Purpose: To report a case of endophthalmitis and retinal detachment after injury caused by an animal inoculation needle. Case summary: A 39-year-old man received an injury to his left eye with an animal inoculation needle while vaccinating a pig came to the hospital due to decreased visual acuity. At initial presentation, the best-corrected visual acuity in the left eye was “counting fingers,” and slit lamp examination revealed corneal lacerations, anterior capsule rupture, and traumatic cataract. Ultrasonography showed no specific findings in the vitreous and retina. Primary corneal suture, phacoemulsification, anterior vitrectomy due to rupture of the posterior capsule and vitreous prolapse, intraocular lens implantation, and intravitreal antibiotic injection were performed. On day 1 postoperatively, vitrectomy, anterior chamber irrigation, intravitreal antibiotic injection, and silicone oil injection were performed as signs of endophthalmitis, such as hypopyon and retinal tear, and focal retinal detachment were observed during surgery. Silicone oil removal was performed 7 months after the operation and the best-corrected visual acuity was 0.6. There has been no recurrence during follow-up. Conclusions: This is the first report in Korea of ocular injury caused by an animal inoculation needle. If the fundus is not observed in such injuries, there is a possibility of endophthalmitis and retinal detachment and early vitrectomy should be considered.

Abstract Purpose To investigate the macular vessel density and thickness in macular-on rhegmatogenous retinal detachment (RRD) after vitrectomy with gas and silicone oil (SO) tamponade. Methods Patients with macular-on RRD eyes, treated with a single successful vitrectomy with gas or SO tamponade and a minimum 30 months follow-up, were reviewed. Best-corrected visual acuity (BCVA), macular vessel density and retinal thickness by using optical coherence tomography angiography, were compared to the contralateral eyes. Results Sixteen eyes with gas tamponade and 17 eyes with SO tamponade were included in the study. LogMAR best-corrected visual acuity (BCVA) slightly improved from 0.25 ± 0.18 (Snellen 20/36) to 0.17 ± 0.23 (Snellen 20/30) in eyes with gas tamponade, and decreased from 0.30 ± 0.22 (Snellen 20/40) to 0.49 ± 0.28 (Snellen 20/62) in eyes with SO tamponade. The parafoveal vessel densities in superficial vascular complex (SVC) and the corresponding inner retinal thickness (IRT) were similar between the affected eyes and the contralateral eyes in gas tamponade group (P = 0.578, P = 0.943), while significantly reduced in the affected eyes, compared to the contralateral eyes in SO tamponade group (P < 0.001, P < 0.001). Conclusion Eyes in SO tamponade group had worse BCVA, lower SVC vessel densities and thinner corresponding IRT after vitrectomy for macular-on RRD, than those in gas tamponade group.

Purpose: To compare the efficacy of ranibizumab and aflibercept in the treatment of diabetic macular edema associated with subfoveal retinal detachment. Methods: This is a retrospective, comparative study. The treatment-naïve diabetic macular edema patients who had diabetic macular edema associated with subfoveal retinal detachment and underwent intravitreal aflibercept or intravitreal ranibizumab treatment were included. The patients were treated on a pro re nata treatment regimen after a loading dose of 3-monthly injections and the follow-up time was 12 months. The primary outcome measure of this study was the presence of subfoveal retinal detachment after treatment at different time points. The secondary outcome measures were the change in best corrected visual acuity and central retinal thickness. Results: A total of 46 eyes of 46 patients were included. The aflibercept group consisted of 20 and the ranibizumab group consisted of 26 eyes. During the follow-up period of 12 months, subfoveal retinal detachment was completely resolved in 75% versus 57.7% of the eyes at month 3 (p = 0.2), 90% versus 76.9% at month 6 (p = 0.2), 90% versus 65.4% at month 9 (p = 0.05), and 100% versus 80.8% at month 12 (p = 0.03) in the intravitreal aflibercept versus intravitreal ranibizumab groups. The change in best corrected visual acuity was not statistically different between the groups at months 3, 6, 9, and 12, respectively (p > 0.05 for all). Conclusion: Both intravitreal aflibercept and intravitreal ranibizumab were effective in regards to anatomical and functional outcomes of diabetic macular edema patients associated with subfoveal retinal detachment. Interestingly, intravitreal aflibercept seemed more effective than intravitreal ranibizumab in the resolution of subfoveal retinal detachment at month 12.

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.

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.

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.

Background Removal of an embedded intraocular foreign body remains challenging due to the risks of bleeding and retinal damage. We present a novel technique to deal with this situation. Case report A 32-year man presented with two months of decreased vision in one eye (best corrected visual acuity of 20/200), a year after a workplace injury that necessitated surgery for an open globe injury. Examination revealed the sequalae of his previous surgery, a subtotal retinal detachment and an embedded intraocular foreign body close to inferior ora serrata at the 6 'o clock position confirmed by imaging. The other eye was normal. A pars plana vitrectomy was performed and the embedded intraocular foreign body was released from surrounding dense adhesions using the vitrectomy probe set at 1000 cuts/minute and 100 mm Hg vacuum, followed by fluid air exchange and endolaser with silicon oil injection. The retinal detachment settled well post-operatively, and at the end of one month, the patient had best corrected visual acuity of 20/60. Conclusions The low-cut, low-vacuum vitrectomy technique can be considered as a safe option for releasing the embedded intraocular foreign body in complex ocular trauma scenarios.

Subretinal Strand

Recurrence of inferior retinal detachment, after vitreoretinal surgery and silicone oil tamponade, along with a subretinal strand, presents a challenge for surgeons. Vitrectomy and retinotomy are the usual treatment in such cases. Here, we present a new transscleral method for addressing this problem. A 13-year-old boy with recurrent retinal detachment after silicone oil tamponade underwent scleral buckling surgery and had a transscleral subretinal strand removed without retinotomy. The retina reattached, and silicone oil was removed 3 months later. The best-corrected visual acuity was 0.4 in decimal vision at 1 year after silicone oil removal. Scleral buckling surgery combined with subretinal strand removal may be used as an alternative to retinotomy, especially for patients with an inferior retinal detachment and local subretinal strand formation.

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.
