCVA) were obtained. The preoperative and postoperative parameters were compared. RESULTS: At postoperative 24mo, the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51 μm (t=8.064, P<0.0001; Z=-5.086, P<0.0001) respectively. In addition, the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38 μm and 183.68 μm (Z=-4.457, P=0.000008; Z=-2.983, P=0.003) respectively. Meanwhile, the postoperative BCVA was improved markedly (Z=-2.126, P=0.033). CONCLUSION: Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis, whether or not macular hole and retinal detachment are present.

Background/aimsTo investigate the surgical outcomes of posterior scleral reinforcement (PSR) using genipin-cross-linked sclera to treat macular hole retinal detachment (MHRD) in highly myopic eyes.MethodsNineteen patients with high myopia (19 eyes) with MHRD were treated sequentially with genipin-cross-linked PSR and were followed at least for 1 year after the surgery. The best corrected visual acuity (BCVA), axial length (AL), optical coherence tomography (OCT) outcomes and the complications were evaluated.ResultsMacular hole was closed in 73.7% of the eyes, foveal reattachment rate was 100%. The mean logMAR BCVA improved from 1.27±0.55 preoperatively to 0.88±0.55 postoperatively. The preoperative AL (29.88±1.97 mm) was decreased (27.73±1.84 mm) after the operation (p<0.001).ConclusionsFor at least a 1-year period of follow-up, PSR with genipin-cross-linked sclera should be considered as a preferred surgical approach to treat MHRD in highly myopic eyes, especially when foveal retinoschisis is also documented.

Abstract Purpose: To evaluate the efficacy of trabeculectomy with intraoperative subtenon injection of Mitomycin C (MMC) in terms of control of Intraocular pressure post-operatively.Study design: Observational studyMethods: A total of 49 patient’s medical records who underwent trabeculectomy with intraoperative subtenon injection of MMC with diagnosis of Primary Open Angle Glaucoma (POAG) from January 2017 to December 2018 were evaluated to see the post-operative outcomes in terms of control of intraocular pressure (IOP) with 12 months follow-up. The medical records were retrieved using the hospital information system. Age, gender, pre-operative IOP, Best-Corrected Visual Acuity (BCVA), co-morbids, previous surgery, Central Corneal Thickness (CCT), fundus findings, number of glaucoma medications and postoperative complications were obtained by using a proforma.Results: Total 72 eyes of 49 patient records were evaluated to see post operative outcomes at three, six and twelve months follow up. The mean IOP preoperatively was 24.68±13.66 mm Hg with maximum anti-glaucoma treatment. After the surgery the mean IOP was 13.69±6.68 mmHg at 3 months follow-up, and 12.68±4.04 and 13.33±4.8 mmHg at 6 and 12 months respectively (P-value 0.001). Preoperatively mean CCT was 529.81±28.75 and at 12 months follow-up after surgery was 530.45±29.43 with P-value 0.245. Best Corrected Visual Acuity outcomes were seen at each follow-up and results were found to be statistically significant (P value ≤ 0.05).Conclusions: Twelve months follow-up of trabeculectomy show that intraoperative subtenon injection of MMC is effective in terms of control of IOP postoperatively with minimal complications in patients with POAG.

Cyclodestructive procedures are an alternative of surgical treatment of medically refractory glaucoma. Aim: To assess efficiency and safety of diode cyclophotocoagulation (CPC). Methods: Retrospective study included 81 eyes with advanced glaucoma operated with CPC for elevated intraocular pressure (IOP) from January 2017 to January 2019. CPC was performed in retrobulbar anesthesia with contact diode laser FOX (A.R.C. Laser, Germany) of wavelength 810 nm, transsclerally to the ciliary body. Energy settings: intensity 2 W, exposition time 2 s, 18 applications in arc of 360°. Decrease of intraocular pressure was investigated during month 1, 6 and 12 after CPC. Safety was evaluated according to the best corrected visual acuity (BCVA) on Snellen optotypes and number of postoperative complications. Results: Study on 31 eyes of 24 patients, 21 (68 %) women and 10 (32 %) men, with follow-up during more than 12 months. Mean follow-up time was 19.5 ± 6.1 (from 12 to 29) months. Average age was 75.9 ± 9.2 (56 - 93) years. Indication for CPC was primary open angle glaucoma in 15 eyes (49 %), primary angle closure glaucoma in 6 eyes (19 %) and secondary glaucomas in 10 eyes (32 %). All patients were on therapy of 4 antiglaucomatic drops and 10 of them (32 %) on acetazolamide pills. IOP before CPC was 25.4 ± 11.0 (13–56) mm Hg. After 1 year IOP decreased to 16.9 ± 6.1 (8–40) mm Hg. Best corrected visual acuity (BCVA) before CPC was 0.39 ± 0.34 (0-1), 1 year after CPC 0.36 ± 0.33 (0-1). 1 year after CPC, 11 eyes (35 %) lost 0.23 ± 0.14 rows. 6 from these (19 %) due to other acquired ocular pathologies. Hypotony occurred in 6 % and uveitis in 10 % eyes. Conclusion: CPC is a safe and effective method of lowering IOP.
