ABSTRACT
Although the advent of molecular-targeted drugs has improved the prognosis of various cancers, the long-term prognosis and side effects as the first-line therapy for metastatic choroidal tumors remain unclear. We describe a case in which the first-line therapy of osimertinib has shown long-term successful and minimum side effect responses for metastatic choroidal tumors in a patient with advanced-stage lung cancer. The patient was a 62-year-old man who complained of foggy vision and visual field defects in his left eye for 1 month. When he visited his local doctor, a serous retinal detachment was noted in the left eye, and he was referred to our hospital for further examination. The patient had no history of systemic disease. A fundus examination of his left eye showed a slightly elevated choroidal lesion along with the superior retinal vascular arcade. Optical coherence tomography showed a serous retinal detachment around the lesion. Fluorescein angiography showed that the site of the lesion had spotty and mottled hyperfluorescence in the early phase and ring hypofluorescence in the late phase. We suspected a metastatic choroidal tumor and performed a whole-body computed tomography scan, which indicated lung cancer and metastasis to the left iliac bone. The patient was referred to the department of respiratory medicine of our hospital, and after a thorough examination, a diagnosis of lung adenocarcinoma (stage IV-B, epidermal growth factor receptor [EGFR] gene mutation positive) was made. Treatment with osimertinib was initiated, and shrinkage of the primary tumor was observed. The elevated choroidal lesion and serous retinal detachment resolved after 2 months of treatment, and no recurrence was observed during the 20 months of treatment. The use of osimertinib as primary treatment for EGFR mutation-positive lung cancer was found to significantly reduce the size of metastatic choroidal tumors and to have a relatively long-lasting antitumor effect without serious ocular complications.
ABSTRACT
A higher serum vascular endothelial growth factor (VEGF) level can cause choroidal thickening in the choroid of patients with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. We aimed to determine whether fluctuations in serum VEGF levels affect choroidal vascular structures in patients with POEMS syndrome. This retrospective observational case series examined 17 left eyes of 17 patients with POEMS syndrome. Enhanced depth imaging optical coherence tomography (EDI-OCT) images were obtained, and serum VEGF levels were measured at baseline and 6 months after transplantation with dexamethasone (n = 6), thalidomide (n = 8), or lenalidomide (n = 3). EDI-OCT images were binarized using ImageJ software, and we calculated the areas of the whole choroid and the luminal and stromal areas. Subsequently, we determined whether the choroidal vascular structure had changed significantly between baseline and 6 months after treatment. Six months after treatment, serum VEGF levels and the whole choroid, luminal, and stromal areas had decreased significantly compared to the baseline values (all, P < 0.001). The mean luminal area to the whole choroidal area ratio at 6 months after treatment was 0.70 ± 0.03, which was significantly smaller than the ratio at baseline (0.72 ± 0.03; P < 0.001). Whole choroid and luminal area fluctuations were significantly positively correlated with fluctuations in serum VEGF levels (r = 0.626, P = 0.007 and r = 0.585, P = 0.014, respectively). Choroidal thickening induced by VEGF might be caused by increases in the choroidal vessel lumen area. These results may offer insights into the pathogenesis of POEMS syndrome and the role of serum VEGF in choroidal vascular structure, which may apply to other ocular diseases.

BACKGROUND: Werner syndrome is a rare, autosomal recessive disorder characterised by premature aging. It is a typical hereditary progeroid syndrome that can be difficult to diagnose owing to its rarity and the similarity of some of its symptoms, such as juvenile cataracts, to other common ophthalmologic conditions. Early onset of bilateral cataracts is currently used as the ophthalmological feature for Werner syndrome; however, ophthalmologists often find performing a detailed examination of the medical history and genetic testing for Werner syndrome at the time of an ophthalmologic consultation challenging. If a unique ocular finding was observed on ocular examinations in cases of juvenile bilateral cataracts, we could consider Werner syndrome as a differential diagnosis. CASE PRESENTATION: We documented the cases of three patients with Werner syndrome in whom thinning of the retina in the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) were observed using optical coherence tomography (OCT). Visual field tests revealed the loss of visual field mainly owing to glaucoma. The thinnig of the choroidal thickness (CT) in three patients was also observed using enhanced depth imaging (EDI)-OCT. CONCLUSIONS: Three patients have thinning of the RNFL, GCC, and choroidal thickness and the loss of visual field. These findings suggest the need for including Werner syndrome in the differential diagnosis when patients presenting with juvenile cataracts of unknown cause also show abnormal retinal and choroidal thinning in the OCT images.

Purpose: Blunt ocular trauma rarely results in optic nerve avulsion. Here, we report a case of incomplete optic nerve avulsion caused by the impact of a badminton shuttlecock. Observations: The patient was a 16-year-old healthy male. A badminton shuttlecock hit his right eye from a short distance. On his first visit to the local eye clinic, his visual acuity in the right eye was hand motion. About 4-mm hyphema in height was observed in the right eye. Three days after the injury, visual acuity improved to 20/50, but the intraocular pressure increased to 40 mmHg; hence, intraocular pressure (IOP)-lowering medication was initiated. Five days after the injury, although hyphema had decreased gradually, he noticed a worsening of vision and was referred to our department. In his right eye, visual acuity was reduced to finger-counting, IOP was 38 mmHg. Slit-lamp examination of the right eye revealed a dilated pupil, hyphema, and angle recession. Fundus examination revealed dilation of the central retinal vein and edematous changes around the optic nerve head. Optical coherence tomography showed a very deep depression of the optic nerve head and partial rupture of the optic nerve axons. B-mode ultrasonography showed hypolucency just posterior to the optic nerve head. Goldmann perimetry revealed a central visual field defect in the right eye. Computed tomography showed no signs of optic canal fracture. These findings suggest that incomplete optic nerve avulsion had occurred. We performed IOP-lowering and anti-inflammatory therapy. After treatment, visual acuity was restored to 20/50, and the deep depression of the optic nerve head recovered to an almost normal range. Conclusion and Importance: It was assumed that the impact of the badminton shuttlecock caused irreversible changes in the optic nerve head, but the visual function partially improved with IOP-lowering and anti-inflammatory therapy. Because eye injury in badminton can cause severe damage to visual function, every badminton player needs to wear an appropriate eye shield, and rules or guidelines to prevent untoward accidents are needed in badminton.
ABSTRACT
PURPOSE: To determine whether there is a significant correlation between the retinal sensitivity and the integrity of the ellipsoid zone (EZ) of the photoreceptors in eyes with myopic chorioretinal atrophy (CRA). We also determined the significance of the correlation between the retinal sensitivity and the retinal and choroidal thicknesses. METHODS: The medical records of 10 eyes of six subjects with myopic CRA were reviewed. The integrity of the EZ was determined in the spectral-domain optical coherence tomographic (OCT) images at 37 points of six scans corresponding to the locations where the retinal sensitivities were measured by MP-3 microperimetry. The mesopic retinal sensitivities were determined within the central 16°. The significance of the correlations between the integrity of the EZ and the mesopic retinal sensitivities was determined. The relationships between the retinal and choroidal thickness and the retinal sensitivity were also determined. RESULTS: The average age of the patients was 70.0 ± 6.7 years, and the average axial length of the eye was 29.2 mm. The mesopic sensitivities at the points where the EZ was present were significantly higher than those where the EZ was absent (p < 0.01). The mesopic sensitivity was significantly correlated with the retinal thickness (p < 0.01, r = 0.30) and the choroidal thickness (p < 0.01, r = 0.23). CONCLUSIONS: The significant correlation between the mesopic retinal sensitivity and the integrity of the EZ indicates that the mesopic sensitivities can be used to assess the integrity of the photoreceptors in eyes with myopic CRA.

OBJECTIVE: To investigate the difference in clinical course after the first optic neuritis (ON) between aquaporin-4 IgG-associated disorder (AQPAD) and myelin oligodendrocyte glycoprotein-IgG-associated disorder (MOGAD) METHODS: In this study, 31 eyes in 24 patients with AQPAD and 26 eyes in 18 patients with MOGAD were included. The clinical course for the first 6 months after the first ON was monitored by a retrospective cohort study. Best-corrected visual acuity (BCVA) was observed before the onset and at nadir, 2 weeks (2 W), 1 month (1 M), 2 months (2 M), 3 months (3 M) and 6 months (6 M). The decimal BCVA was converted to the logarithm of the minimal angle of resolution (logMAR) for statistical analyses. RESULTS: MOGAD eyes showed longer median number of days from ON onset to nadir (6.0 vs. 11.5, P = 0.012) and to treatment (7.0 vs. 11.0, P = 0.020) than AQPAD eyes. The median logMAR was higher in AQPAD eyes than in MOGAD eyes at nadir (2.00 vs. 1.77, P = 0.050), 2 W (1.85 vs. 0.40, P = 0.001), 2 M (0.023 vs. - 0.079, P = 0.032) and 3 M (0.046 vs. - 0.079, P = 0.002). The median time to recovery of BCVA to 0.7 was longer in AQPAD eyes than in MOGAD eyes (44.0 vs. 21.0 days, P = 0.024), but that to BCVA 1.0 was not different between the two disorders (168.0 vs. 40.0 days, respectively, P = 0.056). CONCLUSION: Compared with MOGAD eyes, AQPAD eyes tended to show worse visual outcome even during the first ON episode.

PURPOSE: To determine the effects of cataract surgery on contrast visual acuity and retinal sensitivity in patients with retinitis pigmentosa. METHODS: Retinal sensitivity and contrast visual acuity were determined by microperimetry (MAIA) and contrast sensitivity acuity tester (CAT-CP), respectively, before and after cataract surgery. The significance of the correlations between visual acuity, retinal sensitivity, contrast visual acuity, improvements after surgery, and macular structure before and after cataract surgery was determined. RESULTS: Retinal sensitivity and contrast visual acuity were significantly improved after cataract surgery. The correlations among postoperative visual acuity, postoperative retinal sensitivities, and preoperative ellipsoid zone length were significant. The postoperative retinal sensitivity of the central 10° and the ellipsoid zone length was particularly significantly correlated. Preoperative contrast visual acuity and the amount of improvement and preoperative retinal sensitivity and the amount of improvement were significantly negatively correlated. The contrast visual acuity under both the 100% and 10% photopic and mesopic conditions improved significantly after cataract surgery. CONCLUSIONS: Cataract surgery in retinitis pigmentosa patients with preserved ellipsoid zones significantly improved retinal sensitivity and contrast visual acuity. Cataract surgery can be expected to improve retinal sensitivity and contrast visual acuity under various conditions, even if preoperative visual parameters are low, as long as the ellipsoid zone is preserved.
ABSTRACT
PURPOSE: To determine the effects of cataract surgery and preoperative factors on the vision-related quality of life (QOL) in patients with retinitis pigmentosa (RP). MATERIALS AND METHODS: This was a prospective, interventional study of 54 patients diagnosed with RP. The 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was used to determine the QOL before and after the cataract surgery. The correlations between the scores of the questionnaire and the best-corrected visual acuity (BCVA), macular structure, and degree of improvement of the NEI VFQ-25 scores were also determined. RESULTS: Statistically significant improvements were observed in the BCVA and all of the NEI VFQ-25 subscale scores except for color vision. The improvement of general vision was the largest. The postoperative BCVA of the better-seeing eye was more strongly and significantly correlated with the postoperative NEI VFQ-25 scores than that of the worse-seeing eye. All of the postoperative NEI VFQ-25 scores were significantly correlated with the length of the ellipsoid zone (EZ) of the photoreceptors. No significant correlation was found between the preoperative general vision, near vision, mental health scores, and EZ length. All of the preoperative NEI VFQ-25 scores except the social function and mental health scores were negatively and significantly correlated with the degree of improvement of the NEI VFQ-25 score. The EZ length was significantly correlated with the degree of improvement of the NEI VFQ-25 scores of the general vision, distance vision, mental health, dependency, and composite 9 scores. CONCLUSIONS: Cataract surgery can significantly improve the NEI VFQ-25 scores in RP patients. The EZ length can be used to predict the postoperative VFQ scores. We conclude that the NEI VFQ-25 is a useful method to evaluate the impact of cataract surgery on the BCVA in patients with RP.

BACKGROUND: The purpose of this study is to determine the epidemiology of tumors of the ocular adnexa and orbit in Japan. METHODS: We conducted a retrospective study on the histopathological reports in the medical records of the Chiba University Hospital from April 2009 to March 2019. Three hundred and seventy two records were examined. In addition, we examined the annual changes in the major types of tumors including malignant lymphomas and IgG4-related diseases (IgG4-RDs). RESULTS: There were 270 conjunctival or eyelid tumors with 166 benign and 104 malignant. There were 102 orbital tumors with 55 benign, 47 malignant tumors, and 21 cases of IgG4-RDs. Ten cases of adenoma (2.7%), another benign tumor, was also diagnosed. The major malignant tumors were malignant lymphoma in 74 cases, sebaceous gland carcinoma (SGC) in 28 cases, basal cell carcinoma in 15 cases, and squamous cell carcinoma in 8 cases. The SGCs were the most common malignant eyelid tumor at 54%. Among the malignant lymphomas, extranodal marginal zone lymphomas of the mucosa-associated lymphoid tissue type, MALT lymphomas, was the most common at 51 cases and the second most common was the diffuse large B-cell lymphoma at 11 cases. The ratio of MALT lymphomas to that of all malignant lymphomas increased significantly with years. The serum IgG4 values were measured more often in the last 5 years (70%) than in the former 5 years (33%). CONCLUSIONS: We conclude that malignant lymphoma is a major malignant tumor in Japan and pathological biopsies should be done proactively to prevent missing IgG4-positive MALT lymphomas.

We report a case of ocular toxoplasmosis that developed a full-thickness macular hole (FTMH) which was successfully treated by pars plana vitrectomy combined with an inverted internal limiting membrane (ILM) flap. A 49-years-old Japanese man was aware of blurred vision in his right eye. Slit-lamp biomicroscopy, ophthalmoscopy, and optical coherence tomography (OCT) of the right eye showed that there was a grayish-white subretinal lesion at the macula accompanied by retinal exudation and mild vitreous flare and iritis. An increase in the level of serum IgM for toxoplasma led to a diagnosis of ocular toxoplasmosis. He developed a FTMH adjacent to the lesion 2 weeks after administering sulfamethoxazole/trimethoprim, and his decimal visual acuity was 0.15. Because the FTMH remained 3 months after the resolution of inflammation and his metamorphopsia persisted, vitrectomy with an inverted ILM flap was performed. After the surgery, the visual acuity improved to 0.2 with the closure of the FTMH confirmed by OCT. A FTMH in an eye with ocular toxoplasmosis was successfully closed by vitrectomy with an inverted ILM flap.
ABSTRACT
PURPOSE: To report a case in which an internal limiting membrane (ILM) flap that was used to cover an idiopathic macular hole (MH) during pars plana vitrectomy (PPV) with the inverted internal limiting membrane flap technique partially detached from the retina. Most interestingly, the flap fell back spontaneously to re-cover the MH. OBSERVATIONS: A 70-year-old woman presented with a full-thickness MH, and her vision was 20/400. She underwent PPV with an inverted ILM flap and air tamponade. When the intraocular gas was absorbed, the ILM flap detached but was held to the retina where it had not been peeled and the MH was open. Her visual acuity at this time was 20/400. The patient did not want further treatment and was followed by observation alone. At three months after the initial surgery, the ILM flap was noted to have spontaneously re-covered the MH, and her visual acuity improved to 20/200. At 6 months after the re-covering, the flap remained over the MH and the visual acuity remained at 20/200. CONCLUSIONS AND IMPORTANCE: Surgeons should be aware that it is possible for an ILM flap created by the inverted ILM flap technique to partially detach from the retina after the tamponade gas is resorbed. Most importantly, the flap can return to re-cover the MH spontaneously.
ABSTRACT
PURPOSE: To report a case of persistent fetal vasculature (PFV) with a retinal detachment that worsened after cataract surgery. Pars plana vitrectomy (PPV) was performed which reduced the vitreous traction and reattached the retina. Observations. A 20-year-old Myanmarese woman presented with a mature cataract, and her vision was light perception. She underwent uneventful cataract surgery with implantation of an intraocular lens. Her visual acuity improved to 20/200 immediately after the surgery. However, fibrotic tissue was observed between the optic nerve head and the posterior capsule. She was diagnosed with PFV, and she was followed without any intervention. One and a half years after the cataract surgery, she had an advanced retinal detachment which extended over the inferior two quadrants. Her vision deteriorated to 20/400. She underwent PPV, and the PFV tissue was removed which resulted in the reattachment of the retina. The visual acuity improved to 20/60. CONCLUSIONS: Surgeons should be aware that it is possible to worsen a retinal detachment after cataract surgery in the eyes with PFV. A simple technique to release the anterior-posterior traction by the PPV was sufficient to achieve the reattachment of the retina.
ABSTRACT
PURPOSE: To report the outcomes of pars plana vitrectomy in cases with breakthrough vitreous hemorrhage (VH) secondary to exudative age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy. We also investigated the relationship between the preoperative b-mode ultrasonographic findings and the postoperative visual acuity to determine if the ultrasonographic findings can predict the surgical outcome after pars plana vitrectomy. METHODS: This was a retrospective, interventional, case series. Twenty eyes of 20 patients were studied. The associations between the pre- and intraoperative factors and the final best-corrected visual acuity (BCVA) were determined. Recombinant tissue-plasminogen activator (tPA) was used in cases with massive hemorrhagic retinal detachment. RESULTS: Ten eyes with polypoidal choroidal vasculopathy (PCV), two eyes with choroidal neovascularization (CNV), and eight eyes with an unknown type of AMD were studied. The mean BCVA was 0.73 ± 0.57 logarithm of the minimum angle of resolution (logMAR) units before developing the VH, 2.25 ± 0.45 logMAR units before the surgery, and 1.52 ± 0.87 logMAR units after the surgery. The BCVA improved significantly after the surgery (P = 0.004) but was significantly worse than that before developing the VH (P = 0.012). The cases of PCV had better final BCVA than cases of CNV (P = 0.043, Mann-Whitney test). The preoperative presence of a subretinal elevation at the macula detected by ultrasonography was significantly associated with a poorer final BCVA (P = 0.031). CONCLUSIONS: Vitrectomy significantly improved visual function in the eyes with VH associated with exudative AMD. The eyes with PCV and no macular subretinal elevation on ultrasonography had a better visual prognosis.

PURPOSE: To compare the outcomes of vitrectomy with removal of an idiopathic epiretinal membrane (ERM) in the myopic eyes with long axial length (AL) to that in the eyes with normal AL. METHODS: This was a retrospective, observational, case-control study. Fifty-six eyes of 56 patients with an idiopathic ERM were studied. Twenty-eight of these eyes had an axial length longer than 26.0 mm (Group A), and the other 28 eyes had axial lengths < 26.0 mm (Group B). The age and visual acuity of the two groups were not significantly different. All subjects were treated by vitrectomy and peeling of the ERM with a 25- or 27-gauge system. The postoperative best-corrected visual acuity (BCVA) and optical coherence tomographic findings were determined at 3 and 6 months postoperatively. RESULTS: The mean BCVA improved from 0.35 ± 0.25 to 0.15 ± 0.25 logMAR units in the eyes with the long AL and from 0.35 ± 0.25 to 0.10 ± 0.21 logMAR units in the eyes with normal AL at 6 months postoperatively (both P < 0.001). The postoperative BCVA was not significantly different between the two groups at 6 months (P = 0.221). The central macula was thinner in the eyes of Group A than Group B (P < 0.001). The restorations of the ellipsoid zone and the external limiting membrane were observed in both groups, but the interdigitation zone was less frequently restored in Group A (P < 0.001). CONCLUSIONS: Vitrectomy with the removal of the epiretinal membrane is effective in attaining a good BCVA even in the myopic eyes with long AL.

INTRODUCTION: To compare the morphological and visual outcomes after pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and flap removal to that with flap insertion in eyes with myopic macular-hole retinal detachment (MHRD). METHODS: Forty-six eyes of 45 patients with MHRD were studied. Eighteen eyes were treated by PPV with ILM peeling and flap removal and 28 eyes by flap insertion, respectively. The baseline characteristics and postoperative findings were compared between the 2 groups. RESULTS: The average age of the cases was 70.0 ± 8.5 years. The best-corrected visual acuity (BCVA) improved, from 1.51 ± 0.14 to 1.31 ± 0.20 logMAR units in the flap removal group, and from 1.20 ± 0.10 to 0.88 ± 0.10 logMAR units in the flap insertion group (p = 0.049). A significantly larger number of MHs were closed in the flap insertion group (96 vs. 50% in the removed group; p < 0.001). Restoration of the ellipsoid zone (EZ) and external limiting membrane (ELM) was also better in the flap insertion group than in the flap removal group (EZ 14 vs. 6%, p = 0.003; ELM 36 vs. 6%, p < 0.001). DISCUSSION: The technique of ILM peeling with flap insertion is more effective in closing the MH, and results in better BCVA and better restoration of the outer retinal microstructures than flap removal.

We present our findings in an atypical case of ocular syphilis with optic disc neovascularization that was treated with intravitreal bevacizumab and followed by multimodal imaging and electroretinography. A 29-year-old man presented with a chief complaint of night blindness of one-year duration. Our initial examination showed that an optic disc neovascularization was present, and the optical coherence tomographic (OCT) images showed a reduction in the length of the ellipsoid zone of both eyes. Fluorescein angiography showed leakage from the optic disc neovascular tissue, and the presence of nonperfused areas in the peripheral retina. Blood test was strongly positive for syphilis. He was administered oral amoxicillin and prednisolone. He was also treated with an intravitreal injection of bevacizumab which led to a rapid suppression of the neovascularization. However, panretinal photocoagulation had to be performed because OCT angiography and fluorescein angiography detected residual neovascularization. Although these treatments suppressed the activity of the ocular syphilis, electrophysiological improvements were not seen even 1 year after the initial treatment. OCT angiography and electroretinogram are useful techniques for monitoring the effectiveness of the treatments.
ABSTRACT
The purpose of this study was to evaluate the long-term effects of half-time photodynamic therapy (PDT) on the retinal sensitivity in eyes with chronic central serous chorioretinopathy (CSC). Twenty-two eyes of 22 patients with chronic CSC were studied. PDT was applied with full-dose verteporfin and half-time laser duration. The best-corrected visual acuity (BCVA) and retinal sensitivity in the central 2 and 10 degrees were evaluated at the baseline, and at 12 and 24 months after the half-time PDT. The retinal sensitivity was determined by Macular Integrity Assessment microperimetry (MAIA, Centervue, Padova, Italy). The results showed that the mean retinal sensitivities in the central 2 and 10 degrees were significantly improved at 12 months (25.6 ± 2.79 dB, median; 26.11 dB, 25.6 ± 2.25 dB, median; 25.65 dB, respectively; P < 0.001) and at 24 months (26.3 ± 2.62 dB, median; 27.38 dB, 26.6 ± 2.21 dB, median; 27.45 dB, respectively; P < 0.001) after the treatment compared to that at the baseline (19.2 ± 3.93 dB, median; 19.34 dB, 20.9 ± 2.92 dB, median; 20.9 dB, respectively). The BCVA was also significantly improved from 0.18 ± 0.19 median; 0.15 logarithm of the minimum angle of resolution (logMAR) units at the baseline to 0.07 ± 0.15 median; 0 logMAR units at 12 months (P < 0.001) and to 0.049 ± 0.16 median; -0.039 logMAR units at 24 months (P < 0.001). We conclude that half-time PDT results in a significant improvement of the mean central retinal sensitivity for at least 24 months in eyes with chronic CSC. Thus, half-time PDT is beneficial in resolving chronic CSC for a relatively long period.

We report two cases of chronic rhegmatogenous retinal detachment with a nonperfused peripheral retinal area. Case 1 was an 84-year-old woman who presented with a bullous retinal detachment of the inferior retina and a best-corrected visual acuity of 20/500. A small horseshoe tear was detected in the peripheral superior retina. Fluorescein angiography showed a wide area of nonperfused retina in the inferior retina. The retina was successfully reattached by scleral buckling surgery. Case 2 was a 40-year-old woman who presented with a shallow retinal detachment involving the macula. There were multiple retinal breaks at the pars plana that were secondary to blunt trauma. Fluorescein angiography revealed a wide area of nonperfused retina in the inferior peripheral retina. She underwent scleral buckling surgery, and the retina was successfully reattached. Our findings indicate that clinicians should examine the peripheral retina carefully especially with fluorescein angiography to search for nonperfused areas in eyes with chronic rhegmatogenous retinal detachment.
ABSTRACT
A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion. Her left vision was 20/50, and schisis was observed inferotemporally. She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane. Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery. However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers. She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion. After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery. The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.
ABSTRACT
A 37-year-old Japanese man had his right eye hit by a fist. His right eye developed hypotony maculopathy and secondary cataract, and his visual acuity decreased to 20/200 with an intraocular pressure of 4 mmHg. He underwent phacoemulsification and aspiration, implantation of the intraocular lens, and encircling with a silicone tire. His visual acuity improved to 20/20 and stable for more than one year postoperatively. The intraocular pressure in his right eye increased to 12 mmHg, and maculopathy was resolved entirely. It was suggested that an encircling buckle obstructed the uveoscleral outflow through the cyclodialysis and increased intraocular pressure. Concurrent cataract surgery and encircling was sufficient to improve the vision.
