PURPOSE: To report a rare case of relapsed inflammatory choroidal neovascularization (CNV) in a young female patient after intravitreal bevacizumab (IVB) treatment for subfoveal CNV secondary to punctate inner choroidopathy (PIC). CASE SUMMARY: A 25-year-old myopic female presented with PIC complicated by subfoveal CNV in the right eye. Her lesion initially responded to three monthly 1.25 mg IVB injections, but the lesion recurred two months after the final injection, and the size of the lesion was larger than that observed before treatment. Further treatment with systemic steroids and IVB resulted in successful anatomic and visual improvement. CONCLUSIONS: This report presents a rare case of relapsed inflammatory CNV in a young female patient after IVB treatment for subfoveal CNV secondary to PIC. Systemic steroid and IVB were performed after relapse, which successfully improved and maintained vision for longer than 18 months.

PURPOSE: To report the manifestation of ocular syphilis combined with neurosyphilis in patients who present with uveitis clinically and are diagnosed initially by an ophthalmologist. METHODS: This study is a retrospective, clinical investigation of seven male patients with ocular syphilis from a single tertiary center between 2009 and 2012. RESULTS: The average age of the patients at onset was 44.4 years (range, 33-71 years). Posterior segment involvement was found in all patients. Two patients had papillitis. In serologic testing, all patients had positive responses to Venereal Disease Research Laboratory (VDRL), fluorescent treponemal antibody-absorption test (FTA-ABS) and Treponema pallidum hemagglutination (TPHA). In fluorescein angiography (FAG), retinal vascular and disc leakage was the most common finding. Cerebrospinal fluid (CSF) analysis was performed for six patients and demonstrated positive CSF FTA-ABS and CSF TPHA tests in all patients. CSF VDRL was reactive in 2 patients (33.3%). CONCLUSIONS: All patients with ocular syphilis were diagnosed with neurosyphilis based on the analysis of CSF with FTA-ABS and TPHA. Ophthalmologists play an important role in the early diagnosis and treatment of syphilis.

PURPOSE: To compare the two transscleral fixation (TSF) techniques of intrascleral pocket and conventional scleral flap with conjunctival division techniques in terms of short-term clinical effects. METHODS: This retrospective cohort study included all consecutive patients with aphakia in Gyeongsang National University Hospital in Jinju, Korea, who underwent TSF between January 2012 and December 2014. The medical records of all patients were retrospectively reviewed, and the endothelial cell count (ECC), refraction, best-corrected visual acuity (BCVA), intraocular pressure, slit lamp, and fundus examination results before and 1 day and 6 months after surgery were recorded. The postoperative complications and visual outcomes were also recorded. RESULTS: The intrascleral pocket and conventional-flap groups did not differ significantly in terms of demographics, presurgical BCVA, or ECC. However, the intrascleral pocket group had a significantly lower BCVA at 1 day and 6 months after surgery compared to the conventional-flap group. The two groups did not differ in terms of ECC 6 months after surgery. The intrascleral pocket group had no postoperative complications, but five patients in the conventional-flap group complained of irritation. In both groups, the intraocular lens was well positioned without tilting or subluxation, and astigmatism was significantly reduced at 1 day and 6 months after surgery. CONCLUSIONS: The intrascleral pocket technique of TSF does not involve conjunctival dissection and is a successful method of sulcus fixation. It stably corrects the intraocular lens and is easy to perform, which helps to reduce operation time. It also reliably yields rapid visual acuity recovery without complications.

In this case series, we assessed a new technique, the intrascleral pocket procedure of transscleral fixation (TF) of the intraocular lens (IOL) in post-vitrectomized eyes. We performed the transscleral fixation of IOL in four aphakic patients who underwent pars plana vitrectomy. Two points 180degrees apart were marked at the limbus. A 2-mm-sized intrascleral pocket was created by lamellar dissection using a crescent blade without conjunctival dissection. A 2.8-mm clear corneal incision (CCI) was made using a keratome. Prolene sutures were exteriorized through the CCI pocket and a three-piece foldable acrylic IOL was injected via CCI and the ends of the haptics were exteriorized through the CCI. The prolene sutures for each haptic in the intrascleral pocket bed were then tied and knots were buried under scleral flaps. No patient had complaints such as conjunctival irritation, and visual acuity was almost identical to preoperative best-corrected visual acuity at day 1 postoperatively. IOLs were well placed without tilting or subluxation. They had no wound dehiscence or endophthalmitis postoperatively. The intrascleral pocket procedure of TF without the need for conjunctival dissection is a successful method for sulcus fixation in post-vitrectomized eyes predisposed to developing glaucoma.

PURPOSE: To compare the choroidal thickness of unaffected and affected eyes in children with unilateral high myopia when measured using enhanced depth imaging and to analyze the relationship among choroidal thickness and axial length, spherical equivalent and best corrected visual acuity (BCVA). METHODS: Twenty children with high unilateral high myopia who received optical coherence tomography from December 2012 to May 2014 were retrospectively analyzed. Choroidal thickness was measured with a caliper at 500 microm apart from fovea superiorly and inferiorly, 2,500 microm apart nasally and at 2,500 microm apart temporally at 500 microm intervals. For statistical analyses, paired t-test was used for choroidal thickness and linear regression analysis for the relationship among choroidal thickness and axial length, spherical equivalent and BCVA. RESULTS: The patients were 10.4 +/- 3.5 years of age and the average BCVA of myopic eye was 0.38 +/- 0.2. Mean spherical equivalent was -9.8 +/- 1.9D. The choroidal thickness was significantly thinner in the myopic eye (102.5 +/- 16.9 microm) than the fellow eye (282.9 +/- 14.0 microm). The thickest choroid in the myopic eye was the temporal and the thinnest was the nasal area (p = 0.008). Choroidal thickness was significantly associated with axial length and spherical equivalent but not BCVA. CONCLUSIONS: Highly myopic eyes tend to have thinner choroidal thickness than the fellow eyes and choroidal thickness tends to be thicker temporally. Therefore, several anatomical changes in unilateral highly myopic children may exist.

PURPOSE: To report a case of Epstein-Barr virus-related corneal endotheliitis accompanied by secondary glaucoma.CASE SUMMARY: A 73-year-old male presented with blurred vision in his right eye. In the ophthalmic evaluation, there were dispersed keratic precipitates overlying corneal edema. The anterior chamber showed trace ~1+ graded inflammation and an endothelial density decrease. His best-corrected visual acuity and intraocular pressure in the right eye were 0.2 and 34 mmHg, respectively. Paracentesis was performed on the anterior chamber of the right eye to confirm the diagnosis under the suspicion of corneal endotheliitis with trabeculectomy for the intraocular pressure control. Epstein-Barr virus was confirmed using a multiplex polymerase chain reaction (PCR), and oral and eye drops of Acyclovir were used to treat the patient. There was no evidence of a recurrence over 2 years and his intraocular pressure was 12 mmHg and best-corrected visual acuity was maintained at 0.5.CONCLUSIONS: A case of Epstein-Barr virus-related corneal endotheliitis was diagnosed using PCR of the aqueous humor. The patient was treated with an oral antiviral agent and eyedrops without a recurrence.

Purpose:
Here, we report a case of a fungal corneal ulcer caused by Talaromyces allahabadensis (T. allahabadensis).Case summary: A 69-year-old male was admitted to our hospital with pain and hyperemia in his left eye after 2 months of treatmentat a local clinic for herpetic keratitis. The patient had a previous history of trauma to his left eye caused by a persimmon treebranch. He had a peripheral epithelial defect, stromal infiltration, and severe corneal edema in his left eye. Gram staining, a KOHsmear, and a culture were performed using corneal specimens; the results were all negative. With the assumption of herpetickeratitis, antiviral and empirical antibiotic treatments were started. After 2 weeks, the stromal infiltrations on his left eye increased,so we again conducted staining and culture studies. T. allahabadensis was isolated from a specimen, so treatment wasstarted using antifungal agents, and a conjunctival flap graft was performed due to the risk of a corneal perforation.
Conclusions
A case of corneal ulcer caused by T. allahabadensis in a patient with posttraumatic herpetic keratitis was successfullytreated with antifungal agents and conjunctival flap surgery.

Purpose:
To report a case of bilateral congenital cataract in a patient with triple X syndrome.Case summary: A 9-month-old female was referred to our clinic because of poor fixation and white pupils in both eyes. The patient underwent a performed chromosomal study in the pediatric department due to developmental delay and torticollis. As a result, she was diagnosed with triple X syndrome (47, XXX). Under general anesthesia, the patient underwent lens aspiration with intraocular lens insertion and anterior vitrectomy was performed followed by posterior capsulotomy with optic capture. Intraoperatively, remnant pupillary membrane, posterior embryotoxon, and anterior lenticonus with anterior capsular defect in both eyes were observed. But there was no specific finding on fundus examination.
Conclusions
We report the first case of bilateral congenital cataract in a patient with triple X syndrome. It is recommended that clinicians check for cataracts as soon as possible when this chromosome abnormality is confirmed.

Purpose:
To report a case of acute angle-closure attack resulting from hemorrhagic retinal detachment after a double retinal pigment epithelium (RPE) tear in exudative age-related macular degeneration (AMD) with large pigment epithelial detachment (PED).Case summary: A 66-year-old female visited with a complaint of poor vision in left eye, which began 1 month prior. She was diagnosed with exudative AMD with a large PED using optical coherence tomography and indocyanine green angiography. Intravitreal aflibercept injection was performed. The RPE tear occurred at 2 weeks after the intravitreal anti-vascular endothelial growth factor injection for AMD, after which the range of the RPE tear expanded and included the macular area at 4 weeks after the second injection. At 3 months after the third injection, massive submacular hemorrhage occurred; aflibercept injection was repeated. At 3 days after the fourth injection, the patient’s intraocular pressure (IOP) was 60 mmHg, and massive hemorrhagic serous retinal detachment and anterior movement of the lens with total angle closure were observed. Therefore, we performed a sclerotomy; a large amount of dark blood and subretinal fluid was drained. The IOP decreased, and the retinal detachment improved somewhat. The patient was kept under observation for careful monitoring of her condition.
Conclusions
It is very rare to experience a double RPE rupture after intravitreal anti-vascular endothelial growth factor injection in AMD. We report on our experience and treatment of acute angle-closure attack. The IOP increased due to hemorrhagic retinal detachment after a double RPE tear over the treatment course.

Purpose:
This study investigated the 1-year outcomes of a treat-and-extend regimen of ranibizumab for exudative age-related macular degeneration and examined the clinical results when drug treatment was changed within the same period.
Methods:
This retrospective analysis included 32 eyes first diagnosed with wet age-related macular degeneration and treated for more than 1 year with a treat-and-extend regimen of ranibizumab, as well as 24 eyes treated by changing from ranibizumab to aflibercept within the same period. The injection number, maximum injection interval, change in central retinal thickness, and best-corrected visual acuity were assessed in all eyes.
Results:
In 32 eyes that received a treat-and-extend regimen of ranibizumab, the mean best-corrected visual acuity improved from 59.46 ± 15.13 to 68.00 ± 12.48 at 12 months (p < 0.0001). The mean central retinal thickness decreased from 409 ± 141 μm to 273 ± 89 μm at 12 months (p < 0.0001). The average number of injections per year was 7.2 ± 0.85. One complication related to the 12 months of injections was a tear in the retinal pigment epithelium; no systemic complications were observed. Of 24 eyes that underwent a change in medication, the rate of maintenance or improvement in initial visual acuity was 83% (10 eyes). The central retinal thickness was initially 371.58 ± 109.96 μm, but improved to 290.33 ± 58.66 μm in 12 eyes that received three injections of aflibercept.
Conclusions
At 1 year, good outcomes were obtained using treat-and-extend ranibizumab for exudative age-related macular degeneration. When the treatment was changed to aflibercept within the same period, vision was often maintained and short-term anatomical improvement was evident.
