RESUMEN

PURPOSE@#We present four cases of welding arc maculopathy as observed using spectral-domain optical coherence tomography (SD-OCT).CASE SUMMARY: Four patients, who performed welding without wearing protective eye gear, presented to the hospital due to poor visual acuity. The mean visual acuity of the patients was 0.6. Fundus photographs of the four patients revealed a yellowish retinal scar at the fovea. SD-OCT images of the four patients showed photoreceptor inner segment/outer segment junction (IS/OS junction) disruption and retinal pigment epithelium injury. We diagnosed the patients with welding arc maculopathy, and three of them were treated with oral steroids or antioxidants. The IS/OS junctions were restored in two patients, who had short welding arc exposures. The disrupted IS/OS junction recovered partially in one of the other two patients, who had a longer duration of exposure, and the IS/OS junction disruption remained in another patient.@*CONCLUSIONS@#We report four cases of welding arc maculopathy caused by welding light exposure evaluated using SD-OCT and treated with oral steroids and antioxidants.

RESUMEN

PURPOSE: We report a case of acute visual loss with ophthalmoplegia after prone position spinal surgery who had blood supply dependence on collateral circulation due to occlusion of the Internal carotid artery. CASE SUMMARY: A 74-year-old man was referred to the department of ophthalmology for acute visual loss and ophthalmoplegia after lumbar spine surgery performed in prone position. On the initial visit, his right visual acuity was 0.8 and the left visual acuity was negative light perception. Intraocular pressure was normal. There was a relative afferent pupillary defect and ophthalmoplegia of all directions in the left eye. Because of the ptosis of the upper eyelid in the left eye, it was impossible to tune the eye voluntarily. The cherry red spot and pale retina were observed on the fundus examination. On brain magnetic resonance imaging angiography, we found complete obstruction of the left internal carotid artery. He had intravenous injection of 1 g methylprednisolone for 3 days, and discharged with per oral medicine. After 1 month of treatment, the ophthalmoplegia was slightly improved, but visual acuity was not recovered. CONCLUSIONS: In this case, unlike previous reports, acute visual loss and ophthalmoplegia occurred after spinal surgery the patient who had collateral circulation for ocular blood supply because of complete obstruction of the left internal carotid artery. This report highlights the importance of being aware of the anatomical variant in possible complications of external ocular compression after non-ocular surgery.

RESUMEN

PURPOSE: To describe the clinical manifestations of herpes simplex keratitis (HSK) in a tertiary referral center in South Korea and to determine whether ascorbic acid treatment prevents recurrence of herpetic epithelial keratitis. METHODS: This retrospective cohort study included all consecutive patients with herpetic keratitis referred to our center from January 2010 to January 2015. Clinical features, ocular complications, and recurrences were recorded. RESULTS: In total, 149 eyes of the 133 patients (72 male and 61 female) were followed for an average of 24.6 ± 13.2 months. Sixteen (12.0%) patients had bilateral HSK. The most frequent HSK subtype was epithelial keratitis (49.7%), which was followed by stromal keratitis (23.5%). Epithelial keratitis was the most likely subtype to recur. Complications occurred in 122 (81.9%) eyes. The most common complication was corneal opacity. Recurrences were observed in 48 (32.2%) eyes. The recurrence rates were lower in the prophylactic oral antiviral agent group (16 / 48 eyes, 33.3% vs. 49 / 101 eyes, 48.5%) and the ascorbic acid treatment group (13 / 48 eyes, 27.1% vs. 81 / 101 eyes, 70.3%) compared with the groups without medications. Univariate logistic regression analysis revealed that both factors significantly reduced the risk of recurrence (acyclovir: odds ratio, 0.25; 95% confidence intervals, 0.12 to 0.51; ascorbic acid: odds ratio, 0.51; 95% confidence intervals, 0.20 to 0.91). CONCLUSIONS: This retrospective study described the clinical findings of HSK in a tertiary referral center in South Korea. Prophylactic oral antiviral agent treatment and oral ascorbic acid administration may lower the risk of recurrence.

RESUMEN

PURPOSE: To report a case of anterior segment ischemia after superior and inferior rectus muscle surgery in a patient with superior rectus muscle enlargement. This is the first report in the Republic of Korea of anterior segment ischemia after two rectus muscles surgery. CASE SUMMARY: An 80-year-old male was referred to our clinic with a 3 years history of diplopia. The patient had 30 prism diopters right eye hypertropia in the primary position and downgaze limitation. The orbital computed tomography scan revealed enlargement of the right superior rectus muscle. He underwent right superior rectus recession and inferior rectus resection. On postoperative day 2, slit lamp examination revealed diffuse corneal edema, Descemet's membrane folding, an aqueous flare and a dilated pupil. Treatment with 45 mg oral steroid was initiated, and 1% prednisolone acetate and 0.5% Levofloxacin eye drops were administered. At postoperative 1 month, the patient was orthophoric in the primary position, and there was no corneal edema, pupil abnormality or aqueous flare. CONCLUSIONS: Base on the present case, the possibility of anterior segment ischemia should be considered after even two muscles surgery, and older patients with vertical muscle surgery should be considered more carefully.

RESUMEN

PURPOSE: To investigate the change of refractive error between the full-correction and under-correction treatment groups of myopic anisometropic patients. METHODS: This study included 36 patients who had no amblyopia with myopic anisometropia > 3.00 diopters (D) and less than 6.00 D using the cycloplegic refraction test. The patients were divided into two groups involving the full-correction of both eyes (group 1) or full-correction on the less myopic eye and under-correction with −0.50 D of the more myopic eye (group 2). We monitored refractive changes every 6 months for 24 months. RESULTS: At the first visit, the mean refractive error of the less myopic eye was −0.68 ± 0.54 D and that of the more myopic eye was −4.22 ± 0.77 D in group 1. The mean refractive error of the less myopic eye was −0.75 ± 0.58 D and that of the more myopic eye was −4.36 ± 0.73 D in group 2. There was no significant difference between the groups (p = 0.713 and p = 0.585, respectively). At 24 months, the mean refractive errors of group 1 were −1.27 ± 0.54 D and −4.88 ± 0.81 D, respectively, and that of group 2 were 1.38 ± 0.54 D and −5.59 ± 1.01 D, respectively. The mean refractive error of the less myopic eyes showed no significant difference between both groups (p = 0.555), but that of the more myopic eyes was significantly different (p = 0.027). Between both groups, the degree of anisometropia at 24 months was 3.61 ± 0.60 in group 1 and 4.20 ± 0.86 in group 2. Group 2 showed a significant difference and more severe anisometropic changes (p = 0.022). CONCLUSIONS: Full correction of myopic anisometropia without amblyopia is a better method for reducing the progression of anisometropia.

RESUMEN

PURPOSE: We report our experience with a case of orbital lymph node which has not been previously reported in the Republic of Korea. CASE SUMMARY: A 24-year-old female patient with no underlying disease visited our hospital with a 2-month history of a mass at the lateral side of the left upper eyelid. On physical examination, a round, well-defined subcutaneous mass was palpable, and pain, swelling or a skin change were not reported or seen. The appearance, location, and imaging findings of the mass were suspected to be dermoid, and excisional biopsy was performed for accurate diagnosis and treatment. The 1.0 × 0.7 cm-sized, round-shaped and brown-colored mass was excised. The mass was well-defined but in the posterior part; it was attached to the periosteum. The mass was finally diagnosed as a lymph node with lymphadenitis by histopathological examination. No recurrence or new lesion was observed after surgery, and the patient did not complain of abnormal symptoms. CONCLUSIONS: A Complete orbital lymphoid tissue has not yet been found in the orbit, and lymph nodes are known to be absent. However, as in this case, when an orbital mass is observed, the possibility of lymph node should be considered and histopathological examination should be performed to confirm it.

RESUMEN

PURPOSE: To report the first case of cystoid macular edema in a retinitis pigmentosa patient with pars plana vitrectomy. CASE SUMMARY: A 43-year-old female visited our hospital with visual disturbances of both eyes. Corrected visual acuity was 20/22 in the right eye and 20/25 in the left eye. Peripheral depigmentation and atrophy of the retinal pigment epithelium, pigmentary retinal degeneration, and attenuated arterioles were observed in both eyes. Cystoid macular edema was observed on optical coherence tomography which showed that the central macular thickness was 308 µm in the right eye and 422 µm in left eye. Intravitreal aflibercept was injected into the left eye. One month after injection, the central macular thickness showed no response with a thickness of 449 µm. An intravitreal dexamethasone implant was then injected, 1 month after injection, the central macular thickness was 367 µm. Six months after injection, the patient again complained of visual disturbance of the left eye with a corrected visual acuity of 20/70. Vitreous opacity was observed and the central macular thickness was 501 µm. The patient underwent pars plana vitrectomy. Three days after surgery, the central macular thickness was 320 µm. One year after surgery, the corrected visual acuity was 20/33 and the central macular thickness was 311 µm. CONCLUSIONS: Pars plana vitrectomy due to cystoid macular edema in a retinitis pigmentosa patient has not been previously reported in the Republic of Korea. Pars plana vitrectomy can therefore be an effective treatment for cystoid macular edema in retinitis pigmentosa patients.

RESUMEN

PURPOSE: To compare changes in anterior segment parameters after Nd:YAG laser capsulotomy in eyes that underwent either combined phacovitrectomy or cataract surgery. METHODS: This retrospective study enrolled 37 eyes of 35 patients with posterior capsular opacification treated with combined phacovitrectomy (group A), and 35 eyes of 32 patients with posterior capsular opacification treated with cataract surgery (group B). Anterior segment parameters, including anterior chamber depth (ACD), anterior chamber angle, and anterior chamber volume, were measured by a Pentacam before Nd:YAG laser capsulotomy and 1 hour, 1 day, 1 week, 1 month, and 3 months after this treatment. RESULTS: In the cataract surgery group, the ACD was significantly lower 1 day (3.75 ± 0.74 mm), 1 week (3.73 ± 0.24 mm), and 3 months (3.74 ± 0.33 mm) after Nd:YAG laser capsulotomy compared with the pretreatment value (4.20 ± 0.62 mm, p = 0.002). By contrast, the ACD did not change significantly over time in the combined phacovitrectomy group. The ACD differed significantly between the two groups at 1 week, 1 month, and 3 months after capsulotomy. There were no significant changes in the anterior chamber volume, anterior chamber angle, central corneal thickness, or pupil size from before to after capsulotomy in either group. A non-significant trend toward myopic shift was observed in group A (p = 0.072) and B (p = 0.055). CONCLUSIONS: The results of the present study may help determine the power of the intraocular lens in patients who underwent combined surgery or cataract surgery and who will receive Nd:YAG laser capsulotomy.

RESUMEN

PURPOSE: In this study, the changes in ocular surface parameters and tear meniscus after strabismus surgery when treated with or without artificial tears were evaluated using optical coherence tomography (OCT). METHODS: The present study included 30 patients who received bilateral lateral rectus recession surgery for exotropia. The patients instilled artificial tear eye drops only in the left eye. Before and 2, 4, 8, and 12 weeks after surgery, tear film break-up time (BUT), Schirmer's test, corneal staining test, tear meniscus height and area were measured using OCT and compared in both eyes. Before and 8 weeks after surgery, conjunctival compression cytology test was performed. RESULTS: The mean patient age was 8.7 years. After 8 weeks, BUT and corneal staining scores were 12.3 ± 1.5 seconds and 1.3 ± 0.4 in patients treated with artificial tears and 9.5 ± 1.0 seconds and 2.0 ± 0.7 in patients not treated with artificial tears (both p < 0.000). Four weeks after surgery, tear meniscus height and area using OCT were 290.2 ± 42.3 µm and 566.7 ± 48.2 pixels in patients treated with artificial tears and 246 ± 45.5 µm and 504.0 ± 29.7 pixels in patients not treated with artificial tears (p = 0.045 and p = 0.019, respectively). Goblet cell count was significantly different between the eyes 8 weeks after surgery (p = 0.033). CONCLUSIONS: Instability of tear meniscus can be detected after strabismus surgery using BUT, Schirmer's test, corneal staining test, tear meniscus height and area, and OCT. After surgery, artificial tears help treat dry eye symptoms by corneo-conjunctival wound healing mechanism and increasing tear meniscus stability.

RESUMEN

PURPOSE: To report a case of fragmentation and anterior migration occurred after dexamethasone intravitreal implant (Ozurdex®, Allergan, Irvine, CA, USA) injection in a branch retinal vein occlusion patient. CASE SUMMARY: A 66-year-old male was referred for blurred vision. He received cataract surgery in 1986 and was diagnosed with central retinal vein obstruction in 2011 in the right eye. For treatment of macular edema, dexamethasone intravitreal implant was performed in the right eye. One week after implantation, a fragment of the dexamethasone implant migrated to the anterior chamber with corneal edema and surgical removal was performed immediately. One day after removal, the remaining fragmented implant migrated to the anterior chamber and corneal edema still existed. The fragmented implant was removed with anterior chamber irrigation. After removal, corneal edema improved and visual acuity was recovered. CONCLUSIONS: Anterior migrated dexamethasone implant could induce corneal complications, such as corneal edema and corneal decompensation and might lower the corneal endothelial cell even if immediately removed. We report a case of corneal edema, which was induced by anterior migration of a fragmented dexamethasone implant and recovered with immediate surgical removal.

RESUMEN

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.

RESUMEN

PURPOSE: To elucidate the clinical manifestations of cytomegalovirus (CMV) endotheliitis, and evaluate the outcomes of treatment in CMV endotheliitis. METHODS: We reviewed the medical records of 7 patients (8 eyes) who were diagnosed with CMV endotheliitis via a polymerase chain reaction (PCR) of aqueous humor and were treated with ganciclovir. RESULTS: Eight eyes of 7 patients were followed for a mean of 17.8 months. One patient had bilateral corneal endotheliitis. All eyes had coin-shaped keratoprecipitates and mild anterior chamber inflammation (1+~2+). All eyes had an absence of anterior segment inflammation 3 weeks after ganciclovir treatment. Following treatment, the mean visual acuity improved significantly from 0.60 ± 0.40 (log MAR) at baseline to 0.18 ± 0.18 (log MAR) at last follow-up. The mean intraocular pressure (IOP) decreased significantly from 30 mm Hg at baseline to 12 mm Hg at last visit. Two eyes had a recurrence of corneal endotheliitis, where one underwent penetrating keratoplasty and the other was treated with intravitreal ganciclovir injection. CONCLUSIONS: Patients with increased IOP and coin-shaped keratoprecipitates are suspected to have CMV endotheliitis, and PCR of aqueous humor is needed to diagnose CMV endotheliitis. More than 6 weeks of ganciclovir treatment might be effective for CMV endotheliitis and may help prevent recurrence.

RESUMEN

PURPOSE: To report a case of phacoanaphylactic uveitis presenting as endophthalmitis. CASE SUMMARY: A 77-year-old woman presented with sudden visual disturbance and painful red right eye. She did not have a history of trauma or surgery in her right eye. Her best corrected visual acuity was hand movement in the right eye and log MAR 0.22 in the left eye; intraocular pressure was 27 mm Hg in the right eye and 15 mm Hg in the left eye. Slit-lamp examination revealed corneal edema and prominent inflammation with hypopyon in the anterior chamber. B-scan showed vitreous opacity behind the lens. Based on the diagnosis of endophthalmitis, anterior chamber paracentesis and irrigation were performed. After irrigation, a hypermature cataract with intact anterior capsule was observed. Therefore, we performed extracapsular cataract extraction and intravitreal antibiotics injection. Gram staining of the aqueous humor revealed numerous macrophages filled with lens protein but no organisms. She was treated with hourly topical corticosteroid and an antibiotic agent. One month later, the anterior chamber is clear, and the cultures remained negative. CONCLUSIONS: We report a case of spontaneous phacoanaphylactic uveitis presenting as endophthalmitis in a patient with no history of eye trauma or surgery.

RESUMEN

PURPOSE: To describe the change of lacrimal gland volumes in Korean patients with thyroid-associated ophthalmopathy (TAO) via computed tomography (CT). METHODS: A retrospective review of CT images from 217 TAO patients and 135 control subjects was performed. The TAO patients were diagnosed between May 2005 and May 2014 and had a CT performed on initial presentation (330 orbital CT scans). These images were compared with 270 orbital CT scans from the control group, obtained between May 2013 and May 2014. An open source DICOM viewer was used to calculate the volume of the lacrimal gland. RESULTS: The mean volume of the lacrimal gland in TAO patients was 0.816 cm³ in the right orbit (standard deviation [SD], 0.048) and 0.811 cm3 in the left orbit (SD, 0.051), with no significant difference between right and left (p = 0.192). However, significant differences were observed between TAO patients and healthy individuals (p < 0.001). There was no significant difference between mean lacrimal gland volumes of males (0.812 cm³; SD, 0.037) and females (0.816 cm³; SD, 0.029) (p = 0.513). There was a negative correlation between gland volume and age in TAO patients (Pearson r = -0.479, p = 0.00). The subjective tearing (right: r = 0.244, p = 0.018; left: r = 0.226, p = 0.024), corneal superficial punctate keratopathy (right: r = 0.192, p = 0.040; left: r = 0.206, p = 0.036), and exophthalmometry (right: r = 0.182, p = 0.032; left: r = 0.180, p = 0.046) correlated with lacrimal gland volume. CONCLUSIONS: This study is the first to use CT images to calculate the lacrimal gland volume of Korean TAO patients. In TAO patients, the lacrimal gland volume was notably increased compared to control subjects. The lacrimal gland volume decreased with age, but there was no difference between gender and no difference between left and right. The lacrimal gland volume correlated with subjective tearing, corneal superficial punctate keratopathy and exophthalmometry.

RESUMEN

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.

RESUMEN

PURPOSE: To report the long-term follow-up results after cyclocryotherapy, applied to the 3-o'clock and 9-o'clock positions in blind refractory glaucoma patients. METHODS: We retrospectively reviewed the charts of 19 blind patients, and a total of 20 eyes with refractory glaucoma who were treated with cyclocryotherapy. Cyclocryotherapy treatments were performed using a retinal cryoprobe. The temperature of each cyclocryotherapy spot was -80degrees C and each spot was maintained in place for 60 seconds. Six cyclocryotherapy spots were placed in each quadrant, including the 3-o'clock and 9-o'clock positions. RESULTS: The mean baseline pretreatment intraocular pressure (IOP) in all eyes was 50.9 ± 12.5 mmHg, which significantly decreased to a mean IOP at last follow-up of 14.1 ± 7.1 mmHg (p < 0.001). The mean number of antiglaucoma medications that patients were still taking at last follow-up was 0.3 ± 0.6. Devastating post-procedure phthisis occurred in only one eye. CONCLUSIONS: Cyclocryotherapy, performed at each quadrant and at the 3-o'clock and 9-o'clock position, is an effective way to lower IOP and, thus, is a reasonable treatment option for refractory glaucoma patients who experience with ocular pain and headaches.

RESUMEN

Infectious scleritis by Pseudomonas aeruginosa is a well-known vision-threatening disease. In particular, scleral trauma following pterygium surgery may increase the risk of sclera inflammation. Surgical debridement and repair is necessary in patients who do not respond to medical treatments, such as topical and intravenous antibiotics. We reports herein the effectiveness of an autologous perichondrium conchal cartilage graft for infectious scleritis caused by Pseudomonas aeruginosa. This procedure was performed on four eyes of four patients with infectious scleritis who had previously undergone pterygium surgery at Gyeongsang National University Hospital (GNUH), Jinju, Korea from December 2011 to May 2012. Pseudomonas aeruginosa was identified in cultures of necrotic scleral lesion before surgery. The conchal cartilage perichondrium graft was transplanted, and a conjunctival flap was created on the scleral lesion. The autologous perichondrium conchal cartilage graft was successful and visual outcome was stable in all patients, with no reports of graft failure or infection recurrence. In conclusion, autologous perichondrium conchal cartilage graft may be effective in surgical management of Pseudomonal infectious scleritis when non-surgical medical treatment is ineffective. Further studies in larger, diverse populations are warranted to establish the effectiveness of the procedure.

RESUMEN

PURPOSE: To report a case of Serratia marcescens keratitis presenting as radial keratoneuritis. CASE SUMMARY: A 15-year-old female who wore cosmetic and orthokeratology contact lenses but performed inadequate lens care visited our clinic with severe pain and visual disturbance in her left eye. On slit lamp examination, central corneal epithelial defect and stromal infiltration with radial keratoneuritis were observed. Based on clinical findings and past history, Acanthamoeba keratitis was highly suspected. The patient was treated with topical chlorhexidine 0.02% (Sigma-Aldrich Co., MO, USA) and moxifloxacin 0.5% (Vigamox(R), Alcon, TX, USA) per hour with 200 mg of oral itraconazol (Sporaone(R), LG, Seoul, Korea) once a day. Symptoms and corneal lesions did not improve after three days. After Serratia marsenscens was isolated from her contact lenses and solution, topical chlorhexidine 0.02% was discontinued, and intravenous ceftazidime (Tazime(R), Hanmi, Seoul, Korea) and fortified ceftazidime (50 mg/mL) eye drop was added. The corneal lesion dramatically improved, and after six months of follow-up, best-corrected visual acuity was 20/20 in the affected eye. CONCLUSIONS: Radial keratoneuritis can present not only in Acanthamoeba keratitis, but also in Serratia marsenscens keratitis. Confirmation of the isolated organism is useful when treating radial keratoneuritis.

RESUMEN

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.
