ABSTRACT Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern in the lens. The total amount exceeds 2.000g (significant for the ocular alterations described) considering the patient's daily dosage of chlorpromazine of 300mg for ten years. After performing complete ophthalmic evaluation and discarding other causes for the ocular deposits, we diagnosed a secondary corneal deposit and cataract due to the use of chlorpromazine. This case reinforces the importance of periodic follow-up with an ophthalmologist for chlorpromazine users to trace ocular changes, heeding the exposure time and its dosage.


RESUMO A clorpromazina é uma medicação muito empregada na psiquiatria para tratamento de psicoses, especialmente em casos de esquizofrenia. Desde 1964 existem artigos publicados que correlacionam o uso dessa medicação com o aparecimento de alterações oculares. Neste trabalho, relatamos o caso de um paciente de 65 anos com efeitos oculares devido à terapia de longo prazo com clorpromazina. A biomicroscopia de ambos os olhos apresentou depósitos granulares difusos e de cor marrom, mais proeminente ao nível do estroma profundo e do endotélio da córnea, além de depósitos castanhos subcapsulares anteriores centrais em um padrão estrelado no cristalino. Considerando a dose diária de clorpromazina de 300mg por 10 anos usada pelo paciente, a quantidade total ultrapassa 2.000g (dose considerada significativa para as alterações oculares descritas). Após avaliação oftalmológica completa e descartado outras causas desses depósitos oculares, foram diagnosticados depósito corneano e catarata secundários ao uso de clorpromazina. O caso apresentado reforça a importância do acompanhamento oftalmolÓgico periÓdico de usuários de clorpromazina para o rastreio de alteraçÕes oculares, atentando-se ao tempo de exposição à droga e à posologia da mesma.

PURPOSE: To report a case of macular edema and retinal vasculitis treated with intravitreal dexamethasone implantation in a Behcet's disease patient after cataract surgery. CASE SUMMARY: A 26-year-old male with Behcet's disease, without recurrence of uveitis for 3 months, underwent phacoemulsification and posterior chamber intraocular lens implantation for a cataract in the left eye. The preoperative best corrected visual acuity (BCVA) of the left eye was 0.15. At day 1 after surgery, his BCVA was 0.4, and slit lamp examination of his left eye revealed a mild anterior chamber reaction. At 1 week after surgery, he presented with left vision impairment, his BCVA was 0.04, and mild inflammation was observed in both the anterior chamber and the vitreous in his left eye. Unilateral macular edema was confirmed with optical coherence tomography, and fluorescein angiography revealed retinal vasculitis on the fovea and peripheral retina. Intravitreal dexamethasone implantation was performed in his left eye, 1 month after treatment, the macular edema and retinal vasculitis had improved, and the BCVA of his left eye was 0.8. CONCLUSIONS: In patients with Behcet's disease, intravitreal dexamethasone implantation can be an effective treatment option for macular edema and retinal vasculitis after cataract surgery.

PURPOSE: We report a case of toxic keratoconjunctivitis resulting from the self-application of human breast milk as a traditional folk remedy for allergic conjunctivitis. CASE SUMMARY: An 82-year-old woman presented with pain and conjunctival hyperemia in the right eye that had been worsening for three days. Two months previously, she was treated with antiallergic eye drops for allergic conjunctivitis at another eye clinic. However, the symptoms did not improve. She applied her daughter-in-law's breast milk into her right eye as a folk remedy for three days. The pain and conjunctival hyperemia worsened. At the initial visit, her corrected visual acuity was 0.3 in the right eye. Slit lamp examination demonstrated conjunctival hyperemia, punctate epithelial erosion at the central cornea, corneal keratic precipitates and white-colored deposits in the peripheral cornea combined with irregularly shaped small nodules. There was no anterior chamber inflammation. There was no medical history of rheumatoid arthritis or tuberculosis. Blood tests for serum and other infectious and inflammatory levels for infection and inflammatory markers were performed followed by application of topical steroids and antibiotics with artificial tears. After 3 weeks of treatment, conjunctival hyperemia and corneal deposits had almost resolved and best-corrected visual acuity improved to 1.0. CONCLUSIONS: The self-application of human breast milk may cause toxic keratoconjunctivitis. Therefore, efforts should be made, actively, to inform and educate the elderly in rural areas not to use human breast milk as a folk remedy.

PURPOSE: Congenital double puncta are usually unilateral, and the accessory punctum exists on the medial side in a slit configuration that is distinct from the shape of the normal punctum. We report a case of an unusual case of double lacrimal puncta which the lateral, rather than the medial, punctum was judged to be the accessory punctum. CASE SUMMARY: A 39-year-old male patient with no underlying disease and no ophthalmologic history visited our clinic with right eye epiphora of 2 weeks duration. On slit lamp examination, double puncta were observed in the right lower eyelid and the remaining puncta were normal. On lacrimal syringing test and dacryocystography were performed and revealed incomplete obstruction with partial narrowing of the nasolacrimal duct. Silicone tube intubation was performed through the right lower medial punctum and symptoms improved postoperatively. CONCLUSIONS: The present case is an unusual case of double lacrimal puncta which has not been reported in Korea. Unlike the previous literature, the lateral, rather than the medial, punctum was judged to be the accessory punctum. Because accessory punctm can be present on the lateral side, it is necessary to distinguish between the accessory punctm and the main punctum through the accurate dacryocystography and lacrimal syringing test for the treatment of the patient.

PURPOSE: We report two cases of uveo-meningeal syndrome involving the retina, uvea, and optic disc in both eyes after viral meningitis. CASE SUMMARY: A 16-year-old female was referred to our department with blurred vision in both eyes. She was hospitalized in the pediatric ward with viral meningitis. She showed a norma best-corrected visual acuity (BCVA) and normal intraocular pressure in both eyes, but had severe inflammation in the anterior chamber on slit lamp examination, and optic disc edema and multiple whitish lesions on fundus examination. She was treated with intravenous antibiotic injections and steroid eye drops. After close observation, inflammation in the anterior chamber, optic disc edema, and the multiple whitish lesions in the retina were improved. A 27-year-old male who was treated for viral meningitis at the neurology department was referred to us with blurred vision in both eyes. His BCVAs were 0.7 (right eye) and 0.6 (left eye). The intraocular pressure was normal in both eyes. Slit lamp examination revealed inflammation in the anterior chamber and optic disc edema, and a fundus examination revealed multiple infiltrations. He received treatment for presumed herpes virus infection. After close observation, inflammation in the anterior chamber, optic disc edema, and multiple infiltrations with hemorrhage in the retina were improved. CONCLUSIONS: Clinicians should consider the possibility of uveo-meningeal syndrome, which can cause inflammation in the uvea,retina, and optic disc simultaneous with viral meningitis accompanying blurred vision.

PURPOSE: To report a case of corneal and lenticular pigmentation after prolonged clozapine therapy. CASE SUMMARY: A 56-year-old male visited our hospital with a progressive decline in vision that affected both eyes. He had a history of schizophrenia. He was being treated with 200 mg clozapine and 1 mg lorazepam daily, and had been treated with clozapine for 5 years. At the first visit, his best-corrected-visual acuity was 20/32 in both eyes. Slit lamp examination of the corneas showed bright, fine, grayish-brown deposits on the endothelium, and on dilation, bilateral central stellate opacity of the anterior portion of the lens capsule was revealed. CONCLUSIONS: Clozapine may induce corneal and lenticular pigmentation and thus may lead to a decline in vision. Patients on long-term clozapine therapy should be considered for regular ophthalmic review.

PURPOSE: We report two cases of intraocular lens (IOL) pupillary optic capture following IOL scleral fixation treated with argon laser iridotomy. CASE SUMMARY: (Case 1) A 69-year-old man presented with suddenly decreased visual acuity of the left eye. The best-corrected visual acuity was finger count (FC) 30 cm in the left eye. Slit lamp examination revealed subluxation of the left eye IOL. An IOL scleral fixation and anterior vitrectomy were performed and no specific findings were observed. During the follow-up period, pupillary optic capture was repeated without specific causes, such as trauma, or IOL decentration thus, argon laser iridotomy was performed. (Case 2) A 77-year-old man presented with a 3-day history of congestion of the left eye and decreased visual acuity. Best-corrected visual acuity was 0.4 logarithm of the minimum angle of resolution (logMAR) in the left eye. Slit lamp examination revealed subluxation of the left eye IOL. An IOL scleral fixation and anterior vitrectomy were performed, and no specific findings were observed. During the follow-up period, pupillary optic capture was found, and IOL repositioning and argon laser iridotomy were performed. CONCLUSIONS: Laser iridotomy can be used to prevent recurrence of pupillary optic capture in eyes with IOL scleral fixation without decentration or distortion.

PURPOSE: To report the surgical technique to remove a chestnut thorn through a corneal incision. CASE SUMMARY: A 54-year-old female visited our clinic complaining of a sudden foreign body sensation and conjunctival injection in her left eye after picking chestnuts 4 days prior to her visit. Visual acuity of both eyes was 1.0 and the intraocular pressures were within normal limits. Slit lamp examination revealed that a chestnut thorn had deeply penetrated the left corneal stroma and a small number of inflammatory cells were observed in the anterior chamber. There was no corneal defect stained with fluorescein and the Seidel test was negative. A corneal foreign body comprised of a chestnut thorn and its remnants was diagnosed and emergency surgery was performed. A partial corneal incision was made along the foreign body and the exposed foreign body was easily and completely removed. The patient was treated with topical antibiotics after surgery and no complication was observed during a follow-up period of 3 months. CONCLUSIONS: In the case of a corneal foreign body comprised of a chestnut thorn, the foreign body with its remnants were easily removed by performing a partial corneal incision.

PURPOSE: To report polymicrobial keratitis involving Pseudomonas aeruginosa, Acinetobacter baumannii, and Ochrobactrum anthropi. CASE SUMMARY: A 53-year-old female complained of pain and secretion in her right eye, which started 6 weeks before her visit. She applied steroid ointment, which was received from the dermatologist, to her eyelid 7 days prior to her visit but this treatment worsened her symptoms. At the initial visit, the visual acuity of the right eye was light perception, and purulent secretions were observed. Using a slit lamp, severe conjunctival hyperemia, hypopyon, and a ring-shaped central corneal ulcer were observed. The anterior chamber and fundus were not observed due to corneal lesions but ultrasonography showed no intraocular inflammation. Infectious keratitis was suspected and cultured by corneal scraping. During the incubation period, 0.5% moxifloxacin, 2% voriconazole, and 1% cyclopentolate were administered. A total of 400 mg of moxifloxacin and 100 mg of doxycycline were given orally. In the primary culture, Pseudomonas aeruginosa and Acinetobacter baumannii were identified so 5% ceftazidime, which was sensitive for the antibiotic susceptibility results was further instilled. Thereafter, the keratitis improved but the keratitis again worsened while maintaining the topical treatment. A secondary culture was positive for Ochrobactrum anthropi. Treatment with 1.4% gentamicin, which was sensitive for the antibiotic susceptibility test was added and the keratitis improved. A conjunctival flap was performed because of the increased risk of perforation. CONCLUSIONS: We report polymicrobial keratitis involving Pseudomonas aeruginosa, Acinetobacter baumannii, and Ochrobactrum anthropi for the first time in the Republic of Korea.

PURPOSE: To report a case of a Corynebacterium macginleyi-infected corneal ulcer of a patient who had been treated for conjunctivitis for more than 3 months. CASE SUMMARY: A 72-year-old female was transferred from a private ophthalmic clinic for evaluation of herpetic keratitis with progressive corneal edema and infiltration in the left eye. She had a history of conjunctival hyperemia and eyeball pain in her left eye 3 months prior to her visit. She was treated with levofloxacin eye drops and acyclovir ointment (Herpesid®, Samil, Co., Ltd. Seoul, Korea). On slit lamp examination, 5.4 × 4.0 mm corneal epithelial defects and stromal infiltrations were observed in the upper to central cornea, and endothelial keratic precipitates were found. Gram positive bacteria were detected on Gram staining and Corynebacterium macginleyi was identified on bacterial cultures from the conjunctiva and cornea. She was treated with topical vancomycin eye drops. After 3 months of treatment, the corneal ulcer was completely resolved, leaving mild superficial opacity on the cornea. CONCLUSIONS: While Corynebacterium macginleyi, normal flora of the conjunctiva, is considered a major causative agent for conjunctivitis and blepharitis, Corynebacterium macginleyi should also be considered a possible cause of slowly progressive keratitis in patients with chronic conjunctivitis.

PURPOSE: To compare the efficacy and complications of scleral fixation of posterior chamber intraocular lens (IOL) and retropupillary fixation of iris claw IOL for dislocated IOL or aphakia without sufficient capsular support. METHODS: This retrospective study was comprised of 17 eyes of 16 patients undergoing scleral fixation and 14 eyes of 13 patients undergoing retropupillary fixation from August 2013 to June 2018. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), slit lamp examination, corneal topography, refractive indices, corneal curvatures, corneal endothelial cell density, and complications of both groups were examined preoperatively and 1 day, 1 week, 1 month, 2 months, and 6 months postoperatively. RESULTS: Six months after the operation, UCVA and BCVA improved in both groups; however, there were no significant differences between the two groups (UCVA, p = 0.162; BCVA, p = 0.418). IOP was temporarily higher in the scleral fixation group at one day postoperatively (p = 0.023). The mean absolute prediction error was smaller in the retropupillary iris fixation group at 6 months postoperatively (p = 0.034). Postoperative total astigmatism, corneal astigmatism, and corneal endothelial cell density were not significantly different between the two groups. CONCLUSIONS: The retropupillary iris fixation group did not show significant improvement in visual acuity compared with the scleral fixation group. However, the retropupillary iris fixation group provided better mean absolute prediction error and a low risk of postoperative increase in IOP compared with the scleral fixation group. Retropupillary fixation of iris claw IOL is a promising option for scleral fixation of posterior chamber IOL for dislocated IOL or aphakia without sufficient capsular support.

PURPOSE: We report a case of infectious keratitis caused by Shewanella putrefaciens in a patient after fishing. CASE SUMMARY: A 75-year-old male with no underlying disease other than hypertension was admitted to our hospital because of decreased visual acuity and congestion in his left eye for 2 weeks. At the first ophthalmic examination, the best-corrected visual acuity (BCVA) of the left eye was counting fingers. Slit lamp examination showed stromal infiltrates with 2.0 × 2.0 mm corneal epithelial defects, endothelial inflammatory plaques and 1 mm height hypopyon with severe inflammation in the anterior chamber. Bacterial culture tests were performed by corneal scraping, which were positive for Shewanella putrefaciens, followed by treatment with moxifloxacin and ceftazidime topical antibiotics. After 2 months of treatment, the BCVA of the left eye improved to 0.4 and the corneal lesion clinically improved with residual mild stromal opacity. CONCLUSIONS: Shewanella putrefaciens should be considered as a causal pathogen of infectious keratitis in patients after fishing. We report a case of infectious keratitis caused by Shewanella putrefaciens, which has never previously been reported in the Republic of Korea.

Fabry disease (FD) is an X-linked, recessively inherited, rare, progressive, disorder of glycosphingolipid metabolism affecting multiple organs resulting in organ dysfunction. It is rare to find only one FD affected subject with a de novo mutation. Here we report a case of a 41-year-old Asian male diagnosed with de novo FD. Comprehensive ophthalmological evaluation was performed using slit lamp, color fundus photography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography. On slit lamp examination, cornea verticillata and slightly tortuous, and aneurysmal dilatation of inferior bulbar conjunctival vessels were observed. Other imaging modalities showed unremarkable findings. Cornea verticillata and inferior bulbar conjunctival vascular abnormalities may be detected earlier than other ocular abnormalities in de novo FDs like hereditary FDs.

PURPOSE: To compare the surgical outcomes between trabeculectomy with a collagen matrix (Ologen®) insertion and conventional trabeculectomy. METHODS: An ophthalmic examination, including tonometry and a slit lamp examination, was performed 1 week, 2 weeks, 1 month, 2 months, 4 months, 6 months, and 12 months postoperatively in glaucoma patients who underwent a trabeculectomy using Ologen® (experimental group) or a conventional trabeculectomy (control group). Clinical features including success rate and complications were compared between the two groups. RESULTS: In 21 eyes of the experimental group and 42 eyes of the control group, the success rates were 76% and 69%, respectively (p = 0.554). Needling with subconjunctival 5-fluorouracil injection or laser suture lysis of the scleral flap was required in three eyes (14.3%) in the experimental group and 18 eyes (42.9%) in the control group (p = 0.023). The types of complications differed, although the total number of complications did not differ between the two groups (23.8% vs. 19.0%, respectively; p = 0.745). The most common complication in the experimental group was an encapsulated bleb, which occurred in three eyes (14.3%), whereas an avascular bleb occurred in three eyes (7.1%) in the control group. CONCLUSIONS: The success rate of trabeculectomy with Ologen® was comparable to that of conventional trabeculectomy. However, postoperative interventions were less commonly required after trabeculectomy with Ologen®, and the complications differed between the groups. When choosing the surgical method and examining the postoperative condition, these differences should be considered.

PURPOSE: In the present study, two cases of intraoperative acute opacification of hydrophilic intraocular lens were reported. CASE SUMMARY: (Case 1) A sixty-seven year-old female presented with chronic visual impairment. Slit lamp examination revealed nuclear cataract of the left eye. Cataract surgery for her left eye was performed. A hydrophilic intraocular lens was checked before implantation and no defect was noted. Immediately after the implantation of the intraocular lens, acute whitish opacification of the intraocular lens occurred. However, the intraocular lens was not explanted, and the opacification cleared after one day. (Case 2) A 65 year-old male presented with chronic visual impairment of the left eye. Nuclear cataract of his left eye was noted, and he went through cataract surgery of the left eye. After the implantation of intraocular lens, acute whitish opacification of the intraocular lens was noted but it disappeared a day after. CONCLUSIONS: Intraoperative acute opacification of intraocular lens seems to occur due to radical temperature change. There is no need to remove or exchange the intraocular lens as opacification tends to clear within a day. No structural or mechanical change of intraocular lens was noted after opacification. Careful management of temperature for intraocular lens storage is necessary for prevention of intraoperative intraocular lens clouding.

PURPOSE: We report two cases of corneal edema in patients who presented with bilateral blurry vision due to vaporized amines while working in a polyurethane processing plant. CASE SUMMARY: A 28-year-old male presented with bilateral blurred vision. His work involved solidifying polyurethane liquid and he often found himself exposed to polyurethane heat and gas. On examination, the patient's uncorrected visual acuity (UCVA) was 20/40 (right) and 30/50 (left). A slit lamp examination revealed subepithelial microbullae in both eyes. The central corneal thickness (CCT) was also increased in both eyes, measuring 698 µm (right) and 672 µm (left). After prescribing 0.5% moxifloxacin and, 1% fluorometholone eye drops for 3 days in both eyes, the UCVA recovered to 20/40 (right) and 20/20 (left). The CCT decreased to 644 µm (right) and 651 µm (left), and the microbullae improved significantly in the left eye. The second patient was a 34-year-old female who presented with bilateral decreased visual acuity while at work. She worked in a factory that produced car seat filling. Her UCVA was 20/25 (right) and 20/20 (left). The CCT by specular microscopy was 537 µm (right) and 541 µm (left). On slit lamp examination, both eyes demonstrated bilateral central subepithelial edema. The patient did not attend any follow-up outpatient appointments after the initial presentation. CONCLUSIONS: Exposure to vaporized amines such as polyurethane may causereversible corneal toxicityeven without direct contact. Further consideration should be given to ocular safety and protection from amine compounds in the industrial field.

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.

PURPOSE: To report a case of isolated conjunctival lymphangioma mimicking a recurrent conjunctival cyst. CASE SUMMARY: A 39-year-old male with a conjunctival cyst in the right eye lasted for 1 month visited our hospital. He had previously undergone aspiration of the cyst at another hospital 1 week before visiting our hospital. However, the cyst recurred, and he was referred to our hospital. On slit lamp biomicroscopy, yellow-colored turbid fluid and a hemorrhage were observed in the conjunctival cyst, but no specific finding was found in the fundus photography. The patient was initially treated with topical antibiotics and steroids. Three weeks later, absorption of the hemorrhage was noted, but there was no change in the size of the cyst. Therefore, surgical removal and histological examination of the cyst were performed. The histological examination revealed that the lesion was positive for CD 31 and D2-40, and the cyst was diagnosed as a cystic conjunctival lymphangioma. Thereafter, brain magnetic resonance imaging was performed to screen for orbital lymphangioma and systemic disease that could accompany a conjunctival lymphangioma. However, no specific findings were observed. There was no recurrence of the conjunctival cyst at 1 year and 6 months after surgical removal, and no other ophthalmic or systemic complication was observed. CONCLUSIONS: An isolated conjunctival lymphangioma is a rare lesion. In the diagnosis of lymphangioma, systemic examination is recommended for the identification of comorbid diseases, such as orbital lymphangioma.

PURPOSE: To report a case of multicentric Castleman disease that presented with scleritis. CASE SUMMARY: A 42-year-old male presented with decreased visual acuity in the left eye. Castleman disease had been diagnosed 21 months before and treated with systemic steroids and combined chemotherapy. Best-corrected visual acuity (BCVA) of the left eye was 0.02 and the intraocular pressure was 42 mmHg. Scleral edema and corneal edema were noted using a slit lamp examination. The anterior chamber cell was 2+ according to Standardization of Uveitis Nomenclature criteria. The fundus was invisible due to the anterior segment lesion. After one month, scleritis developed in the right eye and the patient complained of ocular pain. Topical steroids and non-steroidal anti-inflammatory drugs were prescribed. Due to recurrent scleritis and anterior uveitis, cataract extraction and laser iridectomy were performed on the left eye, and systemic steroids and the antimetabolite methotrexate were started. After 9 years of follow-up, all medications were stopped and there was no recurrence of inflammation, with a BCVA of 1.0 in both eyes. CONCLUSIONS: Treatment of a patient with scleritis accompanied with Castleman disease using systemic steroids and methotrexate resulted in a good prognosis.
