Intraretinal or subretinal fluid in the peripapillary area can be clinically visualized in conditions such as peripapillary choroidal neovascularization, optic disc pit maculopathy, and optic nerve head tumors and granulomas. Optical coherence tomography (OCT) helps to visualize peripapillary fluid in many other chorioretinal conditions such as peripapillary pachychoroid syndrome, posterior uveitis, central retinal vein occlusion, malignant hypertension, hypotonic maculopathy as well as neuro-ophthalmological conditions such as glaucoma, microcystic macular edema and disc edema due papilledema, non-arteritic anterior ischemic optic neuropathy, neuroretinitis, and diabetic papillopathy. Often, the differential diagnosis of peripapillary fluid is a bit tricky and may lead to misdiagnosis and improper management. We describe a diagnostic algorithm for peripapillary fluid on OCT and outline the salient features and management of these conditions. [ABSTRACT FROM AUTHOR]

A 28-year-old male arrived in our Ophthalmology Out patient department (OPD) with a chief complaint of bilateral sudden loss of vision in both his eyes of three days’ duration and a history of consumption of 90 mL of alcohol five days prior to the onset of symptoms. An ophthalmic examination revealed no perception of light in both eyes. Both pupils were dilated and sluggishly reacting to light. His fundus examination showed bilateral, hyperemic, and edematous discs. The veins around the disc were mildly dilated and tortuous. Magnetic resonance imaging (MRI) brain showed symmetrical hyperintensities and hemorrhages in bilateral gangliocapsular regions and signal abnormalities areas in bilateral cerebellar hemispheres, posterior part of cerebellar vermis, bilateral cingulate gyrus showing diffusion restriction which was suggestive of toxic encephalopathy and toxic neuropathy. Fundus fluorescein angiography was also done for the patient, which showed optic disc staining in the late phase suggestive of optic neuropathy. His vision improved to 20/200 in both eyes with treatment after two months.

Diabetic papillopathy (DP) is a rare ocular manifestation of diabetes mellitus. The exact etiology is not well understood, but in some cases, it may be associated with a rapid correction of the blood glucose level. There are limited case reports describing the use of intravitreal anti-vascular endothelial growth factor antibodies which have shown effectiveness in reducing disc swelling. In this case, we present the case of an 80-year-old diabetic woman diagnosed with DP during a diabetic retinopathy (DR) screening. Her visual acuity (VA) was counting fingers on her right eye and 20/160 on her left eye. At the fundoscopy, an exuberant bilateral hemorrhagic disc edema was observed, along with a nonproliferative DR. This edema was also evident in the fluorescein angiography and was documented through the optical coherence tomography. Brain computed tomography normal. She was treated with ranibizumab with significant improvement of the optic disc edema and the VA. [ABSTRACT FROM AUTHOR]

An 18-year-old female presented with sudden onset bilateral vision loss. Extensive retinal hemorrhages were seen in both eyes. Systemic examination lead to a diagnosis of acute promyelocytic leukemia. The patient was treated with all trans retinoic acid (ATRA) and other medications in the induction phase. Bilateral disc edema was noted during the second consolidation cycle with ATRA. Complete resolution of bilateral disc edema was attained in three weeks' time after discontinuing ATRA.

Purpose: To report a case of carboplatin-induced bilateral optic neuropathy in a patient with metastatic squamous cell carcinoma of the tongue. Case Report: A 65-year-old man with a history of squamous cell carcinoma of the tongue with metastasis to the right axillary lymph node treated with carboplatin and paclitaxel was evaluated for decreased visual acuity in both eyes. Visual acuity was 20/70 in the right eye and no light perception in the left eye. On dilated fundus examination, optic disc edema was present in both eyes with more severity in the left eye, flame shape hemorrhages around the optic nerve head in both eyes and cotton wool spots around the left optic nerve head. Brain and orbital MRI demonstrated enhancement of the bilateral optic nerve sheaths. He was diagnosed with bilateral carboplatin-induced optic neuropathy. Conclusion: Our findings in this case justify monitoring of patients during their course of intravenous carboplatin therapy. [ABSTRACT FROM AUTHOR]

Osteopathia striata combined with cranial sclerosis (OS-CS) is an inherited skeletal dysplasia that manifests with macrocephaly, orofacial abnormalities, thickened craniofacial bones, and vertically oriented radiodensities of the long bones. Here, we present a severe case of OS-CS in a 4-year-old girl causing optic neuropathy as shown by radiographic evidence, ophthalmic findings, and histopathology. Previous genetic testing in this patient revealed a de novo heterozygous mutation in AMER1 (c.1057C>T, p.Arg353Ter). Although the patient had a pre-existing, appropriately functioning, ventriculoperitoneal (VP) shunt, a subsequent MRI of the brain and orbits showed narrowing of the bilateral optic nerve canals secondary to osseous thickening causing bilateral optic nerve atrophy, worse on the left. The patient underwent staged bilateral orbital osteotomies, optic canal decompression, and bilateral frontal craniotomy, and at 11 months postoperatively, her vision remained stable. Conclusions: While up to 50% of the patients with OS-CS may experience hearing loss due to cranial nerve compression, we present a case of severe visual loss secondary to OS-CS-associated optic nerve compression.

Renal tuberculosis (TB) is a rare clinical disorder in the pediatric population. A 15-year-old female presented with intermittent blurring of vision in both eyes associated with fever, abdominal pain, and weight loss. Fundus examination showed bilateral disc edema. Her blood pressure was 220/110 mmHg. Renal parameters were deranged with bilaterally enlarged kidneys. Renal biopsy was suggestive of epithelioid cell granuloma with Langhans type giant cells. The patient was diagnosed with as a case of refractory hypertension due to tubercular interstitial nephritis with bilateral Grade IV hypertensive retinopathy. She was started on antitubercular therapy and antihypertensives. There was a complete resolution of disc edema 2 months following initiation of therapy. Optic disc edema can be a presenting sign in renal TB. Early diagnosis and prompt referral can be associated with good visual and systemic outcomes.

Wernicke's encephalopathy (WE) due to hyperemesis gravidarum is an under-diagnosed but potentially disastrous condition. We report a case of a young lady with hyperemesis gravidarum who developed Wernicke's encephalopathy.

A 36-year-old female presented with blurring of vision in one eye for 10 days after 1 month of an episode of COVID-19 infection. Her fundus showed disc edema with blurring of margins along with exudation around the fovea. Her C-reactive protein levels were raised. She responded well to oral steroids. A likely association with COVID-19 infection and its associated immune response was suspected.

A 29-year-old female with treated acute lymphoblastic leukemia in remission presented with blurred vision and pain on movement of the right eye. On examination, visual acuity was 20/25 in the right eye and 20/20 in the left eye. Direct ophthalmoscopy revealed that the optic disc was swollen with peripapillary hemorrhage in the right eye. The rest of the clinical examination was within normal limits. Magnetic resonance imaging demonstrated enhancement of her right optic nerve. Lumbar puncture and bone marrow examination revealed no malignant cells. Only vitreous fluid cytology showed blast cells. Intravitreal injection of methotrexate was given, and repeated vitreous tapping was normal. The vision of her right eye remained 20/20 until 1 year later when optic disc and retinal vascular occlusion was noted. Her vision deteriorated to no light perception within 2 weeks, and optociliary shunt vessels occurred. Isolated disc swelling with positive vitreous cytology can be the first and only presentation of relapsed hematologic disorders. Infiltrative optic neuropathy should be considered in the differential diagnosis of optic disc edema. Vitreous tapping could be considered as the diagnostic procedure even if the results of lumbar puncture were negative. [ABSTRACT FROM AUTHOR]

A cilioretinal artery occlusion (CLRAO) associated with optic disc edema was diagnosed in a patient seven days after the second dose of viral vector SARS-CoV-2 vaccination. The patient developed sudden blurred vision in the inferior hemifield of the right eye. His fundus examination showed retina edema at the superotemporal quadrant within vascular arcades of the right eye. Fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherent tomography angiography (OCTA) were used to confirm the diagnosis. [ABSTRACT FROM AUTHOR]

AIM: To study whether patients with progressive nonarteritic anterior ischemic optic neuropathy (NAION) present earlier than patients with stable NAION and to describe their clinical characteristics and visual outcome. METHODS: This was a retrospective chart review. All patients with NAION seen during the acute stage from January 2012 to December 2018 were reviewed. Patients were included if they had documented disc edema and follow up of at least 3mo. Patients with progressive NAION were identified if they worsened in 2 out of 3 parameters: visual acuity ≥3 Snellen lines; Color vision ≥4 Ishihara plates; the visual field defect involved a new quadrant. The clinical characteristics, time from symptom onset to presentation, systemic risk factors and visual outcome were compared to patients with stable NAION. RESULTS: Totally 122 NAION cases met the inclusion criteria. Mean age was 58.1y (range 22-74), 70% were men. Twenty cases (16.4%) had progressive NAION. Patients with progressive NAION did not differ from stable NAION in their demographics, systemic risk factors or in their initial visual deficit. At last follow up, median visual acuity was 1.0 logMAR (IQR 0.64-1.55) in patients with progressive NAION, vs 0.18 (IQR 0.1-0.63) in stable NAION (P

Neuromyelitis optica (NMO) is a rare autoimmune disease affecting nerves of the eyes and central nervous system. Etiology of NMO is yet to be completely defined. The purpose of this report is to bring to light one such unique case of NMO.

Purpose: To analyse baseline imaging characteristics and factors affecting poor visual acuity in diabetic papillopathy., Methods: This was a retrospective, observational study conducted at a tertiary eye care centre in eyes with a diagnosis of diabetic papillopathy. Demographic data including age, gender, duration of diabetes, type of diabetes, HbA1c values and other systemic co-morbidities were recorded. Baseline best corrected visual acuity (BCVA), and various imaging characteristics were noted., Results: 37 eyes of 22 patients with diagnosis of diabetic papillopathy were included [mean age of 46.6 ± 13.5 years, five (22.7%) females and 17 (77.3%) males]. Bilateral involvement was seen in 15 (68.2%) patients. The mean baseline BCVA was 0.51 ± 0.49 logMAR (Snellen equivalent 20/60). Two eyes (5.4%) had features of concurrent mild NPDR, 9 eyes (24.3%) had moderate NPDR, 10 eyes (27.03%) had severe NPDR while 16 (43.2%) other had PDR. All eyes had optic disc edema while 4 had disc pallor at presentation. Telangiectatic vessels/ neovascularisation of disc was present in 17 eyes (45.9%) detected either clinically or on optical coherence tomography (OCT) angiography. 11 (29.7%) eyes had a peripapillary cuff of subretinal fluid accompanying the disc edema. Sixteen eyes (43.2%) had centre involving macular edema seen on OCT. In eyes with a macular edema, the mean central macular thickness was 407.4 ± 71.42 microns at baseline. On assessing the baseline factors that contribute to the final visual acuity, presenting visual acuity was the only variable found to be statistically significant., Conclusion: Although described to have good visual outcome, eyes presenting with poor visual acuity tend to have worse vision on follow up. This may aid in prognosticating and guiding management plan., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Ocular manifestations of COVID-19 are still being studied. Posterior segment involvement in viral entities is either direct viral involvement or a delayed immune response to the antigen. A 22-year-old woman presented with history of perceiving absolute inferior scotoma in the right eye for 4 days and history of fever and sore throat 10 days ago. Fundus examination revealed disc edema and vessel tortuosity. Humphreys Field Analyzer confirmed inferior field defect and Optical Coherence Tomography showed superior, nasal and inferior retinal nerve fiber layer thickening in the right eye. Patient was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse transcription polymerase chain reaction (RT-PCR) testing. Patient received three doses of injection methylprednisolone over 3 days. There was subjective resolution of scotoma reported 3 weeks posttreatment. We bring forward the first reported case of parainfectious optic neuritis associated with COVID-19.

Objective The objective is to correlate visual outcomes in malignant hypertensive retinopathy with changes in systemic causative factors and spectral domain optical coherence tomography (SD OCT) morphologic parameters. Materials and methods This is a prospective observational study including patients presenting within two weeks of acute rise of systolic blood pressure (SBP) ≥ 180 mm Hg or diastolic blood pressure (DBP) ≥ 120 mm Hg and with posterior segment involvement in both eyes. Baseline SBP, DBP, mean arterial pressure (MAP), best corrected visual acuity (BCVA), and SD OCT parameters such as central macular thickness (CMT), subfoveal choroidal thickness (SCT), and sub-retinal fluid (SRF) height were measured at presentation and followed monthly up to three months. These variables at baseline and three months were compared and correlated. Results Thirty-three patients (66 eyes) having malignant hypertension were included in the study. Diverse clinical presentations noted among patients were optic disc edema, hard exudates in the macula, peripapillary splinter hemorrhage, cotton wool spots, Elschnig spots, exudative retinal detachment, optic neuropathy, and severe exudative retinopathy. SD OCT shows hyperreflective dots and intraretinal fluid with or without SRF. At three months, the mean SBP, DBP, MAP, CMT, SRF, and SCT all decreased significantly from baseline (p<0.001). Changes in SBP, DBP, MAP, and SCT correlated significantly with changes in BCVA (p<0.001). Conclusion In malignant hypertensive retinopathy, macular edema with SRF is the major cause of mild-to-moderate decrease BCVA at presentation, but macular ischemia, exudative RD, and optic neuropathy can cause a significant decrease in vision. A decrease in SBP, DBP, MAP, and SCT correlate significantly with visual outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Purpose: To report a rare case of optic neuritis with spine demyelination following H1N1 virus infection. Observation: A 66-year-old female presented with decreased vision in both eyes (left > right) following a recent episode of fever and flu. She was diagnosed as H1N1 infection confirmed by viral antigen analysis of throat swab. On examination, she had a profound vision drop in the left eye with optic disc edema. MRI brain and orbit revealed bilateral optic nerve and frontal dural thickening with a ring-enhancing lesion in the right frontal lobe. MRI spine showed long cord signals at T1-T7 suggestive of demyelination. The patient had a complete recovery of vision and visual fields after intravenous and oral steroids. Conclusion/Importance: Influenza A virus can manifest with a wide range of symptoms including flu-like illness to neurological complications. This case highlights optic neuritis as a presenting feature of H1N1 infection.

Optic disc oedema is a common clinical problem where the ophthalmologist plays an important role in the diagnosis, management. Many optic nerve diseases can cause disc oedema like papilloedema, papillitis, anterior ischaemic optic neuropathy, central retinal vein occlusion, optic nerve head drusen etc. It is important to differentiate pseudoneuritis as in hypermetropia from true disc oedema. The clinical features, fundus examination sometimes may not give the correct diagnosis. Fundus fluorescein angiogram helps to differentiate pseudo from true disc oedema. However it is an invasive procedure. With newer technologies like optical coherence tomography which helps to image the optic disc, it is possible to differentiate pseudo from true disc oedema, also to recognise the aetiology of disc oedema. In this review article we are highlighting the OCT findings in various causes of disc oedema.

Differentiating glaucomatous and non-glaucomatous optic neuropathy can be challenging even to an experienced clinician and it is even more complex to identify early ophthalmic manifestation of neurological lesions when the optic nerve is already jeopardized by advanced glaucoma. This is a case of a patient with juvenile open-angle glaucoma with advanced glaucomatous cupping who developed an intracranial tuberculoma and subsequent obstructive hydrocephalus. Subtle edema identified in an almost totally damaged nerve, coupled with a history of headache and tinnitus, was the clinching factor prompting early treatment in the form of ventriculoperitoneal shunting and antituberculous therapy. Detailed history, systematic clinical exam, and appropriate imaging are imperative in reducing morbidity and sometimes mortality associated with these neurological conditions.

Purpose: To report a Rathke's cleft cyst (RCC) presenting as unilateral incomplete cavernous sinus syndrome and disc edema Method: Case report with literature review Results: We present an 18-year-old girl who has been experiencing intermittent binocular diplopia for 1 month. Upon examination, the best corrected visual acuity was 20/20 (OU). Pronounced limitation of ocular motility with ptosis in her right eye was noted. Her pupil constricted normally. However, a relative afferent pupillary defect in the right eye was observed. Fundus examination showed disc edema in the right eye without peripapillary hemorrhage. Moreover, her thyroid function and acetylcholine receptor antibody levels were normal. Brain magnetic resonance imaging revealed a 1.6-cm mass at the suprasellar fossa and optic nerve sheath of right eye enhancement. She underwent transsphenoidal surgery, and pus-like formation was noted. Pathological findings were consistent with RCCs. After the cyst was removed, her ocular motility remarkably improved and ptosis subsided. Conclusion: A case of RCC presenting as multiple cranial nerve palsy was reported. RCCs are benign and usually asymptomatic. Symptomatic RCCs often manifest as headache or visual problems, such as reduced visual acuity and visual field defect. Multiple cranial nerve involvement is uncommon and indicates inflammation or compression of the cavernous sinus and optic nerve. Neuropathy may resolve after surgery; therefore, surgery is indicated for symptomatic RCCs. Further, RCC should be included in the differential diagnosis of patients with disc edema.

Intraocular manifestations of malignancies and lesions elsewhere in the body are widely reported. The ophthalmic features can be due to metastasis in case of malignancy or due to the secondary effects of the lesions causing hematological or neurological complications. On a few occasions, the ocular features predominate and even precede the characteristic features pertaining to the underlying conditions. In such cases, an ophthalmologist can be the first clinician to encounter the patients. The ocular presentations can be bizarre or even misleading, but on careful history elicitation and examination could unveil life-threatening diseases lying hidden elsewhere inside the human body. Here, we present two case reports, where the ocular features helped in the diagnosis of primary pathology elsewhere.

This case highlights the atypical presentation of Foster-Kennedy syndrome (FKS) associated with Neurocysticercosis (NCC), a prevalent cause of space-occupying lesions in areas endemic to the parasite. We report a newly diagnosed case of NCC in a 13-year-old boy who presented with a one-day history of abnormal movements of the left side of the body and no ocular complaints. Fundus examination of the patient revealed temporal disc pallor and a cup disc ratio (CDR) of 0.6 in the right eye suggesting unilateral optic disc atrophy and a hyperaemic disc with CDR 0.3 and blood vessel tortuosity in the left eye suggesting contralateral impending disc edema, mimicking the classic triad of FKS. He was diagnosed with NCC based on clinical features and radiological findings and was started on Carbamazepine (400 mg), Prednisolone (60 mg), Albendazole (400 mg), Acetazolamide (750 mg), and Vitamin B12 complex.

Bilateral optic disc edema in a diabetic patient may be caused by diabetic papillopathy. We herein report on a patient with bilateral optic disc drusen simulating diabetic papillopathy. A 55-year-old patient with type 2 diabetes presented with decreased vision of 1-month. Diabetic papillopathy was initially considered as there was disc edema in both eyes with focal hemorrhages at the disc margin and mild visual loss. Ultrasound of the optic nerve head revealed optic disc drusen in both eyes and this was also confirmed by the control photograph. Optic nerve head drusen should be considered in the differential diagnosis of a diabetic patient presenting with disc edema.

Human papillomavirus (HPV) infection is strongly associated with several human cancers; the most known genotypes involved being HPV 16 and HPV 18. We report the detection of HPV 52 in a sample taken from a 47-year-old patient with squamous cell carcinoma of the conjunctiva of the left eye. The method used for the detection of HPV was real time polymerase chain reaction. The evolution was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence.

Pellucid marginal degeneration (PMD) is an uncommon cause of inferior peripheral corneal thinning disorder, characterized by irregular astigmatism. We analyzed a case of bilateral PMD patient and treated one eye with corneal collagen cross-linking (CXL) therapy. Corneal topography was characteristic for PMD. Visual acuity, slitlamp examinations, tonometry, and corneal thickness were observed. Simulated keratometric and topographic index values were detected with corneal topography. Uncorrected, LogMAR visual acuity has improved from +0.8 to +0.55 during the 6 months and +0.3 during the 8 months follow-up after CXL. Pachymetry values and intraocular pressure showed no changes. Keratometric values and topografic indexes disclosed no progression of the disease. CXL may postpone or eliminate the need of corneal transplantation in cases with PMD.

Rhodotorula mucilaginosa rarely cause keratitis in immunocompromised individuals. A 30 year old male with history of minor trauma presented with cotton wool like stromal infiltration and hypopyon in left eye. Microbiological examination of corneal scraping showed fungal hyphae and yeast cells in direct smear. Molecular identification of the organism was performed which showed 100% homology with Rhodotorula mucilaginosa. Management of these cases is difficult often necessitating surgical procedures. However further reports are necessary to understand the disease and establish a treatment protocol.

Orbital complications due to ethmoiditis are rare in neonates. A case of orbital abscess due to acute ethmoiditis in a 28-day-old girl is presented. A Successful outcome was achieved following antimicrobial therapy alone; spontaneous drainage of the abscess occurred from the lower lid without the need for surgery. From this case report, we intend to emphasize on eyelid retraction as a sign of neonatal orbital abscess, and to review all the available literature of similar cases.

Purpose: To describe an adult with chickenpox resulting in systemic vasculitis and bilateral retinal vascular occlusions. Methods: Single case report. Results: A 58-year-old man with chickenpox complicated by disseminated varicellazoster systemic and retinal vasculitis resulting in a combined arterial and venous occlusion in one eye with multiple branch retinal vein occlusions in the other eye. There was no evidence of retinitis. The patient systemically improved after treatment with acyclovir and steroids; however, his vision remained poor. Conclusion: Chickenpox can be associated with systemic vasculopathy and may rarely result in multiple systemic and ocular infarcts, including severe retinal vascular occlusions.

Hypertensive retinopathy is seen frequently in patients with systemic hypertension and is usually asymptomatic. An acute rise in blood pressure may lead to exudative changes in the form of macular edema, hemorrhages, and serous macular detachment that can lead to visual decline. The authors report prompt resolution of exudative changes in a case of hypertensive retinopathy following intravitreal bevacizumab.

We report a case of ocular tuberculosis (TB) which initially presented with disc edema and was mistaken for optic neuritis. With no definite pathology being identified, the patient was treated on the lines of optic neuritis with intravenous (IV) steroid with beneficial effect. Ocular TB was suspected when he presented later with a subretinal abscess. Based on positive Mantoux, QuantiFERON TB gold results and radiographic findings, a diagnosis of subretinal abscess of presumed tubercular etiology was made. The patient was successfully treated with anti-tubercular therapy. To the best of our knowledge, this is the first case report of ocular TB presenting as disc edema followed by subretinal abscess.

Optic neuritis is an inflammatory condition of the optic nerve characterized by a sudden onset of unilateral visual loss, usually affecting young females. Demyelination associated with multiple sclerosis (MS) is the most common cause in regions where MS is prevalent; while in other places, there are a substantial proportion of cases where infective or autoimmune causes are seen. Optic Neuritis Treatment Trial (ONTT) was the first major study that provided information on the natural history, role of steroids in treatment and risk of development of MS. Subsequently, numerous clinical trials have evaluated different modalities of management of optic neuritis and MS. The Controlled High-Risk Subjects Avonex Multiple Sclerosis Prevention Study (CHAMPS); the Prevention of Relapses and Disability by Interferon β-1a Subcutaneously in Multiple Sclerosis (PRISMS) Trial; and, most recently, the Betaferon in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) Study have provided large amount of information on the natural history of optic neuritis and management options available. However, due to the low prevalence of MS reported in Asian studies, high cost of therapy and indefinite time period of treatment, it may not be cost effective to start interferon therapy in most cases.

A 35-year-old female was referred to our hospital with bilateral loss of vision of two days duration. She gave history of consumption of about 150 ml of neem oil five days back.Examination revealed no perception of light in both eyes. Both pupils were dilated and sluggishly reacting to light. Her fundus examination showed bilateral hyperemic, edematous discs and also edema extending along the superior and inferior temporal vascular arcade. Magnetic resonance imaging (MRI) scan showed bilateral putaminal regions with altered signal, hypointensities in T1-weighted images, hyperintensities on T2-weighted, images and hyperintense on Fluid Attenuation Inversion Recovery (FLAIR) images suggestive of cytotoxic edema due to tissue hypoxia. Her vision improved to 20/200 in both eyes with treatment after two months. This is the first case report of such nature in the literature to the best of our knowledge.

A 65-year-old lady presented with decreased vision in left eye since seven months. Vision was 6/9 in right eye and 6/36 in left. Examination revealed idiopathic, full-thickness macular hole in left eye; confirmed by optical coherence tomography (OCT). Patient underwent phacoemulsification with intraocular lens (IOL) implantation, vitrectomy, internal limiting membrane (ILM) peeling and 14% C 3 F 8 gas injection. OCT repeated after six weeks revealed type II closure with cuff of subretinal fluid. Four weeks later, patient underwent fluid-gas exchange with 14% C 3 F 8 gas and postoperative positioning. OCT was repeated after two weeks, which showed complete closure of the macular hole. OCT can help in selection of eyes for re-surgery that stand a better chance for hole closure. Macular holes with cuff of subretinal fluid are probably more likely to close on re-surgery than those without. However, larger studies with longer follow-up are required to validate this finding.

We report the first case, in Medline-based literature, of conjunctivitis caused by gram negative diplococcus, Neisseria sicca. Although it is not widely accepted as such, isolation from cultures of repeated eye swab samples suggests that N. sicca may be a pathogen in conjunctival infections. Positive culture for this organism should not be readily dismissed. Such conjunctivitis responded favorably to treatment with netilmicin eye drops.

A 57-year-old male patient visited our clinic for decreased visual acuity in the right eye for 10 days. He denied any trauma history, but recalled that the symptom developed after straining. He had undergone uncomplicated phacoemulsification and posterior chamber intraocular lens (IOL) implantation in the bag of the right eye 11 years ago. The IOL was a three-piece silicone polyimide-haptics design. On slit-lamp examination, the IOL optic and proximal part of nasal fractured haptic were found in the anterior chamber. The distal part of fractured haptic was observed in the capsular bag. He underwent IOL exchange. The fracture site of the haptic was near the optic-haptic junction. This is the unique case report of a spontaneous fracture of an implanted posterior chamber polyimide IOL haptic, which implies the possibility of IOL haptic fracture in various haptic materials.
