Postoperative maxillary cyst (POMC) is relatively common complication among patients who underwent Caldwell-Luc surgery. Patients with POMC usually have no symptoms, although cyst extension can result in bone destruction or cystic infection with pain. The trigeminal nerve consists of the ophthalmic nerve, maxillary nerve, and mandibular nerve. Among these branches, the maxillary nerve runs to the lateral and frontal sides of the maxillary sinus wall. POMC can rarely lead to trigeminal neuropathy caused by cyst enlargement that compresses some branches of the trigeminal nerve. Recently, we experienced a case with trigeminal neuralgia due to POMC. The patient was successfully treated with inferior meatal antrostomy. We report this rare case with a literature review.

PURPOSE: To report a case of masked glaucomatous optic nerve head damage due to acute swelling in a primary open-angle glaucoma patient. CASE SUMMARY: A healthy 21-year-old male visited our clinic complaining of blurred vision in the right eye for 1 week. The intraocular pressure (IOP) was 60 mmHg, as measured by a Goldmann applanation tonometer. No specific anterior segment finding other than severe corneal edema was found on slit lamp examination. Maximum tolerated medical therapy was performed, and a further examination was done 1 day after the IOP lowering. No glaucomatous change in the optic disc or retinal nerve fiber layer was observed on fundus examination and optical coherence tomography (OCT), but the optic disc of the right eye was more hyperemic than that of the left eye. A superonasal visual field defect was also observed using automated perimetry. After treatment, the IOP was kept within the normal range using IOP-lowering eye drops. However, an inferonasal retinal nerve fiber layer defect was observed on fundus examination and OCT, and a superonasal scotoma was detected by perimetry.

Sarcoidosis is a granulomatous disease which frequently involves eyes and adnexal tissues. Its prevalence of ocular involvement is reported as about 20%, although it varies widely according to authors, from 12% to 73%. Ocular sarcoidosis is present as various forms - uveitis, conjunctival involvement, optic nerve involvement, and orbital involvement. All the forms of uveitis - anterior uveitis, intermediate uveitis, posterior uveitis and panuveitis - can be shown in sarcoidosis. Because clinical manifestation, prognosis and treatment are determined by the location of uveitis, it is important to classify uveitis. Conjunctival involvement is not a sight-threatening condition in general, its diagnostic value may be of use. Optic nerve is the most commonly involved cranial nerve, which can impair vision. Subjects with visual impairment without any evidence of uveitis, optic nerve involvement should be suspected. Orbital involvement, especially lacrimal gland involvement is common, and it may cause mass-effect. Besides systemic administration of drugs, there are several localized treatments for ocular sarcoidosis - topical eye drops, intra/peri-ocular injection of agents.

PURPOSE: We report a case of stromal keratitis, corneal infiltration, anterior uveitis, central retinal artery occlusion and optic neuropathy in a patient with herpes zoster ophthalmicus. CASE SUMMARY: A 73-year-old man who was hospitalized for pain and vesicles on his left face was referred to our clinic with sudden onset visual disturbance in his left eye. His best corrected visual acuity in the right eye was 0.8 and light-perception in his left eye. Relative afferent pupillary defect was found in his left eye. Slit-lamp examination showed anterior uveitis secondary to herpes zoster ophthalmicus presented with stromal keratitis. Fundus examination showed retinal hemorrhage, vitreous opacity, cherry-red spot in the fovea and optic disc swelling. Delayed arterial filling and arteriovenous transit time were observed on fluorescence angiography. He was treated with topical antiviral and steroid eye drops for stromal keratitis and anterior uveitis. He was also treated systemically with an intravenous antiviral agent and oral steroid, but visual acuity did not improve. CONCLUSIONS: Stromal keratitis, corneal opacity, anterior uveitis, central retinal artery occlusion and optic neuropathy can be complications of herpes zoster ophthalmicus.

Among blood preparations, serum has been topically used in the management of various ocular diseases in ophthalmology. Like peripheral blood serum, umbilical cord blood serum contains a high concentration of essential tear components, growth factors, neurotrophic factors, vitamin A, fibronectin, prealbumin, and oil. Umbilical cord serum can provide basic nutrients for epithelial renewal and can facilitate the proliferation, migration, and differentiation of the ocular surface epithelium. Eye drops made from umbilical cord serum have been applied to treat various ocular surface diseases, including severe dry eye with or without Sjogren's syndrome, ocular complications in graft-versus-host disease, persistent epithelial defects, neurotrophic keratopathy, recurrent corneal erosions, ocular chemical burn, and surface problems after corneal refractive surgery. Because mesenchymal stem cells from umbilical cord blood can be used to regenerate corneal tissue and retinal nerve cells, umbilical cord serum might be applied for tissue engineering and regenerative medicine in the future.

OBJECTIVE: Although removal of the anterior clinoid process (ACP) is essential surgical technique, studies about quantitative measurements of the space broadening by the anterior clinoidectomy are rare. The purposes of this study are to investigate the dimension of the ACP, to quantify the improved exposure of the parasellar space after extradural anterior clinoidectomy and to measure the correlation of each structure around the paraclinoidal area. METHODS: Eleven formalin-fixed Korean adult cadaveric heads were used and frontotemporal craniotomies were done bilaterally. The length of C6 segment of the internal carotid artery on its lateral and medial side and optic nerve length were checked before and after anterior clinoidectomy. The basal width and height of the ACP were measured. The relationships among the paraclinoidal structures were assessed. The origin and projection of the ophthalmic artery (OA) were investigated. RESULTS: The mean values of intradural basal width and height of the ACP were 10.82 mm and 7.61 mm respectively. The mean length of the C6 lateral and medial side increased 49%. The mean length of optic nerve increased 97%. At the parasellar area, the lengths from the optic strut to the falciform liament, distal dural ring, origin of OA were 6.69 mm, 9.36 mm and 5.99 mm, respectively. The distance between CN III and IV was 11.06 mm. CONCLUSION: With the removal of ACP, exposure of the C6 segments and optic nerve can expand 49% and 97%, respectively. This technique should be among a surgeon's essential skills for treating lesions around the parasellar area.

OBJECTIVETo observe the difference in the clinical efficacy on oculomotor impairment between electroacupuncture and acupuncture and explore the best therapeutic method in the treatment of this disease.

METHODSSixty cases of oculomotor impairment were randomized into an electroacupuncture group and an acupuncture group, 30 cases in each one. In the electroacupuncture group, the points were selected on extraocular muscles, the internal needling technique in the eye was used in combination of electroacupuncture therapy. In the acupuncture group, the points and needling technique were same as the electroacupuncture group, but without electric stimulation applied. The treatment was given 5 times a week, 15 treatments made one session. After 3 sessions of treatment, the clinical efficacy, palpebral fissure size, pupil size, oculomotor range and the recovery in diplopia were compared before and after treatment in the two groups.

RESULTSIn the electroacupuncture group, the palpebral fissure size was (9.79+/-2.65)mm and the eyeball shifting distance was (18.12+/-1. 30)mm, which were hig-her than (8.23+/-2.74)mm and (16.71+/-1. 44)mm respectively in the acupuncture group. In the electroacupuncture group, the pupil diameter was (0. 44 +/-0. 42)mm, which was less than (0. 72 +/- 0. 53)mm in the acupuncture group, indicating the significant difference (all P<0. 05). The cured rate was 63. 33% (19/30) and the total effective rate was 93.33% (28/30) in the electroacupuncture group, which was better than 36.67% (11/30) and 83. 333 (25/30) in the acupuncture group separately, indicating the significant difference (all P<0. 05).

CONCLUSIONElectroacupuncture presents the obvious advantages in the treatment of oculomotor impairment, characterized as quick and high effect, short duration of treatment and remarkable improvements in clinical symptoms, there are important significance for the improvement of survival quality of patients.

PURPOSE: To evaluate orbital blood flow velocities and optic nerve diameter with Doppler and gray-scale sonography in patients with acute unilateral optic neuritis (ON). METHODS: Orbital Doppler and gray-scale sonography was performed in 46 eyes of 23 patients aged 19- to 47-years with acute unilateral ON. ON was diagnosed by an ophthalmologist on the basis of clinical presentation, presence of decreased visual acuity and assessment of visual evoked potentials. The peak systolic velocity (PSV) and end-diastolic velocity (EDV), as well as the resistance index (RI) and pulsatile index (PI) of the ophthalmic artery (OA), central retinal artery (CRA), posterior ciliary arteries (PCAs) and optic nerve diameter were measured in both eyes. We compared results from affected and unaffected eyes using the paired t-test. The area under the receiver operating characteristic (ROC) curves was used to assess the diagnosis of ON based on measured blood flow parameters of the OA, CRA and PCAs and optic nerve diameter. RESULTS: The mean (standard deviation) optic nerve diameter in eyes with ON was 4.1 (0.8) mm, which was significantly larger than the 3.0 (0.4) mm diameter measured in unaffected control eyes (p < 0.001). There were no differences in average PSV, EDV, RI, or PI of the OA and CRA between affected and unaffected eyes (p > 0.05). The mean RI in the PCAs was slightly lower in the eyes with ON than in the contralateral eyes (0.60 vs. 0.64, p < 0.05). The area under the ROC curves indicated that optic nerve diameter was the best parameter for the diagnosis of ON. CONCLUSIONS: Optic nerve diameter was related to ON, but orbital blood flow parameters were not.

Infraoptic anterior cerebral artery (ACA) is an extremely rare congenital anomaly. This anomalous artery usually arises from the intradural internal carotid artery (ICA) near the level of the ophthalmic artery (OA) or rarely from the extradural ICA. This anomaly frequently harbors a cerebral aneurysm, and may involve other coexisting vascular anomalies. In the case of this anomaly, surgical treatment of the aneurysm at the proximal ACA or anterior communicating artery (ACoA) may sometimes be difficult, because the veiled proximal ACA by the optic nerve would make proximal control inconvenient and the vertical midline segment of the proximal ACA would frequently form a superiorly directing aneurysm with a relatively high position. We report on an extremely rare case of a ruptured aneurysm at the infraoptic azygous ACA, possibly having an extradural origin, accompanied by contralateral ICA agenesis, and also introduce a feasible method for treatment by Y-stent assisted coil embolization.

An infraoptic course of the anterior cerebral artery (ACA) is a rare anomaly of the anterior part of the circle of Willis. About 56 cases have been reported, often in association with cerebral aneurysm. We describe a case involving an infraoptic ACA in which a ruptured middle cerebral artery aneurysm was also present. A 52-year-old man experienced a sudden onset of severe headache without focal neurological deficits. Computed tomography demonstrated diffuse subarachnoid hemorrhage. Three-dimensional computed tomographic angiography and conventional angiography revealed a saccular aneurysm in the left middle cerebral artery. An anomalous arterial branch, originating from the right internal carotid artery at the level of the ophthalmic artery was also visible. This vessel followed an infraoptic course. The aneurysm was successfully embolized with coils. We review the literature for the possible genesis of this anomaly and consider treatment of the associated aneurysm.
